DVI to HDMI
Digital Visual Interface or DVI cable was designed to primarily to maximize visual quality of LCD digital displays and digital projectors.
The ( DVI ) Digital Visual Interface cables
use a digital protocol giving the desired
illumination to pixels and is transmitted as binary data. If the (LCD)
display
is used at normal resolution
it will read each of the numbers and apply the appropriate brightness
to the correct pixel. Each of the pixels in the output buffer of the
source
device corresponds directly to one pixel in the display device. An
analog signal, the appearance of the pixels can be affected by
its adjacent pixels. A (DVI) connector usually contains pins to pass
the DVI-native
digital video signals. Dual-link systems use additional
pins for the second set of data signals. A DVI connector includes pins
providing the same analog signals used in VGA connectors. This makes it possible for a VGA monitor to be connected with a simple plug adapter. This feature
was included in order to make DVI universal.
High-Definition Multimedia Interface or HDMI cable is a licensable audio/video connector interface for transmitting uncompressed, encrypted digital streams.
HDMI
High-Definition Multimedia Interface cables
are the new solution that will replace DVI. HDMI supports all TV or CPU
video format. This includes standard, high-definition video,
or multi-channel digital audio on one
cable.
It is independent of the various TV standards like (ATSC) and
(DVB) part of the MPEG
movie data streams. The data streams are sent to a decoder
and the output as
uncompressed video data. HDMI encodes this video data into (TMDS)
for digital transmission over HDMI. The new HDMI specs. have
expanded to include three types of connectors, each of these are
intended for very different markets.
