    • A method is intended for disseminating content data in a peer-to-peer mode between peers connected to at least one communication network. This method comprises the steps of: i) making peers exchange neighboring information between them to build a bipartite peer overlay comprising a first group, comprising peers having a complete content to be disseminated, and a second group, comprising peers having not this content or only a part of it and having links therebetween, ii) disseminating the data defining the content (and preferably encoded with erasure correcting codes) from peers of the first group to first peers of the second group according to the bipartite peer overlay, iii) disseminating the data received by the first peers to other peers of the second group according to the bipartite peer overlay, and iv) updating the bipartite peer overlay when a peer of the second group has fully completed the content.
    • 一种方法旨在在连接到至少一个通信网络的对等体之间以对等模式传播内容数据。 该方法包括以下步骤:i)使对等体在它们之间交换相邻信息,以构建包括第一组的双重对等层覆盖,包括具有要传播的完整内容的对等体,以及第二组,包括不具有该内容的对等体 其一部分并且在它们之间具有链接,ii)根据第二组的第二组的第一对等体,将定义内容(并且优选地由擦除校正码编码)的数据传播到第二组的第一对等体,iii)传播 所述第一对等体根据所述第二组对等体重叠向所述第二组的其他对等体接收的数据,以及iv)当所述第二组的对等方已经完全完成所述内容时,更新所述二分对等体覆盖。

    • A method and apparatus are described for protecting real time media including receiving media packets, generating media bit strings from the media packets, applying a forward error correcting code across the generated media bit strings to generate at least one forward error correcting bit string and generating at least one forward error correcting packet from the at least one forward error correcting bit string. Also described are a method and apparatus for recovering from losses of real time media packets including forming media bit strings from received media packets, forming forward error correcting bit strings from received forward error correcting packets, decoding the formed media bit strings and forward error correcting bit strings to obtain recovered media bit strings and recover lost media packets from the recovered media bit strings. Further described is a data structure for a forward error correcting header on computer readable media.

    • The invention concerns a method for assigning parts of multimedia files to distributed storage devices, the number of said devices being an integer n, characterized in that it comprises the following steps: a step consisting in dividing each multimedia file in windows, which represent data for contiguous playback of a given duration; a step consisting, for each multimedia file, in determining a number k so that any original window of file can be recovered from any k distinct symbols; a step consisting, for each window of each said multimedia files, in assigning n corresponding symbols to said devices, one to each device, the n distinct symbols being created using erasure coding; and a step consisting in partially or totally filling the storage memory left on each device after said first steps with prefix windows of said multimedia files.
    • 本发明涉及一种用于将多媒体文件的部分分配给分布式存储设备的方法,所述设备的数量为整数n,其特征在于包括以下步骤:步骤包括:将窗口中的每个多媒体文件划分为 给定持续时间的连续播放; 对于每个多媒体文件,包括确定数字k的步骤,使得可以从任何k个不同符号恢复任何原始文件窗口; 对于每个所述多媒体文件的每个窗口,包括向所述设备分配n个相应符号,每个设备一个,使用擦除编码创建的n个不同符号; 以及在所述第一步骤之后部分或完全填充每个设备上剩余的存储存储器的步骤,其中包含所述多媒体文件的前缀窗口。

    • The present invention relates to a module and a process for inter-user communication across a bidirectional network. The module comprises a unit for triggering recording, in a storage space of a server, of information received by the server from users via the bidirectional network, and a unit for controlling a broadcasting of data stored in the storage space to the users, via a broadcasting network. It also comprises a unit for monitoring connection of the users to the server via the bidirectional network. Moreover, the unit for triggering recording and/or the unit for controlling broadcasting is designed to operate as a function of the users connected to the server which are identified by the monitoring unit. Advantageously, the bidirectional network is temporary and the broadcasting network is a permanent unidirectional network. Applications to P2P technology, in particular for television.
