Summary report (4 proposals submitted):

• 
  Samsung proposed a distortion function for R-D mode decisions.
  
• 
  HHI described view synthesis optimization.
  
• 
  LG suggested a modified depth distortion measure.
  
• 
  Zhejiang described joint RDO for depth coding.
  

"Virtual gains" were reported due to different rate allocations; however, better understanding was needed. It was noted that optimization towards PSNR of synthesized views allocates more bit rate to depth, and there was a suggestion of testing with a fixed texture bit rate and a changing depth rate It was suggested to refine the CE in order to provide viewing results at the same bit rates.

Conclusions:

• 
  Add an option for m23714 in the software.
  
• 
  Continue CE.
