摘要： Systems and methods for controlling the flow of information content in a network are described. The system includes a tracking module that remembers a sensitivity level of the information content and a location of that information content with respect to the system. A marking module is included that receives the sensitivity level from the tracking module upon a call for the information content. The marking module marks a sensitivity tag in a packet header associated with the information content according to the sensitivity level. Flow of the information content in the network is controlled according to the sensitivity tag.

摘要： In a packet based multicast video streaming network, a method for minimizing delay in displaying video on a TV set in response to a viewer changing the channel is disclosed. For each live multicast video stream, one or more reference frames and corresponding compressed frames are temporarily stored in a memory in anticipation of the viewer switching to that particular program. When the viewer changes channels, the previously stored reference and compressed frames are immediately read from the memory and rendered for display on the TV. This eliminates the need to wait for the next available reference frame. In other words, this eliminates a temporary blank TV screen each time the channel is changed. Certain compressed frames are dropped and blank frames can be inserted in order to catch up to and synchronize with the live video broadcast. The particular frames to be dropped and the number of blank frames to be inserted is a function of the bandwidth limitation imposed by the last mile of the network.
摘要翻译：在基于分组的多播视频流网络中，公开了一种用于响应于观看者改变频道而在电视机上显示视频的延迟最小化的方法。对于每个实时多播视频流，预期观众切换到该特定节目，一个或多个参考帧和对应的压缩帧被临时存储在存储器中。当观众改变频道时，先前存储的参考和压缩帧立即从存储器中读出并呈现在TV上显示。这消除了等待下一个可用参考帧的需要。换句话说，这消除了每次通道改变时的临时空白电视屏幕。某些压缩帧被丢弃，并且可以插入空白帧以便赶上并与实时视频广播同步。要删除的特定帧和要插入的空白帧的数量是由网络的最后一英里施加的带宽限制的函数。

摘要： A method and apparatus for determining information associated with a particular multicast channel in a multicast network are disclosed. In accordance with the method, a request message requesting information associated with the particular multicast channel is generated and sent to the multicast network. Further, the request message is propagated downstream in a recursive manner via a multicast topology of the multicast network. A response to the request message is propagated upstream via the multicast topology to generate a response message including requested information associated with the particular multicast channel. The information may comprise number of users receiving the particular multicast channel.

摘要： A power sourcing equipment-powered device (PSE-PD) combination unit requests inline power from a connected PSE or other PSE-PD combination unit by having the PD portion of the PD-PSE combination unit adapt its electrical characteristics, if necessary, to obtain the maximum power available. The PD-PSE combination device keeps track of available power less power consumed locally with a summation unit. A PSE manager unit grants PD power requests from downstream devices based upon the available power left (e.g., original PSE power less losses less local consumption).
摘要翻译：电源设备供电设备（PSE-PD）组合单元通过使PD-PSE组合单元的PD部分适应其电气特性（如果需要）来请求来自连接的PSE或其他PSE-PD组合单元的内联电力以获得最大功率可用。 PD-PSE组合设备通过求和单元跟踪可用功率消耗在本地消耗的功率。 PSE管理器单元基于剩余的可用功率（例如，原始PSE功率损耗减少本地消耗）向下游设备授予PD功率请求。
