Berlin, Germany - Philippines-based television network Associated Broadcasting Company (TV5) has installed Jünger Audio’s Level Magic technology to balance the audio transmissions it is sending to various cable operators throughout the country.
TV5’s main facilities and transmitter are located in Quezon City, from where it delivers locally produced news, public affairs and entertainment programs throughout the country. The network is aiming to expand dramatically over the next year to cover more Filipino viewers, not only in the country but also the Filipino communities in the Middle East, United States and Europe.
Although most of TV5’s output goes through terrestrial transmission, the broadcaster also transmits through different cable operators in the country, with several relay stations in different major cities in the archipelago. In order to level out these audio transmissions, TV5’s engineers specified a Jünger Audio C8000 Level Magic system, which was supplied by Conversance Systems Network Solutions Inc., via Jünger Audio Asia. The system incorporates Jünger Audio’s adaptive loudness algorithm. This uses a multi-loop dynamic range control principle where slow changes (AGC), fast changes (transient processing) and look ahead peak limiting are handled simultaneously, thus offering level management with exceptionally high audio quality and without coloration, pumping, breathing, distortion or modulation effects. The C8000 ensemble of frames, I/O interfaces and DSPs can be tailored to suit the different processing requirements of individual broadcasters. In TV5’s case the system incorporates an HD-SDI interface, which is specifically aimed at satellite, IPTV or cable re-broadcasters who are struggling with sync and loudness issues when re-broadcasting incoming signals.
Ed Castillo, Director of Engineering, says, “We have installed it in our Technical Operations Centre, after the playout server and before distribution. It has made a dramatic change to our audio output and its dynamic processing has really impressed our engineers because it gives such a quick response.”
Castillo adds, “Level Magic has made a noticeable difference to our audio quality and we are looking forward to making this equipment part of the ongoing expansion and improvement of our system,” he says.
