Silicon Image Expands HDMI™ and Simplay HD™ Testing in China

BEIJING and SUNNYVALE, Calif., July 21, 2006 — Silicon Image, Inc. (Nasdaq: SIMG), a leader in semiconductors for the secure storage, distribution and presentation of high-definition content, today announced the official opening of China’s second High-Definition Multimedia Interface™ (HDMI™) Authorized Testing Center (ATC) in Shanghai, and announced plans to open China’s third HDMI ATC at a location to be determined. These centers will complement existing test centers in Sunnyvale, California and in Shenzen, China. In addition, Silicon Image plans to open additional testing centers in Europe and Taiwan.

Both new HDMI ATCs will be co-located with Simplay HD™ Testing Centers. The Simplay HD™ Testing Program consists of branding, compatibility testing, and education for consumers to provide them with a consistent “plug and play” user experience and to maximize their access to premium high-definition content.

The new testing centers, adding to the existing HDMI and Simplay HD facilities in Shenzhen, will make it easier and faster for Chinese consumer electronics manufacturers to bring HDMI products to market, whether for domestic sale or export. HDMI adoption is growing rapidly in China. There are currently 82 HDMI adopters in China, up from 10 at the start of 2005. More information on the Shanghai testing center may be found at shanghai.hdmi-atc.com.

The expanded testing capability is one of three major announcements made today by Silicon Image, the China Video Industry Association (CVIA) and Silicon Image’s wholly-owned subsidiary, HDMI Licensing, LLC. (Please see the press releases entitled “China Video Industry Association Agrees to Promote and Support HDMI, Will Develop HDMI Technology With Silicon Image” and “HDMI Annual Fee Reduced,” also released today.) As part of their agreement, Silicon Image and CVIA will cooperate in establishing testing and interoperability certification labs in China.

HDMI ATCs test for compliance with the HDMI specification. The Simplay HD Testing Program provides a broader suite of testing services for HDMI products, including enhanced testing of content protection technology and interoperability, as well as testing for compatibility with a suite of other devices that have passed the Simplay HD Testing Program. Products that have demonstrated adherence to the Simplay HD™ Test Specification in testing by Silicon Image’s wholly-owned subsidiary, Simplay Labs, LLC, can be identified with the Simplay HDTM logo and are listed on the Simplay HD website (www.simplayhd.com).

“As Chinese consumer electronics manufacturers rapidly increase their production of HDMI devices, they need convenient access to compatibility testing facilities to ensure the best possible experience for their end users,” said Steve Tirado, president and CEO of Silicon Image. “Our expanded HDMI testing capabilities in China, including the new Simplay HD Testing facility in Shanghai, will help Chinese manufacturers ensure their products are plug-and-play compatible with other high-definition devices worldwide.”
