Modern digital broadcasting systems are complex hardware systems that include a number of devices that perform special functions. One of these devices is a receiver that receives and converts a signal for its subsequent transmission to the screen of a broadcasting device, which may be a TV or a personal computer display.
To transmit the television signal received by the decoding device (receiver), MPEG-2 or MPEG-4 compression technologies are used. The receiver converts the signal in accordance with the specified settings and transfers it to the digital TV screen, which allows you to see a high-quality picture and perceive sound without distortion. Most of the issues related to the operation of receivers come down to the choice of the type of connection and its adjustment. The receiver can be connected in one of the following ways: - to cable TV networks; - to a satellite dish; - to a computer network (for example, via WiFi) - to terrestrial digital television. The quality of the receiver is primarily determined by its correct connection. For video, the following connection options are available: HDMI, S-video, RF, Component and Composite. Select HDMI, optical digital, or analog RSA for audio. The easier it is to connect the receiver to an end device, the less likely it is to malfunction. It is best to use the option with the least amount of connecting wires, which is easy to use and easy to set up. When choosing wires to connect the receiver to a computer or TV, do not try to save on price, but avoid using connections with excess wire length. The short wire gives less signal distortion. The ideal wire is long enough to easily check the connection to the computer by removing the system unit from the rack. Receivers with a built-in RF modulator should be connected to the antenna input of the receiver with a suitable TV cable. In this case, the signal is transmitted at the frequency of one of the available UHF broadcast channels. This method is suitable for most older TVs with antenna input only.
