Description

  The present invention relates to a content selection device and a program thereof.

  2. Description of the Related Art A playback device that records content such as a music file on a storage medium such as an HDD, reads the content from the HDD, and plays it back is used. When the user operates the playback device and selects a desired content to be played back from among a plurality of contents recorded on the HDD, a song list is displayed on the display unit of the playback device. The song list is a list of song names of a plurality of song files, and is generated by acquiring content information from the content information DB recorded in the HDD. When a user operation causes a cursor to be displayed at a desired song name in the song list and a playback instruction is input, the song file on which the cursor is displayed is read from the HDD and played back. When the screen size of the display unit of the playback device is small, only a few song names can be displayed at a time in the song list displayed on the display unit.

  A jog dial is used to move the cursor in the song list. The display position of the cursor can be moved to the next content by rotating the jog dial, and the content on which the cursor is displayed can be determined by pushing the jog dial. However, when an enormous number of contents are recorded on the HDD, the cursor cannot be displayed on the content desired by the user unless the jog dial is rotated many times.

JP 2003-100065 A

  The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide a content selection device that can quickly select desired content.

  A content selection device according to a preferred embodiment of the present invention includes a first operation unit that accepts a rotation operation by a user operation, and, in the normal mode, when the first operation unit is rotated, In the content skip mode, in the content skip mode, when the first operation means is rotated, a means for skipping the selected content to two or more contents ahead, and a user operation, the first operation means Means for determining whether a series of continuous rotation operations have been executed; means for counting the number of series of continuous rotation operations of the first operation means; and the number of series of continuous rotation operations of the first operation means. It is determined that the means for determining whether or not it is greater than or equal to a predetermined value and the number of successive rotation operations of the first operating means are greater than or equal to a predetermined value. If the, and means for transition from the normal mode to the content skip mode.

  If the number of continuous rotation operations of the first operation means continues for a predetermined value or more, it is considered that the user desires to select content far ahead. Therefore, when the number of series of continuous rotation operations of the first operation means continues for a predetermined value or more, the mode shifts from the normal mode to the content skip mode. In the content skip mode, when the first operation means is rotated, the selected content is skipped to two or more content ahead. Therefore, desired content can be selected quickly.

  In a preferred embodiment, in the content skip mode, the content selection device displays on the display device the number of content items to be skipped, information on the currently selected content, and information on the content selected after being skipped. And a second operation means for accepting a push operation by a user operation, and when the second operation means is pushed in the content skip mode, the content selection mode is changed from the content skip mode to the current mode displayed. And a means for displaying a content list including information on the content being recorded.

  In the content skip mode, the number of contents to be skipped, information on the currently selected content, and information on the content selected after skipping are displayed. Therefore, the user can easily determine whether to further rotate the first operation means in the content skip mode or push the second operation means to shift to the normal mode by checking the display contents. can do.

  In a preferred embodiment, the content selection device determines whether or not the elapsed time from the end time of a series of continuous rotation operations of the first operation means to the next rotation operation of the first operation means is a predetermined time or more. If it is determined that the elapsed time from the end time of the series of continuous rotation operations of the first operation means to the rotation operation of the next first operation means is a predetermined time or more, And a means for initializing a count of a series of continuous operation times of the first operation means to zero.

  If the elapsed time from the end time of the series of continuous rotation operations of the first operation means to the rotation operation of the next first operation means is a predetermined time or more, the user desires to select a considerably earlier content. I can't think of it. Therefore, in such a case, the transition from the normal mode to the content skip mode against the user's intention can be prevented by initializing the count of the number of consecutive operations of the first operation means to 0. it can.

  In a preferred embodiment, the content selection device further includes means for increasing or decreasing the number of contents to be skipped in the content skip mode based on the number of rotation operations of the first operation means in the content skip mode.

  For example, if the number of contents to be skipped is increased as the number of rotation operations of the first operation means in the content skip mode is increased, the contents can be skipped quickly even when the number of contents is enormous.

  A content selection program according to a preferred embodiment of the present invention causes a computer to execute each means of any of the above content selection devices.

  Therefore, it can be provided in the form of a content selection program.

  It is possible to provide a content selection device that can quickly select desired content.

It is a figure which shows the transition of the display content in content skip mode and normal mode. 3 is a flowchart showing processing of a control unit 2. 3 is a flowchart showing processing of a control unit 2. It is a figure which shows the transition of the display content in content skip mode. 3 is a flowchart showing processing of a control unit 2.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings. However, the present invention is not limited to these embodiments. FIG. 1 is a block diagram showing a playback apparatus 1 to which a content selection apparatus according to a preferred embodiment of the present invention is applied.

  The playback device 1 records a plurality of contents in a storage medium such as an HDD (hard disk drive) or a flash memory. Content is a general term for music data (music file), video data, image data, and the like. In this example, a case of a music file will be described as an example. The playback device 1 reads out desired content from the HDD and plays it back. The playback device 1 acquires content information of a plurality of contents from the HDD, and displays a content list (hereinafter referred to as a song list) in which the content information is listed. If the content is a song file, the content information is metadata such as the song name (title), artist name, album name, genre name, author, and release year of the song file. In this example, the content information is described as an example. To do.

  The playback device 1 includes a control unit 2, a memory (ROM, RAM, etc.) 3, a storage medium 4 such as an HDD or a flash memory, an image processing unit 5, a playback unit 6, an amplification unit 7, and an operation unit 8. And a display unit 9. The control unit 2 reads out the content selection program stored in the memory (ROM) 3 or the HDD 4 to the RAM and executes it, thereby executing each process of the flowchart described later, for example, a microcomputer or a CPU. .

  The HDD 4 stores a plurality of music files and a content information database (hereinafter referred to as a content information DB). The content information DB is a database for storing and managing content information (song name, artist name, album name, etc.) related to all song files recorded in the HDD 4. For example, song names of song files are rearranged in alphabetical order and / or alphabetical order, and song numbers are assigned in that order.

  The control unit 2 acquires content information from the content information DB, causes the image processing unit 5 to generate a song list, and causes the display unit 9 to display the song list. The song list includes a predetermined number of song names that can be displayed on the display unit 9 among the song names of a plurality of song files recorded in the HDD 4.

  The operation unit 8 receives user operations. The operation unit 8 includes first operation means for inputting a rotation operation by the user and second operation means for inputting a push operation by the user. In the present embodiment, a jog dial that functions as both the first operating means and the second operating means may be employed. Note that the rotation operation includes the meaning of counterclockwise rotation in addition to clockwise rotation.

  There are a content skip mode and a normal mode as modes for selecting a song title.

  The content skip mode is a mode in which, when the first operation means is rotated, the selected content is skipped to two or more content ahead. As shown in FIGS. 2A to 2C, in the content skip mode, the number of songs to be skipped (for example, 100 songs), information on the content that is currently displayed with the cursor displayed (song title), and skip The cursor will be displayed after selecting the song name and the song name to be selected. For example, in FIG. 2A, when the jog dial is rotated once (one step) by a user operation, 100 songs are skipped from the currently selected song name “CCCC” and the song name “FFFF” is selected. It is shown that. When the jog dial is rotated once by a user operation in the state of FIG. 2A, the state transitions to the state of FIG. FIG. 2B shows that when the jog dial is rotated once by a user operation, 100 songs are skipped from the currently selected song name “FFFF” and the song name “JJJJ” is selected.

  The normal mode is a mode in which the selected content is advanced to the next content when the first operation means is rotated by a user operation. When the second operation means is pushed in the content skip mode, the content skip mode is shifted to the normal mode. For example, when the jog dial is pushed by a user operation in the state of FIG. 2A, a song list starting from the currently selected song name “CCCC” is displayed as shown in FIG. ”Is displayed on the cursor. In the normal mode, when the jog dial is rotated once (one step) by a user operation, the display position of the cursor is moved to the next song name, and the next song name is selected. For example, in the state shown in FIG. 2D, when the jog dial is rotated once by a user operation, the song title “CCCD” is selected.

  When the operation such that the jog dial is continuously rotated by a user operation, the user operation is stopped for a short time, and then the jog dial is continuously rotated again is continued, the control unit 2 has a huge number of users. Judging that you want to scroll the song. Therefore, in such a case, the normal mode is shifted to the content skip mode. That is, the control unit 2 determines whether or not a series of continuous rotation operations of the first operation means has been executed by a user operation, and counts the number of series of continuous rotation operations of the first operation means. For example, it is recognized as a series of continuous rotation operations when the first operation means is continuously rotated in the same direction five or more times. And the control part 2 judges whether the frequency | count of a series of continuous rotation operation of a 1st operation means is more than predetermined value, and the frequency | count of a series of continuous rotation operation of a 1st operation means is more than predetermined value. If it is determined, the mode is shifted from the normal mode to the content skip mode.

  Returning to FIG. 1, the image processing unit 5 generates a display screen in the content skip mode or a display screen in the normal mode in accordance with an instruction from the control unit 2, and causes the display unit 9 to display the display screen. The playback unit 6 reads the music file selected by the user operation from the HDD 4 and executes playback processing (including decompression processing, D / A conversion processing, equalizer processing, etc.) on the read music file. The amplifying unit 7 amplifies the audio signal reproduced by the reproducing unit 6 and supplies the audio signal to a speaker (not shown).

  As described above, the display unit 9 displays a display screen in the content skip mode or a display screen in the normal mode, and an arbitrary one such as an LCD (liquid crystal display), an organic EL display, or an FL tube is adopted. obtain. The display unit 9 may be an OSD (on-screen display) generation unit for displaying a music list on a display device such as a TV receiver connected to the outside of the playback device 1.

  The operation of the playback apparatus 1 having the above configuration will be described. 3 and 4 are flowcharts showing processing of the control unit 2 in the present embodiment. FIG. 3 shows a process when shifting from the normal mode to the content skip mode. As shown in FIG. 3, the control unit 2 initializes the number RCnt of a series of continuous rotation operations of the jog dial to 0 (S1). The control unit 2 initializes the total number of rotation operations Cnt to be regarded as a series of continuous rotation operations of the jog dial to 0 (S2).

  The control unit 2 determines whether or not the jog dial has been rotated by a user operation (S3). If it is determined that the jog dial has been rotated (YES in S3), the control unit 2 determines whether Rcnt is 1 or more and the time obtained by subtracting the time t1 from the current time is greater than or equal to a predetermined threshold value. Judgment is made (S4). Here, the time t1 is the time stored in S14 described later. Here, since it is determined NO in S4, the control unit 2 adds 1 to the value of Cnt (increments) (S5). The situation where YES is determined in S4 will be described later.

  Subsequently, the control unit 2 determines whether or not the jog dial is further rotated by a user operation (S6). When the jog dial is rotated (YES in S6), the control unit 2 determines that the current jog dial rotation operation is in the same direction as the previous jog dial rotation operation, and that the current jog dial rotation operation is performed from the previous jog dial rotation operation. It is determined whether the elapsed time (operation interval) until the rotation operation is equal to or less than a predetermined value RT (S7). That is, it is determined whether or not the current rotation operation of the jog dial can be regarded as one operation of a series of continuous rotation operations of the jog dial. Note that the time and direction of the previous rotation operation of the jog dial are stored in the memory by the control unit 2.

  If NO is determined in S7, that is, (1) the current jog dial rotation operation is in the opposite direction to the previous jog dial rotation operation, or (2) the current jog dial rotation operation from the previous jog dial rotation operation. When the elapsed time (operation interval) until the rotation operation is longer than the predetermined value RT, the process returns to S1, and RCnt and Cnt are initialized to 0. In such a case, it is considered that it is not a series of continuous rotation operations of the jog dial, and it is not necessary to shift to the content skip mode.

  When it is determined YES in S7, the control unit 2 adds 1 (increments) the value of Cnt (S8). Subsequently, the control unit 2 determines whether or not Cnt is equal to or greater than a predetermined value N (S9). The predetermined value N is the number of rotation operations that can be regarded as a series of continuous rotation operations of the jog dial, and is, for example, 5. That is, it is determined whether or not the jog dial has been rotated in the same direction five times (five steps). If it is determined that Cnt is less than N (NO in S9), the process returns to S6.

  If it is determined that Cnt is greater than or equal to N (YES in S9), the control unit 2 adds 1 to the value of Rcnt (increments) (S10). That is, it is determined that a series of continuous rotation operations of the jog dial has been executed, and the number of continuous rotation operations of the jog dial is added once. Subsequently, the control unit 2 determines whether or not RCnt is equal to or greater than a predetermined value M (S11). The predetermined value M is the number of continuous rotation operations of the jog dial for determining that the content skip mode should be shifted, and is 3, for example.

  When RCnt is less than the predetermined value M (NO in S11), the control unit 2 determines whether or not the jog dial rotation operation has been executed for a certain period of time from the previous operation by the user operation (S13). When the rotation operation of the jog dial is further executed (NO in S13), the control unit 2 stands by without proceeding with the process. This is because the number of jog dial rotation operations has already reached the number of times recognized as a series of continuous rotation operations of the jog dial (YES in S9), but the jog dial rotation operation is continued by the user operation. This is because the rotation operation is excluded from the count of Cnt and RCnt. That is, when the jog dial is continuously rotated in the same direction for 5 steps, it is already recognized as a series of continuous rotation operations of the jog dial. For example, the jog dial is continuously rotated in the same direction for 8 steps. Even so, it is determined that the jog dial has the same series of continuous rotation operations.

  If YES is determined in S13, that is, if the user once stops the rotation operation of the jog dial after a series of continuous rotation operations of the jog dial, the control unit 2 stores the time t1 at that time in the memory (S14). Thereafter, the process returns to S2 to initialize Cnt to 0.

  On the other hand, when it is determined in S11 that RCnt is equal to or greater than the predetermined value M (YES in S11), the control unit 2 shifts from the normal mode to the content skip mode (S12). That is, since a series of continuous rotation operations of the jog dial has continued M times, it can be determined that the user desires to select a song name considerably ahead, and the mode shifts from the normal mode to the content skip mode.

  Here, the case where YES is determined in S4 will be described. Since RCnt is 1 or more, a series of continuous rotation operations of the jog dial are executed at least once. If the current time-time t1, that is, the elapsed time (operation interval) from the end of a series of continuous rotation operations of the previous jog dial is equal to or greater than a threshold (for example, 1 second), the user selects a song name that is considerably ahead Since it cannot be determined that it is desired to do so, the process returns to S1 without shifting to the content skip mode, and RCnt and Cnt are initialized to 0.

  FIG. 4 shows processing of the control unit 2 in the content skip mode. The control unit 2 stores the currently selected song name in the memory and displays it (S21). For example, as shown in FIG. 2A, “CCCC” is displayed as the currently selected song name. The control unit 2 displays the number of skipped music titles by the next jog dial rotation operation (S22). For example, as shown in FIG. 2A, 100 is displayed as the skip number. Furthermore, when the music title is skipped by the number of skips displayed, the control unit 2 specifies the music title to be selected and displays the specified music title (S23). For example, as shown in FIG. 2A, it is displayed that the song name “FFFF” is selected when the currently skipped song name “CCCC” is skipped by the number of displayed skips (100 songs). The

  Subsequently, the control unit 2 determines whether or not a jog dial rotation operation has been executed by a user operation (S24). When the rotation operation of the jog dial is executed (YES in S24), the control unit 2 skips the selected song name for the displayed skip number and newly selects the song name (S25). And a process returns to S21 and a new display is performed. For example, in FIG. 2A, when the jog dial is rotated, the currently selected song name “CCCC” is skipped by the number of displayed skips (100 songs) and the song name “FFFF” is selected. Is done.

  As a result, “FFFF” is displayed as the currently selected song name as shown in FIG. It is also displayed that if the skipped number (100 songs) of the currently selected song name “FFFF” is skipped, the song name “JJJJ” is selected.

  When it is determined that the jog dial rotation operation is not executed (NO in S24), the control unit 2 determines whether or not the jog dial push operation by the user operation is executed (S26). If it is determined that the jog dial push operation is not executed (NO in S26), the process returns to S24. When it is determined that the jog dial push operation has been executed (YES in S26), the control unit 2 shifts from the content skip mode to the normal mode and displays the song list (S27). At this time, a cursor is displayed on the selected song name. For example, when a jog dial push operation is executed in the state of FIG. 2B, a song list with a cursor displayed on the selected song name “FFFF” is displayed as shown in FIG. 2E. The Although the selected song name is displayed at the top of the song list, the present invention is not limited to this, and the selected song name may be displayed at another location (for example, the center) of the song list.

  In the example of FIG. 2, in the content skip mode, the skip number is fixed to 100 songs, but the skip number may be increased or decreased each time the jog dial is rotated. For example, the number of skips of the song title is set in advance according to the number of rotations of the jog dial in the content skip mode. As shown in FIG. 5, the number of skips displayed in FIG. As the number of skips displayed in b) is 500 and the number of skips displayed in FIG. 5C is 1000, the number of skips is increased each time the jog dial is rotated.

  FIG. 6 is a flowchart showing processing of the control unit 2 in the present embodiment. The same processes as those in FIG. The control unit 2 initializes the number of rotations of the jog dial in the content skip mode to 0 (S31). The control unit 2 stores the currently selected song name in the memory and displays it (S21). For example, as shown in FIG. 5A, “CCCC” is displayed as the currently selected song name.

  The control unit 2 specifies the number of skips corresponding to the number of rotation operations of the next jog dial, and displays the specified number of skips (S32). For example, since the number of rotation operations of the next jog dial is the first time, 100 is specified as the number of skips corresponding to the first time, and 100 is displayed as the number of skips as shown in FIG. Furthermore, when the music title is skipped by the number of skips displayed, the control unit 2 specifies the music title to be selected and displays the specified music title (S23). For example, as shown in FIG. 5A, it is displayed that the song name “FFFF” is selected when the currently skipped song name “CCCC” is skipped by the number of displayed skips (100 songs). The

  Subsequently, the control unit 2 determines whether or not a jog dial rotation operation has been executed by a user operation (S24). When the rotation operation of the jog dial is executed (YES in S24), the control unit 2 skips the selected song name for the displayed skip number and newly selects the song name (S25). The control unit 2 adds 1 to (increments) the number of rotations of the jog dial (S33).

  And a process returns to S21 and a new display is performed. For example, in FIG. 5A, when a jog dial rotation operation is executed, the number of displayed skips (100 songs) is skipped from the currently selected song name “CCCC”, and the song name “FFFF” is selected. Is done.

  As a result, as shown in FIG. 5B, “FFFF” is displayed as the name of the currently selected song. Further, since the next jog dial rotation operation is the second time, 500 is specified as the number of skips corresponding to the second time, and 500 is displayed as the number of skips as shown in FIG. Further, it is displayed that when the skipped number (500 songs) of the currently selected song name “FFFF” is skipped, the song name “JJJJ” is selected.

  In addition to the number of jog dial rotation operations in the content skip mode, the number of skips may be changed according to the number of remaining contents that can be skipped in the song list. For example, if the number of operations of rotating the jog dial in the content skip mode is large, but the number of remaining contents that can be skipped in the song list is small, the number of skips may be reduced.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. In the present embodiment, the jog dial capable of both the rotation operation and the push operation is adopted. However, the present invention is not limited to this. The first operation means capable of the rotation operation and the second operation capable of the push operation. The means may be provided separately. The present invention can also be applied to a client device (playback device), a controller, or the like that can be connected to a server that stores content and a content information DB via a network. That is, it is not necessary for the content selection device of the present invention itself to store the content and the content information DB, and the content selection device of the present invention does not have to have a function of reproducing the content. That is, the content selection device of the present invention only needs to have a function of selecting content. The present invention may be provided in the form of a computer program for operating the content selection device, a recording medium recording the computer program, or a content information display method.

  The present invention can be suitably applied to a playback apparatus.
