Personalising Live Sports Video Zooming

摘要

An innovative Internet streaming video player, called ePlayer, oriented to live events, has been researched, developed and evaluated. This supports a personalised zoomable user interface. The main novelty of the system is first that it is designed to optimise the zoomed video quality when viewing live events via adaptation of the streamed video quality across multi-video streams with a differing network quality of service. Second, it also personalises the live video zooming with respect to users' zooming preferences, easing the user interaction needed for the zooming task. The experimental results indicate that the system is not only able to zoom effectively but that it can also maintain the visual quality of the video at the same time. ePlayer is also able to infer a user's zooming preferences via dynamically clustering a user's zooming regions of interest when viewing live sports video content.
