4. Common set: status

5. Other  




Call:
----------------


1. Source scene pool:
      
   Chulhee: Data analysis by Yonsei, see email. Result: average MOS scores of HD05 are quite
   high, but for VGA, WVGA are quite low.

   Savvas proposal: keep sources, lower bitrate for HD.

   --> For VGA02, WVGA01 increase bitrates

   For HD, 4 replacements are proposed, but 2 are progressive:
   --> Margaret has more HD sources. Chulhee will propose, which sources should
   be replaced. Margaret will then propose replacements.


2. Test vectors:
   no status update


3. PVS generation:

   HD01 : ready for upload
   HD02 : ready for upload
   HD03 : ready for upload
   HD04 : will be uploaded by next audio call
   HD05 : wait on sources to be replaced
   HD06 : processing

   VGA01 : ready for upload
   VGA02 : bitrates will be adjusted
   VGA03 : PVS generation progressing
   
   WVGA01 : bitrates will be adjusted
   WVGA02 : still problems to produce rebuffering

   


4. Common set:
   
   For 2 HD sequences src2,src3 wrong encoding parameters were selected.
   --> For these 2 sequences, use the avi files instead of h264-lossless encoded files.
