Adding dynamic visual manipulations to declarative multimedia documents

Abstract

The objective of this work is to define a document model extension that enables complex spatial and temporal interactions within multimedia documents. As an example we describe an authoring interface of a photo sharing system that can be used to capture stories in an open, declarative format. The document model extension defines visual transformations for synchronized navigation driven by dynamic associated content. Due to the open declarative format, the presentation content can be targeted to individuals, while maintaining the underlying data model. The impact of this work is reflected in its recent standardization in the W3C SMIL language. Multimedia players, as Ambulant and the RealPlayer, support the extension described in this paper.

Investigating the Collaborative Process of Subtitles Creation and Sharing for Videos on the Web

“…Na literatura podemos encontrar vários trabalhos com enfoque em problemas inerentes à criação [4][9] e ao compartilhamento maciço de arquivos de legendas em bases de dados on-line [8][18] [19]. No contexto do WebMedia, também é possível listar inúmeros esforços dedicados à anotação de mídia para enriquecimento de conteúdo audiovisual [10][15] [17]. Contudo, pouco se sabe sobre as práticas colaborativas de anotação para enriquecimento de conteúdo audiovisual, em particular, no contexto de legendagem para vídeos de séries de TV e filmes.…”

A social approach to authoring media annotations

“…The use of annotations to associate semantics to documents [18,9,15,19] has also been widely investigated. The integration of annotations to document have considered, for instance, audio [23] or handwritten information [22].…”

“…For instance, Kuijk et al. [23] illustrate the annotation-based authoring of multimedia documents by means of a tool which associates audio annotations to photos, and creating structured documents. A similar document engineering approach for video annotation has been proposed by Goularte et al [14], who show the use of multimodal annotations as metadata for indexing retrieval, semantic processing and content enrichment.…”
