Whether watching your favorite sporting event, music concert or movie on your HDTV, you’ll enjoy an amazing viewing experience. But, just because you buy an HDTV, doesn’t mean you are watching HD. For a true HD experience, you’ll need an HDTV, an HDTV source, HDTV channels or other HD content.
High Definition (HD) is a technological leap forward from standard definition with up to six times the picture resolution, so what you see is sharper and more realistic. HDTVs are capable of showing HD content and offer consumers a variety of choices in design, performance and technologies such as LCD, plasma and rear projection.
HD sources come in one of three different resolutions: 1080p, 1080i and 720p. 1080p is an HDTV standard that specifies a progressive scan resolution of 1,920 x 1,080 pixels. It is the standard resolution offered by Blu-ray Disc movies and the highest resolution widely available on HDTVs.
As of June 2009, broadcasters changed over from analog TV signals to digital broadcast, which means that every television must be equipped to receive digital signals in order to continue viewing.
