The word ‘DTH’ is synonymous with transmission of digital video channel to home subscriber’s using a small dish antenna. The DTH utilizes a technology which enables a home to receive high speed internet broadband access data communication, voice over internet protocol (IP) telephony and much more using an open standard Digital Video Broadcasting (DVB) technology. The video channels are received with a suitable set top box. Capable of demodulating Motion Picture Engineering Group (MPEG-2) standard videos. It is for the return channel required for other services such as voice over internet protocol and broadband access data communications, that a return channel is also required for the home terminal. The return channel via the satellite is called RCS and is an open standard.
Hardware compatible with DVB-RCS technology are readily available in the market in both Ku-band and C-band. DVB-RCS is an international open standard for multimedia satellite network where the return data rates in access of 2 Mbps are possible using low cost user terminals. The forward ink is usually at 40 Mbps. Today, most satellite TV customers in developed television markets get their programming through a direct broadcast satellite (DBS) provider, such as DISH TV or DTH platform.

Dth and Challanges

...Chapter 1 (Introduction) INTRODUCTION:- 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! 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... From slums to high rises, interior villages to the swankiest locations, one consumer electronic appliance that you’ll see in Indian homes is the TV.

That is “Doordarshan” which was owned and operated by government of India. At the time of 90’s every home which had a TV set used to have its own antenna to capture the signals. The Cable Television Ordinance Law was passed in January 1995. This enabled cable operators to feed channels and later on private companies were allowed to air their own channels and this led to the explosive growth in number of TV channels and number of cable operators. The growth of TV channels & cable operators created a big industry and market opportunities. There were as many as 1, 00,000 cable operators across India until few years back. However the services provided by cable operators were poor. The strikes, increase in tariff plan, selective broadcast and poor services were major cause of dissatisfaction among the customers. This has created an opportunity for DTH. What is DTH? DTH stands for Direct-To-Home, it’s a system that allows you to have a personal dish antenna how cable operators do, except it’s much smaller in size, this antenna can be fixed on your terrace and receives transmissions directly from a satellite, hence it is called as a direct to home service.

Project Report on Dth

...DTH (Direct To Home) is the transmission mode by which satellite TV programming can be received at home. Currently there are six main DTH providers in India, namely Dish TV, TataSky, Big TV, Airtel Digital, Sun Direct and Videocon D2H. Direct To Home (DTH) is the primary alternative if you don’t want to depend on local cable operators. We frequently face Cable TV outages and breakdowns and in most cases the service is not dependable. Since DTH signals come directly from the broadcast satellite to the consumer’s dish, it can even reach remote places without any cable running through the streets and highways. With the widespread implementation of Conditional Access System (CAS) throughout India, DTH is a good alternative. Having many service providers makes it difficult to choose from. To select a DTH provider, we have to consider various factors such as picture quality, transmission during rough weather, suitability of the plans / packages, package pricing, and other value added services. The DTH service quality depends on the signal strength, so it is always better to check for excellent reception in your area. DTH services offer MPEG4 quality or DVD quality or MPEG4 with DVB-S2 digital transmission. MPEG4 with DVB-S2 (Digital Video Broadcasting) has provision for HD quality, but not implemented yet. It also allows for enhanced interactive services with access to the Internet. Airtel and Videocon offer MPEG4 with DVB-S2. Almost each DTH provider has special packs for the......

Dth and Digital Cable

...DTH vs Digital Cable TV Comparison: Which One is Better? As a consumer, you should choose your service provider wisely which will benefit you in the long run. The cable TV arrived few decades ago and replaced TV Antennaswhen they were used for receiving the television transmission. The cable TV operators offered many channels and the set up includes huge dish shaped antennas that are placed on top of the cable operator’s office or house. Customers were able to get a connection by paying a deposit and a monthly subscription charges. This set up includes the laying of cables through narrow streets and pathways alongside buildings. Any disruption to service due to rain or other reason led to poor signals transmission. Around 90 million television analog signals in India will have to be converted into digital signals in four phases as per the Cable Television Networks (CTN) Amendment Bill 2011. India's four metros - Delhi, Mumbai, Chennai and Kolkata - will replace all analog television networks with digital transmission from July 1, 2012. After this, the target will be 38 cities with a population above 10 lakh each and finally the rest of India. This has led to a rush between multi-system operators (MSOs) and DTH operators, to grab business opportunities and acquire a large subscriber base. With digitization of cable services, cable operators need to carry only digitized signals. An STB for decoding in digital format is required to get these digitized signals. Cable......
