Tieline, a renowned codec company, recently launched its latest product, the MPX II codec.
This new offering is designed to provide advanced solutions for the distribution of FM multiplex (MPX) signals in broadcasting networks. It focuses on transmitting composite FM-MPX or the more compact MicroMPX (µMPX) signals.
Capabilities and Features
The MPX II codec stands out for its ability to handle two separate composite FM-MPX signals, facilitating their transport from the studio directly to transmitter sites while enabling real-time return monitoring. The codec is versatile, supporting analog MPX via BNC connectors, MPX over AES192, and is capable of multipoint signal distribution. This versatility allows it to serve as a comprehensive solution for both encoder and decoder applications in various broadcasting scenarios.
Benefits for Broadcasters
According to Charlie Gawley, VP Sales APAC & EMEA at Tieline, the MPX II codec significantly enhances FM radio broadcasting efficiency. One of its primary benefits is allowing broadcasters to keep baseband audio processing and RDS data insertion centralized in the studio. This leads to a reduction in both capital and operational expenses by minimizing the need for additional equipment at transmitter sites. Furthermore, its support for both analog and digital composite MPX signals enables broadcasters to smoothly transition from analog to digital exciters, thereby optimizing their investment in MPX technology.
Technical Advancements
In addition to transmitting the full uncompressed FM signal, the MPX II codec can also send high-quality compressed µMPX signals at considerably reduced bit-rates. It includes an optional satellite tuner card that supports MPEG-TS and MPE, capable of receiving DVB-S or DVB-S2 signals.
Enhanced Distribution and Redundancy
The MPX II codec facilitates the replication and distribution of composite MPX over IP signals using both multicast and multi-unicast technologies. It incorporates robust redundancy features, including redundant streaming, RIST, FEC, and an automated SD card file failover system, ensuring reliable and uninterrupted broadcasting.
