Tieline MPX II

Beschreibung

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.

Overview...
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 at a glance...

• SD card backup : SD card backup delivers file failover.
• Dual Ethernet Ports : Dual Gigabit (10/100/1000) RJ-45 LAN ports for IP Streaming / Control
• Dual Internal Power Supplies : Dual Power Supplies to protect you in case one fails
• Multicast & Multi-Unicast* : Multi-unicast μMPX signals to reduce CAPEX and OPEX at the studio and TX sites. Multicast uncompressed MPX or compressed μMPX signals
• Redundant streaming : Redundant streaming with hitless packet switching, RIST and Forward Error Correction (FEC)
• Support for GPIOs : Support for GPIOs in MPX or μMPX modes.
• Full remote control : Full remote control using the HTML5 Toolbox Web-GUI, Cloud Codec Controller, plus comprehensive automated alarms and SNMP monitoring.
• Analog and Digital : Support for both analog and digital MPX signals allows networks to support transmissions using analog transmitters as networks transition to newer all-digital setups over time.
• Monitor demodulated MPX : Monitor demodulated MPX at the encoder or decoder.
• Transport Compressed μMPX : Transport uncompressed MPX or reduce bandwidth requirements by transmitting compressed μMPX Composite signals to sites.
• MPEG-TS over Satellite : An optional satellite tuner card with MPEG-TS and MPE support can receive DVB-S or DVB-S2 signals
• Return FM Monitoring : Monitor demodulated MPX locally, or stream an external signal at the decoder back to the encoder for monitoring.

Applications
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.
