High definition television

HDTV (High Definition Television) has a resolution of 1920x1080 (in Europe) or 1280x720 (in the USA). But in the United States, progressive imaging is used, and in Europe, interlacing.
Thus, HDTV image clarity (the number of dots that make up the image) is almost 5 times greater than conventional TV. Those who see high-definition television are amazed at the quality of the image.
In all terrestrial television formats (except Western European PAL Plus), the aspect ratio of the picture is 4 to 3. And in high-definition television, the aspect ratio is 16 to 9. Therefore, a normal picture on an HDTV TV will either be stretched to full screen with aspect ratio distortion, or processed by a special algorithm to minimize this distortion, or the TV will display blank black bars around the edges.
Digital TV subscribers can independently choose how to display a standard 4:3 picture on an HD TV, i.ะต. can either crop the image at the top and bottom, or show the entire image but with empty bars on the left and right.
