Why is HDTV better than “regular” SDTV?
A. HDTV brings viewers five times the picture resolution and clarity of SDTV, making viewers feel like they are right in the middle of the action on their screens. HDTV uses binary code, the same system of ones and zeroes that run on computers and digitally recorded compact discs. With a 16:9 aspect ratio, HDTV has a wider, rectangular screen, compared to today’s square 4:3 aspect ratio of analog television. The wider image is more lifelike and realistic.
