Effect of Packet Drop and Jitter on Perceived Video Quality for Various Encoded Video over Streaming Network

Abstract

Transmission of video application over the internet is increasing nowadays. Due to increasing user expectation for high quality multimedia contents, video quality has very important role nowadays. Network characteristics such as packet loss and variation in delayextremely influences the quality of video. Therefore, in this paper, we emulated the effect of packet loss and jitter for different video codec such as H.264 and H.265 to determine the impacts on the received video quality using the objective methods such as PSNR &SSIM. For this, network based emulation was conducted in laboratory using the tools such as OPNET and EvalVid. The result is important in order to understand how above mentioned factors impactthe video quality and also help to choose appropriate delay buffer size and packet repair techniques for various types of video, which will further help to improve the user experience in field of multimedia.
