Infraestrutura para transmissão de conteúdo multimídia com suporte à adaptação de fluxos.

Abstract

The spread of different kinds of multimedia applications has enabled a powerful interaction between users in diverse locations. However, the best effort service nature of the Internet requires a continuous process of stream adaptation, in order to fetch such differents scenarios of transmission. As a consequence, this additional task should be met in the multimedia application development. On the other hand, according to the great heterogeneity of both transmission resources and terminal requirements, it is impracticable to define a unique adaptation method which be optimal for all scenarios. Therefore, we have an increasing complexity of multimedia application development. This work presents an infrastructure to multimedia application development to support stream adaptation. It provides a flexible way to implement and to use adaptation methods, meeting the requirements of different applications. Within this context, in order to validate the developed work, it was implemented two case studies: how to develop multimedia applications with support of stream adaptation and present the extensibility provided by proposed infrastructure through the dynamic addition of new adaptation methods.
