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-B116 [M. Karczewicz, R. Panchal, P. Chen (Qualcomm)] TMuC performance evaluation

This contribution focuses on coding efficiency evaluation of TMuC 0.4. The average improvement of TMuC 0.4 over TMuC 0.1 obtained using the best combination of tools is 7.1% for the IPPP configuration.

Note: 2.5% out of the gain is caused by switching off early termination of the skip mode decision.

It was remarked that in general the RD optimization of current TMuC combination certainly requires more study.

Currently no investigation of the TMuC exists on a tool by tool basis.

Qualcomm indicated that they could provide their detailed results (including some tool by tool analysis) as a late contribution. An update of the software AHG report included results for both IPPP and hierarchical B cases.

JCTVC-B101 [G. Clare, J. Jung, S. Pateux (Orange Labs)] Preliminary results on motion vector prediction

This contribution provided some preliminary results on motion vector prediction in the TMuC. It is suggested to launch a Tool Experiment on the subject.

Comparison of interleaved MV prediction and MV competition was performed. It is reported that MV competition alone has highest performance (approx. 1.3% better than combination with IMVP).
