    • An audio/video content receiver being configured to receive media content from a content source by a broadcast data path, the media content being arranged as a plurality of media channels comprises a host module having a tuner configured to assign logical channel indices to the media channels to allow selection, at the host module, of one or more of the media channels for reproduction by selecting the corresponding logical channel index, the host module storing channel association data associating the logical channel indices with the received media channels; and a removable conditional access module (CAM), the CAM having an access control unit for decoding access-controlled encoded broadcast content, the host module and the removable CAM being arranged to provide an encrypted communication link for decoded access-controlled encoded broadcast content between the CAM and the host module; in which: the host module is configured to acquire channel association data via the broadcast data path; the CAM is configured to provide further channel association data to the host module; the host module comprises a detector configured to detect a conflict of logical channel index between the channel association data acquired by the host from the broadcast data path and the channel association data provided by the CAM and, in the case of a conflict, to detect one or more unused logical channel indices; and the CAM is configured to select one of the unused logical channel indices for use by a media channel for which the logical channel index defined in the CAM's channel association data conflicts with a logical channel index defined in the host's channel association data.
    • 音频/视频内容接收器被配置为通过广播数据路径从内容源接收媒体内容,媒体内容被布置为多个媒体信道包括主机模块,该主机模块具有被配置为向媒体信道分配逻辑信道索引的调谐器 允许通过选择对应的逻辑信道索引在主机模块处选择一个或多个媒体信道进行再现,所述主机模块存储将逻辑信道索引与所接收的媒体信道相关联的信道关联数据; 以及可移动条件访问模块(CAM),所述CAM具有用于解码访问控制的编码广播内容的访问控制单元,所述主机模块和所述可移动CAM被布置为提供用于经解码的访问控制的编码广播内容的加密通信链路 CAM和主机模块; 其中:所述主机模块被配置为经由所述广播数据路径获取频道关联数据; CAM被配置为向主机模块提供另外的信道关联数据; 主机模块包括检测器,其被配置为检测由主机从广播数据路径获取的信道关联数据与由CAM提供的信道关联数据之间的逻辑信道索引的冲突,并且在冲突的情况下检测一个 或更多未使用的逻辑信道索引; 并且所述CAM被配置为选择所述未使用的逻辑信道索引之一,以供由所述CAM信道关联数据中定义的所述逻辑信道索引与在所述主机的信道关联数据中定义的逻辑信道索引冲突的媒体信道使用。

    • A method of reducing interference to reception of streams of television content received at a television receiver in which each of the streams of television content are transmitted on one of a plurality of frequency channels in accordance with a channel map which defines on which of the plurality of frequency channels each stream of television content is transmitted and the interference being caused by a base station transmitting data to or receiving data from one or more mobile devices via radio communication signals in a vicinity of the television receiver. The method includes identifying the channel map and adapting a transmission of the radio communication signals between the base station and the one or more of mobile devices in accordance with the identified channel map to reduce interference at the television receiver.
    • 一种降低对在电视接收机接收的电视接收流的接收干扰的方法,其中电视内容的每一个在多个频道中的一个频道上被发送,该频道图根据定义了多个 频率信道传输电视内容的每个流,并且干扰是由基站通过电视接收机附近的无线电通信信号向一个或多个移动设备发送数据或从其接收数据引起的。 所述方法包括:根据所识别的频道映射,识别频道映射并适应基站与一个或多个移动设备之间的无线电通信信号的传输,以减少电视接收机的干扰。
