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.[1]

Duties

[edit]

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.[2][3]

Titles

[edit]

Broadcast engineers may have varying titles depending on their level of expertise and field specialty. Some widely used titles include:

Qualifications

[edit]

Broadcast engineers may need to possess some or all of the following degrees, depending on the broadcast technical environment. If one of the formal qualifications is not present, a related degree or equivalent professional experience is desirable.

Knowledge

[edit]

Broadcast engineers are generally required to know the following areas, from conventional video broadcast systems to modern Information Technology:

Above mentioned requirements vary from station to station.

Digital engineering

[edit]

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.[4] 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 know-how.[5]

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.

Historical Evolution

The origins of broadcast engineering trace back to the late 19th century with Guglielmo Marconi's pioneering work in wireless communication. In 1895, Marconi successfully transmitted the first wireless signal using radio waves, laying the groundwork for radio technology. By 1901, he achieved the first transatlantic radio transmission, demonstrating the potential for long-distance broadcasting. The development of amplitude modulation (AM) in the early 20th century enabled voice and music transmission, culminating in the first scheduled AM radio broadcast on November 2, 1920, by station KDKA in Pittsburgh, which aired live election results. This event marked the birth of commercial radio broadcasting in the United States. Television engineering emerged in the 1930s and 1940s as an extension of radio principles, with the establishment of broadcast standards to ensure compatibility and quality. In the United States, the developed the first monochrome television standard in 1941, specifying 525 lines and 30 frames per second for analog transmission. Commercial television broadcasting began experimentally in the late 1930s, but widespread adoption was delayed by . Key regulatory milestones included the creation of the in 1934, which oversaw spectrum allocation and licensing for both radio and emerging television services. Post-, television expanded rapidly; by 1950, approximately 6 million TV sets were in American homes, growing to over 60 million by 1960, driven by economic prosperity and network infrastructure development. The analog-to-digital transition accelerated in the late , with the U.S. mandating a full switch to by June 12, 2009, to free up spectrum and improve signal quality. Technological shifts in the mid-20th century transformed broadcast systems from bulky, power-intensive designs to more efficient and versatile ones. The invention of the transistor in 1947 led to its adoption in broadcasting equipment during the 1950s, replacing vacuum tubes and enabling smaller, more reliable transmitters and receivers that reduced costs and improved portability. Color television standards, building on the NTSC framework, were approved in 1953, with widespread adoption in the 1960s as networks like NBC increased color programming; by the end of the decade, color sets comprised a significant portion of new sales, enhancing visual fidelity for viewers. Satellite broadcasting began in the 1960s with the launch of Telstar in 1962, the first active communications satellite, which relayed the initial transatlantic television signals and paved the way for global distribution networks. In recent decades, broadcast engineering has focused on digital enhancements and convergence with other technologies. The standard, approved by the FCC in 2017, introduces next-generation capabilities like 4K/8K video, interactive services, and mobile delivery, with voluntary rollout progressing through 2025; as of October 2025, more than 125 television stations in 80 markets are broadcasting , reaching approximately 75% of U.S. viewers, as broadcasters upgrade infrastructure for improved efficiency and viewer engagement.

Education and Qualifications

Essential Knowledge Areas

Broadcast engineers must possess a strong foundation in electromagnetics, which governs the behavior of electromagnetic waves used in radio and television transmission. This includes understanding wave propagation characteristics, such as reflection, refraction, and diffraction, which are essential for designing effective broadcast systems. Signal theory forms another core pillar, encompassing the analysis of analog and digital signals, including modulation and demodulation processes that ensure reliable information transfer over airwaves. Additionally, knowledge of audio and video encoding is critical, involving techniques to compress and represent multimedia data efficiently for transmission, as outlined in standards like those from the Digital Video Broadcasting Project. A fundamental grasp of amplitude modulation (AM) and frequency modulation (FM) principles is indispensable, as AM varies the carrier wave's amplitude to encode audio signals for medium-wave broadcasting, while FM alters the frequency for higher fidelity in VHF applications. Practical knowledge extends to RF propagation, where engineers analyze how radio waves travel through various environments, accounting for factors like and atmospheric conditions to predict signal coverage and mitigate interference. Basic antenna design principles are equally vital, focusing on elements such as patterns, gain, and to optimize signal and reception in broadcast setups. correction in transmission represents a key practical area, employing techniques like (FEC) codes—such as Reed-Solomon or convolutional codes—to detect and repair data errors caused by or during over-the-air delivery. Regulatory awareness is integral, particularly regarding spectrum allocation, where international bodies assign frequency bands to broadcasting services to prevent interference, as detailed in . Licensing requirements ensure compliance with these allocations, mandating engineers to adhere to procedures for obtaining transmission permissions from national authorities like the FCC. Safety protocols for high-power transmitters emphasize limiting radiofrequency exposure to protect workers and the public, following guidelines that include controlled access to transmitter sites and RF field strength limits. Integrating enhances technical expertise; problem-solving in real-time environments enables engineers to diagnose and resolve transmission faults swiftly, often under tight deadlines during live broadcasts. Basic skills facilitate coordinating equipment upgrades or facility installations, ensuring efficient resource allocation and timeline adherence in dynamic broadcast operations.

This process ensures professionals stay current with innovations, such as IP-to-5G transitions, through programs like SMPTE's boot camps on IP networking, which include modules on emerging applications. Failure to recertify may limit access to senior roles, underscoring the need for ongoing training amid industry shifts.

Core Technologies

Analog Systems

Analog broadcasting systems represent audio, video, and data through continuous waveforms that vary in , , or phase to encode information, distinguishing them from digital methods that use discrete binary states. In radio transmission, (AM) superimposes the audio signal onto a by varying its , while (FM) alters the carrier's frequency proportionally to the audio input for improved noise resistance. For television, vestigial (VSB) modulation is employed, where a portion of one is suppressed to conserve bandwidth while transmitting the full video signal via on a carrier, typically occupying 6 MHz channels. These techniques enable the over-the-air of analog signals but require precise carrier at the receiver to extract the original content. Central to analog broadcast infrastructure are transmitters that amplify and modulate the baseband signals for radiation, modulators that perform the core encoding (such as AM or FM exciters), and demodulators in receivers that reverse the process to recover the original waveform. Coaxial cabling serves as a primary transmission medium within studios and to antennas, providing low-loss transport of high-frequency signals up to several GHz with impedance matching at 75 ohms for video applications. Antenna systems, often designed for omnidirectional coverage in broadcasting, include towers with dipoles or collinear arrays tuned to the operating frequency, ensuring efficient radiation patterns over wide areas while minimizing multipath distortion. These components form a chain from signal generation to propagation, with power amplifiers in transmitters capable of outputs from kilowatts to megawatts for regional coverage. Key standards shaped analog broadcasting's implementation, such as the introduction of FM stereo in 1961, when the U.S. authorized a multiplex system allowing simultaneous left and right audio channels within a 200 kHz FM channel, using a 19 kHz pilot tone for stereo decoding. In television, the format adopted in the United States specified 525 horizontal lines per frame at 30 frames per second (interlaced), with and signals combined in a 6 MHz vestigial channel for compatibility with black-and-white receivers. These standards facilitated widespread adoption, with FM stereo enhancing audio fidelity for music broadcasting and NTSC enabling color TV from the 1950s onward. Despite their historical dominance, analog systems exhibit significant limitations, including high susceptibility to noise and interference, where degrades signal-to-noise ratios, manifesting as static in audio or in video. Interference from atmospheric conditions, electrical equipment, or adjacent channels further distorts waveforms, as analog modulation lacks correction inherent in digital schemes. These vulnerabilities, coupled with inefficient utilization—such as AM's 10 kHz per channel for monaural audio—drove the global phase-out of analog terrestrial , with many transitions completed in the and early , though some countries continue ASO into late 2025 to free for mobile and digital services.

Digital Transitions and Innovations

The transition to digital broadcasting represented a fundamental shift in broadcast engineering, driven by the need for improved signal quality, spectrum utilization, and new service capabilities. Beginning in the 1990s, this evolution involved the development and adoption of digital standards for both radio and television, culminating in widespread analog switch-offs globally. For digital radio, the Digital Audio Broadcasting (DAB) standard, standardized by the European Broadcasting Union (EBU) and the International Telecommunication Union (ITU), enabled CD-quality audio and data services over terrestrial networks. In the United States, HD Radio, developed by iBiquity Digital Corporation and approved by the Federal Communications Commission (FCC), provided in-band on-channel digital transmission compatible with existing analog FM signals. For television, Europe's Digital Video Broadcasting (DVB) family of standards, including DVB-T for terrestrial delivery, facilitated high-definition services across the continent. Similarly, the Advanced Television Systems Committee (ATSC) standard was implemented in the US, supporting digital terrestrial television (DTT) with enhanced resolution and multiplexing. A key milestone was the analog switch-off (ASO) process, where the ITU defined ASO as the shutdown of analog transmissions once digital signals achieved sufficient coverage. In Europe, the European Union recommended completing the switch-off by 2012 to free up spectrum for digital services and mobile broadband. By the mid-2010s, over 50 countries had completed their ASO, releasing the "digital dividend" spectrum in the 700-800 MHz bands for other uses. Central to these digital systems are key technologies that enable efficient transmission and reception. MPEG compression standards, particularly MPEG-2 for initial digital TV and later MPEG-4/AVC for high-definition content, reduce video data rates while maintaining quality, allowing multiple channels within the same bandwidth as a single analog signal. For robust mobile reception, Coded Orthogonal Frequency Division Multiplexing (COFDM) modulation is employed in standards like DVB-T and the newer ATSC 3.0, dividing the signal into multiple subcarriers to mitigate multipath interference and Doppler effects in moving environments. As of late 2025, ATSC 3.0 deployment in the United States has reached approximately 80% population coverage, supporting enhanced features such as 4K UHD, HDR, and interactive services. Complementing terrestrial delivery, IP-based protocols such as HTTP Live Streaming (HLS) and Dynamic Adaptive Streaming over HTTP (DASH) facilitate hybrid broadcast-broadband services, enabling adaptive bitrate streaming over IP networks for seamless integration with online content. These technologies support datacasting, where broadcasters transmit non-audio/video data like traffic updates or software updates alongside primary content. Recent innovations have further advanced , particularly in video quality and delivery paradigms. Ultra-high definition (UHD) television, encompassing 4K (3840x2160 resolution) and 8K (7680x4320), has gained traction through recommendations, with trials demonstrating enhanced detail for large-screen viewing. (HDR) standards, such as and Hybrid Log-Gamma (HLG), expand color gamut and contrast, improving visual fidelity in both broadcast and over-the-top (OTT) platforms like and , where integration allows unified workflows for linear and on-demand content. As of 2025, 5G-enabled broadcasting leverages specifications for low-latency streaming, achieving low end-to-end delays, with demonstrations reaching under 100 ms for live events via and delivery, enhancing remote production and interactive applications. The benefits of digital transitions include substantial improvements in spectrum efficiency, with digital signals requiring up to six times less bandwidth per channel compared to analog, enabling simulcasting and additional services. through datacasting supports features like electronic program guides and , while higher audio/video quality enhances viewer engagement. However, challenges persist, including high infrastructure costs for transmitter upgrades and spectrum reallocation, estimated at billions globally during ASO phases, alongside the need for consumer device compatibility to avoid access disparities. These advancements continue to evolve, balancing efficiency gains with deployment hurdles in diverse regulatory environments.
