DRM Technology Overview for Digital Radio Engineers

Description

This page explains Digital Radio Mondiale (DRM) as a digital broadcasting standard for radio transmission. It focuses on the technical structure of DRM and its use across AM and VHF/FM bands.

The content outlines how DRM supports audio services, text, and data, and describes the system’s use of COFDM and MPEG audio codecs. It also covers DRM operation below 30 MHz and above 30 MHz, including bandwidth, robustness, and service capacity.

The page presents DRM as an open standard with specifications published by ETSI and recommendations from the ITU. It is primarily a reference resource for broadcasters, engineers, and others involved in digital radio planning and transmission.

The page also links to DRM specifications, field trials, and related technical documents. Its emphasis is on standards, transmission parameters, and implementation details rather than commercial products.
