"DiBcom offers the world's first digital demodulator chip that features robust DVB-H mobile TV performance with very low power consumption," said Yannick Levy, President and CEO, DiBcom. "Our DIB7000(TM) device and Microtune's new MT2260 DVB-H tuner chip provide complementary technology that can enable support for both U.S. and European mobile broadcast networks."

"While support for mobile digital TV broadcast on handheld devices barely registered on the radar screen a year ago, there is a tremendous amount of momentum building behind the application, and we are forecasting strong consumer uptake when services begin to launch," said Jason Blackwell, CEO and Co-founder of S2 Data Corporation. "The development of open standards such as DVB-H is vital to enable and drive the market for mobile DTV, and emerging RF semiconductor technology will significantly impact the design and performance of future DVB-H devices. Silicon suppliers such as Microtune are rising to the challenge of enabling handset OEMs to balance increased functionality and digital TV performance without compromising on aggressive power consumption and integration requirements."
