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 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.

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

a video encoder that encodes video bit streams received at the transmission device;

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

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

a TSF generator, coupled to the first multiplexer, that converts the transport stream into the TSF.

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

an encode module that encodes the TSF for transport;

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.

4. The system of claim 3 wherein the encode module uses forward error correction (FEC) and carousel ling 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 that encodes that encodes video bit streams received at the transmission device;

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

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

a transport stream file (TSF) generator, coupled to the first multiplexer, that converts the transport stream into the TSF.

10. The transmission device of claim 9 further comprising:

an encode module that encodes the TSF;

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; and

converting the transport stream to a transport stream file (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:

demodulating the TSF;

decoding the TSF; and

storing the TSF.

14. A method comprising:

receiving a transport stream file (TSF) at a set top appliance via a transmission medium; and

storing the TSF at the set top appliance.

15. The method of claim 14 further comprising:

demodulating the TSF;

de-multiplexing the TSF; and

decoding the TSF;

16. 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).

17. The article of manufacture of claim 16 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.
