Abstract
Recent years have witnessed the rapid development of mobile video services. The diversity of mobile devices and video services can result in a difference in a user’s perceptual video quality, which presents a significant challenge for video quality evaluation. An objective assessment model is proposed that considers both video and screen characteristics, where the video characteristics include the video resolution and video coding quality (VCQ), and the screen characteristics include the screen size and screen resolution. By analyzing the relationships between the perceived video quality (PVQ) and the video and screen characteristics, an influential parameter, effective video pixels per inch (EV-PPI), is proposed that combines the two characteristics. Then, the PVQ is estimated with the VCQ and EV-PPI. Experiment results confirm that the proposed method can effectively estimate the user’s PVQ. It can be used as a guideline for both video service providers and mobile device manufacturers to improve the performance of their services and devices.
