Testing Policies

HDMI Licensing Administrator, Inc. is the licensing agent responsible for administering the licensing of the HDMI Specification, promoting HDMI technology and providing education on the benefits of the HDMI interface to retailers and consumers.

Prior to mass producing or distributing any Licensed Product or component that claims compliance with the HDMI Specification (or allowing someone else to do such activities), each Adopter must test a representative sample for HDMI compliance. First, the Adopter must self-test as specified in the then-current HDMI Compliance Test Specification. The HDMI Compliance Test Specifications provide a suite of testing procedures, and establishes certain minimum requirements specifying how each HDMI Adopter should test Licensed Products for conformance to the HDMI Specifications. Such compliance testing is limited to evaluation of a product’s compliance with the HDMI Specification and is not designed to test the overall performance of any Licensed Product.

Second, each Adopter must submit the first product of each Licensed Product type (i.e. source, sink, repeater, or cable) to an HDMI Authorized Testing Center (ATC) for testing. Once an Adopter product of each type has passed testing, it is not required to submit to the ATC subsequent products of that type. For example, once an Adopter’s television has passed ATC testing, it is not required to submit another television or other display for ATC testing. However, to help ensure HDMI interoperability, we encourage Adopters to use the ATCs.

The HDMI Compliance Test Specifications represent the minimum compliance testing required for Licensed Products. Successful completion of the Compliance Test Specification or ATC Testing does not guarantee that any product will conform to the High-Definition Multimedia Interfaces, function correctly or interoperate with any other product. Each Adopter is solely responsible for ensuring that its products function correctly, fully comply with the HDMI Specification and Adopter Agreement, and interoperate with other products.
