Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, [1] films, television programs, corporate conferencing, church services, and live theater productions. [2]

Contents

Audiovisual service providers frequently offer web streaming, video conferencing, and live broadcast services. [3] The professional audio visual industry has companies that provide both hardware, software and services. These organisations are commonly referred to as systems integrators and perform both the installation and integration of different types of AV equipment from multiple manufacturers into spaces to create the AV experience for the user.

Computer-based audiovisual equipment is often used in education, with many schools and universities installing projection equipment and using interactive whiteboard technology. [4]

Components

Aside from equipment installation, two significant elements of audiovisual are wiring and system control. If either of these components are faulty or missing, the system may not demonstrate optimal performance.

Wiring is a skill that not only requires proper cable rating selection based on a number of factors, including distance to the main rack, frequency and fire codes, but wires should also be out of sight, behind the walls and in the ceiling, when possible. System performance also depends on the integrity of the wires. If wires become exposed or mishandled during cabling, the signals may not transmit fluidly, which could compromise the quality. Wires should be neatly organized into the main component and properly labeled for easy reference.

Control refers to how the system will operate and how all the installed components will communicate. System automation devices from manufacturers like RTI, Crestron, Control4, AMX, Lightware and others are programmed to integrate the various components of the system and makes the system easy to use from various devices. For example, when programmed appropriately, a control system can allow a TV in zone one to automatically turn off when the music in zone two is turned on. Without proper control programming, the TV in zone one would stay on, even when the music in zone two is turned on.

Residential

Generally, residential audiovisual encompasses in-ceiling speakers, flat-panel TVs, projectors, and projector screens. This could include lighting, blinds, cinema rooms, etc. [5]

Commercial

The professional audiovisual industry is a multibillion-dollar industry, comprising manufacturers, dealers, systems integrators, consultants, programmers, presentations professionals, and technology managers of audiovisual products and services.

Commercial audiovisual can be a lengthy process to install and configure correctly. Boardroom audiovisuals can be installed for a number of reasons and often is due to the executives of the organization or business needing to have meetings with colleagues, customers and suppliers around the world. When creating an array of boardrooms for customers it beneficial to balance the pattern from the audio and microphone so there is no degradation in sound quality for the individuals listening. [6]

The proliferation of audiovisual communications technologies, including sound, video, lighting, display, and projection systems is evident in many sectors of society. This includes business, education, government, the military, healthcare, retail environments, worship, sports and entertainment, hospitality, restaurants, and museums. The application of audiovisual systems can be found in collaborative conferencing (which includes video-conferencing, audio-conferencing, web-conferencing, and data-conferencing), presentation rooms, auditoriums and lecture halls, command and control centers, digital signage, and more. Concerts and corporate events are among the most obvious venues where audiovisual equipment is used in a staged environment. Providers of this type of service are known as rental and staging companies, although they may also be served by an in-house technology team (e.g., in a hotel or conference center).

<span class="mw-page-title-main">Home cinema</span> Home entertainment system that aims to replicate the experience of a movie theater

A home cinema, also called a home theater or theater room, is a home entertainment audio-visual system that seeks to reproduce a movie theater experience and mood using consumer electronics-grade video and audio equipment and is set up in a room or backyard of a private home. Some studies show that films are rated better and generate more intense emotions when watched in a movie theater, but convenience is a major appeal for home cinemas. In the 1980s, home cinemas typically consisted of a movie pre-recorded on a LaserDisc or VHS tape; a LaserDisc Player or VCR; and a heavy, bulky large-screen cathode-ray tube TV set, although sometimes CRT projectors were used instead. In the 2000s, technological innovations in sound systems, video player equipment, TV screens and video projectors have changed the equipment used in home cinema set-ups and enabled home users to experience a higher-resolution screen image, improved sound quality and components that offer users more options. The development of Internet-based subscription services means that 2020s-era home theatre users do not have to commute to a video rental store as was common in the 1980s and 1990s.

<span class="mw-page-title-main">AV receiver</span> Consumer electronics component

An audio/video receiver (AVR) or a stereo receiver is a consumer electronics component used in a home theater or hi-fi system. Its purpose is to receive audio and video signals from a number of sources, and to process them and provide power amplifiers to drive loudspeakers, and/or route the video to displays such as a television, monitor or video projector. Inputs may come from a TV, FM, or AM tuner, satellite receiver, DVD players, Blu-ray Disc players, VCRs or video game consoles, among others. The AVR source selection and settings such as volume, are typically set by a remote controller.

Audio-to-video synchronization refers to the relative timing of audio (sound) and video (image) parts during creation, post-production (mixing), transmission, reception and play-back processing. AV synchronization can be an issue in television, videoconferencing, or film.

Document cameras, also known as visual presenters, visualizers, digital overheads, or docucams, are high-resolution, real-time image capture devices used to display an object to a large audience, such as in a classroom or a lecture hall. They can also serve as replacements for image scanners. Similar to opaque projectors, document cameras can magnify and project the images of actual, three-dimensional objects, as well as transparencies.

<span class="mw-page-title-main">Video design</span> Creative field of stagecraft

Video design or projection design is a creative field of stagecraft. It is concerned with the creation and integration of film, motion graphics and live camera feed into the fields of theatre, opera, dance, fashion shows, concerts and other live events. Video design has only recently gained recognition as a separate creative field. For instance, United Scenic Artists' Local 829, the union representing designers and scenic artists in the US entertainment industry, only added the Global Projection Designer membership category in 2007. Prior to this, the responsibilities of video design would often be taken on by a scenic designer or lighting designer. A person who practices the art of video design is often known as a Video Designer. However, naming conventions vary worldwide, so practitioners may also be credited as Projection Designer, "Media Designer", Cinematographer or Video Director. As a relatively new field of stagecraft, practitioners create their own definitions, rules and techniques.
