MPEG-4 기반의 멀티미디어 동기화 모델 = MPEG-4 Based Multimedia Synchronization Model

다국어 초록 (Multilingual Abstract)

This paper describes a multimedia synchronization model based on the MPEG-4 (Moving Picture Expert Group) system, which integrates, manages and transfers multimedia objects such as audio, video, image, etc. BIFS(Binary Format for Scene) assigns the presentation and property of the object, and organizes a scene. The paper illustrates the methods of generating the scene description tree, of defining and adding the temporal relationship nodes to the original BIFS tree structure, and of managing them between objects during the playback of multimedia objects. It includes also the development of a MPEG-4 authoring system that users could define the temporal relationships of themselves, and let multimedia objects play.
