Abstract

"APARELHO DE GERAçãO DE FLUXO CONTìNUO, MéTODO DE GERAçãO DE FLUXO CONTìNUO, APARELHO DE CODIFICAçãO, MéTODO DE CODIFICAçãO, MìDIA DE GRAVAçãO E PROGRAMA DA MESMA". A presente invenção refere-se a um aparelho de geração de fluxo contínuo que é um aparelho de geração de fluxo contínuo o qual gera um fluxo contínuo que inclui imagens codificadas e um comando para gerenciar um armazenamento temporário o qual contém uma imagem decodificada, o comando sendo adicionado a uma das imagens codificadas como uma imagem de referência. Este inclui uma unidade de julgamento a qual julga se a imagem codificada à qual o comando é adicionado é pulada ou não no momento do ajuste de avanço/retrocesso, uma unidade de adição a qual adiciona, no caso onde a imagem codificada é julgada ser pulada, informações de repetição que indicam o mesmo conteúdo que o comando para outra imagem codificada que segue, em ordem de decodificação, a imagem codificada julgada ser pulada e que não é pulada no momento do ajuste de avanço/retrocesso, e uma unidade de geração a qual gera o fluxo contínuo que inclui as imagens codificadas, o comando e as informações de repetição.
