17、2017(E) Introduction This document specifies the conformance and reference software for the ISO/IEC 23005 series. The conformance and reference software serves three main purposes: validation of the written specification of the several parts of ISO/IEC 23005; clarification of the written specificati
18、on of the several parts of ISO/IEC 23005; conformance testing for checking interoperability for the various applications against the reference software which aims to be compliant with ISO/IEC 23005. ISO/IEC 2017 All rights reserved v Information technology Media context and control Part 7: Conforman
19、ce and reference software 1 Scope This document specifies the conformance and reference software implementing the normative clauses of all parts of ISO/IEC 23005. The information provided is applicable for determining the reference software modules available for the parts of ISO/IEC 23005, understan
20、ding the functionality of the available reference software modules, and utilizing the available reference software modules. The available reference software modules are specified in the form of application programming interfaces (API) according to ISO/IEC 23006-1. Furthermore, this document provides
21、 means for conformance testing, i.e. bit-streams (XML descriptions) that conform or do not conform to the normative clauses of the other parts of ISO/IEC 23005 and informative descriptions thereof. 2 Normative references The following documents are referred to in text in such a way that some or all
