We have to say for DTH as the welcome of satellite programmes with a personal dish in an individual home. DTH stands for Direct-To-Home television. (DIRECT-TO-HOME) Satellite transmissions goal straight at separately households, to be received with a little dish. DTH does away with the need for the general cable operator and puts the broadcaster straightly in touch with the customer. Only cable operators can get satellite programmes and then they allocate them to separately homes. After the banned of the existing three-year DTH broadcasting has been made legal from November 3, 2000 in India.
The government has agreed the service, reversing the 1997 prohibition of instituting measures for regulation of content and prevent monopoly. On the whole DTH (direct-to-home) is a delivery platform for multi channel TV programmes on Ku (high frequency of 11.7 to 14.55 Gigahertz) band by using a satellite structure that will be transmits directly to subscriber premises. For multiple connections in the same group, one can use the same connection. However, every television set will need to have an separate 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.
A set-top box is a necessary for DTH. Earlier, when CAS made set-top box mandatory for households, the costs between DTH and cable would not have been too wide. But CAS on the backburner now -- which means no set-top box (a must for DTH), the price gap between DTH and cable will be wide. The users will not have to pay large amount to view channels of their interest. A normal investment of around Rs25,000 will link them to the multi-channel platform. This will include a pizza-sized 30 to 48 cm (12 to 18 inch) dish antenna for Rs.10,000 along with the TV set-top box, a digital decoder, for Rs. I5,000. Users will be provided with 'channel cards' which will act as pre-paid debit cards.
