Abstract
In this paper, we compare three transmission and presentation methods in the same total bitrate for Multi-View Video and Audio (MVV-A) IP transmission in terms of QoE. We use an MVV-A system with four cameras, i.e., the system has four viewpoints. The three transmission and presentation methods are the one-view one-stream method, the one-view four-streams method and the four-views four-streams method. The one-view one-stream method transmits and displays only a viewpoint selected by a user with high bitrate. The one-view four-streams method transmits all the viewpoints with low bitrate and displays only a viewpoint selected by the user. The four-views four-streams method transmits and displays all the viewpoints with low bitrate. QoE is evaluated by subjective experiment with 11 adjective pairs. As a result, under the situation that the user can change the viewpoint quickly, the one-view one-stream method can satisfy the user. On the other hand, under the situation that the user cannot change the viewpoint quickly, the user feels that the usability of the four-views four-streams method is good.
