Figure 1 is a diagram showing the system configuration of this embodiment. In this embodiment, the system allows karaoke to be performed between mobile terminals 6, and therefore communication between the mobile terminals 6 is necessary. Figure 1 shows various examples of communication formats between the mobile terminals 6. For example, in the case of a private home, a router 12a connected to the Internet is provided, and a wireless router 12b is connected to the router 12a. The mobile terminal 6 can be connected to the Internet via the wireless router 12b.

In addition to these communication formats, it is also possible to communicate with the Internet using a mobile communication network. The mobile communication network is a communication format in which the mobile terminal 6 is connected to the Internet by performing wireless communication between the mobile terminal 6 and a wireless base station 13.

By using these various communication methods, the mobile terminal 6 can be connected to the Internet. A management server 11 for managing the karaoke system is also connected to the Internet. A karaoke program is installed on the mobile terminal 6 that is connected to the Internet, and by communicating with the management server 11, karaoke can be performed between the mobile terminals 6.

In the above, in this embodiment, a form in which karaoke is performed using a mobile terminal 6 as a terminal device is described. Note that, in addition to the mobile terminal 6, a home game machine, a personal computer, or a karaoke device dedicated to karaoke may also be used as the terminal device. Furthermore, a terminal device in which a karaoke program is installed will function as a karaoke device.

Fig. 2 is a diagram showing the appearance (front view) of a mobile terminal 6 according to an embodiment of the present invention, and Fig. 3 is a block diagram showing the configuration of the mobile terminal 6 according to an embodiment of the present invention. This mobile terminal 6 can be a smartphone, a tablet terminal, a mobile phone, or the like. By installing a karaoke program in this mobile terminal 6, it becomes possible to perform karaoke between mobile terminals 6.

The portable terminal 6 of this embodiment has a control means including a CPU 61, a RAM 62, a storage unit 63, an image processing unit 64, and an audio processing unit 66. The storage unit 63 can be a non-volatile storage means such as a NAND type flash memory. The program of this embodiment and various data used by the program are stored in this storage unit 63.

The CPU 61 is a means for controlling the entire mobile terminal 6, and executes various controls based on the programs and data stored in the memory unit 63. The RAM 62 temporarily stores data generated under the control of the CPU 61.

The audio processing unit 66 is a means for inputting and outputting audio related information for the mobile terminal 6. It is a means for emitting sound from the speaker 67a under the control of the CPU 61. The audio processing unit 66 is also connected to the microphone 67b, and can pick up telephone conversation voice and surrounding sounds from the microphone 67b. External devices such as a headset may be used for the speaker 67a and microphone 67b.

The touch panel display unit 68 is composed of a display unit 68m that displays an image and a touch panel 68n that is arranged on the front or back of the display unit 68m. The touch panel 68n can be of various types that can recognize the position of the user's touch, such as a capacitance type. The CPU 61 displays on the display unit 68m and can determine which part of the displayed image has been touched by touch input from the touch panel 68n.

The image processing unit 64 is a means for inputting and outputting image-related data for the mobile terminal 6. The image processing unit 64 displays and outputs images formed by the CPU 61 on the display unit 68m. It also has a function of capturing images, or video (if video), from the front camera 65F arranged on the front side (the touch panel display unit 68 side) of the mobile terminal 6, or the rear camera 65R arranged on the rear side of the mobile terminal 6, and storing the captured images or video in the memory unit 63 as image or video information.

The mobile terminal 6 of this embodiment includes a first communication unit 69a and a second communication unit 69b as communication means for communicating with the outside. The first communication unit 69a is a communication means for connecting to a mobile communication network, and by wirelessly connecting to a mobile base station 140, it is possible to perform various communications via the Internet network using the communication lines of the mobile communication network. The second communication unit 69b is a communication means for connecting via Wi-Fi. The mobile terminal 6 can use the second communication unit 69b to wirelessly connect to an access point 110 and communicate with a local area network in which the access point 110 participates. Note that, in addition to the first communication unit 69a and the second communication unit 69b, the communication means of the mobile terminal 6 may include an infrared communication unit, a short-range communication means such as Bluetooth (registered trademark), and the like.

The mobile terminal 6 of this embodiment is configured to include an input switch 70 in addition to the touch panel 68n as an input means. This input switch 70 (input switches 70a, 70b, etc. in FIG. 2) can be provided with various switches such as a power switch, a volume adjustment switch, and a switch whose input purpose is changed depending on the program.

Furthermore, the mobile terminal 6 of this embodiment has a vibration unit 72 and an LED 73 to provide various notifications to the user who holds the mobile terminal 6. The vibration unit 72 is a member formed by attaching an eccentric weight to the shaft of a motor. By driving the motor to rotate, it is possible to transmit vibrations that can notify the user. The LED 73 is located above the front of the mobile terminal 6 as shown in FIG. 2, and can provide various notifications to the user by blinking.

In this embodiment, by installing a karaoke program on such a mobile terminal 6, it becomes possible to perform karaoke between mobile terminals 6. Now, we will explain the details of the various processes that are performed when performing karaoke using a mobile terminal 6.

Figure 4 is a flow diagram showing the room processing of this embodiment. Here, a case where karaoke is performed using mobile terminals 6a and 6b will be described. In this embodiment, by gathering in a virtually created room, users in the same room can perform karaoke by sharing audio (which may also include video).

Here, we will explain the case where a user using mobile terminal 6a creates a room, and a user using mobile terminal 6b participates in that room. It is assumed that the users using mobile terminals 6a and 6b already have accounts on the management server 11. Note that users who do not have an account can access the management server 11 and create a new account.

First, the mobile terminal 6a issues a login instruction (S11) to the management server 11. The login instruction is issued by inputting account information (user ID, password, etc.). Upon receiving the login instruction (S11), the management server 11 executes a login process (S21). In the login process, authentication is performed based on the account information, and if the authentication is correct, the user is allowed to use various functions of the karaoke program.

Figure 7 (A) shows the room selection screen that is displayed after logging in. The room selection screen displays a room selection field 68a and a create new room button 68b. The room selection field 68a is a room that has already been created, and displays the status of that room. The room selection field displays the room name, icons of users participating in the room, the room's holding status ("OPEN", "In preparation"), the date the room will be held, etc. Also, a lock symbol displayed in the upper left corner of the room selection field 68a indicates that the room requires a password or that only users who have been invited in advance can participate in the room.

A user can participate in a room by operating the room selection field 68a. The new room creation button 68b is a button for creating a new room. By operating the new room creation button 68b, the mobile terminal 6a can issue a room creation instruction (S12) to the management server 11. The management server 11 executes a room creation process (S22) based on the room creation instruction (S12). When the room creation process (S22) is completed, the room selection field 68a shown in FIG. 7 (A) is displayed.

On the other hand, mobile terminal 6b that wants to join the room first issues a login instruction (S11) to management server 11 by inputting account information. As with mobile terminal 6a, management server 11 performs authentication based on the account information, and if the authentication is correct, allows mobile terminal 6b to log in. The user refers to the room selection screen shown in FIG. 7(A) and issues a room participation instruction by selecting the room selection field 68a that the user wants to enter (S13). In the example of FIG. 4, when the user of mobile terminal 6a is participating in a room created by the user, management server 11 executes a user addition process (S23) that allows the user of mobile terminal 6b to participate in the room created by the user of mobile terminal 6a.

When the users of mobile terminals 6a and 6b enter the same room, it becomes possible to execute karaoke processing (S12) between mobile terminals 6a and 6b.

The karaoke process (S12) mainly includes a reservation process and a song playback process. The reservation process is a process for reserving a song to be sung, and the song playback process is a process for playing songs registered in the reservation list in order based on the reservation process.

Figure 5 is a flow diagram showing the reservation process of this embodiment. In the reservation process, a song is searched for and a song to be sung is selected, allowing the song to be added to a reservation list managed by the management server 11. A user who wishes to reserve a song searches for a song using the song search screen shown in Figure 7 (B) (S101). The song search screen in Figure 7 (B) can be displayed by operating the song search button 68k shown in Figures 9 (D1), 9 (D2), and 10 (E), which will be described later.

The song search screen has a search category selection field 68c and a song selection field 68d. The search category selection field has search categories such as "Favorites," "Songs," "Artists," and "Albums." By selecting one of these search categories, the user can perform a song search according to the selected search category. The state in FIG. 7(B) is when "Songs" has been selected as the search category, and the song selection field 68d is displayed in alphabetical order.

The song selection field 68d displays an icon (such as album art), song title, and artist name for each song. When the user selects the desired song selection field 68d (S102: Yes), a song confirmation screen for that song is displayed (S103).

Figure 8 (C) is a diagram showing the song confirmation screen of this embodiment. The song confirmation screen displays a song confirmation field 68e. In the song confirmation field, for the selected song, an icon (such as album art), song name, artist name, a reservation button 68g, and a cancel button 68f are displayed. The user checks the information displayed on this song confirmation screen, and when making a reservation, operates the reservation button 68g (S104: Yes) to reserve the song. When a reservation is made, reservation information is sent to the management server 11. The reservation information includes a user ID indicating the user who made the reservation, and a song ID indicating the song. The management server 11 registers the received reservation information in a reservation list.

Figure 6 is a flow diagram showing the processing between mobile terminals in this embodiment. Here, an example is explained in which two mobile terminals 6a and 6b are in the same room. In reality, the number of mobile terminals 6 that can be in a room can be two or more.

First, the mobile terminal 6a executes a reservation process (S100) to reserve a desired song. The reservation process (S100) is as described in FIG. 5, and the mobile terminal 6a transmits reservation information to the management server 11. The management server 11, which receives the reservation information, registers the reservation information in a reservation list (S201). At this time, in this embodiment, in conjunction with the reservation operation, a system comment is displayed on all mobile terminals 6a and 6b that are in the room (S101, S151).

The management server 11 that receives the reservation information transmits a system comment to all mobile terminals 6a, 6b in the room in which the user who made the reservation is present (S202), and the mobile terminals 6a, 6b that receive the system comment display the system comment (S101, S151). Based on this configuration, it is possible for users who sing karaoke at a distance to be notified of operations related to the music playback process (in this case, the reservation process). This allows each user to know who is performing what operation, enabling smooth communication.

The management server 11 checks the reservation list (S203), and if there is a song to be played next (S204), executes the song playback process for that song, as enclosed by the dashed line in FIG. 6. In the song playback process, the user who made the reservation is first identified as the singer based on the user ID included in the reservation information (S205). Then, an instruction is given to the mobile terminal 6a used by the user identified as the singer to change to singer mode (S208). The mobile terminal 6a that has received the instruction to change changes to singer mode (S102).

On the other hand, the management server 11 identifies users other than the singer who are in the same room as the listeners, and instructs the mobile terminal 6b used by the user identified as the singer to change to listener mode (S207). The mobile terminal 6a that receives the change instruction changes to singer mode (S152).

In this embodiment, when switching between listener mode and singer mode, each mobile terminal 6 determines whether the user of the mobile terminal 6 is a singer or a listener, and displays a display based on the determination result on the touch panel display unit 68 serving as a display unit. The display format will be explained later.

Now, the singer mode and listener mode will be explained. When the mobile terminal 6 is set to the singer mode, the volume of the microphone 67b is increased sufficiently to make it easier to capture the user's singing voice. When the mobile terminal 6 is set to the singer mode, the singing voice captured by the microphone 67b is transmitted to the network (such as the management server 11) without adding any sound effects such as echo. When the mobile terminal 6 is set to the singer mode, a communication mode with lower latency is set than the communication processing in the listener mode. By setting this communication mode, the singing voice in the singer mode is transmitted to other mobile terminals 6 with reduced delay.

On the other hand, in a portable terminal 6 set to the listener mode, the microphone 67b is turned off or the volume of the microphone 67b is lowered so as not to interfere with the singing. In addition, the sound processor 66 adds sound effects to the singing voice transmitted via the network and the sound is emitted from the speaker 67a. Note that music is played on both the portable terminal 6 set to the singer mode and the listener mode.

In this way, by adjusting the volume in the singer mode and listener mode, it is possible to create an environment that is easy to listen to. In addition, by adding sound effects to the singing voice using the sound processing unit 66 of the mobile terminal 6 set to the listener mode, it is possible to obtain the following effects.

When transmitting audio over a network, if there is a problem with the acoustic environment that causes a delay in the singer's voice, it is possible that communication between the singer and the listener will not go well. Furthermore, when a singing voice to which sound effects (especially delay-type sound effects such as echo, delay, and reverb) have been applied is transmitted over a network, the singing voice may be significantly degraded. In this embodiment, by applying sound effects to the singing voice by the sound processing unit 66 of the mobile terminal 6 set to the listener mode, it is possible to reproduce high-quality singing voice and provide a good acoustic environment on the mobile terminal 6 set to the listener mode.

Returning to the flow diagram of FIG. 6, once the settings for the singer mode and listener mode are complete, the management server 11 starts transmitting music to each of the mobile terminals 6a, 6b (S208). In this embodiment, music is transmitted by streaming playback, but it is also possible to use an accumulation type in which music information is stored in advance in the mobile terminals 6a, 6b and then played back. In either case, music playback is synchronized on each of the mobile terminals 6a, 6b.

The music is played on each of the mobile terminals 6a and 6b (S103, S153). Then, on the mobile terminal 6a set to singer mode, the singing voice is collected by the microphone 67b (S104). The collected singing voice is sent to the management server 11, which then transfers it to the other mobile terminal 6b in the same room (S209). The mobile terminal 6b that receives the singing voice applies sound effects to the received singing voice in the sound processing unit 66 (S154), and emits it from the speaker 67a together with the music playback sound.

Figures 9 and 10 show music playback screens that are displayed during music playback on the mobile terminal 6 of this embodiment. As shown in Figure 9 (D1), the room name and a music search button 68k are displayed at the top of the music playback screen. By operating the music search button 68k, the music search screen described in Figure 7 (B) is displayed, and it is possible to reserve a song.

In addition, the music playback screen is broadly divided into a music-related display section 68h, an upper display section 68i, and a lower display section 68j. The music-related display section 68h includes a lyrics display section 681 and a progress bar 682. The lyrics display section 681 displays the lyrics to be sung for the music being played. Note that the lyrics display section 681 may also display a background image. The progress bar 682 indicates the progress of music playback.

The area occupied by the upper display column 68i and the lower display column 68j can be changed. Normally, the state shown in FIG. 9 (D1) and FIG. 9 (D2) is displayed, that is, both the upper display column 68i and the lower display column 68j are displayed. When the comment tab 686, the reservation confirmation tab 687, or the remote control tab 688 provided in the lower display column 68j is operated, the lower display column 68j is displayed using the area where the upper display column 68i was displayed, as shown in FIG. 10 (E). FIG. 10 (E) shows the state where the remote control tab 688 has been operated. Operating the comment tab 686, the reservation confirmation tab 687, or the remote control tab 688 again returns to the state shown in FIG. 9 (D1) and FIG. 9 (D2).

The upper display area 68i displays a status display/selection button 683, a microphone selection button 684, and a participating user icon 685. The status display/selection button 683 is a button that indicates the status of the mobile terminal 6.

9 (D1) shows the case where the singer mode is set, and in this case, "singing" is marked. On the other hand, FIG. 9 (D2) shows the case where the listener mode is set, and "listening" is marked. In this embodiment, the status display/selection button 683 is provided with "Away", which allows the user to temporarily leave the room. The user can manually switch between "singing", "listening", and "away". In this case, when the status is switched to "singing", the setting is changed to singer mode, and when the status is switched to "listening" or "away", the setting is changed to listener mode. In this embodiment, three states can be switched, but the status may be two, singing and listening, and various display forms can be adopted.

The microphone selection button 684 can be manually operated by the user to switch the microphone 67b on and off. In this embodiment, when the mode is set to singer mode, it is automatically set to on, and when the mode is set to listener mode, it is automatically set to off. The participating user icons 685 indicate all users participating in the room. In the examples of Fig. 9 (D1) and Fig. 9 (D2), four users have participated. The user whose icon is indicated by a thick line ("JOY" in the example of Fig. 9 (D1) and "Pirori" in the example of Fig. 9 (D2)) indicates that he/she is singing (set to singer mode). Also, the icon with a speaker and a cross mark ("Monkichi" in the example of Fig. 9 (D1)) indicates that he/she is away. These display forms are merely examples, and status such as singing, listening, and away may be indicated by other display forms.

The lower display field 68j has three tabs (a comment tab 686, a reservation confirmation tab 687, and a remote control tab 688). In the state shown in Fig. 9 (D1) and Fig. 9 (D2), the comment tab 686 is selected, and a comment display field 689 and a comment input field 690 are displayed in the lower display field 68j. In addition to user comments entered by the user using the comment input field 690, the comment display field 689 displays system comments associated with operations related to music playback processing.

In FIG. 9 (D1), the comment display field 689 displays the system comment associated with the reservation process, including the user name and the reserved song/artist name. Also, FIG. 9 (D2) shows the state after FIG. 9 (D1), with the system comment and user comment displayed in chronological order in the comment display field 689. The user comment includes the user name who entered the comment and the comment text. Users can communicate smoothly by viewing these system comments and user comments.

Figure 10 (E) shows the state when the remote control tab 688 is operated. As mentioned above, the lower display column 68j is displayed by expanding it to the area where the upper display column 68i is displayed. When the remote control tab 788 is selected, the lower display column 68j displays the singer volume 691, speaker volume 692, pitch change button 693, BGM volume 694, playback position adjustment button 695, re-sing button 696, pause button 697, and stop performance button 698.

In this embodiment, the various controls and buttons displayed on this remote control tab 688 can only be operated on a mobile terminal 6 set to singer mode. On a mobile terminal 6 set to listener mode, various controls and buttons that are prohibited from being operated may be grayed out, making it visible that they are not subject to operation. In this way, in this embodiment, on a mobile terminal 6 set to listener mode, operations related to music playback are prohibited, making it possible to prevent erroneous input by the listener.

The singer volume 691 is an operator that adjusts the volume of the singing voice input from the microphone 67b of the mobile terminal 6 that is set to the singer mode. The speaker volume 692 is an operator that adjusts the volume of the singing voice input from the microphone 67b of the mobile terminal 6 that is set to the listener mode. The singer volume 691 and speaker volume 692 are set to the default state for each mode when the mobile terminal 6 is set to the singer mode or listener mode, but can only be operated from the mobile terminal 6 that is set to the singer mode.

The pitch change button 693 is a button for changing the pitch of the song being played. The BGM volume 694 is an operator for adjusting the volume of the BGM played between songs. The playback position adjustment button 695 is an operator for changing the playback position. The current playback time and total playback time are displayed to the left of the operators. The sing again button 696 can be operated to play the currently played song from the beginning. The pause button 697 is a button for temporarily pausing the currently played song. The stop performance button 698 is a button for stopping the currently played song, and when the stop performance button 698 is operated, playback processing moves to the next reserved song.

While a song is being played, a user who has been set to singer mode can use the various controls and buttons displayed on the remote control tab 688 in FIG. 10(E) to perform various setting operations related to the song playback. In the flow diagram in FIG. 6, if a setting operation is performed while a song is being played (S105: Yes), the mobile terminal 6a sends a setting change instruction to the management server 11. The management server 11 executes the setting change according to the received setting change instruction (S210).

Setting changes can be made not only by the management server 11, such as changing the pitch of a song, but also by changing settings on various mobile terminals 6a and 6b. For example, when a mobile terminal 6a set to singer mode changes the sound settings of the sound effects (echo, delay, etc.) on another mobile terminal 6b (set to listener mode), the mobile terminal 6a set to singer mode transmits sound setting information related to the sound effects to the management server 11 (S106). The management server 11 that receives the sound setting information transfers the sound setting information to the other mobile terminal 6b. The mobile terminal 6b that receives the sound setting information imparts sound effects to the singing voice signal or the played music sound based on the received sound setting information.

The management server 11 transmits (S211) a system comment based on the setting change (S210) to each of the mobile terminals 6a, 6b. On each of the mobile terminals 6a, 6b, the system comment is displayed in the comment display field 689 described in Figures 9 (D1) and 9 (D2) (S107, S155). Therefore, users participating in the room can check the operations related to the music playback process from the system comment displayed in the comment display field 689. Therefore, users participating in the room can communicate smoothly by checking the system comment.
