Abstract

As more community colleges have adopted a video conferencing system for tele-education and tele-meetings, this new conference technology enables a convenient collaborative communication between the branch campuses and the mother campus through the so-called BCCA network. However, the insufficient bandwidth of video conferencing may often result in high frequent video disruptions, mosaic pictures, frozen pictures and temporary lack of sound. This research, therefore, attempts to analyze the audio and video bandwidth requirements. We aim to identify the minimum bandwidth that would still allow the video conference system to operate while yielding reasonable audio and video quality. We collect the bandwidth data from the video conferencing system from September 2013 to December 2013, both in per minute and per day values and analyze them using Linear programming and Regression analysis.

利用回归和线性规划优化泰国社区学院VDO会议视频/音频带宽的研究

随着越来越多的社区学院采用视频会议系统进行远程教育和远程会议，这种新的会议技术通过所谓的BCCA网络实现了分校与母校区之间方便的协作通信。然而，视频会议的带宽不足，往往会导致视频中断频率高、画面马赛克、画面冻结、声音暂时缺失等问题。因此，本研究试图分析音频和视频带宽需求。我们的目标是确定在提供合理音视频质量的同时仍能使视频会议系统运行的最小带宽。我们收集了2013年9月至2013年12月视频会议系统的带宽数据，包括每分钟和每天的带宽数据，并使用线性规划和回归分析进行分析。
