• HDMI (High Definition Multimedia Interface)
HDMI is an interface to enable the digital transmission of video and audio data with just a single connector.
Using HDMI, the DVD player 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 Bitstream data).
- The player 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.
• 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 DVD player) 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 player 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.
