Best of Show: Tieline MPX II Codec

It sends “transmission-ready” FM composite signals

We are featuring the products that won the Radio World Best of Show Award at the recent NAB Show. Winners were chosen by a panel of radio engineers and RW editorial staff for their innovation, feature set, cost efficiency and performance in serving the industry.

At the NAB Show, Tieline unveiled the MPX I and MPX II codecs for real-time network distribution of FM-MPX or MicroMPX (µMPX) signals to transmitter sites.

Sending “transmission-ready” FM composite signals allows you to keep your audio processing and RDS gear at the studio. “Composite MPX over IP signals can be easily replicated and distributed using multicast and multi-unicast technologies and take advantage of rock-solid redundancy features like redundant streaming, RIST, FEC and automated SD card file failover.”

The MPX I is suitable 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.

The products will ship later this year. Both support analog MPX on BNC, MPX over AES192 and multipoint signal distribution, to deliver composite encoder and decoder solutions for various uses.

They support sending the full uncompressed FM signal, or high-quality compressed µMPX at much lower bit rates.
