Case 3: Automatic Audio and
Video Switching via HDMI
If your A/V receiver has an HDMI output, it may be
convenient to route video signals from multiple devices
over a single cable to the TV. Use this procedure to set
up NetCommand control of the A/V receiver’s audio
and video switching over a single HDMI cable. The
connected source devices can be analog, digital, or a
mixture or the two. When this setup is complete, you
can use the TV’s
Activity menu to select a video device
connected to the A/V receiver.

More About Using an HDMI Connection
Audio from devices connected directly to the TV can •
be heard from the TV speakers only. To send audio
to the A/V receiver from such devices, use one of the
optional audio connections shown in the diagram on
this page. For example, use an optional audio con-
nection if you wish to use the A/V receiver speakers to
hear audio from:
The -
ANT
input
A game or camcorder -
To use NetCommand to supplement HDMI control of
•
a CEC-enabled A/V receiver, the recommended setup
sequence is:
Connect the HDMI cable.
1.

3.
desired.
Perform NetCommand setup.
4.
If you connect to HDMI after performing NetCommand
setup for the A/V receiver, the NetCommand setup will
be lost.
In some cases, audio from a device connected to the •
A/V receiver may not be passed over the HDMI cable
to the TV speakers. In these cases you must use the
A/V receiver speakers to hear audio.
Multiple video inputs through a single HDMI cable. You can
connect multiple video devices to an A/V receiver that has
an HDMI output. The optional audio connection allows you
to hear, through the A/V receiver, devices connected to the
TV only, e.g., an antenna on the
ANT input.

To complete these steps you will need:
The remote controls for both the TV and the A/V •
receiver.
An IR emitter cable (included)
•
An HDMI-to-HDMI cable to connect the A/V •
receiver to the TV and cables necessary to
connect devices to the A/V receiver.
