JCTVC-M0449 BoG Report on reference layer sample location derivation in SHVC [J. Chen (BoG coordinator)]

For the reference layer sample location derivation used for syntax prediction, the BoG recommended to the method from JCTVC-M0133 with shift bit equal to 16.

For the reference layer sample location derivation used in the resampling process, the BoG recommended the following:

• 
  To adopt the method mentioned in section 2.2 of the BoG report, which is the method used in the current software, as proposed in JCTVC-M0188, JCTVC-M0322 and JCTVC-M0425 (not the entire proposals, but this element of them).
  
• 
  Further study is needed on whether higher accuracy, larger shift bit, is needed.
  
• 
  Suggest cleaning up the related software code sections containing the division operation which is disabled by default in the current SHM software.
  

(See additional comments in BoG report.)

Further discussed –ion was chaired by J. Boyce.

Decision: Adopt the solution described above, as recommended by the BoG.
