    • Disclosed are a signal-separation system using a directional microphone array and a method for providing same. The signal-separation system comprises: a signal-receiving unit which receives a mixture signal, in which a first audio signal and a second audio signal are mixed, using a microphone array comprising: at least one first microphone installed in a first direction, and at least one second microphone installed in a direction different from the first direction, and then receives a reference signal through said at least one second microphone; and an audio-signal separation unit for canceling out the second audio signal in the mixture signal received by the signal-receiving unit. The audio-signal separation unit cancels out the second audio signal using the reference signal input through said at least one second microphone.

    • Disclosed are a periodic payment system for service use fees and a control method thereof, and a service provider of the payment system and a control method thereof. The periodic payment system receiving information on credit of a subscriber from a payment information provider includes a payment acknowledgement server for determining whether or not a demanded payment is acknowledged based on the credit information of the subscriber provided by the payment information provider, and providing payment demand information to the payment information provider if it is determined that the demanded payment is acknowledged. The service provider demands a periodic fixed payment of the payment acknowledgement server irrespective of a payment application date when the subscriber applies for payment for the service use fee, and demands payment of an amount of money excluding an advance payment, which is overpaid on the payment application date, from a periodic fixed fee on a payment update date immediately after the payment application date, of the payment acknowledgement server. The payment acknowledgement server outputs a system error signal if a payment acknowledgement error occurs. Upon receiving the system error signal from the payment acknowledgement server on the payment update date, the service provider informs the subscriber of occurrence of an abnormality of payment acknowledgement. Accordingly, an ill-intentioned early secession of the subscriber from the service can be prevented and the subscriber is informed of an nonpayment due to a system error on a service fee payment date.
    • 公开了用于服务使用费用的周期性支付系统及其控制方法以及支付系统的服务提供商及其控制方法。 从支付信息提供者接收用户信用信息的周期性支付系统包括:支付确认服务器,用于基于由支付信息提供者提供的用户的信用信息确定是否确认所请求的支付,并提供支付需求 如果确定所请求的支付被确认,则向支付信息提供者提供信息。 服务提供者要求定期固定支付付款确认服务器,而不管用户是否申请支付服务使用费用的支付申请日期,并且要求支付不包括在支付上多付的预付款的金额 申请日期,从支付申请日之后的付款更新日期的定期固定费用支付确认服务器。 如果发生支付确认错误,支付确认服务器输出系统错误信号。 在支付更新日期从收款确认服务器接收到系统错误信号时,服务提供商通知订户发生支付确认异常。 因此,可以防止来自服务的用户的意外早期分离,并且由于服务费支付日期的系统错误而向用户通知未付款。
