Structured Media for Authoring Multimedia Documents

International Journal of Intelligent Systems, 1998

Multimedia documents are composed of different data types such as video, audio, text andimages. Authoring a multimedia document is a creative exercise. Unlike traditional computersupported collaborative work where documents are composed of static objects, multimedia documentshave temporal, spatial and quality of service (QoS) requirements that must be supportedby any collaborative multimedia platform. In this paper, we show that most requirements(including

This paper describes the TDO model of media, which describes media as they are viewing by multimedia authors and the authoring software they use. This model is the basis of the MSPEC medium specification language, which is used to configure a style sheet system for multimedia authoring systems. The TDO model is compared to two other models drawn from multimedia and intelligent systems research and the possibility of creating a general model of media is discussed. An appendix describes recent extensions to the TDO model.

This paper proposes a multimedia presentation system Harmony which can deal with temporal and active media such as motion video, computer animation, and music sounds. Harmony is based on the notion of a hyperobject which integrates a hypertext system with an object-oriented framework. Each object is considered a node as is usual in hypertext systems, and the relations between objects are represented as links between nodes. Harmony extends the ordinary notion of a link. A link in Harmony consists of three components: objects connected by the link, conditions specifying when the link is navigated, and messages sent to the target object. In addition to such an extension, each object can include internal objects called subobjects which specify parts of an object and can become a source/destination of a link. Furthermore, the notion of a group object is introduced to represent a synchronization of parallel displayed media information. Through these extended notions of a hypertext model, temporal and active media can be easily handled through the description of temporal relations from the media in hypermedia documents. Based on the design of Harmony, we have implemented a prototype multimedia presentation system which deals with text, music, graphics, motion video, and computer animation as objects. Harmony consists of three subsystems: link manager subsystem (Harmony/LM), user interface subsystem (Harmony/UI), and object-oriented database (Harmony/DB), where a commercial objectoriented database was employed as the Harmony/DB. Scenario viewer was developed for displaying the structure of scenario in a tree graph which can reduce a cognitive overhead in a hypermedia document. The whole system was constructed based on C++ language.

In this paper a modular authoring system for interactive videos is introduced. The system enables the author to edit the video and add annotations like images, text, hyperlinks to defined scenes or the whole video. It provides a video cutting tool to define scenes, a scene graph to realize non-linear flow of the video and a HTML editor to create text and link annotations. A project can be exported to a XML formatted file with a specific schema and Flash video format (flv) files, which can be interpreted by the project's player. The system is designed to be used intuitively.

Received: 1 November 2020 Accepted: 16 January 2021 Multimedia authoring is the process of assembling various types of media content such as audio, video, text, images, and animation into a multimedia presentation using tools. Multimedia Authoring Tool is a useful tool that helps authors to create multimedia presentations. Multimedia presentations are very widely used in various fields, such as broadcast digital information delivery, digital visual communication in smart cars, and others. The Multimedia Authoring tool attributes are the factors that determine the quality of a multimedia authoring tool. A multimedia authoring tool needs to have several attributes so that these tools can be used properly. The purpose of this literature review study is to find the advantages of the multimedia authoring tool attribute in each of the existing studies to produce knowledge on how to create a good quality multimedia authoring tool. These attributes are Editing, Services, Performance, and th...

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.

For most users, authoring multimedia documents remains a complex task. One solution to deal with this problem is to provide template-based authoring tools but with the drawback of limited functionality. In this paper we propose a document model dedicated to the creation of authoring tools using templates while keeping rich composition capabilities. It is based on a component oriented approach integrating homogeneously logical, time and spatial structures. Templates are defined as constraints on these structures.
