Satellite Broadcasting Transmission Principles

The satellite broadcasting and television system consists of four main components: uplink transmitter stations, on-board transponders, measurement and control stations, and earth receiving stations.

Uplink transmitting station to the program production center to process the signals transmitted through the directional antenna to the satellite transmit uplink band signals; at the same time also receive from the downlink retransmitted by the weak microwave signals, monitoring the quality of the satellite relay program.

Star transponder star transponder is equivalent to the role of the space relay station to receive the uplink microwave signals from the ground uplink station and amplify it, frequency conversion, and then amplified to the ground service area.

The ground receiving station receives the signals from the satellite, after modulation to obtain the correct video signal and audio signal, directly to the TV monitor or TV set, reproduce color images and playback of the accompanying sound.

advantages of satellite broadcasting transmission

The advantages of satellite broadcasting transmission include good signal quality, simple digitization, maximum coverage area and freedom from geographical conditions, which determines that satellite broadcasting and television can serve all over the world and across geographical areas.

Nowadays, the satellite radio and television promotion business is moving forward with good prospects for development. In particular, the addition of digital technology has brought satellite radio and television into a brand new world, making satellite broadcasting multifunctional to be utilized, enabling the comprehensive exchange of information, and constantly making great contributions to the promotion of digital technology.
