Audiovisual

Audiovisual (AV) refers to technologies and materials that involve both sound and vision used to record, reproduce, or transmit information and entertainment.

Core components include audio devices (microphones, amplifiers, loudspeakers, mixers), visual devices (cameras, displays, projectors, video walls), and supporting infrastructure (cables, control systems, networking).

AV technology has evolved from analog media such as film projectors, phonographs, and slide projectors to digital media and networked systems that integrate across devices.

Applications include education and training, corporate presentations, live events, broadcasting, film and music production, museums, retail displays, and home entertainment.

Interoperability and standards include connection interfaces (HDMI, SDI), wireless protocols, and file formats; accessibility considerations like captions and audio description.

Many contemporary AV systems emphasize integration with information technology, enabling streaming, conferencing, and remote collaboration.
