11、ganization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the
12、respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of info
13、rmation technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft Internati
14、onal Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document ma

The diagnosis is pass or fail. 4.15.2 Terminal conformance 4.15.2.1 Conformance Requirements The terminal shall recover the LASeR access units in the LASeR Decoding Buffer bit-exact as constructed by the LASeR encoder. 4.15.2.2 Measurement Procedure The LASeR Access Units recovered from this
20、 conformance point shall be strictly identical to the Access Units stored in the corresponding LASeR track in the test SAF file. 4.15.2.3 Tolerance There is no tolerance.

22、h of a reference implementation at any time. The procedure to test is to make scene dumps according to the format described in this document at some key points in time. The test material must provide the original LASeR bitstream as well as the scene dumps for the same key points in time. The key poi
23、nts will be determined by the author of the test sequence according to the following criteria: in the case of LASeR Command streams, the scene graph shall be checked after the CTS of each command. in the case of events or scripting, the scene graph shall be checked every TBD ms. The assumption is th

Arithmetic precision shall be tested according to the level definition. 4.15.4 LASeR T
