RadioScape extends Software Defined Radio approach to Mobile TV using ADI’s Blackfin Processor



London, UK – 12 March 2007 – RadioScape plc is extending its leadership in
Mobile TV broadcast technology with the addition this year of solutions for Mobile TV
receivers, which will be based on the latest additions to the Blackfin® processor
family from Analog Devices (ADI). Announced today these new, high performance, low power
processors will enable RadioScape to integrate the DAB baseband decoder and the audio
video decoder onto a single platform. This provides a clear saving in costs while being
very competitive on space and power compared to the conventional approach today of having
these on two separate chips.

RadioScape is leveraging its extensive Digital Radio systems knowledge, which comes
from being the only, end-to-end technology provider for DAB, to focus on creating Mobile
TV (MTV) receiver solutions based on the Eureka 147 DAB standard, including the T-DMB and
DAB-IP standards. DAB-based standards have been adopted for MTV in many parts of the
world as they use spectrum that is already available and provide robust reception.
RadioScape’s initial MTV solutions will provide DAB/T-DMB and DAB-IP reception as well as
DAB radio. Its Software Defined Radio (SDR) approach means that it can add additional
standards as appropriate to meet market demands and create multi-standard MTV solutions.

“Using our tightly integrated solution of DAB radio and MTV in mobile phone handsets or
Personal Multimedia Players will enable many features and applications to be created in
software that will further enhance the user experience,” said Les Sabel, RadioScape’s VP
of Technology. “These include music downloads, Electronic Programme Guide, picture
downloads, broadcast websites, interactive voting and games, and other user specified
feeds such as sport, news, traffic, and weather. Our Software Defined Radio approach also
allows service providers to deliver value-added applications to existing customers though
software updates in the field.”

RadioScape’s solution integrates both the Eureka 147-based, baseband decoder software
(including DAB audio, DAB data, T-DMB and DAB-IP) with the Audio and Video decoders (H.264
video and MPEG 4 for both AAC+ and BSAC audio) into a single software solution. “This
approach provides significant cost savings over traditional multiple ASIC designs while
maximising the flexibility of MTV and Digital Radio solutions,” said John Croteau, General
Manager, Convergent Platforms & Services Group, at ADI.

The use of SDR allows MTV and Digital Radio solutions to be quickly tailored to
individual customer and product requirements. This ensures that products can have
differentiating features while also reaching the marketplace in the minimum time. The SDR
approach also allows future proofing for both existing products and new designs. New
product designs can be generated through the addition of a number of multimedia features
(such as pause, rewind, record and cache service) and, in addition, the Blackfin has the
flexibility to be either the system master or a slave coprocessor.

“The ADI investment in technology development and their evolutionary path provides an
excellent route to lower cost, lower power solutions that will have backward compatibility
with previous product generations. This continuity in the development process minimises
the total cost of ownership by improving product development efficiency relative to
traditional approaches where ASIC hardware changes cause significant costly and
time-consuming rework,” added Les Sabel.

RadioScape is now demonstrating this advanced MTV solution to lead customers.
