Information technology - Coding of audio-visual objects - Part 2: Visual AMENDMENT 1: Error resilient simple scalable profile

In ISO/IEC 14496-2:2004, the bitstream syntax of the Simple Scalable Profile does not allow the use of the error resilience tools. As the enhancement layer can only be decoded if it is received error-free this limits the use of scalable video to error-free communication environments. This would exclude mobile communications, a significant future market for MPEG-4 SSP.
Scalable video can be quite useful in many other applications. For instance, matching different or varying network bandwidths, video multicast to heterogeneous end systems and more importantly, providing different subjective quality of video content to subscribers of a given video service depending on their network tariffs and viewing preferences.
As such, ISO/IEC has defined the addition of an MPEG-4 Error Resilient Simple Scalable Profile. This Amendment describes the technical changes for this profile.
In addition, the new Level 0b is added to the MPEG-4 Simple Visual Profile and the amendments are described in this Amendment.
