Abstract: Functional improvements to mobile terminals have made possible the spread of multimedia information delivery services. Especially for sports, a service that extracts important scenes and reports them to users has become popular. We take the approach that situational changes in a game|s progress can be presented as state transitions, and devise an important scene analysis model based on Result Importance (RI), which represents each situation|s actual importance, and Situation Importance (SI), which shows the degree of a chance at the situation. With our model, significant scenes are extracted dynamically. Experimental results indicate that the proposed method is very promising.
