Industry Insider — 100% Radio modernizes with WorldCast • RedTech

WorldCast Systems has posted a user story on its website looking at its work with modernizing a French radio network, 100% Radio.

The intro explains that 100% Radio “operates 16 distinct program feeds across 50 FM frequencies and DAB+ across a number of large cities. As the station grew, it faced mounting challenges around scalability, reliability, and operational efficiency. To maintain its competitive edge and deliver consistent, high-quality audio, 100% Radio needed to modernize its broadcasting infrastructure without increasing complexity.”

Problem: “Expanding the number of programs and frequencies made it increasingly difficult to manage audio processing and distribution with traditional, hardware-heavy methods. Each program typically required dedicated audio processors at multiple locations, multiplying equipment, maintenance, and failure points.”

It added: “This setup posed significant hurdles: higher costs, limited flexibility, and a growing risk of service disruption. Most importantly, it became harder to guarantee consistent audio quality across all transmission sites. 100% Radio needed a more agile and centralized approach — one that could scale effortlessly while simplifying operations.”

The answer: “To meet these needs, 100% Radio adopted a software-defined architecture powered by WorldCast Systems’ virtualized APT IP Codecs and APTmpX technology… This eliminates the need for physical codecs at the studio and allows fast deployment of new program streams to feed their FM network.”

In many cases the MPX fed directly to WorldCast Ecreso AoI series FM transmitters via onboard APT soft codecs. Where the transmitters aren’t Ecreso or older models, WorldCast APT Silver hardware decoders are deployed and proved fully backward-compatible with incumbent equipment (see diagram).

APT SureStream redundancy technology is used throughout the network for signal reliability. WorldCast’s Kybio network manager oversees the whole ecosystem.

100% Radio Technical Director Nicolas Leroux said, “Thanks to WorldCast Systems’ optimized FM broadcast chain — from virtualized APT IP Codecs and APTmpX to Ecreso AiO Series transmitters — we’ve achieved a fully scalable solution with exceptional audio quality and a significantly reduced hardware footprint. Managing our network is now easier than ever.”
