RADIOSCAPE LEADING THE RACE TO PUT DMB INTO MOBILE PHONES
London, UK – 23 February 2004 – A hot topic at this year’s 3GSM World Congress is the provision of data and video to mobile phones. Although 3G has been positioned as the technology that will bring such services to mobile phones, considerable interest is growing in using broadcast technologies as a more efficient method. The solution to achieving this according to RadioScape, is to use the Eureka 147 DAB digital radio standard to deliver these services via DMB (Digital Multimedia Broadcast).
RadioScape will be demonstrating an end-to-end solution on the WorldDAB booth, H24 in Hall 3, at the 3GSM World Congress. The first part is its popular software-based, Professional Digital Radio Broadcast System that encodes the real-time multimedia content using H264 or Windows Media 9 and transmits it using data rates as low as 40kbps for video. This will be received on Samsung and RadioScape prototype DMB receivers.
The second part is the development of digital radio receivers that are small and low powered for integration into mobile devices such as phones, PDAs, etc. RadioScape will be showing for the first time its new RS250H micromodule that measures just 52 by 37 by 7 mm – very similar in size to a Compact Flash module. This is the world’s first tri-band micromodule that delivers FM, RDS, Band III DAB and L-Band DAB for digital radio reception anywhere in the world.
“DMB is an incredibly robust technology as it was specifically designed for accurate reception of multimedia on the move,” explained Nigel Oakley, VP of Marketing at RadioScape. “There is a tremendous interest around the world, especially in Asia Pacific, in the ability to deliver data and video inexpensively to mobile receiving devices using DMB due to its ability to provide high quality services even in difficult reception conditions. Being based on the widely deployed Eureka 147 standard, means that it can be rapidly implemented and easily supported.”
RadioScape’s software-defined digital radio receiver technology is based on Texas Instruments’ DSPs and can enable many different mobile devices, such as mobile phones, to benefit from DMB technology. “RadioScape has a leadership position from being a prime provider of both broadcast and receiver technologies,” concluded Nigel Oakley. “This gives an intimate, end to end total system knowledge that enables us to create innovative solutions and bring them to market ahead of our competition. RadioScape is uniquely positioned to make broadcast multimedia on the move a practical reality.”
Digital Multimedia Broadcast
DMB transmits video and audio over a Eureka 147 DAB data channel and can handle all types of multimedia content such as Windows Media 9, MPEG-4 or RealVideo9 and includes Reed-Solomon Error Correction, Forney Interleaving, and ASI or USP/IP or File Input. Extra Forward Error Correction further enhances the quality and stability of video transmission, which can be either a stream or a packet data channel, reinforcing DAB’s ability to cope with error prone environments especially in a mobile environment.
