Application of DVBS/S2 in digital TV system VIII (now popular dual tuner application)
Lao Xie in the field of digital television has been mixed for some years, "dvbs/s2 in the application of digital television system" series of articles, a brief introduction of a number of satellite receiving relevant knowledge points. Today Lao Xie continues to play waste heat, and wants to chat with friends about the most popular dual tuner applications in the h
Digital TV: A television system or television device that uses digital signals during processing, transmission, transmission, and receiving of television signals. A TV that can directly receive and process external digital TV signals is called a digital TV. A TV that receives analog TV signals and uses digital processing technology only in image restoration. It is often called "digital TV", but this is not a real digital TV.
The specific transmission process of digital TV is:Digital TV signals a
