Problems solved by technology

This is where the problem arises: the synchronization of the coordinated reproduction of these different contents on the user interface
However, this scheme only defines the starting point of all media, and does not verify that the media content data chunks are all available on the terminal when they should be executed synchronously
As a result, if a packet is lost in transit over the network, or its arrival diverges from other packets that should be synchronized with it, different packets corresponding to different media are no longer in sync

Embodiment Construction

[0030] figure 1 A system for transmitting multimedia data to a client terminal 2 is shown. At one end of the link of this system 1, a data server 3 of various contents is shown, called a media server. These content servers can contain any type of content. For example, the server 30 may be a text data server, the server 31 may be an image server, and the server 32 may be an animation server. In response to the loading request of the server 4, the three servers send their specific data to the MMS relay server 4. Then, various data are converted according to a predetermined format. For example, the conversion means 41 at the input of the server 4 are means of the SMIL standard, which was described in detail at the beginning of this application. The SMIL standard is a text format supported by a certain number of Internet industrial applications (Internet browsers, content readers, etc.). After said device 41 completes the transformation of the media data, said data is reorgan...

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.

Description

technical field [0001] The present invention relates to the communication field, and in particular to a device for generating multimedia files sent to a communication terminal from multiple sets of data, the multiple sets of data corresponding to one type of multimedia file content respectively. [0002] The invention also relates to a multimedia file for sending to a communication terminal, the file includes a plurality of data packets. [0003] In particular, the network commonly referred to as "Internet mobile" offers good prospects for application of the method and apparatus of the present invention. [0004] The invention more particularly belongs to the field of multimedia data communication services. The multimedia data is, for example, video, audio, picture, text, hypertext data and other data. Background technique [0005] To date, the distribution of information over communication networks has used some rather unique techniques. In particular the "Pull" techniqu...
