摘要：We often use simulcast video data to provide multi-quality video over broadband networks. However, this is not superior from the viewpoint of efficient transmission and data storage. Moreover, scalable coding was selected as an MPEG standard, but the fact that the scaled bitstream cannot be reconstructed by a generic decoder is a problem. Previously, proposed updatable scalability adapted generic decoders in simulcast. Therefore, in this paper, we propose a video cache and delivery method with scalable architecture. Through simulation experiments, we found that scalable architecture is better in user access models than simulcast, which is explained in this paper.
