HI,

The response to my query on MULTIMEDIA SYNCH was very poor. The number
of people interested in the summary far exceeded the number of responses
Anyway, here is the summary of whatever little I got.

My Comments :

The above two are very good schemes for controlling real-time
packet delay and jitter. But they do not deal with MULTIMEDIA 
SYNCHRONIZATION at a process interaction under a FORMAL SEMANTIC 
model.

My Comments :

I dont have access to these. Can anybody please give me any pointers
to its availability ?

My Comments :

Have not yet received the above document. Cant comment on its usefulness.
