Abstract

In one embodiment, a system to manage video content comprises an index file management module comprising logic to, generate an index file to describe content in an associated video file, store the index file for a video file in a first memory location, separate from a second memory location in which the video file is stored, receive, from a requesting entity, a request for access to the index file, in response to the request, download the index file to the requesting entity, and download the video file to the requesting entity.

Claims

1. A method to manage video content, comprising:

generating an index file to describe content in an associated video file;

storing the index file for a video file in a first memory location, separate from a second memory location in which the video file is stored;

receiving, from a requesting entity, a request for access to the index file;

in response to the request, downloading the index file to the requesting entity; and

downloading the video file to the requesting entity.

2. The method of claim 1, wherein generating an index file to describe content in an associated video file comprises:

scanning the associated video file; and

generating a video index file that indicates at least one frame boundary between frames in the index file.

3. The method of claim 1, storing the index file for a video file in a first memory location, separate from a second memory location in which the video file is stored comprises storing the index file in a cache memory module.

4. The method of claim 1, wherein:

the request for access to the index file is received via a first communication channel;

the index file is transmitted to the requesting entity via the first communication channel; and

the video file is transmitted to the requesting entity via a second communication channel.

5. The method of claim 1, further comprising:

receiving the video index file in a video display system associated with the requesting entity; and

storing the video index file in a memory module associated with the video display system.

6. The method of claim 5, further comprising:

receiving at least a portion of the video file in the video display system; and

storing at least a portion of the video file in a memory module associated with the video display system.

7. The method of claim 6, further comprising:

synchronizing the video index file with the at least a portion of the video file received in the video display system.

8. The method of claim 8, further comprising displaying the at least a portion of the video file received in the video display system.

9. A method comprising:

generating, in a video display system, a request for a video file;

generating a request for an index file that describes content associated with the video file;

transmitting the request for an index file to a distributor;

receiving, in response to the request, the index file that describes content in an associated video file;

storing the index file for a video file in a first memory location;

transmitting the request for the video file to the distributor;

receiving at least a portion of the video file in the video display system; and

storing at least a portion of the video file in a second memory location associated with the video display system.

10. The method of claim 9, wherein the request for an index file is transmitted to the distributor via a first communication channel and the request for the video file is transmitted to the distributor via a second communication channel, different from the first communication channel.

11. The method of claim 9, further comprising:

synchronizing the video index file with the at least a portion of the video file received in the video display system.

12. The method of claim 11, further comprising displaying the at least a portion of the video file received in the video display system.

13. A system to manage video content, comprising an index file management module comprising logic to:

generate an index file to describe content in an associated video file;

store the index file for a video file in a first memory location, separate from a second memory location in which the video file is stored;

receive, from a requesting entity, a request for access to the index file;

in response to the request, download the index file to the requesting entity; and

download the video file to the requesting entity.

14. The system of claim 13, wherein the index file management module further comprises logic to:

scan the associated video file; and

generate a video index file that indicates at least one frame boundary between frames in the index file.

15. The system of claim 13, wherein the file management module comprises logic to store the index file in a cache memory module.

16. The system of claim 13, wherein:

the request for access to the index file is received via a first communication channel;

the index file is transmitted to the requesting entity via the first communication channel; and

the video file is transmitted to the requesting entity via a second communication channel.

17. The system of claim 13, further comprising a video display system associated with the requesting entity to receive the video index file and to store the video index file in a memory module associated with the video display system.

18. The system of claim 17, wherein the video system receives at least a portion of the video file in the video display system, and stores at least a portion of the video file in a memory module associated with the video display system.

19. The system of claim 18, wherein the video system synchronizes the video index file with the at least a portion of the video file received in the video display system.

20. The method of claim 18, wherein the video system displays the at least a portion of the video file received in the video display system.
