INTRODUCTION : 

INTRODUCTION 3 DTH stands for DIRECT-TO-HOME television. DTH is defined as: The reception of satellite programmers 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 consumer .

HISTORY : 

HISTORY DTH services were first proposed in INDIA in 1996. But was not approved due to the concerns over national security. Finally, in 2000 DTH was allowed and it was Doordarshan which make it possible to provide its facilities to consumers from 1st April 2000. Broadcasters like STAR and ZEE are pushing hard for DTH services in INDIA. The operators were required to setup earth stations in INDIA within 12 month for getting license of broadcasting whose cost was $2.14 million and will be valid for 10 years. 4

HOW DOES DTH DIFFER FROM CABLE TV…? : 

HOW DOES DTH DIFFER FROM CABLE TV…? In DTH, TV channels would be transmitted from the satellite to a small dish antenna of the subscriber's home. The broadcaster directly connects to the user. The middlemen like local cable operators are not there in the picture. DTH followed cable TV in Urban while in Rural, it was riding on its own but the cable TV is limited in Urban areas. DTH will be definitely more expensive than cable as it exists today. 7

IS DTH SUPERIOR TO CABLE TV…? : 

IS DTH SUPERIOR TO CABLE TV…? DTH offers better quality picture than cable TV. DTH offers stereophonic sound effects. It can also reach remote areas where terrestrial transmission and cable TV have failed to penetrate. DTH has also allows for interactive TV services such as Internet access, video conferencing and e-mail. The thing that DTH has going for it is that the powerful broadcasting companies like Star, Zee, etc are pushing for it. 8
