It may further include.

The display information may be a scale bar indicating that the parameters are continuous by arranging a plurality of scales.

Hereinafter, with reference to the drawings will be described the present invention in more detail.

1 is a block diagram of an audio playback apparatus according to an embodiment of the present invention. This audio reproducing apparatus is a device which reproduces audio data stored in itself and provides it to a user. In addition, the audio reproducing apparatus has a function of receiving a radio broadcast and a function of recording audio input through an external microphone.

As shown in FIG. 1, the audio playback apparatus includes an external input unit 110, a radio receiver 120, a storage unit 130, an audio codec 140, a controller 150, an operation unit 160, and an external output. A unit 170, an internal output unit 180, a GUI generator 190, and an LCD 200 are provided.

The external input unit 110 converts audio input through an external microphone into a digital audio signal. The radio receiver 120 receives / demodulates a radio broadcast of a tuned frequency. The audio signal obtained from the external input unit 110 or the radio receiver 120 is output to the earphone through the external output unit 170 or to the internal output unit 180 such as a built-in speaker.

The audio codec 140 expands (decompresses) audio data stored in the storage 130. The expanded audio data is output to the external output unit 170 or the internal output unit 180.

The controller 150 controls the overall operation of the present audio reproducing apparatus according to a user's manipulation command input through the manipulation unit 160. In particular, the controller 150 controls the GUI generator 190 to display a GUI screen necessary for the situation.

When the audio reproducing apparatus is in the 'radio receiving mode', a GUI screen generated by the GUI generating unit 190 under the control of the controller 150 and provided to the user through the LCD 200 is illustrated in FIG. 2.

As illustrated in FIG. 2, the frequency screen 190A, the scale bar area 190B, the pointer 190C, and the frequency moving direction 190D are displayed on the GUI screen provided in the radio reception mode.

The frequency domain 190A is an area where numeric information about a radio broadcast frequency selected by a user through the manipulation unit 160 and tuned through the radio receiver 120 appears.

The scale bar area 190B is an area where a scale bar, which is a kind of graphic information in the form of an instrument panel in which several scales are arranged in a straight line, appears. This makes it intuitive to the user that the radio broadcast frequencies are continuous and that frequencies can be increased or decreased.

The pointer 190C is display information indicating the relative position of the tuned frequency on the scale bar 190B. The pointer 190C appears superimposed on the scale bar.

The frequency moving direction 190D is display information indicating the change direction when there is a change in the radio broadcasting frequency. The frequency moving direction 190D consists of a left-right indication and a right-right indication. When the radio broadcast frequency increases, the right direction indication is activated and the left direction indication is deactivated. On the other hand, when the radio broadcast frequency decreases, the left direction indication is activated and the right direction indication is deactivated.

In detail, the GUI generating unit 190 shows an increased frequency in the frequency region 190A (S420), and shows a “scale bar ⑭” among the scale bars shown in FIG. 3 in the scale bar region 190B (S430). 3, the pointer 190C shown in FIG. 3 is shown slightly to the right (for example, two points to the right) from the center of the scale bar (S440).

The GUI screen generated through steps S420 to S440 is displayed on the LCD 450 (S450).

If 100 ㎳ elapses after the GUI screen is displayed (S460-Y), the controller 150 controls the GUI generator 190 to generate another GUI screen (S470 ˜ S480). Specifically, the GUI generating unit 190 represents the "bar 1" of the scale bars shown in FIG. 3 in the scale bar area 190B (S470), and the pointer 190C shown in FIG. 3 is positioned at the center of the scale bar. It is shown in (S480).

The GUI screen generated through steps S470 and S480 is displayed on the LCD 450 (S490).

When the GUI screen is displayed by the above process, when the increased frequency is displayed, the scales of the scale bars are slightly moved to the left side and the pointer is slightly moved to the right side and then returned to the original position while being restored to the original position. This display process allows the user to feel the intermittent increase in frequency in more vivid graphics.

Hereinafter, the GUI screen provided when the radio broadcast frequency is decreased will be described in detail with reference to FIG. 5.

Tuning the signal (S510). For example, if the currently tuned frequency is 93.2 MHz, the reduced frequency is 93.1 MHz.

Thereafter, the controller 150 controls the GUI generator 190 to generate a GUI screen (S520 to S540). In detail, the GUI generating unit 190 shows a reduced frequency in the frequency region 190A (S520), and shows a “scale bar ②” among the scale bars shown in FIG. 3 in the scale bar region 190B (S530). 3 shows the pointer 190C shown in FIG. 3 slightly to the left of the center of the scale bar (for example, two points to the left) (S540).

The GUI screen generated through steps S520 to S540 is displayed on the LCD 450 (S550).

If 100 ㎳ elapses after the GUI screen is displayed (S560-Y), the controller 150 controls the GUI generator 190 to generate another GUI screen (S570 ˜ S580). In detail, the GUI generating unit 190 indicates “ticle bar ①” among the scale bars shown in FIG. 3 in the scale bar area 190B (S570), and moves the pointer 190C shown in FIG. 3 to the center of the scale bar. It is shown in (S580).

The GUI screen generated through steps S570 and S580 is displayed on the LCD 450 (S590).

When the GUI screen is displayed by the above process, when the reduced frequency is displayed, the scales of the scale bars are slightly moved to the right and the pointer is slightly moved to the left and then returned to the original position. This display process allows the user to feel the intermittent reduction of frequency in more vivid graphics.

The GUI screen generated through steps S620 to S630 is displayed on the LCD 450 (S635).

When 100 ms has elapsed after the GUI screen is displayed (S640-Y), the controller 150 controls the GUI generator 190 to generate another GUI screen (S645 to S650). In detail, the GUI generating unit 190 indicates “scale bar n + 1” among the scale bars shown in FIG. 3 in the scale bar area 190B (S645), and displays the pointer 190C shown in FIG. 3 in the scale bar. In the center of (S650).

The GUI screen generated through the steps S645 and S650 is displayed on the LCD 450 (S655).

Thereafter, if it is determined that the current frequency is less than or equal to the maximum frequency (S660-Y), the controller 150 increases the variable n by "2" (S665). If it is determined that n exceeds 14 (S670-Y), the controller 150 changes the variable n to "1" (S675).

Then, the controller 150 controls the radio receiver 120 to tune the radio broadcast signal of the increased frequency (S680), and then executes the process again from step S615.
