Installation 3-3
Video Connection Options
Use the following guidelines to determine the best video connection for the subscriber home
entertainment system. To determine the available video inputs on the TV, check the manual
supplied with the TV or the TV itself.
The DCT6400 offers the following video outputs:
Component
(Y Pb Pr)
HDTV and
SDTV
The Y Pb Pr outputs provide component video, the most widely supported HD video
connection.
HDMI
or
IEEE 1394
HDTV and
SDTV
HDMI and IEEE 1394 offer higher quality HD video than component video. If the TV
has an HDMI or a DVI input, use the
HDMI
output instead of the IEEE 1394 output.
HDMI and IEEE 1394 are video
and
audio connections. If you use HDMI or
IEEE 1394, no separate audio connection to the TV is required.
HDMI is compatible with DVI.
If the TV has a DVI input, you can use an HDMI-to-
DVI converter cable to connect to the DCT6400
HDMI
connector.
If you use IEEE
1394, on-screen graphics do not display.
S-Video
SDTV
only
If your TV has an S-Video input, use S-Video. S-Video is the highest quality
standard-definition video output on the DCT6400.
Video
(composite)
SDTV
only
If your TV does not have an S-Video input, use the composite video (
VIDEO
) output.
RF
SDTV
only
If your TV only
has a coaxial RF input, connect it to the DCT6400
RF
OUT
connector.
Audio Connection Options
Connect the stereo audio cable to the
AUDIO R
and
L
connectors on the DCT6400 and the audio
left and right connectors on the TV. If the equipment supports it, use the
OPTICAL SPDIF
or
coaxial digital
SPDIF
output instead of the
AUDIO R
and
L
outputs. In most cases, these outputs
offer better audio quality, including support for 5.1 Surround Sound.
When connecting to a home theater receiver, depending on its inputs, you can use the following
DCT6400 audio outputs:
OPTICAL SPDIF
or
coaxial
SPDIF
If the receiver supports it, use the
OPTICAL SPDIF
or coaxial
SPDIF
audio output to deliver
Dolby AC-3 audio to a Dolby Digital home theater receiver.
Baseband
AUDIO
R
and
L
If the audio receiver does not support Dolby Digital, use the baseband
AUDIO
R
and L
outputs to connect to the audio receiver.
The cabling diagrams show sample audio/video (A/V) connections to an audio receiver, where
the receiver functions as an A/V router. When connecting to an audio receiver, reference its
installation instructions for directions on connecting to baseband and S/PDIF ports.
The VCR and TV receive their A/V signals from the currently selected input device on the audio
receiver. This is important when the subscriber has another A/V device such as a DVD player, a
secondary VCR, a CD player, or other electronic component. We recommend connecting the TV to
the monitor output so on-screen menus for the receiver can be displayed. (In many cases the
receivers themselves have interactive on-screen menus).
