  Hereinafter, embodiments of the present invention will be described. FIG. 1 is a block diagram showing a configuration of a digital audio player (hereinafter, referred to as “DAP”) according to an embodiment of the present invention. DAP1 (display device) outputs analog audio data (audio signal) to headphones 101. The headphones 101 output audio to the outside based on the analog audio data. As shown in FIG. 1, the DAP 1 includes a CPU 2, a storage unit 3, a display unit 4, an operation unit 5, a DSP 6, a D / A converter (hereinafter, referred to as "DAC") 7, amplifiers 8, 9, a wireless module 10, A USB interface (hereinafter, referred to as “USB I / F”) 11 is provided.

  A CPU (Central Processing Unit) 2 (control unit) controls each unit constituting the DAP 1 according to a control program, an OS program, and an application program. The storage unit 3 stores a RAM (Random Access Memory) functioning as a main memory of the CPU 2, a ROM (Read Only Memory) for storing a control program, programs such as an OS program and an application program, and various data such as digital audio data. It is composed of flash memory. Note that the storage unit 3 is not limited to the illustrated configuration, and may include an HDD (Hard Disk Drive) or the like.

  The display unit 4 displays various images (including a still image and a moving image), and includes a liquid crystal panel. The operation unit 5 includes operation keys for performing various settings, and a touch panel in conjunction with the display unit 4. The user can perform various character inputs, settings, and the like via the operation unit 5.

  A DSP (Digital Signal Processor) 6 performs signal processing such as equalizer processing on the digital audio data. The DAC 7 performs D / A conversion of digital audio data into analog audio data. The amplifiers 8 and 9 amplify the analog audio data D / A converted by the DAC 7 and output the amplified audio data to the headphones 101. The wireless module 10 is for performing wireless communication in accordance with the Bluetooth (registered trademark) standard and the Wi-Fi standard. The USB I / F 11 is for performing communication according to the USB standard.

  The DAP 1 stores a database for managing music (content) in the storage unit 3. The database stores the number of plays of each song, each album, and each artist. The CPU 2 reproduces the music selected by the user through the operation unit 5. When the music has been reproduced to the end, the CPU 2 increments the number of reproductions of the music, the album containing the music, and the artist playing the music stored in the database by one.

  FIG. 2 is a flowchart showing the processing operation of DAP1 when updating information stored in the database. As shown in FIG. 2, the CPU 2 reproduces the music, and when the music has been reproduced to the end (S1), increases the number of reproductions of the corresponding music stored in the database by one (S2). Next, the CPU 2 determines whether there is artist information corresponding to the music (S3). When determining that there is artist information corresponding to the music (S3: Yes), the CPU 2 increases the number of times of reproduction of the artist by one (S4). When the CPU 2 determines that there is no artist information corresponding to the music (S3: No), or after the process of S4, it determines whether there is album information corresponding to the music (S5). When determining that there is album information corresponding to the music (S5: Yes), the CPU 2 increases the number of times of reproduction of the album by one (S6). When determining that there is no album information corresponding to the music (S5: No), or after the processing of S6, the CPU 2 ends the processing.

  FIG. 3 is a diagram illustrating an example of the database. Here, the sorting by album is used as a reference. FIG. 3 shows that ten albums with album names “AAA” to “JJJ” are stored in the storage unit 3 of the DAP 1. The album name column stores the album names. The column of the number of times of reproduction stores the number of times of reproduction of the corresponding album. The size column stores size information (large, medium, small). For example, the number of times of reproduction of the album name “AAA” is “30” times, and the size is “small”. In the present embodiment, a threshold for adjusting the size of the album information according to the number of times of reproduction is set as a size threshold. The size threshold value is a value that can be changed. Here, 10% or more of the total number of times of reproduction, the size “large”, 10-20%, the size “medium”, and the size below “size” (default) And

  FIG. 4 is a flowchart illustrating a processing operation of the DAP 1 when the size of the album information is determined according to the number of times of reproduction. The timing of the determination of the size threshold depends on UI (User Interface) transition, such as when the application program is started. As shown in FIG. 4, the CPU 2 acquires total albums from the database in descending order of the number of times of reproduction (S11). Next, the CPU 2 acquires a size threshold (S12). The CPU 2 registers the size “large” in the database as the size of the album exceeding the size threshold (large: 10%) (S13). The CPU 2 registers the size “medium” as the size of the album corresponding to the size threshold (medium: 10-20%) in the database (S14). The CPU 2 registers the size “small” in the size of the other albums in the database (S15).

  FIGS. 5 to 7 are diagrams showing examples of display screens displaying album information in a wall format. As shown in the drawing, the CPU 2 displays album information (content information) on the album (content) on the display unit 4 in a wall format. The CPU 2 arranges the album information on the display unit 4 in a matrix. The size of the album information is of three levels, “large”, “medium”, and “small”. The minimum size “small” of the album information is a size capable of displaying three (predetermined number) album information in one line. The size in the row direction of the album information having the size “large” is three times the size in the row direction of the album information having the size “small”. The size of the “medium” album information in the row direction is twice the size of the “small” album information in the row direction. Therefore, the CPU 2 changes the size of the album information in the row direction up to three times (predetermined number times) based on the number of times the album has been reproduced.

  As shown by the arrow in FIG. 6, the CPU 2 displays the album information from the upper left to the upper right in the ascending order of the album name (AZ). Next, the CPU 2 moves down the line, and similarly displays album information from left to right. In the first line, after displaying the album information “AAA” and the album information “BBB”, the CPU 2 tries to display the album information “CCC”, but the size of the album information “CCC” is “large”. The remaining area in the first row is an area corresponding to the size “small”. Therefore, the CPU 2 cannot display the album information of “CCC” in the remaining area on the first line. Accordingly, the CPU 2 moves to the next line and displays the album information of “CCC” on the second line.

  As shown in FIG. 6, the CPU 2 displays an advertisement in the remaining area on the first line. Alternatively, as shown in FIG. 7, the CPU 2 dynamically changes the album information of "BBB" from the size "small" to the size of "medium" and displays it. That is, the CPU 2 extends the album information of “BBB” displayed before the album information of “CCC” that could not be displayed on the first line to the remaining area.

  FIG. 8 is a diagram showing walls arranged in one row. As shown in FIG. 8, three pieces of album information of a size "small" can be stored in one line. That is, as described above, the minimum album size “small” is a size that can display three pieces of album information in one line. From the left of the wall, X1, X2, and X3.

  FIG. 9 and FIG. 10 are flowcharts showing the processing operation of DAP1 when displaying album information in the wall format. The CPU 2 substitutes 1 for X (S21). Next, the CPU 2 determines whether or not the size of the album information is “small” (S22). When determining that the size of the album information is “small” (S22: Yes), the CPU 2 determines whether X is any one of 1, 2, and 3 (S23). When determining that X is one of 1, 2, and 3 (S23: Yes), the CPU 2 can store the album information of the size “small” in the line, and stores the album information in the area of X. (S24).

  When determining that the size of the album information is not “small” (S22: No), the CPU 2 determines whether the size of the album information is “medium” (S25). When determining that the size of the album information is “medium” (S25: Yes), the CPU 2 determines whether X is any one of 1 and 2 (S26). When determining that X is one of 1 and 2 (S26: Yes), the CPU 2 can store album information of size "medium" in the line, and stores the album information in the area of X (S26: Yes). S24).

  When determining that the size of the album information is not “medium” (S25: No), the CPU 2 determines whether X is 1 or not. (S27). When determining that X is 1 (S27: Yes), the CPU 2 can store album information of the size "large" in the line, and stores the album information in the area of X (S24).

  After the processing in S24, the CPU 2 increases X by 1 (S28). Next, the CPU 2 determines whether or not X is greater than 3 (S29). When determining that X is not larger than 3 (S29: No), the CPU 2 determines whether there is next album information (S30). When determining that there is the next album information (S30: Yes), the CPU 2 performs processing for the next album information (S31). Next, the CPU 2 performs the process of S22. When determining that there is no next album information (S30: No), the CPU 2 ends the process.

  When determining that X is greater than 3 (S29: Yes), the CPU 2 executes the processing shown in FIG. Next, the CPU 2 performs a process for the next line (S32). When determining that X is not any of 1, 2, and 3 (S23: No), and determining that X is not any of 1 and 2 (S26: No), the CPU 2 determines that X is not 1. In this case (S27: No), it is determined whether an advertisement is to be inserted into the remaining area in one line (S33). When determining to insert the advertisement (S33: Yes), the CPU 2 determines and inserts the advertisement size according to (3-X) (S34). When determining that the advertisement is not inserted (S33: No), the CPU 2 extends the album information stored in (X-1) to an area up to "3", that is, to the right end of the line (S35). Next, the CPU 2 performs the process of S32.

  As described above, in the present embodiment, the CPU 2 changes the size of the album information (content information) based on the number of times the album (content) has been reproduced. Therefore, in displaying the album information in the wall format, the visibility of the album information can be enhanced.

  Further, in the present embodiment, the CPU 2 displays the advertisement in the remaining area in one line where the album information could not be displayed. This allows the user to effectively check the advertisement.
