Abstract
Different types of media (text, sound, animated images, . . . ) are transmitted to a relay center. According to the invention, this data is split up in terms of common synchronization points (PS0, . . . , PS4), and packets are assembled together combing all of the data of each media type that is defined between identical synchronization points. As a result, each packet contains data that is to be executed simultaneously on the telecommunications terminal. A particular application lies with mobile terminals.
Claims7
1/ A device for generating a multimedia file (5) for sending to a telecommunications terminal (2), the file being made up of data groups (track #1, track #2) corresponding to respective types of content in the multimedia file, the device being characterized in that it comprises:
- means for splitting up each of said data groups into respective pluralities of data subgroups as a function of synchronization points (PS0, . . . , PS4) associated respectively with the beginning and the end of execution on man-machine interface means of the terminal, the subgroups associated with identical respective beginning and end synchronization points being for simultaneous execution on the man-machine interface means;
- and
- assembly means (11) for assembling the multimedia file in the form of a plurality of packets (8, 9, . . . ) each comprising a plurality of data subgroups (83, 84, . . . , 93, 94, . . . ) associated with respective identical beginning and end synchronization points.
2/ A device according to claim 1, characterized in that it has description means (12) for describing the synchronization points in the multimedia file.
3/ A device according to claim 1 or claim 2, characterized in that said data groups comprise text data, optionally animated image data, optionally compressed sound.
4/ A relay server suitable for receiving data groups (track #1, track #2, . . . ) corresponding to respective types of multimedia content, for delivering a multimedia file grouping together said data groups, the server being characterized in that it includes a multimedia file generator device according to any one of claims 1 to 3.
5/ A multimedia file for sending to a telecommunications terminal (2), said file comprising a plurality of data packets (8, 9, . . . ) and being characterized in that:
- each of said data packets corresponds to a concatenation of data subgroups (83, 84, . . . , 93, 94, . . . ) relating to respective types of multimedia file content and associated with respective identical synchronization points (PS0, . . . , PS4) for the beginning and the end of execution on man-machine interface means.
6/ A multimedia file according to claim 5, characterized in that it comprises description means (12) for describing the synchronization points associated with the multimedia file.
7/ A multimedia file according to claim 5 or claim 6, characterized in that the telecommunications terminal to which said file is to be sent is a mobile terminal of the type comprising a radiotelephone and/or a personal digital assistant provided with wireless telecommunications means, or a fixed terminal of the personal computer type connected to the Internet.
