Standards: Appendix K - Publicly Available Standards

Here is a list which shows whether each of the 34 parts of the MPEG-4 standard is publicly available.

This is an Appendix to our series of articles on Standards.

Once a standard is published, you can purchase it from the ISO online store. Amendments and corrigenda will need to purchased separately. Some Publicly Available Standards (PAS) are free of charge. Download them from the Information Technology Task Force (ITTF) web site here:

https://standards.iso.org/ittf/PubliclyAvailableStandards/index.html

The following MPEG-4 parts are available under the PAS scheme:

Part	Title
4	Conformance testing bitstreams
5	Reference software
7	Reference Software for A/V Objects
10	AVC
20	LASeR (Lightweight scene description)
22	Open font format
26	Audio Conformance testing
27	3D Graphics conformance testing
28	Composite font representation
32	File format reference software and conformance

PAS means that the standards documents are freely available but this does not mean they are free of patent encumbrances. You may still need to pay license fees.
