     First Embodiment 
     Referring to  FIG.  1   , a first embodiment of the embodiments of the disclosure provides a data processing method. As shown in  FIG.  1   , the method for processing data provided in the first embodiment of the embodiments of the disclosure includes, for example, steps S 11  to S 15 . 
     Step S 11 : input image data is received; 
     step S 12 : the image data in a memory is stored; 
     step S 13 : target image data from the memory according to loaded area information of at least one output portal is read, wherein the output portal is electrically connected with a display screen, and the loaded area information of the output portal characterizes a target display area of the display screen; 
     step S 14 : the target image data compressed to reduce the data volume of the target image data to meet a output bandwidth of the output portal to obtain compressed image data characterized by a plurality of image data packets; 
     step S 15 : the compressed image data through the output portal is output. 
     Specifically, the image data mentioned in step S 11  is, for example, image data in DVI format or image data in HDMI format. The memory mentioned in step S 12  is for example a dynamic random access memory. For example, DDR memory is used. 
     The loaded area information mentioned in step S 13  characterizes the target display area of the display screen, for example, the loaded area information includes the starting coordinates of the image to be displayed of the target display area loaded by the output portal and the width and height of the image. A resolution size of the mentioned target display area is e.g. 1080P or greater. The mentioned display screens are, for example, spliced display screens formed, for example, by splicing a plurality of display units, wherein each display unit includes a plurality of display modules, and a single display module includes a plurality of LED light points. The display screen is for example an LED display screen. The target display area of the display screen is driven and controlled by a plurality of cascaded mudure controllers, for example, and a first-stage mudure controller in the cascaded mudure controllers is connected with the mentioned output portal through a cable. 
     The compression process mentioned in step S 14  for example includes changing the encoding format of each pixel data in the target image data. The compression process may support low-latency visually lossless compression of image data, for example using an image compression algorithm such as JPEG2000. For example, when the output bandwidth of the output portal is 1 Gbps, the target image data is compressed and the amount of data transmitted by the target image data is reduced to below 1024 Mbit. Of course, the embodiments of the embodiments of the disclosure do not limit the output bandwidth of the output portal, and the compression process is similar when the output bandwidth is 5 Gbps. 
     Further, reference to an image data packet includes, for example, an identification code of a corresponding mudure controller among a plurality of cascaded mudure controllers. The identification code in the image data packet can ensure that each mudure controller under the output portal accurately identifies the image data to be loaded by the mudure controller so as to ensure that each mudure controller can accurately obtain the part of the image data controlled by the mudure controller. And after the mudure controller receives the image data packet, an identification code of the mudure controller is analyzed, and compared with a local identification code, and if the two identification codes are the same, the transmitted image data packet is determined to be the image data to be loaded by the mudure controller. 
     For a better understanding of the present embodiment, a detailed implementation of the method for processing data provided by the present embodiment is described below with reference to  FIG.  2   . The method for processing data provided by the embodiment is implemented in a system controller, wherein  FIG.  2    is a data flow diagram of the system controller implementing the method of the embodiment. 
     Specifically, in the system controller, the video interface parses image data representing receipt of input and decodes the image data. The input image data is in a DVI format or an HDMI format, for example. Writing to memory indicates that the image data is cached in the DDR memory, and then the read memory indicates that the target image data is read out from the image data stored in the DDR memory according to the loaded area information corresponding to the target display area. The mentioned loaded area information includes the coordinates of the image to be displayed and the image width and height of the target display area under the portal. In consideration of the irregularity of the configuration of the special-shaped display screen, in order to reduce bandwidth waste, reading of image data and bit interception can be carried out in display units, i.e. a load area of each mudure controller, or reading of image data can be carried out in units of load areas of a single portal, and the embodiment is not limited to reading units of image data. Compression means that the target image data read out is compressed by a compression algorithm to reduce the amount of data transmitted. In addition, in order to satisfy the load of the display screen input by the 10-bit video source of 1080P, the transmission bandwidth of the 10-bit input source of the 1080P display screen can be calculated as 1920*1080*60*10*3=3.74 Gpbs, wherein 1920*1080 represents the resolution of the display screen, 60 represents the frame rate, 10 represents the bit depth of the input video source, and 3 represents the RGB three primary colors. When the network transmission bandwidth is 1 Gbps, the compression algorithm is needed to support four times lossless compression of image data. Of course when the bit depth of the input video source is higher, e.g. 12 bits, the corresponding compression algorithm may support a higher compression ratio while ensuring visual lossless. The compression process mentioned is, for example, to change the encoding format of each pixel data in the target image data to reduce the amount of transmission data of the target image data to meet the output bandwidth of the portal. The compressed image data obtained by the compression processing is characterized by a plurality of image data packets. The portal output indicates that the compressed image data is output to the mudure controller through the portal. 
     Furthermore, before the compressed image data is output, in order to ensure that the mudure controller under the portal can recognize the image data loaded by the mudure controller, the identification code of the corresponding mudure controller can be added into the image data packet, and at the moment, the corresponding image data packet is obtained by compressing the loaded area of each mudure controller as a unit. 
     In summary, according to the method for processing data provided by the embodiment, the target image data is compressed to reduce the data volume of the target image data to meet the output bandwidth of the output portal and then is output through the output portal, so that the limitation of transmission bandwidth of a single network line is eliminated, the loading requirement of a 1080P display screen loaded by the single network line is met, and a situation where a large-resolution display screen is loaded by too many network lines in the related art is avoided, the use of wires is reduced, and the cost is saved; the method has the advantages that tedious steps of determining various connection line relationships during screen configuration are avoided, workload is reduced for the working staff, efficiency is improved, cross connection of a plurality of wires is avoided, stability of a system is improved, aesthetic feeling is improved, which is advantageous for the popularization and use of a display screen.

The compression module  24  is used for loading out compression processing on the target image data to reduce the data volume of the target image data to meet a output bandwidth of the output portal so as to obtain compressed image data characterized by a plurality of image data packets. The output module  25  is used for outputting the compressed image data through the output portal.

     Fourth Embodiment 
     Referring to  FIG.  6   , a fourth embodiment of the embodiments of the disclosure provides a method for data processing. As shown in  FIG.  6   , the method for processing data includes, for example, steps S 41  to S 45 . 
     Step S 41 : an image data packet via an input portal to obtain compressed image data is received, wherein the input portal is a portal on a mudure controller electrically connected with a target display area of a display screen; 
     step S 42 : the compressed image data to obtain decompressed image data is decompressed; 
     step S 43 : the decompressed image data in a memory is stored; 
     step S 44 : decompressed image data corresponding to the mudure controller from the memory is read; 
     step S 45 : driving and controlling the target display area of the display screen to carry out image display according to the read decompressed image data corresponding to the mudure controller. 
     Specifically, in step S 41 , the mentioned image data packet includes compressed image data, or includes compressed image data and a mudure controller identification code. The display screen is for example a spliced display screen, and the display screen is formed by splicing a plurality of display units, wherein each display unit includes a plurality of display modules, and each display module includes a plurality of LED light points. The display screen is for example an LED display screen. 
     The decompression process mentioned in step S 42  restores, for example, the encoding format of each pixel data in the target image data to the encoding format before the compression process. The memory mentioned in step S 43  is for example a dynamic random access memory, for example a DDR memory. A resolution size of the target display area mentioned in step S 45  is, for example, 1080P or greater. The target display area of the display screen is driven and controlled, for example, by a plurality of cascaded mudure controllers. Step S 45  for example includes: carrying out luminance correction and color gamut adjustment processing on the read decompressed image data corresponding to the mudure controller to obtain corrected image data; and driving and controlling the target display area of the display screen to display the image according to the corrected image data. 
     Further, when the mudure controller identification code is included in the image data packet, as shown in  FIG.  7   , step S 411  and step S 412  are further included before step S 42 , for example. 
     Step S 411 : an mudure controller identification code contained in the image data packet is parsed; 
     Step S 412 : and judging whether the mudure controller identification code is matched with the local identification code or not, to be used for determining whether to carry out decompression processing. 
     The image data packet at this time is compressed, for example, by taking the load area of each mudure controller as a unit. When the identification code of the controller of the module is judged to be matched with the local identification code, that is, the identification code of the controller is the same as the local identification code, decompression processing is carried out. If the mudure controller identification code and the local identification code are judged not to be matched, that is, the controller identification code and the local identification code are not the same, decompression processing is not carried out, and the received image data packet is forwarded to a next-stage mudure controller cascaded with the mudure controller. When the identification code of the mudure controller is judged to be matched with the local identification code, the decompressed image data obtained by decompressing the compressed image data is the decompressed image data corresponding to the mudure controller. 
     Furthermore, when no mudure controller identification code is included in the image data packet, the image data packet is compressed by taking a portal as a unit, and the decompressed image data obtained by decompressing the compressed image data is decompressed image data corresponding to a plurality of mudure controllers, not only the decompressed image data corresponding to the mudure controllers. Thus, step S 44  includes, for example: intercepting the decompressed image data to obtain the decompressed image data corresponding to the mudure controller. The operation of intercepting the decompressed image data is, for example, intercepting the decompressed image data according to the initial coordinate, width and height of the load area of the mudure controller. Before the step S 42 , further included is: forwarding the image data packet to a next-stage mudure controller cascaded with the mudure controller. After receiving the image data packet, the next-stage mudure controller carries out decompression processing, image data interception and the like. 
     It should be noted that the method for processing data provided by the present embodiment is considered from the point of view of the mudure controller, and the method for processing data provided by the first embodiment is considered from the point of view of the system controller. 
     For a better understanding of the present embodiment, a detailed implementation of the method for processing data provided by the present embodiment is described below with reference to  FIG.  8   . The method for processing data provided by the embodiment is implemented in a mudure controller, wherein  FIG.  8    is a data flow diagram of the mudure controller implementing the method of the embodiment. 
     In the mudure controller, the portal analytic representation carries out unpacking processing on the transmitted image data packet to obtain compressed image data. Decompression means buffering and decompressing the compressed image data to obtain decompressed image data. Writing to memory means saving decompressed image data to a DDR memory. The read memory indicates that the decompressed image data of the corresponding mudure controller is read from the DDR memory, and the decompressed image data of the corresponding mudure controller mentioned here is, for example, a part of the decompressed image data stored in the DDR memory, i.e. the decompressed image data of the corresponding mudure controller is obtained by intercepting the decompressed image data. The correction means carrying out luminance correction and color gamut adjustment processing on the decompressed image data of the corresponding mudure controller and then storing the decompressed image data in the DDR memory again. The IC driver means that the decompressed image data of the corresponding mudure controller is read from the DDR memory according to the chip time sequence requirement to drive and control the target display area of the display screen for image display. In addition, in the process, the mudure controller unconditionally forwards the received image data packet to a next-stage mudure controller cascaded with the mudure controller. 
     On the other hand, when the transmitted image data packet received by the mudure controller includes the mudure controller identification code, the portal parsing also indicates that the image data packet is unpacked to obtain the mudure controller identification code, at the moment, whether the mudure controller identification code and the local identification code are matched or not is judged firstly, and if the mudure controller identification code and the local identification code are not the same, the transmitted image data packet does not belong to the mudure controller, decompression processing cannot be carried out. The transmitted image data packet needs to be transmitted to the plurality of cascaded mudure controllers. If the mudure controller identification code and the local identification code are the same, decompression processing can be carried out. Decompression means buffering and decompressing the compressed image data to obtain decompressed image data. Writing to memory means saving decompressed image data to a DDR memory. Reading the memory means the decompressed image data of the corresponding mudure controller is read from the DDR memory, wherein the decompressed image data of the corresponding mudure controller is all the decompressed image data stored in the DDR memory. The correction means that the decompressed image data is subjected to luminance correction and color gamut adjustment processing and then stored in the DDR memory again. The IC driver means that the decompressed image data is read from the DDR memory according to chip timing requirements to drive and control a target display area of the display screen for image display. 
     In summary, according to the method for processing data provided by the embodiment of the disclosure, the compressed image data is decompressed and stored in the memory, and the decompressed image data of the corresponding mudure controller is read to drive and control the target display area to carry out image display, so that the limitation of transmission bandwidth of a single network line is eliminated, the loading requirement of a 1080P display screen loaded by the single network line is met, and a situation where a large-resolution display screen is loaded by too many network lines in the related art is avoided, the use of wires is reduced, and the cost is saved; the method has the advantages that tedious steps of determining various connection line relationships during screen configuration are avoided, workload is reduced for the working staff, efficiency is improved, cross connection of a plurality of wires is avoided, stability of a system is improved, aesthetic feeling is improved, which is advantageous for the popularization and use of a display screen.

As shown in  FIG.  11   , the system for processing data  70  includes, for example: a system controller  71  and at least one mudure controller  72 . The system controller  71  includes at least one output portal  711 .

     For a better understanding of the present embodiment, the detailed operation of the system for processing data of the present embodiment will now be described with reference to  FIG.  12   .  FIG.  12    is a data flow diagram of the system for processing data of the present embodiment. 
     Specifically, in the system controller, the video interface parses image data representing receipt of input and decodes the image data. The input image data is in a DVI format or an HDMI format, for example. Writing to memory indicates that the image data is cached in the DDR memory, and then the read memory indicates that the target image data is read out from the image data stored in the DDR memory according to the loaded area information corresponding to the target display area. The mentioned loaded area information includes the coordinates of the image to be displayed and the image width and height of the target display area under the portal. Here, in consideration of the irregularity of the configuration of the special-shaped display screen, in order to reduce the bandwidth waste, the reading of the image data and the bit interception can be carried out in display units, or the reading of the image data can be carried out in units of the loaded area of the single portal, and this embodiment does not limit the units for reading the image data. Compression means that the target image data read out is compressed by a compression algorithm to reduce the amount of data transmitted. In addition, in order to satisfy the load of the display screen input by the 10-bit video source of 1080P, the transmission bandwidth of the 10-bit input source of the 1080P display screen can be calculated as 1920*1080*60*10*3=3.74 Gpbs, wherein 1920*1080 represents the resolution of the display screen, 60 represents the frame rate, 10 represents the bit depth of the input video source, and 3 represents the RGB three primary colors. When the network transmission bandwidth is 1 Gbps, the compression algorithm is needed to support four times lossless compression of image data. Of course when the bit depth of the input video source is higher, e.g. 12 bits, the corresponding compression algorithm may support a higher compression ratio while ensuring visual lossless. The compression process mentioned is, for example, to change the encoding format of each pixel data in the target image data to reduce the amount of transmission data of the target image data to meet the output bandwidth of the portal. The compressed image data obtained by the compression processing is characterized by a plurality of image data packets. The portal output indicates that the compressed image data is output to the mudure controller through the portal. 
     Furthermore, before compressed image data are output, in order to ensure that the mudure controller under the portal can recognize the image data loaded by the mudure controller, an identification code corresponding to the mudure controller can be added into the image data packet. 
     In the mudure controller, when the transmitted image data packet does not include the mudure controller identification code, the image data packet is compressed by taking a portal as a unit, for example. And the portal parsing indicates that the transmitted image data packet is unpacked to obtain compressed image data. Decompression means buffering and decompressing the compressed image data to obtain decompressed image data. Writing to memory means saving decompressed image data to a DDR memory. The read memory indicates that the decompressed image data of the corresponding mudure controller is read from the DDR memory, and the decompressed image data of the corresponding mudure controller mentioned here is, for example, a part of the decompressed image data stored in the DDR memory, i.e. the decompressed image data of the corresponding mudure controller is obtained by intercepting the decompressed image data. The correction means carrying out luminance correction and color gamut adjustment processing on the decompressed image data of the corresponding mudure controller and then storing the decompressed image data in the DDR memory again. The IC driver means that the decompressed image data of the corresponding mudure controller is read from the DDR memory according to the chip time sequence requirement to drive and control the target display area of the display screen for image display. In addition, the mudure controller also forwards the image data packet to a next-stage mudure controller cascaded with the mudure controller. 
     On the other hand, when the transmitted image data packet received by the mudure controller includes the mudure controller identification code, the image data packet at the moment is obtained by compressing, for example, a load area of each mudure controller as a unit. The portal parsing also indicates that the image data packet is unpacked to obtain the mudure controller identification code, at the moment, the mudure controller judges whether the mudure controller identification code is matched with the local identification code or not, if the mudure controller identification code is not the same as the local identification code, the transmitted image data packet does not belong to the mudure controller, decompression processing cannot be carried out, and the transmitted image data packet needs to be transmitted to the next cascaded mudure controller. If the mudure controller identification code and the local identification code are the same, decompression processing can be carried out. Decompression means buffering and decompressing the compressed image data to obtain decompressed image data. Writing to memory means saving decompressed image data to a DDR memory. Reading the memory means reading the decompressed image data of the corresponding mudure controller from the DDR memory, for example, all the decompressed image data stored in the DDR memory. The correction means that the decompressed image data is subjected to luminance and chrominance correction processing and then stored in the DDR memory again. The IC driver means that the decompressed image data is read from the DDR memory according to chip timing requirements to drive and control a target display area of the display screen for image display. 
     In summary, in the system for processing data provided by the embodiment, the system controller compresses the target image data to meet a output bandwidth of the output portal and then outputs the compressed image data through the output portal, the mudure controller decompresses the compressed image data and stores the compressed image data in the memory, and reads the decompressed image data of the corresponding mudure controller to drive and control the target display area for image display, so that the limitation of transmission bandwidth of a single network line is eliminated, the loading requirement of a 1080P display screen loaded by the single network line is met, and a situation where a large-resolution display screen is loaded by too many network lines in the related art is avoided, the use of wires is reduced, and the cost is saved; the method has the advantages that tedious steps of determining various connection line relationships during screen configuration are avoided, workload is reduced for the working staff, efficiency is improved, cross connection of a plurality of wires is avoided, stability of a system is improved, aesthetic feeling is improved, which is advantageous for the popularization and use of a display screen is improved, which is advantageous for the popularization and use of a display screen.
