摘要： Various disclosed implementations allow a flexible amount of redundancy to be used in coding. In one general implementation, information is accessed for determining which of multiple encodings of at least a portion of a data object to send over a channel (310). A set of the multiple encodings is determined for sending over the channel, with the set including at least one and possibly more of the multiple encodings, and the number of encodings in the set being based on the accessed information (320). In a more particular implementation, the redundant slice feature of the H.264/AVC coding standard is used, and a variable number of redundant slices is transmitted for any given picture based on current channel conditions.
摘要翻译：各种公开的实现允许在编码中使用灵活的冗余量。在一般的实现中，访问信息以确定通过信道（310）发送的数据对象的至少一部分的多个编码中的哪一个。确定多个编码的集合用于通过信道发送，其中该集合包括多个编码中的至少一个可能的多个编码，并且该集合中的编码的数量是基于所访问的信息（320）。在更具体的实现中，使用H.264 / AVC编码标准的冗余片段特征，并且基于当前信道条件为任何给定图像发送可变数量的冗余片段。

摘要： There are provided method and apparatus for detecting and concealing reference and non-reference video frames. A video decoder includes an entropy decoder (110), an error detector (176), and an error concealer (178). The entropy decoder (110) is for decompressing a video bitstream intended to have a fixed frame rate and parsing the decompressed video bitstream to find picture order counts for frames of the decompressed video bitstream. The error detector (176) is for determining that a particular frame of the decompressed video bitstream is missing based upon the picture order counts. The error concealer (178) is for concealing the particular frame. The method is accomplished by decompressing and parsing the video bitstream to find picture order counts for frames of the decompressed video bitstream and then determining (224, 228) that a particular frame of the decompressed video bitstream is missing based upon comparison of their associated picture order counts, and then concealing (244) that particular frame.

摘要： A traffic optimizer facilitates communication of data packets using a unicast protocol between a server and at least one of a plurality of clients through a multicast network. The traffic optimizer includes a communication processor and a packet processor. The communication processor receives both data including association data and the data packets using the unicast protocol from the server. The association data includes IP addresses of the server and IP addresses of at least one of a plurality of clients available for communication. The packet processor processes the data packets to optimize data transfer in response to an analysis of the data packets, and forwards the processed data packets to at least one of the plurality of clients at respective ones of the received IP addresses through a multicast network using the unicast protocol.
