The Advantages of Digital TV Over Analog
Television stations are all converting to digital transmission for a reason. The digital broadcast signal has numerous advantages over the analog signal that will aid television broadcasts in the present and help them prepare for the future. These advantages outweigh the inconveniences of converter boxes and new TV sets.
Digital TV signals are much more compact than analog signals. This means they take up less space within the bandwidth, leading to more room for more stations in one region.
Digital tuners remove any interference from the TV signals before converting them into the pictures and sounds, meaning there is no distortion like "static" or "snow" on the picture.
Digital TV permits wider "letterbox" style image screens, meaning watching programs on TV sets will be closer to watching movies on screens.
Digital TV allows for high-definition television, which means an even clearer, more realistic picture and higher quality sound.
Digital TVs will have an automatic user interface so even those watching basic broadcast can preview other channels without "channel surfing," much like what cable and satellite users have.
