Broadcast Television

Broadcast television is the sending of video and audio signals to devices (such as television sets) within a broadcast area that can receive the broadcast signals. Television broadcast technology was developed in the 1940s. The success of the television marketplace is due to standardized, reliable, and relatively inexpensive television receivers and a large selection of media sources. The first television transmission standards used analog radio transmission to provide black and white video service. These initial television technologies have evolved to allow for both black and white and color television signals, along with advanced services such as stereo audio and closed caption text. This was a very important evolution as new television services (such as color television) can be on the same radio channel as black and white television services.

Television systems initially used analog television technology. While analog television transmission provided relatively good video and audio signals, it does not easily allow the sending and receiving of multimedia signals and services. As a result, TV broadcast systems have been converted to use digital signal transmission. Each digital TV broadcast channel can provide several digital TV channels along with advanced television services.

New technologies allow transmission of high-definition television (HDTV). HDTV is the term used to describe a high-resolution video and high quality audio signal as compared to standard NTSC or PAL video transmission. HDTV signals can be in analog or digital form. Digital HDTV systems have the added benefits of providing data and other multimedia services.

This figure shows a television broadcast system. This television system consists of a television production studio, a high-power transmitter, a communications link between the studio and the transmitter, and network feeds for programming. The production studio controls and mixes the sources of information including videotapes, video studio, computer created images (such as captions), and other video sources. A high-power transmitter broadcasts a single television channel. The television studio is connected to the transmitter by a high bandwidth communications link that can pass video and control signals. This communications link may be a wired (coax) line or a microwave link. Many television stations receive their video source from a television network. This allows a single video source to be relayed to many television transmitters.
