Multimedia presentations are suitable for instruction delivery. In a distance learning environment, multimedia presentations are lecture materials to be broadcasted among a number of workstations connected by networks. In order to manage these course materials efficiently, a multimedia database management system (MDBMS) is essentially important. We propose a MDBMS, which has five layers. Attributes of elements in each layer as well as database operations are discussed. The system supports storage sharing and object reuse. The system is implemented on Windows ’98 with the support from a conventional database management system. Also, we present an instruction-on-demand system, which is an application of the underlying MDBMS. The instruction-on-demand system is used in the realization of several computer science-related courses in our university.

The purpose of this paper is to clarify how students perceive changes in the educational environment, such as distance learning. A survey was conducted by creating questions that were narrowed down into specific methods, such as categorizing remote teaching methods as text-based, on-demand, or interactive, and sub-dividing the on-demand type into slides with sound and on-demand via video recording. As a result, the most common type of class was text-based. The one with the highest level of comprehension was the interactive type, while the on-demand type was found to have the highest level of satisfaction. It was also found that many students believe that Distance learning would continue for some time, with only a minority being willing to take classes in the classroom despite concerns about infection. While many students felt that distance learning was good for them, such as "I don’t need to commute to school" and "I can rewatch videos," some concerns included "I can’t make new friends" and "It’s hard to communicate with others.” Since students who felt lonely with Distance learning fell into two extremes, they were divided into a high loneliness group and a low loneliness group for comparison. As a result, it was found that students with high loneliness did not enjoy Distance learning and were unable to make new friends, while students with low loneliness seemed to enjoy Distance learning and were able to make new friends even when online.

Following the rapidly growing technology, TV started to switch-off from the analogue world to the modern digital technologies of broadcasting. Digital technology has the potential to offer the audience a variety of services apart from the common audiovisual stream. Many of the new services are inherited from the Personal Computers (PC) world, including on-demand features, games, transactions, and other interactive options. Television has had a long history of performing an educational function for the mass audience, typically by broadcasting culturally-relevant movies, documentaries and news, as well as educational programmes. The idea of Distance Learning through a TV blossomed extensively in particular as a complementary educational option besides PC-based e-learning and traditional analogue TV educational programs. In particular, TV-based interactive education promises a huge potential due to its ability to support interactivity while compensating for the low penetration of Internet-enabled computers in comparison with the penetration of a TV in a household.

Lecture-on-Demand (LOD) multimedia presentation technologies among the network are most often used in many communication services. Examples of those applications include video-on-demand, interactive TV and the communication tools on a distance-learning system, and so on. We describe how to present different multimedia objects on a Web-based presentation system. Using characterization of extended media-streaming technologies, we developed a comprehensive system for advanced multimedia content production: support for recording the presentation, retrieving the content, summarizing the presentation, and customizing the presentation. This approach significantly impacts and supports the multimedia presentation authoring processes in terms of methodology and commercial aspects. Using the browser with the Windows Media Services allows those students to view live video of the teacher giving his or her speech, along with synchronized images of presentation slides, and all the annotations/comments. In our experience, this very approach is sufficient to the use of distance learning environment.
