摘要

In a moving picture data structure having a structure comprising I pictures (intraframe coded image) and P pictures (interframe forward predictive coded image), a P' picture of a forward predictive coded image of a picture immediately preceding an I picture and the I picture is placed following the I picture. If an error occurs during the I picture transmission, the P' picture can be used to recover from the error.
