Abstract

Abstract The present invention is concerned with an audio equipment capable of processing video signals and a method of displaying operation of the acoustic equipment. An input selector switch 1 is supplied with reproduced audio signals from devices connected to a tuner unit 2 and input terminals 3, and supplies a signal to a sound field processing DSP unit 4. A signal processed by the DSP unit 4 is applied through a muting switch 5 to an output terminal 6. An input selector switch 7 is supplied with reproduced video signals from devices connected to input terminals 8, and supplies a signal to a graphic controller (GDC) 9 which generates a video signal to display an image. One of a signal generated by the GDC 9 and an original video signal are selected by a switch 10, and applied to an output terminal 11. The GDC 9 also generates an image simulating a control panel. When a key switch 13 is operated, the display corresponding to the operated key in the simulating image is varied.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 143 words
A method of displaying operation of an audio equipment in a room in which an user is situated, comprising the steps of: producing an image signal to display an image indicative of a sound field; detecting a setting of a parameter of a material of a wall surface around the sound field, the parameter of the material of the wall surface around the sound field being desirably set according to an actual material of a wall surface in the room; and varying a portion of the image corresponding to the wall surface around the sound field in accordance with the setting of the parameter of the material of the wall surface around the sound field, wherein the setting of the parameter of the material of the wall surface around the sound field is visually confirmed by the corresponding varying portion of the image.
Claim 2
Independent Claim 143 words
A method of displaying operation of an audio equipment in a room in which an user is situated, comprising the steps of: producing an image signal to display an image indicative of a sound field; detecting a setting of a parameter of a material of a wall surface around the sound field, the parameter of the material of the wall surface around the sound field being desirably set according to an actual material of a wall surface in the room; and varying a portion of the image corresponding to the wall surface around the sound field in accordance with the setting of the parameter of the material of the wall surface around the sound field, wherein the setting of the parameter of the material of the wall surface around the sound field is visually confirmed by the corresponding varying portion of the image.
Claim 3
Independent Claim 151 words
A method of displaying operation of an audio equipment in a room in which a user is situated, comprising the steps of: varying acoustic characteristics corresponding to a setting of a sound field in accordance with operation of an operation unit by the user; producing an image signal to display an image corresponding to the set sound field; and varying a portion of the displayed image corresponding to a wall material around the sound field in accordance with a parameter setting of a material of the wall surface around the sound field, the parameter of the material of the wall surface around the sound field being desirably set according to an actual material of a wall surface in the room, wherein the setting of the parameter of the material of the parameter of the wall surface around the sound field is visually confirmed by the corresponding portion of the displayed image.
Claim 4
Independent Claim 151 words
A method of displaying operation of an audio equipment in a room in which a user is situated, comprising the steps of: varying acoustic characteristics corresponding to a setting of a sound field in accordance with operation of an operation unit by the user; producing an image signal to display an image corresponding to the set sound field; and varying a portion of the displayed image corresponding to a wall material around the sound field in accordance with a parameter setting of a material of the wall surface around the sound field, the parameter of the material of the wall surface around the sound field being desirably set according to an actual material of a wall surface in the room, wherein the setting of the parameter of the material of the parameter of the wall surface around the sound field is visually confirmed by the corresponding portion of the displayed image.
