Interactive laserdiscs are of limited value in large group learning situations due to the expense of establishing multiple workstations. The authors implemented an alternative to laserdisc video by using indexed digital video combined with an expert system. High-quality video was captured from a laserdisc player and combined with waveform audio into an audio-video-interleave (AVI) file format in the Microsoft Video-for-Windows environment (Microsoft Corp., Seattle, WA). With the use of an expert system, a knowledge-based computer program provided random access to these indexed AVI files. The program can be played on any multimedia computer without the need for laserdiscs. This system offers a high level of interactive video without the overhead and cost of a laserdisc player.
由于建立多个工作站的费用较高,交互式激光视盘在大型团体学习场景中的价值有限。作者通过使用索引数字视频结合专家系统实现了激光视盘视频的替代方案。高质量视频从激光视盘播放器捕获,并与波形音频结合成Microsoft Windows视频环境(微软公司,华盛顿州西雅图)中的音频视频交错(AVI)文件格式。通过使用专家系统,一个基于知识的计算机程序可对这些索引AVI文件进行随机访问。该程序可在任何多媒体计算机上播放,无需激光视盘。该系统提供了高水平的交互式视频,而无需激光视盘播放器的开销和成本。
