RadioScape has now shipped more than 15 DAB/DMB evaluation systems to Korea.

RadioScape has now shipped more than 15 DAB/DMB evaluation systems to Korea.

These are being used by leading companies and research institutes to allow them to develop and plan digital multimedia broadcast (DMB) networks and receiver products.

The company is currently on stand 652 at KOBA 2004 (the Korean International Broadcast Show until 22nd May, 2004 in Seoul) with its Korean distributor Dizipia.

The two will be demonstrating this equipment along with new products to help the roll out of DMB in Korea, which is currently pioneering the implementation of this technology.

Nick Banks, RadioScape's Digital Broadcasting Infrastructure Product Manager, commented: "These DMB systems are based on the same RadioScape technology that has been used in the UK for the deployment of the world's largest DAB audio and data network involving over 40, fully-redundant, multiplexer systems".

As a key player in the development of digital radio standards, RadioScape is currently undertaking field trials with WorldDAB to determine the required field strength for high performance DMB networks.

It is generally accepted that the tolerable bit error rate for video services is in the order of one in a hundred million.

This is much more demanding than the bit error rate for audio of one in ten thousand as the effects can be masked to a large extent by both the receiver and the ear - unlike video where one erroneous bit can corrupt several frames.

RadioScape has developed a new measurement and analysis methodology to categorise the performance of enhanced data and video services under a multitude of environmental conditions to ensure that the specifications of new data and video services will provide the high performance required by DMB customers.

This is now available in the form of the DMB Field Monitoring Receiver that is being launched at the show.

"RadioScape is an extremely well respected provider of digital radio solutions", said Professor Seo, who is a director of the Centre for Advanced Broadcasting Technology at Yonsei University in Korea.

"RadioScape has a unique position in that it is a leading provider of both infrastructure and broadcast equipment for digital radio giving it end-to-end systems knowledge.

The leading broadcasters in Korea are already using RadioScape's digital radio field monitoring equipment to evaluate reception conditions all over the country prior to rolling out DMB services".

JJ Choi, CTO at Dizipia, added, "RadioScape's DMB 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".
