Abstract

A data file delivery system is provided having, at a head end, a production subsystem which communicates with a delivery subsystem via a local area network, ISDN connection, and the like. The delivery subsystem communicates with an affiliate subsystem, at a tail end, via a satellite link, ISDN link and the like. The production subsystem enables a producer to create audio events which represent sequences of audio which are played to completion before another audio event occurs. Audio events are stored as audio files. Each audio event may include one or more of an audio sequence, text information, delivery instructions, and an attribute list having contact closure information and the like. Optionally, multiple audio events may be assembled at the production subsystem to form a play list. The audio files are transferred to the delivery subsystem. The delivery subsystem places the audio files in delivery envelopes and transmits the envelopes to the affiliate terminals. In addition, the delivery subsystem may transmit live audio and related contact closure information to the affiliate terminals. The affiliate terminal may be located at a user site. The affiliate terminals may store these events on the hard drive, play the events in real time or pass events to other affiliate terminals. The affiliate terminal may later play stored audio events.

Claims

1. An improved method of transmitting at least audio information from production systems to one or more among a predetermined group of tail end users distal from the production systems, the improved method comprising the steps of

a. receiving at least a first audio signal on a first production system and at least a second audio signal on a second production system;

b. digitally encoding the first and second audio signals with a lossy compression algorithm to yield respective first and second lossy encoded files of lossy audio information;

c. predetermining a first group of tail end user apparatus for use of the first lossy encoded file and a second group of tail end user apparatus for use of the second lossy encoded file;

d. transmitting the lossy encoded files from the first and second production systems to a hub for automatic selective forwarding of the first and second lossy encoded files by the hub to the first and second groups of tail end user apparatus respectively; and

e. receiving, decoding, and playback broadcasting of the first and second lossy encoded files respectively on the first and second groups of tail end user apparatus, said decoding using a decoding algorithm for decoding of the lossy encoded file encoded with the lossy encoding algorithm.

2. The improved method of claim 1 wherein:

(1) the transmission step (d) takes place without further lossy compression of the lossy audio information in the lossy encoded file;

(2) the transmission step (d) includes transmission of a live encoded audio data stream by automatic multiplexing and transmitting the audio data stream with the lossy encoded file; and

(3) the receiving step (e) includes automatically demultiplexing of the received multiplexed audio data stream and lossy encoded file, and live decoding and use of the audio data stream by the tail end user apparatus.

3. The improved method of claim 1 also including in step (e):

playing the decoded file and automatically cross-fading the playback of the decoded file with the playback of a second audio file on the tail end user apparatus.

4. The improved method of claim 2 also including in step (e):

playing the decoded file and automatically cross-fading the playback of the decoded file with the playback of a second audio file on the tail end user apparatus.

5. The improved method of claim 1 wherein transmitting step (d) includes transmitting a command in connection with the lossy encoded file, and receiving step (e) includes automatic activation and use of the lossy encoded file according to the command.

6. The improved method of claim 2 wherein transmitting step (d) includes transmitting a command in connection with the lossy encoded file, and receiving step (e) includes automatic activation and use of the lossy encoded file according to the command.

7. The improved method of claim 3 wherein transmitting step (d) includes transmitting a command in connection with the lossy encoded file, and receiving step (e) includes automatic activation and use of the lossy encoded file according to the command.

8. The improved method of claim 4 wherein transmitting step (d) includes transmitting contract closure information in connection with the lossy encoded file, and receiving step (e) includes automatic activation of demand for use of the lossy encoded file according to the instructions embodied in the contact closure information.

9. The improved method of claim 1 wherein the transmitting step (d) includes pre-determination of whether to transmit through an extraterrestrial satlellite or other link and then transmitting through the determined link.

10. The improved method of claim 2 wherein the transmitting step (d) includes pre-determination of whether to transmit through an extraterrestrial satlellite or other link and then transmitting through the determined link.

11. The improved method of claim 3 wherein the transmitting step (d) includes pre-determination of whether to transmit through an extraterrestrial satlellite or other link and then transmitting through the determined link.

12. The improved method of claim 4 wherein the transmitting step (d) includes pre-determination of whether to transmit through an extraterrestrial satlellite or other link and then transmitting through the determined link.

13. The improved method of claim 5 wherein the transmitting step (d) includes pre-determination of whether to transmit through an extraterrestrial satlellite or other link and then transmitting through the determined link.

14. The improved method of claim 6 wherein the transmitting step (d) includes pre determination of whether to transmit through an extraterrestrial satlellite or other link and then transmitting through the determined link.

15. The improved method of claim 7 wherein the transmitting step (d) includes pre determination of whether to transmit through an extraterrestrial satlellite or other link and then transmitting through the determined link.

16. The improved method of claim 8 wherein the transmitting step (d) includes pre-determination of whether to transmit through an extraterrestrial satlellite or other link and then transmitting through the determined link.

17. The improved method of claim 1 wherein the transmitting step (d) includes predetermined transmission through an extraterrestrial satellite.

18. The improved method of claim 2 wherein the transmitting step (d) includes predetermined transmission through an extraterrestrial satellite.

19. The improved method of claim 5 wherein the transmitting step (d) includes predetermined transmission through an extraterrestrial satellite.

20. The improved method of claim 8 wherein the transmitting step (d) includes predetermined transmission through an extraterrestrial satellite.
