분산 컴퓨팅환경에서 하이퍼 프리젠테이션을 위한 통합 동기화 기법 = An Integrated Synchronization Method for a Hyperpresentation in a Distributed Computing Environment

다국어 초록 (Multilingual Abstract)

The concept of a hyperpresentation, as an extension of a hypermedia, is the presentation in which time-varying multimedia presentations are dynamically linked together and a hyperlink's context can be changed over time at any time during a continuous presentation. Problems caused by integrating the hyperpresentation into an existing multimedia system which handles a sequential presentation only are, how to describe the hyperpresentation, how to set up a hyperlink on a continuous media, and how to check the consistency of the synchronized presentations. In this paper, a new synchronization description method for the hyperpresentation and a method for setting a hyper link on a continuous media during a presentation are proposed after having survey of existing methods. The proposed method deals with only the DC value in a stream of a DCT based compressed data for checking a condition of the link. Finally, the method for checking the consistency of mixed presentations before actual play of the hyperpresentation is described. Proposed methods are implemented on MuX(Multimedia IO Server), where a sample scenario is tested.
