Coding method and recording and reproducing apparatus

摘要

A method for coding a video signal made up of a plurality of sequential video frames. First, correspondence information relating color frame information values to types of video coding is provided, the color frame information values and types of coding being related on a one to one basis such that for each value of color frame information there is only one corresponding type of coding. Next, a value of color frame information is determined for each video frame and the type of coding to be used on the frame is selected by associating the frame's color frame information with a coding type via the correspondence information. Finally, the image frames are coded according to the coding types selected by referencing the correspondence information.
