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.

摘要： Video coding systems or apparatus utilizing context-based adaptive binary arithmetic coding (CABAC) during encoding and/or decoding, are configured according to the invention with an enhanced binarization of non-zero Delta-QP (dQP). During binarization the value of dQP and the sign are separately encoded using unary coding and then combined into a binary string which also contains the dQP non-zero flag. This invention capitalizes on the statistical symmetry of positive and negative values of dQP and results in saving bits and thus a higher coding efficiency.

摘要： A prediction error calculation part calculates a prediction error for each input data. A prediction error encoding part generates a prediction error code by encoding the value of the prediction error. A run-length counting part counts the run-length of the prediction error. When the value of the prediction error changes, a run-length encoding part generates a run-length code by encoding the run-length counted. A code connecting part generates a connected code by connecting the run-length code to the prediction error code of a corresponding prediction error. When the value of the prediction error is a particular value, a prediction error checking part selects a connected code for the prediction error, as an output code. When the value of the prediction error is a different value, the prediction error checking part selects a prediction error code for the prediction error, as an output code. A code output part outputs the output code selected.

摘要： Some disclosed embodiments are directed to methods and systems for performing pair-wise delta compression. For example, systems obtain a set of files to be compressed into a single compressed file. The system identifies different attributes related to the set of files. For each file in the set of files, the system predicts an optimized set of candidate compression files and calculates a delta between each file in the optimized set and the target file corresponding to the optimized set. After identifying the smallest delta, the system compresses the selected pair of files associated with the smallest delta in order to generate the single compressed file for the set of files.

摘要： Embodiments of this disclosure provide for a data compression method and a related data compression apparatus. In the method, to-be-compressed data and a length limit value for data compression are obtained. When the length of the data obtained by compressing the to-be-compressed data is greater than the length limit value, the to-be-compressed data is segmented based on the length limit value during compression. After the to-be-compressed data is segmented, the to-be-compressed data includes at least two compressed files after compression and a length of each compressed file is less than the length limit value.
