OPTIMIX standardisation effort


Standardisation effort purpose

The ICT OPTIMIX project was expected to produce innovative solutions in several areas, in particular in the domains of video coding and networking. The developed new schemes were in particular meant to be exploited for contributions to international standards. Especially the work on high compression-efficient and high quality video codecs was used in the context of standardisation at the relevant bodies (i.e., ISO/IEC MPEG and ITU-T VCEG, and its joint group JCT-VC). The following list gives an overview of the standardization groups targeted by the OPTIMIX project.

Video Coding Experts Group (VCEG)

  • At the start of the OPTIMIX project, VCEG investigated on new tools for coding efficiency. In order to compare the results of the different tools, VCEG therefore established a joint software platform (i.e., the KTA software) to integrate well performing proposals. In addition, VCEG continued to work on the requirements for a potential new video standard (i.e., "H.265"). These activities resulted into a standardisation project named High Efficiency Video Coding (HEVC), which is executed jointly with MPEG in the JCT-VC (see below).

Moving Picture Expert Group (MPEG)

  • At the start of the OPTIMIX project, MPEG ran an exploration on New Challenges in Video Coding Standardization. This resulted in the development of a new video coding standard (i.e., HEVC). The requirements set by this group are similar to those defined by VCEG.

Joint Video Team (JVT)

  • The JVT is a joint group of MPEG and VCEG. In the past, it served as the working group for the standardisation of H.264/AVC and its Scalable Video Coding (SVC) extension (Annex G of H.264/AVC). OPTIMIX contributed to the JVT on the SVC reference software (i.e., JSVM) [1].

Joint Collaborative Team on Video Coding (JCT-VC)

  • Like the JVT, the JCT-VC is also a joint group of MPEG and VCEG. The JCT-VC was established in April 2010, when it had its first meeting in Dresden, where experts from MPEG and VCEG participated. It is currently working on the standardization project on High Efficiency Video Coding (HEVC). HEVC can be seen as the successor of the H.264/AVC standard. The goal for HEVC is the improvement of compression efficiency by 50%. OPTIMIX contributed to the JCT-VC [2][3].

Internet Engineering Task Force (IETF)

  • Within IETF, especially its work on RTP transmission is relevant for the OPTIMIX project. Currently (after the finalization of the RTP payload format for SVC), no future standardization topics for OPTIMIX are seen within IETF.
