Abstract

"MODOS DE TRUQUE DE INVERSãO EM VìDEO NãO-PROGRESSIVO USANDO GRUPOS ESPECIAIS DE IMAGENS". A invenção se refere a um método (200) e sistema (100) para realizar um modo de truque de inversão. O método inclui as etapas de receber (212) um sinal de vídeo não-progressivo e codificar (214 ) o sinal de video não-progressivo em pelo menos um grupo de imagens tendo pelo menos uma imagem-fonte de previsão e pelo menos uma imagem-fonte de não-previsão. Todas as imagens-fonte de não previsão são previstas a partir da imagem-fonte de previsão de tal modo que nenhuma imagem-fonte de não-previsão e prevista a partir de uma outra imagem-fonte de não-previsão. O método também inclui a etapa de, em resposta a um comando de modo de truque de avanço, alterar (220) a ordem de exibição do grupo de imagens para permitir que o grupo de imagens seja exibido em uma ordem inversa.
