The Digital Advantage
Digital TV (DTV) represented a great leap in technology from its predecessor, with a vastly superior picture that was free of the static, ghosts, and radio interference that plagued analog TV. Digital TV also means more viewing choices, as digital broadcasting allowed stations to stream more than one program over a single channel. Today, DTV is the industry standard.
DTV made it possible for broadcasters to transmit high definition television (HDTV), the highest resolution digital TV format. HDTV brings images to life and puts viewers in the middle of the action like never before with these additional benefits:
Unlike analog’s square picture, HDTV programming offers a widescreen (16:9) format for a more theater-like experience. When viewed on a widescreen set, HD programming fills the screen without black bars (letterboxing) or a stretched picture.
HDTV offers resolutions up to five times that of analog TV, with anywhere from 720 to 1080 lines of either progressively scanned (p) or interlaced (i), as well as remarkable improvements in brightness and color depth. The incredibly detailed, life-like pictures make viewers feel like they’re part of the action.
Spectacular surround sound
Many HDTV programs are presented in Dolby® Digital surround sound. Sporting events, sitcoms, dramas, and feature movies are dramatically better in surround, which requires a surround audio system with center, front and rear channel speakers as well as a subwoofer.
