MPEG-5 Essential Video Coding (EVC) is a current video compression standard (ISO/IEC CD 23094-1) that was completed in April 2020. The standard is to consist of a royalty-free subset of coding tools and individually switchable enhancements.
EVC has a lower number of coding tools than VVC, and only a few especial like that:
- AMIS is the advanced motion signaling and interpolation;
- IQT is the improved quantization and transform;
- HTDF is the hadamard transform domain filter.
The goal of MPEG-5 EVC is to provide a standardized video coding solution to address business needs in some use cases, such as video streaming. The baseline profile includes only technologies that are more than 20 years old or that were submitted with a royalty-free declaration. The main profile adds a small number of additional tools that each provide a significant improvement in terms of compression performance and have its own license. The coding performance of the Baseline profile is better than H264(AVC) and the Main profile is better than H265(HEVC).
The EVC codec is based on the tools & technologies proposed by Qualcomm, Samsung, and Huawei and the reference picture management and other high-level syntax aspects proposed by Divideon.
