FIG. 2 is a diagram illustrating an example of a classification table. FIG. 6A shows a classification table in which a plurality of karaoke songs are classified by age category. FIG. 5B shows a classification table in which a plurality of karaoke songs are classified by genre category.
[0021]
In the song data of each karaoke song, a plurality of attribute information indicating the characteristics of the karaoke song is written. The plurality of pieces of information are information indicating whether this karaoke song (song data) belongs to each group in different categories. The categories include, for example, the age shown in FIG. 1A and the genre shown in FIG. 1B, as well as the original singer, season, place, etc. Each category includes the following groups, for example.
[0022]
Age (Natsumelo, Oldies, 60s, 70s, 80s, after 90)
Genre (Enka, J-pop, Western music, anime, folk, etc.)
Original singer (... all major singers ...)
Season (Spring, Summer, Autumn, Winter)
Location (sea, mountain, town, house, etc.)
Each karaoke song (music data) belongs to a group corresponding to its own attribute information in each category. It should be noted that all the music data stored in the hard disk 13 and the CD-ROM 14 need not be classified (grouped) in this classification table, and may be a part thereof. Further, the number of pieces of music data classified by the classification table of each category and the music may be different.
[0023]
In FIG. 2, the left and right song title columns are a list of songs belonging to the same group in the category. Multiple lists are arranged one above the other in the order of the related ones. For example, in the case of the age, they are arranged so that the ages are continuous, such as “Natsumelo, Oldies, 60's, 70's, 80's, 90's and beyond”. All song names belonging to each group are arranged in the left-right direction, and all groups are arranged in order from the top and bottom to form a classification table of one category. The hard disk 13 of this karaoke device stores a classification table of the above-mentioned plurality of categories. The classification table creation process may be performed by the karaoke apparatus for the karaoke songs stored in the hard disk 13 and the CD-ROM 14, and is created in advance on the distribution center side, which is used for downloading song data, etc. You may make it download together with an opportunity.
[0024]
In addition, although each column of the classification table in the figure shows a song name, each column also includes information such as a song number for identifying the song and searching for song data in addition to the song name. It shall be remembered.
[0025]
When a normal music selection in which the music number is input from the remote controller by the user is performed, the karaoke apparatus plays only the music, but in the continuous automatic performance mode, the karaoke music is continuously played based on the classification table. When the user turns on the enter key 30 of the remote controller while playing a karaoke song in the normal mode, the mode is shifted to the continuous automatic performance mode. At this time, a classification table of predetermined categories (for example, set by default) is read, and the music of the group being played at that time is reproduced in order.
[0026]
At this time, a part of the classification table is simultaneously displayed on the monitor in the form as shown in FIG. This figure shows a state in which the age category is selected and the song “Windless” is being played. When the “Windless” song ends, the song automatically advances to the “Long time no see” song, but when the user turns on the right key (→) 31 in the middle of the “Windless” song, Stop the performance of “Stand Down” and jump to the next song “Long Time”. Also, if the user turns on the left key (←) 32 in the middle of the song “Windless”, the performance of “Windless” will be stopped, jump to the beginning of this song, and then the left key ( ←) When 32 is turned on, it jumps to the song “Sneaker Blues” which is the previous song. As described above, the left and right keys 31 and 32 are key switches used for selecting music by jumping within the same group.
[0027]
Also, when the up key (↑) 33 is turned on, the song (currently not playing) is stopped at that time, jumping to the upper group, and when the lower key (↓) 34 is turned on, the song is played at that time. Stop the current song and jump to the group below. When the “Windless” song is being played, if the up and down keys 33 and 34 are turned on, it jumps to the “Memory Glass” or “wild world” song at the corresponding position in the upper and lower groups. Play a song. After that, the songs of this group will be played in the order of the list.
[0028]
Further, when the user turns on the enter key 30 during the automatic continuous performance mode, the category of the classification table used for continuous performance is changed, and a new classification table is read out. For example, each time the enter key 30 is turned on, the category is switched in the order of “age → genre → original singer → season → location → age →”. Even if the enter key 30 is turned on and the category (classification table) is changed from the era to the genre, the tune to be played is the same song “Kazenaru”, but the categorization has been changed to that based on the genre, The group to which “Wind Standing” belongs is pop.
FIG. 3 is a screen during the performance of a karaoke song, in which a lyrics telop is synthesized and displayed on the background video, and a classification table is further displayed in OSD.
[0029]
Also, the disc (DVD) set in the BGV changer 15 is a disc on which BGV (background video) corresponding to each karaoke song is individually recorded, and does not correspond to each karaoke song individually and corresponds to various genres 30. It contains a disc that has recorded many images of about 2 seconds. In the normal mode, when playing one song at a time according to the user's selection of music, it is preferable to boost the atmosphere of the song by playing the corresponding BGV individually. However, in the automatic continuous performance mode, there are songs that are not preferred by the user. Since it is considered that a jump operation is frequently performed to the next song or the next group song when played, it is difficult to read and reproduce individual background images corresponding to each karaoke song.
[0030]
Therefore, in this karaoke apparatus, in the automatic continuous performance mode, as shown in FIG. 4, a disc on which a 30-second video is recorded is set in each of the three drives, and videos of different genres are alternately played on each drive. By doing this, it is possible to respond immediately even if a song jumps suddenly without repeating the same video.
[0031]
FIG. 5 is a flowchart showing the operation in the automatic continuous performance mode of the present invention. In this flowchart, when the automatic continuous performance mode is started, the first music to be played first is selected (s1). This music selection may be performed randomly, or only the first music may be selected by the user by a normal music selection operation (an operation for finding a music number in the table of contents and making a reservation with the remote controller). In this embodiment, when the enter key 30 is turned on while performing the karaoke performance in the normal mode, the tune is set as the first tune and the automatic continuous performance mode is entered. Next, the category of the classification table displayed on the monitor is selected (s2). That is, as shown in FIG. 3, the monitor displays the preceding and following songs and the songs in the adjacent (up and down) groups centered on the selected song. Select whether or not to display the songs in the upper and lower groups. This selection may be selected at random or may be selected by the user. Also, the mode when this mode starts may be determined by default (for example, age).
[0032]
When a category is selected, the category classification table is read (s3), and a list of groups to which the first song selected in s1 belongs is read from the category table (s4). This list may be read out for several songs around the first song. Next, in the list of groups above and below the group to which the selected song belongs, a location corresponding to the location read in s4 is read (s5). These are displayed on the monitor as shown in FIG. 3 (s6).
[0033]
A list of songs is displayed on the monitor in the above process, and the selected song data is read from the hard disk 13 (s7) and input to the sound source 16 to execute a performance process (s8). While playing this song, it is monitored whether the song is finished (s10) or whether the user performs a remote control operation (s11, s12, s13). If the user does not perform any operation, the karaoke apparatus performs the entire chorus performance of this karaoke song. When the song ends (s10), the next song in the list of the same group is selected (s14), the song at the end of the list is read so that this song is at the center, and the list display is updated (s15). After this, the process proceeds to s7 to start the newly selected performance.
[0034]
On the other hand, when the left and right keys 31 and 32 are operated during the performance of the karaoke song (s11), the previous or next song is selected according to the operated key (s16). That is, when the right key 31 is turned on, the next song in the same group as the currently playing song (the song displayed on the right) is selected. When the left key 32 is turned on, the previous song (song displayed on the left) in the same group as the currently playing song is selected. Then, the list display is updated by reading out the previous or previous song in the list so that the selected song becomes the center of the list (s17). After this, the process proceeds to s7 to start the newly selected performance.
[0035]
If the up / down keys 33 and 34 are operated during the performance of the karaoke song (s12), the song moves to the upper or lower group according to the operated key and corresponds to the karaoke song currently being played. Is selected (s18). That is, when the up key 33 is turned on, the group moves to the group displayed above the currently playing group, and the song corresponding to the currently playing song (displayed immediately above the currently playing song). Song). When the down key 34 is turned on, the group moves to the group displayed below the currently playing group, and the song corresponding to the currently playing song (the song displayed directly below the currently playing song). ). In response to this music selection, when moving up, it reads the list of the upper group, and when moving down, it reads the list of the lower group and displays the list on the monitor. Is updated (s19). After this, the process proceeds to s7 to start the newly selected performance.
[0036]
On the other hand, when the enter key 30 is pressed during the performance of the karaoke song (s13), the category of the list displayed on the monitor is changed without changing the song to be played (song selection). That is, the next category is selected in the order as described above (age → genre → original singer → season → place) (s20), and the category classification table is read (s21). A list of groups to which the currently playing music belongs is read from this classification table (s22). The reading of this list may be performed for several songs before and after the song being played as in the case of s4. Next, in the list of groups above and below the group to which the selected song belongs, a location corresponding to the location read in s22 is read (s23). These lists are displayed on the monitor as shown in FIG. 3 (s24). After that, in order to continue the performance of the currently playing song, the process returns to the standby routine of s10 or less.
[0037]
Thus, in this embodiment, karaoke music is classified into a plurality of groups, and the music of the group to which the selected music belongs is sequentially played automatically, so that the music that suits the user's preference is played continuously. be able to. In addition, by providing a forward / backward key for jumping music selection back and forth within the same group, if there is an unfavorable song in the group, the previous key is operated to skip that song and advance to the next song If the same song is repeated or the previous song is returned, the rear key may be operated. Further, if the up / down key is operated, the group moves to another group, so that the song can be freely selected around the currently playing song.
[0038]
In addition, a classification table in which karaoke songs are classified into a plurality of groups as described above and created as a table is created for a plurality of categories, and is used for music selection (displayed on the monitor) when the enter key is turned on. By changing the category, it is possible to continuously play a list classified by various cuts (categories) around a favorite song.
[0039]
In addition, a log of performance songs (category name, group name, song name) by this classification table is recorded and classified based on the order of songs played, jumped songs, history of movement between groups and categories, etc. The table may be updated. For example, it is possible to create a classification table that is easier to sing by adding or subtracting the songs in the group or changing the song arrangement based on the order of the played songs or the jumped songs. In addition, by rearranging categories and groups based on the movement history between groups and between categories, it is possible to create a classification table that is easier for singers to use.
[0040]
Further, the distribution center sucks up and collects performance logs of a plurality of karaoke apparatuses, updates the classification table based on the performance logs, and redistributes the updated classification table to each karaoke apparatus. With the device, it is possible to perform continuously with a classification table that better suits the singer.
[0041]
【The invention's effect】
As described above, according to the present invention, a user can continuously perform a karaoke song on the karaoke device continuously, and if the group of karaoke songs to be continuously played is his / her preference, the user can continue it. You can search for your favorite group by changing the group or changing the grouping (category) itself for groups that you do not like. Also, even if you are in a favorite group, there are songs that you don't like, but in this case you can skip (jump forward) that song, and repeat the same song in the same group, It is also possible to go back. This eliminates the burden of selecting a karaoke song that the user wants to sing, and allows the user to efficiently search for a favorite group of songs.
