ISO/IEC 23002-5:2017 describes: - what is meant by conformance of what is specified in ISO/IEC 23002-4, - the structure of the reference software related to what is specified in ISO/IEC 23002-4. Currently the following profiles are included in ISO/IEC 23002-4 and in this document as reference software: - ISO/IEC 14496-2 Simple Profile, - ISO/IEC 14496-10 Constrained Baseline Profile, - ISO/IEC 14496-10 Progressive High Profile, - ISO/IEC 14496-16 SC3DMC, and - ISO/IEC 23008-2 Main Profile. NOTE The reference software supports the decoding of bitstreams that conform to the Main Profile of ISO/IEC 23008-2, but does not support display-related features indicated in supplemental enhancement information (the support for which is a display capability that is outside the scope of ISO/IEC 23008-2).
