| USAC Spectral CE
The Chair re-opened the discussion on the FhG/Samsung arithmetic coding of spectral coefficients CE and asked if there was objection to making a decision at this time. Two experts voiced an objection to a decision now, and cited that the syntax and semantics for this CE was only available Wednesday (GMT) of the MPEG week.
The Chair noted that there was not consensus in the Audio subgroup to make a decision on this CE. The Chair informed the group that he will call for a decision on this CE as the first item of business in Audio plenary at the 92nd MPEG meeting.
Evaluation of USAC CEs
The Chair re-iterated the importance of developing an overview of USAC CEs to assist in evaluating the technical merit of all CEs in a fair and transparent manner. This is the most important AhG activity!
Timeline for USAC standardization
The Chair charged the Audio subgroup to consider whether it is likely that future USAC CEs might make significant changes in the USAC architecture. If this were to be the case, then it might be premature to take USAC to CE at the next meeting. The timeline for the USAC work will be revisited at the 92nd meeting.
