AES67 — Audio over IP Interoperability Standard
AES67 is the SMPTE/AES standard for interoperable audio over IP, defining RTP transport, PTP clocking, and SDP/SAP discovery so that Dante, Ravenna, Livewire, and Q-LAN devices can exchange audio across platforms.
Dante — Digital Audio Network Transport
Industry-standard audio networking protocol by Audinate carrying uncompressed multi-channel digital audio over standard Gigabit Ethernet with sub-millisecond latency.
IGMP — Internet Group Management Protocol
IGMP controls multicast group membership on Ethernet networks — required for Dante audio and AV-over-IP video to work correctly without flooding every switch port with unwanted traffic.
Latency and Jitter — AV Network Timing
Latency is the delay from source to destination; jitter is the variation in that delay — both critically affect live audio, video conferencing, and AV-over-IP systems.
PTP — Precision Time Protocol (IEEE 1588)
PTP (IEEE 1588) synchronizes clocks across a network to sub-microsecond accuracy — essential for Dante, AES67, AV-over-IP, and any system where audio or video devices must share a common time reference.
QoS — Quality of Service
QoS prioritizes time-sensitive AV traffic (Dante audio, AV-over-IP) over bulk data on shared networks, preventing dropouts caused by congestion from IT traffic.
RTP and RTSP — Real-Time Transport Protocols
RTP carries real-time audio and video over IP networks; RTSP controls the playback of those streams — together they underpin Dante, AES67, IP camera streaming, and IPTV in AV systems.
VLAN — Virtual Local Area Network
VLANs segment a physical network into isolated Layer 2 broadcast domains — essential for separating AV, IT, and control traffic while sharing common switch infrastructure.
