Abstract

There is provided a system, method and software application that receives a data stream via a data network such as the Internet. The received data is recorded in a data storage device. The system stores various transcoding algorithms for a variety of playback devices and transfer networks. The recorded data is then transcoded into a format compatible with other devices or data transfer constraints. A user can interface with the system to input information particular to the other devices and transfers. This information is stored by the system and used to determine the transcoding algorithm best suited to the needs of the user based on the user input.

Claims

1. A data recording apparatus comprising:

means for storing content information, when received, as data in a first digital format, and

means for transcoding the stored data to a second digital format, at least partially in an off-line mode, the second data format being different from the first data format.

2. The apparatus of claim 1, comprising means for storing the transcoded data.

3. The apparatus of claim 1, wherein the means for transcoding the stored data supports a multi-pass transcoding algorithm.

4. The apparatus of claim 1, comprising means for playing out the transcoded data.

5. The apparatus of claim 1, comprising a connection to interface to a network for enabling a transfer of the data.

6. The apparatus of claim 5, wherein the connection to the network supports downloading of transcoding software.

7. A data recording apparatus comprising:

at least one input;

a data processor;

a data storage device for storing content information, and a memory for storing code for at least one processing algorithm;

wherein the content information is received, as data in a first digital format, via the input and stored in the data storage device, the data is transcoded into a second format according to the at least one processing algorithm, the transcoding is done, at least partially, in an off-line mode and the second data format being different from the first data format.

8. The apparatus of claim 7, comprising a network connection for connecting to at least one of a home network and the Internet;

and

wherein the data is transferred via the network

9. The apparatus of claim 7, further comprising a user interface that enables the user to select an output data format for said transcoding.

10. The apparatus of claim 7, further comprising means for modifying transcoding software.

11. The apparatus of claim 7, wherein the data storage device comprises at least one of a hard disk drive, optical memory, and a solid state memory.

12. The apparatus of claim 7, wherein the transcoded data is stored in the storage device.

13. A software application (SW) for control of playback of content information, comprising:

a storage module enabling storage of the content information; and

a transcoding module to enable a transcoding of the stored content information in at least partially an off-line mode.

14. The SW of claim 13, comprising a second storage module to enable storage of the transcoded content information in the storage device.

15. The SW of claim 13, comprising a transfer module to enable a transfer of the content information via a network, the network being one of a home network and the Internet.

16. A method of enabling playback of content information, comprising:

receiving the content information in a datastream;

storing the received content information, and transcoding the stored content information in at least partially an off-line mode.

17. The method of claim 16, comprising:

determining a system requirement of playback equipment, and providing transcoding software application based on the system requirement.

18. The method of claim 17, comprising providing the transcoding software application automatically based on the determination.

19. The method of claim 17, wherein the transcoding software application is provided upon one of a request of a user and an automatically supplied request by equipment of the user related to the playback of content.

20. The method of claim 16, comprising at least one of storing the transcoded information, and transmitting the content information.
