Abstract

Disclosed are techniques for a system and protocol that provides for composition of a video scene that embeds one or more video sequences into a background image. The protocol enables a video stream presentation system (e.g., IPTV) to automate the embedding by one or more decoders of video sequence content and non-background information, for example, stock tickers, close caption, or date/time information, into a background.

Claims

1. A method of video presentation at a decoder, comprising:

receiving a layout including at least one marked area;

receiving and decoding at least one picture of at least one video sequence or crawler; and

rendering at the decoder the at least one received and decoded picture by replacing the pixels of the marked area with the received and decoded picture.

2. The method of claim 1, wherein the marked area is marked by at least one of an alpha channel, a color, and a texture.

3. The method of claim 1, wherein the marked area contains information related to a video sequence.

4. The method of claim 3, wherein the information related to a video sequence comprises a bar code.

5. The method of claim 1, wherein the layout is received from an application server.

6. The method of claim 5, wherein the layout is received from the application server using an SVCS.

7. The method of claim 1, wherein the at least one video sequence or crawler is received using an SVCS.

8. The method of claim 1, wherein the receiving and decoding comprises receiving and decoding at least one picture of the crawler, the crawler including at least one of:

a stock ticker, sport results, close caption information, progress bars, day of the week, calendar date, and time of day.

9. A non-transitory computer-readable medium having a set of instructions programmed to perform the methods of one of claims 1-8.

10. A system for presenting video at a decoder, the system including:

a decoder configured to;

receive a layout, wherein the layout includes at least one marked area;

receive and decode at least one picture of at least one video sequence or crawler; and

render the at least one received and decoded picture by replacing the pixels of the marked area with the decoded picture.

11. The system of claim 10, wherein the marked area is marked by at least one of an alpha channel, a color, and a texture.

12. The system of claim 10, wherein the marked area contains information related to a video sequence.

13. The system of claim 12, wherein the information related to a video sequence is in the form of a bar code.

14. The system of claim 10, further comprising:

an application server, in communication with the decoder, wherein the layout is obtained from the application server.

15. The system of claim 10, further comprising an SVCS, in communication with the decoder, wherein the decoder is further configured to receive the layout from the application server using the SVCS.

16. The system of claim 10, further comprising an SVCS, in communication with the decoder, wherein the at least one picture of at least one video sequence or crawler is received by the decoder using an SVCS.

17. The system of claim 10, wherein at least one video sequence or crawler comprises at least one crawler, wherein the crawler includes at least one of:

a stock ticker, sport results, close caption information, progress bars, day of the week, calendar date, and time of day.
