Coding method and recording and reproducing apparatus

摘要

In a coding method and a recording and reproducing apparatus, a moving image and a compressed moving image can be coded and decoded by means of the GOP sequence without using the GOP sequence information. The image frames are arranged in the same frame order in each of the plurality of GOP's. And at the same time, each of the GOP's are set so that the GOP is processed in the same GOP sequence. Then, correspondence information is set that allows the color frame sequence information to correspond to the GOP sequence on a one to one basis. The GOP sequence that corresponds to the color frame sequence information extracted from the moving image and the compressed animated image data is selected by using the set information to perform the coding process and the decoding process by means of the selected GOP sequence.
