The audio controller 102b receives a voice signal from each of the user terminals 104-1, 104-2, and 104-3, and synthesizes the voice signals to each of the user terminals 104-1, 104-2, 104-3. can be sent to In this case, the audio controller 102b may synthesize voice signals of users other than the corresponding user and transmit the synthesized voice signals to the corresponding user terminal 104 .

For example, the audio controller 102b synthesizes and transmits the voice signals of the second user terminal 104-2 and the third user terminal 104-3 to the first user terminal 104-1, and transmits the second To the user terminal 104-2, the voice signals of the first user terminal 104-1 and the third user terminal 104-3 are synthesized and transmitted, and to the third user terminal 104-3, the first user terminal is transmitted. The voice signals of (104-1) and the second user terminal 104-2 may be synthesized and transmitted.

The plurality of user terminals 104 may be terminals of users using an online karaoke service. Each user may be located at a remote location (a different region or location). Here, it is illustrated that there are three user terminals 104-1, 104-2, and 104-3 for convenience, but the number of user terminals 104 is not limited thereto.

An application for providing an online karaoke service may be installed in the user terminal 104 . The application may be stored in a computer-readable storage medium of the user terminal 104 . The application includes a predetermined set of instructions executable by the processor of the user terminal 104 .

The computer-readable storage medium of the user terminal 104 includes components of an operating system for executing a set of instructions, such as the application, on the user terminal 104 . For example, such an operating system may be Apple's iOS or Google's Android.

A plurality of user terminals 104 may be respectively connected to the karaoke management server (102). One of the plurality of user terminals 104 may be a host user terminal, and the rest may be a guest user terminal. Here, for convenience, it will be described that the first user terminal 104-1 is a host user terminal, and the second user terminal 104-2 and the third user terminal 104-3 are guest user terminals.

2 is a diagram illustrating an online karaoke service method according to an embodiment of the present invention. In the illustrated flowchart, the method is described by dividing the method into a plurality of steps, but at least some of the steps are performed in a reversed order, are performed together in combination with other steps, are omitted, are performed separately, or are not shown. One or more steps may be added and performed.

Referring to FIG. 2 , the first user terminal 104 - 1 may access the karaoke management server 102 and transmit a karaoke opening request to the karaoke management server 102 ( S 101 ).

Here, when the karaoke management server 102 opens an online karaoke according to a karaoke establishment request, the second user terminal 104-2 and the third user terminal 104-3 may participate in the online karaoke. When an online karaoke room is opened, each user terminal 104-1, 104-2, 104-3 sends and receives a voice signal at a preset unit period (eg, 4ms, etc.) through the karaoke management server 102 . can For example, each user may exchange a voice signal with each other before selecting a song.

Each of the user terminals 104-1, 104-2, and 104-3 may transmit the corresponding user's voice signal as an uncompressed audio signal. That is, each user terminal 104-1, 104-2, 104-3 may transmit the corresponding user's voice signal as PCM data in the form of uncompressed lossless data without a separate encoding process.

In this case, since each user terminal 104-1, 104-2, 104-3 does not need to decode another user's voice signal, it is possible to minimize the time required to process the voice signal in the user terminal. . That is, by excluding the process of encoding and decoding the voice signal in the user terminal, it is possible to minimize the delay time for receiving and transmitting the voice signal in the user terminal.

Here, the online karaoke service may be executed in a network environment capable of processing high-speed and high-capacity data, such as a 5G network. In this case, it is possible to transmit a voice signal between user terminals in real time, and it is possible to reduce the overall delay time to a level that the user hardly notices (eg, 50 to 60 ms).

Next, the first user terminal 104-1 may transmit music selection information to the karaoke management server 102 (S103). In an exemplary embodiment, the karaoke management server 102 may transmit music selection information to the second user terminal 104-2 and the third user terminal 104-3.

Here, it has been described that the karaoke management server 102 informs other guest users of music selection information when the host user selects music, but the present invention is not limited thereto. The information may also be transmitted to the karaoke management server 102 .

Next, each of the user terminals 104-1, 104-2, 104-3 may download an accompaniment (Music Recorded: MR) corresponding to the music selection information from the karaoke management server 102 (S 105).

Next, when the download of the accompaniment corresponding to the music selection information is completed, each user terminal 104-1, 104-2, 104-3 may transmit an accompaniment download completion signal to the karaoke management server 102 (S). 107).

Next, the karaoke management server 102, when the accompaniment download complete signal is received from all the user terminals (104-1, 104-2, 104-3), to the first user terminal (104-1), which is the user terminal of the room. An accompaniment preparation completion signal may be transmitted (S109).

Next, the first user terminal 104-1 may insert the accompaniment start signal into the voice signal of the room owner and transmit it to the karaoke management server 102 (S 111).

Specifically, the first user terminal 104-1 transmits the user's voice signal in a preset unit period (eg, 4ms) to the second user terminal 104-2 and the second user terminal 104-2 through the karaoke management server 102. 3 It is in a state of being transmitted to the user terminal 104-3. Here, when receiving the accompaniment preparation completion signal from the karaoke management server 102, the first user terminal 104-1 inserts the accompaniment start signal into the voice signal of the room owner of the next unit period, and then the karaoke management server 102 ) can be sent.

Here, when a voice signal is transmitted with a period of 4 ms, 192 numbers are included in the PCM type voice signal as shown in FIG. 3 . Here, the 192 numbers may consist of numbers within the range of -32768 to +32768. The first user terminal 104 - 1 may insert a number sequence having a preset rule in the number of preset numbers in the front part of the voice signal of the host user as an accompaniment start signal.

For example, the first user terminal 104-1 may insert the same number, such as 999, 999, 999, as an accompaniment start signal to three numbers in the front part of the voice signal of the host user (( in FIG. a)). Alternatively, the first user terminal 104-1 inserts a continuous number sequence such as 999, 998, 997 (or 886, 887, 888) into three numbers in the front part of the voice signal of the chairperson as an accompaniment start signal. It can be done (FIG. 7(b)). The first user terminal 104 - 1 may transmit the voice signal of the host user including the accompaniment start signal and reproduce the accompaniment corresponding to the music selection information.

Next, the karaoke management server 102 may transmit the user's voice signal including the accompaniment start signal to the second user terminal 104-2 and the third user terminal 104-3 (S113). .

Next, when the second user terminal 104-2 and the third user terminal 104-3 detect the accompaniment start signal from the voice signal of the host user, the accompaniment corresponding to the music selection information may be reproduced (S). 115).

Next, the first user terminal 104 - 1 may insert the accompaniment adjustment signal in the voice signal of the user of the room and transmit it to the karaoke management server 102 ( S117 ). That is, since the second user terminal 104-2 and the third user terminal 104-3 may not receive the user's voice signal including the accompaniment start signal due to the network environment, etc., the first The user terminal 104 - 1 may transmit the accompaniment adjustment signal to the karaoke management server 102 by inserting the accompaniment adjustment signal into the voice signal of the host user after transmitting the voice signal of the host user including the accompaniment start signal.

Specifically, the first user terminal 104 - 1 may check the time length of a silent section (ie, a section in which no sound is produced) in the accompaniment corresponding to the music selection information. In general, in accompaniment, there is a silent section of a certain length of time (eg, 30ms, etc.) at the beginning of the accompaniment. The first user terminal 104 - 1 may insert an accompaniment adjustment signal into the voice signal of the room owner during the silent section and transmit it to the karaoke management server 102 .

The first user terminal 104 - 1 may determine the transmission frequency and transmission period of the host user's voice signal including the accompaniment adjustment signal according to the length of the silent section. The first user terminal 104 - 1 may set the transmission period of the user's voice signal including the accompaniment adjustment signal as a period corresponding to a multiple of the unit period. For example, when the unit period of the voice signal is 4 ms, the transmission period of the host user's voice signal including the accompaniment adjustment signal may be 8 ms, twice the unit period, or 12 ms, three times the unit period.

In an exemplary embodiment, when the time length of the silent section in the accompaniment corresponding to the music selection information is 30 ms, the first user terminal 104-1 transmits the voice signal of the host user including the accompaniment adjustment signal with a transmission period of 3 ms. It can be transmitted twice (ie, transmitted at 8 ms, 16 ms, and 24 ms after the start of accompaniment playback, respectively). The first user terminal 104-1 may insert a number sequence having a preset rule in the number of preset numbers in the front part of the voice signal of the host user as an accompaniment adjustment signal.

Here, the accompaniment adjustment signal included in the user's voice signal transmitted once (8 ms), twice (16 ms), and three times (24 ms) may be provided differently. For example, 777, 777, and 777 are inserted as accompaniment adjustment signals in the three numbers in the front part of the voice signal of the host user sent the first time, and 3 in the front part of the voice signal of the chairman user sent the second time 555, 554, and 553 are inserted as accompaniment adjustment signals in the number of digits, and 442, 443, and 444 can be inserted as accompaniment adjustment signals in the three numbers in the front part of the user's voice signal transmitted at the 3rd time.

The accompaniment adjustment signal included in the voice signal of the host user transmitted once (8ms) may mean to move the accompaniment playback time to 8ms. The accompaniment adjustment signal included in the voice signal of the host user transmitted twice (16ms) may mean to move the accompaniment playback time to 16ms. The accompaniment adjustment signal included in the voice signal of the host user transmitted three times (24ms) may mean to move the accompaniment playback time to 24ms.

Meanwhile, although it has been described herein that the voice signal of the host user including the accompaniment adjustment signal is transmitted at a preset transmission period, the present invention is not limited thereto and may be transmitted without a specific period. For example, the first user terminal 104-1 transmits the accompaniment adjustment signal once at 8 ms after the start of accompaniment reproduction, transmits the accompaniment adjustment signal twice at 12 ms, and 3 times at 20 ms An accompaniment adjustment signal may be transmitted.

As such, by inserting and transmitting the accompaniment adjustment signal in the silent section of the accompaniment, each user cannot audibly recognize that the playback timing of the accompaniment has moved. It becomes possible to synchronize the accompaniment playback time between the two.

Next, the karaoke management server 102 may transmit the user's voice signal including the accompaniment adjustment signal to the second user terminal 104-2 and the third user terminal 104-3 (S 119) .

Next, when the second user terminal 104-2 and the third user terminal 104-3 detect the accompaniment adjustment signal from the voice signal of the host user, the accompaniment reproduction time point is moved to a time point corresponding to the accompaniment adjustment signal. It can be done (S 121).

For example, when the current accompaniment is played back in the second user terminal 104-2 is 4 ms, when 777, 777, 777 are detected as the accompaniment adjustment signal in the voice signal of the host user, the second user terminal ( 104-2) can move the accompaniment playback time from the current 4ms to 8ms. In addition, when the current accompaniment is played back at 18 ms in the third user terminal 104-3, when 555, 554, and 553 are detected as the accompaniment adjustment signal from the voice signal of the host user, the second user terminal 104- 2) can move the accompaniment playback time from the current 18ms to 16ms.

Meanwhile, when the accompaniment reproduction is completed, each user terminal 104-1, 104-2, and 104-3 may calculate a song score of the corresponding user and transmit the calculated song score to the karaoke management server 102. Then, the karaoke management server 102 sums up the song scores received from each user terminal (104-1, 104-2, 104-3) to each user terminal (104-1, 104-2, 104-3) can send

According to the disclosed embodiment, when receiving the accompaniment preparation completion signal from the karaoke management server 102, the first user terminal 104-1 inserts the accompaniment start signal into the user's voice signal and transmits it, thereby providing online karaoke. You will be able to match the start time of accompaniment playback with other participating users. In addition, after the accompaniment start signal is transmitted from the first user terminal 104-1, the accompaniment adjustment signal is inserted into the user's voice signal and transmitted, so that even after the accompaniment reproduction starts, the accompaniment reproduction timings can be matched.
