RadioScape, a world leader in digital audio and multimedia broadcast and receiver technology, has once again been selected to provide the broadcast technology for another Mobile TV trial. Building on the recent success of DAB-IP trials in the UK and Ireland, which used RadioScape’s technology, the Centre of Excellence for Digital Broadcasting (CoEfDB) has just implemented a similar service on one of its four RadioScape Multiplexes in the Netherlands.
Willem Toerink of CoEfDB said, “RadioScape uses a very stable architecture of Internet Protocol (IP) to control content and internal communication within the multiplex. This has proved to be very reliable and has served us well over the past year on our four RadioScape DAB multiplexes. We are now taking DAB on to its logical next step of delivering Data and Mobile TV reliably to mobile handsets using DAB-IP.”
RadioScape has a long established track record of providing DAB broadcasting systems including the world’s largest commercial DAB installation, which is located in the UK. It is also a leading provider of digital radio test equipment and receiver modules. This maturity, experience, and unique end-to-end systems knowledge is positioning RadioScape as the provider of choice for Mobile TV broadcasts based on the proven technology of DMB (Digital Multimedia Broadcasting) using DAB-IP. RadioScape already has over nine DMB installations in major Chinese conurbations and is providing equipment for various trials around the world. This includes the DMB/DAB-IP Mobile TV trial in the UK that was announced on the 5th of June 2006, for which RadioScape is supplying broadcast systems for T-DMB and DAB-IP as well as an L-band COFDM DAB encoder.
“This Mobile TV solution is based on the well proven Eureka 147, DAB standard with an additional layer of algorithms to ensure robust signal protection and is called DMB (Digital Multimedia Broadcast) or, specifically, DAB-IP (DAB Internet Protocol),” added Phil Smith, RadioScape’s Senior VP of Sales and Operations. “DAB-IP was cited by many leading technology companies such as Microsoft at the 2006 3GSM conference as being a key enabling technology for Mobile TV deployment as it is proven in the field, robust and there are frequencies already available in most countries.”
Flexibility and future-proofing are key to RadioScape’s success
RadioScape’s DMB and DAB products are the solution of choice because of the flexibility of being able to be quickly adapted through software to cope with any changes or enhancements in the DMB specifications as they evolve. For example, the RadioScape Broadcast System can be configured to support both DAB-IP and T-DMB via simple software selectable options. T-DMB is typically configured to provide H.264 QVGA sized pictures at a frame rates from 15 to 30 fps using 192 to 512 kbps and higher bit rates, while the Windows Media format focuses on lower bit rates. These multimedia broadcasts will cover news, financial information, music videos, sports, education, movies and the simulcast of terrestrial TV programmes. Importantly, RadioScape’s T-DMB and DAB-IP receivers can also receive DAB radio services bringing the benefits of digital clarity and a wider range of content than offered by FM broadcasting. Indeed, recent field trials for DAB-IP and DVB-H indicated that audio services were generally used more often than video services.
RadioScape Ltd. is the world’s only developer of end-to-end digital audio broadcasting solutions giving RadioScape unmatched systems knowledge and enabling it to ensure that customers receive the highest levels of quality, robustness and reception at all stages.
Its Digital Radio Broadcast Suite is used extensively throughout the world including the largest DAB installation to date — the UK’s commercial DAB network. This is also being used to roll out Mobile TV services using Digital Multimedia Broadcasting in many countries, particularly in the Asia Pacific region where there are already many installations in China.
RadioScape’s innovative Software Defined Digital Radio(TM) approach has made it a leader in DAB and DMB technology with its DAB receiver modules being extensively used by many of the world’s leading consumer electronics manufacturers. The company has recently begun shipping its first generation of DRM/DAB modules, enabling multi-standard consumer receivers to reach retail this year.
