Abstract:
1. A video processing apparatus comprising: a signal receiving unit configured to receive signals from a plurality of external video processing apparatuses, each received signal including identification information for identifying an external video processing apparatus transmitting the signal, among the plurality of external video processing apparatuses; a signal transmitting unit configured to transmit another signal to at least one of the plurality of external video processing apparatuses; a video processing unit configured to process the signal received in the signal receiving unit; and a controller configured to selectively supply or cut off electric power to the video processing unit according to whether the signal receiving unit receives the signal, and to selectively supply or cut off electric power to the signal transmitting unit to control the external video processing apparatus to turn off or on according to whether the signal receiving unit receives the signal, wherein, in response to the signal receiving unit not receiving the signal from the external video processing apparatus, the controller cuts off the electric power to the video processing unit and cuts off the electric power to the signal transmitting unit, while maintaining power to the signal receiving unit, to control the external video processing apparatus to turn off, and wherein the controller determines whether the signal receiving unit receives the signal from a first apparatus of the plurality of external video processing apparatuses, based on the identification information respectively received from the plurality of external video processing apparatuses, and performs the selectively supplying or cutting off the electric power corresponding to only when receiving the signal from the first apparatus among the plurality of external video processing apparatuses.
