    Component-based Hypervideo Model: high-level operational specification of hypervideos
    (CERIST, 2011-06) Sadallah, Madjid; Aubert, Olivier; Prié, Yannick
    Hypervideo offers enhanced video-centric experiences with attractive and powerful features. Usually defined from a hypermedia perspective, the lack for a dedicated specification prevents hypervideo domain and concepts from being broadly investigated. This article proposes a formal hyper¬video model beyond conventional and very general ones. Followingtheprinciples of component-based modeling and annotation-driven content abstracting, CHM – the proposed Component-based Hypervideo Model - is a high level rep-resentation of hypervideos that intends to expose a gen¬eral, easy to use, comprehensive, expressive, intuitive and dedicated hypervideo data model. Considered as a video-¬centric interactive document, the CHM hypervideo presen¬tation and interaction features are emphasized throughhigh level document operational specification. Our annotation¬-driven approach promotes a clear separation of data from video content and document visualizations. The model serves as a basis for a Web-oriented implementation that provides a declarative syntax and accompanying tools for hypervideo documents design in a simple yet powerful and Web standards¬ compliant manner.

    Component-based hypervideo model: high-level operational specification of hypervideos
    (ACM New York, NY, USA, 2011) Sadallah, Madjid; Aubert, Olivier; Prié, Yannick
    Hypervideo offers enhanced video-centric experiences. Usually defined from a hypermedia perspective, the lack of a dedicated specification hampers hypervideo domain and concepts from being broadly investigated. This article proposes a specialized hypervideo model that addresses hypervideo specificities. Following the principles of component-based modeling and annotation-driven content abstracting, the Component-based Hypervideo Model (CHM) that we propose is a high level representation of hypervideos that intends to provide a general and dedicated hypervideo data model. Considered as a video-centric interactive document, the CHM hypervideo presentation and interaction features are expressed through a high level operational specification. Our annotation-driven approach promotes a clear separation of data from video content and document visualizations. The model serves as a basis for a Web-oriented implementation that provides a declarative syntax and accompanying tools for hypervideo document design in a Web standards-compliant manner.

    Hypervideo and Annotations on the Web
    (IEEE Computer Society Washington, DC, USA, 2011-09-08) Sadallah, Madjid; Aubert, Olivier; Prié, Yannick
    Effective video-based Web information system deployment is still challenging, while the recent widespread of multimedia further raises the demand for new online audiovisual document edition and presentation alternatives. Hyper video, a specialization of hypermedia focusing on video, can be used on the Web to provide a basis for video-centric documents and to allow more elaborated practices of online video. In this paper, we propose an annotation-driven model to conceptualize hyper videos, promoting a clear separation between video content/metadata and their various potential presentations. Using the proposed model, features of hyper video are grafted to wider video-based Web documents in a Web standards-compliant manner. The annotation-driven hyper video model and its implementation offer a general framework to experiment with new interaction modalities for video-based knowledge communication on the Web.
