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 are also known from Divideon's XVC.[6]

Contributors

A proposal by Samsung, Huawei and Qualcomm was selected as the basis for EVC.[6] Divideon is among the editors of the standard.[7]

gollark: It's derived from the Notenglish word "argleflargleblargleasdasofaaaragamovovoeasd", meaning "old image format with many poor features only used due to the fact that it is commonly played animated even if considered an image".
gollark: "GIF" is more correctly pronounced "argleflargleblargleasdasof".

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.
