    • An apparatus for detecting data included in a vertical blanking interval of a radio frequency broadcasting signal which can reduce the possibility of error generation in fetching data, and thus accurately and rapidly receive and process additional information included in the broadcasting signal. The data detecting apparatus includes a clock signal generating section for generating a predetermined fetch clock signal in response to a predetermined master clock signal and reset signal, an enable signal generating section for receiving a line select signal and generating a predetermined enable signal in accordance with the master clock signal and the fetch clock signal, a data delay section for delaying serial data for a predetermined time in accordance with the master clock signal and outputting delayed serial data, and a data conversion section for receiving the delayed serial data from the data delay section and converting the delayed serial data into parallel data in accordance with the fetch clock signal from the clock signal generating section, the enable signal from the enable signal generating section, and the reset signal.
    • 一种用于检测包括在射频广播信号的垂直消隐间隔中的数据的装置,其可以降低在获取数据时产生错误的可能性,从而准确且快速地接收和处理包括在广播信号中的附加信息。 数据检测装置包括:时钟信号产生部分,用于响应于预定的主时钟信号和复位信号产生预定的获取时钟信号;使能信号产生部分,用于接收线路选择信号,并根据该信号产生预定的使能信号 主时钟信号和提取时钟信号,数据延迟部分,用于根据主时钟信号将串行数据延迟预定时间并输出延迟的串行数据;以及数据转换部分,用于从数据延迟部分接收延迟的串行数据 以及根据来自时钟信号产生部分的获取时钟信号,来自使能信号产生部分的使能信号和复位信号,将延迟的串行数据转换成并行数据。
