What is digital TV and how does it work?
Conventional analog television transmits a continuous signal which has a direct relationship to the content that it carries. That is, the content is transmitted in its entirety from transmission to reception. With digital television, the content is highly compressed into a binary code of ones and zeros, which are then transmitted to your home where your television or other digital reception equipment decodes them into the sounds and pictures that you watch as television. Digital transmitters and receivers are far more complex than those used in analog systems and allow for the reception of additional data and offer significantly more in the way of content and features than analog technology. For example, the space that was previously used to carry the single analog ABC television signal now carries ABCHD, ABC1, ABC2, ABC3, ABC DiG Radio and ABC DiG Jazz. ABC DiG Radio and ABC DiG Jazz are audio streams that you can receive on your television receiver.
