high definition television
High definition television (HDTV) provides a much higher-quality television picture and audio than a standard television. High definition programming also differs from standard television programming in that it is delivered using a digital signal as opposed to an analog signal and has an aspect ratio of 16:9 vs. 4:3 for standard television. The wider aspect ratio is what gives high definition television its widescreen look and feel.
