Title
Method and apparatus for push and pull distribution of multimedia
Abstract
The present specification discloses a multimedia distribution system and method. The system and method has a producer workstation, a delivery server, a high-bandwidth one-way satellite transmission system, a terrestrial two-way communication system (including use of the Internet), a plurality of satellite affiliate workstations, and a plurality of terrestrial client workstations. The delivery server receives digital information (envelopes and associated media files) from the producer workstations for delivery of the information to the affiliate and client workstations addressed in the envelope. The affiliate and client workstations provide the delivery server with confirmation of delivery of each received envelope and its associated files. In the absence of receipt of confirmation of delivery, the delivery server re-sends the unconfirmed envelope and associated files to the non-confirming affiliate or client workstation by a two-way terrestrial connection or by a manual system, such as a dub-and-ship service. The delivery server has the ability to push content to affiliates, push-pull content to affiliate and clients, to conventionally pull content from the delivery server, and push the content to affiliates and clients by manual delivery services. The disclosed system and method utilize a unique envelope and addressing protocol and a unique broadcast file transfer protocol for distribution to affiliate workstations by one-way satellite broadcast. The disclosed system and method also make significant use of the TCP/IP, IGMP, and Ethernet protocols and information distribution techniques.

Description
FIELD OF THE INVENTION

The present invention relates to the distribution of multimedia from one location to another. More particularly, this invention relates to the automated distribution of digital media, most preferably by "pushing" media to receiving units and `pulling` media from distributing units.

BACKGROUND

There has long been a need for efficient methods and systems for distribution of differing types of media such as data, images, audio, or video information. In attempting to fulfill this need, a wide variety of types of systems have been developed, from manual systems such as postal and express physical delivery systems to digitized systems such as those built around wide area computing networks (WANs) and the Internet.

Manual systems suffer from a wide variety of problems, such as high cost, limited reach, unreliability, and time delay. The Internet and traditional e-mail types of distribution systems have become a much more omnipresent vehicle for distributing media, but the Internet presents significant problems for those seeking to reliably, efficiently, and quickly distribute digital media, particularly voluminous media files, to a variety of users.

In this regard, the Internet does presently support certain types of `push` distribution and `pull` distribution. Internet facilities such as traditional e-mail allow an Internet user to `push` content out to many other Internet users (but usually not other types of users) through the Internet. Through the web and other facilities, the Internet allows Internet users (again, not others) to log onto web sites and `pull` or download content from the sites. The Internet `pull` model of distribution is unreliable and often quite untimely because it requires the receiving party to have access to the Internet and to initiate on its own the `pull` or media download. Similarly, the Internet `push` model of distribution is either: (i) unreliable and untimely because it does not accomplish any delivery at all until the intended receiving party logs onto the Internet and retrieves the pushed e-mail content from the party's e-mail facility; or (ii) expensive if the `push` model is made more reliable by a permanent connection to the Internet by all desired receiving parties.

Moreover, while the Internet can serve as an effective platform for distribution of relatively small e-mail messages to those who have corporate or educational LANs permanently connected to the Internet 24 hours per day, 7 days per week, the Internet is not effective when timing of the reception is important and the sending and receiving entities either do not both have access to the Internet or are not both on-line to send and receive when needed. The Internet also suffers from well known bandwidth and other constraints that make it difficult, and often impossible, to rely on the Internet to distribute large media files, such as those containing images, audio, or video, for use by others who must receive and use such files in a timely fashion.

One approach to solving the problem of distribution of digital media has been to develop private wide area networks ("WANs") independent of the public Internet. Examples of these types of systems include corporate WAN's and the private WAN audio distribution systems deployed by companies like Digital Courier International and Musicam Express. (See U.S. Pat. No. 5,694,334 and the commonly-assigned co-pending application Ser. No. 08/705,797, filed Aug. 30, 1996, entitled "Audio File Distribution and Production System"). These private WANs often consist of networks of (often specialized) personal computers linked through dedicated, private telecommunications types of links in order to produce and distribute digital information and media from one computer on the network to another.

These types of prior art WAN's have limited reach since they usually are connected only to those users who have systems connected to the WAN. They also typically have required dedicated telecommunications connections for each machine on the WAN in order to assure accessibility of, and push distribution to, each machine on the WAN. They also typically have required use of substantial expensive proprietary or non-standard software systems in order to reliably distribute voluminous media information, particularly audio or video content, throughout the WAN.

In addition, these prior art systems have typically required deployment of many thousands of expensive, customized PC's for use by each receiving or producing entity on the WAN. These types of WANs have thus not only required huge expense and effort required to manufacture, deploy, and install the customized PC's to establish the WAN and to achieve the distribution sought by the WAN, but also inherently limited the ability to easily and economically upgrade the installed base of PC's and other networking equipment over time when hardware upgrading is required or advisable (as it so often is in the rapidly evolving field of personal computers and telecommunications).

BRIEF SUMMARY OF ASPECTS OF THE INVENTION

The applicants have developed an integrated and automated system and method for reliably distributing digitized media information (preferably any type of digitized media information whatsoever) to multiple recipients. The present system and method includes push distribution through terrestrial and/or extraterrestrial facilities with confirmation of delivery from the recipients, and a combination push-pull distribution by a contact with the intended recipient (preferably without incurring any substantial communication charges) and a responsive pull or downloading of information by the recipient, also with confirmation by the recipient.

The applicants' system and method also preferably includes pull distribution, independent of the push/pull, allowing intended recipients to call in on their own and then select and download information. The system and method further preferably includes an automatic fallback method of physically shipping information to intended recipients that have not confirmed receipt of the media information through the other push, push/pull, or pull methods.

The preferred system and method also provides that many of those connected to the system may be producers of content for distribution to others through the system. In this fashion, producers can also be recipients of content from others on the system.

The preferred system and method also includes local hubs or proxy servers for the collection of content locally and distribution of that content to others connected to the hub, or to other hubs and their affiliated recipients. The system and method may also provide the ability to fax selected textual or graphic information to intended recipients.

The applicants' preferred apparatus and method also utilizes a flexible and powerful broadcast file transfer protocol for transfer of files through a one-way broadcast system, such as a one-way satellite system, into a TCP/IP (two-way) network.

These and other aspects of the present invention will become apparent as the specification proceeds. In this regard, it is to be understood that the scope of the invention is to be determined by reference to the claims and not to this Brief Summary.

OBJECTS AND ADVANTAGES OF THE INVENTION

It is an object of the present invention to provide a reliable and automated system and method for distribution of media information or content.

It is yet another object of the invention to provide such a system that can be used to distribute audio or text for national radio broadcasters.

It is an advantage provided by the applicant's invention that the present system and method can reliably distribute any type of media--data, images, audio, video, or multimedia.

Yet another advantage is that the present method and system can economically push content to recipients through efficient broadcast mediums such as satellite broadcasting systems.

A further advantage is that the present method and system provides confirmation of receipt to the party pushing or broadcasting the content.

A still further advantage is that the present method and system can also remotely activate intended recipients to perform a pull or download of content from the system, thus reducing or eliminating the need for continuous telecommunications connections typically required to push content to intended recipients, thereby also reducing or eliminating associated communication expenses.

An additional advantage it that the present method and system can allow recipients to independently pull permitted content whenever desired by the recipients.

Yet another advantage is that the present system works in conjunction with well established and widely available aspects of the Internet while not being dependent on the Internet to accomplish distribution of content, particularly high bandwidth content.

It is also an advantage of the present system and method to provide a fall-back manual system of delivery of content when all else fails or the intended recipient is not a part of the system.

Another advantage is that the present system and method allows the distributor and recipient to utilize or refrain from utilizing the Internet to accomplish distribution by, for example, accomplishing an extraterrestrial satellite broadcast to permissioned reception systems or by direct terrestrial connection independent of the Internet.

A related advantage is that the present system and method is very flexible and economical for both the system owner and operator and those who utilize the system to distribute content.

Yet another advantage is that the present system and method is easy to implement and does not require, or reduces the need for, costly hardware deployment or upgrades by the system owner or administrator over time.

An additional advantage is that the system and method can quickly, efficiently, and reliably distribute large, high bandwidth files, particulary audio or video files.

A related advantage is the ability of the system and method to broadcast files through a one-way broadcast network and feed the broadcast files into a two-way or TCP/IP network.

A yet additional advantage is that the present system and method also allows the distributor of the information to prioritize the information to be distributed in order to achieve the most economical distribution available in view of the prioritization, and to customize the contents of the package to reflect the identity and preferences of the sending party.

Another advantage of the present system and method is that those who use the system and method may readily, quickly, and economically access the central distribution management system to determine the nature and status of content provided to the management system for delivery to users.

Yet an additional advantage is that the producers and users of content may readily preview content produced or delivered to the user by the system and method.

There are many other advantages of the present invention. They will become apparent as the specification proceeds. It is to be understood, however, that the scope of the invention is to be determined by reference to the claims and not by whether a claimed embodiment necessarily achieves all the objects or advantages stated herein for the applicants' preferred embodiment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIG. 1, the applicants' preferred system and method generally consists of producer PC workstations, e.g., 12, 14, connected by two-way terrestrial telecommunications lines, e.g., 13, 15, to a delivery server, which is connected by a one-way satellite connection, generally 18, to satellite affiliate PC workstations, e.g., 20, and by two-way terrestrial telecommunications lines, e.g., 22, 24, 26, to both the satellite affiliates, e.g., 20, and general clients, e.g., 28, 30. The two-way communications lines, 13, 15, 22, 24, 26 may be POTS (plain old telephone system), ISDN, Frame Relay, xDSL, or T1 lines. The two-way communications lines 13, 15, 22, 24, 26 may connect to a terrestrial WAN (wide area network) 32, to which the delivery server 16 is also connected. The WAN 32 may consist of a private network (such as an intranet) or the public Internet.

The one-way satellite connection 18 provides a high-bandwidth vehicle for distribution of media files, particularly larger audio or video files, to affiliates, e.g, 20, and clients, e.g., 28, 30, such as radio or television stations. Because the satellite connection 18 is only a one-way connection, the connection 18 can suffer from link errors, lack of acknowledgement, and availability problems. As will be explained in greater detail below, the applicants' system and method thus also provides two-way connections 13, 15, 22, 24, 26 for confirmation of delivery and back-up telecom delivery. The system and method also includes a fall-back manual delivery facility when automated delivery cannot be accomplished through the facilities shown in FIG. 1.

With continuing reference to FIG. 1, the delivery server 16 consists of six 400 MHz Pentium II IBM-compatible PC's (not shown), two of which constitute redundant file servers, two of which constitute redundant communications servers, and two of which constitute redundant system administration servers. The file servers (not shown) each have a 100+GB hot swappable hard drive, and run Windows NT File Server. The communications servers (not shown) each have a telephone modem pool (TAPI compliant), an ISDN modem pool (TAPI compliant), and a T1 adapter, and run Windows NT Server. The system administration servers each have a 6 GB hard drive and run Windows NT, POP3 Server, FTP Server, WWW Internet Server, Octopus real-time mirroring, and system software described in greater detail below. The file servers, communications servers, and administration servers are all interconnected on a 100 MHz Ethernet Local Area Network (LAN) 39, with standard Ethernet LAN cards mounted in each such server in a fashion well known to those of skill in the art.

The producers, e.g., 12, 14, preferably consist of an IBM compatible Pentium PC, with 4 GB of hard disk space, 64 MB of RAM, a color monitor, a mouse, a keyboard, 2 or more serial ports, an ISDN modem connected to an ISDN line, and DAC Card (by Musicam USA, Holmdel, N.J.) or Digigram Card (with suitable driver for the particular card installed on the workstation), and stereo speakers. The producers also are loaded with off-the-shelf software such as Windows NT Workstation 4.0 or higher, Microsoft Internet Explorer 4.0 or higher, Microsoft Mail, and a TAPI compliant modem driver.

The producers, e.g., 12, 14, produce electronic, digital packages 34 of media information (not shown in FIG. 1), which the delivery server 16 then stores and delivers to end-user satellite affiliates, e.g., 20, and clients, e.g., 28, 30, pursuant to instructions contained in the digital media packages 34. As will be explained below, the digital media packages 34 can include any type of digital media whatsoever, such as audio, video, text, hypertext, images, programs, data files (such as the addressing instructions or destination address list noted above or other data), etc. For example, for a radio broadcasting application, the package 34 will include one or more 30 or 60 second digitized audio advertisements (also called "spots"), a faxable instruction list, purchase order references, and an address list.

As will also be explained in further detail below, the delivery server 16 checks the contents of each digital package 34 and ensures that any value-added services required for the package 34 have been performed prior to forwarding the package 34
pursuant to the addressing instructions (not shown in FIG. 1). The delivery server 16 thus checks to make sure that the digital package 34 includes an address list and all required contents for the package 34. When received by an affiliate 20 or client
28, 30, the affiliate/client user interface allows the user to display on the PC screen the packages 34 the affiliate or client 20, 28, 30 has received and their associated content, and to organize, preview, or otherwise utilize the digital media files contained within the packages. In the radio broadcasting application, for example, the affiliate or client 20, 28, 30 may play and broadcast the received audio content by merely clicking on the file indicator for the audio content, as explained below. The satellite connection 18 of the preferred embodiment is shown in FIG. 2. The delivery server's redundant file server, e.g., 36, maintains a file system 38 of packages or envelopes 34 and their associated media files. The file server 36 runs. Broadcast File Transfer Protocol ("BFTP") service (explained below) and is connected by two-way TCP/IP connection 39 to a TCP/IP router 40, that supports IGMP version 2 mutlicasting. The router 40 is preferably a CPA 2503 router made by Cisco Corporation.

The multicast router 40 is in turn connected by a synchronous connection 42 to a StarGuide.RTM. VIF card in a StarGuide MX3.RTM. Multiplexer or Mux 44 (all StarGuide.RTM. products identified herein are available from StarGuide Digital Networks, Inc., Reno, Nev., and San Diego, Calif.). The output of the Mux 44 is fed through a satellite uplink 46, then through a third party satellite 48, and into a satellite downlink 50 in a fashion, and with additional associated equipment (amplifiers, modems, LNB's, etc. (not shown)), well known to those skilled in the art. The satellite signal is then fed from the downlink 50 into a pre-permissioned StarGuide II.RTM. Satellite Receiver 52 in a fashion well known to those skilled in the art. The Receiver 52 has a StarGuide.RTM. Ethernet Card (not shown). The StarGuide II.RTM. Receiver 52 thus demultiplexes the signal received from the satellite 48 and sends the IP portion of the signal (called a "service") to the StarGuide.RTM. Ethernet Card. In turn, the Ethernet Card provides TCP/IP IGMP multicast protocol output through a 10-Base-T Ethernet cable 54 to a satellite affiliate PC, e.g., 20. Preferably the TCP/IP uplink connection 38 and TCP/IP downlink connection 54 is an Ethernet network or similar connection, which are well known to those skilled in the art.

With this equipment, the envelopes and associated media files 34 may be broadcast efficiently by satellite to those StarGuide II.RTM. Receivers 52 pre-permissioned (through the StarGuide.RTM. NMS that controls the Mux 44) to receive the broadcast so that the affiliate PC's, e.g., 20, associated with each such permissioned Receiver 52 can receive and store the received envelope and associated media files 56 in a file system 58 on the affiliate PC, e.g., 20. In this regard, the BFTP protocol (explained below) ensures that the received envelope and media files 56 are identical to the transmitted envelope and media files 34.

With reference to FIG. 3, the system 10 of FIGS. 1 and 2 actually delivers more than just envelopes, e.g., 34, with associated media files. The system actually delivers packages of information, e.g., 60, which include an envelope 61, the associated media or data files 62, and optionally a home HTML page 64 (which preferably includes the producer's logo or web-page indicia). The envelope 61 is an ASCII text file that includes a unique package identifier, a producer account identifier, a reference to the home HTML page, a listing of associated media files and logo, a client or affiliate address list, and other ancillary information such as date, priority, media file description, file code, and file size. The envelopes, e.g., 61, are delivered through the terrestrial portion of the network or system 10 via common e-mail protocols such as the SMTP or POP3 protocols. As noted above, the envelopes 61 addressed for satellite affiliates are also broadcast over the satellite 48 using the BFTP protocol.

With reference now to FIG. 4, a producer workstation, e.g., 12, includes third-party production tools 66 such as an audio encoder (preferably, a Musicam USA Dac card, a Digigram card, or other MPEG software or hardware encoder), a video encoder, and a word processor. For audio and video files generated by the encoders, the resulting audio or video files have ISCI-identifiers, which are well known to those skilled in the art, and all the produced files, e.g., 68, 70, 72, are stored on the producer's hard drive 74. Through use of the producer packager software 76, an operator of the producer 12 utilizes standard Windows 95 or NT drag and drop tools to assemble the media files 68, 70, 72 into a package 60, such as shown in FIG. 3 and described above. The operator of the producer workstation 12 preferably next selects the client or affiliate names from a global address list 78 (automatically downloaded to the producer 12 periodically by the delivery server 16) and also possibly from a private address list (not shown) stored on the producer 12. Addresses that are private and not global will receive packages and files by manual, not automated, delivery as described below. Whenever the operator addresses a package for delivery to an address that is not on the global list, the producer software warns the operator of the inability to send to that address other than by such manual means.

The packager application 76 adds the other information to the package 60 such as shown in FIG. 3, and the operator of the producer workstation 12 may hit a "send key" (not shown) on the user interface for the application 76. This causes the packager application to queue the package 60 for immediate submission to the delivery server 16. A submitting or outbox agent 80 on the producer 12 then calls into the delivery server 16 via a two-way telecommunications line 82 supporting the TCP/IP protocol. Preferably the telecommunications line 82 is an ISDN or faster connection. The outbox agent 80 then utilizes the FTP protocol to transfer all media or data files, e.g., 68, 72, in the package 80 to the delivery server 16 and simultaneously e-mails the envelope for that package 80 to the delivery server 16. The producer 12 relies on its own production and Windows 95 or NT file management tools in order for any operator to delete media files generated by the producer 12.

With reference to FIGS. 4 and 5, the delivery server 16 runs, among other things, a mailman software agent 83, a traffic cop software agent 84, a satellite software agent 86, and web-site software 88. The mailman agent 83 continuously scans its software inbox 90 for envelopes, e.g., 60, submitted by producers (not shown in FIG. 4). On detection of an envelope 60 in the inbox 90, the mailman agent 83 reads the envelope 60, determines the identity of the associated files 68, 72, and verifies that the delivery server 16 has received all files 68, 72 identified in the envelope 60, completed any value-added services for the envelope 60 or its associated files 68, 702, and stored them on a hard disk 91 on the delivery server 16. After all such files 68, 72 are stored on the hard disk 91, the mailman agent 83 e-mails the envelope 60 to all clients, e.g, 92, 94, 96 addressed in the envelope 60, according to addresses stored in a delivery addressing database 98 also stored on the delivery server
16. In the event that any client 92, 94, 96 is also a satellite affiliate 20 as explained above, the mailman agent 83 also submits the package 76 (i.e., the envelope 60 and its associated media files 68, 72) to the satellite agent 86, which queues the package 76 for repeated broadcasting over the satellite 48 to the satellite affiliates addressed in the envelope 60. As soon as the satellite agent 86 completes the satellite broadcast of the package 76, it flags the package 76 as sent to the satellite affiliate 20.

Referring again to FIGS. 4 and 5, in the event that either (i) any client 92, 94, 96 is not on the global address list maintained in a database 98 on the server 16, or (ii) the server 16 (i.e., the traffic cop agent 84) has not received confirmation of delivery from a given client, e.g., 92, or satellite affiliate within a predetermined time after receipt of the package 76 by the server 16, the mailman forwards the envelope 60 to a "duplication house" outbox on the server 16, for subsequent forwarding of the envelope 60 and its associated files 68, 72 to the duplication house for manual delivery to each such client or affiliate. Thus, the traffic cop agent 84 monitors its inbox 100 for e-mail confirmation, e.g., 102, 104, of the receipt of packages, e.g., 76, by the clients to whom the packages have been addressed as explained above. On receipt of such confirmation 102, 104, the traffic cop agent 84 updates the addressing and delivery database 98 with a confirmation of the delivery.

The server's web-site software 88 maintains a standard, Internet-accessible web site (not shown) via a modem pool and Internet connections (not shown) maintained on the server 16 in a fashion well known to those skilled in the art. The web-site provides authorized producers, clients, affiliates, and others (not shown) with the ability to log-in to the server web-site by use of an account number and password, and to view information about the status of their packages managed or delivered by the server 16. Standard web-site browser tools (such as the Microsoft Internet Explorer and Netscape Navigator) allow the producers, clients, affiliates, and other permitted users to view their account and package delivery information on the server web-site, twenty-four hours per day, seven days per week.

The web-site software 88 provides the following search capabilities for those clients or affiliates who log into the web-site on the server 16:

Search/sort by producer's purchase order number

Search/sort by submission date

Search/sort by server assigned package identification

As a result of the password protection on the web-site, those who access the site with their password are granted access to the site but only allowed to access information submitted by account associated with the password.

The server 16 also maintains the global address book for downloading of the address book to the producers, e.g., 12. This global book is updated automatically as new affiliates, clients, and producers register with the delivery server 16. The server 16 provides an on-line registration capability for affiliates or clients accessing the server web-site described above.

A clean-up or archiving process (not shown) may be added as a back office operation to allow an operator to delete or archive any envelopes, e.g., 20, that have expired according to the expiration date for the envelope. The clean-up process could also delete any media files that are not identified in any envelopes, e.g., 20, on the server 16.

The server 16 can also run a fax agent (not shown). The mailman can monitor document files in received envelopes to determine if any document is marked with a fax attribute, and for any such document, forward it to a fax server such as Microsoft Exchange's fax service (not shown). The fax server then automatically faxes the document to the fax numbers requested in the envelope.

Referring now to FIG. 6, the client or affiliate workstation runs affiliate software including a polling agent 108 that automatically places a phone call to the delivery server 16 at intervals or specific times set by the delivery server 16 or upon receipt of a "tickle" or triggering communication received from the delivery server 16. The tickle takes place by the server 16 dialing the phone number for the affiliate or client 20 in order to cause one or two telephonic rings to take place on the modem of the affiliate or client 20 through the two-way POTs or ISBN communication line, e.g., 22 of FIG. 1. The affiliate or client modem (not shown) is set so that it will not answer with only two rings. A tickle monitor associated with the polling software 108, however, monitors the modem (through the Microsoft Telephone API (TAPI) facility) and recognizes the ringing or tickle, which causes the polling agent 108 to call the delivery server 16 (or any other alternative server (not shown) available to the affiliate or client), log-in to the server 16 (including by use of a unique and secure password), and pick-up any packages waiting at the server 16 (or alternative server, not shown) for delivery to the client or affiliate 20. In this regard, upon connecting to the server 16, the client or affiliate 20 exchanges any awaiting messages with the server 16 and, via its package list browser 109, checks its inbox 110 for any newly arrived messages or envelopes, 114, 116. Upon review of the newly received envelopes 114, 116 (including receipt of any such envelopes by satellite in the case of a satellite affiliate), the delivery agent (not shown) running in association with the browser 109 determines if any envelopes 114, 116 identify any packages or files that have not already been otherwise received by the client or affiliate 20 and stored on its hard disk 118. For any file not already present on the hard disk 118, the delivery agent requests and obtains an FTP transfer of the missing file from the server 16 to the client or affiliate hard disk 118 associated with the delivery agent. Upon automatic completion of these tasks and transfer of all envelopes and files addressed to the client or affiliate 20, the client or affiliate 20
hangs up automatically.

In this fashion, the server 16 accomplishes a combination push-pull of the package(s) for the client or affiliate 20. The `push` takes place by tickling the client or affiliate 20 to inform it that the server 16 has content to deliver to the client or affiliate 20. The client or affiliate 20 then responds to the push or tickle by calling into the server 16 to pull the content from the server 16. The push takes place at no economic cost to the system and method, and with minimal effort. The pull and delivery of intended content to the client or affiliate 20 then takes place at the expense of the single phone call to the client or the affiliate 20 (unless otherwise arranged by the system administrators or users), with no need for any permanent or dedicated two-way connection between the server 16 and client or affiliate 20, and with a relatively high degree of security.

Whenever the delivery agent determines that the contents of a given package (as identified in the envelope for the package) are completely received by the client or affiliate 20, the delivery agent causes the client or affiliate 20 to take two additional actions. First, the client or affiliate 20 sends an e-mail to the server 16 confirming the delivery of the package to the client or affiliate 20. Second, the delivery agent flags all received packages, along with the packages' respective home-HTML information (64 in FIG. 3), for display to a user through the browser interface 109 at the client or affiliate 20.

The browser interface 109 on the client or affiliate 20 is based on the Microsoft Internet Explorer. As explained in greater detail below, the browser 109 provides a package hierarchy, inbox, and trash bin, and utilizes HTML for its package lists, so that received media files can be conveniently previewed, auditioned, or played.

Each server 16, producer 12, and client or affiliate 14 maintain substantial database information in addition to that already identified above. The server 16 maintains its database information in Microsoft SQL running on the server 16. The producers 12 and clients and affiliates 14 maintain their database information in the standard Windows 95 or Windows NT registry provided by the operating system on the clients and affiliates 14.

The data maintained in the server SQL database is as follows:

Producer Account 1. Unique producer reference name 2. Contact person at producer 3. Producer billing address 4. Producer fax telephone number 5. Producer password 6. Unique producer account number

Client (or Affiliate) Account 1. Unique client reference name 2. Contact person at client 3. Client shipping address 4. Client fax number 5. Client e-mail address 6. Client communication line types (satellite, ISDN, POTs, Drop-ship) 7. Delivery visibility: package type filtering (any package, audio-spot-packages, video-spot-packages, etc.) This field hides clients from producers that do not generate packages of the type for the hidden clients. 8. Polling schedule (Note that the Global Address Book is derived from this client-account information.)

Value added service options (manual addressing, media previewing, quality assurance, etc.) 9. File list (filename and attributes) 10. Address list (unique client identifications) Note: Items 5 8 and 10 immediately above are not forwarded to the clients or affiliates. File attributes include date, size, CRC, unique reference name, and home-HTML.

Client Tickle Record 1. Unique reference name 2. Tickle status (0=none, 1=to be tickled, 2=tickle succeeded, 3=tickle failed) 3. Timestamp of last tickle status 4. Status summary of last dial-in (e-mailed from client) 5. Timestamp of last connection

Log Message 1. Unique client reference name 2. Log timestamp 3. Level (log, warning, error, fatal) 4. Generation application 5. Message

The database maintained by the client (affiliate) registry is as follows:

Configuration 1. Dial schedule (e-mailed to client from server) 2. Line types: satellite, ISDN, POTs

Package 1. Envelope (see above) A. Unique package identification B. Package subject (display name) C. Package type (generic, audio spot, video spot, etc.) D. Producer name E. File list (filename & attributes) 2. Status flags (envelope received, media files in progress, media files complete, package viewed, package deleted) 3. Display folder (default inbox, recycle folder schedules it for deletion)

Folders 1. Name (e.g., "Inbox" and "Inbox.dagger.Media World")

Phone Book 1. Primary server: phone number & line type (ISDNIPOTs) 2. Backup server: phone number & line type (ISDN/POTs)

The data maintained in the producer registry is as follows:

Configuration 1. Line types: satellite, ISDN, POTs

Package 1. Envelope (see above) A. Unique package identification B. Package subject (display name) C. Package type (generic, audio spot, video spot, etc.) D. Producer name E. File list (filename & attributes) F. Address list 2. Status flags (envelope received, media files in progress, media files complete, package viewed, package deleted) 3. Display folder (default inbox, recycle folder schedules it for deletion)

Folders 1. Name (e.g., "Inbox" and "Inbox.dagger.Media World")

Phone Book 1. Primary server: phone number & line type (ISDN/POTs) 2. Alternate server: phone number & line type (ISDN/POTs)

Referring again to FIG. 6, the delivery server 16 is able to generate a comprehensive list of packages, e.g., 76 that are to be manually shipped to clients or affiliates 20 that have not or cannot receive the package by satellite or by terrestrial (ISDN or POTs) connections. The delivery server 16 maintains an outbox 106 for the manual delivery service. The manual delivery service can log onto the server 16 to procure the list of packages, e.g., 76, for manual delivery and associated files for physical duplication of the file(s) for each package onto a physical media, such as a tape 116 or CD (not shown), for ground delivery 120 or other manual delivery such as by a combination of air express and ground delivery 120.

The mailman 83 and traffic cop 84 applications, as shown in FIG. 6, operate according the flow chart shown in FIG. 7. These two applications 83, 84 monitor their respective inboxes 90, 100 to receive and process envelopes, e.g., 60, and status confirmations, e.g., 102.

Referring now to FIG. 8, the delivery server 16 also runs a core mailroom application shown in FIG. 8. The mailroom application consists of the processes shown in FIG. 8 along with the sub-processes (validate, addressing, and verify) shown in FIG. 9, and the sub-processes (satellite, forwarding, and confirmation) shown in FIG. 10. In essence, the mailroom application processes and forwards, as shown in FIG. 6, the envelopes, e.g., 60, and confirmations, e.g., 102, saved into the central database 98 by the mailman 83 and traffic cop 84 applications of FIG. 7. The mailroom thus decides when, where, and how to forward packages, e.g., 76, to clients or affiliates, e.g., 20, as shown in FIG. 6.

The tickle or tickler application referenced in FIG. 10, and noted above, is a self-running application on the delivery server 16. When the delivery server 16 requires that a package must be picked up immediately by a client or affiliate 20, the mailroom agent on the server 16 submits a request to the tickler application to dial out and ring the specified client or affiliate. As also noted above, the client's tickle monitor detects the ring and dials out to the server 16 (or to an alternate server (not shown) which may be a local, Internet ISP, or other server of packages for the client) so that the client may pull its packages from the server as described above

With reference to FIG. 6, the affiliate or client 20 also runs a warehouse manager application (not shown) also noted above. The warehouse manager is the high-level communications server for the user interface of each client or affiliate 20. The warehouse manager manipulates the client database described above as directed by the client or affiliate through its graphical user interface (the "browser"). The warehouse manager thus maintains the package hierarchy, performs garbage collection and deletion of obsolete files, maintains the activity and error log, and notifies the client or affiliate browser of newly arrived packages.

Communications between the warehouse manager and client or affiliate graphical user interface take place through standard interprocess communications protocols such as TCP/IP and HTTP. The warehouse manager also runs a garbage collection process, which (i) removes expired packages after their respective kill or expiration dates, and (ii) purges the oldest media in the recycle bin, whether it has expired or not, as disk space lowers past a threshold.

The mailroom agent noted above is responsible for fetching packages using e-mail and FTP, tracking incomplete packages, and then adding the completed packages to the warehouse manager.

Still referring to FIG. 6, each satellite affiliate 20 also runs a satellite agent application, called a BFTP receiver. This application saves all files that it receives from the satellite broadcast via the BFTP protocol explained below.

The producer and client user interfaces are similar. For example, with reference to FIG. 11, the producer interface (not shown) appears much like the client interface 122 but with the toolbar 103 of FIG. 12 rather than the client or affiliate toolbar 105 shown in FIG. 11. The producer interface has:

1. a tree structure to organize folders and packages;

2. an "outbox" folder containing outgoing packages (see outbox 80 in FIG. 4);

3. capability to create, delete, rename, and remove folders;

4. capability to delete and move packages;

5. a search and sort utility for packages;

6. a tool for previewing or auditioning media files (e.g., for playing an audio file through an audio card in the producer workstation);

7. an archiving agent that archives packages after their associated expiration dates;

8. a transaction log and word processing tool for viewing and printing the log; and

9. compatibility with Microsoft Explorer (preferably version 4.0 or higher).

As shown in FIG. 13, the producer and client interface, e.g., 122 of FIG. 11, occupy the central area 123 of the Microsoft Explorer browser interface on the producer. The central area 123 actually consists of three sub-areas: an HTML helper icon or toolbar sub-area 124, and tree sub-area 126, and a content sub-area 128.

With reference to FIG. 12, the initial applications located in the helper sub-area 124 for the producer interface are: 1. Packager: provides the forms and facilities for creating a package prior to sending it. The following sections are included in the form: packaging slip with purchase order number, package identification, producer name, subject of the package, and description of its contents; content listing of file types, ISCI codes, and descriptions; address listing of the clients or affiliates to whom the package is to be delivered, chosen from a global or private address list (which the producer may create or edit); the address listing may be left empty for later entry; traffic instructions in the form of an imported fax image or text typed into the form; delivery options; and an HTML page generator, which is viewed by the client or affiliate upon receipt and opening of the package; can include logos, comments, or any other form of information that can be communicated to the client or affiliate by this HTML generator. 2. Address book manager: provides the capability to view and edit the private address list and submit new addresses to the global list maintained by the delivery server; 3. Tracking: provides the capability to connect to the delivery server and log into and view the web-site on the server as described above; the producer can thus inspect confirmation of delivery information maintained by the server with timestamps based on purchase order numbers and package tracking numbers; 4. Search: a search and report agent that locates folders, packages, or items with a package based on filtering criteria; for example, the producer may procure a listing of packages that were created after a certain date or find an audio file with a particular ISCI code. 5. Log: provides a log of all major transactions performed by the producer; the user may display and print a log filtered according to filters selected by the operator; and the operator may purge or archive the log; 6. Options: provides configuration election tools; for example, the operator may change the dialing properties or account settings for accessing the delivery server; and 7. Audio studio: a utility for playing, editing, recording, or viewing graphical display of, audio files; displays cut description, ISCI code of the cut, and duration of the cut. Preferably, this utility can convert WAV files to MPEG Layer II files by means of a software encoder on the producer. 8. Opional video studio: a utility for playing, editing, or recording video files.

Referring now to FIGS. 13 and 15, the tree control area 126 for the producer and client or affiliate user interface contains information generally of the type shown in FIG. 15. More particularly, this basic tree structure contains: 1. an inbox for any packages on the workstation; 2. "trash" folders to move packages and media the user wishes to delete; and 3. a "saved" folder where the user may reorganize the packages.

The tree control provides the following functionality: 1. all packages are displayed in the producer or client or affiliate folder, and they are sorted; 2. items within a package cannot be deleted; 3. the user can move packages and media within a package from folder to folder by drag and drop; 4. clicking on an audio media file within a package triggers an audio player to play the audio through a sound card, such as Soundblaster card or professional quality Digigram card; 5. if the traffic instruction is a fax image, clicking on it triggers an image viewer to display the fax image; 6. a package can have any type of media within it; and 7. if a package is deleted form the "trash" folder, it is discarded from the workstation system.

The content area 128 shows detailed information about a selected tree branch in HTML form, as noted above. With regard to the example of shown in FIG. 15: 1. if "home" is selected or clicked by the operator, the HTML display in the content area
128 show pertinent company information, such as the company logo for the operator of the particular producer workstation; and 2. if a particular package is selected, the displayed HTML shows the detailed description of the package and all of its contents;

Referring now to the affiliate or client user interface shown in FIG. 11, this interface 122 appears when the affiliate or client application software is first booted or loaded by the operator of the affiliate or client workstation. This screen has four areas: toolbar 105, search criteria 130, media list area 132, and audio player area 134. The last three of these areas all appear whenever the operator selects the inbox button on the toolbar 105.

Alternatively, the audio player may be deleted from the user interface of FIG. 11 so that it is launched in its own, separate window or screen. In this fashion, any of a variety of generic audio players may be utilized without customization for insertion into the interface screen of FIG. 11.

Referring again to the producer toolbar shown in FIG. 12, this toolbar 103 includes packager 136 and tracking 138 buttons not present in the client or affiliate toolbar 105 of FIG. 11. The packager button 136 launches that packaging wizard (not shown), and the tracking button 138 causes the delivery status of a package to be displayed in the content area 128 of the producer interface as shown in FIG. 13.

Both the producer interface and the affiliate or client interface have the following features: 1. a new mail indicator provided by an animated inbox icon (content appearing to fall into the inbox); and 2. an error indicator provided by the logs button turning red when repeated attempts to connect to the delivery server 16 have failed.

Referring again to FIG. 11, the search area 130 of the affiliate or client interface allows the operator to type in a search term and display, in the media listing area 132 a listing of all media files containing the search term in their respective titles, identifications of producer or advertiser, or ISCI codes. Through this search area 130, the operator may also choose to display certain types of media files, such as audio spots, new spots, spots that have arrived in the last 24 hours or the last week, or spots that have been sent to the trash bin (which spots can then be recovered if still in the bin).

The search area 130 also contains an advanced button to allow the user to display advanced search options, such as a choice of the types of the content that should be listed. Thus, although the applicant's default button arrangement allows the user to view a list of audio spots only, the advanced buttons allow the user to display traffic instruction or other types of media file listings.

The media listing 132 depends on the options elected in the search area 130. For each item of audio content, e.g., 139, displayed, the list sets forth the title 140, advertiser 142, ISCI code 144, and arrival time 146. These items are displayed by title by default, but the user may sort these columns by clicking on the respective column header, e.g., 140, 142, 144, 146.

To the left of each item of content is an icon reflecting the type of content within the item (e.g., a CD for audio, paper for traffic instructions, etc.). New items not yet opened are in bold, and locked items also appear with a small padlock icon. A locked item is a media file that the affiliate or client user wishes to keep without the client's or affiliate's warehouse manager removing it to make space for new content. The client or affiliate can only lock files amounting to a total of ten percent of the client's or affiliate's entire hard disk space.

As with the tree control explained above for the producer interface, the user can load and play an audio item, for example, by double clicking on it. Right clicking on an item will provide a pop-up menu with options such as opening, locking, or deleting the item, viewing properties for the item (including its title, description, ISCII code, and advertiser), showing the package in which the item arrived, etc.

The digital audio player 134 provides standard MPEG layer II record and playback features. Previous and next buttons may also be added for the audio player 135, and the player may include an additional button 135 to allow trim points to be manually programmed and saved with the audio spot.

Referring now to FIG. 14, the inbox interface for a client or affiliate includes a toolbar area 150, an inbox area 152, a producer logo area 154 (when a particular package is selected), and a package media content area 156. The inbox area 152
thus lists all packages in the inbox for the client or affiliate, and the producer logo area 154 depicts the logo of the producer of the particular package selected in the inbox area 152. The media content area 156 shows the media files with associated icons depicting the nature of the content in the package, and the user may double click on each such media file or icon to view or play the associated file, depending on the nature of its contents.

Referring now to FIG. 16, the web-site hosted by the media server 16 provides a package tracking interface 160 when a user dials in and logs onto the web-site or otherwise accesses the web-site interface through the Internet. After the user enters its account name and password, the package tracking interface presents a listing 162 of all packages submitted to the web-site by that user. The package tracking interface also provides filtering and sorting options. The listing 162 preferably includes the package identification 164, the user's purchase order number for the package 166, the status of the package (delivered or awaiting delivery) 168, and the transaction time for any completed delivery 170.

Referring now to FIG. 17, if the user or operator accessing the web-site on the server 16 then clicks on a given package identification in the listing 162 on the package tracking interface 160 as shown in FIG. 16, the package detail report interface 172 appears for the particular package selected by the operator or user. This report 172 provides additional information about the status of a given package, such as affiliate confirmation details 174 the contents of the package 176.

Envelopes and Confirmations:

A With reference again to FIGS. 1 6, envelopes generated within the applicants preferred system 10 are named: ENV.pkgid.TXT, where "pkgid" is a package identification that uniquely identifies a package across all producers. Pkgid is a long decimal value generated by the producer's package Wizard. The high-word of the package identifier is the unique producer identification The low-word is a persistent incrementing counter (wraps after 32K packages).

The file format for envelopes is as follows:

ENVELOPE

ID: #pkgid

DATE: yy/mm/dd hh:mm:ss

ACCT: "account"

AD: "advertiser"

PO: "workorder"

SUBJ: "title"

DESC: "description"

FOLDER: "folder"

PRIO: [BEST/LOCALX/EXPRESS2/EXPRESS4/LOCAL/OVERNIGHT/TWODAY]

LIFE: showtime,killdate

FILE: "filename" "title" "description" "iscii","advertiser",filesize, "yy/mm/dd hh:mm:ss"

ADDR: "account"[,"fullname", "address", "phone"]

Note:

The ENVELOPE tag must appear first in the envelope. All other tags may appear in any sequence. All tags are separated by CR and/or LF (ascii 13 or 10). All tags are separated from data fields by a colon and a space pair. All data parameters are comma separated. Any data parameter that includes commas or spaces will be enclosed in quotes. Required tags appear in bold. When not supplied, the default value (an empty string) is assumed. pkgid is package ID that uniquely identifies a package across all producers. It's a long decimal value generated by the producer's packager Wizard. The high-word of the package ID is the unique producer dax ID. The low-word is a persistent incrementing counter (wraps after 32K packages). account is the short login account name, e.g. KROQ. showtime and killdate are timestamps derived from the C library call time( ) representing the number of seconds elapsed since Jan. 1, 1970. A showtime values of 0 indicates pacakge is displayed immediately upon arrival. A killdate of 0 indicates package does not automatically expire. One FILE tag should exist for each file. The filesize field is in bytes. The file timestamp is the last modification date/time of the file. The filename is a long filename augmented as follows: media.TTTTTTTT-SSS.title.ext home.pkgid.html logo.daxid.title.ext where ext is the file type (audio files will be .S48, logo images will be .BMP or .GIF, etc.) where title.ext is the full filename as created or imported on the producer (pre-augmented) where TTTTTTTT is the 8-character hexidecimal modification timestamp of the file where SSS is the hexidecimal filesize in bytes where daxid is the unique producer dax ID. where pkgid is the unique package ID (in decimal) to which the HTML applies. One ADDR tag should exist for each recipient of the package. The account value represents the unique globally addressible account. If the recipient is from the private address book, full mailing information is provided with additional parameters. Special characters: CR/LF characters embedded within quoted data values are replaced with pipe character: | Envelope encoding: for the reasons of security and integrity, envelopes may be encoded with a proprietary encoding scheme specified later. The specification for confirmations sent within the system 10 are named as follows. CONFIRM.pkgid-account.TXT Note: pkgid is package ID that uniquely identifies a package across all producers. It is a long decimal value generated by the producer's packager Wizard. The high-word of the package ID is the unique producer dax ID. The low-word is a persistent incrementing counter (wraps after 32K packages). account is the short login account name of the confirming affiliate (not the producer of the package), e.g. KROQ. The file format for confirmations is as follows: CONFIRMATION ID: #pkgid ACCT: "account" DATE: yy/mm/dd hh:mm: ss Note: The above message is e-mailed by recipients (clients or affiliates) back to the delivery server mailman after the package has been completely fetched. The tags are described in the envelope specification. The date represents the local date/time the affiliate or client completed picking up the package. The account is that of the confirming affiliate or client (not the producer of the package). A package addressed to N online affiliates or clients causes N confirmation messages to be returned and processed by the mailman. BFTP:

The purpose of Broadcast File Transfer Protocol (BFTP) is to reliably transmit binary files over a one-way broadcast satellite network from an uplink server to one or more downlink clients. The BFTP protocol includes a means of group addressing such that the file will be received and stored only by those target sites (affiliates) included in an address list.

In order to address target sites, each site is provided a unique numeric identification. This identification is a 32-bit numeric value in the range 1 4,294,967,295 (providing over 4 million unique identifiers). 0 is reserved as a broadcast identification. Each affiliate identification is stored (in encoded format) in the affiliate registry and may be programmed through an affiliate configuration form.
