Abstract

Content providers have recently started adding a variety of meta data to various video programs; these data provide primitive descriptors of the video contents. Personal digest viewing that uses the meta data is a new application in the digital broadcasting era. To build personal digests, semantic program structures must be constructed and significant scenes must be identified. Digests are currently made manually at content provider sites. This is time-consuming and increases the cost. This paper proposes a way to solve these problems with a rule-based personal digest-making scheme (PDMS) that can automatically and dynamically make personal digests from the meta data. In PDMS, depending on properties of the video program contents and viewer preferences, high-level semantic program structures can be constructed from the added primitive meta data and significant scenes can be extracted. The paper illustrates a formal PDMS model. It also presents detailed evaluation results of PDMS using the contents of a professional baseball game TV program.
