9、 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 respective organization to deal with particu
10、lar 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 information technology, ISO and IEC have establi
11、shed 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 International Standards adopted by the joint technica
12、l 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 may be the subject of patent rights. ISO and I
13、EC shall not be held responsible for identifying any or all such patent rights. Amendment 29 to ISO/IEC 14496-5:2001 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information. This Amendment in
14、troduces Reference Software for LASeR PMSI Tools. This Amendment deals with the reference software of ISO/IEC 14496-20:2008/Amd.3.

18、09/Amd.3 (LASeR PMSI: Presentation and Modification of Structured Information). The LASeR AMD3 Reference software is attached to this Part of ISO/IEC 14496. The reference software consists of the following tools: LASeR decoder, which is to generate LASeR XML files from LASeR binary stream. LASeR fil
19、e parser, which is to manage the scene tree and events from LASeR XML files. LASeR renderer, which is to render and play a LASeR scene. The structure of LASeR PMSI reference software is as follows. Figure F.1 Structure of LASeR PMSI Reference Software The LASeR player is linked with two static libra
20、ries such as libLASeR and libbintoxml, and the other dynamic ones such as LASeRDecoder, XML2SceneTree, SceneTreeParser and Render as shown in Figure F.1. By using these libraries, the LASeR player produces SceneTree from different file types such as xml, lsr files, and then, converts the SceneTree i
21、nto a LASeR SceneTree. Finally, the player renders the scene according to the LASeR SceneTree. F.2 Reference Software The PMSI mechanism provides two distinctive functionalities for Structured Information (SI): presentation and modification. Therefore, the LASeR PMSI Reference Software can access SI
22、 from PI (Presentation Information) by two functionalities as follows: READ: Accessing SI from PI to reuse what is already defined in SI. WRITE: Updating SI from PI to reflect what happens in the scene. Amendment 29:2013 to CAN/CSA-ISO/IEC 14496-5-06ISO/IEC 14496-5:2001/Amd.29:2011(E) ISO/IEC 2011 A

LASeR xmlUpdate event: Informing the update of structured information F.3 Description of how to compile and run the LASeR PMSI Reference Software F.3.1 How to build the code This program has been developed using Microsofts
25、 Visual studio 2008 under Windows XP or above OS. To build the program, 1) Unzip a LASeR_RS_v3.zip file. 2) Double-click on a M3R.sin file in the build VC9 folder 3) Right button click on the LASeRPlayer in the solution explorer 4) Choose the Set as Start Up menu 5) Click on the solution build menu
26、(F7) 6) Copy the files (libcairo-2.dll, libpng12-0.dll, zlib1.dll) in the dll folder 7) Paste the files (libcairo-2.dll, libpng12-0.dll, zlib1.dll) in the bin w32rel folder 8) Copy the files (libDeSAF.dll, libMP4.dll) in the dll VC9 folder Paste the files (libDeSAF.dll, libMP4.dll) in the bin w32rel
