However, (1) semi-automatic content extraction and annotation, (2) scalable indexing model, and (3) effective retrieval and browsing, still pose the most challenging problems for maximizing the usage of large video databases. This paper will present the findings from a comprehensive work that proposes a scalable and extensible sports video retrieval system with two major contributions in the area of sports video indexing and retrieval. First, is an extensible sports video indexing model that utilizes semi-schema-based indexing scheme on top of an Object-Relationship approach to support gradual content-extraction. Second, is a set of novel queries which are based on XQuery to generate dynamic and user-oriented summaries and event structures. The proposed sports video retrieval system has been fully implemented and populated with soccer, tennis, swimming, and diving video. The system has been evaluated against 20 users to demonstrate and confirm its feasibility and benefits. The experimental sports genres were specifically selected to represent the four main categories of sports domain: period-, set-point-, time (race)-, and performance- based sports. Thus, the proposed system should be generic and robust for all types of sports.

Some technologies already allow end-users to watch TV and listen to news podcasts or download music videos on their devices. However, such services are restricted to a provider's selection of preformatted and linear content streams. Hence, we propose a web-based interface system that supports interactive contents navigation, making it possible for end-users to "surf" on video content like they are used to on the Web. This system is extensible to any specific domain of video contents, any webenabled platform, and to any browsing scheme. In this paper, we will explain the architecture and design of this system, propose an application for soccer videos and present the results of its user evaluation.
