Abstract

INICIALIZAçAO DE SEMENTE EXATA EM BITS PARA GERADORES DE NúMEROS PSEUDO-ALEATóRIOS USADOS EM UM SISTEMA DE VìDEO. São providos métodos e aparelhos para a inicialização de sementes exatas em bits para os geradores de número pseudo-aleatório usados em um sistema de video. Um método inclui as etapas de criar (205) uma tabela de pesquisa de sementes de gerador PRNG, e de inicializar (210) uma das sementes de gerador PRNG da tabela de pesquisa para uma imagem por meio do acesso da tabela de pesquisa usando um valor que corresponde a uma ordem da imagem.
