Abstract

In one embodiment, a system comprises at least a first video source device, at least a first remote control device, a digital display device comprising logic to receive, in a digital display device, a first video signal from a first video source, extract at least a first metadata from the first video signal, use the first metadata to obtain a second video signal from a second video source, present the first video signal on the digital display device, combine at least a portion of the second video signal and at least a portion of the first video signal to generate a combined video signal, and present the combined video signal on a display.

Claims

1. A method, comprising:

receiving, in a digital display device, a first video signal from a first video source;

extracting at least a first metadata from the first video signal;

presenting the first metadata to an electronic program guide;

receiving a second video signal from the electronic programming guide;

combining at least a portion of the second video signal and at least a portion of the first video signal to generate a combined video signal;

presenting the combined video signal on a display;

receiving an input signal from a user interface associated with the display, wherein the input signal identifies an object on the display;

retrieving a second metadata associated with the object;

initiating a query to the electronic program guide;

presenting the second metadata to the electronic program guide; and

receiving a third video signal from the electronic programming guide.

2. The method of claim 1, wherein receiving, in a digital display device, a first video signal from a first video source comprises receiving a digital video stream via an input/output connector on the digital display device.

3. The method of claim 1, wherein extracting at least a first metadata from the first video signal comprises extracting metadata that uniquely identifies the video stream.

4. The method of claim 1, wherein the first metadata is presented to the electronic program guide as part of a query.

5. The method of claim 4, wherein the electronic program guide:

receives the query comprising the first metadata;

uses the first metadata as a key to retrieve a second video signal from a memory module; and

transmits the second video signal to the digital display device.

6. The method of claim 1, wherein combining at least a portion of the second video signal and at least a portion of the first video signal further comprises:

windowing the second video signal;

scaling the second video signal; and

synchronizing the second video signal with the first video signal.

7. The method of claim 1, further comprising:

combining at least a portion of the third video signal and at least a portion of the first video signal by;

windowing the third video signal;

scaling the third video signal; and

synchronizing the third video signal with the first video signal.

8. A system, comprising:

at least a first video source device;

at least a first remote control device;

a digital display device comprising logic to;

receive, in a digital display device, a first video signal from a first video source;

extract at least a first metadata from the first video signal;

present the first metadata to an electronic program guide;

receive a second video signal from the electronic programming guide;

combine at least a portion of the second video signal and at least a portion of the first video signal to generate a combined video signal;

present the combined video signal on a display;

receive an input signal from a user interface associated with the display, wherein the input signal identifies an object on the display;

retrieve a second metadata associated with the object;

initiate a query to the electronic program guide;

present the second metadata to the electronic program guide; and

receive a third video signal from the electronic programming guide.

9. The system of claim 8, wherein the digital display device further comprises logic to receive a digital video stream via an input/output connector on the digital display device.

10. The system of claim 8, wherein the digital display device further comprises logic to extract metadata that uniquely identifies a video stream.

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

initiate a query to the electronic program guide, the logic to initiate the query including the logic to present the first metadata to the electronic program guide.

12. The system of claim 8, wherein the electronic programming guide comprises logic to:

receive the query comprising the first metadata;

use the first metadata as a key to retrieve a second video signal from a memory module; and

transmit the second video signal to the digital display device.

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

window the second video signal;

scale the second video signal; and

synchronize the second video signal with the first video signal.

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

window the third video signal;

scale the third video signal; and

synchronize the third video signal with the first video signal.

15. A computer program product comprising logic instructions stored on a non-transitory computer-readable medium which, when executed by a processor, configure the processor to:

receive, in a digital display device, a first video signal from a first video source;

extract at least a first metadata from the first video signal;

present the first metadata to an electronic program guide;

receive a second video signal from the electronic programming guide;

combine at least a portion of the second video signal and at least a portion of the first video signal to generate a combined video signal;

present the combined video signal on a display;

receive an input signal from a user interface associated with the display, wherein the input signal identifies an object on the display;

retrieve a second metadata associated with the object;

initiate a query to the electronic program guide;

present the second metadata to the electronic program guide; and

receive a third video signal from the electronic programming guide.

16. The computer program product of claim 15, further comprising logic instructions stored on a non-transitory computer-readable medium which, when executed by a processor, configure the processor to:

initiate a query to the electronic program guide, wherein the logic instruction to initiate the query include the logic instructions to present the first metadata to the electronic program guide.

17. The computer program product of claim 15, further comprising logic instructions stored on a non-transitory computer-readable medium which, when executed by a processor, configure the processor to:

window the third video signal;

scale the third video signal; and

synchronize the third video signal with the first video signal.
