摘要： Disclosed is a system and method of managing video content quality. The method includes receiving performance data at a video quality prediction system where the performance data is related to a plurality of network elements of a network path linking a video-head end with a set-top box device. The method also includes predicting, based at least partially on the performance data, a quality of video content received at the set-top box device and determining whether the predicted quality of video content is greater than or equal to a video quality threshold. In addition, the method includes identifying at least one of the plurality of network elements not satisfying a performance requirement, based on the performance data, when the predicted quality of video content is less than the video quality threshold. Further, the method includes outputting data indicating the at least one network element not satisfying the performance requirement.

摘要： A system and method is disclosed for detecting distribution of multimedia content. The volume level of data traffic is monitored for a plurality of users to select any users with high-bandwidth usage. The time of day and the day of the week may be considered when determining whether a user is a high-bandwidth user. Upon selecting a user as one with high-bandwidth usage, such user may be subject to packet inspections of data traffic streams. In some embodiments, content identification parameters or watermarks are added to one or more packets in a data traffic stream carrying multimedia content.

摘要： According to one example embodiment the placement of video distribution servers and acquisition servers in a live television IPTV network is considered to be a separate process. This process may be based, for example, on historical data, number of subscribers, subscribers' service quality, some video distribution servers may be selectively placed closer to the subscribers, i.e., at some central offices or intermediate offices, instead of at the video hub office. These local video distribution servers (those video distribution servers not located at video hub office) may selectively receive popular TV channel streams just like regular video subscribers based on the multicasting protocol from the acquisition server. Whenever a subscriber wants to switch to a channel (or recover packet loss for an on-going channel), if the channel is on the popular channel list, the service may be accomplished by the local video distribution servers. Otherwise, the service will be provided by the remote video distribution servers (those placed together with acquisition servers). This approach may facilitate faster channel change and quick packet loss recovery, decreased traffic load on the service networks, and improvement in the subscribers video packets delivery performance.

摘要翻译： 根据一个示例性实施例，视频分配服务器和采集服务器在实况电视IPTV网络中的放置被认为是单独的过程。 该过程可以基于例如历史数据，订户数量，订户的服务质量，一些视频分发服务器可以被选择性地放置在更靠近用户的位置，即在一些中心局或中间局，而不是在视频 枢纽办公室。 这些本地视频分发服务器（那些不在视频中心局的视频分发服务器）可以根据来自采集服务器的多播协议选择性地接收流行的TV频道流，就像常规视频订阅者一样。 每当用户想要切换到频道（或恢复正在进行的频道的分组丢失）时，如果频道在流行频道列表上，则该服务可以由本地视频分配服务器完成。 否则，该服务将由远程视频分发服务器（与采集服务器放在一起的服务器）提供。 这种方法可以促进更快的信道改变和快速的分组丢失恢复，降低业务网络上的业务负载，以及改善用户视频分组传送性能。
