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 (not supplied), 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.
`
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.
