Direct-to-Home (DTH) satellite television is becoming a buzzword in the satellite broadcast industry due to the fact that DTH offers immense opportunities to both broadcasters and viewers. Thanks to the rapid development of digital technology, DTH broadcast operators worldwide have been able to introduce a large number of new interactive applications in the television market besides a large number of entertainment programmes over a single delivery platform. In addition, since digital technology permits a highly efficient exploitation of the frequency spectrum, the number of TV channels that can be broadcast using digital technology is significantly higher than with analogue technology. The increased number of television channels allows the operator to satisfy the demand of a number of niche markets with dedicated transmissions.
In general, DTH service is the one in which a large number of channels are digitally compressed, encrypted and beamed from very high power satellites. The programmes can be directly received at homes. This mode of reception facilitates the use of small receive dish antennas of 45 to 60 cm diameter installed at convenient location in individual buildings without needing elaborate foundation /space etc. Also, DTH transmission eliminates local cable operator completely, since an individual user is directly connected to the service providers. However, a digital receiver is needed to receive the multiplexed signals and view them on a TV. DTH, in sharp contrast to Cable TV, lends itself to easy monitoring and control.
Transmission in Ku band is most appropriate and widely used for the purpose. As mentioned above, all the encoded transmission signals are digital - thus providing higher resolution picture quality and better audio than traditional analog signals. All the advantages of the digital transmission, as applicable to the terrestrial transmission are relevant in the satellite transmission also.
Tata-Sky offers 58-channels to consumers at an introductory offer of Rs 200 per month. You will have to pay Rs 3,999 for hardware (set-top box and installation), and a monthly charge of Rs 200.Zee group's Dish TV offers its hardware and installation at Rs 3,000 (excluding taxes) and three months' free subscription. This Dish TV package of 75 channels costs Rs 180 per month.DTH providers justify the prices as it offers high quality transmission which makes TV viewing a pleasant experience. Dish TV also offers other packages. The second DTH operator is government-owned DD-Direct Plus. This comes at a one-time cost of Rs 2,000-2,500.
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.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.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.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. DTH will not be able to be an alternative to cable if the initial investment is more than that for cable. DTH requires initial investment for both a dish antenna and a TV-top box.

Watching television will no longer be the same again. Bad transmission quality, blackouts, disconnection of channels, high cable bills -- all these could soon be history.
