    • Device and method for correcting a color distortion on a TV receiver, is disclosed, the method including a multi-path channel estimation step wherein a transmission channel existing between a transmitted side in a broadcasting station and a color demodulating circuit in a TV receiver is estimated for obtaining an impulse response using a reference signal transmitted from the broadcasting station for equalizing a multi-path channel, a color subcarrier phase error calculation step wherein a phase error of a color subcarrier between the transmitter side of the broadcasting station and the TV receiver is calculated using the estimated impulse response, and a phase correction of a reproduced color subcarrier step wherein a phase error on the TV receiver in reproduction of a color is corrected as much as the phase error obtained in the color subcarrier phase error calculation step.
    • 公开了一种用于校正TV接收机上的色彩失真的装置和方法,所述方法包括多路径信道估计步骤,其中存在广播站中的发送侧和TV接收机中的彩色解调电路之间的传输信道被估计 用于使用从广播站发送的用于均衡多径信道的参考信号获得脉冲响应;彩色副载波相位误差计算步骤,其中广播台的发射机侧与TV接收机之间的彩色副载波的相位误差为 使用估计的脉冲响应进行计算,以及再现彩色副载波步骤的相位校正,其中,在彩色副载波相位误差计算步骤中获得的相位误差校正与TV再现中的TV接收机上的相位误差相同。

    • A conditional access system (CAS) for processing signals between a pay broadcast management system and a digital receiver includes a resource subscriber management system (RSMS) for predetermining time(s) when to transmit an RCM and/or EMM for checking information on the amount used, informing each receiver of the time(s) via a satellite channel, and transmitting the RCM and/or EMM to each receiver at the predetermined time(s); and a receiver which is automatically turned on at a predetermined time to receive and decode the RCM and/or EMM and then transmit the information on the amount used to the RSMS and automatically turned off after completion of the transmission to the RSMS. Alternatively, the CAS includes: an RSMS for previously informing each receiver of a transmission time(s) for an RCM and/or EMM which are/is non-periodically transmitted at a predetermined time(s) via a satellite channel and transmitting the RCM and/or EMM; and a receiver for storing the informed transmission time information, being automatically turned on if it is a time stored to receive and decode the RCM and/or EMM and transmit information on the amount used to the RSMS, and being automatically turned off after completing the transmission of the information.
    • 用于在付费广播管理系统和数字接收机之间处理信号的条件访问系统(CAS)包括用于预先确定何时发送RCM和/或EMM的时间的资源订户管理系统(RSMS),用于检查关于数量的信息 使用,经由卫星信道通知每个接收机的时间,以及在预定时间向每个接收机发送RCM和/或EMM; 以及接收机,其在预定时间自动接通以接收和解码RCM和/或EMM,然后发送关于用于RSMS的量的信息,并且在完成传输到RSMS之后自动关闭。 或者,CAS包括:用于先前通知每个接收机经由卫星信道在预定时间被非周期性地发送的RCM和/或EMM的传输时间的RSMS,并且发送RCM 和/或EMM; 以及用于存储通知传输时间信息的接收器,如果它是存储的时间被自动接通以接收和解码RCM和/或EMM并且发送关于用于RSMS的数量的信息,并且在完成之后自动关闭 传输信息。
