    • A method of separating data blocks with stationary informational characteristics, including the steps of sequentially collecting statistics for small data blocks in an input data set, calculating the relative change in the estimated compression efficiency for a solid block currently being formed caused by merging its statistics with the statistics of a next small block, deciding whether the small block should be added to the solid block; for any block for which the decision is no, the block is used as the starting block of the next solid block to be formed. Auxiliary block data type detection is used to improve the method.
    • 一种分离具有固定信息特征的数据块的方法,包括以下步骤:在输入数据集中顺序收集小数据块的统计数据,计算当前正在形成的实体块的估计压缩效率的相对变化, 统计下一个小块,决定是否将小块添加到实体块中; 对于决定为否的任何块,块被用作要形成的下一个实体块的起始块。 辅助块数据类型检测用于改进方法。

    • A method of compressing sorted data representation symbols sequentially. Steps include determining whether a symbol currently being encoded is identical to an immediately preceding symbol; encoding the result as a binary event; if the symbols are identical, encoding the symbol ends; if the symbols are different and there is a constant difference between several previous pairs of symbols, determining whether the difference between the current symbol a and the symbol immediately preceding it b is the same as the difference between the symbol b and the symbol immediately preceding it c, and encoding the determination result as another binary event; in the case of positive result of the latest determination, encoding the symbol ends; otherwise, encoding the symbol using a bitwise operation in which bits of the symbol's binary representation are processed sequentially from the most significant bit to the least significant bit. A corresponding decompression method is provided.
    • 一种顺序压缩分类数据表示符号的方法。 步骤包括确定当前正被编码的符号是否与紧接在前的符号相同; 将结果编码为二进制事件; 如果符号相同,则符号编码结束; 如果符号不同并且在几个先前的符号对之间存在恒定的差异,则确定当前符号a和紧接在其之前的符号b之间的差异是否与符号b和其前面的符号之间的差相同 c,并将确定结果编码为另一个二进制事件; 在最新确定的肯定结果的情况下,符号的编码结束; 否则,使用其中符号的二进制表示的比特从最高有效位顺序地处理到最低有效位的按位操作对码元进行编码。 提供相应的减压方法。

    • A video codec for real-time encoding/decoding of digitized video data with high compression efficiency, comprising a frame encoder receiving input frame pixels; a codec setting unit for setting and storing coding setting parameters; a CPU load controller for controlling desired frame encoding time and CPU loading; a rate controller for controlling frame size; a coding statistics memory for storing frequency tables for arithmetic coding of bitstream parameters and a reference frame buffer for storing reference frames. The frame encoder comprises a motion estimation unit, a frame head coding unit, a coded frame reconstruction and storage unit and a macroblock encoding unit. The macroblock encoding unit provides calculation of texture prediction and prediction error, transforming texture prediction error and quantization of transform coefficient, calculation of motion vector prediction and prediction error and arithmetic context modeling for motion vectors, header parameters and transform coefficients. The codec also includes a deblocking unit for processing video data to eliminate blocking effect from restored data encoded at high distortion level, which may be a part of encoder or decoder, an internal resize unit, providing matching downscaling of a frame before encoding and upscaling of decoded frame according to the coding setting parameters, and a noise suppression unit.
