Abstract

"PROCESSO PARA DECODIFICAR SINAIS DIGITAIS CODIFICADOS REPRESENTATIVOS DE DADOS AUDIOVISUAIS". A presente invenção relaciona-se a um processo para decodificar dados audiovisuais permitindo processar, com base em uma linguagem sintática melhorada, elementos distintos de uma cena como objetos para os quais animações individuais, interações particulares usuários/elementos, e relações específicas entre os citados elementos e as animações definidas e/ou interações podem ser providos, a citada descrição sendo organizada em uma árvore hierárquica compreendendo também conexões transversais providas ambas para embutir objetos bidimensionais e/ou tridimensionais em cada outra, e controlando opcionalmente o encaixe de cenas a partir de vários pontos de vista, enquanto se mantém um controle de todas as ações relacionadas, ambas nos objetos embutidos e/ou cenas e nos originais. Aplicação: melhoramento do padrão MPEG4.
