Broadcast television services transmit audio and video signals over the airwaves to reach a wide audience. Here is some general information about these services:
- Broadcast Television:
Broadcast television is the distribution of television content over the airwaves using radio frequency signals. This means that viewers can receive and watch television channels for free using a TV set with an antenna, without the need for a cable or satellite subscription.
Satellite And Terrestrial Broadcast
Satellite and terrestrial broadcast services are two different ways of transmitting audio and video signals to reach a wide audience. Here is some general information about these services:
- Satellite Broadcast Service:
Satellite broadcast services use geostationary satellites orbiting the Earth to transmit audio and video signals to a wide coverage area. These signals are received by satellite dishes and converted into TV or radio content.
Satellite broadcast services offer a wider coverage area than terrestrial services and are more suitable for reaching remote or hard-to-reach areas. However, they require a satellite dish and a satellite receiver, which can be more expensive than the equipment needed for terrestrial services.
- Digital Terrestrial Television Services:
Digital terrestrial television (DTT) services are television broadcasts that are transmitted over the airwaves using digital signals, rather than the analog signals used by traditional broadcast television.
DTT offers several advantages over analog broadcasting, including improved picture and sound quality, greater channel capacity, and more efficient use of broadcast spectrum. With digital broadcasting, broadcasters can transmit more channels and additional services, such as electronic program guides and interactive features.
To receive DTT, viewers will need a digital television set or a set-top box that can decode digital signals. In many countries, governments have mandated the switch from analog to digital broadcasting and have provided subsidies or support to help viewers upgrade their equipment.
