We urgently need the solution of "hotel TV signal". This hotel has 30 rooms. How to realize watching TV in every room with the most economical scheme?

If there are 100 rooms, it is suggested to apply for 30 digital TV set-top boxes as front-end signal sources of TV broadcasting in the front-end computer room of digital TV transformation, and then with the help of digital TV front-end transformation equipment such as modulators, mixers and power amplifiers, the TV viewing problem of 100 rooms can be solved. 100 room can enjoy programs played by 30 set-top boxes (one set-top box controls the output of a program). In this way, the original application for 100 digital TV broadcast set-top boxes only needs 30, which not only saves 70 digital TV set-top boxes, but also saves the viewing fee of 12 months every year, such as the viewing fee of set-top boxes in 25 yuan for one month (70 * 25 * 12 = 2 1000). And you can also use your own digital TV front-end, transform the computer room TV network, and increase the advertising of your own hotel chain. You can also use the free TV signal source to enrich your hotel room TV signal.
