Problems solved by technology

[0005] 1. The one-way nature of the broadcasting system makes it impossible for broadcasting stations to know what programs users need
[0006] 2. The broadcast system cannot send the program to the users who want to watch it in a timely manner, and the users must watch it according to the program list
[0007] 3. The video-on-demand system can send the content required by the user to the user in time, but the limited bandwidth among its users competes, and the phenomenon of "multiple people and network congestion" is very serious
If a video service provider wants to provide a large number of users to watch at the same time, its operating costs will be very high
