摘要： A scalable layered video coding scheme that encodes video data frames into multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video, adds error resilience to the enhancement layer. Unique resynchronization marks are inserted into the enhancement layer bitstream in headers associated with each video packet, headers associated with each bit plane, and headers associated with each video-of-plane (VOP) segment. Following transmission of the enhancement layer bitstream, the decoder tries to detect errors in the packets. Upon detection, the decoder seeks forward in the bitstream for the next known resynchronization mark. Once this mark is found, the decoder is able to begin decoding the next video packet. With the addition of many resynchronization marks within each frame, the decoder can recover very quickly and with minimal data loss in the event of a packet loss or channel error in the received enhancement layer bitstream. The video coding scheme also facilitates redundant encoding of header information from the higher-level VOP header down into lower level bit plane headers and video packet headers. Header extension codes are added to the bit plane and video packet headers to identify whether the redundant data is included.

摘要： An information handling system includes a multi-core processor that processes variable-length code (VLC) bitstream data. The bitstream data includes multiple codewords that the processor organizes into functionally common subsets. The processor includes a general purpose processor (GPU) and one or more special purpose processor (SPUs). An SPU of the processor may includes two SPU buffers. The processor first transfers bitstream data into GPU buffer memory and then populates the SPU buffers one after another with bitstream data. The SPU buffers may each include an overlap region that the SPU populates with the same bitstream data. The SPU parses the bitstream data in the SPU buffers in alternating fashion. The SPU may shift parsing from the one SPU buffer to the other SPU buffer when parsing reaches a subset boundary within an overlap region.

摘要： A cross descriptor learning system, method and program product therefor. The system extracts descriptors from unlabeled exemplars. For each unlabeled exemplar, a cross predictor uses each descriptor to generate labels for other descriptor. An automatic label generator also generates labels for the same unlabeled exemplars or, optionally, for labeled exemplars. A label predictor results for each descriptor by combining labels from the cross predictor with labels from the automatic label generator.

摘要翻译： 将视频数据帧编码成多层的可分级的分层视频编码方案，包括具有越来越高质量视频的较低质量视频和多个增强层的基本层，向增强层增加了错误恢复能力。 将独特的再同步标记插入到与每个视频分组相关联的报头中的增强层比特流中，与每个位平面相关联的报头以及与每个视频平面（VOP）段相关联的报头。 在传输增强层比特流之后，解码器尝试检测分组中的错误。 在检测到时，解码器在比特流中向前寻找下一个已知的再同步标记。 一旦找到该标记，解码器就可以开始对下一个视频数据包进行解码。 通过在每个帧内添加许多重新同步标记，解码器可以在接收到的增强层比特流中的分组丢失或信道错误的情况下非常快速地恢复并且具有最小的数据丢失。 视频编码方案还有助于将标题信息从较高级别的VOP头部冗余编码到较低级位平面头部和视频分组头部。 标题扩展码被添加到位平面和视频分组报头，以标识是否包括冗余数据。
