[opendtv] Re: TANDBERG launch MPEG-2 Broadcast Encoder

FYI, it's not just ATSC.  The Metropolitan Opera uses MPEG-2 in its transmissions to movie theaters worldwide.  We started that way due to receiver availability, but one reason we are continuing is that we are able to use multi-language HD subtitle inserters that work within the compressed MPEG-2 stream, allowing us to have just a single bit-rate-reduction stage (no concatenation) all the way from our cameras to the cinema screens.

TTFN,
Mark

MPEG-2 is no longer state of the art and probably mature enough only
very marginal improvements may now be made.  However since ATSC will
still be using it for quite awhile I'm glad that Tandberg at least is
still working on improving their implementation of it.  There are
probably a still bunch of stations out there using very early and
inefficient real time MPEG-2 encoders that may choose to eventually
upgrade for some reason.  Every little bit helps.

Improving MPEG-2 compression makes so much sense that one has to wonder how anyone would fail to get it.
 
In the US, the reason is obvious. In Europe, where SD and HD have to be simulcast, and where SD must continue to be broadcast using MPEG-2, it makes even more sense. So how Craig misses this is beyond comprehension.
 
The plain fact is, MPEG-2 compression is still improving, and that can only be good news. And this has absolutely nothing to do with whether or not H.264 or other newer codecs are used, where it makes sense to use them.
