[M4IF Technotes] max size in simple profile

[anuradha]

Hi,
I am trying to encode a frame of arbitrary size, greater than CIF using
Simple Profile. Short Video Header format
doesn't allow me to use arbitary sizes( Table 6.25 in visual standard ).
     Can I achieve this by using 4 Vidoe Objects each of size less than or
equal to CIF?
In simple Profile L3, if I use 4 Video Objects, then what is the Maximun
total area of 4 Video Object Planes? Is it 396x4
macroblocks or just 396 macroblocks ?
Thanks
Regards
Anuradha

Hi
If you are decoding a dingle VO in simple profile level-3, then you can
decode any frame, which has total number of macroblocks <= 396 (e.g., a
frame of size 640x144).
Furthermore, Max. VMV buffer size of 792 and VCV decoder rate of 11880 have
to be satisfied.

Hi,
Can someone help me with the maximum frame size supported by simple profile?
The standard says, "typical session size" as
CIF for level3. Does it mean I cant encode any frame larger than CIF( 352 x
288 x 30 ) using simple profile?
