Broadcast Television System
The Broadcast Television System is the method used to transmit television signals over the airwaves, cable, or satellite so viewers can watch TV. It involves converting video and audio into electronic signals, then encoding and modulating them so they can be transmitted efficiently across different channels. Once received by a TV or tuner, these signals are demodulated and decoded back into images and sound. Different systems, like NTSC, PAL, and ATSC, have been used historically worldwide, defining how signals are formatted and synchronized to ensure clear, reliable picture and sound quality on your television.
