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.
