Previously, coaxial cables left over from cable television were not used to install antennas on rooftops. Some larger companies and institutions established their own television channels (such as university stations, coal mine stations, and Lai Gang station). Before and after the Beijing Olympics, China Central Television (CCTV) began promoting DVB set-top boxes, using coaxial cables to transmit digital signals. These set-top boxes could be used to watch on-demand programs and purchase paid content. CCTV also started providing internet services during this period. At that time, households purchased "broadband," which could only be used to view web pages and images, and was often unstable.Fortunately, the local television company had a skilled technician who set up an FTP server. I could tell him what movies I wanted to watch, and he would download them and store them on the server, which helped retain some customers.Furthermore, I haven't had time to watch TV recently, and I don't know what happened afterward. However, I do know that a few years ago, these coaxial cables were removed and replaced with fiber optic cables.
Fiber optic is still better.
(The WeChat input method is so annoying! I clearly saw that the first suggested word for "guang'xian" was "fiber optic," but as soon as I selected it, the suggestions changed to "light.")
