Problems solved by technology

[0003] Although RS-232 communication interface control splicing brings great convenience and user experience to users, it requires users and control devices to realize control functions within a limited distance, and the realization (more than 1 km) of remote control needs to be added. Repeaters are used to achieve remote control capabilities, which brings great challenges to engineering wiring, high implementation costs, and signal quality cannot be fully guaranteed
In addition, the central processing unit must be fixed in a specific studio, which cannot meet the needs of flexible office in the future

Embodiment 1

[0053] see figure 2 , embodiment 1: the remote control method of video processing equipment of the present invention, comprises:

[0054] Step 1: The central processing unit sends a confirmation packet to the remote video processing device, whether the device exists in the network, for example, the central processing unit sends a confirmation packet to the remote 4th video processing device;

[0055] Step 2: The confirmation data packet downloaded by the central processing unit is passed down in a point-to-point cascading manner, that is, the central processing unit sends the confirmation data packet to the remote first video processing device, and the first video processing device will confirm the data The packet is compared with the identification of the device. If the comparison result is inconsistent, the first video processing device will confirm that the data packet will continue to be transmitted down to the remote second video processing device. Similarly, the second...

Embodiment 2

[0062] see image 3 , embodiment 2: the remote control method of video processing equipment of the present invention, comprises:

[0063] Step 1: The central processing unit sends a confirmation packet to the remote video processing device, whether the device exists in the network, for example, the central processing unit sends a confirmation packet to the remote fourth video processing device;

[0064] Step 2: The confirmation data packet downloaded by the central processing unit is transmitted downward in the form of broadcasting, that is, the central processing unit sends the confirmation data packet to the remote first video processing device, the second video processing device, and the third remote video processing device at the same time. The video processing device, the fourth video processing device, the fourth video processing device will confirm that the data packet is consistent with the identification of the device. At this point, the fourth video processing device...

Abstract

The invention relates to the technical field of video, and discloses a remote control method and a remote video processing device for a video processing device. The remote video processing device comprises a central processing unit, S remote video processing devices and a large screen, wherein the S remote video processing device comprise n paths of video input ends and m paths of video output ends, the central processing unit is in signal communication with the S remote video processing devices through a 3G wireless receiving and transmitting antenna and a 3G network, control modules are respectively embedded in the central processing unit and the S remote video processing devices, and the control modules are used for signal processing and conversion and mode adjustment between the central processing unit and the S remote video processing devices. The remote control method and the remote video processing device for the video processing device are low in cost on establishment, and can guarantee signal quality; and control devices are convenient to mount and set.

Description

technical field [0001] The invention relates to the field of video technology, in particular to a remote control method for video processing equipment. The invention also relates to a remote video processing device. Background technique [0002] The video splicing system currently on the market can realize functions such as splitting, split-screen display, window opening, and window roaming. Due to the use of hardware splicing, the image processing is completely real-time dynamic display, image superimposition, simple installation and operation, and fast startup time. Using RS-232 control, the window is fixed to a screen size, can be enlarged, reduced or moved, and can support multi-screen splicing. The whole system runs in a closed mode without being affected by any virus, no need to install an operating system, and it is plug-and-play. Each RGB channel is calculated independently, and the signal processing is more detailed; RGB and video images can be superimposed on eac...
