Abstract

MODO DE OPERAçãO COM AS FUNCIONALIDADES DE VELOCIDADE USANDO IMAGENS PREDITIVAS BIDIRECIONAIS SIMULADAS A invenção diz respeito a um método (200) ou (300) e sistema (100) para realizar um modo de operação com as funcionalidades de velocidade em um sinal de vídeo que contém uma pluralidade de imagens originais digitalizadas progressivamente. O método (200) inclui as etapas de: repetir seletivamente (214) pelo menos uma das imagens originais de forma a converter o sinal de vídeo em um sinal de vídeo do modo de operação com as funcionalidades de velocidade em resposta a um comando do modo de operação com s funcionalidades de velocidade; e uma etapa de inserir seletivamente (216) pelo menos uma imagem preditiva bidirecional simulada no sinal de vídeo do modo de operação com as funcionalidades de velocidade. Além do mais, o método (300) pode incluir a etapa de monitorar (316) o sinal de vídeo do modo de operação com as funcionalidades de velocidade, de maneira tal que a imagem preditiva bidirecional simulada seja inserida seletivamente, quando a taxa de bits exceder um patamar predeterminado. Certas imagens no sinal de vídeo do modo de operação com as funcionalidades de velocidade podem também ser modificadas (220, 328) de forma a refletir uma ordem de exibição pretendida.
