ABSTRACT:
A video system comprising a video camera and a recording device to record video signals obtained by the video camera. The recording device includes a video tape recorder (VTR) which may be combined with the video camera when recording and otherwise may be combined with a reproduction unit. Mode switches in the VTR are changed over depending on the combination desired. When the VTR is used with the camera, the combination records sound, video signal and controls signals on a tape wound around a drum. A system control circuit controls various motors and solenoids control operation of the VTR. Power supply to the system is controlled by a power source switch in the VTR, which element provides "OFF", "STANDBY I" and "STANDBY II" modes. Delay elements operate in the two standby modes. When the power source switch is in either standby mode, loading is done automatically. One standby mode provides power to a rotating system and the other mode provides no power. The delay elements provide different delay times for each mode so that triggering of the camera can be made with due consideration for the start up time of the rotating system. The built-in delays are effective in conserving power.
