Question

is there any delay during live telecasts? if yes, why?

Answer 1

The radio and “over-the-air” broadcasts of decades ago were, in a way, more live than current live television. Seconds are often lost as broadcast signals are transferred and processed between stations, satellites, and other relays, creating unintentional lost time between the material and live viewing of it. These various transactions can each add seconds of delay, cumulatively creating unintentional delays that are longer than the intentional ones.
