ABSTRACT:
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.
