Description

  The present invention relates to a content playback apparatus that plays back content such as video and audio, and a content information scrolling display method for selecting content such as video and audio. In particular, the present invention relates to a portable digital audio player and the like. The present invention relates to a content reproduction apparatus and a content information scroll display method.

  In recent years, with the development of audio compression techniques represented by MP3 and AAC, music can be handled as high-quality digital data even with a small amount of data. In addition, due to the increase in capacity of recording media such as hard disks and flash memories, it is possible to have a large capacity even with small, randomly accessible recording media, and these recording media can be used as recording media for recording music as digital data. Recording media have come to be used. Under such circumstances, a portable digital audio player equipped with a small hard disk or flash memory as a recording medium is rapidly spreading due to the convenience of being able to carry a large number of music pieces without changing them.

  These portable digital audio players can record thousands of songs on a recording medium having a recording capacity of several gigabytes. Hierarchical music information such as genre name, artist name, album name, title name, and the like is added to the music, and the user can select the music by using the music information as a clue.

  For example, when selecting a music piece from the title name, the title name is displayed in a list format in the sorted order on the display of the digital audio player. At the same time, several title names are displayed on the display in one line for each title name. The user scrolls the title name until the title name of the desired song is displayed on the display, and after the title name of the desired song is displayed on the display, the user selects one of the displayed title names. The title name is selected with a pointer or the like. Thus, for example, if the title name of the desired song is 500th in the sorted order, scrolling for about 500 lines while sequentially checking whether the title name of the desired song is displayed. There is a need.

  At this time, it is desirable for the user that the title name of the desired music can be selected in a short time. Normally, the scroll speed can be changed according to the user's operation. Therefore, until the title name of the desired music is displayed, it is attempted to scroll as fast as possible. However, as the scroll speed increases, it becomes more difficult to read the displayed title name. For this reason, the scrolling speed cannot be increased to a certain degree in order to sequentially check whether the title name of the desired music is displayed.

  Conventionally, as this type of content playback apparatus and content information scroll display method, for example, there is a method described in Patent Document 1.

  In Patent Document 1, music information such as the artist name, album name, and title name of music is sorted and divided into a plurality of groups for each initial letter. When changing, that is, for example, when the initial of the title name changes from “A” to “I” in the display of the title name, updating of the display screen is stopped for a predetermined time.

In this way, even if scrolling is performed so fast that the displayed title name cannot be read, the display screen stops and the title name can be read reliably when the initial character changes, so that the user can By comparing with the initials of the title names of the music pieces, it is possible to check each time how much the scroll is advanced with respect to the title name of the desired music piece. Therefore, it is possible to shorten the time until the title name of the desired music is selected.
JP 2005-4891 A

  However, in the conventional configuration, it cannot be said that the time until the title name of a desired music is selected can be shortened sufficiently.

  In the conventional configuration, the scrolling is stopped for a predetermined time each time the initial of the title name changes. For example, if the title name of the desired song starts with “Wa”, the title name is close to the end of the initial order, and the kana characters start with “A”, “I”, “U”, …, “Re”, “Ro”, “Wa”, and the title of the group whose initials are “Wa”. Even so, the total stop time will be too long to ignore. In addition, for example, even if the title name of the desired song starts with “I” and is a title name that is close to the beginning of the order of the initials, there is no change in the scroll stop time itself. Therefore, the time until the title name of the desired music is selected becomes longer by the amount of the stop time.

  Further, in the conventional configuration, the scrolling is stopped only when the initial letter of the title name changes. For example, when the number of music pieces recorded on the recording medium is thousands, if there are 26 alphabetic characters and 46 kana characters, there will be an average of several tens of music per initial. Since the distribution of the initials of actual title names is biased, there are more songs depending on the initials. Therefore, even if you can scroll at high speed until you reach a group that matches the initials, within the same initial group, dozens of title names are slow enough to read the title name. Scrolling will increase the time required to select the title name of the desired song.

  In order to solve the above problems, the present invention updates and displays the content information such as the title name of a piece of music in the first area on the display screen of the display unit each time it is scrolled. In the second area on the display screen, the content information is updated and displayed every time a plurality of contents information are scrolled. As a result, even if the scrolling of the content information is not stopped halfway and the number of contents such as music is large, it is possible to shorten the time until the content information of the desired content is selected. In addition, it is possible to provide a content playback apparatus and a scroll display method for content information.

  In order to solve the above-described conventional problem, the content reproduction apparatus of the present invention includes a display unit on which content information for selecting content is displayed on a display screen, an operation unit for instructing scrolling of the content information, A content playback apparatus including a control unit, wherein the display screen of the display unit includes at least a first area and a second area, and displays the content information in a list format. When the content information is scrolled and sequentially displayed on the display screen according to an instruction from the operation unit, the content information is updated and displayed each time one content is scrolled in the first area. In the second area, the content information in the first area is controlled to be updated and displayed every time a plurality of scrolls are performed.

  The content information scroll display method of the present invention includes a display step of displaying content information for selecting content in a list form on a display screen of a display unit, an operation step of instructing scrolling of the content information, A content information scroll display method comprising: a control step for controlling display in the display step based on an operation in the operation step, wherein the content information is stored in the display screen on the first screen. In the control step, when the content information is scrolled in accordance with an instruction in the operation step and sequentially displayed on the display screen in the display step, the first step is performed. In the area, the content information is updated every time one is scrolled. It indicated, previously in the second region, and controls to display and update the content information of the first area for each to plural scrolls.

  As described above, according to the content reproduction apparatus and the content information scroll display method of the present invention, the content information displayed in the second area can be read without frequently stopping the scrolling of the content information. Thus, it is possible to scroll while maintaining the scroll speed at a high speed while sequentially checking whether the content information of the desired content is displayed. In addition, since the content information displayed in the second area can also read characters after the initial character, it is possible to determine in more detail how far the scroll has been made, and the scroll speed until just before approaching the content information of the desired content. You can scroll while keeping Therefore, even if the scrolling of the content information is not stopped halfway and the number of contents is large, the time until selecting the content information of the desired content can be shortened.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram of a content playback apparatus 100 according to Embodiment 1 of the present invention. The content reproduction apparatus 100 includes a processor 101, a recording medium 102, an operation unit 103, a display unit 104, a speaker 105, and an external I / F 106. Here, an example of a portable digital audio player that reproduces music will be described as the content reproduction apparatus 100. However, the content reproduction apparatus and the content information scroll display method of the present invention are limited to a portable digital audio player. It is not something.

  The processor 101 operates as a control unit that controls the operation of the entire content reproduction apparatus 100. The recording medium 102 includes a small hard disk having a large capacity, a flash memory, or the like, and a plurality of music pieces are recorded as files. Hierarchical music information such as genre name, artist name, album name, title name, and the like is added to the music, and the user can select the music by using the music information as a clue. The music information may be recorded in the same file as the music, or may be recorded in another file. The operation unit 103 includes buttons, switches, dials, touch panels, and the like, and inputs user operations on the content playback apparatus 100 such as music selection. The display unit 104 includes a liquid crystal display, an organic EL display, and the like, and displays information such as music information to the user. The speaker 105 includes a speaker built in the content playback apparatus 100, external headphones, and the like, and outputs to the user the sound of the music read and played by the processor 101 from the recording medium 102. The external I / F 106 connects the content playback apparatus 100 to an external PC, minicomputer, or the like, and an interface (I / I) for the processor 101 to record music or the like transferred from the external PC, minicomputer, etc. on the recording medium 102. F) is provided.

  FIG. 2 is a plan view showing front panel 200 of content reproduction apparatus 100 according to Embodiment 1 of the present invention. The front panel 200 includes a display screen 201 of the display unit 104 and operation buttons 205 of the operation unit 103. The headphone 211 is detachably connected to the side surface adjacent to the upper side of the front panel 200.

  The display screen 201 includes a status area 202, a first area 203, and a second area 204. The status area 202 is an area where the processor 101 displays the operation status of the content reproduction apparatus 100. In the example of FIG. 2, the status area 202 indicates that a list of title names in the music information is being displayed and the remaining capacity of the internal battery of the content playback apparatus 100. In the first area 203 and the second area 204, the processor 101 displays three title names in the list of title names in a sorted list format over three lines. As shown in the example of FIG. 2, one title name may be displayed on one line, or one title name may be displayed on a plurality of lines. When one title name is displayed on one line, many title names can be displayed at the same time, and when one title name is displayed on multiple lines, all title names can be displayed even when the number of characters in the title name is large. Can display characters.

  The operation button 205 includes a center button 206, an upper button 207, a lower button 208, a left button 209, and a right button 210. Each button 206 to 210 is assigned a plurality of functions according to the operation status of the content reproduction apparatus 100. For example, when the user selects a song, the processor 101 detects that the down button 208 has been pressed for the title name displayed in the first area 203 and the second area 204 of the display screen 201. Scrolling and updating in the forward direction (downward in FIG. 2), and detecting that the upper button 207 has been pressed, scrolling and updating in the reverse direction (upward in FIG. 2). When the user plays the music, the processor 101 detects that the center button 210 has been pressed, reads the selected music file from the recording medium 102, decompresses the compressed data, and produces a digital signal. Playback, conversion to an analog signal, and output from the speaker 105 (headphone 211). When it is detected that the upper button 207 is pressed during reproduction, the processor 101 increases the volume output from the speaker 105. When it is detected that the down button 208 is pressed during reproduction, the processor 101 reduces the volume output from the speaker 105. When it is detected that the left button 209 is pressed during reproduction, the processor 101 moves the position on the time axis for reproducing the music to the beginning of the music in the forward direction. When it is detected that the right button 210 is pressed during reproduction, the processor 101 moves the position on the time axis for reproducing the music to the head of the music in the backward direction.

  FIG. 3 is a flowchart showing a method for scrolling content information according to the first embodiment of the present invention. A portion where the processor 101 displays title names in a list format in the first area 203 and the second area 204 of the display screen 201 and scrolls in the forward direction to sequentially display the title names is shown. Starting from the start point 301, after steps 302 to 311, when the title name is selected by the user, the end point 312 is reached, and the series of processing ends.

  First, in step 302, a variable n for counting the number of times the title name has been scrolled is initialized to zero. In addition, the value of the title name scrolling number I2, which is an interval for updating the title name displayed in the second area 204, is set. Next, in step 303, title names are displayed in a list format in the first area 203 and the second area 204 of the display screen 201. The title names are in sorted order.

  Next, in step 304, it is determined whether one of the title names displayed on the display screen 201 has been selected, or whether the center button 210 has been pressed by the user. When it is detected that the center button 210 has been pressed, the process proceeds to the end point 312 and the scrolling display of the title name is ended. Thereafter, the music corresponding to the selected title name is played back. If it is not detected that the center button 210 has been pressed, the process proceeds to step 305.

  In step 305, it is determined whether or not scrolling of the title name displayed on the display screen 201 is instructed, and whether or not the user presses the down button 208. If it is detected that the lower button 208 has been pressed, the process proceeds to step 306. If it is not detected that the down button 208 has been pressed, the process returns to step 304.

  In step 306, the title name displayed in the first area 203 of the display screen 201 is updated and displayed. In the example of FIG. 2, since two title names are displayed in the first area 203, the title name displayed at the lower position, which is the previous position with respect to the scroll direction, is displayed in the scroll direction. Is moved to the upper position, which is the rear position, and displayed, and the title name one title ahead of this title name that has not been displayed so far is newly placed at the lower position. indicate. Next, in step 307, the scroll count n is incremented.

  Next, in step 308, whether or not to update the title name displayed in the second area 204 is compared with the number of times of scrolling n and the interval I2 for updating the title name displayed in the second area 204. Judge with. If the number of scrolls n has reached the interval I2 for updating the title name displayed in the second area 204, the process proceeds to step 309. If the number of scrolls n has not reached the interval I2 for updating the title name displayed in the second area 204, the process returns to step 304.

  In step 309, the title name displayed in the second area 204 of the display screen 201 is updated and displayed. In the example of FIG. 2, since one title name is displayed in the second area 204, the title name I2 ahead of the title name displayed at this position, which has not been displayed so far. Is displayed at this position. Next, in step 310, the scroll count n is initialized to zero.

  In the case where the value of the title name scrolling number I2, which is an interval for updating the title name displayed in the second area 204, is made variable, next, in step 311 the title name displayed in the second area 204 is displayed. The interval I2 for updating is reset. If the value of the interval I2 for updating the title name displayed in the second area 204 is not variable, step 311 is unnecessary. In either case, the process returns to step 304 next.

  When step 311 is not executed, the value of the interval I2 for updating the title name displayed in the second area 204 is fixed. In this case, in step 302, a predetermined value may be set for the interval I2 for updating the title name displayed in the second area 204, or a value corresponding to the number of title names (number of music pieces) is set. May be.

  As an example of setting the value according to the number of title names, the total number of times of updating the title name displayed in the second area 204 when the title name is scrolled from the beginning to the end is set to a predetermined value. As the number of title names increases, the interval I2 for updating the title names displayed in the second area 204 can be increased. By doing this, even if the number of music pieces increases, it is possible to increase the scroll speed while sequentially checking whether the title name of the desired music piece is displayed.

  When step 311 is executed, the value of the interval I2 for updating the title name displayed in the second area 204 is variable. In this case, in step 311, the interval I2 for updating the title name displayed in the second area 204 is reset.

  As an example of changing the value of the interval I2 for updating the title name displayed in the second area 204, the scroll speed is detected and the interval I2 for updating the title name displayed in the second area 204 is set to the scroll speed. You may set to the value according to. For example, it is conceivable that the interval I2 for updating the title name displayed in the second area 204 is increased stepwise as the scroll speed increases. In this way, even if the scrolling speed is increased, the title name update time interval is maintained without being extremely reduced to the extent that it is possible to sequentially check whether the title name of the desired song is displayed. can do.

  Further, although not included in the flowchart shown in FIG. 3, as another example in which the value of the interval I2 for updating the title name displayed in the second area 204 is made variable, the title name update time interval is set to a predetermined value. It is also possible to make time. In this case, for every predetermined time interval, the interval I2 for updating the title name displayed in the second area 204 may be set to the number scrolled at the time interval. In this way, even if the scrolling speed is increased, the title name update time interval is maintained without being extremely reduced to the extent that it is possible to sequentially check whether the title name of the desired song is displayed. can do.

  As another example of changing the value of the interval I2 for updating the title name displayed in the second area 204, when the title name is divided into a plurality of groups, the group to which the title name belongs changes. Sometimes it is possible to update the title name. This makes it easier to recognize how far the title name has been scrolled by recognizing changes in the title name group.

  As an example of a title name group, for example, it can be considered that the title name is divided into groups having the same number of characters from the beginning. That is, when the characters from the first character are divided into the same group, for example, the title name is updated when the initial character of the title name changes from “A” to “B”. When the first two characters are divided into the same group, for example, the title name is updated when the title name changes from "AA ..." to "AB ...".

  Also, for example, in reading, it can be considered to divide into a group having the same number of characters from the beginning to the predetermined number. In languages such as Japanese, it is easier to recognize them by dividing them into groups according to how they are read. That is, when the characters from the first character are divided into the same group, for example, the title name is updated when the initial character of the title name changes from “A” to “I” in reading. When the first two characters are divided into the same group, for example, the title name is updated when the title name changes from “Ah…” to “Ai…” in reading.

  Further, for example, the music information such as the title name has a hierarchical structure in which the album name is in the upper hierarchy of the title name, the artist name is in the upper hierarchy of the album name, and the genre name is in the upper hierarchy of the artist name. Can be divided into groups having the same album name or the like, which is the upper layer of the title name. For example, when the title name is displayed for each artist name to which the title name belongs and the title name is displayed in a list format in such an order that the artist name is also sorted, The title name is updated. In this case, instead of displaying the title name in the second area 204, the artist name may be displayed. Similarly, when the music information such as the title name is divided into groups having the same album name, which is the upper hierarchy of the title name, the title name may be updated and displayed when the album name changes. Instead of displaying the title name in the second area 204, the album name may be displayed.

  In the flowchart shown in FIG. 3, it is described that there are a plurality of title name scroll numbers I2 that are intervals for updating the title names displayed in the second area 204. It does not have to be. For example, when the scroll speed is detected and the scroll speed is lower than a predetermined value, the title name is updated and displayed every time one title is scrolled in both the first area 203 and the second area 204. When the scroll speed is higher than a predetermined value, the value of the interval I2 for updating the title name displayed in the second area 204 may be plural. In this way, when the scroll speed is high, the title names displayed in the second area 204 can be confirmed sequentially, and when the scroll speed is low, in addition to the first area 203 The title name of a desired music piece can be selected from a larger number of title names displayed in the area including the second area 204.

  In the flowchart illustrated in FIG. 3, the title name displayed in the first area 203 has been described as being updated by moving the displayed position one by one, but the title name displayed in the second area 204 is displayed. As long as it is smaller than the number I2 of scrolls of title names, which is the interval for updating the title, it may not be every one. For example, when the scroll speed is detected and the scroll speed is smaller than a predetermined value, the title name displayed in the first area 203 is scrolled by one each time it is detected that the operation button 205 is pressed. When the scroll speed is higher than a predetermined value, a plurality of title names displayed in the first area 203 are scrolled each time it is detected that the operation button 205 is pressed. You may update and display. At this time, the scroll speed may be increased by detecting that the operation button 205 is pressed and held. By doing so, the scrolling speed can be further increased.

  FIG. 4 is a diagram showing update of the display screen 201 of the display unit 104 of the content reproduction apparatus 100 according to Embodiment 1 of the present invention. The screen images 400 to 490 displayed on the display screen 201 detect that the down button 208 is pressed after the processor 101 starts displaying the title names in the list format in the screen image 400, and the screen image 430 is detected. 7 shows a screen image when the forward scrolling is started and thereafter the display screen 201 is sequentially updated by the forward scrolling. In the example of FIG. 4, the number of title name scrolls, which is the interval for updating the title name displayed in the second area 204, is a fixed value of ten.

  In the screen image 400, the display screen 201 includes a first area 203 and a second area 204. The second area 204 is arranged above the first area 203, that is, rearward with respect to the forward scroll direction (downward in FIG. 4).

  In the first area 203 and the second area 204, the processor 101 displays the first three title names in the list of title names in order from top to bottom, and the first title name “title_01”. Is the title name 402 at the position of the second area 204, the second title name “title — 02” is the title name 403 at the position above the first area 203, and the third title name “title — 03” is the first 1 is displayed as the title name 404 at the lower position of the area 203. The title name 402 at the position of the second area 204 can display the same number of characters as the title name 403 at the upper position of the first area 203 and the title name 404 at the lower position.

  The pointer 401 is an index for pointing to the selected title name. In this example, the pointer 401 points to the title name 402 at the top position. The indicator for indicating the selected title name may be a highlight display or the like. In addition, the bar 405 indicates in which position the title name displayed on the display screen 201 is in the order in the entire list of title names.

  When the processor 101 detects that the down button 208 has been pressed, the processor 101 updates the screen image 410. In the screen image 410, the pointer 401 in the screen image 400 moves downward and is updated as a pointer 411 for pointing to the title name 413 at the middle position.

  When the processor 101 detects that the lower button 208 is further pressed, the processor 101 updates the screen image 420. In the screen image 420, the pointer 411 in the screen image 410 moves further downward and is updated as a pointer 421 for pointing to the title name 424 at the lowest position.

  When the processor 101 detects that the lower button 208 is further pressed, the processor 101 updates the screen image 430. In the screen image 430, the title name 424 “title_03” at the lower position of the first area 203 in the screen image 420 moves upward and becomes the title name 433 at the upper position of the first area 203. Is displayed. In addition, the fourth title name “title_04” that has not been displayed in the screen image 420 is newly displayed as the title name 434 at the lower position of the first area 203. In this way, the display of “title_02” and “title_03” is updated to the display of “title_03” and “title_04”, and forward scrolling is started.

  In the screen image 430, the title name 422 “title_01” at the position of the second area 204 in the screen image 420 is not updated and remains displayed as the title name 432 at the position of the second area 204. . However, in order to distinguish the title name displayed in the second area 204 from the title name displayed in the first area 203, a frame 436 having a predetermined background color is added to the title name 432. ing. By displaying the information in an identifiable manner, the user can recognize that the first area 203 and the second area 204 are scrolling with different title name update methods. For example, other methods such as blinking of characters and display of a frame line may be used as the method for enabling identification.

  By sequentially updating the display screen 201 in this way, it is possible to seamlessly connect from the screen image 420 before the scroll start to the screen image 430 after the scroll start. In addition, after scrolling has started, the second area 204 only needs to display a minimum amount of information that can be used to sequentially check how much scrolling has progressed with respect to the title name of the desired song. It is sufficient that at least one title name can be displayed.

  When the processor 101 detects that the lower button 208 is further pressed, the processor 101 updates the screen image 440 in the same manner. In the screen image 440, the title name 434 at the lower position of the first area 203 in the screen image 430 moves upward and is displayed as the title name 443 at the upper position of the first area 203. In addition, the fifth title name that has not been displayed in the screen image 430 is newly displayed as the title name 444 at a position below the first area 203.

  Thereafter, in the same manner, the screen image is sequentially updated. In the screen image 450, the title name “title_01” as the title name 452 at the position of the second area 204 is replaced with the title at the upper position of the first area 203. The title name “title_11” is displayed as the name 453, and the title name “title_12” is displayed as the title name 454 at the lower position of the first area 203.

  When the processor 101 detects that the lower button 208 is further pressed, the processor 101 updates the screen image 460. In the screen image 460, the title name 454 “title_12” at the lower position of the first area 203 in the screen image 450 moves upward and becomes the title name 463 at the upper position of the first area 203. Is displayed. In addition, the 13th title name “title_13” that has not been displayed in the screen image 450 is newly displayed as the title name 464 at the lower position of the first area 203.

  In the screen image 460, the title name 453 “title_11” at the upper position of the first area 203 in the screen image 450 moves upward and is displayed as the title name 462 at the position of the second area 204. Is done. As described above, in the second area 204, the display of “title name — 01” is updated to the display of “title name — 11”, and the display of title names is updated at intervals of ten.

  By sequentially updating the display screen 201 in this way, when updating the title name displayed in the second area 204, it is possible to connect seamlessly as in the update from the screen image 450 to the screen image 460.
