Essential Video Coding
MPEG-5 Essential Video Coding (EVC) is a future video compression standard that is expected to be completed in 2020.[1][2][3] The standard is to consist of a royalty-free subset and individually switchable enhancements.[2][3][4]
Concept
The publicly available requirement document[4] 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.[5]
- Tools in the enhanced set must pass an extra compression efficiency justification and be possible to disable individually. Bitstream-switchable coding tools is also known from Divideon's XVC.
