Abstract

Low Complexity Enhancement Video Coding (LCEVC) is a new MPEG video codec, currently undergoing standardization as MPEG-5 Part 2. Rather than being another video codec, LCEVC enhances any other codec (e.g. AVC, VP9, HEVC, AV1, EVC or VVC) to produce a reduced computational load and a compression efficiency higher than what is achievable by the enhanced codec used alone for a given resolution, especially at video delivery relevant bitrates. The core idea is to use a conventional video codec as a base codec at a lower resolution and reconstruct a full resolution video by combining the decoded low-resolution video with up to two enhancement sub-layers of residuals encoded with specialized low-complexity coding tools.
