RE: [M4IF Technotes] Re: [M4IF News] MPEG special in EE TimesOlivier,
friends and comrades,
I didn't talk about MPEG-4 only STB. I anticipate that there will be STB
that include MPEG-2 next MPEG-4 features.
Which of the two standards will be used more ? I don't know, you may know
better.
Klaus

  Dear Klaus, all,
    don't get me wrong, I don't intend to handle backward compatibility.
This is not my agenda. I don't even build set-top boxes.
    I only talked to people who are discussing those issues. The conclusion
for use of technology within a STB may be influenced by
    a number of arguments, some of them are more of a marketing character.
    Again, this is not my position, but I learn about the existence of those
positions, and I thought that I should share that with you.
    It is interesting to push the idea to its limit. So I am interested to
learn what people can win by having MPEG-4 only STB. Video quality ? At high
bitrates, I am not sure it is worth it, but I am interested to learn more
about this. What else ? It is on the contrary very clear what will be lost :
backward compatibility, costs development for production tools, duplication
of encoded content or encoding costs, ...
    It is much more interesting to construct the architecture of the STB
backward compatible with MPEG-2 and with MPEG-4 as a new media that goes on
top/along with/aside of MPEG-2 content.
    Kind regards,
    Olivier
