High Definition Multimedia Interface (HDMI)

The first industry-supported, uncompressed, all-digital audio/video interface. HDMI provides an interface between any audio/video source, such as a set-top box (HDTV Receiver), DVD player, and A/V receiver and an audio and/or video monitor, such as a digital television (DTV).

The new HDMI digital interconnect provides:

  • Superior, uncompressed digital video and audio quality.
  • Simple, user-friendly connector that replaces the maze of cabling behind the entertainment center.
  • Integrated remote control.
  • A popular interface enabling the transmission of high-definition content. HDMI opens the floodgate of digital content from major motion picture producers.

The advantages of HDMI over existing analog interfaces such as composite, S-Video and component video are.

  • Quality HDMI transfers uncompressed digital audio and video for the highest, crispest image quality.
  • All Digital HDMI ensures an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-to-analog conversions.
  • Low-cost HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-effective manner.
  • Audio HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound.
  • Ease-of-use HDMI combines video and multi-channel audio into a single cable, eliminating the cost, complexity, and confusion of multiple cables currently used in A/V systems.
  • Intelligence HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality.

HDMI is fully backward-compatible with DVI using the CEA-861 profile for DTVs. HDMI DTVs will display video received from existing DVI-equipped products, and DVI-equipped TVs will display video from HDMI sources. To see our selection of HDMI cables, please Click Here.

HDMI technology has been designed to use standard copper cable construction at long lengths. In order to allow cable manufacturers to improve their products through the use of new technologies, HDMI specifies the required performance of a cable but does not specify a maximum cable length. Cables are expected to be lengths of up to 15 meters.
