Doradus Technologies Secures IP Licensing Contract for Its ATSC/QAM Demodulator IP Core With a Major Semiconductor Supplier

SAN JOSE, Calif.--April 21, 2006--Doradus Technologies, Inc., a leader in the design and implementation of advanced modulation technologies for consumer and communication transmission, today announced that it is licensing its VSB/QAM demodulator (DoraVision(TM)) core for digital terrestrial/cable TV integrated receiver applications to a major semiconductor manufacturer. DoraVision(TM) is suitable for any system designed to receive broadcast HD and SD signals including DTV sets, personal computers, DVD recordable devices, set top boxes, tuner modules, and Personal Video Recorders. The core enables system-on-chip (SoC) IC to comply with the FCC tuner mandate; this mandate requires consumer electronics manufacturers to build ATSC digital receivers into all televisions and some digital consumer electronics devices by March 2007.

DoraVision(TM) core meets all of the relevant North American DTV standards and requirements including ATSC A53 and ITU-T J.83 annex B. Designed for minimum power operation, small silicon area and minimal external hardware components, the core is designed to meet and exceed the requirements of ATSC A/74 performance specification guidelines. The core is ideal for semiconductor manufacturers as it is designed for ease of integration in SoC digital picture processing backend or RF tuner front end designs.

"DoraVision(TM) completes the vision of an 8-VSB system that is more robust and smaller in size than the ATSC implementations of today," said Hossein Dehghan, VP of Engineering for Doradus. "Our patent pending equalizer blocks provide the best capture range and acquisition speed in the industry and in fact exceeds stringent test requirements such as Brazil channel ensembles."

"Doradus is committed to producing cores that advance the blending of communications and consumer content distribution both commercially and in the home," explains Sam Heidari, CEO of Doradus. "Through providing IP cores and engineering expertise, Doradus is helping define new standards for converging applications such as digital broadcast, broadband access, and networking technologies to silicon suppliers."

System Evaluation Kits suitable for Digital TV broadcast system design will be available in Q2 of 2006.
