Broadcast engineeringorradio engineeringis the field ofelectrical engineering,and now to some extentcomputer engineeringandinformation technology,which deals withradioandtelevisionbroadcasting.Audio engineeringandRF engineeringare also essential parts of broadcast engineering, being their ownsubsetsof electrical engineering.
Broadcast engineering involves both thestudioandtransmitteraspects (the entireairchain), as well asremote broadcasts.Everystationhas a broadcastengineer,though one may now serve an entire station group in a city. In smallmedia marketsthe engineer may work on acontractbasis for one or more stations as needed.[1]
Duties
[edit]Modern duties of a broadcast engineer include maintainingbroadcast automationsystems for the studio andautomatic transmission systemsfor the transmitterplant.There are also important duties regardingradio towers,which must bemaintainedwith properlightingandpainting.Occasionally a station's engineer must deal withcomplaintsofRF interference,particularly after a station has made changes to its transmission facilities.[2][3]
Titles
[edit]Broadcast engineers may have varying titles depending on their level ofexpertiseand field specialty. Some widely used titles include:
- Broadcastdesign engineer
- Broadcast Integration Engineer
- Broadcastsystems engineer
- BroadcastITengineer
- BroadcastITsystems engineer
- Broadcastnetwork engineer
- Broadcastmaintenance engineer
- Broadcast technician
- Videobroadcast engineer
- TV studiobroadcast engineer
- Outside broadcastengineer
- Remote broadcastengineer
Qualifications
[edit]Broadcast engineers may need to possess some or all of the followingdegrees,depending on the broadcast technical environment. If one of the formal qualifications is not present, a related degree or equivalent professional experience is desirable.
- Degree inelectrical engineering
- Degree inelectronic engineering
- Degree intelecommunications engineering
- Degree incomputer engineering
- Degree inmanagement information system
- Degree in broadcast technology
Knowledge
[edit]Broadcast engineers are generally required to know the following areas, from conventional video broadcast systems to modern Information Technology:
- Conventional broadcast
- Audio/Videoinstrumentationmeasurement
- Basebandvideo– standard /high-definition
- Broadcast studioacoustics
- Television studios- broadcastvideo camerasandcamera lenses
- Production switcher(Video mixer)
- Audio mixer
- Recording engineer
- Broadcast IT
- Video compression-DV25,MPEG,DVBorATSC(orISDB)
- Digital serverplayouttechnologies. -VDCP,Louth,Harris,control protocols
- Broadcast automation
- Disk storage–RAID/NAS/SANtechnologies.
- Archives –Tape archivesorgrid storagetechnologies.
- Computer networking
- Operating systems–Microsoft Windows/macOS/Linux/RTOS
- Post production–video captureandnon-linear editing systems(NLEs).
- RF
- RFsatellite uplinking– High-powered amplifiers (HPA)
- RFcommunications satellitedownlinking– Band detection,carrierdetection andIRDtuning, etc.
- RF transmitter maintenance - IOT UHF transmitters, solid-state VHF transmitters, solid-state MF transmitters (AM radio), tube type VHF, and MF transmitters. Antennas, transmission lines, high power filters, digital modulators, towers, tower lighting systems, and backup generators.
- Health and safety
- Occupational safety and health
- Fire suppressionsystems likeFM 200.
- Basicstructural engineering
- RFhazard mitigation
Above mentioned requirements vary from station to station.
Digital engineering
[edit]The conversion todigitalbroadcasting means broadcast engineers must now be well-versed indigital televisionanddigital radio,in addition toanalogueprinciples. New equipment from the transmitter to theradio antennato the receiver may be encountered by engineers new to the field. Furthermore, modern techniques place a greater demand on an engineer's expertise, such assharingbroadcast towersorradio antennasamong different stations (diplexing).
Digital audioanddigital videohave revolutionized broadcast engineering in many respects.[4]Broadcaststudiosandcontrol roomsare now already digital in large part, usingnon-linear editinganddigital signal processingfor what used to take a great deal of time or money, if it was even possible at all.Mixing consolesfor bothaudioandvideoare continuing to become more digital in the 2000s, as is thecomputer storageused to keep digital medialibraries.Effects processingand 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 includeITandIP-networkingknowhow.[5]
Other devices used in broadcast engineering aretelephone hybrids,broadcast delays,anddead airalarms.See theGlossary of electrical and electronics engineeringfor further explanations.
