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 a user interface in a digital display device, comprising:

establishing a communication connection between the digital display device and at least one video source device;

initiating a handshake process between the digital display device and the video source device;

selecting one of the digital display device or the video source device as the primary interface device manager and one of the digital display device or the video source device as the secondary interface device manager;

initiating, from the primary interface device manager, a request for a user interface database from the secondary interface device manager; and

receiving in the primary interface device manager, a user interface database from the secondary interface device manager;

merging the user interface database from the secondary interface device manager with a user interface database from the primary interface device manager to form a merged user interface database; and

storing the merged user interface database in a memory module coupled to the primary interface device manager.

2. The method of claim 1, wherein selecting one of the digital display device or the video source device as the primary interface device manager and one of the digital display device or the video source device as the secondary interface device manager comprises:

transmitting at least one graphics processing capability parameter associated with the video source device to the digital display device;

comparing the graphics processing at least one graphics processing capability parameter associated with the video source device with a corresponding graphics processing capability parameter associated with the digital display device; and

assigning the primary interface device manager to a device associated with the higher graphics processing capability.

3. The method of claim 1, further comprising:

transmitting a user interface suppression mode signal from the primary interface device manager to the secondary interface device manager;

receiving, at the secondary interface device manager, the user interface suppression mode signal; and

in response to the user interface suppression mode signal, disabling the user interface controller in the secondary interface device manager.

4. The method of claim 3, further comprising:

in response to the user interface suppression mode signal, activating a user interface relay service in the secondary interface device manager.

5. The method of claim 4, further comprising:

receiving, in the secondary interface device manager, a control signal requesting access to a user interface; and

passing the control signal via the user interface relay service to the primary user interface device.

6. The method of claim 1, further comprising:

transmitting the merged user interface database from the primary interface device manager to the secondary interface device manager; and

storing the merged user interface database in a memory module coupled to the secondary interface device manager.

7. The method of claim 6, further comprising:

receiving, in the primary interface device manager, a power off signal; and

reassigning the secondary interface device manager as the primary interface device manager.

8. A system, comprising:

at least one video source device;

a digital display device comprising logic to;

establish a communication connection between the digital display device and at least one video source device;

initiate a handshake process between the digital display device and the video source device;

receive, a user interface database from the video source device;

merge the user interface database from the video source device with a user interface database from the digital display device to form a merged user interface database; and

store the merged user interface database in a memory module coupled to the digital display device.

9. The system of claim 8, wherein the digital display device further comprises logic to transmit a user interface suppression mode signal from the digital display device to the video source device;

and

wherein the video source device comprises logic to;

receive the user interface suppression mode signal; and

in response to the user interface suppression mode signal, disable the user interface controller in the video source device.

10. The system of claim 8, wherein the video source device further comprises logic to activate a user interface relay module in the video source device in response to the user interface suppression mode signal.

11. The system of claim 10, wherein the video source device further comprises logic to:

receive a control signal requesting access to a user interface; and

pass the control signal via the user interface relay module to the video display device.

12. The system of claim 8, wherein the digital display device further comprises logic to:

transmit the merged user interface database from the digital display device to the video source device; and

store the merged user interface database in a memory module coupled to the video source device.

13. The system of claim 12, wherein the digital display device further comprises logic to:

receive a power off signal; and

reassign the secondary interface device manager as the primary interface device manager.

14. A system, comprising:

a digital display device; and

at least one video source device comprising logic to;

establish a communication connection between the digital display device and at least one video source device;

initiate a handshake process between the digital display device and the video source device;

receive, a user interface database from the digital display device;

merge the user interface database from the digital display device with a user interface database from the video source device to form a merged user interface database; and

store the merged user interface database in a memory module coupled to the video source device.

15. The system of claim 14, wherein the video source device further comprises logic to transmit a user interface suppression mode signal from the video source device to the digital display device;

and

wherein the digital display device comprises logic to;

receive the user interface suppression mode signal; and

in response to the user interface suppression mode signal, disable the user interface controller in the digital display device.

16. The system of claim 15, wherein the digital display device further comprises logic to activate a user interface relay module in the video source device in response to the user interface suppression mode signal.

17. The system of claim 16, wherein the digital display device further comprises logic to:

receive a control signal requesting access to a user interface; and

pass the control signal via the user interface relay module to the video display device.

18. The system of claim 14, wherein the video source device further comprises logic to:

transmit the merged user interface database from the video source device to the digital display device; and

store the merged user interface database in a memory module coupled to the secondary interface device manager.

19. The system of claim 18, wherein the video source device further comprises logic to:

receive a power off signal; and

reassign the digital display device as the primary interface device manager.
