[0051] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.

[0052] The embodiment of the present application provides a video display method, specifically as follows: Figure 1 As shown, the method includes:

[0053] 101. Obtain a video signal to be displayed.

[0054] In an embodiment of the present application, the execution entity in each step is a target terminal device comprising multiple display screens, wherein the target terminal device may be, but is not limited to, a television, a computer, etc., the display area sizes of the multiple display screens are the same, the resolutions of the multiple display screens are the same, and the resolutions of the multiple display screens may be, but are not limited to, 1080P, 2K, 4K, etc.

[0055] In an embodiment of the present application, the target terminal device is connected to a set-top box (STB). After the set-top box obtains the signal of the video to be displayed, it sends the signal of the video to be displayed to the target terminal device. At this time, the target terminal device can obtain the signal of the video to be displayed (i.e., the video signal to be displayed).

[0056] 102. Divide the video signal to be displayed into a first video stream corresponding to each preset signal channel.

[0057] Among them, the first video streams corresponding to the various preset signal channels are exactly the same; the number of the multiple preset signal channels is the same as the number of the multiple display screens included in the target terminal device, and the multiple preset signal channels correspond one-to-one to the multiple display screens.

[0058] In the embodiment of the present application, after the target terminal device obtains the video signal to be displayed, it needs to split the video signal to be displayed into video streams corresponding to each preset signal channel (ie, first video stream).

[0059] Specifically, in this step, the target terminal device may split the video signal to be displayed into the first video stream corresponding to each preset signal channel through a hub.

[0060] 103. Perform segmentation and capture processing on the first video stream corresponding to each preset signal channel to obtain a second video stream corresponding to each preset signal channel.

[0061] Among them, for any preset signal channel, each video image frame contained in the second video stream corresponding to the preset signal channel is a part of the corresponding video image frame contained in the first video stream, the resolution of each video image frame contained in the second video stream corresponding to the preset signal channel is the same as the resolution of the display screen corresponding to the preset signal channel, and the image size of each video image frame contained in the second video stream corresponding to the preset signal channel is the same as the display area size of the display screen corresponding to the preset signal channel.

[0062] In an embodiment of the present application, after the target terminal device diverts the video signal to be displayed into the first video stream corresponding to each preset signal channel, it needs to segment and capture the first video stream corresponding to each preset signal channel to obtain the second video stream corresponding to each preset signal channel.

[0063] 104. Send the second video stream corresponding to each preset signal channel to the display screen corresponding to each preset signal channel, so that each display screen outputs and displays the corresponding second video stream.

[0064] In an embodiment of the present application, after the target terminal device obtains the second video stream corresponding to each preset signal channel, it can send the second video stream corresponding to each preset signal channel to the display screen corresponding to each preset signal channel, so that each display screen outputs and displays its corresponding second video stream, thereby achieving the effect of displaying high-resolution video through multiple low-resolution display screens.

[0065] For example, the target terminal device includes four display screens, namely display screen A, display screen B, display screen C, and display screen D, wherein the resolution of the four display screens is 4K, display screen B is placed on the right side of display screen A, display screen C is placed below display screen A, and display screen D is placed on the right side of display screen C. The preset signal channel a corresponds to display screen A, the preset signal channel b corresponds to display screen B, the preset signal channel c corresponds to display screen C, and the preset signal channel d corresponds to display screen D;

[0066] After the first video stream corresponding to each preset signal channel is segmented and captured, the second video stream a corresponding to the preset signal channel a, the second video stream b corresponding to the preset signal channel b, the second video stream c corresponding to the preset signal channel c and the second video stream d corresponding to the preset signal channel d are obtained; wherein, in the process of segmenting and capturing the first video stream corresponding to each preset signal channel, the following steps are: based on the line connecting the midpoints of the two long sides and the midpoints of the two wide sides of each video image frame contained in the first video stream, each video image frame contained in the first video stream corresponding to each preset signal channel is segmented into four parts of the same size, so that the multiple video images contained in the second video stream a The image frame is the upper left part of each video image frame contained in the first video stream corresponding to the preset signal channel a, the multiple video image frames contained in the second video stream b are the upper right part of each video image frame contained in the first video stream corresponding to the preset signal channel b, the multiple video image frames contained in the second video stream c are the lower left part of each video image frame contained in the first video stream corresponding to the preset signal channel c, and the multiple video image frames contained in the second video stream d are the lower right part of each video image frame contained in the first video stream corresponding to the preset signal channel d. The resolution of the first video stream is 8K, and the resolutions of the second video stream a, the second video stream b, the second video stream c, and the second video stream d are all 4K;

[0067] The second video stream a is sent to display screen A so that display screen A outputs and displays the second video stream a, the second video stream b is sent to display screen B so that display screen B outputs and displays the second video stream b, the second video stream c is sent to display screen C so that display screen C outputs and displays the second video stream c, and the second video stream d is sent to display screen D so that display screen D outputs and displays the second video stream d; wherein, since the resolution of the second video stream output and displayed by each display screen is 4K, the resolution of the video composed of the second video streams output and displayed by multiple display screens (i.e., the video to be displayed) is 8K, thereby achieving the effect of displaying high-resolution video through multiple low-resolution display screens.

[0068] An embodiment of the present application provides a video display method. After a target terminal device including multiple display screens obtains a video signal to be displayed, the embodiment of the present application can divert the video signal to be displayed into a first video stream corresponding to each preset signal channel, and segment and capture the first video stream corresponding to each preset signal channel to obtain a second video stream corresponding to each preset signal channel. Finally, the second video stream corresponding to each preset signal channel is sent to the display screen corresponding to each preset signal channel, so that each display screen outputs and displays its corresponding second video stream, thereby achieving the effect of displaying high-resolution video through multiple low-resolution display screens, thereby reducing the cost for users to watch high-resolution videos.

[0069] To illustrate in more detail below, the present application provides another video display method, specifically as follows: Figure 2 As shown, the method includes:

[0070] 201. Obtain a video signal to be displayed.

[0071] Regarding step 201, obtaining the video signal to be displayed, please refer to Figure 1 The description of the corresponding parts will not be repeated here in the embodiments of this application.

[0072] 202. Divide the video signal to be displayed into a first video stream corresponding to each preset signal channel.

[0073] Regarding step 202, dividing the video signal to be displayed into the first video stream corresponding to each preset signal channel, reference may be made to Figure 1 The description of the corresponding parts will not be repeated here in the embodiments of this application.

[0074] 203. Perform segmentation and capture processing on the first video stream corresponding to each preset signal channel to obtain a second video stream corresponding to each preset signal channel.

[0075] In an embodiment of the present application, after the target terminal device diverts the video signal to be displayed into the first video stream corresponding to each preset signal channel, it needs to segment and capture the first video stream corresponding to each preset signal channel to obtain the second video stream corresponding to each preset signal channel.

[0076] Specifically, in this step, for any preset signal channel, the target terminal device may segment and capture the first video stream corresponding to the preset signal channel in the following manner to obtain the second video stream corresponding to the preset signal channel:

[0077] (1) Segmenting the plurality of first video image frames corresponding to the preset signal channel according to a preset rule to obtain a segmentation result corresponding to each first video image frame.

[0078] The first video stream corresponding to the preset signal channel includes a plurality of first video image frames.

[0079] Among them, the preset rules are set in advance according to the number of multiple display screens contained in the target terminal device and the placement positions of the multiple display screens. For example, when the target terminal device contains four display screens (specifically: display screen A, display screen B, display screen C and display screen D, preset signal channel a corresponds to display screen A, preset signal channel b corresponds to display screen B, preset signal channel c corresponds to display screen C, preset signal channel d corresponds to display screen D), the placement positions of the four display screens are specifically: display screen B is placed on the right side of display screen A, display screen C is placed below display screen A, and display screen D is placed on the right side of display screen C. The preset rules are specifically: when the first video stream corresponding to each preset signal channel is segmented and captured, first, based on the line connecting the midpoints of the two long sides and the midpoints of the two wide sides of each first video image frame contained in the first video stream, Connect the lines, divide each first video image frame contained in the first video stream corresponding to each preset signal channel into four parts of the same size (that is, the segmentation results corresponding to each first video image frame), and then capture the upper left part of the segmentation result of each first video image frame corresponding to the preset signal channel a to obtain multiple second video image frames corresponding to the preset signal channel a, capture the upper right part of the segmentation result of each first video image frame corresponding to the preset signal channel b to obtain multiple second video image frames corresponding to the preset signal channel b, capture the lower left part of the segmentation result of each first video image frame corresponding to the preset signal channel c to obtain multiple second video image frames corresponding to the preset signal channel c, and capture the lower right part of the segmentation result of each first video image frame corresponding to the preset signal channel d to obtain multiple second video image frames corresponding to the preset signal channel d.

[0080] In an embodiment of the present application, the target terminal device first needs to perform segmentation processing on the multiple first video image frames corresponding to the preset signal channel according to a preset rule, so as to obtain a segmentation result corresponding to each first video image frame.

[0081] (2) The segmentation result corresponding to each first video image frame is captured and processed according to a preset rule to obtain a second video image frame corresponding to each first video image frame.

[0082] In an embodiment of the present application, after obtaining the segmentation result of each first video image frame corresponding to the preset signal channel, the target terminal device can capture and process the segmentation result corresponding to each first video image frame according to the preset rules, thereby obtaining the second video image frame corresponding to each first video image frame.

[0083] (3) Stretching the plurality of second video image frames according to the display area size of the display screen corresponding to the preset signal channel to obtain a third video image frame corresponding to each second video image frame.

[0084] In an embodiment of the present application, after the target terminal device obtains multiple second video image frames corresponding to the preset signal channel, it needs to stretch the multiple second video image frames according to the display area size of the display screen corresponding to the preset signal channel, so as to obtain a third video image frame corresponding to each second video image frame.

[0085] (4) Performing synthesis processing on the plurality of third video image frames to obtain a second video stream corresponding to the preset signal channel.

[0086] In an embodiment of the present application, after obtaining multiple third video image frames corresponding to the preset signal channel, the target terminal device can synthesize the multiple third video image frames to obtain the second video stream corresponding to the preset signal channel.

[0087] Specifically, in this step, when the resolution of multiple third video image frames is equal to the resolution of the display screen corresponding to the preset signal channel, the multiple third video image frames can be directly synthesized to obtain the second video stream corresponding to the preset signal channel; when the resolution of multiple third video image frames is smaller than the resolution of the display screen corresponding to the preset signal channel, the multiple third video image frames need to be optimized to improve the resolution of each third video image frame, and then the multiple optimized third video image frames are synthesized to obtain the second video stream corresponding to the preset signal channel; wherein, the multiple third video image frames can be optimized based on artificial intelligence image super-resolution technology, and the resolution of the optimized third video image frames is equal to the resolution of the display screen corresponding to the preset signal channel.

[0088] 204. Send the second video stream corresponding to each preset signal channel to the display screen corresponding to each preset signal channel, so that each display screen outputs and displays the corresponding second video stream.

[0089] In an embodiment of the present application, after the target terminal device obtains the second video stream corresponding to each preset signal channel, it can send the second video stream corresponding to each preset signal channel to the display screen corresponding to each preset signal channel, so that each display screen outputs and displays its corresponding second video stream, thereby achieving the effect of displaying high-resolution video through multiple low-resolution display screens.

[0090] Specifically, in this step, when the target terminal identifies and receives the receiving selection instruction sent by the user through the input device (wherein the selection instruction contains a unique identifier corresponding to at least one target preset signal channel), the target terminal device needs to send the second video stream corresponding to each target preset signal channel to the display screen corresponding to each target preset signal channel, so that each display screen outputs and displays its corresponding second video stream, thereby achieving the effect of the user selecting the designated display screen to output and display its corresponding second video stream; when the target terminal identifies that it has not received the receiving selection instruction sent by the user through the input device, the target terminal device needs to send the second video stream corresponding to each preset signal channel to the display screen corresponding to each preset signal channel, so that each display screen outputs and displays its corresponding second video stream.

[0091] like Figure 3 As shown, the target terminal device includes four display screens, namely display screen TV01, display screen TV02, display screen TV03 and display screen TV04, wherein the resolution of the four display screens is 4K, display screen TV02 is placed on the right side of display screen TV01, display screen TV04 is placed below display screen TV01, and display screen TV03 is placed on the right side of display screen TV04. The preset signal channel Out1 corresponds to display screen TV01, the preset signal channel Out2 corresponds to display screen TV02, the preset signal channel Out3 corresponds to display screen TV03, and the preset signal channel Out4 corresponds to display screen TV04;

[0092] After segmenting and capturing the first video stream corresponding to each preset signal channel, a second video stream 01 corresponding to the preset signal channel Out1, a second video stream 02 corresponding to the preset signal channel Out2, a second video stream 04 corresponding to the preset signal channel Out3, and a second video stream 03 corresponding to the preset signal channel Out4 are obtained;

[0093] The resolution of the first video stream is 4K. For any preset signal channel, the process of segmenting and capturing the first video stream corresponding to the preset signal channel is as follows: based on the line connecting the midpoints of the two long sides and the midpoints of the two wide sides of each first video image frame contained in the first video stream, each first video image frame contained in the first video stream corresponding to the preset signal channel is segmented into four parts of the same size (i.e., segmentation results); then, from the segmentation results corresponding to each first video image frame, multiple second video image frames corresponding to the preset signal channel are captured; the multiple second video image frames are stretched according to the display area size of the display screen corresponding to the preset signal channel to obtain third video image frames corresponding to each second video image frame; and the multiple third video image frames are optimized based on artificial intelligence image super-resolution technology to increase the resolution of each third video image frame to 4K. Finally, the multiple optimized third video image frames are synthesized to obtain the second video stream corresponding to the preset signal channel. Therefore, the resolutions of the obtained second video stream 01, second video stream 02, second video stream 04, and second video stream 03 are all 4K.

[0094] The second video stream 01 is sent to the display screen TV01 so that the display screen TV01 outputs and displays the second video stream 01, the second video stream 02 is sent to the display screen TV02 so that the display screen TV02 outputs and displays the second video stream 02, the second video stream 03 is sent to the display screen TV03 so that the display screen TV03 outputs and displays the second video stream 03, and the second video stream 04 is sent to the display screen TV04 so that the display screen TV04 outputs and displays the second video stream 04; wherein, since the resolution of the second video stream output and displayed by each display screen is 4K, the resolution of the video composed of the second video streams output and displayed by multiple display screens (i.e., the video to be displayed) is 8K, thereby achieving the effect of displaying high-resolution video through multiple low-resolution display screens.

[0095] In order to achieve the above-mentioned purpose, according to another aspect of the present application, an embodiment of the present application further provides a storage medium, wherein the storage medium includes a stored program, wherein when the program is running, the device where the storage medium is located is controlled to execute the above-mentioned video display method.
