Commercial radio reaches 12.4 million weekly listeners in Australia
2wcom has designed its new DAB-4c converter especially for broadcasters in the process of navigating DAB switchover. The device allows operators to receive data signals from legacy ETI and EDI multiplexers simultaneously and to convert the signals respectively to the EDI/ETI transmitters in the field.
The 2wcom DAB-4c offers four ETI outputs and four ETI bidirectional interfaces (in/out) to increase the number of ETI outputs if for example ETI mirroring is needed. Moreover, the unit features two Ethernet data interfaces in and out.
An optional satellite tuner enables integration into already existing satellite distribution systems. This, the company says, optimizes coverage and allows users to distribute programs to regions that are still lacking broadband IP.
For synchronization of all sites, the DAB-4c uses PTPv2 or an external 10 MHz signal. An internal recovery from the EDI stream by jitter removal assures an ongoing synchronized transmission in case of failure. For transmission robustness, it adds, the unit “seamlessly” switches between two EDI or ETI sources (PFT Dual Streaming).
The system is fully configurable via web interface or remotely via SNMP trap. The 2wcom DAB-4c is compatible with ETSI EN 300 40, ETSI TS 102 563 V1.1.1., EN 300 799 and ETSI TS 102 693 V1.1.2 standards. It also supports Uni- / Multicast (IGMPv2/v3) as well as UDP/DSP.
In addition, DAB-4c provides real-time statistics and monitoring of main DAB+ parameters. On-air monitoring at transmitter sites is possible by an optional DAB tuner.
