Method of encoding image signal, apparatus for encoding image signal, method of decoding image signal, apparatus for decoding image signal, and image signal recording medium

摘要

An image signal encoding method and apparatus is provided. An input image signal is coded to produce coded picture signals. Specifically, the coded picture signals include a group-of-pictures consisting of predictive coded pictures and bi-directionally predictive coded pictures. For at least some of the predictive coded pictures of the group-of-pictures, slices are designated which consist entirely of intra-coded macroblocks. An indication of the slices designated is provided in the coded picture signals.
