Abstract
A remote control apparatus includes a television monitor capable of displaying an image according to a video signal sent from a camcorder through a video signal line. An operating portion of the remote control apparatus includes keys, and a microcomputer which generates a control signal according to a key input from the keys. The control signal is applied to an infrared ray emitting device when the apparatus is not connected to the camcorder such that the camcorder can be wireless-controlled. If the apparatus is connected to the camcorder through a control signal line and the video signal line, the control signal is applied to the camcorder through the control signal line, and a control signal for controlling a rotation table of the camcorder is applied to the infrared ray emitting device, and therefore, the camcorder can be wire-controlled and the rotation table can be wireless-controlled.
