Description

  The present invention relates to an operation signal processing device that executes a function based on an input form of an input operation signal, and a content selection device that selects content recorded on a recording medium.

  When a CD-R (Compact Disc-Recordable) in which a large number of content files such as MP3 files or WMA files are recorded is reproduced by a CD player, the user needs to select a desired content file from the large number of content files. . As methods for selecting a desired content file, the following two methods have been proposed. The first is a method of searching for a desired content file by tracing the directory from the highest root directory to the lower subdirectories. The second is a method in which only the folder in which the content file is recorded is displayed in order on the display unit, and after selecting a desired folder, the content file included in the folder is selected. In order to execute both of these two selection methods on the CD player, it is necessary to provide operation keys corresponding to these two selection methods on the CD player body. However, in consideration of design and cost, the CD player main body cannot be provided with too many operation keys. In addition, in order to perform many other functions, a large number of operation keys are provided in the CD player, and reduction of operation keys is required. For the above reasons, it is not practical to provide the CD player main body with two operation keys for executing the two content file selection methods.

  In addition, two functions can be executed using one operation key by making the functions executed differently when one operation key is pressed long and when it is short pressed (normally pressed). Such a device is described in Patent Document 1 below. However, when a function frequently used by the user is executed by long-pressing the operation key, the user needs to press and hold the operation key every time the function is executed, which makes the operation very complicated. Have. Even if a function frequently used by a user is predicted and the function is assigned to a short press of an operation key, which function is frequently used depends on the user's preference and usage environment, and thus this problem cannot be solved.

  One function determined by the input form of the operation signal (operation mode of the operation unit) and the priority order of the functions is selected and executed from the plurality of functions. Since this priority order is set to be switchable, by setting a high priority order for the frequently used function for each user, the frequently used function can be changed into an operation signal input form (operation part operation form). Of these, the operation unit can be assigned to the simplest operation. As a result, even when a plurality of functions are executed by a single operation unit, the user's operation can be greatly simplified.

  Specifically, the first selection mode and the second selection mode for selecting content are classified into a case where the operation signal input duration is less than a predetermined time (short pressing of the operation unit) and a predetermined time or more. (Long press on the operation unit). In this case, the user sets the priority order so as to give priority to the frequently used one of the two selection modes, so that the frequently used selection mode can be executed by a short press of the operation unit. Can do. Therefore, even when a plurality of selection modes are selectively executed by changing the operation mode of one operation unit, the user's operation can be greatly simplified.

  Hereinafter, an operation signal processing device and a content selection device according to preferred embodiments of the present invention will be described, but the present invention is not limited to these embodiments.

  The operation signal processing apparatus selects and executes one corresponding function from a plurality of functions based on a plurality of operation signal input forms (that is, a plurality of operation modes of an operation unit described later). The input form of the operation signal (the operation mode of the operation unit, specifically, the push-in mode) is a state in which the operation signal input duration is less than a predetermined time (short press of the operation unit), and the operation signal input continues. This means that the time is a predetermined time or longer (long pressing of the operation unit). Alternatively, the input form (operation mode) may be the number of times (one or more times) the operation signal is input (the number of times the operation unit is pushed).

  The operation signal processing apparatus can set the priority order of a plurality of functions (first function and second function) to be switchable. That is, it can be selected (switched) by the user's operation which of the first function and the second function is prioritized. When the input duration of the operation signal is less than the predetermined time (short press of the operation unit), the priority function is executed, and the input duration of the operation signal is longer than the predetermined time (long press of the operation unit) The functions that are not prioritized are executed.

  The content selection device selects one or a plurality of content files from a plurality of content files recorded on the recording medium, and has two selection modes to be described later. By using the operation signal processing device, these two selection modes are selectively executed according to a plurality of operation signal input modes (a plurality of operation modes of the operation unit).

  Hereinafter, the operation signal processing device and the content selection device will be described in detail by taking a disc playback device (for example, a CD player) 10 to which these are applied as an example.

  FIG. 1 is a schematic diagram showing a data structure of a disc (CD-R) played back by the disc playback apparatus 10. The disc includes a lead-in area, a data area, and a lead-out area in order from the inner periphery side. The lead-in area is an area indicating the start of a session, and records track information of tracks included in the data area and TOC (Table Of Contents) information including the length (time) of the data area. The data area is an area for recording file names of content files (for example, music files, video files or image files) and content files. The lead-out area is an area indicating the end of the session.

  The content file and its file name are recorded in the data area by a hierarchical directory structure. The hierarchical directory structure includes a root directory RD that is the highest directory and a plurality of subdirectories SD1 to SD5 that are created under the root directory RD. In FIG. 1, the subdirectory SD1 includes lower subdirectories SD4 and SD5, the subdirectory SD4 includes content files A to C, and the subdirectory SD5 includes content files D to F. The file name of the content file is recorded in the immediately preceding (immediately higher) subdirectory. The directory name of the subdirectory is recorded in the subdirectory or root directory immediately before (immediately above).

  FIG. 2 is a schematic block diagram showing the configuration of the disc playback apparatus 10. The disc playback apparatus 10 includes a system control unit 11, a display unit 12, an operation unit 13, a playback operation drive unit 14, a signal processing circuit 15, and a D / A converter 16.

  The system control unit 11 outputs a command to each unit of the disc playback apparatus 10 to control each unit, and includes a CPU 11a, a ROM 11b, and a RAM 11c.

  The CPU 11a reads various programs stored in the ROM 11b based on operation signals input from the operation unit 13, expands them in the work memory of the RAM 11c, and executes various processes according to the programs.

  The CPU 11a selectively executes a plurality of functions based on the input form of the operation signal input from the operation unit 13. In other words, the CPU 11 a selectively executes a plurality of functions based on the operation mode of the operation unit 13. That is, even if the same operation signal is input (even if the same operation unit 13 is operated), the CPU 11a performs different functions depending on the input form of the operation signal (operation mode of the operation unit 13). For example, the input form includes a state in which the input of the operation signal is completed within a predetermined time after the operation signal is input (short press of the operation unit 13), and the input of the operation signal for a predetermined time or more after the input of the operation signal. Is a state in which the operation continues (long pressing of the operation unit 13). When the operation signal is input, the CPU 11a starts a timer count, determines whether the input of the operation signal continues for a predetermined time or more, and determines a function to be executed. The operation signal means that the voltage value of the voltage input to the CPU 11a changes when the operation unit 13 is pushed, for example. The operation signal may be a remote control signal (a constant pulse signal) input from the outside.

  As a function to be executed, a transition to the first selection mode or the second selection mode for selecting one or a plurality of content files from a plurality of content files recorded on the recording medium (the operation state of the CPU 11a). Transition). The first selection mode is a mode in which a directory is sequentially traced from the highest root directory RD to the subdirectory SD and a desired content file is selected (hereinafter referred to as NAVI (navigation) mode). The second selection mode is a mode in which only folders in which content files are recorded are displayed in order on the display unit 12 and a desired folder is selected, and then a content file included in the folder is selected (hereinafter referred to as a folder). Mode).

  FIG. 3 is a diagram for explaining the transition of the display screen of the display unit 12 when a content file is selected in the NAVI mode in the case of the directory structure of FIG. When the NAVI mode is selected, the root directory RD is displayed on the display unit 12 as shown in FIG. When a determination signal is input in this state, the process proceeds to (b), and the subdirectory SD1 (or directory name, the same applies hereinafter), SD2, and SD3 are selectively displayed (in order) by the selection signal on the display unit 12. . When the determination signal is input while the subdirectory SD1 is displayed, the process proceeds to (c), and the lower subdirectories SD4 and SD5 are selectively displayed by the selection signal. When the determination signal is input while the subdirectory SD4 is displayed, the process proceeds to (d), and the content files A to C are selectively displayed by the selection signal. When the determination signal is input while the subdirectory SD5 is displayed, the process proceeds to (e), and the content files D to F are selectively displayed by the selection signal. When the determination signal is input while the subdirectory SD2 is displayed, the process proceeds to (f), and the content files G to I are selectively displayed by the selection signal. When the determination signal is input while the content files A to I are displayed, the displayed content file is selected and the content file is reproduced.

  FIG. 4 is a diagram for explaining the transition of the display screen of the display unit 12 when a content file is selected in the folder mode in the case of the directory structure of FIG. When the folder mode is selected, the display unit 12 selectively displays subdirectories SD4 (or directory names, the same applies hereinafter), SD5, and SD2 in which content files are recorded as shown in FIG. Is displayed. When the determination signal is input while the subdirectory SD4 is displayed, the process proceeds to (b), and the content files A to C are selectively displayed by the selection signal. When the determination signal is input while the subdirectory SD5 is displayed, the process proceeds to (c), and the content files D to F are selectively displayed by the selection signal. When the determination signal is input while the subdirectory SD2 is displayed, the process proceeds to (d), and the content files G to I are selectively displayed by the selection signal. When the determination signal is input while the content files A to I are displayed, the displayed content file is selected and the content file is reproduced.

  When the operation signal is input, the CPU 11a determines which of the selection modes is to be changed based on the input form of the operation signal and the priority of the selection mode. The priority order indicates which of the NAVI mode and the folder mode is to be changed when the input of the operation signal is finished within a predetermined time (short press of the operation unit 13). It can be set by the user. That is, when the NAVI mode is prioritized, a short press of the operation unit 13 makes a transition to the NAVI mode, and a long press makes a transition to the folder mode. On the other hand, when the folder mode is prioritized, a short press of the operation unit 13 makes a transition to the folder mode, and a long press makes a transition to the NAVI mode.

The RAM 11c stores priority flags shown in Table 1 below. For example, when the priority flag is set to 1, the NAVI mode is prioritized, and when the priority flag is reset to 0, the folder mode is prioritized.

  The ROM 11b stores an operation program and the like of the disk playback device 10. The ROM 11b is composed of a magnetic or optical recording medium or a nonvolatile memory such as a semiconductor.

  The display unit 12 is configured by an LCD (Liquid Crystal Display) or the like, and displays a content file selection screen (FIGS. 3 and 4). That is, the display unit 12a displays the file name and / or directory name of the content file based on the command and character information input from the CPU 11a.

  The operation unit 13 includes various function keys such as a content selection key, a reproduction key, a numeric keypad, a SKIP UP / DOWN key, a stop key, and an EJECT key, and outputs operation signals generated by key operations to the system control unit 11. The content selection key is a key that can be rotated and pushed, and outputs a selection signal to the system control unit 11 by a rotation operation and a determination signal to the system control unit 11 by a push operation. Also, whether the transition to the NAVI mode or the folder mode is made is determined by short pressing or long pressing of the content selection key. Further, the operation unit 13 may output an operation signal by remote control to the system control unit 11.

  The reproduction operation drive unit 14 reads out the file name recorded in the subdirectory and outputs it to the system control unit 11. The reproduction operation drive unit 14 also reads out the content file recorded in the subdirectory and outputs it to the signal processing circuit 15. The reproduction operation drive unit 14 includes an optical pickup 14a and a servo circuit 14b. The reproduction operation drive unit 14 searches for a target address on the disk by a command input from the system control unit 11 and reproduces data corresponding to the address. The optical pickup 14a moves in the radial direction of the disk by a thread controlled by the servo circuit 14b, irradiates the disk with laser light, and converts the reflected light into an electrical signal, thereby recording data recorded on the disk. Read.

  The signal processing circuit 15 is configured by a DSP (Digital Signal Processor) or the like, and executes decoding processing on content file data read by the optical pickup 14a. Specifically, a decoding method (EFM decoding / AAC decoding / MP3 decoding, etc.) corresponding to the content file for each session is set by the CPU 11a, and decoding processing of the decoding method is executed.

  The D / A converter 16 converts the content data processed by the signal processing circuit 15 into an analog signal. The output of the D / A converter 16 is supplied to an amplifier device and a speaker connected to the outside via a sound output terminal (not shown) and reproduced as sound.

  The content file selection operation of the disc playback apparatus 10 having the above configuration will be described with reference to FIGS.

  First, with reference to FIG. 5, an operation for selecting the priority order between the NAVI mode and the folder mode based on a user operation will be described. The CPU 11a determines whether or not an operation signal for starting to set priority is input (S1). When an operation signal for starting priority setting from the operation unit 13 is input to the system control unit 11 (S1: YES), the CPU 11a causes the display unit 12 to display a setting screen for setting the priority.

  Specifically, as shown in FIG. 6, since the NAVI mode and the folder mode are selectively displayed on the display unit 12 by the selection signal, the desired selection mode is displayed on the display unit 12. The determination signal is input to the system control unit 11 by a user operation.

  When the determination signal is input while the NAVI mode is displayed, the CPU 11a determines that the NAVI mode is prioritized (S2: YES), and sets the priority order to the NAVI mode (S3). That is, the priority flag in the RAM 11c is set to 1. On the other hand, when the determination signal is input in a state where the folder mode is displayed, the CPU 11a determines that the folder mode has priority (S2: NO), and sets the priority order to the folder mode. That is, the priority flag in the RAM 11c is reset to zero.

  Next, the content file selection operation will be described with reference to FIG. The CPU 11a determines whether or not an operation signal has been input (S5). When the content selection key is pressed by the user, an operation signal is output from the operation unit 13 to the system control unit 11. At this time, the CPU 11a determines that an operation signal has been input (S5: YES), and starts a timer count in the RAM 11c (S6).

  Next, the CPU 11a checks the priority flag in the RAM 11c and determines whether or not the NAVI mode is prioritized (the priority flag is 1) (S7). When the NAVI mode is prioritized (priority flag is 1) (S7: YES), the CPU 11a transitions to the NAVI mode as the selection mode (S8). That is, the CPU 11a causes the user to select a content file by causing the display unit 12 to display the selection screen illustrated in FIG.

  On the other hand, when the folder mode is prioritized (priority flag is 0) (S7: NO), the CPU 11a transitions to the folder mode as the selection mode (S9). That is, the CPU 11a causes the user to select a content file by causing the display unit 12 to display the selection screen illustrated in FIG.

  Next, the CPU 11a determines whether or not the operation signal is continuously input (S10). If the content selection key is kept pressed, an operation signal is continuously input (S10: YES), so the CPU 11a counts up the timer count in the RAM 11c (S11), and whether the time counted by the timer has reached a predetermined time? It is determined whether or not (S12). The predetermined time is a time determined to be a long press of the content selection key, and is, for example, 2 seconds. That is, when the operation signal is continuously input, the processes of S10 to S12 are repeated until the time measured by the timer reaches a predetermined time in S12.

  When the time measured by the timer reaches a predetermined time in S12, the CPU 11a determines that the operation signal has been continuously input for a predetermined time or longer (the content selection key has been pressed for a long time), and proceeds to S13, where S8, S9 Transition to a selection mode different from the selection mode transitioned in. That is, the CPU 11a checks the priority flag in the RAM 11c and determines again whether or not the NAVI mode is prioritized (priority flag is 1) (S13). If the NAVI mode is prioritized (priority flag is 1) (S13: YES), the CPU 11a transitions to the folder mode as the selection mode (S14). That is, the CPU 11a causes the user to select a content file by causing the display unit 12 to display the selection screen illustrated in FIG.

  On the other hand, when the folder mode is prioritized (priority flag is 0) (S13: NO), the CPU 11a transitions to the NAVI mode as the selection mode (S15). That is, the CPU 11a causes the user to select a content file by causing the display unit 12 to display the selection screen illustrated in FIG.

  On the other hand, if it is determined in S12 that the operation signal has not been input before the time counted by the timer reaches the predetermined time, the CPU 11a finishes input of the operation signal in less than the predetermined time (the content selection key is It is determined that the button has been pressed for a short time, and the process ends with the selection mode changed in S8 or S9.

  As a result of the above processing, when the NAVI mode is prioritized, the content selection key is changed to the NAVI mode when pressed for a short time, and the folder mode is changed when pressed for a long time. When the folder mode is prioritized, the mode changes to the folder mode when the content selection key is pressed for a short time, and shifts to the NAVI mode when the content selection key is pressed for a long time. Therefore, the user can execute the selection mode with the high use frequency by short pressing the content selection key by setting the priority order so that the selection mode with the high use frequency (favorite) is given priority. It can be greatly simplified.

  Note that, among the NAVI mode and the folder mode, the one with the higher number of use by the user can be automatically given priority. FIG. 8 is a flowchart for explaining this process. The same processes as those in FIG. In this process, the priority order setting process of FIG. 5 is not required.

Instead of the priority flag, the RAM 11c stores a counter indicating the number of times of final transition to the NAVI mode and the folder mode as shown in Table 2 below. That is, in this example, a selection mode with a large number of final transitions is automatically given priority. Here, the final number of transitions means that when the content selection key is pressed for a long time and the selection mode is determined in S15 or S16, the selection mode once transitioned in S8 or S9 is not counted. . Although not particularly limited, the number of NAVI modes is set to 1 in the initial state, and the number of times of the folder mode is set to 0. The number of times of NAVI mode is increased by adding 2 for each transition. And the number of times of the folder mode can be prevented from being the same.

  In S17, the CPU 11a refers to the counter in Table 2 to determine whether the NAVI mode has more transitions than the folder mode. When the number of transitions is greater in the NAVI mode (S17: YES), the CPU 11a transitions to the NAVI mode, and when the number of transitions is greater in the folder mode (S17: NO), the CPU 11a transitions to the folder mode.

  Similarly, in S23, the CPU 11a refers to the counter in Table 2 to determine whether the NAVI mode has more transition times than the folder mode. When the number of transitions is greater in the NAVI mode (S23: YES), the CPU 11a transitions to the folder mode, and when the number of transitions is greater in the folder mode (S23: NO), the CPU 11a transitions to the NAVI mode.

  In S30, in the counter of Table 2, the number of times of the selection mode finally transitioned is increased by 2, and the process is terminated.

  With the above processing, it is not necessary for the user to set a priority selection mode, and a selection mode frequently used by the user can be automatically executed by a short press of the content selection key.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. The input form of the operation signal is not limited to the time when the operation signal is input, but may be the number of times the operation signal is input. In this case, the user's operation corresponds to the number of times the content selection key has been pressed (whether the key has been pressed once or twice). Moreover, the function performed based on the input form of the operation signal is not limited to two, and may be three, for example. In other words, when the input of the operation signal does not continue for the first predetermined time, when the operation signal continues for the first predetermined time or longer, or when the operation signal continues for the second predetermined time (longer than the first predetermined time), the different functions May be executed. In this case, the priority order (first to third) of these functions is set in the RAM 11c. In addition, when the operation unit 13 can be pushed and rotated, the priority order of pushing and rotating may be changed to replace the functions assigned to each.

  The present invention can be suitably employed in any disc playback apparatus that needs to select content.
