Abstract

With the growing popularity of personal digital assistants and smart phones, people have become enthusiastic to watch videos through these mobile devices. However, a crucial challenge is to provide a better user experience for browsing videos on the limited and heterogeneous screen sizes. In this paper, we present a novel approach which allows users to overcome the display constraints by zooming into video frames while browsing. An automatic approach for detecting the focus regions is introduced to minimize the amount of user interaction. In order to improve the quality of output stream, virtual camera control is employed in the system. Preliminary evaluation shows that this approach is an effective way for video browsing on small displays.
