摘要： Provided are a method, system, and program for decoding compressed data. Compressed data is received and decoded. An error is detected while decoding a first location in the compressed data. A reentry data set is accessed having a pointer to a second location in the compressed data following the first location and decoding information that enables decoding to start from the second location. The second location in the compressed data is accessed and the decoding information in the accessed reentry data set is used to continue decoding the compressed data from the second location.

摘要： Apparatus and methods are provided for encoding independently decodable pieces of compressed data to accommodate reordering of the pieces of compressed data before or after manipulation. Encoding can occur before or after manipulation of the source information. For example, in the context of a JPEG image, MCUs can be rotated and promptly compressed with restart markers without extra buffering to put the MCUs in the correct rotated order. Later, the order of the independently decodable pieces can be changed to accommodate proper output. Alternatively, pointers to the independently decodable pieces can be used to present the data to the decoder in the proper order. Additional reentry information within the independently decodable pieces of compressed data can allow initiation of decoding at other than the independently decodable points. Such reentry information preferably would include bit-level pointers and sufficient state information to initialize the decoder properly. For example, in the context of a JPEG image, in addition to the typical information available to the decoder that has been passed in earlier markers, the reentry information for a given MCU boundary may include: a bit-level pointer to the first block's DC Huffman code, the position of the output, and a DC predictor for each component of the MCU.
摘要翻译：提供装置和方法用于编码独立可解码的压缩数据片段以适应在操纵之前或之后对压缩数据的重新排序。编码可以在操作源信息之前或之后发生。例如，在JPEG图像的上下文中，可以使用重新启动标记旋转并及时压缩MCU，而无需额外的缓冲，以使MCU以正确的旋转顺序。之后，可以改变独立可解码片段的顺序以适应正确的输出。或者，可以使用指向独立可解码片的指针以正确的顺序将数据呈现给解码器。可独立解码的压缩数据段内的附加折返信息可以允许在独立解码点之外的其它解码开始。这种重入信息最好包括位级指针和足够的状态信息，以正确地初始化解码器。例如，在JPEG图像的上下文中，除了已经在早期标记中传递的解码器可用的典型信息之外，给定MCU边界的重入信息可以包括：指向第一块的DC的位级指针霍夫曼代码，输出位置以及MCU的每个组件的直流预测器。

摘要： Provided is a method, system, program, and data structure for decompressing a compressed data stream whose decoded output comprises lines of two-dimensional data or other data whose decoding depends upon previously decoded data and where the desired output is only part of sequentially decoded output. Received are a compressed data set, at least one pointer to a location in the compressed data stream whose decoded output comprises a location on a line of data, and decoding information for each received pointer that enables decoding from a point within the compressed data stream addressed by the pointer. For each received pointer, the following steps are performed: (i) accessing the location in the compressed data stream addressed by the pointer in the reentry data set; and (ii) using the decoding information in the reentry data set to decode compressed data from the accessed location.

摘要： The scaling down of data is provided. At least two blocks of transformed data samples representing at least two blocks of original data samples are received. One of at least two tables of constants is selected wherein each table of constants is capable of reducing the number of transformed data samples by a different factor. The constants taken from the selected table are applied to the at least two blocks of transformed data samples to produce one block of transformed data samples representing one block of final data samples. The data is processed one dimension at a time by multiplying the data in one dimension with selected constants taken from previously developed tables corresponding to the desired scale down factor. Scaling down by different factors in each dimension as well as scaling down in one dimension and scaling up in the other dimension may be achieved. In addition, the de-quantization of the quantized transform coefficients may be accomplished by pre-multiplication of the selected constants when the quantization values are known. In a similar way the re-quantization may be accomplished by a pre-division of the selected constants. Both de-quantization and re-quantization may be combined when the input quantized transform coefficients and output quantized transform coefficients are desired.

摘要： Provided is a method, system, program, and data structures for decompressing a compressed data stream. The compressed data stream is decoded a first time to generate multiple reentry data sets. Each reentry data set includes a pointer to a location in the data stream and decoding information that enables decoding to start from the location addressed by the pointer. The compressed data stream is then decoded from the beginning to a point preceding a location addressed by a first reentry data set. For each generated reentry data set, the location in the compressed data stream addressed by the pointer in the reentry data set is accessed. The decoding information in the reentry data set is then used to decode compressed data from the accessed location to a point preceding the location addressed by the pointer in the next reentry data set. For concatenated bit planes, the original multi-bit pixel values are reassembled in buffers and then outputted.

摘要： The invention provides a method, data compression system, apparatus, and article of manufacture which reduce the error in transform equations in which constants are replaced by approximations. According to the invention transform constants are replaced with approximations which are a function of an integer and a floating point value. The transform equation is then performed with the integers in place of the constants. The floating point value may be applied either to the result of the equation or to the data to be processed by the transform equation before the equation is performed. Further the floating point value may be applied using a fixed precision version of the value or a fixed precision value into which the floating point value has been factored.
