This paper presents a flexible and comprehensive framework to conduct objective and Video quality assessment plays a vital role in the field of video subjective evaluations of HAS systems in a fully automated and processing and has gained much attention in recent years. This scalable way. Main features of the proposed approach include paper gives an up⁃to⁃date review of VQA research and highlights end⁃to⁃end evaluation of video streaming players deployed in the challenges to conduct VQA research. Both subjective study industry, collection and analysis of objective streaming performance and common VQA databases, as well as various objective VQA metrics, and subjective quality assessment utilizing crowdsourcing methods are reviewed. The authors pointed out several challenges for QoE evaluation. in VQA, including the impact of video content, the memory effects, the computational efficiency, and the personalized video quality Christian Timmerer and Anatoliy Zabrovskiy prediction.

The authors investigate the significant differences In this paper, the authors point out that conventional video quality between QoS and QoE, summarize the end⁃to⁃end QoE effects in assessment methods have been designed for broadcasting mode of video delivery, and present their classification based on the operations. Emerging Internet⁃based video services are deployment. The authors also specifically analyze the impacts of fundamentally different from broadcasting mode and different different kinds of factors on QoE in video transmission systems. assessment strategies must be adopted. Both subjective and objective metrics should be implemented and the measurement CHEN Jinling, XU Yiwen, LIU Yisang, HUANG Huiwen, and may be carried out at client side, server side and in⁃network to ZHUANG Zhongwen ensure an overall picture of the video service quality.

CONTENTS ZTE COMMUNICATIONS March 2019 Vol. 17 No. 1 (Issue 65) Visual Attention Modeling in Compressed 31 48 Quality⁃of⁃Experience in Human⁃in⁃the⁃Loop Domain: From Image Saliency Detection to Haptic Communications Video Saliency Detection With the worldwide rapid development of 5G networks, haptic This paper explores visual attention modeling in the compressed communications, a key use case of the 5G, has attracted increasing domain for both image and video saliency detection. Saliency attentions nowadays. Its human⁃in⁃the⁃loop nature makes QoE the regions in compressed image or video play a significant role in the leading performance indicator of the system design. A vast number perception of compressed image and video and therefore are of high quality works were published on user⁃level, application⁃level closely related to the quality of experience when viewing the and network⁃level QoE⁃oriented designs in haptic communications. received image and video. In particular, this paper introduces In this paper, the authors present an overview of the recent research fusion strategies to combine spatial and temporal saliency maps to activities in this progressive research area. obtain the consistent result for video saliency map.

In this paper, the authors address the quality assessment of one emerging type of media, omnidirectional In this paper, the authors introduce the development of railway images and videos. They first build an omnidirectional image mobile communications and LTE technology. They also discuss the quality assessment database, and then conduct a subjective quality user requirements of future railway mobile communication system. evaluation study in the VR environment based on this database. The two feasible broadband trunking communication solutions for Some insightful observations have been obtained through this LTE based Next⁃Generation Railway Mobile Communication System interesting study. are then analyzed from different aspects.
