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 second meeting during 21-28 July, 2010 at the itu-t premises in Geneva, ch

8.2Common conditions for testing

Common conditions for experiment testing were selected by the group and described in output document JCTVC-B300.

8.3TE1 Decoder-side Motion Vector Derivation

Continuation of a similar prior TE, coordinated by Mathias Wien (RWTH), summarized as follows:

• 
  Implementation in TMuC
  
• 
  6 proposals included
  

• 
  2 sub-experiments: Inter prediction, direct mode
  
• 
  Try to explore interdependency with TMuC tools
  
• 
  Only high complexity configuration
  

8.4TE2 IBDI and memory compression (old TE2)

Continuation of the prior TE on memory compression, coordinated by Takeshi Chujoh (Toshiba), with additional emphasis on:

• 
  Sizes of access units (should be comparable, and idea about the overhead that comes due to overlaps in random access)
  
• 
  In which parts of the codec is IBDI necessary – only for processing, or also for storage?
  
• 
  Due to the need for fixed bit rate per access unit, subjective impairments may appear locally
  -> subjective investigation needed.
  
• 
  Complexity investigation of different methods
  
• 
  Is built-in spatial scalability useful e.g. for power saving?
  

Some discussed aspects:

• 
  Implementation in TMuC
  
• 
  Use BD rate/PSNR computation interpolation mode 3 (default).
  
• 
  Also measure the distortion per access block (in order to identify whether there are unusually high distortions locally).
  

An AHG will study related issues beyond the scope of the TE (e.g. relation with MC etc.).
