Copy Protection...
What is HDCP?
HDCP stands for High-Bandwidth Digital Content Protection, a copy protection
scheme to eliminate the possibility of intercepting digital data midstream
between the source to the display. The format designed by Intel and
licensed by Digital Content Protection, LLC using an authentication and key
exchange procedure before video and audio is presented. Products compatible
with the HDCP scheme such as DVD players, satellite and cable HDTV
set-top-boxes, as well as few entertainment PCs requires a secure connection
to a compliant display, the process often described as the handshake. Due
to the increase in manufacturers employing HDCP in their equipment, it is
highly recommended that any HDTV you purchase is compatible. Although most
video devices support high-definition video over component output, analog
connections are scheduled to phase out in the future or possibly forced to
limited resolutions output.
Why is it important to me?
Although manufacturers are still making most products with at least
component HD output, new generation of products like HD-DVD and Blu-Ray
devices will limit the analog output resolution (Analog defined as Component
or RGBHV). The highest resolutions these devices can output
(720p/1080i/1080p) will be available on via the digital (DVI or HDMI)
connections that employ HDCP encryption. Any new HDTV purchase should have
a digital HDCP compatible input.
It is important to note that HDCP is currently not a standard used in PC
monitors, and almost none of these displays have Component inputs. Although
PC monitors are HDTV capable, HDCP encryption limits this type of use. If
you use an HTPC and want to ensure dual use of your new flat panel display,
look for HDCP compatibility.
What its saying is that your Video card and Monitor must be HDCP compliant
.....one or both of yours is not
