Broadcasting systems are methods used to transmit audio and video content to a wide audience. These systems can include traditional television and radio broadcasts, as well as digital platforms like streaming services. They work by sending signals over the airwaves or through cables, allowing people to receive content on various devices. There are two main types of broadcasting: terrestrial and satellite. Terrestrial broadcasting uses ground-based transmitters to send signals, while satellite broadcasting relies on satellites orbiting the Earth. Both systems aim to deliver entertainment, news, and educational content to viewers and listeners across different regions.
