Technical Glossary
AES (Audio Engineering Society Digital Audio)
Section titled “AES (Audio Engineering Society Digital Audio)”Digital audio format for stereo pairs.
Transmitted via XLR cables using AES3 standard.
Common in professional audio and broadcast facilities.
Dante (Digital Audio Network Through Ethernet)
Section titled “Dante (Digital Audio Network Through Ethernet)”Audio-over-IP protocol by Audinate.
Transmits multi-channel audio via standard Ethernet networks.
Widely adopted in broadcast, live sound, and installed audio systems.
Embedded Audio
Section titled “Embedded Audio”Audio channels embedded within video signals.
SDI typically carries 8 or 16 audio channels alongside video.
IP video standards (ST 2110) separate audio streams but logically embed them.
MADI (Multi-channel Audio Digital Interface)
Section titled “MADI (Multi-channel Audio Digital Interface)”Industry standard for transmitting up to 64 audio channels.
Single coaxial cable or fibre optic connection.
Commonly used in broadcast facilities for routing between equipment.
Milan (AVB)
Section titled “Milan (AVB)”Media-over-IP standard based on Audio Video Bridging (AVB).
Provides deterministic, low-latency audio/video transport over Ethernet.
Successor to earlier AVB implementations with stricter interoperability requirements.
NDI (Network Device Interface)
Section titled “NDI (Network Device Interface)”IP video protocol by NewTek (now Vizrt).
Transmits video, audio, and metadata over standard IP networks.
Popular in broadcast production and streaming workflows.
SDI (Serial Digital Interface)
Section titled “SDI (Serial Digital Interface)”Broadcast standard for uncompressed digital video.
Carries video plus embedded audio (typically 8 or 16 channels).
Available in SD-SDI, HD-SDI, 3G-SDI, 6G-SDI, 12G-SDI variants.
ST 2022 (SMPTE 2022)
Section titled “ST 2022 (SMPTE 2022)”SMPTE standard for IP encapsulation of SDI video.
Transports existing SDI signals over IP networks.
Transitional technology between traditional SDI and native IP (ST 2110).
ST 2110 (SMPTE 2110)
Section titled “ST 2110 (SMPTE 2110)”SMPTE standard for professional media over IP.
Separates video, audio, and metadata into distinct streams.
Enables flexible routing and processing in IP-based broadcast facilities.
Audio networking protocol by Waves Audio.
Transmits multi-channel audio over Ethernet (up to 128 channels per device).
Used in live sound, broadcast, and studio recording applications.
