Abstract

"MODO TRUQUE EM QUADROS PREDITOS BIDIRECIONAIS". Um método (200) e sistema (100) para realizar um modo truque em um sinal de vídeo. O método inclui as etapas de receber (210) um comando de modo truque, em resposta ao comando de modo truque, repetir (212) uma imagem no sinal de vídeo para formar um sinal de vídeo de modo truque no qual a imagem contém um indicador de exibição; ajustar (214) o indicador de exibição da imagem sendo repetida a um valor predeterminado; e ajustar (216) os indicadores de exibição de imagens repetidas subseq³entes da imagem sendo repetida a um valor predeterminado. Em uma disposição, o modo truque pode ser um modo truque de congelamento, e a imagem a ser repetida pode ser uma imagem predita bidirecional. Em adição, o indicador de exibição pode ser um campo de referência temporal tendo um valor inteiro.
