[Mp4-tech] [Video: mpeg-4.2] profiles level questions.

[Grigory A.]

Hi!
Could some one help me?
Me question is following:
Annex N of mpeg-4.2 describes "Visual profiles levels"
so
does it means SP L1 can have up to 4 VO?
and if answer is "yes" - how these 4 VO are combined on final scene?
or if I am wrong - what does is the meaning of "4" in column
"Max ob-jects" in this annex?

Best wishes,
Grigory A.
