Yep, it sure is. Richard is right.
Sadly, most broadcast systems use HDSDI as their primary interface.
Honestly, there's no problem until there is a need to have color continuity between a Playback deck and a media server.
Believe me, there's nothing worse than having to match footage and having a video engineer arguing wrong points. Then you get the content creators who complain because their creations look different from one medium to another when they themselves don't even understand Or apply Color Space.
However, theses are all issues which come into play when forced to convert to HDSDI.
But then again, neither can most codecs. It's a loosing battle.
It's all propaganda fed to media server people by broadcast engineers to justify the need to keep using interlaced.
THEIR ALL OUT TO GET US!!!! RUN!
The biggest Albatross of all is a $150k HD video projector that has a fiber input and the video company demands to use HDSDI.
