摘要： The invention utilizes low complexity estimates of complex functions to perform combinatorial coding of signal vectors. The invention disregards the accuracy of such functions as long as certain sufficient properties are maintained. The invention in turn may reduce computational complexity of certain coding and decoding operations by two orders of magnitude or more for a given signal vector input.

摘要： Improved methods for coding an ensemble of pulse vectors utilize statistical models (i.e., probability models) for the ensemble of pulse vectors, to more efficiently code each pulse vector of the ensemble. At least one pulse parameter describing the non-zero pulses of a given pulse vector is coded using the statistical models and the number of non-zero pulse positions for the given pulse vector. In some embodiments, the number of non-zero pulse positions are coded using range coding. The total number of unit magnitude pulses may be coded using conditional (state driven) bitwise arithmetic coding. The non-zero pulse position locations may be coded using adaptive arithmetic coding. The non-zero pulse position magnitudes may be coded using probability-based combinatorial coding, and the corresponding sign information may be coded using bitwise arithmetic coding. Such methods are well suited to coding non-independent-identically-distributed signals, such as coding video information.
摘要翻译： 用于对脉冲向量的集合进行编码的改进方法利用脉冲向量的集合的统计模型（即，概率模型）来更有效地对集合的每个脉冲向量进行编码。 使用统计模型和给定脉冲向量的非零脉冲位置的数量来编码至少一个描述给定脉冲向量的非零脉冲的脉冲参数。 在一些实施例中，使用范围编码来编码非零脉冲位置的数量。 可以使用条件（状态驱动）逐位算术编码来编码单位幅度脉冲的总数。 可以使用自适应算术编码对非零脉冲位置位置进行编码。 可以使用基于概率的组合编码对非零脉冲位置幅度进行编码，并且可以使用按位算术编码对相应的符号信息进行编码。 这种方法非常适合编码非独立同分布的信号，例如编码视频信息。

摘要： A encoder/decoder architecture that uses an arithmetic encoder to encode the MSB portions of the output of a Factorial Pulse Coder, that encodes the output of a first-level source encoder, e.g., MDCT. Sub-parts (e.g., frequency bands) of portions (e.g., frames) of the signal are suitably sorted in increasing order based on a measure related to signal energy (e.g., signal energy itself). In a system that overlays Arithmetic Encoding on Factorial Pulse coding results in bits re-allocated to bands with higher signal energy content yielding higher signal quality and higher bit utilization efficiency.
