发明名称 System and method for enhancing data compression using dynamic learning and control
摘要 A data compression system and method for achieving enhanced compression performance in a plurality of encoder-decoder pairs communicatively coupled in a concatenated chain is disclosed. The plurality of encoder-decoder pairs receive input data and transform the input data into compressed output data. The data compression system includes at least one quality estimator communicatively coupled to the concatenated chain to determine a plurality of quality metrics corresponding to an output from each of the plurality of encoder-decoder pairs. Further, the data compression system also includes a processing subsystem configured to optimize the operation of each of the plurality of encoder-decoder pairs based upon the plurality of quality metrics to achieve a desired level of optimization for the concatenated chain.

主权项 1. A data compression system, comprising: a plurality of encoder-decoder pairs communicatively coupled in a concatenated chain and configured to receive input data and transform the input data into compressed output data, wherein the plurality of encoder-decoder pairs each comprise: a first encoder-decoder pair comprising: a first encoder configured to compress and to encode the input data; and a first decoder configured to decode the data encoded and compressed by the first encoder and to provide decoded data to a subsequent encoder-decoder pair; and at least one additional encoder-decoder pair comprising: an additional encoder configured to receive decoded data from a prior encoder-decoder pair and to compress and encode the decoded data; andan additional decoder configured to decode the data encoded by the additional encoder and to provide the data decoded by the additional decoder to a subsequent encoder-decoder pair or provide the data decoded by the additional decoder as output data of the concatenated chain when there are no subsequent encoder-decoder pairs in the concatenated chain; at least one quality estimator communicatively coupled to the concatenated chain to determine one or more quality metrics corresponding to the decoded data provided by the first decoder, the decoded data provided by the additional decoder of the at least one addition encoder-decoder pairs, or a combination thereof; and a processing subsystem configured to optimize operation of each of the plurality of encoder-decoder pairs based upon the plurality of quality metrics, to achieve a desired level of optimization for the concatenated chain.
