Online video streaming is one of the most promising applications that is being widely used today. Such streaming videos at high definition (HD) resolution or up consume a large network bandwidth. Current generation video codecs like H.265/High Efficiency Video Coding (HEVC) and VP9 are expected to reduce this bandwidth requirement while providing an excellent viewing quality. ITU-T has developed a standardized parametric opinion model called G.1070 that tries to assess the Quality of Experience (QoE) of any multimedia content. The model outputs an overall multimedia quality Mq which is a combination of the video quality Vq and speech quality Sq. The function Vq has to be validated for different video codecs and formats by carrying out subjective experiments. In this paper we propose for the first time a set of coefficients that enables us to extend the G.1070 opinion model to support the H.265 video codec at full-HD resolution.
