How is HDTV better than ordinary TV?
High definition is a cinema-style 16:9 widescreen digital TV format providing up to five times more picture information than ordinary, standard-definition TV – a resolution of up to 1920×1080 pixels compared to 720×576. The result is breathtaking detail, and vivid and lifelike colours. Sound is improved with high-quality 5.1 Dolby Digital surround sound and multichannel audio for different languages.
