The DirectOut EXBOX.RAV interface is now equipped with NMOS.

DirectOut Technologies has expanded the capabilities of its recently released RAVENNA/MADI converter EXBOX.RAV with the addition of NMOS (Networked Media Open Specifications) IS-04 and IS-05 support.

NMOS is a suite of specifications for stream discovery and connection management developed and maintained by the AMWA filling a gap left open by the AES67 and SMPTE ST 2110 standards. IS-04 handles device discovery and registration to support automation in setting up networked systems, while IS-05 covers the connection management between devices to allow creation and removal of flows between senders and receivers on the network.

“We’re seeing a lot of AES67 and ST 2110 projects coming up with requests and requirements for NMOS,” says Claudio Becker-Foss, CTO and CEO of DirectOut. “NMOS is a public specification, which fits well with the open approach of RAVENNA. Based on modern network protocols, it eases the device integration into network management and orchestration software. Being now NMOS ready makes EXBOX.RAV even more attractive as a compact and cost-effective interface for IP infrastructures.”

NMOS is one of the several capabilities offered by EXBOX.RAV, which include FastSRC for sample rate conversion when dealing with different clock domains, and EARS (Enhanced Automatic Redundancy Switching), designed by DirectOut to improve reliability of digital multichannel audio systems. Network redundancy is also granted by compliance with ST 2022-7.

NMOS has also been added to the RAVENNA modules offered for the PRODIGY Series and to DirectOut’s OEM board RAV2.
