Abstract

Method and software product for transferring data, plus equipment for controlling data transfer in a multimedia system that includes a group of participants' terminals, with which multimedia data generated by participants' terminals contained in the group are sent to one or more participants' terminals contained in the group and played back there. A central synchronization unit generates synchronization labels containing time information and sends them to the participants' terminals contained in the group, and the synchronization labels are used to play back information in modified time.

First claim

The invention claimed is:

1. A computer-implemented method for modifying multimedia data, the method comprising:
generating a synchronization label comprising time information;
attaching the synchronization label to the multimedia data;
modifying the time information according to a time context for the multimedia data to generate modified multimedia data; and
causing the modified multimedia data to be played.

2. The computer-implemented method of claim 1 , wherein causing the modified multimedia data to be played comprises causing the modified multimedia data to be played in accordance with the time context.

3. The computer-implemented method of claim 1 , wherein attaching the synchronization label to the multimedia data comprises attaching the synchronization label to a data packet.

4. The computer-implemented method of claim 1 , wherein generating the synchronization label comprises generating the synchronization label to correspond to a periodic time sequence.

5. The computer-implemented method of claim 4 , wherein the period time sequence comprises a period length equal to or shorter than a data packet with a shortest period length.

6. The computer-implemented method of claim 1 , wherein the synchronization label further comprises a context tag, a conversation tag, or a media tag.

7. The computer-implemented method of claim 1 , wherein the time information is based on a preset starting time.

8. A non-transitory, computer-readable medium, storing instructions that, when executed by a processor, causes:
generating a synchronization label comprising time information;
attaching the synchronization label to multimedia data;
modifying the time information according to a time context for the multimedia data to generate modified multimedia data; and
causing the modified multimedia data to be played.

9. The non-transitory, computer-readable medium of claim 8 , wherein causing the modified multimedia data to be played comprises causing the modified multimedia data to be played in accordance with the time context.

10. The non-transitory, computer-readable medium of claim 8 , wherein attaching the synchronization label to the multimedia data comprises attaching the synchronization label to a data packet.

11. The non-transitory, computer-readable medium of claim 8 , wherein generating the synchronization label comprises generating the synchronization label to correspond to a periodic time sequence.

12. The non-transitory, computer-readable medium of claim 11 , wherein the period time sequence comprises a period length equal to or shorter than a data packet with a shortest period length.

13. The non-transitory, computer-readable medium of claim 8 , wherein the synchronization label further comprises a context tag, a conversation tag, or a media tag.

14. The non-transitory, computer-readable medium of claim 8 , wherein the time information is based on a preset starting time.

15. A multimedia system, comprising:
a processor;
a memory operatively connected to the processor and storing instructions that, when executed by the processor, causes:
generating a synchronization label comprising time information;
attaching the synchronization label to multimedia data;
modifying the time information according to a time context for the multimedia data to generate modified multimedia data; and
causing the modified multimedia data to be played.

16. The multimedia system of claim 15 , wherein causing the modified multimedia data to be played comprises causing the modified multimedia data to be played in accordance with the time context.

17. The multimedia system of claim 15 , wherein attaching the synchronization label to the multimedia data comprises attaching the synchronization label to a data packet.

18. The multimedia system of claim 15 , wherein generating the synchronization label comprises generating the synchronization label to correspond to a periodic time sequence.

19. The multimedia system of claim 18 , wherein the period time sequence comprises a period length equal to or shorter than a data packet with a shortest period length.

20. The multimedia system of claim 15 , wherein the time information is based on a preset starting time.
