To watch DVB-T TV programs, you need to install a DVB-T system locally. Now the provinces and cities that adopt this system standard are:
Guangdong (Guangzhou, Foshan, Shenzhen), Beijing, Shanghai, Changsha, Nanjing, Chongqing, Zhengzhou, Dalian, Jinan, Hangzhou, Wuhan, Hefei, Lanzhou and Nanjing. (Note: The above information comes from the Internet for reference only)

How much DVB-T digital TV can be received depends on how many DVB-T TV channels local TV stations can open. For example, you can receive 7 stops in Guangzhou and 3 stops in Shenzhen. Please note: DVB-T TV programs are different from home TV programs. So you can receive dozens of programs at home, while DVB-T digital TV can only receive a few. This is not the problem of TV box reception, but that there are too few local DVB-T channels. Similarly, the content of TV programs received depends on the TV station. In most cities, DVB-T TV mainly includes traffic, tourism, entertainment, news and other programs. For example, Guangzhou has special mobile TV channels: City Channel, Guangdong Mobile, Zhujiang Mobile and Guangzhou Mobile.
There is no charge for DVB-T digital TV! Now DVB-T TV programs are all public channels, mainly traffic information and news. The income of TV stations still comes from advertising, not TV program fees. All you need to spend is the cost of buying a DVB-T digital TV receiving box.
There are several possibilities: First, there may be no DVB-T TV channel in your location, or there may be a mobile TV channel in your location, but it is not a DVB-T system, so the TV box can't receive TV, so you must make sure the local opening situation before buying this product. Second, the signal problem. There may be obstacles where you are. Please drive to another location and test it again. Test it several times. DVB-T TV signal is limited by transmission area. If they exceed the transmission area, the information will be invalid and may not be received.

Questions about paid encrypted channels:
Encrypted channels are programs encrypted and scrambled by TV stations. The audience uses a special decoder to decrypt the watch, and charging the user is its profit model. Digital mobile TV receiver can be divided into encrypted CA player and free FTA player. At present, some areas also charge for the encryption of some broadcast terrestrial radio digital signals. Users need to use special decryption receivers and decryption cards, which are expensive and pay monthly viewing fees. Due to the different encryption systems in different places, encrypted reception can only receive specific encrypted programs.
