How to implement video broadcasting in school?

Question

Computer networks

Hello, I am faced with the task of implementing the following video broadcasting for the school:
1. Video was displayed on TVs according to the location of TVs and panels (that is, if the TV is hanging in the English corridor, then the video should be played in English);
2. There is a video recording studio for the implementation of "School Television", therefore, it is necessary to implement the display of online video broadcast on TVs;
3. In the future, it is planned to install an audio surround sound system to turn on background music during breaks and under the voice acting of TVs.
There are 6 TVs - NEC MultiSync V652, about 20 - TV LED LG 55LB650V, 2 interactive monitors with a minicomputer on board.
For NEC MultiSync V652 we plan to buy raspberry pi.
I do not know how to implement all this miracle. The network is completely built on CISCO equipment.

Answer 1

You are rich in school.
The question, as always, rests on the budget of the decision.
If you have money, then you can try to buy a couple of multichannel broadcast servers (not sdi, but ip).
There is already a question in the amount of diverse content (number of classes).
