What is HDMI?
HDMI (High-Definition Multimedia Interface) is 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, DVD player, and A/V receiver and an audio and/or video monitor, such as a digital television (DTV).
HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable.
It transmits all ATSC HDTV standards and supports 8-channel digital audio, with bandwidth to spare to accommodate future enhancements and requirements.
How do consumers benefit from HDMI?
The new HDMI digital interconnect provides:
1) Superior, uncompressed digital video and audio quality
2) Simple, user-friendly connector that replaces the maze of cabling behind the entertainment center
3) Integrated remote control
4) A popular interface enabling the transmission of high-definition content. HDMI opens the floodgate of digital content from major motion picture producers
What is the life expectancy of HDMI?
HDTV uses less than 1/2 of HDMI's available 5 Gbps bandwidth.
With capacity to spare, HDMI can incorporate new technology advancements and capabilities long into the foreseeable future.
Does HDMI provide a secure interface?
HDMI, when used in combination with HDCP, provides a secure audio/video interface that meets the security requirements of content providers and systems operators.
What types of video does HDMI support?
HDMI has the capacity to support existing high-definition video formats (720p, 1080i, and even 1080p).
It also has the flexibility to support enhanced definition formats such as 480p, as well as standard definition formats such as NTSC or PAL.
Does HDMI accommodate long cable lengths?
Yes. 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.
Cable manufacturers are expected to sell reasonably priced copper cables at lengths of up to 15 meters.
As semiconductor technology improves, even longer stretches can be reached with fiber optic cables, and with active cable technologies such as amplifiers or repeaters.
