The ADT Picovin is a technological development action, which works closely with the project-team TEMICS. This new development structure gives its support to the project-team to carry out a new and efficient video codec. This support is twofold. The project-team TEMICS provides the ADT with innovative algorithms that are first adapted and integrated in the current codec. Then the resulting codec is evaluated thanks to a large base of videos in order to measure how significant these new contributions are and to detect as soon as possible unexpected behaviour. Hence, step by step, the emerging new codec performs better and better. Throughout this process, it is compared with the still evolving competing video codecs, for instance JM and KTA.

In April 2009, the ISO/MPEG working group issued a call for evidence with the expectation that responses would report the existence of technologies that would be able to efficiently take into account new challenges in video coding such as ultra high definition (e.g. 4Kx2K displays). Responses were reviewed during the 89th MPEG meeting in London in July 2009. Significant improvements were achieved and a call for proposal will be probably issued in October 2009 during the 90th MPEG meeting in Xian, China.

The ADT Picovin aims at providing a video codec that meets the requirements, or a significant subset, of the coming call for proposal. In 2009, we focused on the integration of algorithms, which significantly improved spatial and temporal predictions, and the development of an evaluation platform, which can cope with very demanding test conditions. This new development structure started in October 2008 and will last three years. Three junior engineers and one permanent engineer from the SED Rennes (development and experimentation department of INRIA Rennes) take part to the ADT. It is supported by the technological development department of INRIA.
