A SCALABLE CODING FRAMEWORK FOR EFFICIENT VIDEO ADAPTATION

Current digital video applications require video coding techniques that cater a wide range of quality levels, spatial resolutions and frame rates supporting different user preferences, varying transmission bandwidths and terminal capabilities. Efficient adaptation of video content is vital in such application environments. Encoding video in scalable formats support fast and efficient adaptation. This paper presents a flexible scalable video coding framework that supports mandatory scalability functionalities required for video adaptation. The encoder, decoder and extractor modules of the framework, the scalable bits stream descriptions and video adaptation are presented.
