What does HDMI do?

High-Definition Multimedia Interface (HDMI) cables and HDMI extenders offer numerous audio-visual benefits, resulting in a more efficient, higher quality experience for users – they effectively streamline the entire home entertainment experience. Providing the best in both uncompressed audio and video, HDMI cables and HDMI extenders process and transmit AV signals over one thin cable with a single user-friendly connector. HDMI cables and extenders are also backwards compatible with Digital Visual Interface (DVI), needing only a passive cable or adapter to connect signals between the two. One of the most lauded features of HDMI cables and extenders is their support of up to 8 different digital audio channels – all full-resolution, all on the one cable. HDMI cables and extenders can also transmit basic control codes between HDMI-capable devices (CEC), meaning total entertainment system integration is now easier than ever.

Unlike one-track analog cables of the past, HDMI cables and extenders can process a variety of signals and inputs at the same time. Instead of having to configure S-video, component or composite video, and RF, in addition to coax-based or optical digital audio signals, everything can now be processed through a single HDMI connection. When it comes to using an SACD or DVD Audio-capable player, one HDMI cable can do the work of up to ten other cables and connections simultaneously – instead of 6 separate cables used to process 5.1 multichannel analog audio; 3 other cables used to digitise analog component video; and 1 more needed for coax or optical digital audio output.

The latest versions of HDMI cables and HDMI extenders now more than double the signalling bandwidth available – from 4.95 gigabits per second to a whopping 10.2 gigabits per second. This significant increase offers unparalleled screen resolutions, superior refresh rates, and life-like depths of colour for your viewing experience. Also integrated is the new xvYCC colour spectrum that fully supports both Dolby's DTS-HD and TrueHD Master Audio standards. HDMI cables and extenders also provide a mini-connector – ideal for digital still and video cameras – with the power to accurately and automatically adjust audio playback, ensuring lip synchronisation alongside the captured video image.
