a/v

Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services, and live theater productions.Audiovisual service providers frequently offer web streaming, video conferencing, and live broadcast services. 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.
