HDMI is the first & only industry supported, uncompressed, all-digitalaudio/video interface.

HDMI provides an interface between any A/V source, such as a set-top box,DVD player, or A/V receiver and an audio or video monitor, such as a digitaltelevision (DTV), over a single cable.

HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable.

Transmits all HDTV standards and supports 8-channel, 192kHz,uncompressed digital audio, all currently-available compressed formats &

lossless digital audio formats with bandwidth to spare to accommodatefuture enhancements and requirements

Specifications

The HDMI specification defines the protocols, signals, electricalinterfaces and mechanical requirements of the standard.

The maximum pixel clock rate for HDMI 1.0 was 165 MHz,which was sufficient for supporting (1,9201,200) at 60 Hz.

HDMI 1.3 increased that to 340 MHz, which allows for higherresolution (2,5601,600) across a single digital link.

An HDMI connection can either be single-link (type A/C) ordual-link (type B)

For single-link connection video pixel rate of 25 MHz to

340 MHz For dual link connection 25 MHz to 680 MHz

Video formats with rates below 25 MHz

Connectors

Type A-Nineteen pins, with bandwidth to support all HDTV modes.Type A is electrically compatible with single-link DVI-D.

The plug (male) connector outside dimensions are 13.9 mm 4.45 mm and the receptacle (female) connector inside dimensions are

14 mm 4.55 mm. Type B-This connector has 29 pins and can carry double the video

bandwidth of type A. Type B is electrically compatible ,but has not yetbeen used in any products.

Type C-A Mini connector defined in the HDMI 1.3 specification, it is

intended for portable devices . It is smaller than the type A plugconnector but has the same 19-pin configuration.

Type D-A Micro connector keeps the standard 19 pins of types A andC. The type D connector is 2.8 mm 6.4 mm.

Type E-Automotive Connection System

Currently the answer is to have an equalizer.

Cables of long lengths have equalizers in them, easy solution,cable life is shortened.

Equalizers can be fixed, adjustable and adaptive.

Cat5 extenders, allow for meters of added distance using Cat5cable, but requires a transmitter and receiver.

Going the Distance

Manufacturing, non-approved HDMI cables can produce poor results

Poor installation, long cable runs, improper active devices, lack ofknowledge

Twisted cables, interconnects, connectors, and electronic componentscan create a maze of signal loss
