In this paper, we have investigated an interaction between video quality and audio quality in order to develop an objective multimedia quality assessment model of high-quality audio-visual media (high-definition video and multichannel audio) according to ITU-T Recommendation J.148 [3]. For that purpose, we have analyzed the interaction by using the subjective quality assessment test of high-definition video and multi-channel audio. As a result, we have concluded that the following three procedures should be considered for the development of the objective multimedia quality assessment model of high-quality audio-visual media: (1) estimation of Aq and Vq from psychophysical quantity of video and audio media, (2) estimation of Aq(Vq) and Vq(Aq) from Aq and Vq, (3) estimation of MMq from Aq, Vq, Aq(Vq) and Vq(Aq) as compliant contetns.
