Abstract
It is an object of the invention to efficiently transmit a video signal including a luminance signal and a chrominance signal. The invention includes a first processor to extract the input luminance signal every first block which is constructed by a plurality of pixels, a second processor to extract the inputted chrominance signal every second block which is constructed by a plurality of pixels, and an encoder for encoding a predetermined macro block including the first and second blocks as a unit. Another object of the invention is to provide a movement compensating method whereby a circuit scale, a calculating time, and costs, in case of executing the movement compensation, can be reduced by using the correlation between the luminance signal and the chrominance signal. To accomplish the above object, there is provided a method of performing a movement compensation between the frames or fields, whereby a movement vector of the luminance signal is detected and the movement compensation of the luminance signal and the chrominance signal is executed on the basis of the movement vector.
