Referring to fig. 1, an embodiment of the present invention provides a multimedia scoring system 1, which includes a database 10, a karaoke main system 12, a mixing module 14, and an auxiliary scoring system 16.
The database 10 stores a plurality of song data 100 and a corresponding plurality of song score timing data 102. In an embodiment of the present invention, a plurality of song data 100 to be used by the K song host system 12 may be stored in the database 10, and the song data 100 may include, for example, song data sung by a particular singer, unmanned accompaniment data, lyric data, and videocassette data. On the other hand, the song scoring timing data 102 may include original audio data corresponding to the plurality of song data 100 and subsequently used for scoring the singing content of the user, and is edited to have time tags corresponding to each sentence of lyrics, and original audio data, pitch, tempo, length, volume data, music score data, and the like corresponding to the time tags.
The karaoke host system 12 of the present invention is further illustrated. The apparatus implementing the karaoke host system 12 may include hardware, firmware, and/or software and may take any of a variety of forms. Typical examples of such means include notebook computers, smart phones, small personal computers, personal digital assistants, smart televisions, cloud top boxes, and the like. The functionality described herein may also be implemented in a peripheral device or in an embedded card. By way of further example, such functionality may also be implemented on different chips or on a circuit board executing different programs on a single device. For example, the karaoke host system 12 may be used to execute karaoke software or play karaoke tracks in the above-described apparatus.
As shown in fig. 1, the karaoke host system 12 is electrically connected to the database 10 and includes a user interface 120, a first communication module 122 and a first processing unit 124. The karaoke host system 12 may include at least one controllable display device for displaying the user interface 120, and may be, for example, an interface for the user to control, such as a touch interface, and the user may input various instructions through the user interface 120, such as a karaoke software execution command, a play command, a stop command, a song designation command, and the like. The user interface 120 may further provide a window corresponding to the song data 100 for the user to select a specific song desired to sing.
The first communication module 122 may be used to electrically connect the karaoke host system 12 to the database 10. Alternatively, the database 10 may be built in a device for executing the karaoke host system 12, directly electrically connected to the karaoke host system 12, or communicatively connected through a wired network or a wireless network, but is not limited to the above. The first communication module 122 may be, for example, a USB communication module, an ethernet communication module, a wireless network communication module, or a wireless bluetooth communication module. Another use of the first communication module 122 is to transmit a synchronization request signal S1 to obtain a synchronization timing signal S2 indicating synchronization timing, which S2 is used for time synchronization of song playing and scoring, and will be described later.
In other words, the first processing unit 124 may be configured to obtain the designated song data 20 and the designated song scoring timing data 22 from the database 10 according to the song designation command received from the user interface 120, and control the user interface 120 to play the designated song data 20 according to the song designation command. In detail, the designated song data 20 and the designated song score timing data 22 are designated by the user, and one of the song data 100 selected from the plurality of song data 100 and the corresponding song score timing data 102 is selected.
On the other hand, the functions of the first processing unit 124 may be implemented by using one or more processing units. The first processing unit 124 may be a programmable unit, such as a microprocessor, a microcontroller, a Digital Signal Processor (DSP) chip, a Field-programmable gate array (FPGA), and the like. The functions of the first processing unit 124 may also be implemented by one or several electronic devices or ICs. In other words, the functions performed by the first processing unit 124 may be implemented within a hardware domain or a software domain or a combination of a hardware domain and a software domain.
Further, the mixing module 14 of the present invention is explained. The sound mixing module 14 is electrically connected to the sound receiving unit 18, and can be configured to receive sound through the sound receiving unit 18 and generate human voice data 24. The mixing module 14 can integrate sounds from multiple sources into a Stereo (Stereo) or Mono (Mono) soundtrack, and can adjust the frequency, dynamics, pitch, localization, reverberation, and sound field of each respective original signal individually as needed to optimize each soundtrack, which is then superimposed with the human voice data 24. The Mixing module 14 may include a Synthesizer (Synthesizer), a Signal Processor (Signal Processor) and a Mixing Console (Mixing Console), or may use software Mixing to achieve the above-mentioned effects.
In addition, the sound receiving unit 18 may be, for example, a microphone, and may be electrically connected to the sound mixing module 14 in a wired or wireless manner. The mixing module 14 may be electrically connected to the karaoke host system 12 and the auxiliary scoring system 16 in a wired or wireless manner.
In a specific embodiment, the mixing module 14 may simply transmit the unmixed human voice data 24 to the karaoke host system 12, and play the mixed voice data through an audio playing unit (e.g., a speaker) of the karaoke host system 12 after the human voice data 24 is mixed by the karaoke host system 12 to generate the mixed voice data.
In an alternative embodiment, the remix module 14 may optimally remix the human voice data 24 and the designated song data 20 to generate remix data, and transmit the remix data to the karaoke host system 12 to play the remix data through an audio playing unit (e.g., a speaker) of the karaoke host system 12. Therefore, the singer can listen to his or her own singing voice after being played through the audio playing unit. Meanwhile, in the above embodiment, the mixing module 14 also transmits the unmixed voice data 24 to the auxiliary scoring system 16 for analysis, comparison and scoring during the subsequent singing scoring.
Before describing the details of song scoring, the auxiliary scoring system 16 of the present invention will first be described. In order to solve the problem that the existing karaoke host system has no professional intelligent scoring function, the multimedia scoring system 1 of the present invention further provides an auxiliary scoring system 16 electrically connected to the karaoke host system 12 and the mixing module 14, and including a second communication module 160, a first timing unit 162, a sampling unit 164 and a second processing unit 166. The means for implementing secondary scoring system 16 may comprise hardware, firmware, and/or software, and may take any of a variety of forms. Typical examples of such means include a laptop, a smart phone, a small personal computer, a personal digital assistant or a plug and play USB device, etc. The functionality described herein may also be implemented in a peripheral device or in an embedded card. By way of further example, such functionality may also be implemented on different chips or on a circuit board executing different programs on a single device. In this embodiment, although the first timing unit 162 is included in the auxiliary scoring system 16 and is used for providing the synchronous timing signal S2, the invention is not limited thereto, and another timing unit may be disposed in the karaoke main system 12, and will be described in the following embodiments.
The second communication module 160 is used for connecting with the first communication module 122 through a first communication protocol, for example, a USB communication protocol, and the second communication module 160 can be used for obtaining the synchronization timing signal S2 from the first timing unit 162. Similarly, the second communication module 160 may be, for example, a USB communication module, an ethernet communication module, a wireless network communication module, or a wireless bluetooth communication module.
Generally speaking, when a song is scored in real time between the main karaoke system 12 and the auxiliary scoring system 16, the difficulty lies in the difference of the time sequence between the two systems, and it is difficult to achieve the goal of real-time feedback of the scoring of the song. Therefore, in order to synchronize the signal streams of the two, in the embodiment of the present invention, when the first processing unit 124 controls the user interface 120 to play the designated song data 20 according to the song designation command, the first communication module 122 is first controlled to issue the synchronization request signal S1 to the second communication module 160, and in response thereto, the second communication module 160 transmits the acquired synchronization timing signal S2 to the first communication module 122. After obtaining the synchronization timing, the first processing unit 124 calculates a synchronization start point according to the synchronization timing and the designated song score timing data 22 to correspondingly generate a start point indication signal S3 indicating the synchronization start point, and transmits the start point indication signal S3 and the designated song score timing signal S4 with the designated song score timing data 22 to the auxiliary scoring system 16 through the first communication module 122. For example, the first processing unit 124 may obtain the time point of the start of the lyric of the first sentence in the designated song scoring timing data 22 as the synchronization start point to generate a corresponding start point indication signal S3.
Then, the second communication module 160 further receives the start point indication signal S3 and the designated song scoring timing signal S4. The sampling unit 164 may receive the human voice data 24 from the mixing module 14 and sample the human voice data 24. Sampling may include converting the human voice data 24, which is originally an analog signal, into a digital signal that may be recognized or processed by the second processing unit 166 for use in scoring subsequent songs.
Similarly, the functions of the second processing unit 166 may be implemented using one or more processing units. The second processing unit 166 may be a programmable unit such as a microprocessor, a microcontroller, a Digital Signal Processor (DSP) chip, a Field-programmable gate array (FPGA), and the like. The functions of the second processing unit 166 may also be implemented by one or several electronic devices or ICs. In other words, the functions performed by the second processing unit 166 may be implemented within a hardware domain or a software domain or a combination of a hardware domain and a software domain.
Further, the designated song score timing signal S4 may have a specific signal format, and therefore, the designated song score timing signal S4 is decoded by the second processing unit 166 to obtain the designated song score timing data 22, which includes a time stamp corresponding to each lyric of the designated song data 20, and original audio data, pitch, tempo, length, volume data, and melody data corresponding to the time stamp, and the song scoring procedure is executed when the synchronization start point is reached according to the synchronization start point indicated by the start point indication signal S3.
The song scoring procedure will be described together with the embodiment of the multimedia scoring method provided by the invention. Please refer to fig. 2, which is a flowchart illustrating a multimedia scoring method according to an embodiment of the invention. It should be noted that the multimedia scoring method of the present embodiment can be applied to the multimedia scoring system of the above embodiments, but is not limited thereto.
As shown in fig. 2, for convenience of description, the flow is divided according to the configuration of the karaoke main system and the auxiliary scoring system, and repeated descriptions in some steps will be omitted. The multimedia scoring method of the embodiment of the invention comprises the following steps:
step S100: the configuration user interface 120 receives a song designation command input by the user.
Step S101: the first processing unit 124 is configured to obtain the designated song data 20 and the designated song scoring timing data 22 from the database 10 according to the song designation command.
Step S102: the first timing unit 162 is configured to generate a synchronization timing signal S2 for indicating synchronization timing.
Step S103: the first communication module 122 is configured to connect with the second communication module 160 via a first communication protocol for obtaining the synchronization timing signal S2.
Step S104: the first processing unit 124 is configured to control the user interface 120 to play the specified song data 20.
Step S105: the first processing unit 124 is configured to calculate a synchronization start point according to the synchronization timing and the designated song score timing data 22, so as to generate a start point indication signal S3 for indicating the synchronization start point.
Step S106: the start point indication signal S3 and the designated song scoring timing signal S4 are transmitted to the auxiliary scoring system 16 through the first communication module 122.
Step S107: the second processing unit 166 is configured to decode the designated song score timing signal S4. Here, the designated song score timing signal S4 has the designated song score timing data 22 encoded so that decoding thereof results in the designated song score timing data 22.
Step S108: the second processing unit 166 is configured to execute a song scoring procedure when the synchronization start point is reached according to the synchronization start point indicated by the start point indication signal S3. For example, the second processing unit 166 may obtain the designated song score timing data 22 from the Karaoke host system 12, with the point in time when the first lyric begins as the synchronization starting point, and the singer typically begins singing at the point in time when the first lyric begins. The song scoring program begins to score the voice data after the synchronous starting point, and comprises the following steps:
step S109: the control sampling unit 164 continuously samples a portion of the human sound data 24 after the start point to generate sampled audio data.
Step S110: the sampled audio data is compared to the specified song score timing data 22 to obtain a comparison result. In this step, the sampled audio data is data obtained by sampling the singing voice of the singer, and the comparison result can be obtained by comparing the time tag of each lyric with the original singing audio data, pitch, tempo, length, volume data, melody data and the like corresponding to the time tags in the designated song scoring time sequence data 22.
Step S111: and according to the comparison result, scoring is carried out and scoring result data S5 is correspondingly generated. In this step, in order to generate scoring result data in real time, data collection and analysis are usually performed in units of one lyric, the second processing unit 166 may determine whether the currently obtained sampled audio data is sufficient, for example, whether the sampled audio data of a complete lyric has been obtained according to the time tag of each lyric, and then determine to output the comparison result.

Please further refer to fig. 6A and 6B, which are flowcharts of a multimedia scoring method according to another embodiment of the present invention. According to the multimedia scoring system provided in fig. 4 and 5, the multimedia scoring method of the present invention may further include the following steps:
step S200: the first communication module 122 and the second communication module 160 are configured to connect with the first timing unit 162 through the network 34, and obtain the synchronous timing signal S2 generated by the first timing unit 162 through the network 34, wherein the synchronous timing signal S2 may be, for example, the network clock timing signal 26.
Step S201: the karaoke host system 12 and the secondary scoring system 16 are synchronized to the first timing unit 162.
Step S202: after the first processing unit 124 is configured to calculate the synchronization start point according to the synchronization timing provided by the first timing unit 162, it transmits a start point indication signal S3 to the auxiliary scoring system 16.
In another aspect, the multimedia scoring method of the present invention may further include the steps of:
step S203: the first processing unit 124 is configured to first transmit the designated song data 20 and the designated song scoring timing data 22 to the remix module 14 through the third communication module 142.
Step S204: the remix module 14 is configured to remix the human voice data 24 in accordance with the specified song data 20 to generate remix data.

Referring to fig. 7, a system block diagram of a multimedia scoring system according to another embodiment of the invention is shown. As shown, the karaoke host system 12 further includes a second timing unit 128 configured to generate another timing synchronization signal. For example, the first communication module 122 and the second communication module 160 may allocate the main system 12 and the auxiliary scoring system 16 of the K song as a Master synchronization device (e.g., PTP Master) and a Slave synchronization device (PTP Slave) according to a first communication Protocol, such as IEEE-1588 Precision Time Protocol (PTP), for example, IEEE-1588v2 PTP, so as to determine that the timing synchronization signal S2 generated by the first timing unit 126 or another timing synchronization signal generated by the second timing unit 128 is synchronized between the main system 12 and the auxiliary scoring system 16 of the K song. For example, when the karaoke master system 12 is used as the master synchronization device and the auxiliary scoring system 16 is used as the slave synchronization device, the timing synchronization signal of the second timing unit 128 is used as the reference for synchronization to calculate the synchronization start point, and vice versa.
On the other hand, in the present embodiment, the karaoke host system 12 and the auxiliary scoring system 16 are in different network environments. For example, the karaoke host system 12 is connected to the network 34 through a first communication module 122, such as an ethernet module, the auxiliary scoring system 16 is connected to the network 34 through a second communication module 160, such as a 3G/4G/5G network communication module, and the mixing module 14 may further include a sixth communication module 146, such as a wireless network module, connected to the karaoke host system 12 through a first network interface (e.g., a WIFI network interface). At this time, the karaoke host system 12 and the mixing module 14 are in an internal network, and the auxiliary scoring system 16 is in an external network. The auxiliary scoring system 16 is further connected to the fourth communication module 144 of the mixing module 14 by the fifth communication module 168 through the second network interface 38. The fourth communication module 144 and the fifth communication module 168 can be bluetooth communication modules, and the second network interface 38 can be a bluetooth transmission interface.
In this embodiment, in order to solve the timing synchronization problem of the internal and external networks, the synchronization between the main K song system 12 and the auxiliary scoring system 16 may still be achieved by using the aforementioned first communication Protocol, for example, IEEE-1588 Precision Time Protocol (PTP). To this end, the first communication module 122 and the second communication module 160 are also configured to pass through the fourth communication module 144, the fifth communication module 168 and the sixth communication module 146 to allocate the karaoke host system 12 and the secondary scoring system 16 as a primary synchronization device (e.g., PTP Master) and a secondary synchronization device (PTP Slave).
In other words, after determining the Master synchronization device (e.g., PTP Master) and the Slave synchronization device (PTP Slave) through the signal paths, the K host system 12 may obtain the corresponding synchronization timing signal S2 to calculate the synchronization start point and generate the start point indication signal S3. It is contemplated that the start point indicating signal S3, the designated song scoring timing signal S4 and the scoring result data S5 may be transmitted directly through the network 34 or through the signal paths of the fourth communication module 144, the fifth communication module 168 and the sixth communication module 146. The karaoke host system 12 and the auxiliary scoring system 16 can select the path transmission start point indication signal S3, the designated song scoring timing signal S4 and the scoring result data S5 with faster transmission according to the current network transmission status.
