Abstract

The recording of digital media according to one or more of playback device capabilities, network performance and user preference is disclosed. One embodiment provides a method for recording digital video comprising determining a first set of capabilities of a first networked playback device, receiving media in at least one of a first format and a first bit rate, and recording the media in at least one of a second format and a second bit rate according to the first set of capabilities. In this manner, playback considerations may be incorporated while the digital media is recorded, thus improving the playback of the digital media at a later time.

Claims

1. A method of recording digital video, the method comprising:

determining a first set of capabilities of a first networked playback device;

receiving media in at least one of a first format and a first bit rate; and

recording the media in at least one of a second format and a second bit rate according to the first set of capabilities.

2. The method of claim 1, wherein the first set of capabilities includes at least one of a supported media format, a supported bit rate, usage statistics, playback quality statistics, network connection performance, and hardware capabilities of the first networked playback device.

3. The method of claim 1, further comprising determining a second set of capabilities of a second networked playback device.

4. The method of claim 3, wherein the second set of capabilities includes at least one of supported media format, supported bit rate, usage statistics, playback quality statistics, network connection performance, and hardware capabilities of the second networked playback device.

5. The method of claim 3, further comprising recording the media in at least one of a second format and a second bit rate according to the first set of capabilities and the second set of capabilities.

6. The method of claim 5, wherein recording the media according to the first set of capabilities and the second set of capabilities includes selecting a commonly supported format or bit rate of the first and second playback devices.

7. The method of claim 5, further comprising:

selecting a preferred format or bit rate according to at least one of a user preference, playback device usage, and playback device capabilities of the first and second playback devices; and

recording the media according to the preferred format or bit rate.

8. The method of claim 5, further comprising recording the media using a scalable codec or multiple tuners according to playback device capabilities, to allow playback of multiple versions of the media.

9. A system, comprising:

a first playback device;

a client capabilities detection module configured to determine a first set of capabilities of the first playback device; and

a digital media recorder networked with the first playback device and in communication with the client capabilities detection module, the digital media recorder to receive media in at least one of a first format and a first bit rate, and to record the media in at least one of a second format and a second bit rate according to the first set of capabilities of the first networked playback device.

10. The system of claim 9, wherein the digital media recorder is a digital video recorder.

11. The system of claim 9, wherein the first set of capabilities includes at least one of a supported media format, a supported bit rate, usage statistics, playback quality statistics, network connection performance, and playback device hardware capabilities.

12. The system of claim 9, further comprising a second playback device, wherein the client capabilities detection module is configured to determine a second set of capabilities of the second playback device, wherein the second set of capabilities includes at least one of a supported media format, a supported bit rate, usage statistics, playback quality statistics, network connection performance, and playback device hardware capabilities.

13. The system of claim 12, wherein the digital media recorder is to record the media in at least one of a second format and a second bit rate according to the first set of capabilities and the second set of capabilities.

14. The system of claim 9, wherein the media is recorded according to a commonly supported format or bit rate of the first and second playback devices.

15. The system of claim 9, wherein the media is recorded according to a preferred format or bit rate, wherein the preferred format or bit rate is selected by at least one of a user preference, playback device usage, and playback device capabilities.

16. The system of claim 9, wherein the digital media recorder is configured to record the media with a scalable codec or with multiple tuners according to the first and second playback device capabilities, to allow playback of multiple versions of the media.

17. A computing device, comprising:

memory;

a processor; and

instructions stored in memory and executable by the processor to determine capabilities of at least one networked playback device, to receive media in at least one of a first format and a first bit rate, and to record the media in at least one of a second format and a second bit rate according to the capabilities of the at least one networked playback device, wherein the capabilities include at least one of a supported media format, a supported bit rate, usage statistics, buffer fullness, network connection performance, and hardware capabilities of the networked playback device.

18. The computing device of claim 17, wherein the media is recorded according to a commonly supported format or bit rate of a plurality of networked playback devices.

19. The computing device of claim 17, further comprising instructions to select a preferred format or bit rate according to at least one of a user preference, playback device usage, and playback device capabilities of a plurality of playback devices, and instructions to record the media according to the preferred format or bit rate.

20. The computing device of claim 17, further comprising instructions to record the media using a scalable codec or multiple tuners according to playback device capabilities, to allow playback of multiple versions of the media.
