1. (WO1995004431) SYSTEM AND METHOD FOR STORING AND FORWARDING AUDIO AND/OR VISUAL INFORMATION ON DEMAND
Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

WE CLAIM:

1. A system for storing and forwarding audio/video signals on demand, comprising:
an encoder for receiving at least one of said audio/video signals, digitizing said audio/video signals, and compressing said digitized signals into a data stream;
a first processing system for receiving said data stream from said encoder, further compressing said data stream, storing said data stream in a storage media, and later transmitting said data stream from storage;
a transmitting system for receiving said data stream from said processing system and transmitting same to a location remote from said processing system;
a second processing system including a microprocessor for receiving said data stream from said transmitting system, processing said data stream, storing said data stream in a storage media, and, upon receipt of a request for replay of said audio/video signal later transmitting a copy of said data stream from such storage media after decompressing said copy of said data stream;
a decoder for receiving said data stream copy from said storage media, further decompressing said data stream and transforming said decompressed data stream into an analog signal for transmission to at least one television set for replay.

2. The system for storing and forwarding audio/video signals on demand of Claim l, wherein said storage media is random access mass storage media.

3. The system for storing and forwarding audio/video signals on demand of Claim 1, wherein said transmission by said second processing system is synchronous replay to said decoder.

4. The system for storing and forwarding audio/video signals on demand of Claim 1, wherein said request for replay of said analog signal is from another processing system.

5. The system for storing and forwarding audio/video signals on demand of Claim 1, wherein said request for replay of said analog signal is from another program running simultaneously on said second processing system.

6. The system for storing and forwarding audio/video signals on demand of Claim 1, wherein said decompressing by said second processing system is rebuilding of said data stream.

7. The system for storing and forwarding audio/video signals on demand of Claim 1, wherein said compressing by said first processing system is stripping off network overhead from said data stream.

8. The system for storing and forwarding audio/video signals on demand of Claim 7, wherein said network overhead includes forward error correction and addressing information.

9. The system for storing and forwarding audio/video signals on demand of Claim 1, wherein said second processing system further comprises a communications board for enabling direct data transfer from said storage media to said decoder.

10. The system for storing and forwarding audio/video signals on demand of Claim 9, wherein said communications board bears a data queue controller for managing input, output and system channels of said communications board.

11. The system for storing and forwarding audio/video signals on demand of Claim 10, wherein said data queue controller ensures buffers in all output channels of said communications board are timely filled during transmission to prevent under- or over-filling of a channel.

12. The system for storing and forwarding audio/video signals on demand of Claim 1, wherein said first processing system further comprises a communications board for enabling direct data transfer from said encoder to said storage media.

13. The system for storing and forwarding audio/video signals on demand of Claim 12, wherein said communications board bears a data queue controller for managing input, output and system channels of said communications board.

14. The system for storing and forwarding audio/video signals on demand of Claim 1, wherein said first processing system further includes a microprocessor.
