摘要： A hardware data compressor for compressing a block of characters. A first hardware engine finds a match of a string of characters at a current location in the block with an earlier occurrence in the block of the string of characters, determines a first size that is a total number of bits into which the matched string would be Huffman encoded as literals using a Huffman code table, calculates a back pointer from the current location to the earlier occurrence of the string, and determines a second size that is a number of bits into which the back pointer would be Huffman encoded using the Huffman code table. A second hardware engine Huffman encodes the matched string if the first size is less than the second size and otherwise Huffman encodes the back pointer.

The method includes determining a characteristic of the audio content, the characteristic of the audio content including at least one of a type or a property of the audio content. Also the method includes classifying the audio content based on the characteristic of the audio content and determining probabilities for multiple predefined audio coding symbols associated with the audio content by calculating a probability for each of the audio coding symbols based on the result of the classification, the probability for an audio coding symbol indicating a frequency at which the audio coding symbol occurs in the audio content. Further, the method encoded the audio content based on the audio coding symbols and the corresponding probabilities to obtain a code value, the code value representing a compression coding format of the audio content.

摘要： The entropy coding of a current part of a predetermined entropy slice is based on, not only, the respective probability estimations of the predetermined entropy slice as adapted using the previously coded part of the predetermined entropy slice, but also probability estimations as used in the entropy coding of a spatially neighboring, in entropy slice order preceding entropy slice at a neighboring part thereof. Thereby, the probability estimations used in entropy coding are adapted to the actual symbol statistics more closely, thereby lowering the coding efficiency decrease normally caused by lower-delay concepts. Temporal interrelationships are exploited additionally or alternatively.
