Closing Audio Plenary and meeting deliverables

1. Plenary discussions

Impact of limited expert participation at the 92^nd meeting

The Chair indicated that the following CEs will be taken up as the first item of business at the 93^rd MPEG meeting

• 
  FhG/Samsung arithmetic coding of spectral coeoefficients
  
• 
  Dolby/Philips downmix/upmix
  

As the first item of business at the 93^rd meeting the Chair will ask for a decision on acceptance of the CEs as if it were at 92^nd meeting (but now with all experts present). In other words, decisions based on information available at the 92^nd meeting. The Chair further noted that there would be no need for additional contributions on the CE from the CE proponents, and no contributions to the 93^rd meeting will be reviewed prior to making the decision.

However, specifically concerning the FhG/Samsung CE, the CE proponents have the option of asking the Audio subgroup to postpone the decision on the CE until other relevant contributions to the 93^rd meeting have been reviewed.

New ideas in coding and subjective evaluation

Vittorio Barronchini, Test Chair, noted that he has great interest in and expect to submit a contribution to the 93^rd meeting on:

• 
  Evaluation of joint audio/video coding and bit allocation, and would be most interested in the opinion of audio experts on this topic.
  
• 
  Test methodologies that go beyond mean opinion score responses.
