Though DBS and DTH present the same services to the consumers, there are some differences in the technical specifications. WhileDBS is used for transmitting signals from satellites at a particular frequency band [the band differs in each country], DTH is used fortransmitting signals over a wide range of frequencies [normal frequencies including the KU and KA band]. The satellites used for thetransmission of the DTH signals are not part of any international planned frequency band. DBS has changed its plans over the past fewyears so as to include new countries and also modify their mode of transmission from analog to digital. But DTH is more famous for itsservices in both the analog and digital services which includes both audio and video signals. The dishes used for this service is also verysmall in size. When it comes to commercial use, DBS is known for its service providing a group of free channels that are allowed for itstargeted country.
DTH in India
India is one of the biggest DTH service providers in the world. The requirement is very high because of the high population and theincreased number of viewers. The low cost of DTH when compared to other local cable providers is also one main reason for thissubstantial growth.
The idea of DTH was first provided to India in 1996. But it was not approved then as there were concerns about national security. Butthe laws were changed by the year 2000 and thus DTH was allowed. According to the new rule, DTH providers are required to set upnew stations within 12 months of getting the license. The cost of the license is almost $2.15 million in India with a validity of 10 years forrenewal. The latest reports suggest that almost 25% of the total Indian population use this facility while others use local TV connections.
