With DTV broadcasting, the audio, video and data signals are transmitted as a series of 1s and 0s, just as in your computer. With digital you do not experience any degradation of signal quality during transmission. However, if you lose the signal, the picture will completely disappear. Broadcasting with digital is all or nothing. The best analog picture can never compare with a digital picture.
Digital signals produce clear and crisp TV pictures unlike any available from analog technology.
High-definition television will offer as many as 1,080 lines of resolution, compared with analog's 480. DTV will display a wider, more cinematic screen shape. The aspect ratio-of existing televisions are 4 x 3. The new digital standard will provide an aspect ratio of 16 x 9. OET and it's network of public television stations around the state will embrace this benefit of DTV for our viewers by broadcasting and producing enhanced digital television programs.
