HDTV or high definition television normally refers

to any video system of higher resolution than the

standard definition. The original HD specifications

date back to the early 1980s, when Japan first

experimented with a 1025 line television standard.

Japan presented their parameters at an international

meeting of television engineers in Algiers in 1981

and Japan’s NHK presented their analog HDTV system

at a Swiss conference in 1983. Except for these

early formats, HDTV is digital broadcast and

therefore it’s introduction will sometimes conincide

with the introduction of DTV, or digital television.

The signals for high definition require a high

definition television or a computer monitor in order

to be watched or viewed. High definition video

will normally have an aspect ratio of 16:9. The

aspect ratio of the regular widescreen film that is

shot today is normally 1:85:1 or 2:40:1. The

standard type of television has a 4:3 aspect ratio.

High definition television resolution is 1080 or

720 lines. With the contrast, regular digital

television is 480 lines or 576 lines. The current

quality with DVD is not high definition, although

high definition systems such as HD-DVD and Blu-Ray

are both expected to be and ship later on in 2006.

The most noted feature with high definition video

is the fact that it’s so life like. There is HDTV,

and HD video cameras. High definition is very

popular these days, with television being at the

top of the list.

High definition video cameras are getting just as

popular, as they offer you the chance to capture

memories like never before. HD offers you video

like never before, making you wonder if things are

this good now – just what will video in the future

actually be like,
