Does the hotel's IPTV TV system need to be customized? Why is it different from ours? It has many functions.

What they said is wrong. This is not the function of hotel customization, but the service providers advertise through the hotel's TV system. They want to pay advertising fees for hotels or operators (such as telecom and mobile).

Obviously, people won't ask you to play this advertisement on TV at home. Why? Because your TV is watched by your family, there is no ratings. Under normal circumstances, your TV is not willing to watch advertisements every day.
