    • A digital television signal for use in a digital television receiver for receiving PSIP data from a broadcast transmitter includes a rating region table which includes rating information for multiple geographical regions and a release time field specifying a release time of the rating information. The release time field may be included in a descriptor within the rating region table or in a table ID extension field included in a header of the rating region table, where the table ID extension field serves to establish uniqueness of the rating region table. The release time may be represented as a number of global positioning system (GPS) seconds since a coordinated universal time (UTC). A controller included in the digital television receiver controls storage of the rating region table based upon determining whether the rating information is determined to be newer than pre-stored rating information.
    • 用于从广播发射机接收PSIP数据的数字电视接收机中使用的数字电视信号包括评级区域表,其包括多个地理区域的评级信息和指定评级信息的释放时间的释放时间字段。 释放时间字段可以被包括在评级区域表内的描述符中或包括在评级区域表的头部中的表ID扩展字段中,其中表ID扩展字段用于建立评级区域表的唯一性。 释放时间可以表示为自协调世界时(UTC)以来的全球定位系统(GPS)秒数。 包括在数字电视接收机中的控制器基于确定评级信息是否比预先存储的评级信息更新来控制评级区域表的存储。

    • The present invention relates to an apparatus for processing digital signals capable of detecting jamming signals and achieving a technique using a circuit which detects whether an interference signal of a band of the received frequency exists or not. The apparatus operates from a CDMA-2000 base station device using the technique of a Digital Radio. The invention establishes the detection of jamming signals regarding a received frequency band, comprising: adding an additional digital signal processor (a received signal strength detecting part) other than a DSP which deals with a specific FA using a Multi-Carrier signal processing method of a digital wireless technique; and establishing a detecting function for jamming signals by using the additional digital signal processor as a SCAN, regarding frequency band. In addition, a RF receiver is used among the conventional jamming signal detecting apparatuses, which adds an AGC (Automatic Gain Control) to a DSP which deals with the processing a digital medium frequency signals; and jamming signal detecting function is maintained more simple and inexpensively. And since it is a frequency SCANNING method, it is possible to identify where the frequency band is occurred when a jamming signal is detected.
    • 本发明涉及一种用于处理能够检测干扰信号并且实现使用检测接收频率的频带的干扰信号是否存在的电路的数字信号的装置。 该装置使用数字无线电技术从CDMA-2000基站设备操作。 本发明建立了关于接收到的频带的干扰信号的检测,包括:使用多载波信号处理方法,添加除处理特定FA之外的DSP以外的附加数字信号处理器(接收信号强度检测部分) 数字无线技术; 并且通过使用附加数字信号处理器作为SCAN来建立关于频带的干扰信号的检测功能。 此外,在传统的干扰信号检测装置中使用RF接收机,其将AGC(自动增益控制)添加到处理数字中频信号的DSP; 并且保持干扰信号检测功能更加简单和低成本。 并且,由于是扫描频率的方法,因此当检测到干扰信号时,能够识别发生频带的位置。
