how do TVs work


I just don’t understand how in every tv can access the same information and display it the same with the lcds inside working together

In: Technology

The question is vague. Broadcast TV is just like broadcast radio with the addition of pictures. There’s a high power transmitter sending the signal across an entire metropolitan area. Each transmitter in a city uses a different frequency. The receiver tunes to the desired frequency.

The question is too vague sorry.

Are you asking how the display works?
Are you asking how cable/antenna works?
Are you asking how Smart TVs are interactive?
