Output Connection
HDMI
Unlike a DVI connection, an HDMI connection is capable of carrying
digital video and audio signals to the TV or a home theater receiver
equipped with HDMI switching support.
The HDMI connection can deliver Dolby Digital Plus, Dolby Digital,
Linear PCM, and other digital audio formats to a compatible TV or home
theater receiver.
Digital audio optical
(S/PDIF)
If the TV or home theater receiver supports it, use the S/PDIF digital
audio optical output to deliver Dolby Digital and Linear PCM audio to a
Dolby Digital home theater receiver.
For an HDMI or IEEE-1394 video connection, no additional audio
connections to the TV are required.
Baseband Audio L and R
If the audio receiver does not support Dolby Digital, use the baseband
AUDIO L and R outputs to connect to the audio receiver.
If the customer equipment supports it, use the optical S/PDIF output instead of the
AUDIO L and R outputs. The S/PDIF output offers better audio quality, including support
for Dolby Digital 5.1 Surround Sound. The HDMI interface supports Dolby
®
Digital Plus
(7.1) audio.
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 digital
audio (S/PDIF) ports.
Note: 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, secondary VCR, CD player, or other electronic component. Motorola
recommends connecting the TV to the monitor output so on-screen menus for the
receiver can be displayed. (Receivers themselves often have interactive on-screen
menus.)
