Newglee DRM Emergency Broadcasting Solution

Guaranteed delivery of information when it matters most

DRM: Transmission Advantages Built for Emergency Communication

DRM technology is far more than an upgrade in audio quality. Its unique advantages in emergency scenarios make it core infrastructure for national emergency broadcasting systems:

Long-Range Delivery and Wide Coverage: DRM exploits the long-distance propagation of mediumwave (MW), shortwave (SW) and longwave (LW), delivering signals across regions and even continents. This allows information to be delivered directly from a safe, centralized broadcast center to a vast service area, solving the problem of communication outages during regional disasters or infrastructure failures.
Strong Penetration and Environmental Resilience: DRM broadcasting combines low power consumption with strong penetration. When natural disasters damage terrestrial networks or cut power, DRM signals still penetrate effectively, covering the ’last mile’ of remote mountainous or underdeveloped areas and ensuring reliable reception of emergency information.
Synchronized Multimodal Delivery: The system can carry multiple media formats simultaneously within a single transmission channel, so emergency information can be published in parallel as high-quality audio, data captions and SlideShow images — greatly improving reception efficiency and comprehension.

The Core Mechanism: Guaranteed Delivery in Emergency Broadcasting

Newglee’s solution relies on the critical Emergency Warning Functionality (EWF) of the DRM standard to force the delivery of information to receivers:

Forced Activation and Switching: The DRM Announcement mechanism can, in an emergency, forcibly activate receivers that are asleep or switched off and automatically switch them to a preset emergency channel. This forced wake-up is central to ensuring the highest possible delivery rate for emergency information.
Continuous Reception Assurance: The system supports the Alternative Frequency Switching (AFS) mechanism. When a receiver detects that the current frequency’s signal is deteriorating, it automatically guides the receiver to switch to a higher-quality alternative frequency, ensuring continuous reception of emergency information.
Dynamic Reconfiguration: The DRM system supports dynamic reconfiguration, meaning broadcasters can remotely adjust transmission parameters (such as channel bandwidth and protection mode) as a situation evolves, enhancing signal robustness under extreme channel conditions and ensuring critical data is delivered.

Newglee End-to-End Emergency System Architecture

Key Stages of the Architecture Explained

Emergency Broadcast Adapter (EBA)

Acting as the core bridge, it receives and parses the emergency broadcast messages issued by the emergency broadcasting platform.

DRM Media Encoder (DME)

Receives the DIP packets from the EBA, performs audio/data encoding and multiplexing, executes dynamic reconfiguration and generates the DRM multiplex stream. The NGA-101 natively supports EWF.

DRM Modulation and Transmission System

Receives the multiplex stream, modulates it into a high-quality DRM signal, and achieves wide-area coverage through high-power transmitters.

Professional Emergency Receiver

Equipped with automatic wake-up and full-band reception, for professional monitoring and national-level emergency preparedness.

Building a Resilient Line of Defense for Emergency Broadcasting

In the face of sudden disasters and extreme events, traditional communication systems are easily disabled — yet the rapid delivery of life-saving information is critical. The Newglee DRM Emergency Broadcasting Solution harnesses the long-range, wide-area coverage and strong penetration of mediumwave and shortwave to build a resilient communication network that is not dependent on terrestrial infrastructure.

The core strength of our system is its Emergency Warning Functionality (EWF). This mechanism can forcibly wake receivers in any state and automatically switch them to the emergency channel, ensuring that critical information is delivered precisely, at the highest priority and in multimodal form (audio, text, images) — truly leaving no household uninformed. Partner with us today to deploy this indispensable line of defense for your nation and communities.
