It would not be hard for the device that outputs protected content (e.g. a
BR-DVD player) to simply refuse to output the program over the RF
connection.
But, given that most content played will be such protected content (at
least
Sony thinks it would be), where is the value to have such an output in
BluRay
if it will hardly ever be used?
OTOH, a PVR designed to play programs received from OTA, that should not
be
a problem in terms of DRM. Neither should such a modulator for a computer
as a plug-in card or USB/Firewire attached device.
A device that takes a component signal, however, would have to have
compression
included. And that makes it an expensive device. I've been looking for a
computer card that can take in component video, compress it, and pass it
over
the bus to the software driver in a compressed format like MPEG4, MPEG4-IO
*,
MJPEG, H.264, ATSC trans****t, etc. Ideally I'd like one that can do it
with
4:4:4 sampling, too.
[*] MPEG4-IO = MPEG4 with I-frames only (no B/P-frames)
