Content-based video adaptation with user´s preferences

We present an integrated system that has been designed to support automatic semantic extraction of highlights in sports video and automatic video adaptation according to user´s preferences. To analyze the user´s satisfaction, we propose a new performance measure that explicitly takes into account the user´s preferences and considers the number and type of errors produced by the annotation engine and the way in which these errors affect the compressed video quality and bandwidth allocation. We provide experimental results with application to soccer and swimming.
