摘要： A magnetic recording and reproducing apparatus includes an input circuit (2, 9) for inputting the digital signal, an identification information addition circuit (16, 27) for adding recording identification information indicative of recording identification for the digital signal input through the input circuit, a recording circuit (17) for recoding the digital signal with the recording identification information on the recoding medium, a reproducing circuit (20, 21) for reproducing the content of the recording medium, an identification information detecting portion (22) for detecting the identification information from a reproduced signal (91) reproduced by the reproducing circuit for ouputting an identification information detection signal (114) indicative of detection of the identification information, a storage circuit (23) for storing the reproduced signal, a time stamp detection circuit (82) for detecting the time stamp from the reproduced signal stored in the storage circuit, an output control circuit (26) for generating a timing for reading the reproduced signal from the storage circuit on the basis of the time stamp detected by the time stamp detection circuit, a reset circuit (27) for resetting the output control circuit in response to at least the identification information detection signal, and an output circuit (21) for outputting the reproduced signal read from the storage circuit, the identification information addition circuit adding the recording identification information to the digital signal for a given period where the recording circuit initiating recording on the recording medium, and the reset circuit resetting the at least the control circuit upon detection of the recording identification information from the identification information detecting circuit.

摘要： In a video signal processing apparatus, a first or a second video signal having program content information inserted therein is selected. Upon selection of the second signal, the program content information is read from the first video signal and a character signal associated with the program content information is generated and superposed on the selected second video signal. As a result, when the second video signal is supplied to a monitor and an image displayed, a character associated with the character signal is displayed in a part of the particular image which represents that the program content of the first video signal is broadcast by the first video signal. The content of the program which is broadcast by the first video signal is thus determined without interrupting the reception of an image associated with the second video signal.
摘要翻译：在视频信号处理装置中，选择具有插入其中的节目内容信息的第一或第二视频信号。在选择第二信号时，从第一视频信号中读取节目内容信息，并且生成与节目内容信息相关联的字符信号，并叠加在所选择的第二视频信号上。结果，当第二视频信号被提供给监视器和显示的图像时，在特定图像的一部分中显示与字符信号相关联的字符，其表示第一视频信号的节目内容被广播第一个视频信号。由此确定由第一视频信号广播的节目的内容，而不中断与第二视频信号相关联的图像的接收。
