television broadcasting

Television broadcasting is the process of transmitting visual and audio signals from a source to viewers' TVs over a shared medium, such as radio waves, cable, or satellite. Content is produced by broadcasters, encoded into electronic signals, and then sent through transmitters or service providers. These signals travel through air or cables to reach viewers' receivers, which decode them into images and sounds displayed on the screen. This system allows for the widespread, real-time distribution of entertainment, news, and information to audiences in homes and public venues worldwide.
