There have been lots of questions over at AVS Forum
about Vista Media Center
and unencrypted QAM. I think those who
want unencrypted QAM (Clear QAM) might have more luck with Vista,
but only if using a PC with OCUR (CableCARD Reader).
CableLabs says that an OCUR must be able to function without
a CableCARD and make available “unscrambled digital high-definition”
content as defined in ANSI/SCTE 43.
If CableLabs says the OCUR must do it, then I assume this
means that Microsoft is obligated to have Media Center
scan for unencrypted QAM and map it in the EPG.
1080i29.97 and 1080i30 are included in SCTE 43. As is 720p at just about
every frame rate.
I don’t know about getting QAM working with other HDTV
tuners like the Fusion, Vbox, etc. but unencrypted QAM lovers might have more
luck in Vista and OCUR.
Update: Stephen correctly pointed out in the comments that Microsoft doesn’t have an obligation to map unencrypted QAM channels to the EPG, rather they should have an obligation to allow tuning of unencrypted QAM with the use of an OCUR.
