in these Committees is open to all with a bona fide interest in their work SMPTE cooperates closely with other standards developing organizations including ISO IEC and ITU SMPTE Engineering Documents are drafted in accordance with the rules given in Part XIII of its Administrative Practices This document was prepared by Technology Committee 10E Introduction This section is entirely informative and does not form an integral part of this document VC 2 is a wavelet based intra frame video compression system aimed at professional applications that provides efficient coding at many resolutions including various flavors of CIF SDTV and HDTV The VC 2 standard defines a bit stream syntax and a reference decoder specification To aid the creation of new VC 2 streams this recommended practice also provides details for the operation of a sample VC 2 stream generator This recommended practice includes a list of VC 2 compliant streams that can be used to test various aspects of VC 2 decoder compliance This recommended practice also includes a reference decoder for comparisontesting of decoder implementations The reference decoder may also be used to establish the compliance of arbitrary streams Page 2 of 31 Pages 1 Scope The VC 2 video compression standard is an intra frame video compression system defined through the VC 2 stream syntax entropy coding a coefficient unpacking process and a picture decoding process The decoder operations are defined by means of a mixture of pseudo code and mathematical operations This recommended practice defines the materials procedures and criteria for verifying conformance of SMPTE VC 2 video decoders The documents that form this specification include this document a register of test streams a sample VC 2 stream generator and a reference decoder The reference decoder and the sample stream generator are both software written in the C programming language and capable of being compiled to executable code on a variety of computer platforms The reference decoder can be used to verify conformance of VC 2 decoder implementations against a register of test streams and the conformance of arbitrary streams to the VC 2 specification This conformance practice defines both the format for the register of test streams and the lists of test streams 2 Conformance Notation Normative text is text that describes elements of the design that are indispensable or contains the conformance language keywords shall should or may Informative text is text that is potentially helpful to the user but not indispensable and can be removed changed or added editorially without affecting interoperability Informative text does not contain any conformance keywords All text in this document is by default normative except the Introduction any section explicitly labelled as Informative or individual paragraphs that start with Note The keywords shall and shall not indicate requirements strictly to be followed in order to conform to the document and from which no deviation is permitted The keywords should and should not indicate that among several possibilities one is recommended as particularly suitable without mentioning or excluding others or that a certain course of action is preferred but not necessarily required or that in the negative form a certain possibility or course of action is deprecated but not prohibited The keywords may and need not indicate courses of action permissible within the limits of the document The keyword reserved indicates a provision that is not defined at this time shall not be used and may be defined in the future The keyword forbidden indicates reserved and in addition indicates that the provision will never be defined in the future A conformant implementation according to this document is one that includes all mandatory provisions shall and if implemented all recommended provisions should as described A conformant implementation need not implement optional provisions may and need not implement them as described 3 Normative References Normative references are external documents referenced in normative text that are indispensable to the user Bibliographic references are references made in informative text or are those otherwise not indispensable to the user The following standards contain provisions which through reference in this text constitute provisions of this standard At the time of publication the editions indicated were valid All standards are subject to revision and parties to agreements based on this standard are encouraged to
