iMPX: Networked FM-Stereo Composite Connectivity
Description:
The broadcast infrastructure is all about connectivity. What follows, herein, is a comprehensive explanation of iMPX, an innovative method where the FM-Stereo MPX signal is carried over a data link of 320KB/s or greater, as part of the studio-to-transmitter (STL) link. Employing linear technique, or a newly designed codec – which does not produce audible artifacts, this method maintains precision peak control, and yields a transparent MPX signal for transmission. Final limiting and stereo generation are no longer needed at the transmitter. On account of this, “one to many” multicast transmission options are born, RDS signals are included in the payload, and the main processor can live at the studio but still provide peak control as if based at the transmitter. IP distribution of composite signals becomes a logical extension within the AoIP ecoverse.
