Abstract

Frame selection techniques based on semantic analysis are widely used to provide content-based summaries of video sequences. Video adaptation is also required to enable the consumption of these summaries through an increasing variety of devices and networks. Scalable video coding provides embedded coding of video where video adaptation is very simple and efficient. In this paper, we describe a model where both video summarization and adaptation are integrated within the MPEG-21 DIA framework, along with some use cases.
