Description (English):

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).

Abstract

Overview

ISO/IEC 23002-5:2017 - part of the MPEG video technologies family - specifies the conformance rules and reference software structure for the Reconfigurable Media Coding (RMC) framework. The standard explains what conformance means for the video tool library defined in ISO/IEC 23002-4, and documents the composition and use of the RMC reference software (RMC Simulation Model). It includes reference implementations for several existing codec profiles so implementers can validate decoders against normative test bitstreams.

Key topics

Conformance definition and procedure
- Conformance of an RMC decoder is demonstrated by instantiating Functional Units (FUs) from the media tool library into an Abstract Decoder Model (ADM), decoding standardized conformance bitstreams and comparing outputs to the uncompressed reference sequences specified in ISO/IEC 14496-4.
Reference software structure (RMC Simulation Model)
- Components described include: Bitstream Syntax Description (RVC‑BSDL), FU Network Description (FNL), Abstract Decoder Model (ADM), Video Toolbox Library (VTL), model instantiation tools and the parser generation process.
- Implementation artifacts and languages referenced: RVC-CAL (FUs), XDF (networks), and conversion pathways to C/C++/Java or HDL for implementations.
Profiles covered by the reference software
- Implementations and conformance data are provided for:
  - ISO/IEC 14496-2 Simple Profile (MPEG‑4 Part 2 SP)
  - ISO/IEC 14496-10 Constrained Baseline Profile (AVC CBP)
  - ISO/IEC 14496-10 Progressive High Profile (AVC PHP)
  - ISO/IEC 14496-16 SC3DMC
  - ISO/IEC 23008-2 Main Profile (reference software decodes Main Profile bitstreams but excludes display-specific SEI features)
Test vectors and build guidance
- Conformance bitstreams are taken from ISO/IEC 14496-4 and the standard includes an Annex describing how to compile and use the reference software. Reference files and electronic attachments are available from the ISO online repository.

Applications and who uses it

Codec and decoder implementers - use the RMC reference software and conformance procedures to validate that an implementation reproduces the standardized decoded output.
Conformance and interoperability labs - run standardized bitstreams and comparisons for certification and interoperability testing.
Chipset vendors and SDK providers - translate ADM descriptions into optimized C/C++ or hardware implementations.
Researchers and tool developers - leverage the modular media tool library (FUs) for prototyping and experimentation with reconfigurable codec architectures.
