Abstract

According to one embodiment, a system is disclosed. The system includes a transmission device that converts a transport stream in to a transport stream file (TSF), a transmission medium coupled to the transmission device and a set top appliance, coupled to the transmission medium that receives the TSF.

Claims

1. A system comprising:

a transmission device having;

a transport stream file (TSF) generator to convert a transport stream of audio/video data in to a TSF including the audio/video data;

a file disk to store the TSF after it is generated by the TSF generator; and

an encode module to apply Forward Error Correction to the TSF to identify errors arising during transmission of the TSF and to encode the TSF for the transmission;

a transmission medium coupled to the transmission device to transmit the TSF; and

a set top appliance, coupled to the transmission medium, to receive the TSF.

2. The system of claim 1 wherein the transmission device further comprises:

a video encoder to encode video bit streams received at the transmission device;

an audio encoder to encode that encodes audio bit streams received at the transmission device; and

a first multiplexer, coupled to the audio encoder and the video encoder, to combine the encoded audio and video bit streams to form a transport stream to transmit to the TSP generator for conversion.

3. The system of claim 2 wherein the transmission device further comprises:

a data insertion module coupled to the encode module;

second multiplexer coupled to the data insertion module;

a modulator coupled to the second multiplexer; and

a transmitter coupled to the modulator.

4. The system of claim 3 wherein the encode module uses carouseling to encode the TSF.

5. The system of claim 3 wherein the set top appliance comprises:

a receiver;

a demodulator coupled to the receiver;

a de-multiplexer, coupled to the demodulator;

a data extraction module coupled to the de-multiplexer;

a decode module coupled to the data extraction module; and

data storage coupled to the decode module.

6. The system of claim 1 wherein the transmission medium is a satellite transmission.

7. The system of claim 1 wherein the transmission medium is a terrestrial broadcast.

8. The system of claim 1 wherein the transmission medium is the Internet.

9. A transmission device comprising:

a video encoder to encode video bit streams received at the transmission device;

an audio encoder to encode audio bit streams received at the transmission device;

a first multiplexer, coupled to the audio encoder and the video encoder, to combine the encoded audio and video bit streams to form a transport stream; and

a transport stream file (TSF) generator, coupled to the first multiplexer, to convert the transport stream into a TSF including the audio/video data transport stream;

a file disk to store the TSF after it is generated by the TSF generator; and

an encode module to apply Forward Error Correction to the TSF to identify errors arising during transmission of the TSF and to encode the TSF for the transmission.

10. The transmission device of claim 9 further comprising:

a data insertion module coupled to the encode module;

a second multiplexer coupled to the data insertion module;

a modulator coupled to the second multiplexer; and

a transmitter coupled to the modulator.

11. A method comprising:

encoding audio and video bit streams at a transmission device;

combining the audio and video bit streams to form a transport stream;

converting the transport stream to a transport stream file (TSF) including the audio/video data transport stream;

storing the TSF after it is converted from the transport stream; and

applying Forward Error Correction to the TSF to identify errors arising during a transmission of the TSF.

12. The method of claim 11 further comprising:

encoding the TSF for transport;

multiplexing the TSF;

modulating the TSF; and

transmitting the TSF.

13. The method of claim 12 further comprising:

receiving the TSF at a set top appliance;

demodulating the TSF;

decoding the TSF; and

storing the TSF.

14. An article of manufacture including one or more computer readable media that embody a program of instructions wherein the program of instructions, when executed by a processing unit, causes the processing unit to:

encode audio and video bit streams at a transmission device;

combine the audio and video bit streams to form a transport stream; and

convert the transport stream to a transport stream file (TSF) including the audio/video data transport stream;

store the TSF after it is converted from the transport stream; and

apply Forward Error Correction to the TSF to identify errors arising during a transmission of the TSF.

15. The article of manufacture of claim 14 wherein the program of instructions, when executed by a processing unit, further causes the processing unit to

encode the TSF for transport;

multiplex the TSF;

modulate the TSF; and

transmit the TSF.
