摘要： Even if high speed are available between the router and the multimedia unit through the IP line (up to 24Mbits/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 5Mbits/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. This is achieved by a method to optimize the data stream between a router and a multimedia unit, the router receiving at least one data stream forming a service and comprising several sub-streams from which part of them are alternatively used by the multimedia unit, the method comprising the steps of : - defining a set of data representing the multimedia unit's profile, - transmitting this set of data to the router, - filtering by the router the unnecessary sub-stream according the given profile, - sending the remaining sub-streams to the multimedia unit.

摘要： Method and cryptographic system for descrambling content packets (15) included within a digital transport stream (10) together with conditional access messages (12) and header data (15') of these content packets (15). This method requires a deciphering algorithm (35), processed by a descrambler (36) of a multimedia unit (30), using an initialization vector (33) as first input and a control word (13) as second input. This unit is connected with a security module (40) for processing the conditional access messages (12) and extracting thereof said control words (13). This initialization vector (33), or intermediate data (33') to determine the initialization vector (33), is the result of cryptographic function (44) based on at least input data (43) extracted from the digital transport stream (10) and processed into the security module (40).
