System History

History of AV Systems

From analog audio-video chains to networked, software-driven experiences, AV evolved into intelligent collaboration platforms.

Overview

AV systems started with analog mixing, amplification, and distribution. Digital processing introduced DSPs, HDMI/SDI, and multi-format routing. The modern AV stack leverages IP transport, control systems, and cloud platforms for scalability.

Audio: DSPs, beamforming mics, acoustic tuning
Video: HDMI/SDI, IP encoders, scalers, KVM extensions
Control: automation, touch panels, occupancy sensors
Cloud: remote monitoring, updates, analytics

Timeline

1970s–1990s: Analog mixers, amplifiers, CRT projection
2000s: Digital signal processing, HD formats, matrix switchers
2010s: IP video transport, control integration, collaboration suites
2020s: AV-over-IP, cloud management, AI-assisted optimization
