ADT PICOVIN-P

Participants : Laurent Guillo [contact person] , Thomas Guionnet.

The ADT Picovin-P is a technological development action, which works closely with the project-team SIROCCO. This development structure is the follow-up of the ADT Picovin. It gives its support to the project-team to integrate new and relevant algorithms into the state-of-the-art video codec and to take part in standardization.

During this year, the ADT first pursued its developments on Intra prediction in the context of the standardization initiative referred to as High Efficiency Video Coding (HEVC) and led by the Joint ITU/MPEG Collaborative Team on Video Coding (JCT-VC). HEVC is implemented as a test model, the HEVC test Model (HM) in which the ADT tools have been integrated. We then followed the standardization activities within the Joint Collaborative Team on 3D Video Coding Extension (JCT-3V). JCT-VC and JCT-3V have been both created by the ITU-T Study Group 16 (VCEG) and the ISO/IEC JTC 1/SC 29/WG 11 (MPEG). While JCT-VC aims at developing a new generation 2D video coding standard, JCT-3V aims at developing 3D extensions for video codecs, which are AVC (ATM) or HEVC (HTM) based.

As part of JCT-3V, we submitted several proposals related to the handling of the merge list of predictor candidates. They were about the re-ordering of the candidates in the list and about the addition of new candidates. Two of them have been accepted in the dedicated core experiment (CE) during the 1st JCT-3V meeting which was held in Stockholm in July 2012. An improved version related to the addition of candidates has been accepted in a CE during the 2nd JCT-3V meeting in Shanghai in October 2012. It will be integrated in the coming test model (HTM) and evaluated during the next meeting in Geneva in January 2013. During 2012, the ADT also took part in cross checks which aims at evaluating and testing tools studied in core experiments. As part of cross checks related to JCT-VC or JCT-3V the ADT ran 9 tests jointly with companies such as Canon, Huawei, HiSilicon and Nokia. The ADT Picovin-P started in October 2011 and lasted one year. During this year, one permanent engineer from the SED Rennes (development and experimentation department of Inria Rennes) and one senior engineer specialized in video compression are involved in the ADT. It is supported by the technological development department of Inria.
