Description

  The present invention relates to a content information display device capable of displaying only one piece of content information in a content list and displaying all content information by scrolling display of the content information in the content list.

  The following Patent Document 1 describes a content reproduction system including a portable player 11, a charging device 12, and an amplification device 13. The portable player 11 is connected to the charging device 12 via connection connectors for voice and communication. The charging device 12 is connected to the amplifying device 13 via an audio (and communication if necessary) cable. The charging device 12 transmits to the portable player 11 an instruction to reproduce the song selected by the user. In response to the reproduction instruction, the portable player 11 reproduces the specified song and transmits an audio signal to the charging device 12. The charging device 12 transmits the audio signal received from the portable player 11 to the amplifying device 13. The amplifying device 13 amplifies the audio signal received from the charging device 12 and reproduces music through a speaker (not shown).

  The charging device 12 includes a display unit that can display only one song name selected from a content list that is a list of content information (for example, song names) of content stored in the portable player 11. In order for the user to select a desired song name, when the desired song name is displayed on the display unit, it is necessary to scroll the song name displayed on the display unit. Here, when the number of song names in the content list is enormous, it takes a lot of time to scroll the display of the song name and reach the desired song name. Therefore, it is required to scroll the display of the song title at high speed.

  However, if the display time of one song name during scrolling is less than 100 msec, it is difficult to recognize the displayed character string, and as a result, it is difficult to recognize which song name is currently displayed. is there. On the other hand, when scrolling while displaying all the song names in the content list with a display time of 100 msec or longer enough to recognize the character string, it takes a long time to reach the desired song name as described above. There's a problem. Such a problem is not a problem peculiar to the reproduction system as described above, but a content information display applied to a content reproduction apparatus having an HDD or a flash memory, or a client apparatus that acquires and reproduces content from a server via a network. The same occurs in the apparatus.

Patent No. 3894226

  An object of the present invention is to provide a content information display device that can increase the scroll speed of content information and allows a user to recognize a character string of the displayed content information.

  A content information display device according to a preferred embodiment of the present invention is a content information display device that scrolls and displays content information in a content list including a plurality of sorted content information, and is selected from the content list. Display means for displaying only one piece of content information, input means for inputting an instruction to scroll the display of the content information on the display means in response to a user operation, and a character string for a predetermined number of characters from the top of the content information. A calculation means for calculating the display time of each piece of content information so that the same content information or a plurality of pieces of content information is set as one group, and the total display time of the content information in the one group is a predetermined time; The content information is continuously displayed on the display means for the display time calculated by the means. By, and a display control means for scrolling the content information in the content list.

  The calculation means sets one or a plurality of pieces of content information having the same character string for the predetermined number of characters from the beginning of the content information as one group, and sets each content information in the group to a predetermined time so that the total display time is a predetermined time. The display time of content information is calculated. Therefore, the scroll speed of the displayed content information can be improved as compared with the conventional case where the display time of all the content information is set to a predetermined time. That is, the number of content information scrolled within a certain time can be increased, and the user can quickly reach the content information desired by the user. In addition, since only the content information having the same character string for the predetermined number of characters from the beginning is scrolled at a speed higher than the predetermined time, the character string for the predetermined number of characters from the beginning is scrolled at a speed higher than the predetermined time. Fixed and not changed. Therefore, the user can clearly recognize only a predetermined number of character strings from the beginning whose display is not changed even when scrolling. That is, when attention is paid only to a character string of a predetermined number of characters from the top, all content information is scrolled in a predetermined time. As a result, it is possible to easily recognize whether or not the currently displayed content information is the content information desired by the user, even though scrolling at high speed.

  In a preferred embodiment, the calculating means includes a character string for a predetermined number of characters from the beginning of the content information included in the content list, and a character string for a predetermined number of characters from the beginning of the content information to be displayed on the display means. Is counted as the number of continuous display contents, and the time obtained by dividing the predetermined time by the number of continuous display contents is set as the display time of each content information.

  In this case, it is possible to make all the pieces of content information in the group having the same number of character strings from the top the same display time.

  In a preferred embodiment, the calculation means subtracts 1 from the number of continuous display contents each time the content information displayed on the display means is scrolled, and calculates the display time of the content information until the number of continuous display contents becomes zero. Is not executed, and the display time of the content information is set to the display time calculated immediately before.

  In this case, the display time is calculated for the first content information in the group having the same character string for the predetermined number of characters from the beginning, and the display time is used as the display time for other content information in the group. . As a result, it is only necessary to calculate the display time for the first content information in the group, so the processing becomes simple.

  In a preferred embodiment, the calculating means sets the continuous display content number to a predetermined upper limit value when the continuous display content number exceeds a predetermined upper limit value.

  In this case, since the number of pieces of content information in the group is too large, it is possible to prevent the display time of each piece of content information from becoming too short.

  According to the present invention, it is possible to easily recognize whether or not the currently displayed content information is the content information desired by the user, even though the content information is scrolled at a high speed.

  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 schematic diagram illustrating a content reproduction system including a content information display device 12 according to a preferred embodiment of the present invention. The content reproduction system includes a content reproduction device 11 (for example, a portable player, details are shown in FIG. 5), a content information display device 12 (for example, a charging device 300, details are shown in FIG. 6), and an amplification device 13. . The content information display device 12 is typically provided in a charging device 300 that supplies a power supply voltage to the battery of the portable player 11. However, the present invention is not limited to this, and the content information display device 12 may be provided in another device (for example, the amplification device 13 or the portable player 11). The content is a general term for music (song), video, and / or still image, and may be digital or analog, and may be compressed data or non-compressed data. In this example, the case where the content is music (voice) will be described as an example.

  The portable player 11 is connected to the content information display device 12 via connection connectors for audio and communication. The content information display device 12 is connected to the amplifying device 13 via an audio (and communication if necessary) cable. The charging device 300 transmits to the portable player 11 an instruction to reproduce the song selected by the user. In response to the reproduction instruction, the portable player 11 reproduces the specified song and transmits an audio signal to the charging device 300. The charging device 300 transmits the audio signal received from the portable player 11 to the amplifying device 13. The amplifying device 13 amplifies the audio signal received from the charging device 300 and reproduces music through a speaker (not shown).

  The content information display device 12 acquires a content list as shown in FIG. 2 from the portable player 11, for example. The content list is a list of content information related to content stored in the portable player 11. The content information includes a song name, artist name, album name, genre name, and the like. Here, the case of a song name will be described as an example. Each song name in the content list is given a serial number (1 to N), and each song name is sorted in alphabetical order (or alphabetical order, numerical order) and ascending order (or descending order). Has been (sorted).

  As shown in FIG. 3, the content information display device 12 includes a display unit 307 and an input unit 308. The display unit 307 can display only one song name selected from the content list acquired from the portable player 11. The input unit 308 is used to input an instruction from the user by a user operation, and includes, for example, an UP button, a DOWN button, a determination button, a PLAY / PAUSE button, a power button, and the like. When the UP button or the DOWN button is kept pressed by a user operation, the song names displayed on the display unit 307 are continuously switched in ascending order or descending order (hereinafter, the continuous display switching is referred to as scrolling). When the DOWN button is kept pressed, the music title displayed on the display unit 307 is scrolled in the direction in which the content number increases in the content list of FIG. When the UP button is kept pressed, the song title displayed on the display unit 307 is scrolled in the direction in which the content number is decreased in the content list of FIG. The PLAY / PAUSE button is a button for causing the portable player 11 to play the song displayed on the display unit 307 when pressed while the song name is displayed on the display unit 307.

  When the content information display device 12 scrolls the display of the song name, the content information display device 12 calculates the display time of each song name based on the correlation between the song name displayed on the display unit 307 and the character string before and after the song name, The song name is displayed on the display unit 307 for the calculated time. Specifically, one or a plurality of song names having the same character string for a predetermined number of characters (three characters in this example, although not particularly limited) from the beginning of the song name are set in one group. Then, the display time of each song name is determined so that the total display time of the song names in each set group becomes a predetermined time. Here, the predetermined time is the shortest time in which the user can sufficiently recognize the character string, and is set in advance to 100 msec (millisecond, the same applies hereinafter) in this example.

  FIG. 4 is a diagram for explaining the grouping of each song name and the display time of each song name for the song names in the content list of FIG. The song names “AAAAAA...” And “ABABA...” Are set to groups of only one song because there is no other song name with the same first three characters, and as a result, “AAAAAA. ”And“ ABABA... ”Are each determined to be 100 msec. The song names “ACAAD...” To “ACAFG...” Whose content numbers are 3 to 6 are all classified into the same group because the first three characters are “ACA”. As a result, the display time of the entire group of these four music titles is set to 100 msec, so the display time of each music title is determined as 100 msec ÷ 4 music = 25 msec. Similarly, the display times of the song titles “AEAAA...” And “AEAVV...” Whose content numbers are 8 to 9 are each determined to be 50 msec.

  When the display of each song name is scrolled in the display time as shown in FIG. 4, the total display time of the song names of the content numbers 1 to 10 is 600 msec, and when the display time of all the song names is 100 msec as in the conventional case, the total is displayed. Since the display time is 1000 msec, the scroll time can be shortened compared to the conventional case. Further, when the total display time is set to 600 msec by the conventional method, the display time of each song name is 60 msec, so that the character string of the song name cannot be sufficiently recognized. On the other hand, in this example, when the title display is scrolled at a high speed of less than 100 msec, the character string of the three characters from the beginning is not changed, so that the user can fully recognize the character string of the three characters from the beginning. . That is, the user fully recognizes that the first three characters of the song title are scrolled in order of “AAA”, “ABA”, “ACA”, “ADA”, “AEA”, “AFG” every 100 msec. And scrolling can be stopped near the desired song title.

As shown in FIG. 7, the RAM 302 has an area for storing a display content number, a display content name, a display time, the number of continuous display contents, a confirmation character string, and a confirmation content number.

  The microcomputer processing unit 301 controls the overall operation of the charging apparatus 300 by executing a program stored in a ROM (not shown). The reproduction control unit 201A instructs the portable player 11 to reproduce the selected song data. The selection unit 301B selects one song name from the content list of FIG. 2 according to a user operation. The display time calculation unit 301C calculates the display time of each song name when scrolling each song name in the content list of FIG. The display control unit 301D causes the display unit 307 to display the song name stored in the display content name shown in FIG. 7 from the song names in the content list of FIG.

  The communication circuit 303 transfers information and commands between the microcomputer processing unit 301 and the connection connector 304. The connection connector 304 is connected to the connection connector 204 of the portable player 11, and the corresponding terminals 204A to 204D and 304A to 304D are connected to each other.

The power supply circuit 306 supplies a power supply voltage to the portable player 11 via the charging terminal 304B. As described above, the display unit 307 displays one piece of content information (song title) selected from the content list of FIG. 2, and is, for example, an LCD or an FL tube. An audio signal is input from the portable player 11 to the audio input terminal 304D. The audio output terminal 309 outputs the audio signal from the audio input terminal 304D to the amplifying device 13.

  Next, the operation of the present embodiment will be described with reference to the flowcharts of FIGS. Here, the scroll display when the DOWN button is pressed by a user operation will be described as an example, but the same applies to the scroll display when the UP button is pressed.

  First, a case will be described in which the DOWN button is kept pressed while the first song name (AAAAA ...) in the content list of FIG. 2 is displayed. When the DOWN button is pressed (YES in S1), the microcomputer processing unit 301 increases the value of the display content number by 1 (S2) as shown in FIG. Change to number 2. It is determined that the display content number does not exceed the total content number N in the content list (NO in S3), and it is determined whether or not the value of the continuous display content number in FIG. 7A is 1 or more (S5). . Here, since the value of the number of continuous display contents is 0 (NO in S5), the microcomputer processing unit 301 selects the song name (ABABA...) Corresponding to the display content number (No. 2) from the content list. The character string “ABA” corresponding to the number of the first three characters is read and stored in the confirmation character string as shown in FIG. 7A (S6).

  Subsequently, the microcomputer processing unit 301 sets the value of the number of continuous display contents to 1 as shown in FIG. 7A (S7). Next, the microcomputer processing unit 301 stores the number (No. 3) obtained by adding 1 to the value of the display content number in the confirmation content number of FIG. 7A (S8). It is determined that the confirmation content number does not exceed the total content number (NO in S9), and the microcomputer processing unit 301 reads the song name (ACAAD...) Corresponding to the confirmation content number from the content list, and a character string for the first three characters. Is matched with the character string stored in the confirmation character string (S10, S11). Here, the first three characters of the song name corresponding to the confirmation content number are “ACA”, which is different from the confirmation character string “ABA” (NO in S11), so the microcomputer processing unit 301 is 100 msec ÷ the number of continuously displayed contents. Value = display time is calculated, and the calculated display time is stored in the display time as shown in FIG. 7A (S16). Here, since the value of the number of continuous display contents is one, the display time is determined to be 100 msec.

  Subsequently, the microcomputer processing unit 301 reads the song name (ABABA...) Corresponding to the display content number (No. 2) from the content list and stores it in the display content name as shown in FIG. 7A (S17). . Next, the microcomputer processing unit 301 causes the display unit 307 to display the song name (ABABA...) Stored in the display content name for the display time (100 msec) (S18). Subsequently, the microcomputer processing unit 301 decreases the value of the number of continuous display contents by 1 to 0 (S19).

  If the DOWN button is continuously pressed by the user operation while the title number 2 (ABABA...) Is displayed (YES in S1), the next time immediately before the end of the display time of 100 msec, The calculation processing of the display time of the song name of the content number is executed. That is, as shown in FIG. 7B, the microcomputer processing unit 301 increases the value of the display content number by 1 and changes it to 3 (S2). Since it is determined that the display content number does not exceed the total content number N (NO in S3) and the continuous display content number is determined to be 0 (NO in S5), the microcomputer processing unit 301 displays the display content number (3 The song name (ACAAD...) Corresponding to No. is read from the content list, and the first three characters “ACA” are stored in the confirmation character string as shown in FIG. 7B (S6).

  Subsequently, as shown in FIG. 7B, the microcomputer processing unit 301 sets the continuous display content number to 1 (S7), and adds a value (number 4) obtained by adding 1 to the display content number value to the confirmation content number. (S8). It is determined that the confirmation content number does not exceed the total content number N (NO in S9), and the microcomputer processing unit 301 reads the song name (ACADD ...) corresponding to the confirmation content number (No. 4) from the content list, It is determined whether or not the first three characters (ACA) match the confirmation character string (S10, S11). Here, since they match (YES in S11), the microcomputer processing unit 301 increases the value of the confirmation content number by 1 to 5 as shown in FIG. 7C (S12), and sets the value of the number of continuously displayed contents. Increase by 1 to 2 (S13).

  It is determined that the confirmation content number does not exceed the total content number N (NO in S14), and the microcomputer processing unit 301 determines whether or not the continuous display content number exceeds the upper limit value P. The upper limit value P is the maximum number of music titles to be displayed in 100 msec, and is predetermined, for example, ten. The upper limit is set when, for example, more than 10 song names are set in one group, the display time of one song name in the group is less than 10 msec, and the song name display is scrolled. This is because it becomes difficult.

  Here, since the number of continuously displayed contents is two and does not exceed the upper limit value P (NO in S15), the process returns to S10. The processing of S10 to S15 is repeated, and it is similarly determined that the first three character strings (ACA) match the confirmation character string for confirmation content numbers 5 (ACAEF...) And 6 (ACAFG...). (YES in S11). As a result, as shown in FIG. 7D, the microcomputer processing unit 301 sets the value of the confirmation content number to 7 and sets the number of continuous display contents to 4 (S13).

  Thereafter, in S11, it is determined that the first three character strings (ADA) of the song name (ADAAA ...) corresponding to the confirmation content number 7 do not match the confirmation character string (ACA) (NO in S11). , The microcomputer processing unit 301 calculates 100 msec ÷ continuous display content number (4) = display time (25 msec) and stores it in the display time as shown in FIG. 7D (S17).

  Subsequently, the microcomputer processing unit 301 reads the song name (ACAAD...) Corresponding to the display content number (No. 3) from the content list and stores it in the display content name as shown in FIG. 7D (S17). ). Next, the microcomputer processing unit 301 causes the display unit 307 to display the song name (ACAAD...) Stored in the display content name for the display time (25 msec) (S18). Subsequently, the microcomputer processing unit 301 decreases the value of the number of continuous display contents by 1, and sets it to 3 here (S19).

  Next, when the DOWN button is continuously pressed by the user operation while the song number (ACAAD...) Whose content number is 3 is displayed (YES in S1), immediately before the end of the display time of 25 msec. Then, the calculation process of the display time of the song name of the next content number is executed. That is, the microcomputer processing unit 301 increments the value of the display content number by 1 as shown in FIG. Since the display content number does not exceed the total content number N (NO in S3) and it is determined that the continuous display content number is 1 or more (YES in S5), S6-S16 are skipped and the process proceeds to S17. . That is, as long as the number of continuously displayed contents is 1 or more, the song name belongs to the same group as the song name of the previous content number, so the display time has already been calculated, and the calculation of the display time is unnecessary.

  Therefore, the microcomputer processing unit 301 reads the song name (ACADD...) Corresponding to the display content number (No. 4) from the content list and stores it in the display content name as shown in FIG. Next, the microcomputer processing unit 301 causes the display unit 307 to display the song name (ACADD...) Stored in the display content name for the display time (25 msec) (S18). Subsequently, the microcomputer processing unit 301 decreases the value of the number of continuous display contents by 1, and sets it to 2 here (S19).

  Similarly, when the DOWN button is continuously pressed, the music numbers of content numbers 5 and 6 are also displayed on the display unit 307 in 25 msec seconds. As a result, the music titles with content numbers 3 to 6 are all displayed for 25 msec for a total of 100 msec.

  After displaying the title of the content number 6 in S18, the value of the continuous display content number is decreased by 1 and becomes 0. As a result, if the DOWN button is kept pressed, the process returns to S1 to determine the display time of the title of the song whose content number is No. 7, as in the case of the title of the song whose content number is No. 2, NO in S5. Therefore, without skipping S6 to S16, the number of music titles in the group (the number of continuous display contents) is counted to calculate the display time.

  As described above, the number of song titles having the same first three character strings (the number of continuous display contents) is counted, and the display time of the song names in the group is reduced by dividing the number of continuous display contents by 100 msec. calculate. As a result, a group of music titles having the same first three character strings can be set as one group, and the total display time of the music titles in the group can be set to 100 msec.

  When the display content number exceeds the total content number N in S3 (YES in S3), the microcomputer processing unit 301 sets the display content number to 1 indicating the first song name in the content list (S4). That is, after displaying up to the last song name in the content list, the display returns to the first song name in the content list.

  If the confirmation content number exceeds the total content number N in S9 (YES in S9), the counting of the number of continuous display contents is finished, and the process proceeds to S16, where the display time of the song title is based on the current number of continuous display contents. Is calculated. Even if the confirmation content number is returned to the first song name in the content list, the character string for three characters from the beginning of the first song name is always different from the confirmation character string, so the processing of S10 and S11 is useless. Because it becomes. Therefore, the processing can be speeded up by not proceeding to S10 and thereafter. The same applies to S14.

  In S1, when the DOWN button is released (NO in S1), the microcomputer processing unit 301 displays the song name stored in the display content name on the display unit 307 (S20), and sets the number of continuous display contents to 0. (S21).

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. The same applies when the UP button is kept pressed instead of the DOWN button. Processing in this case is shown in FIGS. Moreover, you may make it calculate the time which displays a song name for every song name in a group. The content information display device described above is not limited to being applied to the charging device 12 of the portable player 11, and may be applied to the portable player 11 and the amplification device 13. Further, the content information display device described above may be applied to a client device that acquires content from a server via a network such as a LAN and plays it back, and a controller device that controls the client device. That is, the content information device described above can be applied to any device that selects content. The present invention may also be provided in the form of a computer program for operating the content information display device or a recording medium recording the computer program.

  The present invention can be suitably applied to a content information display device that displays content information of a portable player.
