Abstract
A signal adapter device for a display system which enables turning on and off the display device for energy conservation. The signal adapter has a signal input port coupled to a signal source, a signal output port coupled to a display, and an adapter port coupled to a sensor. Corresponding pins of the input and output ports are electrically connected to each other, except that the hot plug detect pin of the input port is electrically disconnected from that of the output port but is electrically connected to a hot plug detect pin of the adapter port. The sensor senses environmental conditions such as the presence of viewers within a certain distance, and generates a voltage signal for the hot plug detect pin. Based on this signal on its hot plug detect pin, the signal source determines whether to transmit multimedia data to the display device.
