Abstract

A method of synchronizing first and second streams of a multimedia content program is operable for determining a temporal difference indicative of a relative timing between first and second streams of the program, the first stream being provided to a first multimedia processing resource (MPR) and the second stream being provided to a second MPR. The method includes manipulating at least one of the streams to reduce the temporal difference until the temporal difference is less than a predetermined threshold and enabling a viewer of the first stream to interact with a viewer of the second stream regarding the program. Interactions are visually detectable on a first display screen corresponding to the first MPR.

First claim

What is claimed is:

1. A multimedia content delivery method, comprising:
accessing information indicative of a temporal difference between a first stream of particular content and a second stream of the particular content;
modifying the first stream to reduce the temporal difference; and
in accordance with detecting a value of the temporal difference less than a particular threshold:
detecting an interaction between a first viewer of the first stream and a second viewer of the second stream; and
including a visually detectable indication of the interaction in a display of the particular content to the first viewer.

2. The method of claim 1 , further comprising:
identifying the second stream from a plurality of streams as a stream with which to synchronize the first stream.

3. The method of claim 2 , wherein identifying the second stream includes identifying the second stream in accordance with buddy list information associated with the first stream.

4. The method of claim 3 , wherein identifying the second stream includes identifying the second stream in accordance with affinity information included in the buddy list information.

5. The method of claim 4 , wherein the affinity information influences an aggressiveness of the modifying of the first stream.

6. The method of claim 3 , further comprising:
selectively displaying visually detectable indications of particular viewers of the particular content, where the particular viewers comprise viewers identified in the buddy list information.

7. The method of claim 1 , wherein the information indicative of the temporal difference comprises information indicative of a difference between a first timestamp associated with the first stream and a second timestamp associated with the second stream.

8. The method of claim 7 , wherein the first timestamp and the second timestamp indicate respective start times of the first stream and the second stream.

9. The method of claim 8 , wherein the first timestamp and the second timestamp indicate respective times for processing a particular frame within the respective streams.

10. The method of claim 1 , wherein modifying the first stream includes inserting first added content into the first stream and second added content into the second stream wherein a difference in duration of the first added content and the second added content is approximately equal to the temporal difference.

11. The method of claim 10 , wherein modifying the first stream includes inserting the first added content at a point of the particular content selected in accordance with reducing perceptible flicker.

12. The method of claim 1 , further comprising:
displaying a visually detectable representation of a second viewer.

13. The method of claim 12 , wherein the visually detectable representation of the second viewer overlays a display of the particular content.

14. A computer readable medium, including processor executable program instructions, that, when executed by a processor, cause the processor to perform operations comprising:
accessing information indicative of a temporal difference between a first stream of a multimedia program and a second stream of the multimedia program;
modifying the first stream to reduce the temporal difference; and
in accordance with detecting a value of the temporal difference less than a particular threshold:
detecting an interaction between a first viewer of the first stream and a second viewer of the second stream; and
including a visually detectable indication of the interaction in a display of the multimedia program to the first viewer.

15. The computer readable medium of claim 14 , wherein modifying the first stream includes inserting a first added content sequence into the first stream and a second added content sequence into the second stream wherein a difference in duration of the first added content sequence and the second added content sequence is approximately equal to the temporal difference.

16. The computer readable medium of claim 15 , wherein the first added content sequence comprises a first advertising sequence and the second added content sequence comprises a second advertising sequence and wherein modifying the first stream includes inserting the first added content sequence at point of the particular content selected in accordance with reducing perceptible flicker.

17. The computer readable medium of claim 14 , wherein the operations include:
identifying the second stream from a plurality of streams as a stream with which to synchronize the first stream, wherein identifying the second stream includes identifying the second stream in accordance with buddy list information associated with the first stream.

18. The computer readable medium of claim 17 , wherein affinity information included with the buddy list information influences an aggressiveness of the modifying of the first stream.

19. An application server, comprising:
a network interface adapter for coupling to a network;
a processor; and
a computer readable storage device including processor executable program instructions that, when executed by the processor, cause the processor to perform operations comprising:
accessing information indicative of a temporal difference between a first stream of a multimedia program and a second stream of the multimedia program;
modifying the first stream to reduce the temporal difference; and
in accordance with detecting a value of the temporal difference less than a particular threshold:
detecting an interaction between a first viewer of the first stream and a second viewer of the second stream; and
including a visually detectable indication of the interaction in a display of the multimedia program to the first viewer.

20. The server of claim 19 , wherein modifying the first stream includes inserting first added content into the first stream and second added content into the second stream wherein a difference in duration of the first added content and the second added content is approximately equal to the temporal difference.
