【第一实施例】
参加图1，本申请第一实施例提出一种数据处理方法。如图1所示，本申请第一实施例提出的数据处理方法例如包括步骤S11至步骤S15。
步骤S11：接收输入的图像数据；
步骤S12：将所述图像数据存储至存储器中；
步骤S13：根据输出网口的带载区域信息从所述存储器中读取目标图像数据，其中，所述输出网口电连接显示屏，且所述输出网口的所述带载区域信息表征所述显示屏的目标显示区域；
步骤S14：对所述目标图像数据进行压缩处理以将所述目标图像数据的数据量降低至满足所述输出网口的输出带宽，得到以多个图像数据包表征的压缩图像数据；
步骤S15：将所述压缩图像数据经由所述输出网口输出。
具体地，步骤S11中提到的图像数据例如为DVI格式的图像数据或者HDMI格式的图像数据。步骤S12中提到的存储器例如为动态随机存储器。举例而言，例如为DDR存储器。
步骤S13中提到的带载区域信息表征显示屏的目标显示区域，举例而言，带载区域 信息例如包括输出网口带载的目标显示区域待显示的图像起始坐标以及图像宽度和图像高度。提到的目标显示区域的分辨率大小例如为1080P或者更大。提到的显示屏例如为拼接式显示屏，举例而言，由多个显示单元拼接形成的，其中每个显示单元包括多个显示模组，单个显示模组包括多个LED灯点。显示屏例如为LED显示屏。显示屏的目标显示区域例如由级联的多个模组控制器驱动控制，且级联的多个模组控制器中的第一级模组控制器通过线缆连接提到的输出网口。
步骤S14提到的压缩处理例如包括改变所述目标图像数据中每一像素数据的编码格式。压缩处理可以支持图像数据低延迟视觉无损压缩，其例如是运用JPEG2000等图像压缩算法。举例而言，当输出网口的输出带宽为1Gbps，将目标图像数据进行压缩处理后将其传输的数据量降低至1024Mbit以下。当然本申请实施例并不限制输出网口的输出带宽，当输出带宽为5Gbps时，压缩处理情况类似。
进一步地，提到的图像数据包中例如包括级联的多个模组控制器中相对应的模组控制器的标识码。图像数据包中的标识码可以保证该输出网口下的每个模组控制器精确识别出自身所要带载的图像数据，以保证每个模组控制器能够准确拿到自己所控制的那部分图像数据。模组控制器接收图像数据包以后，解析出模组控制器标识码，将其与本地标识码进行比对，如果两个标识码相同即可确定传输过来的图像数据包是自身所要带载的图像数据。
为了更好地理解本实施例，下面结合图2对本实施例提出的数据处理方法的具体实现方式进行说明。本实施例提出的数据处理方法实现在系统控制器中，其中图2为实现本实施例所述方法的系统控制器的数据流示意图。
具体地，在系统控制器中，视频接口解析表示接收输入的图像数据并对图像数据进行解码操作。输入的图像数据例如DVI格式或HDMI格式。写内存表示将图像数据缓存到DDR存储器中，然后读内存表示根据对应目标显示区域的带载区域信息从DDR存储器保存的图像数据中读取出目标图像数据。提到的带载区域信息包括该网口下目标显示区域待显示的图像坐标及图像宽高。此处考虑到异形显示屏配置的不规则性，为了减小带宽浪费，可以以显示单元即每个模组控制器的带载区域为单位进行图像数据的读取及比特截取，当然也可以以单个网口的带载区域为单位进行图像数据的读取，本实施例并不限制读取图像数据的单位。压缩表示将读取出的目标图像数据通过压缩算法进行压缩处理，以降低传输的数据量。此外，为了满足1080P的10bit视频源输入的显示屏的带载，此时1080P显示屏的10bit输入源的传输带宽可计算为1920*1080*60*10*3＝3.74Gpbs，其中1920*1080表示显示屏的分辨率，60表示帧频，10表示输入视频源的位深，3表示RGB三基色，当网线传输带宽为1Gpbs时，需要压缩 算法可以支持图像数据的四倍无损压缩。当然当输入视频源的位深更高，例如12bit时，则对应的压缩算法可以支持更高的压缩比，同时保证视觉无损。提到的压缩处理例如是改变目标图像数据中每一像素数据的编码格式，以将目标图像数据的传输数据量降低至满足网口的输出带宽。经过压缩处理得到的压缩图像数据是以多个图像数据包来表征的。网口输出表示将压缩图像数据经由网口输出至模组控制器。
进一步，在压缩图像数据输出之前，为了保证该网口下的模组控制器都能识别到自身所带载的图像数据，还可以在图像数据包中加入对应模组控制器的标识码，此时对应的图像数据包例如是以每个模组控制器的带载区域为单元进行压缩得到的。
综上所述，本实施例提出的数据处理方法通过将目标图像数据进行压缩处理以将所述目标图像数据的数据量降低至满足所述输出网口的输出带宽后经由输出网口输出，解决了单根网线传输带宽的局限性，满足了单根网线带载1080P显示屏的带载需求，避免现有相关技术中使用数量过多的网线带载大分辨率显示屏的情况，减少线材使用，节约成本；避免配屏时需要确定多种连线关系的繁琐步骤，为相关工作人员减轻工作量，提高效率，避免使用多根线材交叉连接的情况，提高系统的稳定性，提升美感，有利于显示屏的推广使用。

【第四实施例】
参见图6，本申请第四实施例提出一种数据处理方法。如图6所示，数据处理方法例如包括步骤S41至步骤S45。
步骤S41：经由输入网口接收图像数据包，得到压缩图像数据，其中所述输入网口为电连接显示屏的目标显示区域的模组控制器上的网口；
步骤S42：对所述压缩图像数据进行解压处理，得到解压图像数据；
步骤S43：将所述解压图像数据保存至存储器中；
步骤S44：从所述存储器中读取对应所述模组控制器的解压图像数据；
步骤S45：根据读取的对应所述模组控制器的所述解压图像数据驱动控制所述显示屏的所述目标显示区域进行图像显示。
具体地，在步骤S41中，提到的图像数据包中包括压缩图像数据，或者包括压缩图像数据和模组控制器标识码。提到的显示屏例如为拼接式显示屏，显示屏由多个显示单元拼接形成的，其中每个显示单元包括多个显示模组，每个显示模组包括多个LED灯点。其中显示屏例如为LED显示屏。
步骤S42中提到的解压处理例如将所述目标图像数据中每一像素数据的编码格式恢复到压缩处理之前的编码格式。步骤S43中提到的存储器例如为动态随机存储器，举例而言，例如为DDR存储器。步骤S45中提到的目标显示区域的分辨率大小例如为1080P或者更大。显示屏的目标显示区域例如由级联的多个模组控制器驱动控制。步骤S45例如包括：对读取的对应所述模组控制器的所述解压图像数据进行亮色度校正和色域调整处理得到校正图像数据；根据所述校正图像数据驱动控制所述显示屏的所述目标显示区域进行所述图像显示。
进一步地，当图像数据包中包括模组控制器标识码时，如图7所示，在步骤S42之前例如还包括步骤S411和步骤S412。
步骤S411：解析所述图像数据包中包含的模组控制器标识码；
步骤S412：判断所述模组控制器标识码和本地标识码是否匹配，以用于确定是否进行所述解压处理。
此时的图像数据包例如是以每个模组控制器的带载区域为单元进行压缩的。其中，当判断模组控制器标识码和本地标识码匹配，即控制器标识码和本地标识码相同时，进行解压处理。若判断模组控制器标识码和本地标识码不匹配，即控制器标识码和本地标识码不相同时，不进行解压处理，将接收的图像数据包转发至与所述模组控制器级联的下一级模组控制器。当判断模组控制器标识码和本地标识码匹配时，对压缩图像数据进行解压处理得到的解压图像数据就是对应模组控制器的解压图像数据。
进一步地，当图像数据包中不包括模组控制器标识码时，此时图像数据包例如是以网口为单元进行压缩的，此时对压缩图像数据进行解压处理得到的解压图像数据为对应多个模组控制器的解压图像数据并非只包括对应此模组控制器的解压图像数据。如此一来，步骤S44例如包括：对所述解压图像数据进行截取操作得到对应所述模组控制器的所述解压图像数据。其中对解压图像数据进行截取操作例如为根据模组控制器带载区域的起始坐标、宽度和高度对解压图像数据进行截取。以及在步骤S42之前还包括：将所述图像数据包转发至与该模组控制器级联的下一级模组控制器。下一级模组控制器接收到图像数据包后进行解压处理和图像数据截取等操作。
需要说明的是，本实施例提供的数据处理方法是从模组控制器的角度考虑，第一实施例提供的数据处理方法是从系统控制器的角度考虑。
为了更好地理解本实施例，下面结合图8对本实施例提出的数据处理方法的具体实现方式进行说明。本实施例提出的数据处理方法实现在模组控制器中，其中图8为实现本实施例所述方法的模组控制器的数据流示意图。

另一方面，当模组控制器接收传输过来的图像数据包中包括模组控制器标识码时，网口解析还表示对图像数据包进行解包得到模组控制器标识码，此时，会先判断模组控制器标识码和本地标识码是否匹配，若模组控制器标识码和本地标识码不相同，则代表 传输过来的图像数据包不是属于该模组控制器的，则不能进行解压处理，需要将传输过来的图像数据包传递至级联的下一个模组控制器中。若模组控制器标识码和本地标识码相同，则表示可以进行解压处理。解压表示对压缩图像数据进行缓冲和解压处理得到解压图像数据。写内存表示将解压图像数据保存至DDR存储器中。读内存表示从DDR存储器中读取对应模组控制器的解压图像数据，此处提到的对应模组控制器的解压图像数据为DDR存储器中保存的全部解压图像数据。校正表示对解压图像数据进行亮色度校正和色域调整处理后重新存入DDR存储器中。IC驱动表示按照芯片时序要求从DDR存储器中读取解压图像数据驱动控制显示屏的目标显示区域进行图像显示。

为了更好地理解本实施例，下面结合图12对本实施例提出的数据处理系统的具体工作过程进行说明。图12为本实施例提出的数据处理系统的数据流示意图。
具体地，在系统控制器中，视频接口解析表示接收输入的图像数据并对图像数据进行解码操作。输入的图像数据例如DVI格式或HDMI格式。写内存表示将图像数据缓存到DDR存储器中，然后读内存表示根据对应目标显示区域的带载区域信息从DDR存储器保存的图像数据中读取出目标图像数据。提到的带载区域信息包括该网口下目标显示区域待显示的图像坐标及图像宽高。此处考虑到异形显示屏配置的不规则性，为了减小带宽浪费，可以以显示单元为单位进行图像数据的读取及比特截取，或者以单个网口的带载区域为单元进行图像数据的读取，本实施例并不限制读取图像数据的单位。压缩表示将读取出的目标图像数据通过压缩算法进行压缩处理，以降低传输的数据量。此外，为了满足1080P的10bit视频源输入的显示屏的带载，此时1080P显示屏的10bit输入源的传输带宽可计算为1920*1080*60*10*3＝3.74Gpbs，其中1920*1080表示显示屏的分辨率，60表示帧频，10表示输入视频源的位深，3表示RGB三基色；当网线传输带宽为1Gpbs时，需要压缩算法可以支持图像数据的四倍无损压缩。当然当输入视频源的位深更高，例如12bit时，则对应的压缩算法可以支持更高的压缩比，同时保证视觉无损。提到的压缩处理例如是改变目标图像数据中每一像素数据的编码格式，以将目标图像数据的传输数据量降低至满足网口的输出带宽。经过压缩处理得到的压缩图像数据是以多个图像数据包来表征的。网口输出表示将压缩图像数据经由网口输出至模组控制器。
进一步，在压缩图像数据输出之前，为了保证该网口下的模组控制器都能识别到自身所带载的图像数据，还可以在图像数据包中加入对应模组控制器的标识码。

另一方面，当模组控制器接收传输过来的图像数据包中包括模组控制器标识码时，此时的图像数据包例如以每个模组控制器的带载区域为单元进行压缩得到的。网口解析还表示对图像数据包进行解包得到模组控制器标识码，此时，模组控制器会先判断模组控制器标识码和本地标识码是否匹配，若模组控制器标识码和本地标识码不相同，则代表传输过来的图像数据包不是属于该模组控制器的，则不能进行解压处理，需要将传输过来的图像数据包传递至级联的下一个模组控制器中。若模组控制器标识码和本地标识码相同时，则表示可以进行解压处理。解压表示对压缩图像数据进行缓冲和解压处理得到解压图像数据。写内存表示将解压图像数据保存至DDR存储器中。读内存表示从DDR存储器中读取对应模组控制器的解压图像数据，此处提到的对应模组控制器的解压图像数据例如为DDR存储器中保存的全部解压图像数据。校正表示对解压图像数据进行亮色度校正处理后重新存入DDR存储器中。IC驱动表示按照芯片时序要求从DDR存储器中读取解压图像数据驱动控制显示屏的目标显示区域进行图像显示。
