RESUMO

Multimedia applications are characterized for demanding huge network and computing resources. Because these demands, the current development models always were based on highly specialized and integrated architectures. Thus, they present monolithic structures which limits reuse, as well requiring a lot of efforts to perform changes. This approach limits the development of complex and large scale multimedia applications. There are demand for development models for enabling larger scopes application, supporting scalable, flexible and ease programming applications. In this context this work proposes the conjugated use of Service Oriented Architectures and the MPEG-7 and MPEG-21 standards. It presents how these technologies can allow multimedia applications ease development, minimizing coasts and efforts. Besides, it is also showed how they answer for the raising and multiple demands for new multimedia applications types. This work motivation was to create a solution to support some additional requirements verified during the design of a Video Management Platform. Among the diversified issues treated in this work, it is presented how technologies supporting Service Oriented Architectures are positioned regarding multimedia applications development, and how they together MPEG-7 and MPEG-21 standards are being used to improve the Platform. It is also presented an analysis process for applying the principles of Service Orientation in the multimedia applications development. The aim is generalizing the presented solution to be applied in any multimedia application development. As result from the whole work, it can be verified that, although there are some issues to be covered, the technologies presented represent a complete tool for multimedia applications development.
