Field of engineering dealing with radio and television broadcasting

Broadcast engineering or radio engineering is the field of electrical engineering, and now to some extent computer engineering and information technology, which deals with radio and television broadcasting. Audio engineering and RF engineering are also essential parts of broadcast engineering, being their own subsets of electrical engineering. Broadcast engineering involves both the studio and transmitter aspects (the entire airchain), as well as remote broadcasts. Every station has a broadcast engineer, though one may now serve an entire station group in a city. In small media markets the engineer may work on a contract basis for one or more stations as needed.

Modern duties of a broadcast engineer include maintaining broadcast automation systems for the studio and automatic transmission systems for the transmitter plant. There are also important duties regarding radio towers, which must be maintained with proper lighting and painting. Occasionally a station's engineer must deal with complaints of RF interference, particularly after a station has made changes to its transmission facilities.

The conversion to digital broadcasting means broadcast engineers must now be well versed in digital television and digital radio, in addition to analogue principles. New equipment from the transmitter to the radio antenna to the receiver may be encountered by engineers new to the field. Furthermore, modern techniques place a greater demand on an engineer's expertise, such as sharing broadcast towers or radio antennas among different stations (diplexing). Digital audio and digital video have revolutionized broadcast engineering in many respects. Broadcast studios and control rooms are now already digital in large part, using non linear editing and digital signal processing for what used to take a great deal of time or money, if it was even possible at all. Mixing consoles for both audio and video are continuing to become more digital in the 2000s, as is the computer storage used to keep digital media libraries. Effects processing and TV graphics can now be realized much more easily and professionally as well. With the broadcast industry's shift to IP based production and content delivery technology not only the production technology and workflows are changing, but also the requirements for broadcast engineers, which now include IT and IP networking knowhow. Other devices used in broadcast engineering are telephone hybrids, broadcast delays, and dead air alarms. See the Glossary of electrical and electronics engineering for further explanations.

In the United States, many broadcast engineers belong to the Society of Broadcast Engineers (SBE). Some may also belong to the Society of Motion Picture and Television Engineers (SMPTE), or to organizations of related fields, such as the Audio Engineering Society or Institute of Electrical and Electronics Engineers (IEEE) IEEE Broadcast Technology Society (BTS). For public radio, the Association of Public Radio Engineers was created in late May 2006.
