Abstract:
In case a video display apparatus is connected to a video output apparatus using communication means that disconnects an electrical connection in accordance with stop of power supply from the video output apparatus is operating in an operation mode where an output of video data is restarted after an output of video data is temporarily stopped, control is performed so that the electrical connection is not disconnected. In a state where in accordance with supply power from the video output apparatus, a control signal for establishing an electrical connection via the communication means is in an ON level, in case stop of the power supply is detected, if the video output apparatus is in an operation mode where an output of video data is restarted after an output of video data is temporarily stopped, control is performed so that the control signal is not changed to an OFF level.
