Why are there so many TVs backstage in the news broadcast? What's the use of playing so much TV?

Because the camera is only aimed at the host, the news content has been edited in advance. After the host finishes the news content, the director (director: the person who controls the whole program and gives orders) will instruct the staff to switch the relevant screens. If it's other TV stations, aren't there commercials? The content played by each small TV is different, and the staff will switch pictures at an appropriate time (you should have seen that the host made one thing clear, but what you saw on TV was an own goal of another thing, because the staff switched the pictures wrong) .................................................................................................................

In fact, many programs are being recorded now, but the news will not be broadcast again because of its timeliness (new) ... and some people who have heard the news break are sent because of the video of the news event, which is temporary (the host always takes the headset to receive the instructions from the guide room).

There is a mistake on the second floor. Not different channels, but what will be broadcast on the same channel for a period of time. ....
