发明名称 Video switcher
摘要 A video switching apparatus in which an operating mode (recording/reproduction) of a recording/reproducing apparatus is discriminated from a video output signal of the recording/reproducing apparatus by recording/reproduction detecting portion, thereby enabling an automatic switching of a setting mode of the video switching apparatus. It is possible to prevent recording failures which may be otherwise caused due to an inconsistency between the mode settings of the video switching apparatus and the recording/reproducing apparatus connected thereto.
