SUNNYVALE, Calif., December 21, 2010 - MHL, LLC, the entity responsible for administering the MHL Consortium reached another major milestone today with the release of its Compliance Test Specification (CTS), with Simplay™ Labs, LLC, a wholly-owned subsidiary of MHL Promoter, Silicon Image, Inc., as the first Authorized Test Center (ATC). The CTS outlines the testing procedures that MHL™ (Mobile High-Definition Link) Adopters must follow in order to establish that their products satisfy the compliance criteria for the MHL specification. The goal of the CTS is to encourage interoperability and to bring products to market faster with increased performance and greater reliability. The first MHL products are expected to be released in early 2011 and include smartphones, HDTVs, tablets, cables and accessories.

"The release of the MHL CTS and partnership with Simplay Labs are important steps in supporting the broad industry adoption of this new mobile interface," said Tim Wong, president of MHL, LLC. "As MHL technology enters the mainstream, consumers want to be sure the devices they buy will deliver the performance and interoperability they desire everything should work together effortlessly."

MHL at CES
