Essential Video Coding – licence friendly baseline
EVC is intended to be an alternative to coding standards such as HEVC, AV1 or VVC and expressly designed to be royalty free in its basic implementation. It was initiated by MPEG as a countermeasure to the opaque licencing costs of HEVC by being offered in two profiles.

Low Complexity Video Coding – codec agnostic
Despite being part of the same MPEG 5 family there is no connection between EVC and LCEVC. It’s a fundamentally different approach to EVC in which the solution relies on taking an existing codec available in hardware – which could be AVC, HEVC or, in future, VVC - and adds a software layer on top responsible for improving the performance of the hardware encoder.

Versatile Video Codec on track
VVC is on track to be finalised as an international standard by the end of 2020. The next-generation (after HEVC) standards-based codec developed jointly by MPEG and the ITU targets 30% bitrate reduction over HEVC at the same perpetual quality. Trials, including by BBC R&D, confirm this. VVC capabilities are expected to support immersive content, resolutions from 4K to 16K and 360° videos particularly in complement to 5G networks.
