Abstract

Various apparatus, systems, and articles including a machine-accessible medium, along with methods of processing and transferring audio-video content, are disclosed. The apparatus may include a resampler to receive and transform an original data stream into a sampled data stream; a first encoder to produce a first playback data stream by encoding the sampled data stream; and a second encoder to produce a second playback data stream by encoding the original data stream. Alternatively, the apparatus may include an encoder to receive and encode the original data stream into a second playback data stream; a memory to store the second playback data stream; a decoder to provide a final playback data stream by receiving and decoding the second playback data stream; and a resampler to receive and transform the final playback data stream into a sampled data stream, which the encoder receives and encodes into a first playback data stream.

Claims

1. An apparatus, comprising:

an encoder to receive and encode an original data stream into a second playback data stream;

a memory capable receiving and storing the second playback data stream;

a decoder to receive and decode the second playback data stream into a final playback data stream for playback to a viewer;

a resampler to receive and transform the final playback data stream into a sampled data stream, wherein the encoder is to receive and encode the sampled data stream into a first playback data stream; and

at least one of a disk drive internal to a portable electronic device and removable media inserted into the portable electronic device to replay the first playback data stream.

2. The apparatus of claim 1, further comprising:

a digital data receiver capable of receiving and transforming the final playback data stream into a signal to be received by a television.

3. The apparatus of claim 1, further comprising:

a data display generator to generate a user interface display including data associated with the first and second playback data streams.

4. A method, comprising:

receiving an original data stream;

encoding, using an encoder, the original data stream into a second playback data stream;

decoding the second playback data stream to provide a final playback data stream;

transforming the final playback data stream into a sampled data stream;

encoding, using the encoder, the sampled data stream to produce a first playback data stream; and

storing the first playback data stream on at least one of a disk drive internal to a portable electronic device and removable media inserted into the portable electronic device to replay the first playback data stream.

5. The method of claim 4, further comprising:

storing the second playback data stream before transforming the final playback data stream into a sampled data stream.

6. The method of claim 4, further comprising:

storing the first playback data stream; and

transmitting the first playback data stream to a data processing apparatus selected from the group consisting of a laptop computer, a palmtop computer, a personal digital assistant, a cellular telephone, a web tablet, and a dedicated audio-video playback device.

7. An apparatus, comprising:

an encoder to receive and encode an original data stream into a second playback data stream;

a decoder to receive the second playback data stream from a second memory and to decode the second playback data stream into a final playback data stream; and

a resampler to receive and sample the final playback data stream to provide a sampled data stream, wherein the encoder is to receive and encode the sampled data stream into a first playback data stream, and wherein the final playback data stream is for playback to a viewer.

8. The apparatus of claim 7, further comprising:

a digital data source to transmit the original data stream to the encoder.

9. The apparatus of claim 7, further comprising:

a first memory to store the first playback data stream.

10. The apparatus of claim 7, further comprising:

the second memory to store the second playback data stream.

11. The apparatus of claim 7, further comprising:

a digital data receiver to receive and transform the final playback data stream into a television signal.

12. The apparatus of claim 7, further comprising:

a data display generator to generate a user interface display including data associated with the first playback data stream.

13. A method, comprising:

encoding, using an encoder, an original data stream into a second playback data stream;

decoding the second playback data stream to provide a final playback data stream;

sampling the final playback data stream to provide a sampled data stream; and

encoding, using the encoder, the sampled data stream to provide a first playback data stream to be played back by a portable electronic data processing device.

14. The method of claim 13, further comprising:

storing the first and second playback data streams.

15. The method of claim 13, further comprising:

transmitting the first playback data stream to a data processing apparatus selected from a group consisting of a laptop computer, a palmtop computer, a personal digital assistant, a cellular telephone, a web tablet, or a dedicated audio-video playback device.

16. The method of claim 13, further comprising:

transmitting the final playback data stream to a television.

17. The method of claim 13, further comprising:

receiving an Advanced Television Systems Committee (ATSC) television signal; and

transforming the ATSC signal into the original data stream.

18. The method of claim 13, further comprising:

receiving a Phase Alternation by Line (PAL) television signal; and

transforming the PAL signal into the original data stream.

19. An article comprising a computer-readable medium having instructions stored thereon, wherein the instructions, when executed by a computer, result in the computer performing:

encoding, using an encoder, an original data stream into a second playback data stream;

decoding the second playback data stream to provide a final playback data stream;

sampling the final playback data stream to provide a sampled data stream; and

encoding, using the encoder, the sampled data stream to provide a first playback data stream to be played back by a portable electronic data processing device.

20. The article of claim 19, wherein the instructions, when executed by the computer, result in the computer performing:

transmitting the first playback data stream to a data processing apparatus; and

transmitting meta-data associated with the first playback data stream to the data processing apparatus.

21. The article of claim 19, wherein the instructions, when executed by the computer, result in the computer performing:

transmitting the first playback data stream to a data processing apparatus; and

transmitting an executable playback program associated with the first playback data stream to the data processing apparatus.

22. The article of claim 19, wherein the instructions, when executed by the computer, result in the computer performing:

transmitting the final playback data stream to a television.
