Definition: The DTH technology enables a broadcasting company to directly beam the signal to your TV set through a receiver that is installed in the house. There is no need for a separate cable connection.

Description: In India, direct-to-home (DTH) Broadcasting Service refers to the distribution of multi channel TV programmes in Ku Band by using a satellite system by providing TV signals direct to subscribers' premises. For DTH connection the broadcasting company provides a set that comprises the dish and a receiving set. The company beams an encrypted signal that only the set installed in your household can receive and enable viewing.

DTH has many advantages like one can do away with the cable operator who will give you channels of his choice and there is no assurance of quality. The quality of signals in this case is expected to be superior since the signal is not split through a cable. By choosing just the signals that one needs, there is a possibility of reducing your monthly cable bill.

Among disadvantages, the biggest one is the capital cost that has to be borne initially. Since this involves setting up of a receiving apparatus at the subscribers end, the cost can be prohibitively high.
