The HDMI Ethernet Channel allows internet-enabled HDMI devices to share an internet connection via the HDMI

link, with no need for a separate Ethernet cable. It also provides the connection platform that will allow HDMI-

enabled components to share content between devices with speeds up to 100 Mbps [2].

The CEC bus is a one-wire “party line” that connects up to 10 A/V devices through standard HDMI cabling [4]. CEC

will automatically power on the appropriate products, route the DVD/Blu-ray’s audio output through the A/V re-

ceiver to the attached speakers, and route the player’s motion picture to the digital TV [4]. CEC enables automatic

equipment discovery and simple “one touch” operation in HDMI interfaced systems. Most installers and designers

prefer to turn oﬀ this functionality as it is usually not cross-brand compatible.
