摘要

In a picture coding method for generating a coded signal corresponding to each picture by coding a plurality of coded signals, a switching picture capable of switching a plurality of coded signals and following pictures of the switching picture can refer to only a group of pictures of same time in the coded signals. More specifically, the case where picture numbers of an adjacent picture of an S picture and the S picture are not continuous is not considered as an error.
