AV-over-IP is the distribution of audio and video signals as data packets over an Ethernet network, replacing point-to-point AV cabling and matrix switchers with encoders, decoders and network switches.
Encoders convert a source — a laptop, camera or media player — to a network stream; decoders at displays convert it back. Because routing happens on the network, any source can reach any display the network reaches, which makes AV-over-IP well suited to multi-floor offices, lobby signage, overflow rooms and video walls.
Systems use different technologies and compression approaches (for example Dante for audio, and SDVoE or IPMX-based approaches for video). Network design — bandwidth, multicast, VLANs and quality of service — must be planned with IT before installation.
