[Mp4-tech] [System]Audio video sync

[Bharat P. SONI]

Hi,
Just few inputs!!
In the first proposal there is possibility of slight 
inaccurecy, but it may be acceptable. 
Second proposal seems to be more deterministic in nature as 
the interrupt from audio renderer have very high prioroty so 
you can update the system time here quite accurately. The 
problem I see is if due to some reason we are not able to 
send enough data to the audio renderer (may be due to data 
loss in the network) will this interrupt be called on time? 
If not then we will have incorrect system time.
Another problem (also related to the problem above) is that 
in this case the system time is dependent on the audio. For 
presentatin that may not have audio, your system have no 
other option for clock.
Regards,
Bharat
