HDMI-CEC is a device control protocol that runs over HDMI cables.
It allows rudimentary control over HDMI-CEC aware devices - these devices oftern have vendor-specific names for the protocol, such as AnyNet+ for Samsung devices.
There are new devices becoming coming available that support a USB-HDMI bridge - one such device is from RainShadowTech (www.rainshadowtech.com).
These instructions have been developed using the RainshadowTech device - differences will exist.
