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

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. -- Matthew Donadio (m.p.donadio@ieee.org)

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
