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-B007 [T. Yamakage, Y. J. Chiu, M. Narroschke, X. Wang (chairs)] AHG report: In-loop filtering

This document summarized the In-loop Filtering ad hoc group activities between the 1^st JCT-VC meeting in Dresden, Germany (15 to 23 April, 2010) and the 2^nd JCT-VC meeting in Geneva, Switzerland (21 to 28 July, 2010).

Several types of in-loop filters were investigated: Wiener-based, De-blocking/de-banding, Nonlinear (e.g. codeword restriction).

During the presentation of the report, the following issues were raised and discussed:

• 
  In-loop filtering also needs investigation of subjective quality – how to arrange this?
  
• 
  Levels of complexity of the different methods are quite diverse.
  
• 
  It is necessary to combine this with an investigation of the TMuC design overall.
  

JCTVC-B008 [K. Panusopone, M. Budagavi, D. He (chairs)] AHG report: Large block structures

This document summarized the Large Block Structures ad hoc group activities between the 1^st JCT-VC meeting in Dresden, Germany (15 to 23 April, 2010) and the 2^nd JCT-VC meeting in Geneva, Switzerland (21 to 28 July, 2010).

The methods can be classified as "extended macroblock schemes" and "flexible quadtree schemes".

During the discussion, several participants raise their opinion that large structures could have impact on implementation complexity
