Teaming up with the Centre of Excellence for Digital Broadcast, RadioScape has demonstrated the capabilities of fusion, the version 6 of its compact Broadcast System with DAB+ capability, by transmitting in L-Band and Band-III across all halls at IBC 2007 in Germany.

Dubbed as DAB+fusion broadcast system, RadioScape's solution enables broadcasters to transmit over twice the number of audio channels possible when using the MPEG 1-Layer 2 standard currently in use.

RadioScape has transmitted different material across the exhibition area including: MPEG 2 audio, DAB+ audio, T-DMB A/V transmissions, MPEG 5.1 Surround Sound courtesy of Fraunhofer-Gesellschaft, DAB-IP A/V, and data services such as Journal Line, Slide Show and DLS.

"The introduction of DAB+ has been well received by broadcasters across the globe," said Les Sabel, VP of technology, RadioScape. "DAB+ significantly increases the number of audio services compared to DAB, providing more choice for consumers. DAB+fusion delivers broadcasters high functionality and flexibility while also significantly reducing the cost per audio channel."

The end-to-end capabilities provided by the combination of the fusion broadcast system and the complementary DAB+ Field Monitor enable broadcasters to undertake field testing of the DAB+ standard to ascertain coverage area and system performance in preparation for commercial rollout. A wide range of testing is possible including HE AAC v2 audio transmission rate assessment and the determination of transmission performance through extensive metrics (such as BERs, Viterbi and Reed-Solomon FEC, DAB+ Fire Code and audio CRCs). The DAB+ Field Monitor also records both the field strength and GPS coordinates, allowing comprehensive coverage maps to be produced.

RadioScape was involved in the WorldDMB Task Force that defined the updated DAB+ standard published in February.
