Interpreting the catalog of digital TV, digital TV classification

The signal propagation distance on the ground is narrow, the anti-interference ability is poor, and the signal propagation distance of the satellite is wide, the anti-interference ability is strong, and there are many programs!

The cable signal propagation distance is long, the anti-interference ability is stronger than that of terrestrial wireless propagation, and the programs are also relatively rich.

This book includes five parts: basic knowledge of digital television, digital television source and channel technology, digital television receiver and display, digital television equipment interface, digital television image quality and measurement, etc., and gives a detailed explanation of the basic concepts of digital television, digital television system and related technologies.

According to the spatial propagation mode of signal, digital television mainly includes four forms: digital television terrestrial transmission system, digital cable television system, digital satellite television system, and IP digital television system.

A digital television system includes a front-end system, a transmission network, and a receiving terminal.

Digital signal analog technology for television.

It's just that you can watch back the shows you missed.

There are very few signal sources for televisions that receive digital signals, and there are few digital signal satellite TVs on satellites in China at present.

CCTV is an analog signal, digital TV is a digital signal, and digital TV has much higher image definition.

Of course, digital TV is good, and the digital age shows that human beings have progressed. Digital TV is all about digital.
