In a specific implementation, after receiving the target left and right eye identifier issued by the previous video processing device 100 from the video processing device 102, the target left and right eye identifier needs to be sent to the next video processing device 104 cascaded with the slave video processing device 102, so that the next video processing device 104 can send left and right eye image information corresponding to the target left and right eye identifier to the LED display screen associated with the next video processing device 104, so that the LED display screen associated with the next video processing device 104 can also display left and right eye images corresponding to the target left and right eye identifier, thereby realizing synchronous display of 3D images of the LED display screen associated with the video processing device 102 and the LED display screen associated with the next video processing device 104.

When receiving the left-right eye switching signal, the main video processing device 100 performs an inversion process on the local left-right eye identifier to obtain the target left-right eye identifier, for example, if the local left-right eye identifier of the main video processing device is the left-right eye identifier, the inversion process is performed, and then the right-eye identifier is obtained as the target left-right eye identifier. On the other hand, the obtained target left and right eye identifiers are transmitted to the next video processing apparatus 102 that is cascaded with the main video processing apparatus 100.
In this embodiment, when the video processing device is a first device of all the video processing devices and receives a left-right eye switching signal issued by an upper computer, the local left-right eye identifier is negated to obtain a target left-right eye identifier, and the target left-right eye identifier is sent to a next video processing device cascaded with the video processing device, so that the next video processing device can synchronize the target left-right eye identifier, and an LED display screen associated with the next video processing device can display a left-right eye picture corresponding to the target left-right eye identifier.

In the specific implementation, the vertical synchronization pulse is issued to the video processing device along with the video source data, a vertical synchronization pulse exists in front of the first video frame, and a vertical synchronization pulse can be considered to exist between every two video frames. When the video processing equipment detects that the next vertical synchronization pulse signal arrives, the target left and right eye identification is sent to the input network port of the network port daughter board in the next video processing equipment through a serdes channel (a serial channel), when the input network port of the network port daughter board in the next video processing equipment receives the target left and right eye identification, the target left and right eye identification is uploaded to the main board of the next video processing equipment through a backboard through an automatic brightness adjusting channel, the main board synchronizes the target left and right eye identification to the local, similarly, when the next vertical synchronization pulse signal arrives, the target left and right eye identification is sent to the next video processing equipment cascaded with the next video processing equipment through the serdes channel, and the like, so that the synchronization of the left and right eye identification of each video processing equipment is realized.

In specific implementation, when the video processing device is a main video processing device, that is, a first video processing device of all the video processing devices, the video processing device can receive video source data from the upper computer, wherein the upper computer can transmit the video source data to the first video processing device through any one of the data interfaces. When the video processing device is a slave video processing device, the video source data may be obtained from a video splicer. All the video processing devices acquire video source data independently and acquire the same signal source data, and all the video processing devices acquire the video source data through a single signal transmission channel.

By the method applied to the video processing equipment provided by the embodiment, the video processing equipment is cascaded, after the first video processing equipment is successfully set, the first video processing equipment sends the setting information to all the video processing equipment in a cascading manner, so that all the video processing equipment is synchronized according to the setting manner of the first video processing equipment, all the cascaded video processing equipment can transmit corresponding left and right eye pictures to the LED display screen associated with each video processing equipment according to the left and right eye marks of the first video processing equipment, the left and right eye pictures displayed by all the video processing equipment are kept synchronized, the adjustment efficiency of the left and right eye pictures of the video processing equipment is greatly improved, and the problem of 3D display in the 3D playing process of the current LED display screen can be solved, thereby ensuring the playing effect of the 3D image.
It can be understood that, in the current 3D display method on the LED display screen, the video processing device converts the video signal into left and right eye pictures with the same frame number, and the left eye picture is viewed by the left eye and the right eye picture is viewed by the right eye in cooperation with corresponding shutter type or polarization type three-dimensional research (the main process is PC terminal-video processing device-LED display screen, and simultaneously video processing device-3D emitter-3D glasses), so that 3D picture display of the LED display screen is realized. However, in the process of converting a video signal into left and right eye pictures with the same number of frames, if the resolution of the left and right eye pictures in the video signal is greater than the layer resolution output to the LED display screen by the video processor (where the layer resolution is equivalent to the resolution required to be displayed by the LED display screen, and therefore the layer resolution is the maximum of the resolution of the LED display screen), the left and right eye pictures cannot be completely displayed in the LED display screen (provided that the left and right eye pictures are not subjected to reduction processing, and partial pixel points are cut down by the reduction processing). The existing method generally cuts out partial picture contents of left and right eye pictures by cutting (how large the left eye picture is cut out, the right eye picture is consistent with the left eye picture, one way is to cut out the left and right eye pictures respectively, and the other way is to cut out the overlapped left and right eye pictures), and the way of cutting out partial pictures will affect the 3D display effect.
Therefore, in an embodiment, the present application further provides another 3D display method, an application scenario of the method is as shown in fig. 5, an upper computer 500 is in communication connection with a video processing device 502, the video processing device 502 and the video processing device 504 are in cascade connection, and the video processing device 502 and the video processing device 504 respectively carry a left half picture and a right half picture of the same LED box 506. The upper computer 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices.
As shown in fig. 6, the method is exemplified by being applied to a video processing apparatus 502, and the method includes the following steps:
step S602, when a left and right eye switching signal sent by the upper computer is received, negation processing is carried out on the local left and right eye identification of the video processing equipment to obtain the target left and right eye identification.
And step S604, sending the left and right eye picture information corresponding to the target left and right eye marks to the LED box body.
Step S606, the target left and right eye identification is sent to the next video processing device cascaded with the video processing device, so that the next video processing device sends left and right eye picture information corresponding to the target left and right eye identification to the LED box; the video processing equipment and the next video processing equipment are respectively used for processing the left half picture information and the right half picture information of the video frame displayed by the LED box body; and the LED box body is used for simultaneously displaying a left eye picture and a right eye picture corresponding to the left half picture of the video frame and a left eye picture and a right eye picture corresponding to the right half picture of the video frame according to the target left eye and right eye identification.
In specific implementation, the video source data can be divided into left half video source data and right half video source data in advance in the upper computer, the video processing device 502 and the video processing device 504 respectively process the left half video source data and the right half video source data, and the LED box body 506 can be loaded by the two video processing devices. The video processing device 502 is configured to convert left half video source data into a left-eye picture 1 and a right-eye picture 1, the next video processing device 504 is configured to convert right half video source data into a left-eye picture 2 and a right-eye picture 2, when 3D picture display is performed on the LED box 506, the video processing device 502 sends information of the left-eye picture 1 to the LED box 506, so that the left half display screen of the LED box 506 displays the left-eye picture 1, and the video processing device 504 sends information of the left-eye picture 2 to the LED box 506, so that the right half display screen of the LED box 506 displays the left-eye picture 2, thereby realizing that the LED box displays the left-eye picture of the video source data.

Therefore, in this embodiment, the upper computer may issue a left-right eye switching signal to the video processing device 502, and when receiving the left-right eye switching signal issued by the upper computer, the video processing device 502 performs an inversion process on the local left-right eye identifier to obtain a target left-right eye identifier, and sends left-right eye image information corresponding to the target left-right eye identifier to the LED box 506, so that the left half display screen of the LED box 506 displays the left-eye image 1. On the other hand, the video processing device 502 sends the obtained target left and right eye identifier to the next video processing device 504, so that the next video processing device 504 sends left and right eye picture information corresponding to the target left and right eye identifier to the LED box 506, and the right half display screen of the LED box 506 displays the left eye picture 2 first. Therefore, the playing mode of the picture on the LED box body is to be the alternate playing of the left-eye picture and the right-eye picture, namely the pictures are played in sequence: left-eye picture 1 and left-eye picture 2 → right-eye picture 1 and right-eye picture 2 → left-eye picture 1 'and left-eye picture 2' → right-eye picture 1 'and right-eye picture 2'.

For example, the resolution is 10 × 20 for the top-bottom division, and the resolution is 20 × 10 for the left-right division.
In another embodiment, the vertical division or the horizontal division may also be used as a control parameter, and the upper computer issues the control parameter to the video processing device along with the control parameter, and the video processing device performs the equal division of the video frames in the video source data. Specifically, when the upper computer issues the video source data to the video processing device through the data transmission interface, the control parameter may be issued to the video processing device through the USB interface along with the video source data, so that the video processing device performs equal division of the video frame according to the control parameter.
