Abstract

INSERçãO DE MENSAGENS SEI DE GRãO DE FILME PARA UMA SIMULAçãO EXATA EM BITS EM UM SISTEMA DE VIDEO. São providos métodos e um aparelho para a inserção de mensagens de informação SEI de grão de filme para uma simulação exata em bits em um sistema de vídeo. Um método para simular um grão de filme em uma seqúência ordenada inclui as etapas de prover (305> informações suplementares de grão de filme que correspondem a uma pluralidade de imagens intracodificadas, e prover (310) informações suplementares de grão de filme adicionais que correspondem às imagens intercodificadas entre imagens intra-codificadas consecutivas, em ordem de decodificação. As imagens inter-codificadas são selecionados com base na ordem de exibição.
