While the term High Definition is thrown around relatively frequently in today’s world, and its basic concept is understood by many, the specifics of the difference between the terms high definition and standard definition might be less clear.
At its truest designation, high definition is simply a larger number of pixels, or the tiny areas of light on a display screen, making up the image you see on the television. Imagine you’re drawing an image using only dots. The smaller the pen, the more dots you could place, and the clearer the image would look to an observer.
A standard definition television signal is made up of 213,840 pixels while high definition television signal at its lowest resolution (720p) is made up of 921,600 pixels. This larger number of pixels allows for the image to be increased in size without losing as much quality. To take this concept to an extreme, the signal that feeds the world’s largest high-definition display, the video board at the Dallas Cowboys’ AT&T Stadium, is the same signal resolution produced by most high definition Blu-ray disc playback devices available to consumers.
High definition also brings a multitude of other features thanks in part to the information transmission rates that High Definition TV (HDTV) signals allow compared to its predecessor. Audio is much clearer in high definition because the audio is now uncompressed because a larger amount of audio data can fit in HDTV cables. HDTV will also allow viewers access to more channels that are HD exclusive and the full Comcast On Demand library of shows.
