S-DMB (Satellite Digital Multimedia Broadcasting), the world's first service for mobile TV, was launched in Korea and Japan in 2005. S-DMB is based on the ITU System E standard, operating at 2.6GHz frequency, and adopts the complementary gap-filler system for the coverage of shadow areas such as in-building or underground. The number of S-DMB subscribers in Korea continues to grow and surpassed 500,000 as of March 2006. The main applications for S-DMB are wireless handsets and in-vehicle automotive.

GDM7001

GCT Semiconductor offers the industry's first highly integrated CMOS single-chip mobile TV tuner for handheld devices to combine three key functions into one: the RF tuner, channel decoder and the controller. The ultra-low power GDM7001 is currently in production with a top handset manufacturer in Korea and plays a key role in reducing component cost, lowering power consumption, and minimizing footprint by as much as 50 percent. GDM7001 is specifically optimized to support the Korean S-DMB and Japanese MSB mobile broadcast handsets.

GCT Semiconductor plans to combine its proven RF CMOS expertise with state-of-the-art innovative modem technologies in the future to develop and market single-chip tuners for other mobile TV standards. GDM7001 is currently deployed in satellite DMB phones in Korea and Japan. Portable TV solutions and several in-vehicle applications using GCT Semiconductor's latest innovation are expected to be launched in the market place later this year.
