Audio-visual
From Wikipedia, the free encyclopedia
The term audio-visual (AV) may refer to works with both a sound and a visual component, the production or use of such works, or the equipment involved in presenting such works. Movies and television shows are examples of audio-visual presentations.
Business presentations are also usually audio-visual. In a typical presentation, the presenter provides the audio by speaking, and supplements it with a series of images projected onto a screen, either from a slide projector, or from a computer connected to a projector using software such as PowerPoint. Audio-visual is used usually as industry jargon, expressing works with a type of visual and/or audio format. Most work today with AV is in the industry of movies, and usually now deals with digital technology.
