Most studies of smoothing video stream compute the required bit rate of video transmission to satisfy all the transmitted data. In this paper, our proposed online smoothing with tolerable data dropping algorithm can adjust the bit rate as smooth as possible. Several multimedia encoding schemes, such as advanced video coding (AVC), can support partial data(More)
This study explores the effect of user and system characteristics on our proposed web-based classroom response system (CRS) by a longitudinal design. The results of research are expected to understand the important factors of user and system characteristics in the web-based CRS. The proposed system can supply interactive teaching contents, quizzes, and(More)
Different content characteristics and bit rates affecting the perceived quality of video has been verified in this study. We select 93 video sequences encoded/decoded by the Microsoft MPEG-4 software and make use of the Principal Component Analysis(PCA) method to find the principal component for all sequences by motion and texture characteristics. All the(More)
A company could grow up steadily and create different values if it makes use of resource efficiently. In the growing process of the digital content industry, using resources efficiently and investing innovation activities are the essential factors in operation performance, R&D performance, and human performance. We build the research framework based on the(More)
Most algorithms of smoothing schedule compute the required bit rate of video transmission to satisfy all the transmitted data. In this paper, our proposed tolerable data dropping algorithm can adjust transmitting data to fit available bit rate. MPEG-4 with fine grained scalability (FGS) can support partial data dropping to adapt to available bandwidth(More)
Computers have entered into all walks of our life and products made by real-time technology are innumerable. Higher education institutions must see this trend and prepare their gradates to satisfy society's needs. Information Systems curriculum recommended by DPMA 1] is not adequate in this regard. In this paper, we explain our rationale in incorporating(More)
