What: FM Composite Multiplex over IP STL
When: September 20, 2017 6:30 PM
Sponsor: GatesAir, Inc.
Our September SBE meeting topic, Transport Robust and Secure FM Composite Multiplex Signals Over an IP STL, was brought to us by David Agnew of GatesAir.
The emergence of high bandwidth IP network connections is an enabler for the transport of the FM composite multiplex (MPX) signal in a Studio-to-Transmitter Link (STL). David presented use cases to illustrate differences between all analog, all digital, and dual domain FM MPX STLs and the tradeoffs they present with respect to compatibility and network bandwidth, scalability, and delay. They also showed us how this IP based STL can be sent across legacy 950 MHz RF STL channels. Those who attended our February meeting know how this IP based STL can be sent across industrial microwave channels.
