Este artigo apresenta um modelo orientado a objetos para lidar com o relacionamento temporal de todos os objetos multimídia na plataforma de apresentação. A sincronização dos objetos de mídia compostos é obtida garantindo que todos os objetos apresentados no próximo período "gerenciável" estejam prontos para execução. Para este fim, a natureza das sobreposições é primeiro investigada para vários tipos de objetos. Também são definidas sobreposições críticas que são cruciais na sincronização. O objetivo da sincronização é garantir que os objetos de mídia possam ser iniciados precisamente no ponto crítico da sobreposição crítica correspondente. O conceito de intervalo de apresentação gerenciável é introduzido e o grupo de mídias irredutíveis é definido. O agendamento de recursos de cada grupo de apresentação para tempo de pré-busca de objeto de mídia versus ocupação de buffer também é examinado. Assim, um novo modelo denominado rede de Petri de composição de objetos em cascata de grupos (GCOCPN) é proposto e um algoritmo para implementar este esquema de sincronização temporal é apresentado.

Abstract: This paper presents an object-oriented model to handle the temporal relationship for all of the multimedia objects at the presentation platform. Synchronization of the composite media objects is achieved by ensuring that all objects presented in the upcoming "manageable" period must be ready for execution. To this end, the nature of overlays is first investigated for various types of objects. Critical overlaps which are crucial in synchronization are also defined. The objective of synchronization is to ensure that the media objects can be initiated precisely at the critical point of the corresponding critical overlap. The concept of manageable presentation interval is introduced and the irreducible media group is defined. The resource scheduling of each presentation group for media object pre-fetch time versus buffer occupancy is also examined. Accordingly, a new model called group cascade object composition Petri-net (GCOCPN) is proposed and an algorithm to implement this temporal synchronization scheme is presented.
