A standard for control of hardware created by the OCA and ratified by the Audio Engineering Society


Open Control Architecture


A communication protocol is a system of rules that allow two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both.


A proprietary standard from Audinate for transmitting audio and video across Ethernet networks


AVB was initially developed by the Institute of Electrical and Electronics Engineers (IEEE) Audio Video Bridging task group of the IEEE 802.1 standards committee. In November 2012, Audio Video Bridging task group was renamed to Time-Sensitive Networking task group to reflect the expanded scope of its work, which is to “provide the specifications that will allow time-synchronized low latency streaming services through IEEE 802 networks”.[5] Further standardization efforts are ongoing in IEEE 802.1 TSN task group. Milan is a subset of these standards used for live performance audio systems.


CobraNet is a combination of software, hardware, and network protocols designed to deliver uncompressed, multi-channel, low-latency digital audio over a standard Ethernet network. Developed in the 1990s, CobraNet is widely regarded as the first commercially successful audio-over-Ethernet implementation.
