Satellite TV receiver refers to the electronic equipment that converts the output signal of satellite down converter lNB into audio and video signals. Satellite TV receiver belongs to electronic tuning channel selector, which has the advantage of saving spectrum resources. Its system principle is to use geosynchronous satellites. The principle is that satellite signals are reflected by satellite photos in the form of electromagnetic waves and focused on the feed and tuner, and then input into TV through denoising, decoding, coding and other steps.
However, because this satellite pot does not use technology, its selection of receiving signals is not judgmental. The received signal is complicated, and some foreign signals may be received. However, foreign countries are more enlightened. Some minors in our country watch some TV programs such as bloody violence, which will affect the physical and mental health of teenagers. In addition, the state explicitly prohibits the installation of satellite cookers. Radar tanks are becoming less and less common now.
