DTH TV HAS CHANGED TV VIEWING IN URBAN INDIA. IT PROVIDES QUALITY RECEPTION AND SERVICES SUCH AS INTERACTIVE MULTIMEDIA.
Direct-to-home brings quality television programming right into your home via a satellite dish. How Things Works explains how the whole process takes place.
In direct-to-home (DTH) telecast, TV channels/programmes are directly distributed via satellite to the subscribers’ homes without the content going through a cable operator. The signals are transmitted in Ku band (10.7 GHz to 18 GHz) and are received by the subscribers through a small dish antenna and a set-top box. The DTH system can also provide many value-added services such as the Internet, e-mail, data casting, e-commerce, and interactive multimedia.
Satellite TV solves the problems of range and distortion by transmitting broadcast signals from satellites orbiting the Earth. Since satellites are high in the sky, the larger line of sight can accommodate a lot more customers. DTH transmits and receives radio signals using specialised antennas called satellite dishes. The first movers in India were Dish TV and Tata Sky, followed then by Sun, Big TV, Airtel Digital, Videocon, etc.
Programming sources are simply the channels that provide programming for broadcast. The provider (the DTH platform) doesn’t create original programming itself; it pays other companies (HBO, for example, or ESPN, Aaj Tak, Headlines Today etc.) for the right to broadcast their content via satellite. In this way, the provider is a kind of broker between the viewer and the actual programming sources. 1 Programming source provides content for broadcast. Satellite TV providers get programming from two major sources: international channels and various local channels. Turnaround channels usually have a distribution centre that beams their programming to a geostationary satellite.
