摘要： A method and apparatus to improve error resiliency in processing a multimedia bitstream is described. A directory of header information is generated for a multimedia bitstream. The directory information comprises packet header information associated with the multimedia bitstream. The directory information may be transmitted to a receiver along with the multimedia bitstream. A receiver of the multimedia bitstream and the directory can utilize the header information to identify and locate packets within and subsequent to erroneous data in the received bitstream. By identifying and locating packets that may otherwise be discarded, the receiver may be able to improve error recovery and decoding of the multimedia data.

摘要： In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

摘要翻译： 通常，本公开描述了用于在多个编码器模块和多路复用模块之间交换信息的技术，以组合来自编码器模块的数据段与改进的总体质量。 特别地，编码器模块将它们各自的数据段与质量和速率信息相关联，并将至少与数据段相关联的质量和速率信息发送到多路复用模块。 多路复用模块分析质量和速率信息，以确定编码器模块希望在当前超帧中包括的数据段是否适合传输信道的可用带宽内。 如果复用模块确定多个数据段不适合可用带宽，则多路复用模块基于从编码器模块接收的质量和速率信息来选择要调整大小的一个或多个段。
