PURPOSE:To change a quantizing bit number and a forecast formula or the like corresponding to kinds of picture signals RGB by transmitting information such as line number and dot number of a picture to be coded as a frame header. CONSTITUTION:Forecast coding is attained by adding a frame header and a line header in addition to coded data as a code series coding still picture information. Each frame is constituted by RGB chrominance component in case of the still picture information. The frame identification information represents the frame identification and the frame kinds such as RGB. The line information represents the information such as line number or the like constituting a frame and the dot information represents the information of a dot number constituting a line. The coded information represents information such as quantized bit number (n) or the like of the forecast coding system. The transmission efficiency is improved by changing the quantized bit number (n) as to each RGB component depending on the information amount of the RGB component. |
