Why does Samsung use HDMI?

Analog TVs require an analog video/audio signal.
However, when playing a DVD, the data
transmitted to a TV is digital. Therefore either 
a digital-to-analog converter (in the HDD & DVD
RECORDER) or an analog-to-digital converter 
(in the TV) is required. During this conversion, 
the picture quality is degraded due to noise and
signal loss. HDMI technology is superior because
it requires no D/A conversion and is a pure digital
signal from the HDD & DVD RECORDER to your
TV.

What is the HDCP?

HDCP (High-bandwidth Digital Content
Protection) is a system for protecting DVD content
outputted via HDMI from being copied.
It provides a secure digital link between a video
source (PC, DVD. etc) and a display device 
(TV, projector. etc). Content is encrypted at the
source device to prevent unauthorized copies
from being made.

HDMI (High Definition Multimedia
Interface)  
HDMI is an interface to enable the digital
transmission of video and audio data with
just a single connector. Since HDMI is
based on DVI, it is completely compatible
with DVI. The only difference between
HDMI and DVI is that HDMI supports
multi-channel audio.
Using HDMI, the HDD & DVD
RECORDER transmits a digital video and
audio signal and displays a vivid picture
on a TV having an HDMI input jack.

HDMI connection description

HDMI connector - Both uncompressed
video data and digital audio data 
(LPCM or Bit Stream data).

-  Though the HDD & DVD RECORDER

uses a HDMI cable, the HDD & DVD
RECORDER outputs only a pure digital
signal to the TV.

-  If TV does not support HDCP 

(High -bandwidth Digital Content
Protection), snow noise appears on the
screen.
