Well-known media applications of Chromecast such as YouTube, Viki usually use a time slider on the second screen for video navigation. However, the time slider does not offer easy way to access particular contents. Here we propose an aligned thumbnails-based video browsing system with Chromecast using content-based video browsing approach by automatically detecting scenes. It uses hierarchical sliding interface to browse the playing video on TV easily. Through the experimental results, our proposed system helps search specific contents quickly.
