DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0052] The following is combined with Figures 1 to 3 This application is described in further detail.

[0053] In order to accurately distribute video data to each display when connecting spliced ​​displays, the present application provides a video processing method based on splicing technology.

[0054] Reference Figure 1 , a video processing method based on assembling technology, comprising the following steps:

[0055] S101: Obtaining video processing tasks, video data, and feedback information of a connected display device.

[0056] The feedback information of the display device includes the number of display devices, the splicing relationship and the resolution. The splicing relationship is the actual splicing status of the display device. For example, a display device is a spliced ​​display screen, which is composed of 16 small display screens to form a large display screen of 4×4 scale. When these display screens play a video together, the video data to be played at different positions needs to be allocated to each small display screen respectively. In this case, multiple small display screens often need to be connected to the video processing device via a bus, or there is a connection relationship between these small display screens, or each small display screen is directly connected to the video processing device. Different processing solutions are required for different connection situations.

[0057] The video processing task is directly input by the user into the video processing device in the embodiment of the present application. The video processing task is to send one or more video data to one or more designated display devices for playback. The designated display device mentioned above can be a display device or a whole device spliced ​​into multiple display devices. The video processing task includes the number and layout of the required display devices and the index number of the corresponding video data.

[0058] First, it is necessary to obtain the connected display device. When the display device is connected to the video processing device, a verification request is sent to the connected display device to obtain the device information of the connected display device. And according to the device model in the device information, the resolution of the corresponding device model is retrieved.

[0059] There are two ways to obtain the splicing relationship of display devices. The first is to determine whether a set of feedback information contains multiple device information. If there are multiple device information in a set of feedback information, the corresponding display devices have a splicing relationship. At this time, the feedback information may contain the splicing relationship of the display devices. For example, in a set of spliced ​​display devices, multiple display devices are connected to a hub in sequence or multiple display devices are connected in series. In the scenario where multiple display devices are connected in series, the splicing relationship of the display devices can be obtained through a preset identification method. In one implementation scenario,

[0060] In the second case, there is only one display device in a set of feedback information, and there are multiple sets of feedback information. When using a hub and in the second case, it is necessary to obtain additional images returned by the display device, and the display device returns images that require other cameras to aim at the display device to shoot. When obtaining feedback information, a digital identifier is added to the verification instruction. The display that receives the corresponding digital identifier will display the corresponding digital identifier, and then the camera device will collect the data and process it to obtain the splicing relationship between the displays.

[0061] S102: Check whether the feedback information of the display device matches the video processing task.

[0062] After obtaining the feedback information of the display devices, a simulated image of the display devices after splicing is obtained according to the number of display devices and the splicing relationship. The simulated image is a plane model that simulates the actual splicing state of the display devices. The actual splicing state of the display devices, that is, the actual layout of the display devices, can be intuitively analyzed through the simulated image.

[0063] The layout and quantity of display devices also exist in the video processing task. By comparing the actual layout and quantity of display devices, it is determined whether the two are consistent. If they are consistent, the verification passes and the next step of video processing and allocation is carried out.

[0064] S103: Process the video data respectively according to the number, splicing relationship and resolution of the display devices to obtain a processed result video.

[0065] The video data to be played is scaled according to the resolution of the display device, so that the video data can fit the size of the spliced ​​display screen and the video data is displayed clearly. Then, according to the distribution and number of display devices in the simulated image, the video data to be played is cut to obtain multiple sub-video data, where each sub-video data corresponds to a small display.

[0066] The present application provides a video processing system based on assembly technology, which adopts the following technical solutions:

[0069] The verification module 202 is used to verify whether the number and splicing relationship of display devices in the feedback information of the display devices match the number and layout of devices in the video processing task.

[0070] The matching module 203 is used to retrieve the corresponding video data according to the index number after the verification is passed.

[0071] The processing module 204 is used to process the video data according to the number of display devices, the splicing relationship and the resolution to obtain the processed result video, and finally send the result video to the corresponding display device.
