Abstract

"APARELHO E MéTODO DE REPRODUçãO DE MEIO DE GRAVAçãO, MEIO DE GRAVAçãO, E, PROGRAMA EXECUTADO POR UM COMPUTADOR". A presente invenção relaciona-se a um aparelho e um método para reproduzir um meio de gravação que requerem entrada de um número de código somente uma vez quando o número de código é requerido ser introduzido a ambos um diretório e uma <39>PlayList<39> para reprodução. Uma pluralidade de diretórios tais como DVR, DVR1, DVRn e similares é formada em um disco. Um diretório DVR tem um indicador <39>DVR_protect_flag<39> colocado nele para controlar reprodução de informação que pertence ao diretório. Também,.rpls em <39>PLAY-LIST<39>, que é um pedaço de informação no diretório DVR, tem um <39>playback_control_flag<39> colocado nele para controlar reprodução dele. Em um caso onde o <39>DVR_protect_flag<39> é 1, a reprodução é permitida somente quando um número de código correto é introduzido. Em um caso onde o <39>DVR_protect-flag<39> e o <39>playback_control_flag<39> são ambos 1, entrada do número de código para o <39>playback_control_flag<39> é omitida quando o número de código correto já foi introduzido para o <39>DVR_protect_flag<39>.
