Abstract
"APARELHO E PROCESSO PARA GRAVAR UM PRIMEIRO E SEGUNDO SINAL DE INFORMAçãO DIGITAL EM TRILHAS EM UM SUPORTE DE GRAVAçãO". Um aparelho de gravação para gravar um primeiro sinal de informação, compreendendo pacotes de informação e um sinal para reproduzir artifícios compreendendo pacotes de informação compreende um gerador de marcação de tempo para gerar marcações de tempo para os pacotes. O primeiro sinal de informação digital é destinado à reprodução a uma velocidade de suporte de gravação que é igual à velocidade de gravação e o segundo sinal digital é destinado para reprodução a uma velocidade n~ 1~ vezes a velocidade de gravação. O gerador de marcação de tempo compreende um primeiro contador para gerar ciclos subsequentes dos subsequentes primeiros valores de contagem, de modo a suprir marcações de tempo para os citados pacotes do citado primeiro sinal de informação digital e um segundo contados para gerar ciclos subsequentes dos subsequentes segundos valores de contagem, de modo a suprir marcações de tempo para os citados pacotes no citado segundo sinal de informação digital, o citado primeiro contador suprindo os citados primeiros valores de contagem a uma primeira taxa, o citado segundo contador suprindo os citados segundos valores de contagem a uma segunda taxa que é igual à citada primeira taxa dividida por n~ 1~.
