Abstract

Video streaming has become an immensely effective technique to share videos over the internet. It is being widely used for video conferencing, e-learning, TV broadcasting, voice over IP and in different multimedia applications. The user’s quality of experience for watching the video is most important for service providers primarily for providing a smooth users’ experience. However, a number of factors affect video streaming quality such as delay and distortion in the network which affects user’s perception of the quality of received videos. It is essential to ascertain the factors which can minimize the effects of these factors on video quality and ensure an adequate level of video streaming quality.
In this paper, we try to find out the effect of packet duplication and rate control on users’ experience in the simulated videos. We try to evaluate the quality of experience perceived by the users and analyze the results using a mean opinion score obtained from different surveys conducted on users’ experience on video streaming. Our in-depth analysis of users’ experience about video streaming shows that the users’ opinion about a video quality follows a similar trend. From our analysis, we were able to estimate a threshold level 1536kbit/s for bit rate and packet duplication level on 3.5%, which represent satisfactory levels of users’ experience, given the constraints of network bandwidth. Our analysis and proposed solutions for maintaining and adjusting appropriate/affordable settings of bit rate and packet duplication are helpful for the service providers to deliver a smooth user experience
