Fraunhofer Institute for Integrated Circuits

DAB+

Overview

DAB+ is based on the original DAB standard but employs the more efficient audio codec HE-AAC v2. This codec allows audio of a higher quality to be broadcast at lower bit-rates. The increased efficiency brings benefits for Governments and Regulators (including better spectrum efficiency), broadcasters (lower costs per station) and consumers (a wider choice of stations).

DAB+ is designed to provide the same functionality as the original DAB radio services, including traffic announcements and PAD multimedia data.

  • Latest MPEG-4 audio codec delivers exceptional performance efficiency
  • More stations can be broadcast on one multiplex (greater station choice for consumers, more efficient use of radio spectrum, lower transmission costs for digital stations)
  • Compatible with existing scrolling text and multimedia services
  • Robust audio delivery
  • Optimized for live broadcast radio
  • Fast re-tuning response time (low zapping delay)
  • Optional surround broadcasting using MPEG Surround

Availability

For broadcasters and receiver manufacturers, Fraunhofer IIS offers DAB+ encoders and decoders as well as professional broadcast server systems.

HE-AAC v2 encoders and decoders optimized for the DAB+ transport layer are available, including super-framing capability and comprehensive PAD support. Fraunhofer IIS provides these codecs for various PC platforms, a wide range of fixed-point and floating-point DSPs, and embedded processors. All have been successfully tested for compatibility with other DAB+ implementations. These codecs can also be obtained in combination with the highly optimized multi-channel extension MPEG Surround.

  • The Fraunhofer DAB/DMB Content-Server™ is available as the professional broadcast solution with full DAB+ support. The ContentServer for Eureka 147 Digital Audio and Multimedia Broadcasting is an easy-to-use encoder system for the DAB/DMB broadcast chain. It features real-time audio and video encoding in MPEG Audio Layer 2, MPEG-4 HE-AAC v2 (DAB+), MPEG Surround, and MPEG-4 AVC, as well as the generation and insertion of almost any data service in PAD and NPAD, like Journaline, Dynamic Labels, and EPG.
