The viewer terminal includes a first display control unit 75a that causes the display unit 72 to display the singing video live-delivered by the server device S, and a second display control unit 75a that causes the display unit 72 to display the music list for voting disclosed by the server device S. A display control unit 75b, a voting unit 75c that transmits to the server device S voting information indicating a song selected by the viewer as a song that the viewer wants the singer to sing karaoke from among the songs included in the song list for voting, have The server device S includes a publishing unit 82a that publishes the voting music list received from the karaoke device K, a distribution unit 82b that performs live distribution of the singing video being streamed by the karaoke device K to viewer terminals, and a plurality of viewers. a tallying unit 82c for tallying the voting information transmitted from the terminals and stored in the storage means 80 of the server device S to calculate a voting result and transmitting the voting result to the karaoke device K;

According to such a karaoke system 1, the viewer can select a song that the viewer wants to listen to while referring to the voting song list. Therefore, even if the viewer is fluid (for example, a viewer who starts listening to the singing video in the middle), he/she can select the music that he or she wants to listen to each time. In addition, according to the karaoke system 1, the next song to be sung in karaoke (song for streaming transmission of singing video) is automatically determined by votes from viewers. Therefore, even if there are an unspecified number of viewers, songs that many viewers want to listen to are preferentially played in karaoke, and singing videos are stream-transmitted. In addition, since the singer does not have to worry about selecting songs, it becomes easier to respond to comments and the like from viewers. Furthermore, by using the karaoke machine K, it is possible to obtain singing videos with high-quality performance sounds and singing voices. That is, according to the karaoke system 1 according to the present embodiment, when a singing video is live-delivered using a karaoke device, it is possible for the viewer to easily determine the music that the viewer wants to listen to.

In addition, the karaoke device K in the karaoke system 1 according to the present embodiment instructs the tallying unit 82c to tally the voting information when the remaining performance time of the song being played in karaoke reaches a predetermined time. be able to.

Further, the counting unit 82c in the karaoke system 1 according to the present embodiment can delete the voting information stored in the storage means 80 of the server device S after counting the voting information. According to the karaoke system 1, since the voting information is deleted each time, the voting information of past viewers (viewers who are not watching at present) will not be reflected in the voting results. Therefore, even if the viewers' mobility is high, it is possible to more accurately determine the songs that the viewers who are watching at the present time want to listen to.

Also, the performance processing unit 200 in the karaoke system 1 according to the present embodiment can perform karaoke performances of all songs included in the set list. In this case, the karaoke device K can stream singing videos of all songs that the singer wishes to sing in karaoke.

<Second embodiment>
Next, a karaoke system according to the second embodiment will be described with reference to FIG. In the present embodiment, an example of streaming transmission of singing videos of some of the songs included in the set list will be described. A detailed description of the configuration similar to that of the first embodiment will be omitted.

[Performance processing section]
The performance processing unit 200 according to the present embodiment starts karaoke performance of a song based on an operation input from a singer.

Some singers want to start singing karaoke at an arbitrary timing. Alternatively, in live distribution, a video (hereinafter referred to as a talk video) that does not perform karaoke singing, such as explaining a song to be sung in karaoke or responding to comments from viewers, may be distributed. In such a case, it is desirable for the singer to be able to indicate the start timing of the karaoke performance.

Therefore, the performance processing unit 200 according to the present embodiment does not perform karaoke until there is an instruction to start performance from the singer via the remote control device 50 . The performance processing unit 200 starts karaoke performance when there is an operation input from the singer.

Acquisition and streaming transmission of talk videos can be performed in the same manner as acquisition and streaming transmission of singing videos. That is, the microphone 40 collects the voice spoken by the singer. A camera 60 takes a picture of a singer speaking and obtains a moving image. The transfer unit 300 generates a talk video by synthesizing the voice and the video, and transmits the video to the server device S by streaming.

Furthermore, the performance processing unit 200 according to the present embodiment, if the karaoke performance of the next song determined to be performed karaoke cannot be finished during the set distribution time or by the distribution end time, the next karaoke performance Do not perform karaoke performances of songs.

The delivery time is the time during which the live delivery is performed (the time during which the singing video or the like is streamed). The delivery end time is the time at which the live delivery ends (the time at which the streaming transmission of singing videos or the like is stopped). The delivery time or delivery end time can be set by the singer via remote control device 50 at any time (30 minutes, 1 hour, etc.) or at any time (15:00: 00, etc.) can be set. When setting the delivery time or the delivery end time, the singer may also set the delivery start time. Also, the delivery time or the delivery end time may be set during the live delivery (for example, when several singing videos are streamed).

For example, assume that the delivery end time set by the singer is 16:00:00, the current time is 15:55:00, and the playing time of the next song is 06:00. In this case, the delivery end time arrives while the next song is being karaoke-played (while the singing video is being streamed). In such a case, karaoke performance of the next piece of music becomes unnecessary. Therefore, the performance processing section 200 does not read out the performance data of the next piece of music from the storage means 10a. In such a case, singing videos of only some of the songs included in the set list are streamed.

==Specific example of processing in a karaoke system==
Here, the processing in the karaoke system 1 according to this embodiment will be described more specifically. In this example, it is assumed that the voting music list generation unit 100 of the karaoke machine K has generated a set list L0 including the music pieces X1 to X5. Also, the music piece X1 placed at the head of the set list L0 is set as the first music piece for karaoke performance. Also, it is assumed that the singer has previously set 12:14:00 as the delivery start time and 12:34:00 as the delivery end time. The time from the distribution start time to the distribution end time (distribution time) is set to be sufficiently longer than at least the performance time of the first song in the set list. Further, the karaoke machine K instructs the tallying unit 82c to start tallying voting information when the remaining performance time of the song being played in karaoke reaches a predetermined time. The tallying unit 82c tallies the voting information based on the instruction. Further, after counting the voting information, the totalizing section 82c deletes the voting information stored in the storage means 80 of the server device S. FIG.

When the delivery start time (12:14:00) arrives, the singer first starts Talk T1. In this case, the transfer unit 300 of the karaoke machine K generates the talk video W1 based on the voice of the talk T1 and the video image obtained by photographing the singer, and transmits it to the server device S by streaming.

The distribution unit 82b performs live distribution of the streaming-transmitted talk video W1 to the viewer terminal. A viewer views the talk video W1 via a viewer terminal.

After finishing the talk T1, the singer uses the remote control device 50 to perform an operation input to start karaoke performance. In accordance with the operation input for starting the karaoke performance, the transfer unit 300 ends the streaming transmission of the talk video W1 to the server device S. The distribution unit 82b of the server device S ends the live distribution of the talk video W1. The viewer finishes viewing the talk video W1.

The voting music list generation unit 100 updates the set list by deleting the music X1 from the set list L0, and transmits the voting music list L1 to the server device S. The voting song list L1 includes songs X2 to X5. The publishing unit 82a of the server device S publishes the voting music list L1 and starts accepting voting information.

On the other hand, based on the operation input for starting the karaoke performance, the performance processing section 200 of the karaoke device K starts the karaoke performance based on the performance data of the song X1. The singer sings karaoke along with the karaoke performance. The transfer unit 300 of the karaoke device K generates a singing video V1 based on the performance sound of the karaoke performance of the song X1, the singing voice of the singer, and the video image obtained by shooting the singer, and streams it to the server device S. Send.

At this time, the transfer unit 300 stores the time when the karaoke performance of the song X1 was started (performance start time). As shown in FIG. 8, in this example, the performance start time of song X1 is 12:15:00.

The distribution unit 82b performs live distribution of the streaming-transmitted singing video V1 to the viewer terminal. The viewer views the singing video V1 via the viewer terminal.

In addition, the viewer browses the open voting music list L1 via the viewer terminal. The viewer selects, via the viewer terminal, a song that the singer wants to sing in karaoke from among the songs X2 to X5 included in the voting song list L1. The voting unit 75c of each viewer terminal transmits to the server device S voting information indicating the selected music piece. The storage means 80 of the server device S stores the received voting information.

Triggered by the fact that the remaining performance time (04:55) of the song X1 being played in karaoke reaches a predetermined time, the karaoke machine K instructs the tallying unit 82c to tally the voting information. In this example, it is assumed that the predetermined time is "5 seconds". That is, the karaoke machine K instructs the start of tallying the vote information when the time reaches 12:19:50. The tallying unit 82c tallies the voting information transmitted from each viewer terminal so far and calculates the voting result.

Here, it is assumed that the voting results for music X2: 3000 votes, music X3: 2500 votes, music X4: 5000 votes, and music X5: 1000 votes.

The tallying unit 82c transmits to the karaoke device K the music ID of the music X4 with the highest number of votes among the music included in the voting music list L1. The determination unit 400 determines the song X4 as the song to be performed in karaoke next from among the songs included in the voting song list L1.

The tallying unit 82c erases the voting information stored in the storage unit 80 at the time of tallying, and temporarily suspends acceptance of the voting information. Also, the performance processing unit 200 of the karaoke machine K ends the karaoke performance of the song X1 (the performance end time is 12:19:55; see FIG. 8). The transfer unit 300 terminates the streaming transmission of the singing video V1 to the server device S. The distribution unit 82b of the server device S ends the live distribution of the singing video V1. The viewer finishes viewing the singing video V1.

Here, the performance processing unit 200 adds the average time of the talks performed so far and the performance time of the song X4 determined as the next song (second song) to the current time, and the difference from the delivery end time remains. By confirming whether or not the playing time is longer than each of the three pieces of music, it is determined whether or not the next piece of music X4 is the last piece of music. At this time, a spare time for talking after the performance of the music piece X4 is finished may be added.

As shown in FIG. 8, the time of the talk T1 performed so far is 01:00, the performance time of the song X4 is 05:55, and the current time (that is, the end time of the karaoke performance of the song X1) is 12:00. :19:55. Therefore, the estimated performance end time of the song X4 including the spare time of the talk T2 performed before karaoke singing of the song X4 is 12:26:10, and the difference from the distribution end time (12:34:00) is 07. : 50. Here, among the performance times of the remaining three songs, the longest performance time is 05:30 of song X2. Therefore, since karaoke performance is possible for any song, the performance processing unit 200 does not set the song X4 as the last song.

As described above, the determining unit 400 determines the song X4 as the song to be performed in karaoke next from among the songs included in the voting song list L1. The voting music list generation unit 100 updates the set list by deleting from the set list L0 the music X1 for which the karaoke performance was performed and the music X4 which was determined to be the next music to be karaoke performed, and sends the voting music list L2 to the server. Send to device S. The voting music list L2 includes music X2, music X3, and music X5.

Here, it is assumed that the singer starts talking T2 after karaoke singing of the music piece X1. In this case, the transfer unit 300 of the karaoke machine K generates the talk video W2 based on the voice of the talk T2 and the video image obtained by photographing the singer, and transmits it to the server device S by streaming.

The distribution unit 82b performs live distribution of the streaming-transmitted talk video W2 to the viewer terminal. The viewer views the talk video W2 via the viewer terminal.

After finishing the talk T2, the singer uses the remote control device 50 to perform an operation input to start karaoke performance. In accordance with the operation input for starting the karaoke performance, the transfer unit 300 ends the streaming transmission of the talk video W2 to the server device S. The distribution unit 82b of the server device S ends the live distribution of the talk video W2. The viewer finishes viewing the talk video W2.

On the other hand, based on the operation input for starting the karaoke performance, the performance processing section 200 of the karaoke device K starts the karaoke performance based on the performance data of the song X4. The singer sings karaoke along with the karaoke performance. The transfer unit 300 of the karaoke device K generates a singing video V2 based on the performance sound of the karaoke performance of the song X4, the singing voice of the singer, and the video image obtained by shooting the singer, and streams it to the server device S. Send.

At this time, the transfer unit 300 stores the time when the karaoke performance of the song X4 was started (performance start time). As shown in FIG. 8, in this example, the performance start time of song X4 is 12:22:00.

The distribution unit 82b performs live distribution of the streaming-transmitted singing video V2 to the viewer terminal. The viewer views the singing video V2 via the viewer terminal. In addition, the publishing unit 82a of the server device S publishes the voting music list L2 and starts accepting voting information.

The viewer browses the open voting music list L2 via the viewer terminal. The viewer selects, via the viewer terminal, a song that the singer wants to sing in karaoke from among the songs X2, X3, and X5 included in the voting song list L2. The voting unit 75c of each viewer terminal transmits to the server device S voting information indicating the selected music piece. The storage means 80 of the server device S stores the received voting information.

The karaoke machine K instructs the tallying unit 82c to tally the voting information when the remaining performance time (05:55) of the song X4 being played karaoke reaches a predetermined time. That is, the karaoke machine K instructs to start tallying the vote information when 12:27:50 is reached. The tallying unit 82c tallies the voting information transmitted from each viewer terminal so far and calculates the voting result.

Here, it is assumed that the voting results for song X2 are 2000 votes, song X3 is 3000 votes, and song X5 is 2500 votes.

The tallying unit 82c transmits to the karaoke device K the song ID of the song X3 with the highest number of votes among the songs included in the voting song list L2. The determination unit 400 determines the song X3 as the song to be performed in karaoke next from among the songs included in the voting song list L2.

The tallying unit 82c erases the voting information stored in the storage unit 80 at the time of tallying, and temporarily suspends acceptance of the voting information. Also, the performance processing unit 200 of the karaoke apparatus K ends the karaoke performance of the song X4 (the performance end time is 12:27:55; see FIG. 8). The transfer unit 300 terminates the streaming transmission of the singing video V2 to the server device S. The distribution unit 82b of the server device S ends the live distribution of the singing video V2. The viewer finishes viewing the singing video V2.

Here, the performance processing unit 200 adds the average time of the talk performed so far and the performance time of the music X3 determined as the next music (the third music) to the current time, and the difference from the delivery end time remains. It is determined whether or not the next music X3 is the last music by confirming whether or not it is longer than the performance time of each of the two music pieces.

As shown in FIG. 8, the average time of talk T1 and talk T2 performed so far is 01:33, the performance time of song X3 is 03:55, and the current time (that is, the end of karaoke performance of song X4). time) is 12:27:55. Therefore, the estimated performance end time of the song X3 including the spare time of the talk T3 performed before karaoke singing of the song X3 is 12:33:13, and the difference from the distribution end time (12:34:00) is 00. : 47. Here, since the performance time of the remaining two songs is longer than 00:47, no further karaoke performance is possible. Therefore, the performance processing section 200 sets the music piece X3 as the last piece of music. When the last song is decided, the processing related to the update of the set list, disclosure of the voting song list, tallying of voting information, etc., ends.

Suppose that the singer started talking T3 after singing karaoke of the music piece X4.
