Abstract

a data formatting part for converting the ratio of luminance signal and a chromatic signal of a image signal into a ratio 4:2:0 in a line; a scrambling part for rearranging an image data into a predetermined block in order to scramble a plane pat where information is scarcely changed from a changing part where the information is changed a lot; a DCT part for converting an output of the scrambling part into a binary data; an activity producing part for determining the size between an encoding area and a quantization; a quantization part for performing the quantization of a constant of the DCT; an adaptive scanning part for adaptively scanning the data quantified according to the encoding area; a variable encoding part for counting the amount of the information for an output of the adaptive scanning part; and a serial transmitting part for transmitting the amount of information to coincide with the transmission speed by adding "0" to a block where underflow is generated.
