发明名称 Video signal processing Apparatus.
摘要 <p>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. &lt;IMAGE&gt;</p>
