A SYSTEM FOR SENSING AND COORDINATING THE ON/OF STATE OF A DISPLAY WITH THE ON/OF STATE OF A MEDIA DEVICE

摘要

A system for sensing and coordinating the on/off state of a display (15) with the on/off state of a media device, comprising: a display (15); a sensor (20), proximate to said display (15), configured to detect electromagnetic radiation generated by said display (15); and at least one signal processing means configured to process a signal received from said sensor (20); characterized in that said at least one signal processing means (35, 40, 45) further includes broadband filtering means (35) operable to process the signal from the sensor with a bandwidth substantially greater than 1/3 octave, and wherein said at least one signal processing means (35, 40, 45) outputs a signal representative of the on/off state of said display (15), wherein said at least one signal processing means (35, 40, 45) is further configured to determine an on/off state of said media device, said media device further comprising a processor means (50) in communication with said display (15) and with said at least one signal processing means, wherein said processor means (50) is further configured to coordinate said display on/off state with said media device on/off state.
