[Mp4-tech] MPEG4 encoders with ability to segment VO from theinputvideo stream

[Paco Gomez]

Ian,
Thanks for your answer. If the use of VO is not the essential part for the
incredibly much better compression quality achieved by MPEG4 as compared to
MPEG1/MPEG2, what are the key factors (if there are key factors at all and
it is not an addition of different small factors) which make MPEG4/2 so much
better in compressing a video sequence?
Is there any paper or book discussing this topic in more detail?
BR,
Paco Gomez

I'm not aware of any encoders on the market that can do this (but would be
very interested if there is anything out there !)

inputvideo stream
Hello,
I am new to the list, thus my apologies if I ask something very obvious or
already explained.
My question is as follows. MPEG4 standard defines VO as different objects
that are encoded separately. This is easy to understand if the video
source(s) are already delivering the VO separated (as it could be the case
in a TV studio). However, in the usual case in which a unique video signal
is presented at the encoder input, the encoder itself would have to segment
the image to find the VO present in the scene. My question is:
Is there available in the market any MPEG4 encoders with the ability to
segment VO in a scene? Is this a common feature?
Thanks in advance.
