Dear Angus,
Dear Olivier,
All,

We at Philips, have been working on applications requirement
(among them set-top boxes was of our interest) to describe
the newly accepted profiles in MPEG-4. For us the most
appropriate profiles are the Core2D Scene graph and Graphics
profiles.

On this point I agree to waht is said by Olivier.

Again, we at Philips support and implemement the Core 2D profiles
for STB related applications (and others).
For more advanced features the usage of the Advanced 2D profiles can
be considered.
For more details have a look to the following MPEG document
from Sydney meeting : w4268 (sections 18 & 19)
Best regards,
Laurent.
