Your
receiver is also going to be outputting video data to your
TV in most cases. This means connecting the monitor video
output(s) of the receiver to the input(s) on the TV. With
that in mind, we'll take a look at the various ways that a
TV might be connected to a receiver.
There are three scenarios in this
diagram: HDTV, SDTV with video inputs, and SDTV with RF input
only. We'll start with the HDTV.
HDTV: Connection
(1) is a DVI or HDMI
digital video cable from the receiver to the TV. Make this
connection if you have a DVI or HDMI input, your receiver
offers switching for either format (since the two are interchangeable,
it doesn't matter if the receiver has DVI switching and the
TV has an HDMI input), and you have or plan to have more than
one DVI/HDMI source. Connection (2) is a
component video connection (three cables).
Make this connection – the only reason to skip this one is
if your receiver transcodes analog video to the digital output
(DVI or HDMI) and you have a DVI/HDMI input on the TV. The
diagram doesn't show connecting s-video or
composite analog video. You would only need
to make this connection if your receiver does not offer video
transcoding from composite/s-video to component and you have
composite or s-video sources.
SDTV: Connection
(3) is a component video
connection (three cables), which you should make if your SDTV
has a component input and your receiver offers component video
switching. Many SDTV's (especially older units) don't have
a component video input, in which case you will want to skip
this and move on to the next connections. Connection (4)
is an s-video cable. Make this connection
if your TV lacks a component input or if your receiver does
not offer transcoding from s-video to component. Some TV's
will not offer an s-video input, either, which takes us to
connection (5): a composite
video cable. This is the video connection of last resort.
Use it only if you don't have a better input or if your receiver
lacks any transcoding of composite inputs up to s-video or
component video.
SDTV with RF input:
This is going to be extremely rare in a home theater system
today – a monitor that lacks any analog video inputs. Connection
(6) is a composite cable
connected to an RF modulator, with a coaxial
cable run from there to the TV's antenna input.
