[0057] Embodiment 1

[0058] Please refer to Figure 2 , Embodiment 1 of the present invention is: a multifunctional control device, which can be applied to audio-visual places, such as Figure 2 As shown, it includes a system management module 1, a display module and a hosting module 5, wherein the display module includes an LED display module 2, a multi-screen display module 3 and a projection ring screen display module 4.

[0059] After booting up, the system management module 1 can obtain the box function configuration file, which includes the number of available display devices; then, according to the box function configuration file, a virtual screen corresponding to each available display device is constructed. In this embodiment, the virtual screen corresponding to the LED display device is used as the first virtual screen, the virtual screen corresponding to the multi-screen display device is used as the second virtual screen, and the virtual screen corresponding to the projection ring screen display device is used as the third virtual screen.

[0060] Among them, the box function configuration file is generated in advance according to the number of display devices (i.e., LED display devices, multi-screen display devices, and projection ring screen display devices) in the box, and each box corresponds to a box function configuration file. For example, assuming that 2 LED display devices, 3 projection ring screen display devices, and 4 multi-screen display devices are set in a box, the system management module will construct 2 first virtual screens, 4 second virtual screens, and 3 third virtual screens. At the same time, the 2 LED display devices can display the same or different materials respectively, or display one material in combination; the 3 projection ring screen display devices can display one display material in combination, or display different or the same materials separately, and the 4 multi-screen display devices can display the same or different materials respectively, or display one material in combination. In a preferred embodiment, if the number of boxes in a venue is relatively small, the box function configuration file can be configured for all boxes in the same venue.

[0061] The system management module 1 can also obtain a song linkage configuration file and a box scene linkage configuration file. The song linkage configuration file includes the association between the song type, display module and material information. The box scene linkage configuration file includes the association between the scene type, display module and material information, wherein the material information includes at least one of a material number and a material type.

[0062] That is to say, the song linkage configuration file indicates the material information to be displayed by each display module for different song types. For example, if the song currently being played is a DJ song, the material type corresponding to the projection ring screen display module is the dynamic type, and the material type corresponding to the multi-screen display module is the propulsion type.

[0063] Similarly, the box scene linkage configuration file indicates the material information to be displayed by each display module for different scene types. For example, if the current scene is DJing, the material type corresponding to the projection ring screen display module is dynamic type, and the material type corresponding to the multi-screen display module is propulsive type. If the current scene is business, the material types corresponding to the projection ring screen display module and the multi-screen display module are both soft types.

[0064] During the use of the box, the on-demand system transmits the song request information to the system management module 1 of the multi-function control device through the protocol. The system management module 1 can determine the song type of the current song based on the song request information, and then determine the material information corresponding to the current song type of each display module based on the song linkage configuration file, and obtain the corresponding material to be displayed for each display module based on the material information corresponding to each display module.

[0065] Alternatively, the system management module 1 may also obtain scene information from the on-demand system, and determine the scene type of the current box scene based on the scene information, and then determine the material information corresponding to the scene type of each display module based on the box scene linkage configuration file, and obtain the material to be displayed corresponding to each display module based on the material information corresponding to each display module.

[0066] After determining the materials to be displayed corresponding to each display module, each display module can obtain the corresponding materials to be displayed, process them and output them to the display interface of the corresponding display device. In this embodiment, the materials to be displayed corresponding to the LED display module 2 are used as the first materials to be displayed, the materials to be displayed corresponding to the multi-screen display module 3 are used as the second materials to be displayed, and the materials to be displayed corresponding to the projection ring screen display module 4 are used as the third materials to be displayed.

[0067] Specifically, the LED display module 2 obtains the first material to be displayed, and intercepts the first material to be displayed to obtain a first material area corresponding to each first virtual screen; then the first material area can be processed, and finally each first material area is output one-to-one to the display interface of the display device corresponding to each first virtual screen.

[0068] Among them, the material processing includes at least one of mirroring, blurring, rotating, dithering and RGB channel separation. In this embodiment, the first material to be displayed can be cropped by a shader to adapt to various irregular resolutions of the LED display screen. The first material to be displayed can be intercepted at any size, and then the first material area can be adapted according to the screen size of the corresponding LED display device; if the size of the first material area is smaller than the screen size of the corresponding LED display device, it can be displayed in the center with black around it. In other embodiments, it can also be displayed in other forms. The LED display device can be an LED display.

[0069] The multi-screen display module 3 obtains the second material to be displayed, and then outputs the second material to be displayed to the display interface of the display device corresponding to each second virtual screen.

[0070] In another optional embodiment, after the multi-screen display module 3 obtains the second material to be displayed, it divides the second material to be displayed according to the number of second virtual screens, obtains second material areas corresponding to each second virtual screen, and outputs each second material area to the display interface of the display device corresponding to each second virtual screen in a one-to-one correspondence. At this time, the screen of each multi-screen display device displays a part of the second material to be displayed, and all display screens are combined to jointly display the second material to be displayed.

[0071] Furthermore, before outputting, the multi-screen display module 3 can also perform material processing on the second material to be displayed or the second material area. As above, the material processing includes at least one of mirroring, blurring, rotating, shaking and RGB channel separation.

[0072] Furthermore, when the screens of the multi-screen display device are spliced ​​in portrait mode, the aspect ratio of the second material to be displayed may be converted from 16:9 to 9:16.

[0073] The projection ring screen display module 4 obtains the third material to be displayed, and divides the third material to be displayed according to the number of third virtual screens to obtain third material areas corresponding to each third virtual screen; and outputs each third material area one-to-one to the display interface of the display device corresponding to each third virtual screen.

[0074] Furthermore, before outputting the third material area, the projection ring screen display module 4 may perform material processing on the third material area. When the projection area corresponding to the projection ring screen display device is a curved screen, the projection ring screen display module 4 may also perform shape correction, fusion transition and mask processing on the third material area to ensure a better display effect. The projection ring screen display device may be a projector.

[0075] Furthermore, the system management module 1 is also used to receive external input operation instructions and forward them to the corresponding modules.

[0076] In this embodiment, the external input operation instruction includes a dimming instruction, that is, the system management module 1 can receive a DMX512 message sent by an intelligent control device (an intelligent control device is a device that outputs control signals specifically for lights, which can control the light to shake, rotate, color, etc.), that is, a dimming instruction, and then obtain the first dimming instruction corresponding to the LED display module 2, the second dimming instruction corresponding to the multi-screen display module 3, and the third dimming instruction corresponding to the projection ring screen display module 4 from the dimming instruction according to the preset offset address corresponding to the LED, the offset address corresponding to the multi-screen, and the offset address corresponding to the projection ring screen, and distribute the first dimming instruction, the second dimming instruction, and the third dimming instruction to the LED display module 2, the multi-screen display module 3, and the projection ring screen display module 4 one by one, respectively, so that the LED display module 2, the multi-screen display module 3, and the projection ring screen display module 4 respectively respond to the corresponding dimming instruction, thereby realizing linkage with the light, and the linkage effects include color change, strobe, splitting, etc. The dimming instructions corresponding to the three display modules can be the same or different from each other.
