摘要：<P>PROBLEM TO BE SOLVED: To provide video coding techniques that support spatial scalability using a generalized fine granularity scalability (FGS) approach. <P>SOLUTION: Spatially scalable enhancement bitstreams can be arbitrarily truncated to conform to network conditions, channel conditions and/or decoder capabilities. Coding coefficients and syntax elements for spatial scalability can be embedded in a generalized FGS format. For good network or channel conditions, and/or enhanced decoder capabilities, additional bits received via one or more enhancement layers permit encoded video to be reconstructed with increased spatial resolution and continuously improved video quality across different spatial resolutions. The techniques permit spatial scalability layers to be coded as FGS layers, rather than discrete layers, permitting arbitrary scalability. <P>COPYRIGHT: (C)2013,JPO&INPIT
