10、rotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of techni
11、cal activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technic
12、al committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circ
13、ulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

15、96-4:06ISO/IEC 14496-4:2004/Amd.5:2005(E) iv ISO/IEC 2005 All rights reservedIntroduction 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
16、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 multic
17、ast 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 a set of bitstreams which should be used for conformance testing of MPEG-4 Error
18、Resilient Simple Scalable Profile is proposed.
