Abstract

A display device comprises a display component, an output component, a setting component, and a controller. The output component outputs a first signal having guidance information and a second signal having audio information pertaining to content. The setting component performs volume setting. The controller controls output levels of the first signal and the second signal. The controller sets the output level of the first signal to a value that is greater than or equal to the output level of the second signal, and sets the output level of the first signal to a value greater than zero when the output level of the second signal is zero.

Claims

1. A display device comprising:

a display component;

a speaker that outputs a first signal having guidance information pertaining to a user operation performed relative to the display device or a status of the display device and a second signal having audio information pertaining to content, the speaker outputting the first signal in response to the user operation;

a receiver that receives volume setting that sets a volume setting value of the display device;

a controller that sets output levels of the first signal and the second signal to values corresponding to the volume setting value that has been set by the volume setting, respectively, the controller setting the output level of the first signal to a value that is greater than or equal to the output level of the second signal, and setting the output level of the first signal to a value greater than zero while the output level of the second signal is zero; and

a table in which the output levels of the first signal and the second signal are respectively associated with the volume setting value such that difference between the output level of the first signal and the output level of the second signal at a specific volume setting value being greater than difference between the output level of the first signal and the output level of the second signal at a volume setting value that is greater than the specific volume setting value,

the controller automatically setting the output levels of the first signal and the second signal based on the table such that difference between the output level of the first signal and the output level of the second signal decreases as the volume setting value that has been set by volume setting increases.

2. The display device according to claim 1, wherein

a change amount in the output level of the first signal due to a specific change in the volume setting value is a value less than or equal to a change amount in the output level of the second signal due to the specific change in the volume setting value.

3. The display device according to claim 1, wherein

a change rate in the output level of the first signal relative to the volume setting value is less than or equal to a change rate in the output level of the second signal relative to the volume setting value.

4. The display device according to claim 3, wherein

the change rate in the output level of the first signal relative to the volume setting value is equal to the change rate in the output level of the second signal relative to the volume setting value for a specific range of the volume setting value.

5. The display device according to claim 1, wherein

the output level of the first signal is a value that falls within a specific range.

6. The display device according to claim 5, wherein

a settable volume range of the volume setting is set to a range in which the output level of the first signal is greater than or equal to the output level of the second signal.

7. The display device according to claim 1, wherein

the table includes a first table in which specific output levels of the first signal are associated with the volume setting value, and a second table in which output levels different from the specific output levels of the first signal are associated with the volume setting value, and

the controller controls the output level of the first signal based on either the first table or the second table.

8. The display device according to claim 1, wherein

the controller performs control to change both the output levels of the first signal and the second signal along with a change in the volume setting value.

9. The display device according to claim 1, wherein

the first signal is audio that conveys at least one of information related to an operation carried out on the display device, and information related to status of the display device.

10. The display device according to claim 1, wherein

the second signal is audio related to video displayed on the display component.

11. The display device according to claim 1, further comprising

a receiver that receives broadcast signals,

the second signal corresponding to audio from the receiver.

12. The display device according to claim 1, further comprising

an input unit to which audio from an external device is inputted,

the second signal corresponding to the audio inputted to the input unit.

13. A display device comprising:

a display component;

a speaker that outputs a first signal having guidance information pertaining to a user operation performed relative to the display device or a status of the display device and a second signal having audio information pertaining to content, the speaker outputting the first signal in response to the user operation;

a receiver that receives volume setting that sets a volume setting value of the display device;

a controller that sets output levels of the first signal and the second signal to values corresponding to the volume setting value that has been set by the volume setting, respectively, the controller setting the output level of the first signal to a value that is greater than or equal to the output level of the second signal, and setting the output level of the first signal to a value greater than zero while the output level of the second signal is zero; and

a table in which the output levels of the first signal and the second signal are respectively associated with the volume setting value such that difference between the output level of the first signal and the output level of the second signal at a specific volume setting value and difference between the output level of the first signal and the output level of the second signal at a volume setting value that is different from the specific volume setting value being substantially equal values over a predetermined range from a first volume setting value to a second volume setting value that is greater than the first volume setting value, and such that a change amount in the output level of the first signal due to a specific change in the volume setting value outside the predetermined range being a value less than or equal to a change amount in the output level of the second signal due to the specific change in the volume setting value outside the predetermined range,

the controller automatically setting the output levels of the first signal and the second signal based on the table such that difference between the output level of the first signal and the output level of the second signal decreases as the volume setting value that has been set by volume setting increases outside the predetermined range.

14. The display device according to claim 13, wherein

the output level of the first signal is a value that falls within a specific range over a range of volume setting values that are greater than the second volume setting value.

15. The display device according to claim 13, wherein

the output level of the first signal is a value that falls within a specific range over a range of volume setting values that are less than or equal to the first volume setting value.

16. The display device according to claim 15, wherein

the first volume setting value is a volume setting value at a midpoint in a settable volume range.

17. The display device according to claim 13, wherein

the output level of the first signal and the output level of the second signal are substantially equal values at the specific volume setting value over the predetermined range from the first volume setting value to the second volume setting value.

18. The display device according to claim 13, wherein

the output level of the first signal and the output level of the second signal are different values at the specific volume setting value over the predetermined range from the first volume setting value to the second volume setting value.
