The Joint Collaborative Team on Video Coding (jct-vc) of itu-t wp3/16 and iso/iec jtc 1/sc 29/wg 11 held its second meeting during 21-28 July, 2010 at the itu-t premises in Geneva, ch

JCTVC-B053 [A. Krutz, T. Sikora (Tech. Univ. Berlin)] Summary report for TE3 on inter prediction in HEVC

This document summarized the activity of TE3. TE3 included activities on two subtests. Subtest 1 investigated parametric motion compensation. Subtest 2 is about flexible motion partitioning. For subtest1, two participants (LG, TUB) had conducted experiments and reported a significant improvement from these tools. Additionally, one related document from NCTU presented new results on MB Mode with joint application of template and block motion compensations. Three participants of subtest 2 (Technicolor, Huawei, Qualcomm) had contributed experimental results and reported further improvement of coding efficiency and computational cost on flexible motion partitioning. Overall the TE3 activity had made a significant progress regarding the proposed technologies.

It was remarked that parametric MC appears not to give significant gain for the CfP set, but reportedly does for some additional sequences selected by contributors.

Summary of status for TE4 on variable length coding

For TE4 (variable-length coding), no summary report was provided. These experiments did not show much activity. It was argued that the original planned test conditions were hard to pursue when considering the state of development of the TMuC software.

In this context, it was mentioned that in principle the original TENTM (JCTVC-A119) approach (grouping syntax elements together) can also be applied in the TMuC context, but this would take more time for integration before it can be properly tested.
