Resumo


The semantics of current multimedia languages is informal and may lead to the development of ambiguous applications. In this paper we investigate the use of the synchronous language Ceu´ for programming local multimedia applications, in particular, those applications that can be described as a set of synchronized media objects. Ceu´ has a deterministic, concise and accurate semantics which, along with high-level programming constructs, makes the language an attractive alternative for developing multimedia applications. We also present Ceu´ -Media, a library for programming multimedia in Ceu´ . Ceu´ -Media implementation guarantees that the properties of the Ceu´ synchronous semantics are reflected in the multimedia presentation, ensuring inter-media synchronization. We compare the synchronization paradigm of Ceu´ with those of NCL and SMIL, and examine the implementation of representative use cases.
