ABSTRACT:
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.
