Silicon Image Agrees to License Advanced Digital TV System-on-a-Chip Intellectual Property From Sunplus

SUNNYVALE, Calif. -- Feb. 6, 2007 -- Silicon Image, Inc. (Nasdaq: SIMG - News), a leader in semiconductors for the secure storage, distribution and presentation of high-definition content, today announced that it signed a cross-licensing agreement with Sunplus Technology Co., Ltd. whereby Silicon Image receives the rights to use and further develop advanced intellectual property (IP), for video processors and digital television (DTV) products to accelerate development of Silicon Image's PinnaClear(TM) HDTV and other consumer product lines.

Under the agreement announced today, Silicon Image will obtain a comprehensive license of certain intellectual property from Taiwan-based Sunplus. Silicon Image will pay Sunplus $40 million upon delivery and completion of certain milestones. This agreement enables Silicon Image to enhance its development of DTV technology and other consumer product offerings. The new agreement augments and continues to build upon a long-standing relationship between Silicon Image and Sunplus under which the two companies have been working on a joint project to co-develop a line of integrated video processors for the fast-growing DTV market.

The Sunplus transaction complements the acquisition of sci-worx GmbH ("sci-worx") announced on Jan. 4, 2007. The approximately 140 engineers that joined Silicon Image in this acquisition will play a central role in DTV technology development for Silicon Image, building upon intellectual property originating from Silicon Image, sci-worx and Sunplus.

By strengthening Silicon Image's portfolio of intellectual property and its engineering workforce, the sci-worx and Sunplus transactions are expected to enhance and accelerate Silicon Image's ability to provide top-tier consumer electronics customers with a full line of integrated circuits, ranging from industry-leading discrete High-Definition Multimedia Interface(TM) (HDMI(TM)) chips, new integrated front-end TV input processors and fully-integrated system-on-a-chip (SoC) DTV products that advance a new architecture for premium HD content access throughout the home and mobile environment.

"This transaction, together with the sci-worx acquisition, represents an important step forward in our video integration and connectivity strategy," said Steve Tirado, president and CEO of Silicon Image. "The IP from Sunplus provides several hundred man-years of proven intellectual property development in the digital television and DVD marketplace. With a larger and stronger engineering workforce drawing on the combined IP of three leaders in digital media technology, we expect to be well positioned for long-term growth through more innovative and integrated products for the consumer electronics market."
