Digital audio and video are increasingly common as data that are manipulated in computer and communication systems. The use of information retrieval mechanisms (e.g., Mosaic, Gopher) that allow the exchange and display of audio, stills, and video is rapidly becoming a major consumer of network bandwidth and storage. Without filtering mechanisms or hierarchical coding schemes one must process a great deal of data to yield sought information. To support future interactive information delivery services such as entertainment, distance learning, home health care, and telecommuting, there is a need to provide efficient means for locating, accessing, and delivering enormous amounts of video content. The research described in this proposal seeks to enable fast access during browsing and retrieval of this video content. The ``fast access'' is proposed to be achieved by a combination of approaches involving: (1) development of domain-specific information models for video content, (2) development of automated information capture for hierarchical coding and scalable delivery in the audio/video domains, (3) use of video query/interface techniques tailored to the information models, and (4) mapping of information content to developed delivery protocols. Anticipated results are techniques and proof of concept for the proposed fast access. Proposed teaching activities encompass the development of courses to reflect the changing needs of computer engineers and the use, evaluation, and promotion of computer-based instructional tools.

数字音频和视频作为在计算机和通信系统中被操纵的数据越来越普遍。使用允许交换和显示音频、静止图像和视频的信息检索机制（例如Mosaic、Gopher）正迅速成为网络带宽和存储的主要消费者。在没有过滤机制或分层编码方案的情况下，必须处理大量数据才能得到所寻求的信息。为了支持未来的交互式信息传递服务，如娱乐、远程学习、家庭保健和远程办公，需要提供有效的方法来定位、访问和传递大量视频内容。本提案中描述的研究旨在使浏览和检索视频内容时能够快速访问。“快速访问”建议通过以下几种方法的组合来实现：(1)为视频内容开发特定领域的信息模型，(2)为音频/视频领域的分层编码和可扩展交付开发自动信息捕获，(3)使用针对信息模型定制的视频查询/接口技术，以及(4)将信息内容映射到已开发的交付协议。预期的结果是所提议的快速访问的技术和概念证明。建议的教学活动包括课程的发展，以反映计算机工程师不断变化的需求，以及使用、评估和推广基于计算机的教学工具。
