Technology - Audio-Visual Coding 3 - MPEG 4 Video and VRML

Synopsis

We explain how Advanced Video Coding (AVC/H.264) improves on MPEG-2 video compression. The MPEG-4 standards are of unprecedented scope, including animation, synthetic sound and video, VRML interactivity and Java. We introduce these technologies and discuss how they can be used together to provide services and communication systems far beyond the modes we are familiar with today. We also discuss the MPEG-7 metadata and MPEG-21 digital rights management standards.
