Silicon Image Opens HDMI Authorized Testing Center

Sunnyvale, California / June 26, 2003 — Silicon Image, (Nasdaq: SIMG), a leader in high-bandwidth semiconductor and system solutions for mass markets, today announced the opening of its Authorized Testing Center (ATC) to provide test services for the High-Definition Multimedia Interface™ (HDMI™). Located at the company's Sunnyvale, Calif. headquarters, the facility is now available for preliminary testing of products submitted by HDMI Adopters. Following completion of the HDMI v 1.0 Compliance Test Specification, the center will provide full testing against the specification.

As mandated by the HDMI Adopter's Agreement and HDMI Compliance Test Specification, Silicon Image's ATC tests for compliance with the HDMI specification to promote compatibility among HDMI devices. A product must pass testing at an ATC before it can bear the HDMI logo or claim conformance to the HDMI Specification.

John LeMoncheck, Silicon Image's vice president of consumer electronics products, stated, "HDMI compliance testing provides a real benefit to manufacturers and consumers alike. Manufacturers benefit because they know their products have passed a rigorous set of tests designed to assist them in verifying HDMI product compliance."

"Consumers benefit because HDMI compliance testing promotes interoperability and helps to assure that the HDMI products in their entertainment system will work together," added, Brett Gaines, president of HDMI Licensing, LLC. "Silicon Image's reputation for standards compliance and its experience as HDMI core technology provider, make them an ideal provider of HDMI compliance testing services."

Myra Moore, president of Digital Tech Consulting, stated, "The proliferation of interface standards is imperative for the success of the next generation of high-definition televisions and the devices consumers will want to connect to those HDTVs. Silicon Image's HDMI program is a step toward delivering those standards," said Moore. "The sooner consumers are offered high-quality HDTV products that they feel confident won't be obsolete in the near future, the faster the HDTV market will take off."

Silicon Image's ATC is equipped to perform all of the testing outlined in the HDMI v 0.9 Compliance Test Specification (announced earlier today), including Transition Minimized Differential Signaling (TMDS™), electrical and physical layer, protocol, audio, video, and EDID testing. The ATC is also capable of performing HDMI cable compliance testing. Typical test durations range from seven to 14 days, depending on product complexity and type. All products submitted to Silicon Image's ATC are tested against the specification's requirements, after which test results are sent to both the manufacturer and HDMI Licensing, LLC.

HDMI Adopters interested in submitting products for testing by Silicon Image's HDMI Authorized Testing Center should contact or their local Silicon Image sales representative for more information.
