AES-X192 defines high-performance low-latency streaming audio-over-IP interoperability.

Today most networked audio technology works on a diversity of proprietary and standard protocols. None of the systems are interoperable and have no common basis in IP. X192 will provide interoperability between different network technology, seamlessly interfacing with other products, other networks. With this interoperability mode between existing protocols and compatible with existing network equipment it will be possible to interface different products. With X192 these products could work and play together.

X192 probably in the near future will meet all criteria and may become the base as the only networking protocol for most products. X192 is sponsored by QSC, LLC, Telos, Axia, etc. X192 will be a Layer 3 network technology and applying existing IP protocols such as IEEE 1588, RTP and DiffServ to the challenge of distributing high channel-count, low-latency, uncompressed digital audio. At the moment working in the IP environment, only limited ways are existing to mix and match different equipment.

X192 is using existing standard protocols and technologies, it will definitely not invent new protocols, it defines how existing protocols can be interoperable, how the many existing protocols can be tied together, to be routable over IP networks.

The AVB standard defining media transport over Ethernet with proper synchronization and preventing networks from becoming overloaded. The X192 interoperability standard will be compatible with AVB and receive performance benefits from the AVB infrastructure. AVB defines two types of transport protocol for media data: IEEE 1722 and IEEE 1733. IEEE 1722 defines the Ethernet-only transport and will be incompatible with X192. IEEE 1733 defines an IP transport based on RTP. This part of AVB will be compatible with X192. The interoperability via X192 for this type of AVB is the major goal of the X192 initiative. With X192 implementations of AVB it will reach beyond Ethernet into wider-area applications.
