| Summary: | 碩士 === 臺中師範學院 === 教育測驗統計研究所 === 93 === Personal Computers have already become many people’s essentials for daily life in these years. The incredibly fast development of Internet relatively increases the demands of multimedia applications. In addition, the progress of hardware equipments also pushes the development of multimedia, too. According to multimedia authoring, the methods for creating multimedia content are changing from segment-based authoring to scene-based authoring. Besides, non-interactive multimedia content is not enough for users in recent years. Users are desire to get more interactions with contents. Thus, the interactive content is going to be popular in the future.
Due to the future trend, this study develops a visual authoring system. People can use “drag-and-drop” to create multimedia content easily and quickly. The friendly user interface of this system also reduces the difficulty of setting the scene flows, interactions between users and contents and presenting orders of actors (such as sequence, parallel and so on) in authoring multimedia content.
This study uses MPEG-4 as the output format for the authoring system. Because MPEG-4 is objective and interactive, and it is a formal standard, MPEG-4 can satisfy the needs of this authoring system and can present all features this system has.
Moreover, this MPEG-4 authoring system can cross platforms and support handheld devices. These features may help the multimedia content created from this MPEG-4 authoring system be used widely.
