What is High-Definition Television (HDTV)?

High-Definition Television (HDTV) is a TV display technology that provides a higher picture and sound quality than standard TV. HDTV resolution is 6 times sharper than Standard Definition (SD).  In addition, the color resolution for HDTV is more than twice that of the standard television system.  The HDTV 16/9 width to height ratio is also much wider than that of the standard television system's 4/3 ratio.  This gives the viewer a 1/3 wider screen, closely resembling the wide screen image seen in a movie theater.
