Digigram Launches Codec for MPX Over IP

Iqoya X/Link-MPX supports evolving STL applications

Digigram, Iqoya, X/Link, MPX over IP, IP codecs,Digigram introduced the Iqoya X/Link-MPX codec, intended for delivery of an FM MPX composite signal to one or several transmitter sites.

“Currently, most of the studio-to-transmitter links for FM transmissions rely on the transport of the baseband audio signal over IP networks,” the company noted in its release. “This requires the FM composite MPX signal to be generated at each transmitter site with devices such as sound processors and RDS encoders.”

It cited growing demand for the transport of the MPX signal to be generated at the studio, “since it will help reduce the number of required equipment at the transmitter sites, optimize the global power consumption and maintenance costs.”

The Digigram X/Link-MPX supports analog MPX and digital MPX AES192, allowing analog-to-analog, analog-to-digital, digital-to-analog and digital-to-digital distribution of the MPX signal.

Optional µMPX compression is available to reduce the cost of transportation by using inexpensive network links.

Features include Forward Error Correction and redundant dual streaming with time diversity in PCM to ensure reliable transportation of IP streams. The codec uses the same hardware platform as the Iqoya X/Link range, and features internal redundant power supply units.
