超视频是关注视频内容的超媒体文档。虽然它们长期以来一直使用专门的软件甚至硬件进行部署，但Web现在为它们提供了一个适合标准化语言和实现的基础。然而，超视频设计目前也使用非常特定的模型，仅限于单一类别的文档，或非常通用的超媒体模型，可能无法适当地表达其特定功能。在这篇文章中，我们描述了这些功能，我们介绍了CHM，一个注释驱动和基于组件的模型，通过一个高层次的操作规范概念化超视频。定义了一组可扩展的高级组件，以强调表示和交互功能建模，而较低级别的组件提供更多的灵活性和定制的机会。作为基于注释的，该模型促进了视频内容/元数据及其各种潜在呈现之间的明确分离。我们还描述了WebCHM，CHM与标准的Web技术，提供了一个通用的框架，在Web上进行超视频实验的实现。提供了两个例子，以及一个初步的使用研究的模型及其实施，以验证我们的索赔和建议。
Hypervideos are hypermedia documents that focus on video content. While they have long been deployed using specialized software or even hardware, the Web now offers a ground for them to fit into standardized languages and implementations. However, hypervideo design also currently uses very specific models limited to a single class of documents, or very generic hypermedia models that may not appropriately express their specific features. In this article we describe such features, and we introduce CHM, an annotation-driven and component-based model to conceptualize hypervideos through a high level operational specification. An extensible set of high level components is defined to emphasize the presentation and interaction features modeling, while lower level components offer more flexibility and customization opportunities. Being annotation-based, the model promotes a clear separation between video content/metadata and their various potential presentations. We also describe WebCHM, an implementation of CHM with standard Web technologies that provides a general framework to experiment with hypervideos on the Web. Two examples are provided as well as a preliminary usage study of the model and its implementation to validate our claims and proposals.
