Abstract

APARELHO DE DECODIFICAçãO DE VìDEO ESCALáVEL, MéTODO DE DECODIFICAçãO DE VìDEO ESCALáVEL, E MìDIA DE GRAVAçãO TENDO GRAVADO NA MESMA UM PROGRAMA PASSìVEL DE LEITURA EM COMPUTADOR Trata-se de um método e um aparelho para codificação escalável provendo escalabilidade em um codificador. O aparelho de codificação de vídeo escalável inclui um seletor de modo que determina uma ordem de filtragem temporal de um quadro e um limite de tempo previamente determinado como condição para determinação de qual é o quadro em que deverá ser realizada filtragem temporal, e um filtro temporal que realiza compensação de movimento e filtragem temporal, de acordo com a ordem de filtragem temporal determinada no seletor de modo, em quadros que atendem a condição descrita acima. De acordo com o método e aparelho, na medida em que é provida escalabilidade no codificador, é possível assegurar uma estabilidade na operação de aplicações de "streaming" de vídeo bidirecional em tempo real, tal como vídeo-conferência.
