Have been attempting to choose a Large screen monitor for use as t.v.
monitor, and I just spotted :-

"High-Bandwidth Digital Content Protection (HDCP) is a copyright protection
system that is incorporated into the DVI connector. It helps stop
unauthorized duplication of copyrighted content. HDCP allows you to play
protected content media such as movies and concerts. It checks the signal to
prevent piracy, allowing only legal copies of content to display.

Until just spotting this, I had always thought that a monitor with HDCP
comliant DVI port was desirable or required, to be able to, for example, to
play DVD's ...( though, have never had any trouble playing anything in PC
dvd drive !
....or would it be simpler to pay a bit more and get a monitor with a HDMI
socket on it.
I don't have HDMI port on the back of old AGP 7800GS graphics card but, it
does have a DVI-I (and VGA port) on it, ...and SVHS but, don't intend to
use that, and I do have a DVI-I to HDMI adapter, that came with the 7800 GS
card.

.....any tips appreciated.

regards, Richard

You don't need anything special to play DVD. Have a Pentium2 300MHZ, with a
4Mb on board video card that will do that. You'll need HDCP to get the most
out of Blue Ray. HDMI is the same as DVI-D except it
also has digital audio. both can have, or not, HDCP. DVI-I has both DVI-D
and DVI-A. You can check out all these terms on Wikipedia in much greater
detail than anyone is likely to post here.

HDCP encrypts the data stream between the video card and the monitor. That
is to prevent someone from copying the data on the monitor cable. The overall
framework is described here.

http://en.wikipedia.org/wiki/PVP-OPM

There are plug-in cards, that can record HDMI signals. The Blackmagic Intensity
Pro for example. To avoid problems with the Content Police, this device is
hobbled in two ways. First, it doesn't understand HDCP. So if you plug an
HDMI cable with an HDCP-protected movie playing on it, all this card sees is
"noise". Second, this card cannot handle the larger resolution images - the
company that makes the main chip, makes some more capable versions of the chip,
but those chips are only for usage in fully protected implementations (not to be
used in a recording card of this type). So they can't be used by Blackmagic,
without them getting in trouble.

http://www.projectitalia.it/img/schede video/intensitypro.png

The main purpose of the Blackmagic card, is to accept the HDMI
output of a high end camera. The camera output would say the
content was not protected, because it is originally recorded material,
and not Hollywood content.

This is all silly of course, because anyone wishing to pirate Hollywood content,
is already doing it. The main side effect, is it being an inconvenience for
consumers.

HDCP is mainly for Blu-Ray disks and HD TV signals. Most "stand-
alone" video card made with chips from ATi or nVidia would normally
allow HDCP signals. You will need to use the standard video card
drivers.
