This document specifies the framework, concepts, methodology for testing, and criteria to be achieved to claim conformance to multiple parts of the ISO/IEC 21122 series. It lists the conformance testing procedures. This document specifies: — Conformance testing procedures for decoders implementing ISO/IEC 21122-1. — Tests to check which conformance point an ISO/IEC 21122-1 decoder conforms to, that is, whether a decoder satisfies the error bounds required for strict or relaxed conformance. — Conformance testing procedures for decoders implementing ISO/IEC 21122-3. — Tests to check codestreams for conformance to ISO/IEC 21122-1. As such, it provides means to test whether encoder implementations generate syntactically correct codestreams, and whether codestreams generated by such implementations follow the requirements of a particular profile, level and sublevel, and the buffer model implied by them. — Tests to check files for conformance to ISO/IEC 21122-3. — Conformance testing procedures that allow testing whether codestreams conform to any of the profiles specified in ISO/IEC 21122-2. — Conformance testing procedures that allow testing whether codestreams conform to the buffer model specified in ISO/IEC 21122-2 as part of a profile, level and sublevel. — Codestreams, decoded images, and error metrics to be used within the decoder testing procedures. — A buffer model test. — Abstract test suites.
