Brief Status Report on Scalable Video Coding Technologies

摘要

We give a ten-minute tour of scalable video coding technologies, especially those being developed under the auspices of the ISO MPEG. MPEG-4 has already accepted Fine Granularity Scalability (FGS) tools within the Streaming Video Profile. New lines of investigation are underway that include scalable coding based on the emerging Advanced Video Codec (AVC) or H.26L, called AFGS, which significantly outperforms traditional FGS based on MPEG-4, Part 2. A second new line of investigation is in developing fully embedded video coding using motion-compensated 3D wavelet coding, called Interframe Wavelet Coding. In this paper, we present a quick shapshot of these developments, highlighting new results. The encouraging new results indicate that scalable coding may be coming of age.
