摘要： A decoding method according to the present invention is a method of decoding a variable length code to a Run symbol and a Level symbol. The Run symbol indicates the number of consecutive coefficients each having a value of zero. The Level symbol indicates a value of a non-zero coefficient following the Run symbol. The decoding method includes: decoding a variable length code to a code number; determining whether the code number obtained in the decoding belongs to a first range or a predetermined range; decoding the code number to a Run symbol and a Level symbol by referring to the table, when it is determined that the code number belongs to the first range; and decoding the code number to a Level symbol and then decoding a variable length code following the decoded variable length code to a Run symbol, without referring to the table, when it is determined that the code number belongs to the predetermined range.

摘要： A transmission method for transmitting coefficients representing image data is provided. The transmission method includes transmitting coded quantized coefficients obtained by coding quantized coefficients. The quantized coefficients are obtained by quantizing the coefficients using a complete quantization matrix having multiple quantization elements. The transmission method also includes transmitting a coded quantization matrix obtained by coding a truncated quantization matrix. The truncated quantization matrix is generated by truncating the complete quantization matrix. The coded quantization matrix has bits aligned in the order of bits obtained by coding the quantization elements included in the truncated quantization matrix and bits obtained by coding an end code.

摘要： A method of encoding a local time base embedded in the compressed data is disclosed. The local time base is encoded in two parts. The first part has a modulo time base that indicates the specific interval in the reference time base and the second part has a time base increment relative to the reference time. Two forms of time base increment is used to allow for the possibility of different encoding order and displaying order. A mechanism for the synchronization of multiple compressed streams with local time base is also described. A time base offset mechanism is also used to allow finer granularity synchronization of the multiple compressed streams.

摘要： A method for coding a picture segmented into a plurality of blocks. The method decodes the coded blocks to produce a reproduced image. A filter selection parameter determines a threshold value for each quantization parameter, so as to change between a mode to effect coding distortion removal by a filter and a mode not to effect the coding distortion removal. The determined filter selection parameter is coded. A difference between pixel values of pixels in the adjacent blocks on both sides of a boundary between adjacent blocks forming the reproduced image is compared with the determined threshold value determined by the filter selection parameter, and the coding distortion is removed using the filter when the difference is smaller than the threshold value, and not removed when the difference is larger than the threshold value.
