  The display unit 20 includes, for example, a liquid crystal display element, an organic EL (Electro Luminescence) display element, and the like, and displays various types of information under the control of a display control unit 151 described later.

  The storage unit 30 is a storage element that stores various content data, and includes, for example, an HDD (Hard Disk Drive) or a flash memory. In addition, the storage unit 30 is not limited to the one built in the content display device 100, and may be an external storage device connected to a predetermined interface or a predetermined connection terminal that functions as the input / output unit 50. Examples of the external storage device include a USB memory connected to a USB (Universal Serial Bus) terminal, an external HDD device, and a memory card connected by a predetermined memory card slot.

  The operation unit 40 receives an operation instruction from the user for the content display device 100 and sends the received operation instruction signal to the operation control unit 152 described later. As a specific example of the operation unit 40, a mechanical switch or touch sensor provided on the surface of the content display device 100, a touch panel operation unit 41 provided on the display unit 20 or the content display device 100 is wired or wireless. A remote control device (not shown) that is operated by communication.

  Examples of operations accepted by the touch panel operation unit 41 include flick operations and tap operations. Specifically, the tap operation is an operation in which the user taps a desired position on the surface of the touch panel operation unit 41 superimposed on the display unit 20. Similarly, the flick operation is an operation of sliding from a desired position in a desired direction or a paying operation.

  When the operation unit 40 is the touch panel operation unit 41, various operations based on display contents are performed in conjunction with display processing by the display control unit 151 described later. For example, a scroll process by a flick operation on a screen on which a plurality of items are displayed in a list, a selection process by a tap operation for displaying a specific item, a reproduction process, or the like.

  The input / output unit 50 is an interface for inputting or outputting various data including content data to the content display device 100. Specifically, the input / output unit 50 includes a USB terminal, an HDMI (High-Definition Multimedia Interface: registered trademark) terminal, and a memory card slot. Etc. The input / output unit 50 may be an analog signal input / output terminal. Various data input by the input / output unit 50 may be displayed on the display unit 20 by processing of the display control unit 151 and stored in the storage unit 30 by processing of the control unit 10 as necessary.

  The input / output unit 50 includes a DAC (Digital Analog Converter) that converts digital data to be output into analog signals, an ADC (Analog Digital Converter) that converts input analog signals into digital data, and data and inputs to be output. An amplification unit that amplifies the generated data or signal may be included. The input / output unit 50 may be an image sensor that acquires image data, a microphone that inputs an audio signal, a speaker that outputs an audio signal, and the like.

  As shown in FIG. 2, the control unit 10 includes a display control unit 151, an operation control unit 152, a playback control unit, an item extraction unit 154, and an initial extraction unit 155 as functions realized by the above-described components. The

  The display control unit 151 performs processing for displaying various information on the display unit 20. For example, a process for displaying a content list screen, a content initial screen, and an image or video related to the content stored in the storage unit 30 is performed. In addition, when a scroll display instruction is input from the operation unit 40 to these list screens, the display control unit 151 performs a process of scrolling these list screens.

  The operation control unit 152 executes processing based on the operation signal acquired from the operation unit 40. For example, when a content selection instruction or a content reproduction instruction is executed by the operation unit 40, the operation control unit 152 generates a signal corresponding to the executed instruction, and the display control unit 151 displays the content selected. To cause the playback control unit 153 to play back the content.

  The reproduction control unit 153 performs content reproduction based on the operation of the operation unit 40 and other processes. When the content includes image data or video data, the playback data of the content by the processing of the playback control unit 153 is displayed on the display unit 20 under the control of the display control unit 151, and the content includes audio data. If included, it is output from the output terminal or speaker of the audio signal or audio data in the input / output unit 50.

  The item extraction unit 154 extracts various items from information related to content to be played back by the playback control unit 153 such as content stored in the storage unit 30. An example of information related to the content is tag information added to the content, and as an example, corresponds to an ID3 tag when the content is MP3 format audio data.

  Examples of items extracted by the item extraction unit 154 include a music name that is the name of the content, a genre of the content, an album name to which the content belongs, and an artist name that is the performer or singer of the content. Each item extracted by the item extraction unit 154 is displayed as a list of contents, and enables sorting search and the like for each item.

  The initial character extraction unit 155 extracts the initial character for each item extracted by the item extraction unit 154. As a specific example, when the music name is “BBCCCC”, the initial “B” of the music name is extracted. When the album name is “XXX”, the initial “X” of the album name is extracted. When the artist name is “YYXX”, the initial “Y” of the artist name is extracted. When the genre name is “Jazz”, the initial “J” of the genre name is extracted. When an initial letter extracted by each item includes uppercase letters and lowercase letters, the uppercase letters and lowercase letters may be treated as different initial letters or as the same initial letters.

  For example, when a kanji character is used for each item name, the initial character extraction unit 155 extracts an initial character based on a sound representing the reading of the kanji character. As a specific example, in the case of the song name “Spring No ...”, the initial “ha” of the song name is extracted. When the album name is “Four Seasons ...”, the initial “shi” of the album name is extracted. The same applies to artist names and genre names. When the initial character extracted by the initial character extraction unit 155 is a katakana character, it is preferable to replace it with hiragana.

  As in the example described above, the initial character extraction unit 155 applies a common initial character as the initial character to be extracted even if the items are different. For example, if the song name, artist name, etc. contain Japanese characters consisting of kanji, hiragana or katakana, the initial letters of the song name, artist name, album name, and genre name will be the letters “A” to “Z”. , Arithmetic numbers, hiragana “a” to “n”.

  In addition, as the specification in the English-speaking region, the initial letter extraction unit 155 sets the initial letters in each item as English letters “A” to “Z” and arithmetic numbers. The German-speaking specifications are English letters “A” to “Z” plus umlauts and numbers. In this way, an acronym suitable for each language can be used.

  FIG. 3 is an example of an external perspective view when applied to a smartphone as one form of the content display device 100.

  Is a rectangle, and includes a display unit 20 and a touch panel operation unit 41 which is an operation unit 40 superimposed on the display unit 20 on one surface. The input / output unit 50 includes a microphone and an audio output terminal. Although not shown in the figure, switches as the operation unit 40, speakers or an imaging device as the input / output unit 50 may be provided. Although not shown in FIG. 1, the content display device 100 has a built-in communication unit that enables communication via a mobile phone line, a public wireless LAN, and Bluetooth (registered trademark).

  In the case of the content display device 100 having the form as shown in FIG. 3, a list of contents and a list of initials are displayed on the display unit 20, and selection and scrolling operations thereof are mainly performed by operations by the touch panel operation unit 41. Is called.

  Next, display processing of the content display apparatus 100 according to the present invention will be described with reference to FIGS.

  First, an example in which a content list before searching by initials is displayed will be described with reference to FIG. FIG. 4 is a diagram simulating the display screen 200 in the display unit 20, and is an example in which a list of music contents is displayed in order of music names as an example. In this case, the display screen 200 includes a screen information display area 210, a content list display unit 221, and a content list selection area 230.

  In addition to these, the display screen 200 may include other displays such as an icon indicating the remaining battery status of the content display device 100, an icon indicating the electric field strength in various communication methods, and the display of the current time.

  The screen information display area 210 displays information representing the content displayed on the display screen 200. In the example of FIG. 4, the characters “Music Title List” are displayed together with an icon indicating that the list is displayed in the order of music titles. In the screen information display area 210, an initial search activation icon 211 for displaying an initial search pop-up screen is displayed. When the initial search activation icon 211 is operated by the user, an initial list display unit 250 described later is superimposed on the content list display unit 221.

The content list display unit 221 displays a list of contents based on the selected list display. In the example of FIG. 4, the list display in the order of music titles is selected, so that the contents to be played are listed in the order of the music titles.

  The content list display unit 221 displays, as an initial screen, the contents of music titles starting with the English letter “A” sorted from the top, and scrolls the content list by flicking on the content list display unit 221. Can do. In addition, it is possible to instruct selection or reproduction of content by tapping a part where arbitrary content is displayed.

  The content list display unit 221 displays a plurality of sections for each content, and displays, for each section, a song name as an item name in the example of FIG. 4 and an artist name corresponding to the song name. In the example of FIG. 4, the music name is “AAAABBBB” and the artist name is “DDDDDDDDD” as the contents of the section displayed first in the list of the initial letter “A”. In addition, album names, genre names, album jacket images, and the like may be displayed.

Furthermore, as content to be played back, the content stored in the storage unit 30 built in the content display device 100 and the content display device 100 can be played back, but are stored in other devices or other storage media. The reproducible content may be displayed via the communication means. As an example in this case, the other device content icon 240 is displayed together with the name of the content or the like that makes it possible to visually recognize the content that is stored in another device or another storage medium and can be played back via the communication means. In this case, the content having the music name “BCDDDDDD” and the artist name “PPPPP” is not stored in the storage unit 30 and can be played back from another device or the like.

  In the example of FIG. 4, the content list display unit 221 includes a content list display unit 221 </ b> A that displays a list of content that starts with the initial “A”, and content that displays a list of content that starts with the initial “B”. A list display portion 221B is displayed. In addition, an initial index 220A is displayed at the top of the content list display unit 221A, which indicates a position where a list of contents starting with the initial letter “A” starts. Similarly, an initial index 220B is displayed at the top of the content list display unit 221B, indicating that the list of contents starting with the initial letter “B” is the starting position.

  In the content list selection area 230, icons or the like for selecting which items are displayed in the content list display unit 221 are displayed. In the example of FIG. 4, a genre name search icon 231, an artist name search icon 232, an album name search icon 233, a song name search icon 234, and a playlist search icon 235 are displayed in the content list selection area 230. A list of contents corresponding to a desired icon is displayed on the contents list display unit 221 by performing a tap operation or the like for these icons. In addition to these icons, a play / pause icon 236 is also displayed.

  Next, the initial character search process for a desired item of content will be described with reference to FIG.

  First, the user selects a desired icon in the content list selection area 230 by operating the touch panel operation unit 41 (step S101). In step 101, when a desired icon is selected and an item to be displayed is determined, the item extraction unit 154 extracts the item selected based on the tag information of the content and the display control unit 151. Are sorted and displayed on the display unit 20 based on the extracted items (step S102). The screen displayed here is the content list display unit 221 in the example of FIG. 4, and this is the first list screen.

  In step S102, in a state where the content list display unit 221 is displayed, the operation control unit 152 determines whether or not the initial search activation icon 211 has been operated (step S103). If it is determined in step S103 that the initial letter search activation icon 211 has been operated (step S103: Yes), the initial letter extraction unit 155 extracts the initial letter of the content in the item selected in step S101 (step S104). ). If it is determined in step S103 that the initial letter search activation icon 211 has not been operated (step S103: No), the process proceeds to step S111 described later.

  The display control unit 151 causes the display unit 20 to sort and display based on the initial characters extracted in step S104 (step S105). The screen displayed here is displayed as an initial list display unit 250 shown in FIG. 6 and is referred to as a second list screen.

  Here, the display screen when the initial search activation icon is operated will be described with reference to FIG. 6 shows a state in which the initial search activation icon 211 is operated in the state of FIG. 4, and therefore the content list display unit 221 in FIG. 6 is the same as FIG. In FIG. 6, the initial list display unit 250 is displayed as a pop-up screen so as to overlap a part of the content list display unit 221.

  The initial list display unit 250 is configured with an initial information display area 251. In the initial information display area 251, characters of “Initial Search” indicating a screen for searching for initial characters are displayed. The In the initial information display area 251, an initial list display part end icon 252 is displayed.

  The initial list display unit 250 is displayed on the content list display unit 221 on a small screen both in the vertical and horizontal directions. In particular, it is desirable that the content list display unit 221 be displayed at the center on the right side. This is because the visibility of the content list in the content list display unit 221 is not sacrificed at the same time as the initial search is performed with this arrangement. The initial list display unit 250 may allow the display position and display size to be changed by a user operation, but the default value is preferably the above condition.

  The initial letter list display unit 250 starts with the upper left of the initial letter list display unit 250 as the extracted initial letters, and five English letters “A” to “Z” are arranged in one line, and the alphabetical letters are continuously calculated. Numbers are arranged. In the case of Japanese specifications, in addition to these, hiragana is similarly arranged in five characters per line. The number of characters arranged in one line is not limited to five, but by arranging the hiragana in five characters per line, the arrangement in the vertical direction represents the sound of “Adan” “Akasana ...” Therefore, there is an effect that it is easy to intuitively grasp the scroll position when performing the scroll display in the vertical direction.

  The number of characters in the vertical direction of the initial character list display unit 250 is not particularly limited, but is preferably the number of lines that can be easily grasped when scroll display of 3 to 5 lines is performed. Also, as shown in the example of FIG. 6, if there are more lines after the “PQRST” line, a gradation is added so that the characters displayed on the bottom line gradually become lighter. Also good. This makes it possible to intuitively understand that there are more initial characters after the lowest line.

  In the example of FIG. 6, the list of contents starting with “A” is displayed at the top as the list of contents displayed in the content list display unit 221. When the search activation icon 211 is operated, the initial list display unit 250 is displayed so that “ABCDE” is the top line. For example, when the content list display unit 221 is scrolled and a list of contents whose music name starts with “G” is displayed at the top, when the initial search activation icon 211 is operated, “FGHIJ” is the most. The initial list display unit 250 is displayed so as to be in the upper row.

  Returning to FIG. 5, after the initial list display unit 250 is displayed in step S <b> 105, the operation control unit 152 determines whether or not a flick operation has been accepted for the display position of the initial list display unit 250 in the touch panel operation unit 41. Is determined (step S106). If it is determined in step S106 that the flick operation has been accepted (step S106: Yes), the display control unit 151 scrolls the initial list display unit 250 in the direction of the flick operation and also displays the initial list display unit 250. The content list of the content list display unit 221 is also scroll-displayed in the same direction in synchronization with the scroll display (step S107). If it is determined in step S106 that a flick operation has not been accepted (step S106: No), the process proceeds to step S108.

  The scroll display of the content list display unit 221 synchronized with the scroll display operation of the initial character list display unit 250 in step S107 will be described with reference to FIGS.

  For example, in the state shown in FIG. 6, the user operates the touch panel operation unit 41 to perform an operation of scrolling the initial list display unit 250 upward in the display screen 200. By this operation, the uppermost line of the initial list display section 250 changes to “FGHIJ”, “KLMNO”,. In accordance with this transition, when the top line of the initial list display unit 250 is “FGHIJ”, the content list display unit 221 displays the content list starting with “F” at the top. Display. Specifically, an initial index 220F is displayed at the top of the content list display unit 221 to indicate that the list of contents starting with the initial letter “F” is to be started. Subsequently, a list of contents starting with the initial letter “F” is displayed.

  In the example of FIG. 7, a state in which the top line of the initial list display unit 250 becomes “UVWXY” by the operation of scrolling the initial list display unit 250 is shown. In FIG. 7, content corresponding to the initials “U”, “Y”, “Z”, “numbers”, “e” does not exist as content to be played back from the storage unit 30 or other devices. , Each initial is displayed in a light color tone. In this case, although the top row of the initial list display unit 250 is “UVWXY”, the content corresponding to the initial “U” is the playback target of the storage unit 30 or another device. Since there is no content, the content list display unit 221 displays a list of the initial “V” in which the content exists after the initial “U” as a result of the scroll display.

  Returning to FIG. 5, after performing the scroll display operation of the initial list display unit 250 in step S107, or while it is being performed, or when it is determined that the flick operation is not accepted in step S106, the operation control unit 152 determines whether or not a selection operation has been performed on the initial characters displayed in the initial character list display unit 250 (step S108).

  If it is determined in step S108 that a selection operation has been performed on the initial character (step S108: Yes), the display control unit 151 deletes the initial character list display unit 250 and also displays content corresponding to the selected initial character. Is displayed on the top of the content list display unit 221 (step S109). In this case, the erasure of the initial list display unit 250 is not essential, and may be erased after a predetermined time has elapsed since the selection operation for the initial character was performed, or may be erased after the process of step S111 described later. . Alternatively, the user may be deleted only by operating the initial list display unit end icon 252 displayed on the initial list display unit 250.

  In step S108, when it is determined that the selection operation for the initial character is not performed (step S108: No), the display control unit 151 determines whether or not the end process for the display of the initial character list display unit 250 has been performed. (Step S110). The display end processing of the initial list display unit 250 in this case is a case where a predetermined time has passed without any operation after the initial list display unit 250 is displayed, or when the user starts the initial list display unit This is a case where the initial list display part end icon 252 displayed in 250 is operated.

  In step S110, when it is determined that the termination process for the display of the initial list display unit 250 has been performed (step S110: Yes), the process proceeds to step S111 described later. If it is determined that the termination process for the display of the initial letter list display unit 250 has not been performed (step S110: No), the process proceeds to step S106.

  Here, the process of step S109 will be described with reference to FIG. 8 from the state in which it is determined in step S108 that the selection operation for the initial character has been performed.

  In the example of FIG. 8, the initial “M” is selected by the user for the initial list display unit 250. For convenience, the letter “M” is circled so that it can be determined that the initial letter “M” is selected, but the display control unit 151 does not need to perform such circled display. It is good also as a display accompanied by the visual effect.

  In FIG. 8, since the initial “M” is selected by the user, a list of contents corresponding to the initial “M” is displayed at the top of the content list display unit 221. In this way, since the list of contents corresponding to the selected initial is associated with the content list display unit 221, the user can select desired content immediately from the initial. In addition, even when the initial list display unit 250 is displayed, the content list display unit 221 can be visually recognized in conjunction with the operation on the initial list display unit 250. There is no need to do this, and the desired content can be selected directly.

  After the process of step S109 or when step S110 is Yes, the operation control unit 152 determines whether or not the content displayed on the content list display unit 221 has been selected by the user (step S111).

  If it is determined in step S111 that content has been selected (step S111: Yes), predetermined processing is performed on the content selected by the corresponding function in the control unit 10 (step S112). The predetermined processing in this case is content reproduction processing by the reproduction control unit 153 as an example. A reproduction process may be uniquely executed on the content selected by the initial character selection operation. The user may be able to select a process to be executed on the selected content. Examples of processing other than playback processing include content deletion, content name change, content tag information editing, content registration in a playlist, and the like.

  After the predetermined process in step S112 is executed, this process is terminated. Depending on the processing contents in step S112, after the execution of the processing, the display screen before the processing in step S112 may be returned.

  If it is determined in step S111 that no content has been selected (step S111: No), the display control unit 151 determines whether or not a termination process for the display of the content list display unit 221 has been performed (step S113). . In this case, the display end processing of the content list display unit 221 includes a case where a predetermined time has elapsed without selection of content, or the content list display unit 221 based on other items displayed in the content list selection area 231. For example, a display request or a process of switching to another function of the content display apparatus 100 is performed.

  In step S113, when it is determined that the end process for the display of the content list display unit 221 has been performed (step S112: Yes), this process ends. When it is determined that the end process for the display of the content list display unit 221 has not been performed (step S112: No), the process proceeds to step S106.

  The embodiment of the present invention can be variously modified without departing from the gist thereof. In the above embodiment, the scroll display of the initial list display unit 250 has been described only in the vertical direction. For this reason, the initial characters displayed at the top of the content list display unit 221 in synchronization with the scroll display of the initial character list display unit 250 are the initial characters displayed in the leftmost column of the initial character list display unit 250. Was preferentially displayed.

  FIG. 9 shows an example in which scroll display of the initial list display unit 250 is enabled in an arbitrary direction. As the arbitrary direction, scroll display in the vertical direction and horizontal direction may be effective, and scroll display in an oblique direction may be enabled.
