AVT Audio Video Technologies is highlighting a new digital radio installation in Germany.
“With the installation of NDR’s new DAB+ playout system supplied by AVT, listeners will be able to receive news and weather information from their respective regions via DAB+ with a coverage that was previously only possible via FM,” the manufacturer stated.
Norddeutscher Rundfunk, or NDR, is part of the public broadcast association ARD. It serves Hamburg and Mecklenburg-Western Pomerania, Lower Saxony and Schleswig-Holstein.
“The DAB+ playout, which was previously divided into four regions, was replaced by a completely new redundant DAB+ Ensemble multiplexer system for 16 regions,” AVT stated.
It said the large number of different programs was a project challenge, because each of the 16 regional multiplexes can generate eight to nine independent DAB+ programs.
IP-based playout is done with a Magic DABMUX plus Ensemble Multiplexer with integrated DAB+ encoders licensed by FhG.
“The system’s internal redundant switching ensures seamless switching of the multiplex signal, which is available as EDI and ETI/E1 signal. The audio feed to the multiplexers including the audio monitoring is done via AES67 streams, which are connected to Prodigy audio converters from DirectOut,” the company stated.
“The regionally categorized slideshows are created by the PAD playout system of the company 4=1, Dynamic Label+, traffic announcements and TPEG traffic information is generated by the TIC system of the company GEWI. Linkage sets are triggered directly from CGI’s dira! automation software. The monitoring of the entire system is via EMBER+ with a GUI using Lawo VisTool. As management software, the new browser-based AVT DAB System Manager is used which enables the management of all 32 Ensemble multiplexers.”
