Fuzzy logic inference system based quality prediction model for HD HEVC video streaming over wireless networks

Checking the quality of video transmitted over a wireless network is critical to improving network performance. In this paper, we evaluate the HEVC/H.265 video coding standard in terms of quantization parameters (QP), video content, and the degradation impact of transmission channels on quality. Additionally, studying Quality of Service (QoS) and Quality of Experience (QoE) will allow us to study multimedia applications in wireless ad hoc networks. This paper presents (1) the performance evaluation of QP value variation for different video contents on HEVC/H265, (2) the investigation of the impact of packet loss and jitter on the QoS of transmission sequences, and (3) the fuzzy logic model proposed to evaluate the performance of transmission sequences. The results show that using different QP values can counteract the effects of packet loss and jitter and improve the received video quality.
