Call
---------------------------------------

1) PVS generation
   HD1 : Status has to be re-checked, see email by Matthias regarding hashes problem
   HD2 : Status has to be re-checked

   --> Silvio will ask Dejan about the status of HD1 HD2. 

   WVGA1 : some files in different 4:2:2 file format.    
     Converted by Chulhee in dropbox.
     Converted by Vittorio, there are some small differences. 
     --> Chulhee will check the differences, once Vittorio has uploaded them.
   
     --> Silvio will ask Vittorio to bring his version of WVGA1 to the meeting.
   
   FFmpeg decoder (as part of definitely lossless): puts wrong number of frames in the header (e.g. 260 instead of 300).
   --> Roland will try to compile a list of files having this problem.
   

2) Subjective testing

   HD3: 29 subjects in total (at least 5 "outliers", 3 subjects not checked yet).
        Some references have relatively low score. To be discussed at the meeting.

   VGA1, VGA3, HD5, : in progress, hope to finish this week
   
   WVGA1: ready

   VGA2: ready

   HD04: should be finished by end of week

   
   

3) Model change proposal by SwissQual and DT.
   See email sent by Margaret (Mon 17/06/13).
   
   Opinion of Opticom: Should be discussed at the meeting.
