Summary
Overview
Tieline MPX I & MPX II
Tieline’s MPX I and MPX II codecs deliver composite FM multiplex (MPX) codec solutions for real-time network distribution
of FM-MPX or MicroMPX (µMPX*) signals to transmitter sites. The MPX I is ideal 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.
Both the MPX I and MPX II support sending the full uncompressed FM signal, or compressed µMPX to deliver high-quality
multiplexed FM signals at lower bit-rates. They support analog MPX (BNC) or MPX over AES192 to deliver a wide range of
flexible composite encoder and decoder configurations for many different applications. Order an optional satellite tuner
card at purchase to support decoding DVB-S or DVB-S2 signals.
Features
Features
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 space requirements, as well as site visits for service and support. 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^.
Compressed μMPX and uncompressed FM-MPX encoding and decoding with FM return monitoring
- Single or Dual MPX Composite Encode or Decode: Encode/Decode up to two point-to-point MPX/μMPX composite signals.
- MPX/μMPX Composite Encode or Decode with Encoder or Decoder FM Monitoring: Encode/Decode two point-to-point MPX/μMPX composite signals; at the encoder monitor the demodulated local MPX input or the return feed. At the decoder monitor the MPX output or the secondary MPX feed, which is either the local MPX input or the secondary stream.
