摘要： Motion graphics keying in the compressed domain may be accomplished by receiving a compressed video stream comprising one or more source macroblocks, receiving a keyed graphics stream, determining which of the one or more source macroblocks overlaps with the keyed graphics stream, decoding only the one or more overlapping macroblocks to create one or more decoded macroblocks, combining the keyed graphics stream with the one or more decoded macroblocks to create a composited video stream, encoding the composited video stream to create an encoded composited video stream, and restoring the encoded composited video stream in the compressed video stream in place of the one or more overlapping macroblocks.

摘要： Multiple-frame format data streams are selectively encrypted at a master head-end prior to distribution. Selective encryption includes monitoring packet for frame header information. Only packets that do not contain frame header information are encrypted, while those that contain frame header information are left unencrypted. Splicers at distribution hubs can then interject local content into the data streams and forward these to individual subscribers at the local node groups.
摘要翻译：多帧格式数据流在分发之前在主头端被选择性地加密。选择性加密包括监视帧头信息的数据包。只有不包含帧头信息的数据包被加密，而包含帧头信息的数据包不被加密。分销中心的接头可以将本地内容插入到数据流中，并将其转发到本地节点组的单个用户。

摘要： An auto-adaptive program distribution system in which content is transmitted from one or more content providers to one or more subscribers each associated with a service group includes an auto-adaptive switch whose inputs is a set of programs from the content providers and whose outputs are grouped into at least two groups, the first of which is dedicated to broadcast programming directed to multiple service groups, and the second of which is dedicated to switched programming sent to one or more of the service groups. The switched programming group includes at least one program selected on an on-demand basis. The auto-adaptive switch is provided with an analysis module which handles the group allocation, and makes its assignments based on statistical analyses performed in accordance with prescribed algorithms which take factors such as seasonal television viewership, seasonal and aberrational events and programming, time of day, week, year, and so forth.

摘要： A method and apparatus for optimizing the data transfer rate over a transport layer (i.e., communication link) such as the Internet is provided. Initially the data is prepared for transmission by a transfer rate controller, then the data is encoded by a Forward Error Correction (FEC) encoder. After the data has been transferred over the transport layer, the quality of the data transfer link is assessed by an FEC decoder that determines if any errors occurred during data transfer and if errors are detected, the magnitude of the errors (i.e., FEC-correctable packets, FEC-uncorrectable packets). This information is used to generate a feedback message which is used by the transfer rate controller to adjust and optimize the data transfer rate for the link quality as determined at that point in time. By continually monitoring and assessing link quality and providing feedback to the transfer rate controller, the transfer rate can be continually adapted to the varying link quality. In addition to generating feedback used by the transfer rate controller to optimize data transfer rate, the FEC decoder can generate feedback that is used by the FEC encoder to optimize the FEC algorithm. If desired, feedback from the FEC decoders within the link layer demodulator and/or feedback from the receiver can be used to augment the feedback generated by the FEC decoder.
摘要翻译：提供了一种用于优化诸如因特网之类的传输层（即，通信链路）上的数据传输速率的方法和装置。最初，数据准备好由传输速率控制器传输，然后数据由前向纠错（FEC）编码器编码。在通过传输层传输数据之后，数据传输链路的质量由FEC解码器来评估，FEC解码器确定在数据传输期间是否发生任何错误，并且如果检测到错误，则错误的大小（即，可纠错的分组，FEC不可校正分组）。该信息用于生成由传送速率控制器用于调整和优化在该时间点确定的链路质量的数据传输速率的反馈消息。通过持续监控和评估链路质量并向传输速率控制器提供反馈，传输速率可以不断适应不同的链路质量。除了产生由传输速率控制器使用的优化数据传输速率的反馈之外，FEC解码器可以产生由FEC编码器用于优化FEC算法的反馈。如果需要，来自链路层解调器中的FEC解码器和/或来自接收机的反馈的反馈可以用于增加由FEC解码器产生的反馈。

摘要： A system for conducting fast-channel switching of programming delivered as compressed data streams over a unicast channel includes a switch for receiving both fully-compressed and a partially-compressed versions of the data streams corresponding to available programming. Upon receiving a channel change request from a user, the switch switches to a partially compressed data stream of the requested program and delivers this data stream over the unicast channel. The switch then monitors a fully-compressed data stream of the requested program, and upon encountering an anchor frame therein, switches to delivery of the fully-compressed version of the requested program over the unicast channel.

摘要： In a video system having an encoder and multiple decoders, a snooping circuit in each decoder compares an address on a common data bus to determine whether encoded video data is read or written by a host computer. When the address on the common data bus is detected to be an address within a predetermined range, the read or write data on the common data bus is latched into a first-in-first-out (FIFO) memory. A decoding circuit in each decoder decodes from the FIFO memory to provide a decoded video data output stream. In this manner, multiple decoders can be supported by the video system without additional bandwidth demand on the host computer.
