What is digital television?
Digital is a new format for TV broadcasting which has clearer images and better sound. A digital TV is one that can receive and display the new format. The best way to describe the picture quality difference between analog (older format televisions) and digital is that of VCR compared to DVD.
DTV also can offer multiple programming choices called multicasting. Digital technology allows each digital broadcast station to split its bit stream into 2, 3, 4 or more individual channels of programming and/or data services. (For example, on channel 7, you could watch 7-1, 7-2, 7-3 or 7-4.)
There is also a public safety aspect to the digital switchover. The conversion will free up parts of the broadcast spectrum, which can then be used by police and fire departments, emergency rescue and advanced wireless services.
