A. Mason discussed an update to his work on lip sync for HDTV.
There are two areas of interest. One is the human sensitivity to the time alignment between audio and video. The second is concerned with a technical method of measurement of audio to video time alignment (AV sync).
Many groups are looking at AV sync, including SMPTE, EBU, ITU, and HDMI. Should the AES be involved with defining a AV sync measurement method? The meeting felt that the answer was a clear "yes".
It was decided to propose a new project for AV sync. Mason will write a project scope and complete a new project proposal form.analog measurements
Is there any scope for analog measurements - do they belong in SC-02-01? This will be discussed by AESSC as part of an expected general reorganisation of the standards working groups.
The next meeting of SC-02-01 will be scheduled in conjunction with the AES 124th Convention in Amsterdam, 2008-05.
