What's the difference between DVI and HPCP?

Archived from groups: alt.tv.tech.hdtv (More info?)

DVI = Video
HDMI = Video and Audio

The video characteristics are the same in both.

Note regarding cable card - without a set-top box you want have access to
two-way features, such as ordering PPV (can usually be done via phone) but
more importantly you won't have program guide info.

I think you meant HDCP not "HPCP"... DVI is a type of connector that can
carry a digital video signal (DVI = digital video interface), whereas HDCP
is an encryption protocol used to prevent/circumvent copying of digital
signals carried through the DVI connector. Some of the older sets equipped
with DVI are actually not HDCP compatible, meaning they won't accept a
digital signal through DVI if it's encrypted with HDCP. This can cause
significant problems as most of the cable/satellite boxes nowadays output a
HDCP-encrypted signal.

Just in case you were wondering about HDMI as well, it is the same as DVI (a
type of physical connector / electrical interface), with the difference that
it can also carry a digital audio signal. DVI only carries video. The newer
TV sets ship with HDMI or with both.
