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 tenth meeting during 11-20 July 2012 at the City Conference Centre (ccc), a k. a

JCTVC-J0350 AHG5/AHG6: Cross-verification of JCTVC-J0148 on bypass coding for SAO syntax elements [K. Chono, K. Tokumitsu (NEC)] [late]
JCTVC-J0347 AHG6/AHG5: Simplified SAO coding [I. S. Chong, J. Sole, M. Karczewicz (Qualcomm)]

In HM-7.0, each LCU has one set of SAO signaling for each color component. Each set of SAO signalling includes merge signals (i.e., merge_up and merge_left) and if merge signals are not used, new set of SAO syntax (i.e., sao_type_idx, sao_offset_abs, sao_offset_sign, and sao_band_position) is sent to the decoder. In this proposal, we propose to simplify above SAO signaling, especially for merge flags, sao_type_idx. Results reportedly show 0.0%/0.3%/0.3%/0.4% luma coding gains for Main-AI/RA/LB/LP, respectively. We further propose to simplify sao_offset_abs coding. Results reportedly show 0.0%/0.3%/0.3%/0.3% luma coding gains for Main-AI/RA/LB/LP, respectively.

According to proponents, this has already been discussed in context of other proposals (it is a combination of J0103, J0104, J0106/J0043, J0041) – no need for presentation.
JCTVC-J0422 Cross-check of AHG6/AHG5: Simplified SAO coding (J0347) by Qualcomm and Mediatek [C. Rosewarne, M. Maeda (Canon)] [late]
Candidates for adoption were considered:

J0041

J0043

J0046=J0054

J0268

J0355

J0045 (pending on benefit in combination with J0355)

• 
  Test combination of J0355 and J0045 as said elsewhere
  
• 
  J0045 would have benefit implementation-wise
  
• 
  Provide combined text
  

For the first 4 items (can be done in parallel with previous):

• 
  integrate text and software
  

Afterwards: Provide a combined text and result for all candidates combined.
