Abstract

"MéTODO E APARELHO PARA A DECODIFICAçãO DE UMA SEQüêNCIA DE DADOS EM SISTEMAS DE SEQüENCIAMENTO DE VìDEO áUDIO". Um método para decodificação de uma seqüência de dados contendo subseqüências de áudio/vídeo (14) e controlar subseqüências compreende o armazenamento de nós (12) possuindo a possibilidade de armazenar múltiplos pacotes de dados no mesmo armazenador. Isso pode ser alcançado tendo-se parâmetros separados para o tamanho de armazenamento alocado e qualquer pacote armazenado. Dessa forma, não apenas múltiplos pacotes podem ser armazenados no nó de armazenamento (12), mas também tal nó pode existir enquanto seu armazenador está vazio, de forma que o nó possa ser reutilizado posteriormente. Isso é particularmente útil para o armazenamento e acesso seletivo de múltiplos pacotes de áudio nos nós de áudio MPEG-4 ou nós de som.
