AUDIOVISUAL SCENE DESCRIPTION I MPEG-4 Moving Picture Expens Group T E P E G ) has established novel approaches for the coding of multimedia content in the international standard MPEG-4. Auditory, visual and other content is subdivided into media objects which together build a 2D or 3D scene. Thus the most efficient coding scheme for each object can be chosen according to its type of media, e.g. video, audio, graphics, etc. [I]. For the combination of the objects MPEG-4 provides a powerful tool-set for scene description, the so-called BIFS (Binary Format for Scene Description) [ 2 ] . Here all the elements describing media objects and their properties are put together as nodes in a scene graph. The resulting structure reflects the mutual dependency of the single objects. This concept is based on the scene graph of the Virtual Reality Modeling Language (VRML) standard [3]. The audio part of this scene description (AudioBIFSj allows to specify the behavior of sound emitting objects in the scene (e.g. their position, level, directivity). These basic fuuctionalities have been extended in version 2 of AudioBIFS where new nodes. mainly for virtual acoustics in a 3D ‘This work was conductcd in the research group IAVAS (Intcmztivu AudioVirual Application Systmmr) which i s funded by lhr Thuringim Minisuy 01 Scicnce.

These are often referred to as Advanced AudioBlFS (AABIFS) and are of main interest for the work described here. In general, the auralization of virtual scenes not only has to reproduce sound sources which are placed in the scenery but also to add ambient sound effects like reverberation. Thus the user can feel the surrounding virtual space by listening to the acoustic cues","PeriodicalId":169376,"journal":{"name":"IEEE International Symposium on Consumer Electronics, 2004","volume":"30 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124616184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
