PLANO, Texas & PARIS--(BUSINESS WIRE)--June 1, 2005--Microtune(R), Inc. (Nasdaq:TUNE) and DiBcom today announced that they have teamed to combine their class-leading radio frequency (RF) and digital technologies in a series of reference designs targeted for emerging, and potentially high volume, mobile digital TV markets.

The reference designs, based on the digital video broadcast standard (DVB), will make it faster and easier for equipment manufacturers to incorporate leading-edge RF-to-digital subsystems in advanced car TV, PCTV or pordiv TV consumer products

Microtune, headquartered in Plano, Texas, is the inventor of single-chip tuner technology and a worldwide supplier of patented RF components, including very low-power, high-performance silicon tuners

DiBcom, based in Palaiseau, France, is a developer of digital terrestrial television (DTT) demodulators for mobile and pordiv environments based on the DVB standards.

The tuner and demodulator are critical companion components in the reception, tuning and processing of a RF signal in consumer- and automotive-electronics TV devices

"Our strategic teaming is an extension of the strong relationship that has existed with DiBcom for many years," said James A. Fontaine, President and CEO of Microtune.

"With our complementary RF and digital technologies, we are well positioned to work together to shape the future of mobile TV products, as well as to accelerate the time it takes for manufacturers to bring compelling solutions to market.

Given the history of DiBcom's innovative engineering and its technical leadership in the DTT market, this is an exciting relationship."

"Microtune is recognized for the outstanding performance of its tuners across even the most complex applications - in diversity systems, in multi-tuner implementations and in mobile environments," said Yannick Levy, President and CEO, DiBcom.

"By combining Microtune's proven tuner technology with our best-of-breed signal processing, we are providing platform solutions that enable customers to drive innovation in pordiv and mobile entertainment products."

As one of the first initiatives of the relationship, the companies are developing a first-of-its-kind four-tuner/four-demodulator Reference Design for premium car digital TV.

The highly specialized reference design, based on the Maximum Ratio Combiner (MCR) algorithm, offers a complete RF-to-digital subsystem.

It features four Microtune MT7402 analog/digital tuners and four DiBcom DIB3000MC demodulators, a configuration that enables 4-path diversity or 3-path diversity plus one path for handover processing in a single frequency network.

It handles up to four different antenna input signals and it provides an MPEG output

The Reference Design allows automotive electronics suppliers to develop, design and test digital TV/multimedia systems that deliver outstanding performance, comparable to DVD picture and sound quality, at the highest driving speeds.

The reference design is expected to be available in August, 2005, and is priced at $1950

DiBcom has also introduced an innovative PC/TV reference design, the STK7700, aimed at peripherals manufacturers, which enables TV on a PC through an external thumb-size USB stick ('tuner on a stick').

The design combines a Microtune MicroTuner(TM) MT2060 low-power tuner and a new DiBcom DIB7700 DVB-T/USB chip in a complete tuning/demodulator subsystem.

The reference platform enables developers to bring digital TV to PCs in an external, very small, pordiv USB form factor

"Our plan is to leverage each company's products, experience and expertise to bring customers solutions characterized by greatly improved performance, reliability and ease of implementation," added Yannick
