Technical Field

The utility model relates to a visual technical field of data especially relates to a display control system and display system.

Background

With the rapid development of wireless communication technology, more and more application scenarios need to be supported by big data. Data visualization is an important display mode for big data processing, and the screen wall is the most intuitive, common and valuable display means. At present, screen walls with two structures are provided, one is formed by a television array, and the other is formed by a Light Emitting Diode (LED) array. Compared with the prior art, the screen wall visual display scheme has the advantages that the cost performance is high, the screen splicing gap is smaller than 7mm, the screen wall visual display scheme belongs to the acceptable range of users, and the like, and the screen wall visual display scheme is the mainstream. The solution is completed by a television display screen and a splicing control system, wherein the splicing control system is responsible for receiving video signals, cutting the signals and respectively sending the signals to input interfaces of the television display screens through signal lines for picture display.

However, the display control system using the tv array as the screen wall still faces many problems, for example, the interface configuration is not flexible, that is, how many output interfaces the mosaic control system has to have for how many tv display screens, and when there are many display screens, more output interfaces are needed, which results in an excessively high input cost of the mosaic control system. In addition, a longer signal line is also required, and an excessive line cost is required to ensure that the signal line has no quality loss. Moreover, the splicing control system has large volume, large noise and large heat generation, and is not suitable for being arranged in the environment of indoor screen walls and meeting place screen walls. As can be seen, conventional display control systems based on video signals are becoming increasingly unsuitable for use in the various current application scenarios. A distributed pure digital display control system based on a data network mode becomes an important direction for the visualization development of data in the future.

However, the current display control system based on the network IP method only transmits data signals through the network cable, which essentially only reduces the cost of transmitting wires, and the digital video stream transmitted in the network occupies a large amount of network bandwidth when the number of spliced screens is large (for example, more than 30 blocks), and even requires the construction of a gigabit network including a gigabit network cable and a gigabit switch, which still results in high wire cost. The input cost is not lower than that of the traditional display control system based on the video signal.

With the rapid development of wireless communication technology, more and more application scenarios need to be supported by big data. The data visualization is an important display mode for big data processing, and the screen wall is the most intuitive display means, the most common application means and the most reference value. The screen wall structure has two screen walls, namely a television array screen wall and an LED array screen wall, and the former screen wall is a mainstream screen wall structure due to the factors that the cost performance is high, the splicing gap of the screen is less than 7mm, and the like, and the screen wall structure belongs to the acceptable range of users. The whole display control system consists of a television display screen and an assembly control system, wherein the assembly control system is responsible for receiving video signals, cutting the signals and respectively sending the signals to input interfaces of the television display screens through signal lines to display pictures. However, such a display control system still faces many problems, for example, the interface configuration is not flexible, and as the display screens are more tiled, the tiled control system has to provide more corresponding output interfaces, which causes the cost to be too high. Therefore, more signal lines need to be provided, and in order to ensure the quality of signals, it is also necessary to purchase good-quality signal lines at higher cost. Moreover, the larger the volume of the mosaic control system is, the larger the noise and heat generation are, and the mosaic control system is not suitable for being deployed in application environments such as indoor and meeting places. It follows that display control systems based on conventional video signals are increasingly unsuitable for the various application scenarios at present. Therefore, a distributed digital display control system based on a data network mode becomes an important direction for the development of data visualization in the future.

However, the current display control system based on the network IP method only transmits data signals through the network cable, which essentially only reduces the cost of transmitting wires, and the digital video stream transmitted in the network occupies a large amount of network bandwidth when the number of spliced screens is large (for example, more than 30 blocks), even requires the construction of a gigabit network including a gigabit network cable and a gigabit switch, which causes the cost of wires to be still high, and the input cost to be not lower than that of the traditional display control system based on video signals. In addition, in practical situations, especially for the display of static or quasi-static data pictures, and the display of periodically changing pictures, the investment cost is an unnecessary extra investment.

The display control system includes a source screen control device, a front control device, and a plurality of node control devices. The source picture control device is in wireless communication connection with the front control device, and the front control device is in communication connection with each node control device respectively. And the source picture control equipment responds to the request instruction to send the target picture to the preposed control equipment, and the preposed control equipment controls the node control equipment according to the number and the distribution mode of the node control equipment so that the node control equipment outputs the target picture to the sub-screen.

It is to be understood that, before the target screen is transmitted, the source screen control apparatus 100 performs pairing authentication with the front control apparatus 200, for example, the front control apparatus 200 actively initiates a verification instruction, and the source screen control apparatus 100 passively receives verification to realize pairing and establish connection.

The terminal device is provided with an acquisition module for acquiring screen matrix data, wherein the screen matrix data comprises a target picture to be displayed by the display system. For example, Publisher software is installed in the terminal device, so that the terminal device can run the software to acquire screen matrix data, thereby obtaining a target picture.

For a possible implementation manner, the first terminal device obtains the target picture in a manner that the obtaining module reads the screen matrix data, and performs targeted capture, for example, a screen capture manner, on the sample picture presented by the screen matrix data, so as to obtain the target picture, which is in a picture format. It should be understood that, when the target frame is a periodic cyclic frame, the target frame includes a repeated picture, and the cyclic frame is a frame of the repeated picture. At this time, the obtaining module is further configured to add timestamp information to the repeated pictures, where the timestamp information is used to represent display timings of the pictures in all the pictures. It is understood that, when the loop picture is displayed, the source picture control apparatus 100 transmits only the time stamp information corresponding to the picture of the loop picture to the front control apparatus 200 in response to the request instruction without transmitting the target picture to save bandwidth resources.

In a possible design, as shown in fig. 3, fig. 3 is a schematic structural diagram of a front control device provided in an embodiment of the present invention, and the front control device 200 provided in an embodiment of the present invention includes a second terminal device, for example, a server shown in fig. 1.

It is to be understood that, regardless of whether the loop picture is included in the target picture, when the source picture control apparatus 100 transmits the target picture to the front control apparatus 200 after the display control system is turned on, all information of the target picture, including the time stamp information, is transmitted to the front control apparatus 200.

The picture processing module 2012 is used to cut and compare the target picture to determine an updated sprite.

Upon receiving the target picture, the picture processing module 2012 cuts the target picture to determine an updated sprite. As described above, the front control device 200 controls the node control devices 300 according to the number and the distribution manner of the node control devices 300, and the node control devices 300 have a one-to-one correspondence relationship with the sub-screens included in the screen 400, so that the screen processing module 2012 can cut the target screen according to the number and the distribution manner of the sub-screens to obtain the sub-screens, compare the sub-screens with the display screens of the previous frame and the current frame on the sub-screens, and if the sub-screens are changed, determine that the sub-screens are updated sub-screens.

Optionally, the picture processing module 2012 is further configured to perform picture quality adjustment on the target picture according to the resolutions of all the sub-screens, so as to improve the picture display quality. It will be appreciated that all sub-screens have the same resolution.

The timing adding module 2013 is used for adding the same time stamp to the updated sub-picture. That is, for all the updated sprites included in the same display screen, the timing adding module 2013 adds the same timing to all the updated sprites to display the updated sprites on the sub-screen according to the same timing.

The node management module 2014 is used for outputting the updated sub-picture and the time sequence to each node control device.

Specifically, the node management module 2014 correspondingly outputs the updated sprite and the time sequence to each node control device according to the IP address information of each node control device.

It can be understood that, when the updated sprite is a duplicate picture in the target picture, the node management module 2014 outputs only the timestamp information added by the acquisition module in the source picture control device 100 for the corresponding picture to the corresponding node control device without repeatedly transmitting the updated sprite, thereby saving bandwidth.

The embodiment of the utility model provides a display control system, leading controlgear include second terminal equipment, carry on processing module in this terminal equipment, and processing module includes that picture buffering module, picture processing module, chronogenesis add module and node management module. And the picture buffer module performs picture restoration on the timestamp information and the picture of the corresponding circulating picture to realize target picture buffering. The image processing module cuts and compares the target image to determine an updated sub-image, the time sequence adding module adds the same time sequence to all the updated sub-images, and the node management module is used for outputting the updated sub-image and the time sequence to each node control device. Therefore, aiming at the target picture, only the updated sub-picture needs to be monitored, and the updated sub-picture is output, so that the occupation of transmission bandwidth is effectively reduced, network resources are saved, and the transmission efficiency is improved.

In one possible design, each node control device of the node control devices 300 includes a third terminal device, where the third terminal device includes a preset signal output interface, and the preset signal output interface includes a signal output interface such as a multimedia interface or a digital video interface.

The third terminal device includes a preset signal output Interface, where the preset signal output Interface includes a Multimedia Interface or a Digital video Interface, such as a High Definition Multimedia Interface (HDMI), a Digital Video Interface (DVI), and other data signal output interfaces.

In one possible design, each node control device outputs the updated sub-picture to the corresponding sub-screen through the multimedia interface. Or

And each node control device outputs the updated sub-picture to the corresponding sub-screen through the digital video interface.

When the third terminal device includes a multimedia interface, each node control device 301 outputs an updated sub-picture to the corresponding sub-screen through the multimedia interface.

When the third terminal device includes a digital video interface, each node control device 301 outputs an updated sub-picture to the corresponding sub-screen through the digital video interface.

The setting of the preset signal output interface, i.e. the multimedia interface or the digital video interface, included in the third terminal device may be determined according to the target picture in the actual working condition, which is not limited in this embodiment.

It is understood that each node control device includes a third terminal device capable of restoring the received repeated updated sub-screen according to the timestamp information, and then outputting the restored updated sub-screen to the corresponding sub-screen, so that the sub-screens are displayed according to the same timing sequence.
