Abstract

An object is to provide a radio wave receiver capable of enhancing user-friendliness regarding a display of intensity of a received radio wave in a configuration capable of utilizing two different kinds of radio waves.

Each radio wave processing portion 1, 2 receives a radio wave, and outputs various kinds of information such as video information (video signal, video data), audio information (audio signal, audio data), and another information (location information, etc.). A switching portion 4 inputs output signals of the first, and second radio wave processing portions 1, 2, selects the output signals according to a switching instruction of a controller 3, and supplies the output signals to a display portion 6 and a speaker 7. In obtaining a power voltage value indicating intensity (intensity of received electrical fields) of received radio waves from each tuner 11, 21, the controller 3 controls a display of the intensity of the received radio waves in both tuners, even if the controller 3 processes the radio wave of one, or both the tuners, and controls a display of the intensity of the received radio waves by switching the intensity of the radio waves received in both tuners based on an operation of an operating portion 5 by a user.

Claims

1. A radio wave receiving apparatus provided with a first radio wave receiving portion and a second radio wave receiving portion, and receiving two different radio waves, comprising:

a means for obtaining information indicating intensity of received radio waves from each radio wave receiving portion;

a display for executing a display indicating the intensity of the received radio waves;

a means for generating display information applied to the display based on the information indicating the intensity; and

a controller for switching, based on an user operation, between a display of the intensity of the received radio wave of the radio wave receiving portions receiving a radio wave, which is a subject to be processed, and a display of the intensity of the received radio wave of the radio wave receiving portion receiving a radio wave, which is a subject not to be processed.

4. A radio wave receiving apparatus according to any one of claims 1 to 3, wherein the display indicating the intensity of the received radio waves is performed by using pictographic characters.

5. A radio wave receiving apparatus according to claim 4, wherein there is a difference in color between the pictographic characters indicating the intensity of the radio wave of the radio wave receiving portion receiving the radio wave, which is a subject to be processed, and the pictographic characters indicating the intensity of the radio wave of the radio wave receiving portion receiving the radio wave, which is a subject not to be processed.

6. A radio wave receiving apparatus according to claim 4, wherein there is a difference in shape between the pictographic characters indicating the intensity of the radio wave of the radio wave receiving portion receiving the radio wave, which is a subject to be processed, and the pictographic characters indicating the intensity of the radio wave of the radio wave receiving portion receiving the radio wave, which is a subject not to be processed.

2. A radio wave receiving apparatus provided with a first radio wave receiving portion and a second radio wave receiving portion, and receiving two different radio waves, comprising:

a means for obtaining information indicating intensity of received radio waves from each radio wave receiving portion;

a display for executing a display indicating intensity of the two received radio waves at the same time; and

a means for generating two pieces of display information applied to the display based on information indicating intensity of the both received radio waves of the radio wave receiving portion receiving a radio wave, which is a subject to be processed, and the radio wave receiving portion receiving a radio wave, which is a subject not to be processed.

3. A radio wave receiving apparatus provided with a first radio wave receiving portion and a second radio wave receiving portion, and receiving two different radio waves, comprising:

a means for obtaining information indicating intensity of received radio waves from each radio wave receiving portion;

a display capable of forming a display state showing the intensity of two received radio waves at the same time, and a display state showing the intensity of one received radio wave;

a means for generating display information applied to the display based on the information indicating the intensity; and

a controller for switching, based on a user operation, among a first display mode indicating intensity of the received radio wave of the radio wave receiving portion receiving a radio wave, which is a subject to be processed, a second display mode indicating intensity of the received radio wave of the radio wave receiving portion receiving a radio wave, which is a subject not to be processed, and a third display mode indicating intensity of the both received radio waves.
