摘要： A method is provided for processing multilayer bit streams that includes receiving the multilayer bit streams of Scalable Video Code (SVC) each having a base layer and at least one enhancement layer. One or more of the enhancement layers are extracted in whole or in part from at least one of the multilayer bit streams so that the multilayer bit streams are collectively reduced in their total bandwidth. Each of the extracted bit streams are rewritten to a single layer bit stream. The single layer bit streams are then multiplexed to form a multiplexed single layer bit stream that is non-SVC.
摘要翻译：提供了一种用于处理多层比特流的方法，其包括接收每个具有基本层和至少一个增强层的可伸缩视频码（SVC）的多层比特流。一个或多个增强层从多层比特流中的至少一个全部或部分提取，使得多层比特流在它们的总带宽中被共同减少。每个提取的比特流被重写为单层比特流。然后单层比特流被多路复用以形成非SVC的复用单层比特流。

摘要： A method for processing a plurality of multilayer bit streams includes receiving a plurality of multilayer bit streams each having a base layer and at least one enhancement layer. One or more of the enhancement layers are extracted in whole or in part from at least one of the multilayer bit streams so that the plurality of multilayer bit streams are collectively reduced in their total bandwidth. Each of the multilayer bit streams are rewritten to a single layer bit stream. The single layer bit streams are multiplexed to form a multiplexed single layer bit stream.

摘要： Progressive scan encoded JPEGS are decoded sequentially on a Minimum Coded Unit (MCU) basis and then the JPEG image is output one row at a time to a frame buffer. Since the entire image does not need to be decoded at once, a huge JPEG buffer is generally not required. The present invention reconstructs each MCU one scan at a time to produce complete lines of image data and thus provides an output using the image data on a line-by-line basis. This technique may require that each MCU be reconstructed scan-by-scan. This technique provides a modified entropy (Huffman) decoder in which data for different scans of an MCU of the progressively scanned JPEG image may be stored in a buffer, and a parsing and scan table element creates pointers to the memory buffer corresponding to the start of each scan level. Scan tables are also extracted for each level of scan or points to the same tables if some scan levels use the same table.
摘要翻译：逐行扫描编码的JPEGS以最小编码单元（MCU）为依次解码，然后将JPEG图像一行一行地输出到帧缓冲器。由于整个图像不需要一次解码，因此通常不需要巨大的JPEG缓冲区。本发明一次重构每个MCU一次扫描以产生完整的图像数据行，并且因此在逐行的基础上提供使用图像数据的输出。这种技术可能需要逐个扫描重建每个MCU。该技术提供了一种修改的熵（Huffman）解码器，其中逐渐扫描的JPEG图像的MCU的不同扫描数据可以存储在缓冲器中，并且解析和扫描表元素产生指向与存储缓冲器每个扫描级别。如果某些扫描级别使用相同的表格，扫描表也会为每个扫描级别提取，或指向相同的表。
