Abstract: Even if high speed are available between the router and the multimedia unit through the IP line (up to 24 Mbits/sec), this is still the bottleneck in term of data transfer. Indeed in practice the vast majority of IP users have access speed between 2 to 5 Mbits/sec and the development of other services (telephony, videoconference, push VOD, game) are bandwidth consuming. It is now an object of the invention to propose a solution to reduce the data flow between the router and the multimedia unit over IP line.

Abstract: This invention concerns a decoder for processing Pay-TV data. This decoder is associated to a security module by means of identification data and includes means for deactivating the processing of the Pay-TV data. Furthermore, it includes a counter that acts on the deactivation means according to the content of this counter. The invention also concerns a Pay-TV data management system including at least two decoders like those defined above, this system being characterized in that at least one of the security modules is declared master and includes means for reinitializing said decoder counters. The invention furthermore concerns a management process for at least two decoders for processing Pay-TV data, said decoders being associated to a subscriber and including means for deactivating the processing of Pay-TV data and a counter that acts on said deactivation means. Each subscriber also disposes of at least two security modules that can be locally connected to a decoder.
