This paper presents the concept and implementation of an automated authoring system, to integrate two different modules e-Meeting and e-Learning of the WebELS platform. The primary function of the proposed system is to synchronize the lecturer video stream with the presentation slides in a real-time processing. The system automatically detects the events of slide changing and cursor positions and...
This paper presents an authoring tool for video-based learning content in the WebELS system to support higher education. The primary function of the authoring tool is to synchronize a video stream with the presentation slide by means of video clip timing. Video and presentation files are needed to be uploaded, and subsequently converted at the server. The system utilizes the video timing position...
ASF is widely used in the distance learning area as a streaming media format. Each ASF file is composed of header object; data object and index. The header object of ASF format is lucubrated in this paper. On the basis of researching result, the solution to ASF format streaming media synchronization is proposed and is realized in the platform of network courseware development. The solution includes...
Nowadays, society makes use of new technologies as they appear. Due to this boom, the use of resources via Web is increasing notably. In of training and education cases, companies such as universities are offering tele-learning platforms to complement and facilitate the learning process. Some of these called e-learning platforms can have explanatory videos as a resource for training. For the codification...
In this paper, a multimedia-support e-learning platform called WebELS (Web-based e-learning system) for non-broadband users is introduced. The system includes three main modules: editor, player and manager. Both asynchronous and synchronous e-learning are supported on this platform. Moreover, some technologies are implemented to make the multimedia contents possible for users without wideband network...
This paper discusses a novel e-learning system based on automatic speech recognition (ASR). Transcriptions from ASR can be used for subtitle generation and synchronization, slide synchronization, outline navigation, and content-based video retrieval. So the system can deal with multi-media resources in e-learning automatically. As the core module in this system, the speech recognition system can reach...
In e-learning area, the content development method is one of the most important research topics. This paper proposes a presentation method of visual contents (a text, a still image) in synchronization with narration (sound content) and a pointer to make the efficiency of the resource allocation of cognitive memory capacity increase, and make the transmitted amount of information maximize, based on...
