HYBRID NO-REFERENCE VIDEO QUALITY INDICATION FRAMEWORK OVER LTE NETWORKS

This paper proposes an efficient hybrid No-Reference video quality indication framework for the video transmission over LTE networks. Taking the easily obtained PCAP file from any LTE network node as input, we analyze the various header information in the IP packet, extract H264 payload, and save it into H264 Annex B format bitstream, which is further decoded using FFmpeg to get the perceived image. Packet level metrics such as packet loss, packet size, bitstream level metrics such as frame error, frame duration and image level metrics such as blockiness, blur, are obtained using the respective efficient and novel algorithms. Furthermore, the IP packets are mapped to the respective video frame, which enables to see the interplay between network impairment and video quality, troubleshoot the network issue, and eventually improve the end user QoE.
