摘要：
An advanced video multiplexer system designed and optimized for next generation on-demand video distribution is described. The system optimizes identifies a multi-program transport stream best able to accommodate new seesions based upon Quality of Service (QoS) and QAM utilization ratios. MPTS channels are rebalanced via re-grouping and transrating as necessary to optimize bandwidth utilization. Multiple video formats are supported via built-in transcoding. The multiplexer manages encryption resources and supports new sessions using previously allocated encryption resources where possible. Sessions can be grouped into encryption channels either by using a single authorization tier per channel policy, or by requiring all clients of the group to be in physically separated service groups. Encryption channels can be released when a channel no longer serves any clients or when one or more other channels that have been assigned the same entitlement can accommodate any remaining clients.

描述了针对下一代按需视频分发设计和优化的高级视频多路复用器系统。 该系统优化识别出最佳能够根据服务质量（QoS）和QAM利用率来适应新视角的多节目传输流。 MPTS通道可以根据需要通过重新分组和转换进行重新平衡，以优化带宽利用率。 通过内置转码支持多种视频格式。 多路复用器管理加密资源，并在可能的情况下使用先前分配的加密资源支持新会话。 会话可以通过使用每个渠道策略的单个授权层，或者要求组中的所有客户端在物理上分离的服务组中，将其分组到加密通道中。 当通道不再为任何客户端服务时，或者一个或多个其他被分配了相同授权的渠道可以容纳任何剩余的客户端时，可以释放加密通道。
