摘要

The lossless coding method includes determining a lossless coding mode of a quantization coefficient as one of an infinite range lossless coding mode and a finite range lossless coding mode; Encoding the quantization coefficients in an infinite range lossless coding mode in response to a result of determining the lossless coding mode; And encoding the quantization coefficient in a finite range lossless coding mode in response to a result of determining the lossless coding mode.
