Yoshida's opening paragraphs are misleading and lean too heavily on the Radioscape publicity machine. The reason the first DAB offerings were automotive was simply the bulk and power demand of the first-generation (multi-chip) COFDM demod/decoders: the product was a trunk-mounted shoebox; the reason it didn't take off was that it was an after-market solution at a time (1995) when the only DAB broadcasts were in the UK -- there was no incentive for the international auto manufacturers to fit DAB, and only the most dedicated early adopter would shell out the (then) necessary 700 pounds plus installation. This model was shattered in 2001 when Frontier Silicon, in concert with Imagination Technologies, introduced Chorus, a dedicated DAB SoC solution. It was teamed with an innovative 3-dollar RF front-end from RWT, allowing Frontier to manufacture inexpensive add-on DAB modules integrating all the necessary baseband, control and display interfaces on a small card, which could be sold to all the major radio set manufacturers. This is what made possible the 99-pound "kitchen radio" (the Pure 'Evoke' was the first), and the explosion of sales and interest in DAB over the past three years. The phrase "kitchen radio" is all it takes to explain the demographic -- the UK's DAB network has no shortage of 'youth' programming, just look at the list of stations: http://www.wohnort.demon.co.uk/DAB/uknat.html http://www.wohnort.demon.co.uk/DAB/ukloc.html Radioscape followed on some 18 months later with an RF front end that, remarkably, was almost identical to the RWT one: it used the same MOPLL and IF amp, and the same SAW filter, but instead of the SoC they teamed with TI, performing the channel and source decoding in DSP. They have had some success in following the Frontier marketing model. The second half of the piece is accurate: next-generation modules are now sampling from Frontier, and include the international L-Band (1452-1492 MHz) as well as the UK's Band III (high-band VHF), making them suitable for continental Europe and emerging Eureka-147 markets such as Canada. The inclusion of VHF/FM processing means the DAB module can replace, rather than augment, the conventional analog tuner. And of course at this point the car manufacturers start to become interested, especially as the module now takes up only a small part of the standard automobile radio housing; of course the antenna needs to cover the appropriate bands, but that's not brain surgery: in only a matter of a couple of years DAB will become common equipment in new cars. And with public recognition (largely through familiarity with MP3) that the meagre 128 kbits/s allocated to most UK DAB channels is *not* "CD quality", though good enough in a noisy environment, in-car usage may at last catch up with home use. The US digital radio operators and suppliers may well be right in targeting the automotive market. ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
