摘要： A circular buffer in a video delivery server tracks a second copy of a live video stream to provide instant replay capability. When an end-user initiates the instant replay function, the circular buffer is copied to an instant-replay buffer, from which a replay of the video is sent to the end-user. During replay the end-user can use playback functions such as pause, slow-play, freeze frame, etc. Upon leaving the replay function the end user rejoins the live stream. The circular buffer also enables transmission of delayed copies of the live stream, time-shifted by predetermined intervals, which copies are multicasted to end-users. Upon request, an end-user may join a delayed version of interest. This allows the user to replay interesting content by jumping to a time-delayed version without missing the show and to catch up with real-time during e.g. commercial breaks.
摘要翻译：视频传送服务器中的循环缓冲器跟踪实时视频流的第二副本以提供即时重放功能。当最终用户启动即时重放功能时，循环缓冲区被复制到即时重放缓冲器，从该重放缓冲区将视频的重放发送给最终用户。在重播期间，终端用户可以使用诸如暂停，慢播，冻结帧等的播放功能。在离开重放功能时，终端用户重新加入直播流。循环缓冲器还能够传输实时流的延迟副本，以预定间隔进行时移，哪些副本被多播给最终用户。根据要求，最终用户可以加入感兴趣的延迟版本。这允许用户通过跳转到时间延迟版本而重播播放有趣的内容，而不丢失节目并且在例如播放期间赶上实时。商业休息。

摘要： A computer-implemented method comprises a plurality of operations. An operation is performed for creating an IP packet containing MPEG (Moving Picture Experts Group) packets therein and having a header including a value computed using a respective bit value of each one of the MPEG packets. Thereafter, an operation is performed for analyzing the computed value to determine an importance of the MPED packets relative to decoded video quality of a video stream including the MPEG packets.

摘要： A bridge/router and method are described herein that are capable of avoiding packet replication at layer 2 where there is a failure in a network. In one embodiment, the bridge/router is informed about a fault which occurred within the network. Then, the bridge/router makes a determination about whether or not multiple LSPs would be used to flood/carry the same IP traffic out off a single port. If yes, the first bridge/router chooses one of the LSPs to carry the IP traffic out the single port and then prevents the IP traffic from being carried on the remaining LSP(s) out the single port which avoids the packet replication on a link which is associated with the single port. If no, then the first bridge/router allows the IP traffic to be carried on the LSPs out off more than one port.

摘要： The PIP system enables display of a mosaic of favorite channels in a Picture-in-Picture (PIP) format to a subscriber terminal. Picture-in-Picture support is efficiently provided by sending only I-Frames of the secondary video channel to the end-user. That is, any unnecessary packets (null, B-P frames, audio, etc.) in the secondary video channel are stripped away. This method uses very little bandwidth and is STB agnostic.

摘要： A server at the edge of a broadband network distributes multimedia content streams to clients, while ensuring that the first data delivered to each client is key data (milestones) needed for correctly decoding the stream content. This is obtained by buffering the packets in the incoming stream and transmitting the packets from the buffer in an outgoing stream, starting with the most recent milestone placed in the buffer before a request to join the respective incoming stream is received. As the writing to and reading from the buffer are performed at different rates, the incoming and outgoing streams are eventually synchronized, at which point the client may be switched to receive the incoming stream directly.
摘要翻译：宽带网络边缘的服务器将多媒体内容流分发到客户端，同时确保传送给每个客户端的第一个数据是正确解码流内容所需的关键数据（里程碑）。这是通过缓冲输入流中的数据包，并从输出流中的缓冲区中传送数据包，从接收到相应输入流的请求之前的缓冲区中最新的里程碑开始。当以不同的速率执行对缓冲器的写入和读取时，输入和输出流最终被同步，在这一点上，客户端可以被直接切换以接收输入流。

摘要： In a system that provides decoding of A/V streams, this invention reduces switching delays between different streams by modifying the Program Identification (PID) values of the Audio and Video data to common PID values that are already known by the decoder. This technique allows the decoder to stay in a run state when switching between A/V streams, thereby reducing channel change times.
