ENCO said it worked with Digigram to deploy a software-centric approach to the requirements of routing live streams of audio over IP.

“For the first time, the audio stream contains both the audio payload and embedded automation control for both the source and destination,” ENCO officials said.

An installation at Radio Veritas Asia in the Philippines is the first commercial use of Digigram Visiblu.

ENCO officials calls the application unique. RVA has a number of language services producing programming that share time on multiple shortwave transmitters. The programming is pre-recorded and produced at the studio, stored on a local file server and sent via data line to a distant transmitter site for storage on a local file server there, then played to air.

Any of the language services must be able to go live on the air on any or all of the transmitters in the case of a major news development without interfering with the operation of the rest of the network, ENCO officials said; there is no audio router or dedicated audio lines between the sites.

The ability to automatically route audio from any of the language service workstations to any of the transmitters is accomplished in software. ENCO said the “STL-on-demand” functionality is integrated into the DAD system, without necessitating additional IP codec hardware.

A description of the project and its use of Digigram Visiblu is here.
