AV is everywhere.

You can find AV technology in meeting rooms, classrooms, boardrooms, conference halls, cinemas, stadiums, airports, museums, retail stores, broadcast studios, control rooms, houses of worship, hotels and live events.

But what exactly does AV mean?

What is the full form of AV? What does an AV company do? What is an AV integrator? What jobs are available in AV? What is an AV room? And how can someone start a career in the AV industry?

This complete guide explains AV, or audiovisual technology, from the basics to the professional AV industry.

What Does AV Mean?

AV means Audiovisual.

The term combines two fundamental forms of communication:

Audio — sound, speech, music and other audible information
Visual — images, video, graphics and other visual information

An AV system combines technologies that allow people to create, process, distribute, display, hear, control and interact with audio and visual information.

In professional environments, AV is much more than a television, projector or microphone.

A modern AV system can include:

Microphones
Speakers
Amplifiers
Digital Signal Processors (DSP)
Cameras
Displays
Projectors
LED walls
Video processors
Matrix switchers
AV over IP systems
Control systems
Video conferencing systems
Digital signage
Streaming systems
Network switches
Structured cabling
Collaboration platforms

Modern AV sits at the intersection of technology, content and physical space.

What Is the Full Form of AV?

The most common full form of AV is Audiovisual.

You may also see AV written as:

AV
A/V
Audio Visual
Audiovisual
Pro AV
Professional AV

In the professional technology industry, Pro AV generally refers to professional audiovisual systems designed for commercial, institutional, entertainment or specialized environments.

For example, a corporate meeting room with microphones, speakers, cameras, displays and a video conferencing system is a professional AV environment.

What Exactly Is AV?

AV is a technology ecosystem used to communicate information through sound, images, video and interactive experiences.

A simple audio system may look like:

Microphone → DSP → Amplifier → Speaker

A simple video system may look like:

Camera → Video Processing → Display

A complete meeting room could combine:

Microphone + Camera + Laptop + Network + DSP + Display + Speakers + Control System

The objective of AV is not simply to connect equipment.

The real objective is to create a system that allows people to:

Communicate
Collaborate
Present
Learn
Share information
Entertain
Monitor
Interact

This is why professional AV involves engineering, networking, acoustics, control, software, content and user experience.

What Does “AV Video” Mean?

The phrase “AV video” is commonly used when people search for audiovisual video technology.

Technically, the phrase is somewhat repetitive because AV already means Audiovisual.

However, in practical usage, AV video can refer to:

Video signals
Video distribution
Video conferencing
Camera systems
PTZ cameras
Video switching
Video processing
Video walls
Displays
HDMI systems
SDI systems
NDI systems
AV over IP
Digital signage

For example:

Camera → HDMI/SDI/NDI → Switcher → Processor → Display

In professional AV, video is usually only one part of the overall system. Audio, control, networking and user experience are equally important.

What Is an AV System?

An AV system is a combination of audiovisual equipment, software, infrastructure and control technologies designed to achieve a specific communication, collaboration, learning, entertainment or operational objective.

Example: Corporate Meeting Room

A modern meeting-room AV system may contain:

System	Example
Camera	PTZ camera
Microphone	Ceiling microphone
Audio processing	DSP
Speaker	Ceiling speaker
Display	Professional display
Video	HDMI / USB / Network video
Collaboration	Microsoft Teams / Zoom

When selecting an AV integrator, consider:

Project experience
Technical expertise
Certifications
Manufacturer partnerships
Geographic coverage
Service capability
Project management
Support capability
Previous installations

How Many AV Companies Are There?
