What is DTH?
DTH stands for Direct-To-Home television. DTH is defined as the reception of satellite programmes with a personal dish in an individual home DTH does away with the need for the local cable operator and puts the broadcaster directly in touch with the consumer. Only cable operators can receive satellite programmes and they then distribute them to individual homes.
How does DTH work?A DTH network consists of a broadcasting centre, satellites, encoders, multiplexers, modulators and DTH receivers.
A DTH service provider has to lease Ku-band transponders from the satellite. The encoder converts the audio, video and data signals into the digital format and the multiplexer mixes these signals. At the user end, there will be a small dish antenna and set-top boxes to decode and view numerous channels. On the user's end, receiving dishes can be as small as 45 cm in diametre. DTH is an encrypted transmission that travels to the consumer directly through a satellite. DTH transmission is received directly by the consumer at his end through the small dish antenna. A set-top box, unlike the regular cable connection, decodes the encrypted transmission.
How does DTH really differ from cable TV?
The way DTH reaches a consumer's home is different from the way cable TV does. In DTH, TV channels would be transmitted from the satellite to a small dish antenna mounted on the window or rooftop of the subscriber's home. So the broadcaster directly connects to the user. The middlemen like local cable operators are not there in the picture. DTH can also reach the remotest of areas since it does away with the intermediate step of a cable operator and the wires (cables) that come from the cable operator to your house. As we explained above, in DTH signals directly come from the satellite to your DTH dish.Also, with DTH, a user can scan nearly 700 channels!
Does one need to put two dish antennae and pay double subscription per month if one has two TVs?
For multiple connections in the same premises, one can use the same connection. However, every television set will need to have an individual STB. Also, DTH is a national service and the STBs enable a viewer to change service providers without changing the STB, even if one moves from one city to another.
Can a CAS set-top box be used for DTH?No, these are different set-top boxes.
Is DTH superior to cable TV?
Yes. DTH offers better quality picture than cable TV. This is because cable TV in India is analog. Despite digital transmission and reception, the cable transmission is still analog. DTH offers stereophonic sound effects. It can also reach remote areas where terrestrial transmission and cable TV have failed to penetrate. Apart from enhanced picture quality, DTH has also allows for interactive TV services such as movie-on-demand, Internet access, video conferencing and e-mail. But the thing that DTH has going for it is that the powerful broadcasting companies like Star, Zee, etc are pushing for it.
So why are broadcasters pushing for DTH?
- In DTH, the payments will be made directly by the subscriber to the satellite company offering the service.
- A big problem that broadcasters face in India is the issue of under-reporting of subscribers by cable operators.
Consider the cable operators pyramid. Right at the top is the broadcaster. Next comes the Multi Service Cable Operator (MSOs) like Siticable, InCable, etc. Below them are the Access Cable Operators (ACOs) or your local cable guy who actually lays the wires to your house.
