Description

  The present invention relates to a content information display device that acquires and displays content information from a server and a program thereof.

  2. Description of the Related Art A system including a server that records content such as a music file and a terminal device that is connected to the server via a network and acquires content from the server and plays it back is used. When the user operates the terminal device to select desired content to be played back on the terminal device from among a plurality of contents recorded on the server, a song list is displayed on the display unit of the terminal device. The song list is a list of song names of a plurality of song files. When the terminal device requests the song list from the server, the song list is acquired from the server. When a cursor is displayed on a desired song name in the song list by a user operation and a reproduction instruction is input, the song file on which the cursor is displayed is acquired from the server and reproduced. When the screen size of the display unit of the terminal device is small, for example, only 10 song titles can be displayed at a time in the song list displayed on the display unit. The song list displayed at one time is a one-page song list.

  When the terminal device displays the song list of the first page (1 to 10 songs), the terminal device requests the song names of the 1 to 10 songs from the server, the server returns the song names of the 1 to 10 songs, and the terminal The apparatus acquires this and displays it as a song list (for example, Patent Document 1 below). Here, when the page advance button is operated by the user operation, the display is changed from the currently displayed song list on the first page to the song list on the second page. At this time, the terminal device requests the names of the 11th to 20th songs included in the song list on the second page to the server, the server returns the names of the 11th to 20th songs, and the terminal device obtains this to obtain the song list. Display as. In this way, each time the page advance button is operated by a user operation, the server requests and acquires the song names for the number of displayed song lists on the next page. However, it takes a certain amount of time to acquire the names of the songs in the song list from the server via the network. Therefore, when a large number of song files are recorded on the server, when the song list page needs to be advanced many times by user operation, the transmission / reception of the song name between the terminal device and the server advances the user's page. There is a problem that it takes a long time until the desired song name is displayed in the song list without keeping up with the operation speed of the buttons.

  Similarly, when the cursor advance button is operated by a user operation, the cursor moves to the next song name. At this time, the song list page may be changed to the next page. Even when the song list is changed to the song list on the next page, it is necessary to acquire the number of song names displayed from the server via the network, so it takes time to display the song list. There's a problem.

  When the page advance button or the cursor advance button is continuously operated by a user operation, the music list can be displayed quickly.

  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 terminal device 1 and a server 11 to which a content information display device according to a preferred embodiment of the present invention is applied. The terminal device 1 and the server 11 are connected to each other via an arbitrary network such as the Internet or a LAN. The server 11 records a plurality of contents. The content is a general term for music data (music file), video data, image data, and the like, but in this example, it is a music file. The terminal device 1 receives desired content from the server, for example, in a streaming format, and reproduces the received content. Further, the terminal device 1 requests and acquires content information of a plurality of contents from the server, and displays a content list in which the content information is listed (hereinafter referred to as a song list). The content information is metadata such as a song name (title), artist name, album name, and genre name of the song file. In this example, the content information will be described.

  The terminal device 1 includes a control unit 2, a memory (ROM, RAM, etc.) 3, a reproduction unit 4, an amplification unit 5, an operation unit 6, a display unit 7, and a communication unit 8.

  The control unit 2 controls the entire terminal device 1 based on an operation program of the terminal device 1 such as a content information display program stored in the memory 3, and is, for example, a microcomputer or a CPU.

  The control unit 2 requests the song list from the server 11, receives the song list returned from the server 11, and causes the display unit 7 to display the song list. The song list includes a predetermined number of song names that can be displayed on the display unit 7 among the song names of a plurality of song files recorded in the server 11. As shown in FIG. 2 (FIGS. 2A to 2G), the display unit 7 can display a song list including, for example, 10 song names. A song list that includes a predetermined number of song names and can be displayed on the display unit 7 at a time is called a one-page song list. As shown in FIG. 2, “Song number (track number) of the music file at which the cursor is currently displayed / Total number of music files recorded in the server 11” is displayed in the upper right part of the music list. Note that, when searching by narrowing down music files by category such as artist name, “total number of music files to which the selected artist name is assigned” instead of “total number of music files recorded in the server 11”. "

  For example, referring to FIG. 2A, “3/2000” is displayed, 2000 music files are recorded in the server 11, and the cursor is displayed on the music name of the music file with the music number 3 among them. It means that The song list in FIG. 2A is a song list on the first page, and includes the song names (a01 to a10) of ten song files having song numbers 1 to 10. In this example, for convenience of explanation, the song name of the song file is represented by “a” + song number. Similarly, FIG. 2E shows a song list on the second page, which includes the song names (a11 to a20) of ten song files with song numbers 11 to 20. FIG. 2F shows a song list on the third page, which includes the song names (a21 to a30) of the ten song files with song numbers 21 to 30. FIG. 2G shows the song list on the fourth page, which includes the song names (a31 to a40) of the ten song files with song numbers 31 to 40.

  The operation unit 6 is provided with a page advance button for advancing the song list page displayed on the display unit 7 to the next page and a page return button for returning to the previous page. When the page advance button is operated, a page advance instruction is input to the control unit 2, and when the page return button is operated, a page return instruction is input to the control unit 2. The operation unit 6 also starts playback of a cursor advance button for advancing the cursor display position in the song list, a cursor return button for returning the cursor display position, and a song file with the song name on which the cursor is displayed. And a determination button to be provided. When the cursor advance button is operated, a cursor advance instruction is input to the control unit 2, and when the cursor return button is operated, a cursor return instruction is input to the control unit 2.

  The control unit 2 transmits a song list request command to the server 11 in order to acquire the song list of each page from the server 11. The song list request command includes a request list including the song numbers of one or more song files for requesting transmission of song names from among the song numbers of a plurality of song files recorded in the server 11. For example, when all the song names in the song list in FIG. 2A are acquired, the request list includes song numbers 1 to 10. When only the third song name in the song list of FIG. 2A is acquired, only the song number 3 is included in the request list.

  In this example, when a page advance button or a page return button is continuously operated by a user operation, a song list is obtained by the following method in order to quickly obtain and display a song name from the server 11 according to the user operation. Is getting. That is, when the page advance button (or page return button) is operated, the control unit 2 requests and acquires all the 10 song names for the next (or previous) one page from the server 11 at a time. Instead, only the song name on which the cursor of the song list on the next page is displayed is first obtained from the server 11 and displayed. Thereafter, when the same page advance button (or page return button) is operated again within a predetermined time, the control unit 2 selects the remaining song names other than the song name on which the cursor of the next (or previous) page is displayed. Without obtaining from the server 11, the song name on which the cursor of the next (or further previous) page is displayed is obtained from the server 11 and displayed. Even if the remaining song name other than the song name on which the cursor of the next (or previous) page is displayed is acquired from the server 11 and displayed, the display is immediately changed to the song list of the next (or even previous) page. Therefore, it is meaningless to display these song names, and it is considered that the user does not want them.

  In addition, when the same page advance button (or page return button) is operated again within a predetermined time, the control unit 2 acquires the song name on which the cursor is displayed and acquires the next ( Alternatively, in the music list from the previous page to a predetermined number of pages ahead (or previous) (for example, 10 pages ahead), the music title on which the cursor is displayed is acquired from the server and stored in the memory 3. That is, the control unit 2 obtains the name of the song on which the cursor is displayed in the request list, and displays the cursor from the next (or) page after the page stored in the memory 3 to a predetermined number of pages ahead (or previous). Include the song number of the song name. For example, if the song name has been acquired up to the song number 23 on which the cursor on the third page is displayed, as shown in FIG. 3, the request list includes a plurality of unacquired pages from the fourth page to the thirteenth page. The song numbers 33, 43, 53, 63, 73, 83, 93, 103, and 113 of the song names on which the cursors are displayed are included. Thereafter, as shown in FIG. 4, the control unit 2 stores the song name acquired in association with the song number in the memory 3.

  When the page advance button (or page return button) is operated again, the control unit 2 confirms whether or not the song name on which the cursor of the next (or previous) page is displayed is already stored in the memory 3. If stored, the song title is read from the memory 3 and displayed without obtaining the song title from the server 11. Therefore, it is possible to quickly display the song name on which the cursor of the next (or previous) page is displayed.

  On the other hand, when the page advance button (or page return button) in the same direction is not operated again within a predetermined time, the control unit 2 displays the remaining song names other than the song name on which the cursor of the next (or previous) page is displayed. Is acquired from the server 11 and displayed. This is because it is considered that the user desires to display all song names in the song list on this page.

  As a result, when the page advance button (or page return button) is continuously operated by the user and the operation interval is within a predetermined time, the song name on which the cursor of the next (or previous) page is displayed. Only the display is changed. Further, a song name on which a cursor for a plurality of pages is displayed is acquired in advance from the server 11 and stored in the memory 3. On the other hand, if the operation interval is not within the predetermined time, the remaining song names other than the song name on which the cursor of the song list on the next (or previous) page is displayed are also acquired from the server 11 and displayed. As a result, the display of the song list can be quickly changed in response to a user operation.

  It is not the case that all the song lists on the next (or previous) page are acquired, but only the song name on which the cursor on the next (or previous) page is displayed is acquired from the server 11 and displayed. Because of the reason. The song name for which the cursor is displayed is a song name for which the terminal device 1 obtains a song file from the server 11 and starts playing when the decision button is operated by a user operation. The user cannot understand which song file is played. In addition, when the operation of the page feed button (or page return button) with the operation interval within a predetermined time is continued multiple times, if the song name displayed by the cursor is not changed, the song list to be displayed is The user cannot understand whether it is a list of surrounding songs. Therefore, when the operation interval of the page feed button (or the page return button) is within a predetermined time, it is preferable that only the song name on which the cursor is displayed is displayed because the above problem can be solved.

  Returning to FIG. 1, the playback unit 4 executes playback processing (including decompression processing, D / A conversion processing, and the like) for music files acquired from the server 11 in, for example, a streaming format. The amplifying unit 5 amplifies the music signal reproduced by the reproducing unit 4 and supplies the music signal to a speaker (not shown).

  The communication unit 8 is connected to the server 11 via the Internet or LAN, and transmits and / or receives various commands, song files, song lists (song names), and the like with the server 11. Etc.

  The server 11 includes a control unit 12, a memory 13, an HDD 14, and a communication unit 15.

  The control unit 12 controls the entire server 11 based on an operation program of the server 11 stored in the memory 13, and is a microcomputer, a CPU, or the like, for example. In response to the song list request command received from the terminal device 1, the control unit 12 generates a song list (song name) and sends it back to the terminal device 1. Further, in response to a request from the terminal device 1, the music file designated from the HDD 14 is read and transmitted to the terminal device 1.

  The HDD 14 stores a plurality of song files and content information (song titles) related to the song files. The song names of the song files are rearranged in alphabetical order and / or alphabetical order, and song numbers are assigned in that order.

  The communication unit 15 is connected to the terminal device 1 via the Internet or LAN, and transmits and / or receives various commands, song files, song lists (song names), and the like with the terminal device 1. Network interface, etc.

  Operations of the terminal device 1 and the server 11 having the above configuration will be described. FIG. 5 is a flowchart showing processing of the terminal device 1 and the server 11. Note that a case where the page of the song list is advanced to the next page, that is, a case where the page advance button is operated will be described as an example, but the same applies when returning to the previous page. In this example, it is assumed that the song list shown in FIG. 2A is initially displayed.

  The control unit 2 of the terminal device 1 determines whether an instruction to change the song list to the next page is input by a user operation, that is, whether the page advance button is operated (S1).

When the page advance button is operated (YES in S1), the control unit 2 requests the server 11 only for the song name on which the cursor is displayed in the song list on the next page (S2). Specifically, the control unit 2 calculates the song number of the song title to be acquired based on the following formula 1.
Song number of the song name to be acquired n = Cmax × (P−1) + C (Formula 1)
Here, Cmax is the number of song names that can be displayed in the song list on one page, P is the page number, and C is the position of the cursor in the song list (starting at 1, the value is incremented by 1) It is.

  In this example, the page advance button is operated when the song list on the first page (10 song names can be displayed on one page) is displayed and the cursor is displayed on the third song name from the top. Therefore, the third song name from the song list on the second page is the song name to be acquired, and the song number n of the song name to be acquired is 10 × (2-1) + 3 = 13.

  The control unit 2 generates a request list including the calculated song number of the song title to be acquired, and transmits a song list request command including the request list to the server 11. In the above example, a request list including only the song number 13 is generated and transmitted. When receiving the song list request command from the terminal device 1, the control unit 12 of the server 11 reads the song name of the song number included in the request list of the song list request command from the HDD 14 and sends it back to the terminal device 1 (S11). In this example, when the song number is 13, the song name a13 of the song file with the song number 13 is returned. When receiving the song title from the server 11, the terminal device 1 changes the song title on which the cursor is displayed to the received song title. That is, in the displayed music list, only the music name on which the cursor is displayed is changed to the next page. In this example, as shown in FIG. 2B, the song title a03 is changed to a13. In FIG. 2B (the same applies to FIGS. 2C and 2D), the song names other than the song name a13 on which the cursor is displayed are not displayed, but these may be displayed or grayed out. Good.

  In S2, the control unit 2 confirms whether or not the song name on which the cursor of the next page is displayed is saved in the memory 3, and if it is saved, reads the song name saved in the memory 3. By displaying, it is possible to display quickly.

  Subsequently, the control unit 2 starts a timer count in order to measure the operation interval of the page advance button (S3). The timer ends counting when a predetermined time (for example, 0.5 seconds) elapses. Subsequently, the control unit 2 determines whether or not the timer has ended (S4).

  When the timer count has not ended (NO in S4), the control unit 2 determines again whether or not the page advance button has been operated by the user operation (S5). If the page advance button is not operated (NO in S5), the process returns to S4. When the page advance button is operated (ie, the operation interval of the page advance button is within a predetermined time) (YES in S5), the control unit 2 selects a song other than the song name on which the cursor of the song list on the next page is displayed. Without acquiring the remaining song names, only the song names for which the cursor of the song list of the next page is displayed are displayed on the display unit 7 (S6 to S8). In this example, as shown in FIG. 2, since the song number of the song name on which the cursor is displayed is 13, the song names of the song numbers 11, 12, 14 to 20 are not acquired, and the cursor on the next page is displayed. As shown in FIG. 2C, the song name displayed on the cursor is changed from the song name a13 with the song number 13 to the song name a23 with the song number 23.

  Specifically, the control unit 2 generates a request list including the song number of the song name on which the cursor is displayed in the song list of a predetermined number of pages from the page following the page on which the song name on which the cursor is displayed has been acquired ( S6). The music numbers included in the request list are calculated by substituting the page numbers of the respective pages based on the above formula 1. In this example, since the song name a13 on which the cursor of the second page is displayed is acquired, the cursor is placed in the song list from the third page, which is the next page, to a predetermined number of pages (for example, 10 pages). The song number of the displayed song name is included. That is, as shown in FIG. 3, the request list includes song numbers 23, 33, 43, 53, 63, 73, 83, 93, 103, and 113.

  The control unit 2 transmits a song list request command including a request list to the server 11 (S7). The server 11 reads the song name corresponding to the song number included in the request list of the song list request command from the HDD 14 and sends it back to the terminal device 11 (S12). In this example, song names a23, a33, a43, a53, a63, a73, a83, a93, a103, a113 are returned. The terminal device 1 receives the song title and stores it in the memory 3 in association with the song number as shown in FIG. 4 (S7).

  Subsequently, the control unit 2 causes the display unit 7 to display a song name on which the cursor of the song list of the next page is displayed (S8). In this example, as shown in FIG. 2C, the song title a13 is changed to the song title a23. In addition, before acquiring a plurality of song names in S6 and S7, when the song name a23 on which the cursor of the song list of the next page is further stored is stored in the memory 3, the memory in parallel with the process of S6 3 is read out and displayed. Therefore, by storing in advance in the memory 3 the song names on which the cursors for a plurality of pages are displayed, it is possible to quickly display the song names on which the cursor of the song list on the next page is displayed. Note that as long as at least one song name for which the cursor is displayed is stored in the memory 3, the processing of S6 and S7 may be omitted.

  Thereafter, the controller 2 resets the timer count and starts counting the timer from the beginning (S3). This is because the operation interval until the next page advance button is operated is measured.

  In this state, before the timer count ends (NO in S4), if the page advance button is operated again (YES in S5), the song name a113 where the cursor on the 12th page is displayed is acquired. In the song list from the 13th page as the next page to a predetermined number of pages (for example, 10 pages), the song number of the song name on which the cursor is displayed is included. That is, the request list includes music numbers 123, 133, 143, 153, 163, 173, 183, 193, 203, and 213.

  The control unit 2 transmits a song list request command including a request list to the server 11 (S7). The server 11 reads the song name corresponding to the song number included in the request list of the song list request command from the HDD 14 and sends it back to the terminal device 11 (S12). In this example, song names a123, a133, a143, a153, a163, a173, a183, a193, a203, a213 are returned. The terminal device 1 receives the song title and stores it in the memory 3 in association with the song number (S7).

  The control unit 2 causes the display unit 7 to display a song name on which the cursor of the song list of the next page is displayed among the plurality of song names stored in the memory 3 (S8). In this example, as shown in FIG. 2D, the song title a23 is changed to the song title a33. Here, since the song title a33 to be displayed is stored in the memory 3 before the execution of S6 and S7, the process of S9 can be executed in parallel with the processes of S6 and S7. Accordingly, by storing in advance the song name on which a cursor of a plurality of pages is displayed in the memory 3, the song name on which the cursor is displayed can be displayed quickly.

  When it is determined in S4 that the timer count has ended (that is, the next page advance button has not been operated within a predetermined time) (YES in S4), the control unit 2 moves the cursor of the song list on the next page. The server 11 is requested for remaining song names other than the displayed song names (S9). For example, when the song list on the first page is displayed and the cursor is displayed on the third song name from the top, when the page advance button is operated and the timer count ends, as shown in FIG. 2B, Since the song name of song number 13 has already been acquired and displayed, a song list request command including a request list including the remaining song numbers 11, 12, and 14 to 20 is transmitted to the server 11. In response to the song list request command, the control unit 12 of the server 11 reads the song names of the remaining song numbers (for example, song numbers 11, 12, 14 to 20) from the HDD 14 and transmits them to the terminal device 1 (S13). .

  The terminal device 1 receives the song name of the received song number and changes the song title display in the song list (S9). For example, the titles of the remaining song numbers 11, 12, 14 to 20 are received, and the control unit 2 receives the song names a11, a12, and a14 to the received song numbers 11, 12, 14 to 20, as shown in FIG. 2E. a20 is displayed. Thereafter, the process returns to S1.

  Similarly, for example, when the timer count ends in the state shown in FIG. 2C, the song name of song number 23 has already been acquired and displayed, so a request list including the remaining song numbers 21, 22, 24-30 is displayed. A song list request command including the command is transmitted to the server 11. In response to the song list request command, the control unit 12 of the server 11 reads the song names of the remaining song numbers (for example, song numbers 21, 22, 24-30) from the HDD 14 and transmits them to the terminal device 1 (S13). .

  The terminal device 1 receives the song name of the received song number and changes the song title display in the song list (S9). Here, the remaining song titles 21, 22, 24 to 30 are received, and the control unit 2, as shown in FIG. 2F, receives the song titles 21, 22, 24 to 30, a 21, a 22, a 24. ~ A30 is displayed. Thereafter, the process returns to S1.

  As described above, when the page advance button is operated, only the song name on which the cursor of the song list of the next page is displayed is acquired from the server 11 and displayed. If an instruction to advance to the next page is input within the specified time, the remaining song name other than the song name on which the song list cursor on the next page is displayed is not acquired and the song name on which the cursor is displayed has not been acquired. From the server 11, the music title on which the cursor in the music list for a predetermined number of pages is displayed is stored in the memory 3. Then, the song name on which the cursor of the song list on the next page is displayed is displayed. Therefore, if the song name on which the cursor of the next song list is displayed is stored in the memory 3, it can be quickly displayed by reading the song name from the memory 3.

  On the other hand, if the next page advance instruction is not input within a predetermined time, the remaining music names other than the music name on which the cursor of the music list on the next page is displayed are acquired and displayed. Therefore, the display of the song name in the song list can be quickly changed according to the user operation.

  Next, another preferred embodiment of the present invention will be described. This example is processing when the cursor advance button (or cursor return button) is operated. FIG. 6 is a flowchart showing the processing of the control unit 2 of the terminal device 1 in this example. In this example, the process when the cursor advance button is operated will be described as an example, but the process when the cursor return button is operated is the same. First, as shown in FIG. 2A, it is assumed that the cursor is displayed on the song name a03.

  The control unit 2 determines whether or not a cursor advance instruction is input by operating the cursor advance button (S21). When the cursor advance instruction is input (YES in S21), the control unit 2 advances the cursor in the song list to the next song name as shown in FIG. 7A (S22). That is, the cursor is moved from the music a03 to a04. If it is necessary to change the display to the song list on the next page by advancing the cursor, it is checked whether the song name of the song list on the next page is stored in the memory 3. If the song name is stored in the memory 3 by the processing described later, the song name is read from the memory 3 and displayed. If not saved in the memory 3, the song name of the song list on the next page is acquired from the server 11. To display.

  The control unit 2 starts a timer count to measure the operation interval of the cursor advance button (S23). The timer ends counting when a predetermined time (for example, 0.5 seconds) elapses. Subsequently, the control unit 2 determines whether or not the timer has ended (S24). When the timer count is finished (YES in S24), the process returns to S21.

  If the timer count has not ended (NO in S24), the control unit 2 determines again whether or not a cursor advance instruction has been input (S25). If no cursor advance instruction is input (NO in S25), the process returns to S24.

  On the other hand, when the cursor advance instruction is input (YES in S25), that is, when the next cursor advance instruction is input within a predetermined time after the cursor advance instruction is input, the data is acquired from the server 11 and stored in the memory 3. A request list including a song number next to the song number of the saved song name to a song number ahead of a predetermined number is generated (S26). For example, when the song name a10 up to the song number a10 is acquired from the server 11 and stored in the memory 3, the song numbers corresponding to ten songs from the next song number 11 after the song number 10, that is, the song numbers 11 to 20 are A request list containing is generated.

  The control unit 2 transmits a song list request command including a request list to the server 11 (S27). In response to the song list request command, the server 11 reads the song name of the song number included in the request list from the HDD 14 and sends it back to the terminal device 1. In this example, song names a11 to a20 with song numbers 11 to 20 are returned. The control unit 2 receives the song names a11 to a20 and stores them in the memory 3 in association with the song numbers (S27).

  As shown in FIG. 7B, the control unit 2 advances the cursor of the song list to the next song title (S28). That is, the cursor is moved from the song a04 to a05. Since the song name a05 after the cursor movement is already displayed (saved in the memory 3), the process of S28 can be executed in parallel with S26 and S27.

  As described above, when the next cursor advance instruction is input within a predetermined time after the cursor advance instruction is input, a plurality of unacquired song names are acquired in advance. When the page is changed, the song list can be quickly displayed by reading the song name from the memory 3 and displaying it.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. The present invention may be provided in the form of a computer program for operating the content information display device or a recording medium on which the computer program is recorded.
