Abstract

Because of the limitation of bandwidth and display screen size on the mobile devices, the experience of watching videos on the mobile device is extremely limited, especially in real-time video conferencing. This issue can be solved by the ROI (Region of Interest)-based transcoding. To verify the result of ROI-based transcoding scheme, we need an effective method to assess the ROI-based transcoding video quality. In our system, we used the ITU-T Recommendation G.1070 model to assess the video quality. To use the model, we had to estimate twelve parameters in G.1070 firstly because these parameters used in our system are not in the Annex A of the G.1070. By analyzing the result of the subjective video quality assessment, we estimated the twelve parameters. Based on the twelve parameters, we estimated two weighting factor to assess the ROI-based transcoding video quality.
