[opendtv] Re: New Thread: What becomes of Legacy Analog Equipment

Neither one of those listings use any standard, evolving or otherwise, to
denote HDTV.  TitanTV uses TV-Guide Gemstar data, where Tribune Media
Services (a more commonly used listing service) has a field in their data
structure to signal HDTV.  HDTV is a marketing term, not a technical one.  I
don't know where Yahoo gets their data, but there is no reason to expect
that a network program (indicated in the above listings as HDTV) would be
broadcast in HDTV by a station with an encoder that is not capable of
transmitting HDTV.

Is 720p (HDTV) any different than 1080i (HDTV)?  How about 1080p (HDTV)?
These aren't distinctions without a difference, but all are HDTV.

This stuff is only simple if you don't know the real-world considerations or
can ignore them.

It's obviously a judgment call though I personally think only the main 
shows count and any form of up conversions do not.  A show that is 
mostly HD but some upconverted material?  Who knows?

Sadly as many HD channels become more bit starved for multicasting it 
becomes harder to be sure about the up converts and on some channels 
maybe you couldn't even tell the difference.

Either way, an 'HD' listing attribute is something that is already being 
done and now shown in guides like TitanTV or Yahoo TV Listings so I 
guess there is already some sort of evolving standard for it.
