    • A method of restricting access to content delivered via a video distribution network is disclosed and includes receiving a control stream at a service delivery platform. The control stream is related to media content delivered via a video distribution network. The method also includes parsing the control stream and determining, from the parsed control stream, at least one geographical area in which access to programming associated with the video content channel is to be restricted. The method also includes automatically scheduling a conditional access event associated with the media content at least one video head-end of the video distribution network, the at least one video head-end serving the at least one geographical area. In a particular embodiment, the video distribution network can be an Internet Protocol Television (IPTV) network.
    • 公开了一种限制对通过视频分发网络传送的内容的访问的方法,并且包括在服务递送平台处接收控制流。 控制流与通过视频分发网络传送的媒体内容有关。 该方法还包括解析控制流并从解析的控制流确定至少一个地理区域,在该地理区域中对与视频内容信道相关联的编程的访问将被限制。 该方法还包括自动地调度与媒体内容相关联的条件访问事件,视频分发网络的至少一个视频前端,服务于至少一个地理区域的至少一个视频头端。 在特定实施例中,视频分配网络可以是因特网协议电视(IPTV)网络。

    • A method includes receiving, at a component of a multimedia content distribution system, a command including blackout information related to a first version of content. The blackout information includes scheduling information. The method includes updating a first entry within a control matrix based on the blackout information in response to the command. The first entry includes information related to when the first version of the content in a first stream is to be blacked out based on the scheduling information. The method also includes updating a second entry within the control matrix based on the blackout information in response to the command. The second entry includes information related to when the second version of the content in a second stream is to be blacked out based on the scheduling information. The method also includes sending a control stream based on the control matrix to one or more set top boxes.
    • 一种方法包括在多媒体内容分发系统的组件处接收包括与第一内容版本有关的中断信息的命令。 停电信息包括调度信息。 该方法包括响应于该命令,基于中断信息来更新控制矩阵内的第一条目。 第一条目包括与第一流中的内容的第一版本基于调度信息被中断时相关的信息。 该方法还包括基于响应于该命令的中断信息来更新控制矩阵内的第二条目。 第二条目包括与第二流中的内容的第二版本根据调度信息被中断时相关的信息。 该方法还包括基于控制矩阵向一个或多个机顶盒发送控制流。
