CISE Research Instrumentation: Presentation Languages in Multimedia Databases

CDA-9529503 古尔泰金·奥兹索伊奥卢梅拉尔·厄兹索伊奥卢 凯斯西储大学 多媒体数据库中的表示语言 多媒体呈现是指使用显示器同时呈现文本、视频或静止图像以及使用扬声器同时呈现音频的多媒体数据。 每个演示包含从数据库检索的多媒体段，并且由演示管理器软件构造和播放。这项研究有三个组成部分。 (a)一个原型系统的开发，自动组装演示文稿从多媒体数据库开始的计算机用户。 然后，在不同的应用领域的系统进行修改和评估。一个例子是教育中的课程辅助软件。 (b)一个表示构造语言的中级计算机用户的实现和评估在不同的应用领域。 该语言提供对演示中并发段的数量和内容的控制，并且具有指定演示中的播放时间改变以及多个播放管理器之间的通信和同步的能力。 (c)对于高级用户，演示操作语言的开发和评估。 开发是在具有MPEG捕获和播放能力的多媒体个人计算机和工作站上进行的，这些都是由仪器赠款购置的。开发平台为Windows NT和UNIX。

CDA-9529503 Gultekin Ozsoyoglu Z. Meral Ozsoyoglu Case Western Reserve University Presentation Languages in Multimedia Databases Multimedia presentation refers to the concurrent presentation of multimedia data using monitors for text, video or still images, and speakers for audio. Each presentation contains multimedia segments retrieved from a database, and is constructed and played out by a presentation manager software. This research has three components. (a) A prototype system is developed to automate the assembly of presentations from multimedia databases for beginning computer users. The system is then revised and evaluated in different application domains. One example is a Course-Assistant software in education. (b) A presentation construction language for intermediate computer users is implemented and evaluated in different application domains. The language provides control on the number and contents of concurrent segments in a presentation, and has the ability to specify playout-time changes in a presentation, and communication and synchronization among multiple playout managers. (c) For advanced users, a presentation manipulation language is developed and evaluated. The development is carried out on multimedia personal computers with MPEG capture and playout capabilities and on workstations, acquired by the instrumentation grant. The development platforms are Windows NT and UNIX.
