MPEG-5 Essential Video Coding (EVC) is a future video compression standard that is expected to be completed in 2020. The standard is to consist of a royalty-free subset and individually switchable enhancements.
The publicly available requirement document outlines a development process that is defensive against patent threats: Two sets of coding tools, base and enhanced, are defined:
- The base consist of tools that were made public more than 20 years ago or for which a Type 1 declaration is received. Type 1, or option 1, is ISO speak for royalty-free.
- Tools in the enhanced set must pass an extra compression efficiency justification and be possible to disable individually.
Bitstream-switchable coding tools are also known from Divideon's XVC.

I saw the danger coming and designed a strategy for it. This would create two tracks in MPEG: one track producing royalty free standards (Option 1, in ISO language) and the other the traditional Fair Reasonable and Non Discriminatory (FRAND) standards (Option 2, in ISO language).

Though the EVC Main profile uses royalty-bearing “tools,” these can be switched on and off with “limited loss of performance.” This was the model deployed by Divideon and their xvc codec, and, in theory, it allows those deploying the technology to pick and choose both the performance and the associated royalty cost. (…) Two proposals were submitted in response to MPEG’s call for proposals for MPEG-5 Part 1, and MPEG selected the proposal from Samsung, Huawei, and Qualcomm
