摘要： A system, method and computer program product provide finer rate control in data compression by processing a data stream through a plurality of parallel subbands, wherein a first subband processes the data differently than a second subband. Separate shift quantization parameters for each separate run-of-zeros compressed storage area or pile can be provided, instead of a single common shift parameter for every coefficient as in the prior art. The parameter value for each such area or pile can be recorded in the compressed output file. The separate shift quantization parameters can also be adjusted dynamically as data is being compressed.
摘要翻译： 系统，方法和计算机程序产品通过处理通过多个并行子带的数据流来提供数据压缩中的更精细的速率控制，其中第一子带处理不同于第二子带的数据。 可以提供针对每个单独的零级压缩存储区域或堆的单独的移位量化参数，而不是如现有技术中的每个系数的单个公共移位参数。 每个这样的区域或桩的参数值可以记录在压缩的输出文件中。 单独的移位量化参数也可以随着数据被压缩而动态地调整。

摘要： A system, method and computer program product having optimal matching to a known or measured probability distribution encodes data without the use of an excessively large lookup table. An encoder constructed according to the present invention uses two or more different encoding methods in combination. In one embodiment, Huffman coding by table lookup is combined with computational generation, such as by using an exponential Golomb equation. The most commonly occurring elements are looked up in a small Huffman table, while the remaining elements are coded with the equation. In another embodiment, data is encoded using two or more equations. In yet another embodiment, data is encoded using multiple tables in conjunction with one or more equations.

摘要： A coder and/or decoder system and method are provided including a variable modulus. As an option, the modulus may reflect a steepness of a probability distribution curve associated with a compression algorithm (i.e. a negative exponential of the probability distribution). Moreover, the modulus may depend on a context of a previous set of data, while avoiding increasing as a function of a run length (i.e. a plurality of identical bits in a sequence).
