Abstract
Abstract Each of plural electronic devices, e.g., a television receiver, a video disc player, a video tape recorder, an audio amplifier, and a compact disc player which are placed in an audiovisual room has a light emitter and a light detector. Identification signals corresponding to the respective electronic devices are outputted from the light emitters thereof to a single remote control unit. When the remote control unit detects the identification signals, the remote control unit displays on its display unit information required to selectively operate the electronic devices corresponding to the detected identification signals. The remote control unit displays only the information relative to the electronic devices disposed in the audiovisual room. The single remote control unit can control the plural electronic devices in the audiovisual room.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
141 words
An electronic device remote control system comprising: an electronic device placed in a room; and a remote control unit for controlling said electronic device; said electronic device comprising: device identification storing means for storing an assigned identification of the electronic device; device identification signal output means for outputting an identification signal representing said assigned identification for reception by said remote control unit; and control signal detecting means for detecting a control signal outputted from said remote control unit; said remote control unit comprising: control signal output means for outputting the control signal to said electronic device; identification signal detecting means for detecting the identification signal outputted from said electronic device; and display means for displaying a menu required to operate said electronic device corresponding to said identification signal when said identification signal detecting means detects the identification signal in said room.
Claim 2
Dependent Claim
141 words
An electronic device remote control system comprising: an electronic device placed in a room; and a remote control unit for controlling said electronic device; said electronic device comprising: device identification storing means for storing an assigned identification of the electronic device; device identification signal output means for outputting an identification signal representing said assigned identification for reception by said remote control unit; and control signal detecting means for detecting a control signal outputted from said remote control unit; said remote control unit comprising: control signal output means for outputting the control signal to said electronic device; identification signal detecting means for detecting the identification signal outputted from said electronic device; and display means for displaying a menu required to operate said electronic device corresponding to said identification signal when said identification signal detecting means detects the identification signal in said room.
Claim 3
Dependent Claim
38 words
An electronic device control system according to claim 1, comprising a plurality of electronic devices placed in the room, said display means comprising means for displaying a menu keyed to said room for selectively operating said electronic devices.
Claim 4
Dependent Claim
34 words
The system of claim 2 further comprising room remote control unit presence detecting means for causing said plurality of devices to transmit their respective identification signals in response to a remote control presence signal.
Claim 5
Dependent Claim
32 words
The system of claim 2 further comprising one or more additional electronic devices lacking said identification storing means and identification signal output means but nonetheless remotely operable using said remote control unit.
Claim 6
Dependent Claim
29 words
The system of claim 2, said remote control unit being a multifunction microprocessor controlled communication device selected from the group consisting of Personal Intelligent Communicators and Personal Digital Assistants.
Claim 7
Dependent Claim
55 words
An electronic device control apparatus comprising: signal output means for outputting a control signal to control an electronic device; signal detecting means for detecting a device identification signal from said electronic device; and display means for displaying a unique operation menu for said electronic device when said signal detecting means detects said device identification signal.
Claim 8
Dependent Claim
55 words
An electronic device control apparatus comprising: signal output means for outputting a control signal to control an electronic device; signal detecting means for detecting a device identification signal from said electronic device; and display means for displaying a unique operation menu for said electronic device when said signal detecting means detects said device identification signal.
Claim 9
Dependent Claim
86 words
An electronic device control apparatus according to claim 6, further comprising memory means for storing control signals to control a plurality of electronic devices, said signal output means comprising means for reading a control signal required to control one of said electronic devices which corresponds to an identification signal from said memory means and outputting the control signal read from said memory means for subsequent transmission by a remote control user to selectively control said device when said signal detecting means detects said device identification signal.
Claim 10
Independent Claim
83 words
A method of controlling a plurality of electronic devices in a room with a remote control unit, comprising the steps of: pre-assigning different identifications to the electronic devices, respectively; causing the electronic devices to output identification signals uniquely representing the respective devices into a space in the room; and displaying information necessary to selectively operate the electronic devices on a display unit of the remote control unit, said displayed information corresponding to device identification signals the remote control unit detects in said room.
Claim 11
Independent Claim
83 words
A method of controlling a plurality of electronic devices in a room with a remote control unit, comprising the steps of: pre-assigning different identifications to the electronic devices, respectively; causing the electronic devices to output identification signals uniquely representing the respective devices into a space in the room; and displaying information necessary to selectively operate the electronic devices on a display unit of the remote control unit, said displayed information corresponding to device identification signals the remote control unit detects in said room.
Claim 12
Dependent Claim
50 words
A method according to claim 8, wherein said step of causing the electronic devices to output signals comprises the step of causing the electronic devices to output infrared radiations as said device identification signals in response to transmission of a device identification roll call signal by said remote control unit.
Claim 13
Dependent Claim
44 words
The method of claim 8 further comprising the step of correlating a received device identification signal with a room wherein said device is located and displaying said room name, and a device operation menu determined by said room name, on said remote control display.
