    • A recording/reproducing apparatus is provided for effecting digital processing to convert an analog video signal into a digital signal without losing character data superimposed over a vertical blanking period of the analog video signal. The recording/reproducing apparatus for converting the analog video signal into the digital signal and recording/reproducing the converted digital signal has a detector which detects character data, which is superimposed over the vertical blanking period of the received analog video signal, at the recording time. A superimposer which encodes the detected character data and superimposes the encoded character data over a digital signal from which the character data was removed, whereby the digital signal with the superimposed character data is recorded on the recording media. There is also a detector which detects first copy guard data superimposed over the vertical blanking period and second copy guard data superimposed over a color burst signal; and an adder which adds the two detected copy guard data to a signal reproduced from the recording media.
    • 提供了一种用于进行数字处理以将模拟视频信号转换为数字信号而不会丢失在模拟视频信号的垂直消隐周期叠加的字符数据的记录/再现装置。 用于将模拟视频信号转换为数字信号并记录/再现转换的数字信号的记录/再现装置具有检测器,该检测器检测在记录时间叠加在所接收的模拟视频信号的垂直消隐周期上的字符数据 。 编码检测到的字符数据并将编码字符数据叠加在去除了字符数据的数字信号上的叠加器,由此具有叠加的字符数据的数字信号被记录在记录介质上。 还有一个检测器,其检测叠加在垂直消隐周期上的第一复制保护数据和叠加在色同步信号上的第二复制保护数据; 以及将两个检测到的复制保护数据添加到从记录介质再现的信号的加法器。
