As broadcasting technology advances, traditional analog radio is transitioning to digital. Digital Radio Mondiale (DRM) is an advanced digital broadcasting standard that enhances audio quality, efficiency, and accessibility. This solution offers a complete DRM broadcasting system, covering content creation, transmission, reception, and monitoring.
1. Content Production System
High-quality audio is captured using professional equipment such as condenser microphones and stereo recording devices. Digital Audio Workstations (DAWs) like Pro Tools and Adobe Audition handle editing, mixing, and post-production. The NGA-101 DRM content server encodes and multiplexes audio and multimedia data using MPEG xHE-AAC, ensuring efficient digital transmission.
2. Signal Transmission System
The NGA-201A DRM modulator processes encoded signals using OFDM modulation and advanced digital pre-distortion (DPD) technology to optimize signal quality. The NGA-201F medium-wave transmitter, featuring Direct Digital Synthesis (DDS), ensures high-efficiency and stable signal output for AM/FM broadcasting.
3. Reception System
Home & Personal Use: The NGA-801 DRM receiver supports multi-band reception, Bluetooth playback, and emergency alerts.
In-Vehicle Reception: The NGA-701 car receiver delivers stable DRM reception with Bluetooth, USB, and SD card support.
Public Broadcasting: The NGA-711 outdoor speaker, powered by solar and DC, ensures emergency alerts and wide-area coverage.
4. Monitoring System
The NGA-601A monitoring receiver continuously assesses signal quality, while the NGA-610 platform manages multiple receivers, providing real-time data, historical reports, and automated alerts for optimal broadcasting performance.
