GUIDING PRINCIPLES FOR THE SINGAPORE MEETING


The sub-group expressed some requests regarding the Test Model TM0 that 
should be issued at the Singapore meeting.

1)	The Test Model should be very simple at the beginning and be improved 
by including elements which have been verified.

2)	Some room should be provided within TM0 to allow the optimization of 
the low delay mode.  

Note:	End to end delay must be clearly defined for

    -	forward field prediction
    -	forward frame prediction
    -	forward and backward prediction, use of B-frames.

3)	A proposed core experiment should allow backward/forward 
compatibility with MPEG1 or H.261 (as embedded bitstream at 1.15 Mbit/s) 
and comparison with simulcast modes.

4)	TM0 should provide sufficient room to implement schemes with forward 
prediction only in the interest of low delay and simple 
implementation.

5)	Scalability and effectiveness of the coding schemes at low bit rates 
are important items.

The sub-group also agreed that the Experts group should make a proposal to 
specify a cell loss experiment, and particularly describe the simulation 
environment for cell loss resilience comparison.
