[0055] In related technologies, when multiple screens simultaneously display digital humans and other images, the hardware performance requirements of the display control device are very high, especially in high-definition display mode, where the hardware performance of the display control device cannot support the simultaneous display of multimedia resources and the operation of 3D digital humans. To address this issue, this embodiment provides a method for displaying digital humans on multiple screens. This method can be applied to various display scenarios that require the simultaneous display of digital humans and another image (i.e., the first image) through multiple screens. The digital human mentioned in this invention is a 3D digital human.

[0056] For example, it can be applied to song-on-demand scenarios in digital entertainment venues, simultaneously displaying digital humans and music videos on multiple screens; it can also be applied to stage displays for various performances, where multiple screens are used to display stage backgrounds, background videos, and digital humans related to the performance content. This method of displaying digital humans on multiple screens involves collaborative processing by two or more devices to adapt the first image and digital human to the display specifications of the multiple screens, reducing the hardware performance requirements of the display control equipment and making the multi-screen display clearer and smoother.

[0057] Please see Figure 1 This embodiment describes a method for displaying a digital human on multiple screens, comprising the following steps:

[0058] S101, The first device analyzes the signals of the first image and the digital human.

[0059] S102. The first device arranges the first image and the digital human according to the display specifications of the multi-screen and the position and / or proportion of the first image and the digital human displayed on the multi-screen, so that the first image and the digital human are both located within the display area of ​​the multi-screen. The arrangement includes scaling and translation.

[0060] S103, The first device sends the display information about the first image and the digital human obtained after layout to the second device;

[0061] S104. The second device trims the display information according to the display specifications of the multi-screen display to remove blank areas in the display information.

[0062] S105, the second device sends the cropped display information to the multi-screen display for display.

[0063] In step S101, the first image can be any static image or dynamic video selected according to display needs. The digital human runs on the first device, meaning the digital human is generated using the hardware and software resources of the first device, and can be displayed on the layout interface of the first device. The digital human refers to a virtual character created using digital technology, which can exhibit physiological, psychological, or social characteristics similar to real humans. The parsing of the signals of the first image and the digital human refers to decoding the signals of the first image and the digital human according to the display settings of the first device to obtain display data with a certain aspect ratio. The first image can be displayed on the layout interface of the first device. During decoding, the first device also performs the above decoding according to the display requirements of a multi-screen setup, so that the decoded data meets the display requirements of the multi-screen setup. For example, the first device decodes the signal of the first image to the corresponding resolution (e.g., 4K or 8K resolution) according to the resolution requirements of the multi-screen setup.

[0064] This invention runs the digital human directly on a first device, which then outputs sound signals and digital human images to a second device, ensuring that the digital human's speech matches the lip-syncing images. If the digital human is run on the second device, the sound signal output from the first device may not match the lip-syncing images output by the second device.

[0065] In step S102, the display specifications of the multi-screen refer to the aspect ratio of the multi-screen. Under normal circumstances, the display specifications of the multi-screen include any one of 4:3, 5:4, 16:10, 21:9, and 16:9. In some other embodiments, the display specifications of the multi-screen can be other custom aspect ratios.

[0066] In step S102, the display position and display ratio (i.e. display size) of the digital human on the multi-screen can be determined first. Then, based on the display position and ratio of the digital human on the multi-screen, the first image is scaled and translated so that the first image and the digital human are displayed completely and without distortion to fit the display size of the multi-screen.

[0067] The digital human is displayed at one end of the length of the multi-screen display, and occupies 1 / N of the area of ​​the multi-screen display, where N is a positive integer greater than 2; the first image occupies (N-1) / N of the multi-screen display.

[0068] The layout of the first image and the digital human includes:

[0069] The length and width of the digital human are reduced to 1 / N of the layout interface of the first device, where N is a positive integer greater than 2; the reduced digital human is then placed at one end of the length direction of the multi-screen display.

[0070] The length and width of the first image are reduced to (N-1) / N of the layout interface of the first device; and the reduced first image is translated to the other end of the length direction of the multi-screen.

[0071] like Figure 2 As shown, in one embodiment, the digital human is displayed on the right side of a multi-screen display (if the multi-screen display consists of multiple horizontally spliced ​​displays, the digital human is displayed on the last or several displays of the multi-screen display), and the length and width of the digital human occupy 1 / 4 of the layout interface of the first device. The digital human is first moved to the far right of the layout interface, then the length and width of the first image are scaled to 3 / 4 of the layout interface of the first device, and finally the scaled first image is moved to the far left of the layout interface to be spliced ​​with the left side of the digital human. Then, it is transmitted to the second device via an HDMI cable or other high-speed video transmission cable.

[0072] In other embodiments, the digital human may also be displayed at the far left or top of the multi-screen display, with its length and width occupying 1 / 3 or other proportions on the layout interface. For example, when the digital human is displayed at the left end of the multi-screen display, and its display area is 1 / 3, the digital human is first moved to the far left of the layout interface, and the length and width of the first image are scaled to 2 / 3 of the layout interface. Finally, the scaled first image is moved to the far right of the layout interface and stitched together with the left side of the digital human. The layout methods for other proportions and display positions of the digital human on the multi-screen display are similar to the 1 / 3 and 1 / 4 layout methods described above, and will not be repeated here.

[0073] like Figure 2 As shown, in the display image corresponding to the display information after layout in step S102, there will be blank areas around the first image and the digital human. Therefore, in step S103, these blank areas are cropped by the second device to obtain display information that is compatible with the display specifications of the multi-screen display.

[0074] In one embodiment, in addition to sending the display information about the first image and the digital human obtained after the layout to the second device, the first device also sends control information to the second device. The second device generates a second image according to the control information and switches between displaying the digital human or the second image in the display area of ​​the digital human. The second image includes any one of the following: a mirror image of the first image, a partial mirror image of the first image, or other special effects images.

[0075] The control information is used to control the display content of the area where the digital human is located on the multi-screen display. That is, the second device can switch between displaying the digital human or other images on the multi-screen display by executing the control information. Figure 3 As shown, for example, in some cases, the digital human is not displayed on the multi-screen display; instead, a mirror image of the first image or a partial view of the first graphic is displayed in the digital human display area. When the first image is a music video (MV), a mirror image of the MV or a partial view of the MV is displayed in the original display area where the digital human was displayed. Figure 4 As shown, in other embodiments, the second image displayed in the digital human display area can be another image selected as needed.

[0076] like Figure 5 As shown, for example, in some cases, although the layout interface of the first device displays a digital human, the digital human is not displayed on the multi-screen display. Instead, a mirror image of the first image or a mirror image of a partial view of the first graphic is displayed in the digital human display area. When the first image is a music video, a mirror image of the music video or a mirror image of a partial view of the music video is displayed in the original display area where the digital human is displayed.

[0077] In one embodiment, the first device is a multimedia on-demand device, and the second device is a display control device for the multi-screen setup; the first image is a music video (MV) of a song being played. The multimedia on-demand device is equipped with a multimedia on-demand system, through which multimedia resources such as songs, movies, and games can be searched and played. The first device sends the display information to the second device via an HDMI cable, and the first device sends the control information to the second device via a network or serial port. The multi-screen setup is a four-screen setup formed by splicing four displays together, and the display specifications of the multi-screen setup are 16:9 or other aspect ratios. The following provides a detailed description of displaying digital figures and music videos on the multi-screen setup in this specific embodiment, which includes the following steps:

[0078] 1. For the display specifications of a four-screen (i.e., multi-screen) setup, the multimedia on-demand device (i.e., the first device) will reduce the size of the music video (i.e., the first image) of the currently played song, so that the display area of ​​the music video is reduced to 3 / 4 of the full screen size.

[0079] 2. Based on the position of the digital human on the four-screen display (screen 4), shift the display area of ​​the MV to the left, leaving approximately 1 / 4 of the area for the digital human display;

[0080] 3. For example Figure 2 As shown on the left side, after steps 1 and 2, the video of the song's music video is concentrated in 3 / 4 of the original full-screen area.

[0081] The 4 multimedia on-demand device (i.e., the first device) transmits the processed image to the display control device of the four-screen setup (i.e., the second device) via HDMI cable, and at the same time sends instructions to the display control device, which contain the control information of the image.

[0082] 5. The display control device crops the transmitted image, removing areas without display content;

[0083] 6. The display control device further processes the screen based on the control information, for example:

[0084] 1) such as Figure 2 As shown, when a digital human is displayed on the 4th screen, the white area with no displayed content is cropped out:

[0085] 2) When the digital human is not displayed on the 4th screen, a mirror image of a portion of the MV is displayed on the 4th screen.

[0086] In this embodiment, the digital human runs on a multimedia on-demand device (i.e., the song request terminal). The multimedia on-demand device rearranges and lays out the output screen, allowing the digital human and the song's music video to be perfectly displayed simultaneously on multiple screens without image distortion or missing parts. Furthermore, by having the multimedia on-demand device and the display control device collaboratively share the information processing tasks for the music video and the digital human, the hardware performance requirements of the display control device are greatly reduced, resulting in smoother image display on multiple screens. In this embodiment, music video mirroring is implemented on the display control device, and through control information (i.e., wake-up commands), the display of the music video mirror or the digital human on the fourth screen can be dynamically controlled. Through the cooperation of these two devices, the problem of insufficient performance of the four-screen display control device to run the digital human is solved, while also addressing the issue of display mirroring in a four-screen environment.

[0087] like Figure 6 As shown, in another embodiment, a display device 400 for displaying a digital human on multiple screens is provided. The display device 400 for displaying a digital human on multiple screens includes a first device 401 and a second device 402. The first device 401 and the second device 402 can be connected via an HDMI cable and / or a network and / or a serial port, and the second device 402 and the multiple screens 403 are also connected via another HDMI cable.

[0088] The first device 401 is used to analyze the signals of the first image and the digital human, and to arrange the first image and the digital human according to the display specifications of the multi-screen 403 and the position and / or proportion of the first image and the digital human displayed on the multi-screen, so that the first image and the digital human are both located within the display area of ​​the multi-screen, the arrangement including scaling and translation; and to send the display information about the first image and the digital human obtained after arrangement to the second device.

[0089] The second device 402 is used to crop the display information according to the display specifications of the multi-screen 403 to remove blank areas in the display information; and to send the cropped display information to the multi-screen for display.

[0090] In the above embodiment, the digital human is displayed at one end of the length direction of the multi-screen, and occupies 1 / N of the area of ​​the multi-screen, where N is a positive integer greater than 2; the first image occupies (N-1) / N of the multi-screen.

[0091] The layout of the first image and the digital human includes:

[0092] The length and width of the digital human are reduced to 1 / N of the layout interface of the first device, where N is a positive integer greater than 2; the reduced digital human is then placed at one end of the length direction of the multi-screen display.

[0093] The length and width of the first image are reduced to (N-1) / N of the layout interface of the first device; and the reduced first image is translated to the other end of the length direction of the multi-screen.

[0094] The first device also sends control information to the second device;

[0095] The second device generates a second image based on the control information, and switches between displaying the digital human or the second image in the display area of ​​the digital human. The second image includes any one of the following: a mirror image of the first image, a partial mirror image of the first image, or other special effects images.

[0096] The first device is a multimedia on-demand device, and the second device is the display control device for the multi-screen setup; the first image is the music video of the on-demand song; the first device sends the display information to the second device via an HDMI cable, and the first device sends the control information to the second device via a network or serial port.

[0097] Running the 3D digital human on a multimedia on-demand device (i.e., the song request terminal), the output screen is rearranged and laid out through the multimedia on-demand device, allowing the digital human and the song's music video to be perfectly displayed simultaneously on multiple screens without image distortion or missing parts. Furthermore, by having the multimedia on-demand device and the display control device collaborate to share the information processing tasks of the music video and the digital human, the hardware performance requirements of the display control device are greatly reduced, resulting in smoother image display on multiple screens. In this embodiment, music video mirroring is implemented on the display control device, and through control information (i.e., wake-up commands), the display of the music video mirror or the digital human on the fourth screen can be dynamically controlled. Through the cooperation of the two devices, the problem of insufficient performance of the four-screen display control device to run the digital human can be solved, while also addressing the issue of display mirroring in a four-screen environment.

[0098] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
