The client can view the video file by just clicking the file. When the file is clicked that<br />
video file is selected from the database and by using the client’s IP address the file is<br />
transmitted to the client. While transmitting the video file it is divided into two streams<br />
(audio and video) and sent in different ports to reduce the transmission delay and also to<br />
reduce the size of the bandwidth. The divided audio stream and video stream is sent through<br />
RTP protocol. In the receiver side the divided audio stream and video stream is merged to<br />
avoid the mismatching of audio and video and to provide the quality of service (QoS).<br />
5. RESULTS & DISCUSSION<br />
This VoD system consists of two modules namely server and client. When the client<br />
requests a file the whole in<strong>for</strong>mation of the client will be sent to the server. If the server is<br />
refreshed it will display client in<strong>for</strong>mation if any new clients are joined. Then the requested<br />
file is transmitted to the client by clicking transmit button. While transmitting the video file is<br />
divided into audio stream and video stream which decreases the transmission delay at the<br />
startup. In the receiver side these two streams are merged and displayed to client to avoid<br />
audio-video mismatching.<br />
6. CONCLUSION<br />
The architecture of VoD learning system is presented in this paper. Edge Server<br />
architecture is proposed to share the burden of Core Server and it handles the demands<br />
directly. During transmission the video file is divided into audio and video <strong>for</strong>mats to reduce<br />
the transmission delay and to provide QoS. Since the cost of implementing a VoD system can<br />
be reduced observably, it is possible to provide VoD as a commercial service in E-Learning<br />
