The quality of digital interaction methods, and in the process of remote interaction, it is often difficult to ensure that the peer video signal can definitely match the display requirements of the local display device. If the display is directly output, the quality of the output display may be affected due to poor adaptability, for example The video format does not match, the image size does not match the screen size, the resolution or refresh rate does not match, etc. Therefore, the video signal uploaded to the cloud server by the opposite end is decoded, image processed and encoded through the ultra-high definition video signal processing equipment. , which can make the video signal better match the actual needs of the local display device.

The image processing module 12 can be connected to the ultra-high-definition video decoding module 11, receive each of the decoded signals obtained after decoding by the ultra-high-definition video decoding module 11, and decode each of the decoded signals according to a preset image processing method.

Or superimpose and combine to form a whole image, adjust the size of the image or adjust the saturation, brightness and other image parameters of the image, etc. The image processing method can be the method set by default in the ultra-high-definition video signal processing device, or It may be an image processing method determined based on user operation obtained through application software corresponding to the ultra-high definition video signal processing device.

In this embodiment, specifically, the image processing includes image cutting processing, and the image processing module includes an image cutting unit. The image cutting unit performs image cutting on each of the decoded signals based on preset image cutting rules. Processing to obtain at least one signal to be encoded, wherein the preset image cutting rule is a cutting method for cutting the image, which can be the method set by default in the ultra-high definition video signal processing device, or can be through the The application software corresponding to the ultra-high-definition video signal processing equipment obtains the image processing method determined based on user operations.

In an implementable manner, the step of performing image cutting processing on each of the decoded signals based on a preset image cutting rule includes: obtaining the number of the display devices corresponding to each of the decoded signals, and determining each Whether the number of display devices corresponding to one decoded signal is more than one. If it is determined that in each of the decoded signals, there is an image to be processed corresponding to more than one display device, through the application software corresponding to the ultra-high-definition video signal processing device. The user is prompted to determine whether to perform image cutting processing on the image to be processed by inputting a control instruction. If it is determined to perform image cutting processing on the image to be processed based on the user operation information, the user is prompted to input a control instruction through the application software. (For example, through remote control input, selection or input in the display interface, etc.), determine the cutting position corresponding to the image to be processed and the target display device for output display corresponding to each partial image after cutting, according to the At the cutting position, the image to be processed is cut into at least one partial image, and each partial image carries the identification code of its corresponding target display device, so that each of the target display devices can output and display its corresponding partial image. Accurate cutting and directional display of images, wherein the partial image is a part of the image to be processed obtained after the image to be processed is segmented according to the cutting position, and all partial images can be combined into a complete image to be processed.

If it is determined based on the user operation information that the image to be processed is not to be image cut, the complete image to be processed is output and displayed through each of the display devices.

In an implementable manner, referring to Figure 2, the target display device corresponding to the image to be processed includes display A, display B, display C and display D. Based on the user operation information, it is determined to cut the image to be processed in a field shape, and cut The final partial image A corresponds to display A, partial image B corresponds to display B, partial image C corresponds to display C, and partial image D corresponds to display D. We can obtain partial image A, partial image B, partial image C and partial image Image D, and display partial image A through display A, display partial image B through display B, display partial image C through display C, and display partial image D through display D.

In this embodiment, through image cutting, multiple monitors can output and display parts of a complete video at the same time, thereby realizing the output of the complete video, which can increase the video display area while ensuring the video display quality. Clarity.

In this embodiment, specifically, the image processing includes image superposition processing, and the image processing module includes an image superposition unit.

If it is determined that the number of decoded signals corresponding to each of the display devices is , if there is a first target display device with more than one corresponding decoded signal, it means that the first target display device needs to output and display more than one decoded signal, and the user is prompted to use the corresponding application of the ultra-high-definition video signal processing device. The software inputs control instructions (for example, through remote control input, selection or input in the display interface, etc.) to determine the superimposed display mode of the images to be processed corresponding to each of the decoded signals. According to the superimposed display mode determined by the user, all The image to be processed corresponding to the decoded signal corresponding to the first target display device is subjected to image overlay processing, wherein the overlay display method includes combination display or switching display, and the image overlay processing includes image combination processing and image switching processing, etc., The combination is displayed by superimposing or splicing the images to be processed in the same display area, and synthesizing the superimposed or spliced images to be processed into an image to be encoded. In the image to be encoded, each of the images to be processed is The images to be processed are output and displayed in their respective display areas. The signal collection, transmission, processing and output corresponding to each of the images to be processed are independent of each other and do not interfere with each other. For example, when one of the images to be processed is due to signal or other reasons, Causes an interruption, and other uninterrupted images to be processed can still continue to be output and displayed; the switching display is to set one of the images to be processed as the image to be encoded, and when the video switching instruction is received, the image to be encoded is switched to the switching instruction. The corresponding picture of the image to be processed.

In an implementable manner, refer to Figure 3, which is a schematic diagram of a scene for performing image combination processing on the images to be processed. Image A, image B, and image C all correspond to the same target.

Among them, the layer position of the image A to be processed is in the image to be processed. The layer position of B is the upper layer, so the part of the image B that overlaps with the image A will be blocked by the image A. In addition, if the image A, the image B, or the image C are If any signal is interrupted, it cannot be output and displayed. The images to be processed that are not interrupted by other signals will continue to be output and displayed.

In this embodiment, through image overlay processing, various actual situations in digital interaction processes such as digital teaching, video conferencing, and remote diagnosis can be flexibly dealt with. For example, in the digital teaching process, video images can be displayed simultaneously during the lecture. Lecture PPT (PowerPoint, presentation software) and the teacher's lecture screen.
