First embodiment

Referring to FIG. 1 , it is a schematic structural diagram of a singing visual special effects system according to a first embodiment of the present invention. As shown in FIG. 1, the vocal visual effects system 100 includes a hand-held tilt sensing component 15, a control host 10, and a visual effects output device 11.

The hand-held tilt sensing component 15 can be an electronic device having a sensor disposed therein for sensing the tilt angle of the hand-held tilt sensing component 15. The sensor can be any sensor that can realize tilt angle sensing, such as an accelerometer, a gyroscope, and the like.

The hand-held tilt sensing component 15 can be a dedicated electronic device, that is, an electronic device whose primary purpose is to transmit tilt data to the control host 10 without implementing other functions. Due to its singular function, the hand-held tilt sensing element 15 can be made small at this time, so that it can be attached to other devices that are often required for handheld use, such as the microphone 101.

The hand-held tilt sensing element 15 can also be integrated with other electronic devices such as microphones, electronic fluorescent bars, and the like. When a microphone is integrated with the hand-held tilt sensing element, its appearance is no different from that of a general microphone. The difference is that in addition to transmitting the singing voice of the singer 112, the hand-held tilt sensing component synchronizes the tilt data to the control host. 10.

The handheld tilt sensing component 15 can also be other general purpose smart electronic devices such as smart phones, smart bracelets or other wearable electronic settings. This type of hand-held tilt sensing component 15 generally includes various types of sensors that allow the hand-held tilt sensing component 15 to achieve the above-described simultaneous tilting of the control host 10 by running a particular application within the hand-held tilt sensing component 15. The function of the data, that is, the smart electronic device also serves as a hand-held tilt sensing element.

The handheld tilt sensing component 15 and the control host can be connected by wireless or wired. After sensing the tilt data, the hand held tilt sensing component 15 can synchronize it to the control host 10. The above-mentioned inclination data may be instantaneously sampled and sent to the control host 10 in synchronization, and may also be synchronized to the control host 10 for multiple sampling and average after each sampling period. It can be understood that even if the sampling average is over a sampling period, when the sampling period is small, the transmission of the inclination data can be considered to be instantaneous. In addition, the tilt data can be the original data, that is, the original data output by the sensor. As such, the control host 10 needs to perform calculations to obtain the inclination after receiving the inclination data. The slope data can also be a calculation result or an intermediate data. When the inclination data is the calculation result, the control host 10 can directly use the calculation result as the inclination.

Specific implementations of the control host 10 include, but are not limited to, a personal computer, a multimedia player, a single chip microcomputer, a data player, a smart phone, and a dedicated control chip.

The visual effect output device 11 can be any display device capable of outputting video signals, such as a single display screen, a display screen array composed of multiple display screens, a single luminaire (such as an LED lamp), a luminaire array composed of a plurality of luminaires, and a single projection. An instrument, a projector array of multiple projectors, and the like.

In a specific embodiment, the visual effect output device 11 includes an array of LED lights, each of which can output different lights according to different signals input, and the lights of all the LED lights together constitute a whole vision. Special effects. It can be understood that the form of visual effects is not subject to any restrictions. The LED array described above can cover all the walls, roofs and floors of the room, so that the visual effects of the display can fully enclose the room and maximize the visual effects of the scene.

In a specific implementation manner, the visual effect output device 11 includes one or more display screens, each of which can display the same display signal, or can be separately controlled to display different display signals. The display of all the display screens together constitute the overall visual effect.

In a specific embodiment, the visual effect output device 11 includes one or more projectors, each of which can display the same display signal, or can be separately controlled to display different display signals. The display of all projectors together constitutes an overall visual effect.

Various types of visual effects output devices 11 can also be used in combination. For example, the visual effects output device 11 can include both an array of LED lights and one or more projectors or display screens.

The control host 10 and the visual effect output device 11 can be connected by wire or wirelessly. When connected by wire, for example, through a digital video interface (DVI interface), a high definition multimedia interface (HDMI interface), video graphics. The array interface (VGA interface) is connected, so that the video signal can be directly transmitted. If the control host 10 and the visual effect output device 11 are connected wirelessly, the video special effect output device 11 needs to have a wireless module and a signal conversion module. The wireless module is used for transmitting and receiving wireless data, and the signal conversion module is used for The received wireless data is converted into a video signal of a predetermined format.

The control host 10 acquires a visual special effects data set corresponding to the multimedia file when playing the multimedia file or when the external device plays the multimedia file. It can be understood that if the visual effect data set is acquired when the external device plays the multimedia file, the external device needs to send a signal to the control host 10 for playing the multimedia file, and the identifier of the multimedia file to be played is included in the signal.

The above-mentioned external device and control host 10 can be connected to each other through a wired network or a wireless network, and a specific application running in the host 10 can be monitored to monitor a specific network. The external device can send the identifier of the played multimedia file and the time when the multimedia file starts to be played to the specific network. In this way, the control host 10 can receive the identifier of the multimedia file sent by the external device and the time when the multimedia file starts to be played. In addition, the control host 10 and the external device can also be connected to the same server system, and when the external device plays the multimedia file, the identification information of the played multimedia file and the time of starting the playback can be submitted to the server system, and the server The system pushes the above information to the control host 10 or the control host 10 actively queries the server system to obtain the identifier of the multimedia file and the time when the multimedia file starts to be played.

Whether the control host 10 plays the multimedia file by itself or the external device plays the multimedia file, after the multimedia file starts playing, the control host 10 acquires the visual special effects data set corresponding to the multimedia file being played.

The visual effect data set described above may be stored in the control host 10 or stored in the cloud server system.

The visual effects data set may include a plurality of visual effects labels, each visual effect label including time setting data and special effect setting materials. The time setting data sets the effective time interval of the corresponding visual effect label, and the special effect setting data is used to set the manner of generating the visual special effect and other parameters.

It can be understood that the visual effect label here refers to the logical association between the time setting data and the special effect setting data, but does not mean that the specific data structure and storage structure of the visual special effect label, that is, the time setting data of the same visual special effect label. And the settings of the special effects are not limited to being saved.

The storage method of the special effect setting data set can be stored in the form of a file or stored in a database. The special effects setting data set is customized for each song by a manual or automated processing system.

If each visual effect label is used to represent a beat, then in a specific implementation, the visual effect data set can be as follows: [00:00.00] special effect setting data 1 [00:24.88] special effect setting data 2 [01: 27.05] Special effect setting data 3 [02:30.39] Special effect setting data 4 ... ...

Each time setting data, such as [00:24.88], is the starting time of the visual effect of one shot, and the visual effect ends naturally after the playing.

If a visual effect label contains multiple beat visual effects or contains static visual effects, then in a specific embodiment, the visual effects data set can be as follows: [00:00.00] special effect setting data 1 [00:24.88 ] Special effect setting data 2 [01:27.05] Special effect setting data 3 [02:30.39] Special effect setting data 4 ... ...

For the special effect setting data in this format, a time interval may be formed by two adjacent time starting points. For example, the time interval formed by [00:00.00]-[00:24.88] is the effective time of the special effect setting data 1. Interval.

It can be understood that the data format of the visual effect label is not limited thereto, and the time setting data may also include more information, for example, directly specifying the time interval, as follows: [00:00.00-00:23.86] effect setting data 1 [00: 24.88-01:00.90] Effect setting data 2 [01:27.05-03:29.00] Effect setting data 3 [03:30.39-05:38.86] Effect setting data 4

The first time in square brackets is the start time, and the latter time is the end time. In this way, a discontinuous time interval can be defined, and its adaptability is more flexible than just including the start time. In this case, no visual effects are triggered outside of all time intervals (eg at 01:10.00).

In addition, the effective time interval for each visual effect label can be defined by using the start time plus the length of time, as follows: [00:00.00, 00:55.00] Effect setting data 1 [00:24.00, 01:03.00] Setting data 2 [01:28.00, 03:02.00] Effect setting data 3 [04:30.00, 08:08.00] Effect setting data 4

It can be seen from the above data definition that the effective time interval of the visual effect corresponding to the special effect setting data 1 and the special effect setting data 2 overlaps. Therefore, in the present embodiment, two different visual special effects can be in the same time interval. coexist.

Further, corresponding to the same time interval, there may be multiple visual effects, which may be the same type of visual effects, such as multiple lighting effects, or multiple video overlay effects, or multiple different types of visual effects. Special effects, for example, include both lighting effects and video effects. At this time, the effect setting data set can be as follows: [00:00.00, 00:55.00] Effect setting data 1-1, effect setting data 1-2 [00:24.00, 01:03.00] Effect setting data 2 [01:28.00 , 03:02.00] Effect setting data 3 [04:30.00, 01:08.00] Effect setting data 4-1, effect setting data 4-2.

It can be understood that the setting manner of the above first visual effect label is equivalent to the following manner: [00:00.00, 00:55.00] Special effect setting data 1-1 [00:00.00, 00:55.00] Special effect setting data 1-2

That is, the visual effect label including a plurality of special effects is split into a plurality of visual effect labels having the same effective time interval.

In the various embodiments listed above, the time is represented by time: minute: second. However, the present invention is not limited to this method. For example, any unit such as seconds, milliseconds, minutes, etc. can be directly used. To characterize. Taking the start time 00:24.00 as an example, the number of seconds converted is 1440, and the number of milliseconds is 14.40 million, which is 24 in minutes. The time data recorded in the time setting data can also be the result of various reversible operations on the time value, and even cryptographic operations can be performed. Taking the above number of seconds 1440 as an example, for example, it can be divided by 2 to obtain 720. That is, 720 is stored in the time setting data, but it actually expresses 1440 seconds. It can be understood that after this operation, in order to calculate the effective time interval of a visual effect label, a reverse operation is required to obtain an actual time interval.

It can be understood that, regardless of the processing, the essence is still to define a time starting point or a time interval in the visual effect label, and therefore all of these methods should be included in the range setting data.

The effect setting data can be the original file of video, animation, picture and text.

The effect setting data can be used to set the way to generate visual effects and other parameters. Visual effects here can include static effects as well as dynamic effects. Static effects, for example, can include effects such as light color, light brightness, display patterns, and display text. Dynamic effects include, for example, various animations such as color changes, brightness changes, pattern changes, text changes, animations, or combinations thereof. Dynamic effects can correspond to a single shot or a series of consecutive beats. The animation effects described above, for example, may include superimposed animation effects on the main screen of the chorus multimedia video, such as displaying full-screen flowers, rain, snow, heart-shaped cakes, and the like. The effect setting data can also be information for other formats used to obtain visual effects, such as the identifier of the visual effects resource file. The visual effect resource file here may be pre-stored in the memory connected to the control host 10 or stored in the cloud server. The control host 10 can read the visual special effect resource file corresponding to the identifier of the visual special effect resource file in the memory, or initiate a network request to download the visual special effect resource file from the cloud server.

Preferably, the visual special effect set by the special effect setting data is related to the music beat, and the time node of the beat is controlled by the time setting data described above. In general, the visual effects set by the special effects setting data, for each beat of the music, it is best to output an obvious visual special effect change in the visual special effects, and the amplitude, speed, range and the like of the visual special effect change can be It is related to the characteristics of the beat (by analyzing the audio parameters such as volume and frequency). Therefore, through visual effects, it is possible to reflect the changes in music, so that in addition to sound, music can also give people a richer stimulation through visual effects. In other words, the visual effect of the present embodiment visualizes the music beat and enhances the musical beat feeling.

In the singing visual effect system of the present embodiment, the control host 10 also adjusts the visual effect output by the visual effect device 11 in real time according to the inclination data synchronized by the hand-held tilt sensing element 15.

In a specific embodiment, the control host 10 calculates a change parameter of the visual effect from the tilt according to a pre-stored rule, and changes the current visual effect signal according to the change parameter. For example, the tilt can be correlated to the brightness of the visual effect. That is, a mapping function F(θ) between the inclination θ and the visual effect brightness is established. Thus, the control host 10 adjusts the brightness of the current visual effect signal in real time corresponding to the inclination data of each cycle of the hand-held tilt sensing element 15. The mapping function described above is preferably a continuous function such that the varying parameters continuously change as the tilt angle of the hand tilt assembly 15 changes.

It can be understood that the parameters that can be changed are not limited to brightness, and any display parameters such as contrast, color ratio, and special effect area size may be associated with the inclination, and each change is not limited to changing a display parameter, for example, according to The tilt changes both contrast and brightness, and so on.

In another specific implementation, the visual effect data set includes a tilt response tag, and the tilt response tag defines a manner in which the visual effect signal changes in response to the change of the tilt data in a certain period of time. That is, at different time nodes, the control panel 10 changes the visual effect signal in a different manner (as defined by the tilt response tag).

Since each visual effect label actually corresponds to a time interval, that is, in different time intervals, the visual effect signal will respond differently according to the change of the inclination. For example, in the first visual effects label, the visual effect responds to a change in the tilt, the brightness of which changes, the greater the tilt, the higher or lower the brightness. In the second visual effects label, the visual effect responds to the change in tilt by changing its color. The greater the tilt, the darker the color. In the third visual effects tab, the visual effect responds to the change in tilt, which superimposes the additional animation effects on the basic image of the visual effects. In summary, any display mode and content changes can be used to change the visual effect signal response tilt.

In another specific embodiment, the tilt can be used not only to change visual effects signals, but also to control visual effects signals, such as pausing or continuing to play visual effects signals. Specifically, when the inclination is relatively small or large, the playback of the current visual effect is suspended, and when the inclination exceeds a certain angle or is less than a certain angle, the visual effect preset for the current song is played, or different visual effects are switched. .

In another specific implementation manner, the change characteristic of the inclination in a certain time interval may also be analyzed, and then the operation according to the predetermined mode or the condition is defined to be different, and respectively used to trigger different control events, for example, changing the current Visual effects signals, or control the pause, play or visual effects of visual effects signals.

In another specific embodiment, the inclination is also placed in a three-dimensional coordinate system, such as an XYZ coordinate system, and then the inclination is decomposed into components on three planes, and the components on the three planes can be used separately. In controlling the different parameters in the current visual effect signal, for example, the components on the three planes respectively control the ratio of the three colors of red, green and blue. In this way, the singer can dynamically adjust the visual effects at the same time as singing to match the emotions of the singing, and enhance the richness of the special effects of the singing scene.

According to the singing visual special effects system of the present embodiment, the tilting data of the hand-held tilt sensing component can be used to instantly adjust the current visual special effect, providing the singer with a natural and convenient instant control function, and the visual change due to the continuous change characteristic of the tilt Special effects can also be adjusted continuously and smoothly.

Therefore, referring to FIG. 3, the control host 10 can also display a selection function table when the song is played, prompting the user to switch between different versions of the visual effects.

It can be understood that the prompt function table shown in FIG. 3 is not necessary, and the corresponding visual effect version switching button can be set on the remote controller, and when the switching button is pressed, it can be performed between different visual versions.

The radio frequency module can include various existing circuit components for performing these functions, such as an antenna, a radio frequency transceiver, a digital signal processor, an encryption/decryption chip, a user identity module (SIM) card, a memory, and the like. The RF module can communicate with various networks such as the Internet, intranets, wireless networks or with other devices over a wireless network. The wireless network described above may include a cellular telephone network, a wireless local area network, or a metropolitan area network. The above wireless network can use various communication standards, protocols and technologies, including but not limited to Global System for Mobile Communication (GSM), Enhanced Data GSM Environment (EDGE), wideband code. Wideband code division multiple access (W-CDMA), Code division access (CDMA), time division multiple access (TDMA), wireless fidelity (Wireless, Fidelity, WiFi) (such as the Institute of Electrical and Electronics Engineers Standard IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and / or IEEE 802.11n), Voice over internet protocal (VoIP), Worldwide Interoperability for Microwave Access ( Worldwide Interoperability for Microwave Access, Wi-Max), other agreements for mail, instant messaging and short messages, and any other suitable communication protocols, even those that are not currently under development.

The software program and module described above include an operating system 122 and a visual effects service module 124. The operating system 122 may include various software components and/or drivers for managing system tasks (eg, memory management, storage device control, power management, etc.) and may communicate with various hardware or software components to provide other software. The operating environment of the component. The visual effect service module 124 runs on the basis of the operating system 122 for realizing the transmission control function of the visual special effects data set of the singing visual special effects system, which is described in detail below.

The visual effect service module 124 includes an identity verification module 126, a special effect transmission module 128, and an information transmission module 130.

The identity verification module 126 is configured to perform identity verification on the user side. In a specific implementation, each control host 10 stores identity authentication information, such as an encrypted string of host IDs. Before initiating the visual effect data set acquisition request to the visual effect service module 124, the control host 10 may initiate a login request to send the identity authentication information to the server 24. Correspondingly, the identity verification module 126 of the server 24 decrypts the identity authentication information according to the predetermined encryption algorithm and the key, and verifies whether the host ID has the permission to acquire the visual effect data set. For example, the payment identifier corresponding to the host ID is retrieved. If the host ID does not pay the usage fee of the visual effect data set, the host ID does not have the permission to acquire the visual special effect data set, and the identity authentication of the control host 10 is not transparent. Accordingly, the effect transmission module 128 rejects the request to control the host 10 to obtain the visual effects data set.

If a host ID has permission to obtain a visual effects data set, the effect transmission module 128 returns a corresponding visual effect data set according to the request of the control host 10. It can be understood that the control host 10 can initiate the above-mentioned login verification request and the visual effect data set acquisition request when starting a certain song or other multimedia file, or after the song enters the playlist, and the identifier of the song to be played. It is included in the request for obtaining the visual effects data set mentioned above.

It can be understood that it takes a certain time to download the visual special effects data set from the server 24. Therefore, if the visual effect data set is started to be downloaded when the song starts playing, it needs to be considered when the visual special effects data set is downloaded and the visual special effect is played. Remove the impact of download time on the timeline. Specifically, if the download of the visual effects data set is completed and the playback starts at time T after the song is played, the timeline of the visual effects will start from time T instead of starting from the beginning to synchronize with the timeline of the multimedia file. This requires the control host 10 to record the time when the multimedia file starts to play and the time when the visual effect data set is downloaded. The time difference between the two is the time T described above.

Once each multimedia file is added to the to-be-played list, the control host 10 can begin downloading the corresponding visual effects data set. In this way, only the visual effects data set of the first multimedia file in the playlist needs to adjust the timeline, and the visual effects data set of all subsequent songs can be downloaded in the background while other songs are played, therefore, When you want to play, the visual effects data set has been downloaded, and the visual effects can be played synchronously with video and audio. There is no need to adjust the timeline.

It can be understood that when the song is paused, the control panel synchronization will also pause the visual effects.

The information transmission module 130 is configured to transmit some additional information in addition to the visual effects data set. Specifically, the information transmission module 130 can be used to transmit personalized messages of the user. It can be understood that in order for the information transmission module 130 to transmit the personalized information of the user, the information transmission module 130 needs to know the identity information of the current user.

In a specific implementation manner, the control host 10 itself includes a login module for allowing the user to input a username and password for the login operation, and the control host 10 can receive the user name and password input by the user. Upload it to the cloud server for login verification. If the login verification is passed, the identity information of the currently logged-in user can be included in the network request every time a network request is sent to the cloud server, thereby transmitting the information. The module 130 can transmit the personalized information of the user according to the identity information uploaded by the control host 10.

In another specific implementation manner, the control host 10 may not directly transmit the identity information of the user, but only transmit the identification word of the control host 10 itself. In this way, it is necessary for the cloud server to uniquely determine the corresponding user by controlling the identity of the host 10 itself. That is, if the control host 10 uploads only the identification word of the control host 10 itself, it is necessary to establish a binding relationship between the control host 10 and the current user in advance.

For example, a two-dimensional code is set on the control host 10, in the KTV room in which the control host 10 is located, or on the screen of the television set 14 connected to the control host 10. The QR code may include an encryption of the ID of the control host 10. String. After the user scans the QR code in a specific application, the application initiates a network request to the predetermined URL, and sends the identifier of the current user of the application to the encrypted string. Give server 24. After receiving the network request, the server 24 parses out the user identification information and the host ID, and establishes a binding relationship between the two. Correspondingly, the information transmission module 130 can transmit the personalized information of the user, for example, an avatar, a name, and other information edited by the user to the control host 10.

It can be understood that to achieve replacement of the current multimedia video content, the control host 10 needs to know when and where at the multimedia video home screen the replacement operation is performed. In an embodiment, the control host 10 can perform a face recognition operation, and when the face is recognized in the played multimedia video screen, the face can be replaced with the current user's face.

In another method, the visual effect data set includes a video replacement special effect label, and the video replacement special effect label includes time setting data, and the shape data of the area defined by the predetermined shape in the main screen of the multimedia video. And category information corresponding to the shape data. The video replacement effect label can be predetermined. The shape data defines an area to be replaced by video or text, and the category data defines a category of information to be replaced in a certain area, for example, a user personalized information that is replaced with a user image or a user name or any other category. In this manner, the visual effects data set includes a video replacement effect tag for generating a video replacement effect synchronized with the timeline in addition to the visual effect tag for generating the singing visual effect as described in the above embodiments.

Thus, the control host 10 can display the personalized information of the user on the main screen or in the LED array. For example, replace the avatar in the main screen with the avatar of the user, or replace the text in the main screen with the user name. It can be understood that in order to prevent leakage of user information, it is necessary to implement the unbinding operation between the user and the control host 10 after the user leaves the current user room.

In one embodiment, whenever the control host 10 is rebooted, an unbinding request is sent to the server 24 to release all user bindings to the control host 10. This solution is based on the fact that all singing visual effects systems are restarted before they are used by different users.

In another embodiment, the binding relationship between the control host 10 and the user can be released by the user using the application used in the binding. Therefore, user information leakage can be avoided.

According to the singing visual special effect system of the embodiment, the visual special effect data set is stored in the cloud server system 20, which ensures that the visual special effect data set can be accessed only by the authorized user, and the security of the visual special effect data set is improved.

In this embodiment, the external device 40 is, for example, a host in a conventional multimedia playing system, which implements a song control function of a song and a song. However, it is further connected to the control host 10 than the conventional multimedia playback system. Whenever the external device 40 plays a song or a song is added to the playlist, the external device 40 transmits the identification of the song to the control host 10.

It can be understood that in order for the external device 40 to send specific information to the control host 10, a specific application design development interface (API) can be disclosed in the control host 10, so that the external device 40 can be called to send to the control host 10. The above information. Whenever the external device 40 plays a song, the external device 40 can submit the identification of the song and the time when the playback starts to the control host 10 through the API described above. Of course, in order to implement the API call, the external device 40 needs to modify the program in the existing external device 40 so that the information is synchronized with the control host 10 through the API when needed.

Correspondingly, the control host 10 requests the cloud server system 20 to acquire the visual effect data set according to the identifier of the song. It will be appreciated that the control host 10 can also perform authentication operations as described in the previous embodiments. After obtaining the visual special effects data set, the control host 10 generates a corresponding video special effect signal according to the visual special effect label in the visual special effect data set, and sends the generated visual special effect signal to the special effect device 26. Of course, considering the delay of the network download, the control host 10 can also perform the time adjustment of the visual effects, that is, apply a forward offset to the time defined by the time setting data, so that the timeline and the file of the visual effects are played. The progress is synchronized.

The effect device 26 superimposes the visual effect signal on the main screen of the multimedia video output device 14 and/or outputs it to the visual effect output device 11.

According to the singing visual special effect system of the present embodiment, by slightly improving the software of the external device 40 in the existing multimedia playing system, the visual effect synchronized with the song can be added, and the device in the existing multimedia playing system can be compatible to the greatest extent. To avoid the cost increase caused by equipment upgrades.

Although the above embodiment is described by taking the KTV system as an example, the above-described singing visual effects system can also be applied to multimedia classrooms, dance halls, and park entertainment facilities.

In particular, when the control host 10 is a smart electronic device (such as a smart phone), the software installed in the smart electronic device can wirelessly control the visual effect output device 11 or wirelessly access the visual effects on the network. At the same time, the songs played through the external device 40 are recorded through the built-in microphone, and the songs placed by the external device 40 are directly recognized through feature sampling and feature matching, so that the songs can be obtained without communication with the external device 40. Identify and then download the corresponding visual effects data set to play visual effects in sync with the song.
