Description

  The present invention relates to a content data reproducing apparatus and a control method.

In recent years, portable data playback devices such as compact disc players and portable audio players with built-in hard disks are often used particularly outdoors, and the size has been further reduced.
However, along with this miniaturization, the operation part composed of buttons and the like necessary for the user to control the data reproducing apparatus is also miniaturized, and the user needs to appropriately operate small buttons and the like. .

In addition to the basic functions such as playback and stop, the data playback device is multi-functional, as well as a repeat setting function, a random setting function, a function for efficiently selecting data from a huge amount of data, etc. Has come to be added.
However, with this multi-functionalization, the user has required a huge number of operations on the miniaturized operation site.

  That is, the user needs to perform precise operations on the downsized operation site, and the number of operations is enormous. That is, there has been a problem that the operability of the data reproducing apparatus is lowered.

In order to solve such a problem, it is possible to measure the pressing time of the operation button arranged at the operation site and determine whether or not the measured time has exceeded an arbitrary fixed time by using one operation button. An operation mode control device capable of a plurality of operations is disclosed (for example, see Patent Document 1).
Japanese Patent Publication No. 06-101190

However, since the above-described operation mode control device measures the pressing time of the operation button, the response to pressing of the operation button is poor compared to a device that does not measure the pressing time.
Further, even if the above-described operation mode control device can perform a plurality of operations with one operation button, it is difficult for the user to intuitively understand the operation method, and as a result, the operability is low.

  According to the content data reproducing apparatus of the present invention, the user can easily understand the operation intuitively without increasing the number of operation buttons and deteriorating the response to pressing of the operation button, and realizing high operability. .

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing an example of a portable music device 100 applied to the embodiment of the present invention. The portable music device 100 is a device capable of reproducing data stored in the storage unit 103 (for example, music data such as MP3 (MPEG1 Audio Layer-3)), and includes an operation unit 102, a storage unit 103, and a control. Unit 101, display unit 104, terminal 118, and earphone 119 are included. The user can listen to the reproduced music through the earphone 119.

  The operation unit 102 includes predetermined button keys, rotary keys, and the like, and inputs instruction information in accordance with user operations. For example, the operation unit 102 includes a reproduction execution key 112. Here, the reproduction execution key 112 is a double tact key that can be physically pressed in two stages. The first-step pressing and the second-step pressing of the reproduction execution key 112 generate separate analog signals using a resistance voltage dividing circuit connected to the tact key.

  The configuration of the resistance voltage dividing circuit connected to the reproduction execution key 112 will be described with reference to FIG. The resistance voltage dividing circuit includes a resistor R1, a resistor R2, a resistor R3, a resistor R4, a switch S1, and a switch S2. The switch S1 is turned on when the reproduction execution key 112 is pressed in the first stage (hereinafter referred to as weak pressing), and the switch S2 is turned on when the reproduction execution key 112 is pressed in the second stage (hereinafter, strong pressing). Called push).

  When the tact key is not pressed, the output voltage Vout is (R2 / (R1 + R2)) × power supply voltage Vcc. The reproduction execution key 112 includes resistors R2, R3, and R4 having different resistance values. By pressing the reproduction execution key 112 in the first stage, the output voltage Vout becomes ((R2 // R3)) / (R1 + (R2 // R3))) × power supply voltage Vcc. Further, when the reproduction execution key 112 is pressed in the second stage, the output voltage Vout is configured to be ((R2 // (R3 + R4)) / (R1 + R2 // (R3 + R4))) × power supply voltage Vcc. As a result, the resistance voltage dividing circuit can supply the output voltage Vout to the control unit 101 differently depending on whether the reproduction execution key 112 is pressed at the first stage or the second stage.

  With the resistance voltage dividing circuit of FIG. 2 described above, the operation of each key of the operation unit 102 (the weak press and the strong press of the reproduction execution key 112) outputs a different output voltage Vout. The output voltage Vout is output from the operation unit 102 and input to the A / D converter 109.

  Returning to FIG. 1, the storage unit 103 includes a storage device such as a hard disk. The storage unit 103 stores, in addition to data such as music data, hierarchical information that defines a file structure such as music data. For example, music data is composed of a file structure as shown in FIG. 3, and music data having a common artist name in the meta information is bundled in a folder corresponding to the hierarchical level 1 and the common album name is set in the meta information. The music data included in the information is collectively stored in a folder corresponding to the hierarchical layer 2 of the hierarchical structure. At this time, the hierarchical information that defines the file structure is stored in the storage unit 103 together with the music data.

The hierarchical information includes a folder table 401 as shown in FIG. 4A and a data management table 402 as shown in FIG. 4B.
A folder table 401 shown in FIG. 4A is a folder that stores data stored in the storage unit 103, that is, one folder (currently a current execution target) among folders that are management units of hierarchical data. This is a table for managing data in a folder. Specifically, the folder table 401 stores a plurality of folders belonging to the current folder, or folder / file names for identifying music data and data numbers. For example, in the file structure as shown in FIG. 3, if the current folder is folder (1), the folder table 401 includes folder names (1: 1) and folder names (1: 2) and the corresponding folder names. A data number is stored.

  On the other hand, the data management table 402 shown in FIG. 4B is a table for managing music data to be selected. Specifically, the data management table 402 includes a folder name (eg, artist name, album name) of the current folder, a hierarchy number indicating the hierarchy order (hierarchy depth) where the current folder is located, and the current folder The target data number for specifying one data to be selected and the total number of data indicating the total number of data belonging to the current folder are stored. For example, in the file structure as shown in FIG. 3, if the current folder is a folder (2: 1), the hierarchy number is “002” and the total number of data is “006”.

  Returning to FIG. 1, the control unit 101 includes, for example, a CPU (Central Processing Unit) 105, an interrupt controller 108, an A / D converter 109, a RAM (Random Access Memory) 107, a ROM (Read Only Memory) 106, and an audio signal output unit. 111, the signal amplifier 110, and the like, and the CPU 105 appropriately executes various programs (reproduction control program 114, search mode setting program 115, key code processing application 116, key processing driver 117, etc.) stored in the ROM 106. Thus, the operation of the portable music device 100 is controlled, and the CPU 105 may have a timer for measuring the time when the reproduction execution key 112 is pressed.

  The interrupt controller 108 is connected between the CPU 105 and the operation unit 102, receives an interrupt request from the operation unit 102, and causes the CPU 105 to generate an interrupt request signal.

  The A / D converter 109 converts the analog signal supplied from the operation unit 102 into a digital signal and outputs it.

  The RAM 107 is used as a work memory for loading reproduction data or the like when the CPU 105 executes a program.

  The ROM 106 is a read-only storage device. The ROM 106 stores information (programs) that does not need to be rewritten, such as the reproduction control program 114, the search mode setting program 115, the key code processing application 116, and the key processing driver 117 described above.

  The reproduction control program 114 is a program for loading music data stored in the storage unit 103 to the RAM 107 and reproducing it based on an instruction signal from the operation unit 102. Specifically, the music data is loaded into the RAM 107, and this music data is supplied to, for example, an MP3 decoder (not shown) and decoded, and further supplied to the audio signal output unit 111 to receive audio data (analogue). Signal) is output to the signal amplifier 110.

  The search mode setting program 115 is a program for searching for data desired by the user from a vast amount of music data stored in the storage unit 103. Specifically, a list of album names is displayed on the display unit 104, an album search mode in which desired music data can be searched from the album name, and a list of artist names are displayed on the display unit 104. Switch to artist search mode that allows you to search for music data.

For example, when searching for song data in the album search mode, the scroll state of highlights on a GUI (Graphical User Interface) is displayed on the display unit 104 as shown in FIG. Display. This is because the folder name of each folder whose hierarchy number is 002 in the data management table 402 is displayed at an appropriate position on the GUI, or a highlight is displayed on the file name specified by the target data number in the data management table 402. Thus, the desired data can be searched.
Further, when searching for music data in the artist search mode, it is displayed on the display unit 104 as shown in FIG. This is because the folder name of each folder whose hierarchy number is 001 in the data management table 402 is displayed at an appropriate position on the GUI, or a highlight is displayed on the file name specified by the target data number in the data management table 402. Thus, the desired data can be searched.

  The key processing driver 117 performs a bridge for the CPU 105 to supply a key code to a key code processing application 116 described later. Specifically, the instruction information (analog signal) input from the user via the operation unit 102 is generated from the digital signal once input through the A / D converter 109 and supplied to the CPU 105.

  The key code processing application 116 is supplied with the key code generated by the key processing driver 117, determines processing by key input based on the supplied key code, and supplies this to the CPU 105. As a result, operations corresponding to different operations of the user in the operation unit 102 are executed. Specifically, the operation unit 102, the A / D converter 109, the reproduction control program 114, the search mode setting program 115, the key processing driver 117, the key code processing application 116, and the CPU 105 cooperate to operate the operation unit. Based on the instruction signal from 102, the search mode is appropriately switched.

  More specifically, the instruction information (analog signal) input from the user via the operation unit 102 is the output voltage Vout distinguished for each tact key as described above. The key processing driver 117 assigns a different digital signal via the A / D converter 109 to each of these different output voltages Vout, and uses this as a key code corresponding to the operation as a key code processing application 116 via the CPU 105. To supply. For example, a key code “010” is supplied when the reproduction execution key 112 is pressed strongly by the user, and a key code “011” is supplied when the reproduction execution key 112 is weakly pressed by the user. Also good.

  The audio signal output unit 111 includes a D / A converter that converts music data read from the storage unit 103 into an analog signal and outputs the analog signal.

  The signal amplifier 110 is an analog circuit that amplifies the music data (analog signal) read from the storage unit 103 to the audio signal output unit 111 and outputs the music data (analog signal) to the earphone 119 via the terminal 118.

The display unit 104 includes a flat panel display such as a fluorescent display tube (VFD) and a liquid crystal display (LCD), and is controlled by the control unit 101 to clarify the operation status to the user. The character string etc. for displaying are displayed.
In addition, for example, a display area for 8 lines for displaying the contents of the folder table 401 stored in the storage unit 103 is arranged in the display unit 104.

  In the above, each structure in Embodiment 1 of this system has been described.

  Next, a specific operation of this apparatus having the above configuration will be described with reference to the flowchart of FIG.

  FIG. 6 is a flowchart for explaining the search mode setting process. The search mode setting process shown in FIG. 6 is started by an interrupt input by pressing a key arranged on the operation unit 102.

  The CPU 105 of the control unit 101 determines which key is pressed when this interrupt is input. This is determined by the key code supplied from the key processing driver 117 as described above.

  If the CPU 105 determines that the pressed key is not the reproduction execution key 112 (step S101; No), the search mode setting process ends as another process.

  If it is determined in step S101 that the reproduction execution key 112 has been pressed (step S101; Yes), the CPU 105 determines whether or not the reproduction execution key 112 has been pressed hard (step S102). As described above, the pressed state of the reproduction execution key 112 is determined by the key processing driver 117. When it is determined that it is not a strong press (step S102; No), since the pressed state of the playback execution key 112 is a weak press, the CPU 105 develops the playback control program 114 in the RAM 107 and executes a music data playback process (step S103). ). Here, the CPU 105 ends the search mode setting process.

  On the other hand, when the CPU 105 determines in step S102 that the pressed state of the reproduction execution key 112 is a strong press (step S102; Yes), the search mode setting program 115 is expanded in the RAM 107 and activated. In order to make the pressed state of the reproduction execution key 112 of this embodiment strong, it is necessary to make the pressed state weak once. Therefore, in step S102, the CPU 105 may measure the pressing time with a timer and determine whether the pressing state of the reproduction execution key 112 is a strong pressing or a weak pressing when the pressing state continues for a predetermined time. .

  Here, the CPU 105 determines whether or not the current search mode is set to OFF (step S104). Specifically, the determination is made with reference to a file in which information (variables) corresponding to the current search mode overwritten according to the search mode setting program 115 is written.

  When determining that the search mode is set to OFF (step S104; Yes), the CPU 105 sets the search mode to the album search mode (step S105). Specifically, the CPU 105 overwrites information corresponding to the album search mode on the file in the storage unit 103. Then, as shown in FIG. 5A, a list of album names is displayed on the display unit 104 so that desired data can be searched. After the setting, the CPU 105 ends the search mode setting process.

  On the other hand, when it is determined in step S104 that the search mode is not set to OFF (step S104; No), the CPU 105 determines whether or not the current search mode is set to the album search mode (step S106). ). When determining that the current search mode is set to the album search mode (step S106; Yes), the CPU 105 sets the search mode to the artist search mode (step S107). Specifically, the CPU 105 overwrites information corresponding to the artist search mode on the file in the storage unit 103. Then, as shown in FIG. 5B, a list of artist names is displayed on the display unit 104 so that desired data can be searched. After the setting, the CPU 105 ends the search mode setting process.

  On the other hand, if it is determined in step S106 that the search mode is not set to the album search mode (step S106; No), the CPU 105 sets the current search mode to OFF (step S108). After the setting, the CPU 105 ends the search mode setting process.

The search mode setting process described above is performed in the control unit 101 of the portable music device 100 according to the present embodiment, so that the search mode setting program 115 can be quickly called and the search mode can be set with a simple operation. Become.
In addition, since the frequently used key such as the play execution key 112 is also used as a search mode setting function, the portable music device 100 according to the present embodiment has no problem in reducing the size of the operation unit 102 and is intuitive to the user. Realize easy-to-understand operations.
Furthermore, the reproduction execution key 112 is a key provided in any portable music device, and can standardize operation specifications.

  In addition, this invention is not limited to said each embodiment, A various deformation | transformation and application are possible.

  For example, in the above embodiment, the album search mode and the artist search mode are switched by pressing the reproduction execution key 112 strongly. However, the present invention is not limited to this, and may be switched to another search mode related to common meta information of music data. For example, you may switch to the mode etc. which search desired data by the genre of music data. There may be only one search mode. In this case, the predetermined search mode is turned on / off by pressing the reproduction execution key 112.

  Further, in each of the above embodiments, the reproduction execution key 112 is a double tact key that can be pressed in two stages. However, the present invention is not limited to this, and may be a multi-tact key that can be pressed in a plurality of stages, such as three stages, four stages, and the like. In this case, a combination of resistors and switches shown in FIG. 2 may be added as appropriate so that different voltages are output.

In addition, the present invention can be implemented by combining other embodiments. For example, the above embodiment and other embodiments may be performed simultaneously. In this case, as described above, the reproduction execution key is used as a multi-tact key, and pressing at each stage may be assigned to each function. Specifically, the reproduction execution key is a triple tact key, and the above-described embodiment is performed when the second step is strongly pressed, and the other embodiments are performed when the third step is strongly pressed. .
Further, instead of the multiple tact key, other embodiments may be implemented by combining a long press of the reproduction execution key.
