Home bus information display system

Abstract

Abstract PURPOSE:To realize concentrated monitoring of a control state of plural apparatuses by connecting plural apparatuses and a television receiver with a bus line, displaying the control state of those plural apparatuses superposed on a TV screen of its television receiver, and also, selectively deleting its superposed display. CONSTITUTION:To a coaxial cable 4, a television receiver 6, a (VCR) 10, a video disk reproducing device 13 and an audio device 16 are connected through branch devices 3, 8, 11 and 14 and branch coaxial cables 5, 9, 12 and 15, respectively, and one terminal of a signal switching device 19 is connected through a branch device 17 and a branch coaxial cable 18. Also, to an AC power source line 21 in a general household, the other terminal of the signal switching device 19 is connected through a branch line 22. The signal switching device 19 superposes a control signal flowing through a coaxial cable 4 to an AC power source line 21, and also, extracts a control signal or a control state signal superposed on the AC power source line 21 and transmits it to the coaxial cable 4 side. In such a way, on a video screen of the receiver 6, information for showing a control state of the apparatuses 10, 13, 16, etc., is superposed and displayed, and also, at every apparatus, a deletion of each superposed display can be selected.
