Yep.
The MPEG-4 format is so broad that you
can do almost everything.

Hi Matthew,
Unfortunately I do not know any profiles and codecs at the moment. If
it helps, the MPEG-2 streams contain digital TV which I want to
convert as a single AV-Object into MPEG-4. I want to offer my
customers a MPEG-4 based menu so that my customers can select among
several TV channels and Video (near) oon-demand streams or games etc.
Thanks, best regards,
Herbert

You will have to be a heck of a lot more specific.
Audio or video or both?
If audio, which spec(s) and layers?
If video, which profiles and levels?
What systems layer(s) for MPEG-2? None? Program stream? Transport stream?
What part of the MPEG-4 spec is the target?
Realtime or not?
I know more about MPEG-1 and -2 than -4, so there are probably more issues
for MPEG-4.

Hi,
as mentioned in the subject line, I am looking for a MPEG-2 to MPEG-4
converter, which is implemented in hardware. AFAIK, only
software-based solutions are available.
Thanks for any help,
Herbert
