Tieline Introduces New MPX Codecs

They offer composite FM multiplex solutions for network distribution of FM-MPX or µMPX to transmitter sites.

Tieline MPX2 codec, a blue hardware device Tieline will unveil two MPX codecs at the NAB Show next month.

The MPX I and MPX II offer composite FM multiplex codec solutions for real-time network distribution of FM-MPX or MicroMPX (µMPX) signals to transmitter sites, the company said in its announcement.

The manufacturer noted that sending “transmission-ready” FM composite signals allows stations to keep audio processing and RDS gear at the studio, which it says can save money and operating costs. “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.”

It said the MPX I is suitable for transmitting a composite STL signal from a single station with return monitoring, whereas the Tieline 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 applications.

“The MPX I and MPX II support sending the full uncompressed FM signal, or high-quality compressed µMPX at much lower bit rates. An optional satellite tuner card with MPEG-TS and MPE support can receive DVB-S or DVB-S2 signals.”

The announcement was made by VP Sales APAC & EMEA Charlie Gawley. “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,” he said.

Tieline will be in booth C3008.
