HDMI is for Video and Sound. With 19 wires wrapped in a single cable, HDMI is able to carry a bandwidth of 5 Gbps (gigabits per second). This is more than twice the bandwidth needed to transmit multi-channel audio and video. HDMI handles both Video and Sound.

Pioneer Electronics is one of the culprits pushing HDMI technology, and their DV59-AVi was one of the first to market with HDMI jacks. HDMI has supported HDCP since the beginning, starting at HDCP 1.1 and reaching HDCP 2.2 with HDMI 2.0. HDCP can cause issues with longer cables, and ultimately it appears to annoy consumers more than the pirates. At present, known hacks / workarounds to strip HDCP 2.2 from video signals can be found. === Cable Size ====== Cable Advancements ===The new HDMI specification for High Performance HDMI includes an over 75% increase in the bandwidth requirement, from 10.2Gbps to 18Gbps. High Speed HDMI Cables are engineered to deliver a full 18Gbps data required by the new HDMI specification. Cables have also improved in physical flexibility. The original HDMI cables that hit the market were very stiff and difficult to work with. Quality manufactures are now producing HDMI cables that put less stress on the socket of video equipment.=== CEC ===CEC (Consumer Electronics Control) is the control protocol found in HDMI. If you've not heard of CEC, you may have heard of it in another form, Sony call it Bravialink, LG call it Simplink and Samsung call it Anynet+ . This allows HDMI devices to control each other and allows the user to operate multiple devices with one remote control handset or device interface. HDMI-CEC is a one-wire bidirectional serial bus that uses the industry-standard AV.link protocol to perform remote control functions. CEC is carried on pin 13 in the HDMI cable connector. Media center systems XBMC and [[MythTV]] already support HDMI-CEC. The specifications have been revised since the original HDMI and some manufacturers deviate from the specs. Complete compliance is not always available. CEC wiring is mandatory, although implementation of CEC in a product is optional.A common example of CEC use is a feature called "One Touch Play." By pressing the play button on a DVD player, a command is issued to a downstream A/V Receiver to automatically power on, switch to the active HDMI input, and similarly send the same power on and input switch commands to the HDTV.
