1.1 Purpose and Scope This document constitutes the specification of procedures， tools and criteria for testing the compliance of devices with the High-Definition Multimedia Interface Specification Version 1.1. Each individual test is designed to ensure compliance with one or more requirements in the HDMI Specification or in one of its normative （required） specifications. No amount of testing can guarantee 100% interoperability among all passing devices when operated in all possible modes but， properly executed， the tests described in this document should give a very high level of confidence in the ability of the device to interoperate with other HDMI devices. Due to the nature of testing a closed-box system such as a TV or DVD player， there are a variety of requirements in the HDMI Specification which are very difficult or impossible to directly verify. Compliance testing for these items will depend upon alternative methods， which may not have 100% correlation with the HDMI-required behavior but will achieve the objective of generating confidence in the interoperability of the device. Consumer Electronics Control （CEC） test methods are given in the HDMI Compliance Test Specification Supplement 1. Version 1.0 of Supplement 1 will be available shortly. Type B and dual-link functionality is not fully covered by this test specification. Such details will be included in a future version.
