从以上技术方案可以看出，本申请实施例具有以下优点：
本申请第一方面提供了一种拼接墙信号同步方法，包括：接收第一帧信号；通过空分交换方式，将所述第一帧信号传输至各个显示单元，使得所述显示单元根据各自的分割边界信息，对所述第一帧信号进行图像分割，得到第二帧信号，再根据所述第二帧信号进行显示。
本申请基于先传输后分割的处理方式，通过将各个显示单元需要显示的各个帧图像作为第一帧信号整体，以整体状态进行外部公共网络传输，使得第一帧信号中的各个帧图像能够在经过相同的网络时延后被接收端接收，再通过空分交换的传输方式，将接收到第一帧信号进一步并行传输至各个显示单元，使得显示单元能够同时接收到第一帧信号，以进行后续的分割操作和显示操作，消除了现有的先分割后传输的处理方式导致各个帧图像在公共网络传输过程中的时延差，解决了现有技术由于外部网络环境影响，从信号源端信号到各个显示节点的时延不一致，而导致的画面显示不同步的技术问题。
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其它的附图。
图1为本申请提供的一种拼接墙信号同步方法的第一个实施例的流程示意图；
图2为本申请提供的一种拼接墙信号同步方法的第二个实施例的流程示意图；
图3为本申请提供的一种拼接墙信号同步装置的第一个实施例的结构示意图。
现有的拼接墙IP视频信号在编码端解码后，按输出显示节点的画面内容需求，分别切割好相应的画面通过网络信号传送到各个显示节点处理。由于同一个分割后的画面途径不同的网路路径达到各个显示节点，网络环境差异使得不同显示单元在网络传输环节的时延往往有几毫秒到几百毫秒的差异，导致各显示节点间所接收的内容存在先后差异，
本申请实施例提供了一种拼接墙信号同步方法及装置，用于解决由于外部网络环境影响，从信号源端信号到各显示节点的时延往往不一致，最终导致不同各个显示单元的画面显示不同步的技术问题。
空分交换，又名空分复用，以一个简单的例子说明，如把空间分几份，各自管各自的。把一条路分成多条，每个人走自己的路。所以每个人走路时间上是连续的。
为使得本申请的发明目的、特征、优点能够更加的明显和易懂，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，下面所描述的实施例仅仅是本申请一部分实施例，而非全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
请参阅图1，本申请第一个实施例提供了一种拼接墙信号同步方法，包括：
步骤101、接收第一帧信号；
步骤102、通过空分交换方式，将第一帧信号传输至各个显示单元，使得显示单元根据各自的分割边界信息，对第一帧信号进行图像分割，得到第二帧信号，再根据第二帧信号进行显示。
需要说明的是，本实施例当接收到前端的信号源通过网络交换发送过来的整体视频帧信号——第一帧信号，然后通过空分交换方式将接收到第一帧信号进一步并行传输至各个显示单元，使得显示单元能够同时接收到第一帧信号，再将整体的第一帧信号分割成多个第二帧信号，以进行后续的分割操作和显示操作，其中，第一帧信号可以是由一个信号源的大型帧图像信号，也可以是多个信号源构成的组合帧图像信号。
而导致现有实现画面不同步主要原因在于传输环节的时延差异，本申请通过改进信号的传输处理机制，将各个显示单元需要显示的帧图像以一个整体帧信号的形式进行传输，当帧信号完成网络传输时，意味着所有的帧图像均完成网络传输，再以空分交换的方式传输至各个显示单元，使得帧信号能同步被传输到显示单元进行显示处理，克服了传输时延差异过大的现象，实现了画面的显示同步。
进一步地，本实施例步骤102中的通过空分交换方式，将第一帧信号传输至各个显示单元具体包括：
基于空分串行通道，将第一帧信号传输至各个显示单元，其中空分串行通道为基于高速串行总线，通过空分交换方式建立的信号通道。

进一步地，信号源可以包括：前端采集设备和/或本地存储设备，本实施例基于两种信号源，一方面可处理来自前端信号源通过网络传输的IP视频信号，另一方面可动态插入本地视频信号。将本地视频的信号直接输入到显示单元的处理节点直接进入处理环节，可减少经前端采集、编码、传输等处理环节带来的时延，提升本地视频在分布式系统环境中的体验效果。
步骤202、将第一帧信号拆分为多个原始帧信号。
步骤203、根据各个原始帧信号对应的信号源以及各个显示单元的排 列位置，结合信号源与显示单元的对应关系，对各个原始帧信号进行重组，得到重组后的第一帧信号。
需要说明的是，步骤202和步骤203提供的是对第一帧信号按照显示单元的配置情况重新调整各个帧图像的位置的步骤，以便后续进行分割时，各个帧图像能显示在设定好的显示单元中。
步骤204、通过空分交换方式，将第一帧信号传输至各个显示单元，使得显示单元根据各自的分割边界信息，对第一帧信号进行图像分割，得到第二帧信号，再根据第二帧信号进行显示。
可以理解的是，在步骤203的基础上，本实施例步骤204中的第一帧信号均特指为步骤203中重组后的第一帧信号。

本申请的说明书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本发明各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
所述集成的单元如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方 案的全部或部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本发明各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁碟或者光盘等各种可以存储程序代码的介质。
以上所述，以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
