摘要： 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.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.
摘要翻译：即使通过IP线路（高达24 Mbits / sec），路由器和多媒体单元之间的高速可用，这仍然是数据传输方面的瓶颈。实际上实际上，绝大多数IP用户的访问速度在2到5Mbits / sec之间，并且开发其他服务（电话，视频会议，推送VOD，游戏）是带宽消耗的。现在本发明的目的是提出一种通过IP线路减少路由器和多媒体单元之间的数据流的解决方案。这通过一种优化路由器和多媒体单元之间的数据流的方法来实现，路由器接收形成服务的至少一个数据流，并且包括几个子流，其中一部分由多媒体单元替代地使用，方法包括以下步骤：定义表示多媒体单元简档的一组数据，将该组数据发送到路由器，由路由器根据给定的简档过滤不必要的子流，将剩余的子流发送到多媒体单元。

摘要： The present invention aims at solving the financial revenue loss due to the presence of digital video recorders that allow skipping the commercial breaks.The solution is based on a method to control the access to conditional access audio/video content comprising at least one advertisement section, said content being played on a digital video recorder associated with a security module (SM) and being formed by at least an advertisement section and a main content section, this method comprising the steps of: defining a control information associated with the audio/video content, said control information being stored in the security module, updating the control information in the security module with condition information included in an Control Message relating to the advertisement section of the audio/video content, receiving by the security module of an Control Message relating to the main content section of said audio/video content and containing a condition information in relation with the stored control information, verifying that the condition information contained in the Control Message relating to the main content section match with the stored control information, and in the positive event, returning to the digital video recorder an authorization signal allowing the access the main content section of the audio/video content.
摘要翻译：本发明旨在解决由于存在允许跳过商业休息的数字录像机的财务收入损失。该解决方案基于一种控制对包括至少一个广告部分的条件访问音频/视频内容的访问的方法，所述内容在与安全模块（SM）相关联的数字视频记录器上播放，并且由至少一个广告该方法包括以下步骤：定义与音频/视频内容相关联的控制信息，所述控制信息存储在安全模块中，使用包括在安全模块中的条件信息来更新安全模块中的控制信息与音频/视频内容的广告部分相关的控制消息，由安全模块接收与所述音频/视频内容的主要内容部分相关的控制消息，并且包含与所存储的控制信息相关的条件信息，验证包含在与主内容部分相关的控制消息中的条件信息匹配存储的控制信息，并且在正面事件中，返回到数字视频记录器，允许访问音频/视频内容的主内容部分的授权信号。
