Abstract

Patente de Invneção:<B>"ESTRUTURA DE DADOS DE SINAL DE IMAGEM, MéTODO DE CODIFICAçãO DE IMAGEM E MéTODO DE DECODIFICAçãO DE IMAGEM"<D>. Uma estrutura de dados de um sinal de imagem inclui um identificador de ciclo de reprodução que indica se o ciclo de exibição de imagem para cada quadro é variável ou não. Quando o identificador de ciclo de exibição indica que o ciclo de exibição é fixo, o dado de ciclo de exibição é inserido em um cabeçalho do dado de imagem codificado, e o dados relativo ao número de quadro é inserido em cada quadro. Por outro lado, quando o identificador de ciclo de exibição indica que o ciclo de exibição é variável, o dado de tempo de exibição é inserido para cada quadro. Portanto, quando da decodificação e da exibição do dado de imagem codificado que tem um ciclo de exibição fixo, o dado de imagem decodificado pode ser exibido por meio de uma estrutura de circuito simples, isto é, baseado no dado de ciclo de exibição e no dado de número de quadro que tem uma quantidade de dados relativamente pequena (número de bits), sem referência ao dado de tempo de exibição que tem uma quantidade de dados relativamente grande para cada quadro. Mais ainda, esta estrutura de dados pode ser aplicada a um sinal de imagem codificado que tem um ciclo de exibição variável.
