High Definition Video
High Definition Video
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?
