Journalism students experience “live” on PXL Radio
PXL University of Applied Sciences and Arts’ new radio station gives journalism students the hands-on training they need for careers in radio broadcasting
Tieline has announced it will unveil two new MPX codecs at the 2023 NAB Show.
The new MPX I and MPX II codecs deliver composite FM multiplex codec solutions for real-time network distribution of FM-MPX or MicroMPX (µMPX) signals to transmitter sites. The company says the MPX I is ideal for transmitting a composite STL signal from a single station with return monitoring, whereas the MPX II can transport two discrete composite FM-MPX signals from the studio to transmitters with return monitoring. Both units support analog MPX on BNC, MPX over AES192, and multipoint signal distribution, to deliver a wide range of flexible composite encoder and decoder solutions for different applications.
The MPX I and MPX II support sending the full uncompressed FM signal or high-quality compressed µMPX at much lower bitrates. An optional satellite tuner card with MPEG-TS and MPE support can receive DVB-S or DVB-S2 signals.
“Tieline is excited to unveil these two new MPX codecs, which leverage our longstanding expertise in audio encoding to flexibly and reliably distribute composite signals to transmitter sites,” said Charlie Gawley, VP of sales for APAC and EMEA. “By supporting both analog and digital composite MPX signals, broadcasters can transition from analog to digital exciters over time and maximize the value of their MPX investment.”
Sending transmission-ready FM composite signals from the studio allows broadcasters to maintain audio processing and RDS data insertion at the studio. This significantly reduces capital and operational costs by eliminating processing equipment from transmitter sites, which reduces on-site power consumption, wiring, and site visits for service and support.
Tieline expects the MPX I and II to ship later this year.
