You might think that there is only one type of satellite TV system ... but you are wrong. In fact, there are two different formats of satellite television: TeleVision Receive Only (TVRO) and Direct Broadcast Satellite (DBS). Each satellite TV system is built differently and functions in its own way. Dish Network, for example, is a DBS system. However, not all satellite TV systems are DBS.
Below is a breakdown of each system. Read this and get a better idea of the satellite TVRO TV and DBS systems.
TVRO - TeleVision only
TVRO was the first satellite system available for home viewing of satellite television. This required a robust, large dish with a diameter of 3 to 6 feet and worked in the C-Band. Frequencies around 4 G Hertz are called C-Band and require large dishes, because the wavelength of these frequencies is longer than in Ku-Band, which requires a much smaller plate about 18 inches in size. Ku-Band - from 12 to 14 G Hertz.
TVRO systems also need mobile ware because it needs to get all the channels of many satellites. C-Band satellites have much fewer channels than Ku-Band satellites, and therefore more satellites are required to ensure a sufficient number of channels. The possibilities that exist in TVRO systems are that you can also receive free channels and independent channels, for example, from news companies. For example, you can get unedited material that is broadcast from the news team somewhere in the satellite coverage area. They transmit their materials to their headquarters using the C-Band satellite. Many of these types of feed are not scrambled and are available to anyone with the appropriate equipment.
TVRO systems are often called Big Dish TV, C-Band Satellite TV and BUD (Big Ugly Dish).
DBS - direct broadcast satellite
Satellite TV via DBS is provided in Ku-Band. These satellites operate at higher frequencies and can transmit higher power signals. This means that much smaller dishes can be used to receive the signal. A small dish of 18 inches is already enough to get satellite TV on satellite TV. This allows you to have satellite TV from the apartment on the 10th floor, if you have a clear line of sight to the south. This is a system used by Dish Network and other satellite TV providers.
DBS for everyone. A satellite dish is so small that it is not an obstacle, for example, TVRO dishes from 3 to 6 feet. After installation, the dish does not need to be serviced, since it is intended only for one satellite. Some dishes actually have 2 or more channels, which allows you to receive signals from more than one satellite.
DBS satellites do not have free channels, since they are often owned and used by a satellite TV provider, for example, on the Dish Network, while TVRO satellites are often used by those who rent space on a satellite for a limited time. TVRO systems are designed, for example, to transport unedited materials between continents, but also on one continent.
DBS is designed for everyone with a simple and inexpensive installation of the system. Often installation is free because it is very easy to do. The only thing that is needed is to know a little where to find the satellite and the tools that make it even easier. A qualified installer will find a satellite and point it to maximum reception within a few minutes.
