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.

•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.

1.Connect the A/V receiver to the TV with an HDMI-to- HDMI cable. Do not connect the optional audio cable at this time.

2.If desired, enable HDMI Control of a CEC-enabled A/V receiver. See Appendix C, “HDMI Control of CEC Devices.”

3.Connect your audio/video devices to the A/V receiver. Note the name of the device connected to each A/V receiver input. This information will be needed later to set up NetCommand’s automatic input switching.
