JVET software


JVET was founded as the Joint Video Exploration Team (on Future Video coding) of ITU-T VCEG and ISO/IEC MPEG in October 2015. After a successful call for proposals, it transitioned into the Joint Video Experts Team (also abbreviated to JVET) in April 2018 with the task to develop a new video coding standard.

The new video coding standard was named Versatile Video Coding (VVC).

Reference software

The reference software for VVC is the VVC Test Model (VTM).

VVC Test Model (VTM)

The VVC reference software was started with a minimal set of coding tools. Additional tools will be added after testing in Core Experiments (CEs).

Other software

Benchmark Set (BMS)

The Benchmark Set (BMS) software was created for additional testing of proposed tools in a framework that is more feature-rich than VTM. BMS contains tools that were originally proposed in the JEM software.

The BMS software has no official status.

Joint Exploration Model (JEM) - Discontinued

JEM is the experimental software of the Joint Video Exploration Team, which contains coding tools that were studied for achieving coding performance beyond HEVC.

The software effort was originally started by VCEG under the name HM KTA. The software repository therefore contains some version tags using the old KTA name. Recent versions are tagged under the newer name JEM. The JEM software is based on the HEVC Model (HM) software that was jointly developed as reference software for the HEVC standard.

The JEM software is no longer maintained. VTM is the official VVC reference software.
