In this project, we propose the use of VoIP application as an video conference instead of using the normal telephone line. This technology facilitates the users in the aspect of cost saving as the conference can be made access to the internet without hav of carrying out this project is to test the performance of the codecs installed in the softphone software based on jitter, mean opinion score (MOS), delay and packet loss. The performance of the codecs is analyzed by using network performance monitoring tool available these day.Based on the result, we suggest the best codecs to be used for the software that can guarantee the best performance for the user. In this project, we propose the use of VoIP application as an alternative for making audio and video conference instead of using the normal telephone line. This technology facilitates the users in the aspect of cost saving as the conference can be made, as long as the users have the access to the internet without having to be charged with any additional charges. The objective of carrying out this project is to test the performance of the codecs installed in the softphone software based on jitter, mean opinion score (MOS), delay and packet loss.

“…4, showing one local "Telecentre", where the teacher and local students stand, and many "Remote Points", where the remote students stays. Telecentre and Remote Points communicate through superior quality (roughly 2 Mbps each point) to provide highquality audio and video, allowing to the teacher perform his/hers classes synchronously keeping the class pedagogical quality [Roesler, 2009] [Roesler, 2010]. The teacher sees each remote point through a 46" television, and each remote point sees the teacher through a 46" television and also the teacher´s presentation, as his/hers computer screen is also transmitted.…”

“…Much research for distance learning systems assumes lectures in this traditional style. In (Roesler et al, 2009), the authors focus on a mechanism for efficient delivery of video and audio from the lecturer to the students. In (Shi et al, 2002), the authors propose a Smart Classroom that offers several user interfaces to facilitate lecturing activity of a teacher in distance learning, delivering proper lecturing information to remote students.…”

Abstract:In this paper, we propose a new distance learning system that can adapt to various styles of learning activity. We assume that the system is used in distance classes with multiple live-streaming videos. Our system has functions to change the screen layout to best suit for the current learning situation for each of the participants in a class. The system also has a function to efficiently monitor the behavior of many students at a time. These functions enable us to adapt various learning activities in distance learning classes. We implemented a prototype of the proposed system and evaluated it in experimental classes. We confirmed that our system improved the activities in the experimental classes.
