背景技术
在很多应用场景下，固定的显示器操作是极其不便的。比如，在车间生产环节中，企业不想将数据存储在移动设备中导致泄密，因此核心数据、图纸存放在一台固定式电脑中。而工程师需要远离此电脑在机床边进行比对操作，如果采用固定显示器，这就造成了巨大的不便。而无线显示器即可通过固定电脑主机配合远距离显示器来提供显示和人机交互的服务。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例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发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明实施例提供的一种显示系统的结构示意图；
图2是本发明实施例提供的一种控制设备的结构示意图；
图3是本发明实施例提供的一种显示设备的结构示意图；
图4是本发明实施例提供的一种数字基带处理组件的结构示意图。
具体实施方式
本发明实施例提供的显示设备、控制设备以及显示系统，可以应用在无线显示器的图像传输显示产品领域中，比如对电影片场控制台输出的视频进行移动显示、对车间主机输出视频进行移动显示、实验室电脑输出的视频进行移动显示、会议室主机内容进行移动显示等。在其他的应用场景中，如果控制设备位置固定，需要用户手持显示设备对控制设备输出的视频数据或者图像数据进行移动操作的场景中，都可采用上述本发明实施例提供的控制设备、显示设备以及显示系统。
请参考图1，是本发明实施例提供的一种显示系统的结构示意图，图1所示的显示系统可包括管理设备101、控制设备102和显示设备103，其中，管理设备101可以是固定工作站比如包括电脑主机、电影片场控制台、车间主机、会议室主机等；控制设备101可以为无线显示器对应的主机端，显示设备103可以为无线显示器。管理设备101与控制设备102之间可通过USB3.1Type C接口或者线缆连接；控制设备102与显示设备103之间通过无线方式连接进行无线连接。 无线保真(Wireless Fidelity，WIFI)是目前无线图像传输的核心通信方案，但是这种通信方案比较容易受到干扰，并且无法进行远距离传输。另外，采用WIFI方式进行无线图像传输时控制设备102需要将待传输数据比如视频数据传输到云服务器上，然后显示设备103从云服务器获取上述视频数据，这样一来，导致了无线图像传输过程中的时延较高。
为了解决采用WIFI进行无线图像传输过程中存在的问题，本发明实施例中采用自研的OcySync2.0通信协议进行控制设备102和显示设备103之间的无线通信。OcySync2.0通信协议中控制设备102和显示设备103之间进行点对点通信，不用通过云端服务器，可以降低一部分传输时延。另外，OcySync2.0通信协议中规定了无线通信编解码以及后端的图像编解码，实现根据当前时刻的传输信道环境对待传输数据比如图像数据或者视频数据对应的码流进行压缩处理，使得当前时刻的传输信道可承载压缩处理后的码流；然后在接收端对码流进行解压，恢复得到图像数据，实现在低码流时转化图像。
换句话说，OcySync2.0通信协议可以实现在无线图像传输过程中，编解码自定义，基于此优点，OcySync2.0可以应用在不同的硬件平台上，满足不同应用场景下的无线数据传输要求。例如，在某种应用场景下显示设备103不可支持4K，但是控制设备传出的视频数据为4K，此种情况下，OcySync2.0通信协议中可规定编码模块将视频数据裁剪为1080P或者2K，以实现在显示设备中显示视频数据。
在图1所示的显示系统中，管理设备101用于将目标数据传输给控制设备102；控制设备102用于对接收到的目标数据进行处理得到目标码流，并将目标码流发送给显示设备103；显示设备103用于对接收到的目标码流进行处理，并根据处理后的目标码流进行显示。目标数据中包括管理设备101输出的视频数据，用户可通过显示设备103查看到管理设备101输出的视频数据，并可通过触摸屏幕或者外接输入设备比如键盘在显示设备103中输入对视频数据的控制指令。能够在不同的显示设备上实现视频数据的显示，满足不同应用场景下的无线数据传输需求。
当用户根据显示设备103显示的视频数据输入了控制指令时，显示设备103 根据用户的控制指令生成控制数据，并将控制数据发送给控制设备102；控制设备102对接收到的显示数据进行处理，并将处理后的控制数据发送给管理设备101。管理设备101根据接收到的处理后的控制数据对管理设备101输出的视频数据进行处理，以得到下一次传输的通信数据。
基于上述对显示系统的描述，本发明实施例提供了一种控制设备的结构示意图，如图2所示。图2所述的控制设备中可包括数据处理装置201和通信装置202，所述数据处理装置201与通信装置202通讯连接。
在一个实施例中，数据处理装置201用于获取目标数据，并对所述目标数据进行处理以得到整合目标数据，并将整合目标数据发送给通信装置202；通信装置202用于获取整合目标数据，并对整合目标数据进行处理，以生成目标码流，以及将所述目标码流发送给显示设备端。其中，通信装置202可包括数字基带处理组件2021，所述数字基带处理组件用于以预置估计频度进行信道质量估计得到信道质量估计结果，以使所述数据处理装置201根据所述信道质量估计结果对目标数据进行处理，使得目标码流发送给所述显示设备端的过程中，传输时延低于时延阈值。
在一个实施例中，所述数据处理装置201对所述目标数据进行处理以得到整合目标数据，可包括：所述数据处理装置对所述目标数据进行编码，以得到所述整合目标数据。此处对目标数据进行的编码可以理解为信源编码，所谓信源编码是为了去除目标数据中包括的一些冗余信息，从而可达到压缩信源输出的信息率，提高系统有效性的目的。
进一步可选的，所述数据处理装置201对所述目标数据进行编码以得到所述整合目标数据，包括：所述数据处理装置201根据所述信道质量估计结果对所述目标数据进行编码，以得到所述整合目标数据；这样一来，有利于通信装置202根据所述整合数据得到的目标码流在发送给所述显示设备端的过程中，传输时延低于时延阈值。
在一个实施例中，所述通信组件202还用于获取显示设备端发送的控制码流，并对所述控制码流进行处理得到控制数据，并将控制数据发送给数据处理装置 201，以使得所述数据处理装置201对所述控制数据进行处理，并将处理后的控制数据发送给主机端。
在一个实施例中，所述数字基带处理组件2021可包括信道估计器，通过信道估计器以预置估计频度估计信道质量得到信道质量估计结果，并将所述信道质量估计结果发送给数据处理装置，以便于所述数据处理装置201根据信道质量估计结果对目标数据进行编码处理。应当理解的，信道质量估计结果可以反映无线传输信道的干扰情况，在无线干扰较大的地方，信道质量估计结果较差，反之，在无线干扰较小的地方，信道估计结果较好。如果无线干扰较大，表明无线传输信道带宽较低，码流无法发高。信道估计器可以实时监测获取无线传输信道的污染程度，即信噪比，可以根据信噪比确定信道质量估计结果，信噪比越高表明信道质量估计结果越好；信噪比越低表明信道质量估计结果越差。
其中，预置估计频度可以是自研OcySync2.0通信协议根据当前的信道情况预先设置的预置估计频度。预置估计频度可以是毫秒级左右一次。所谓估计频度满足时延条件是指以预置估计频度进行信道质量估计并根据估计得到的估计结果进行传输时，可以使得传输时延低于时延阈值。该时延阈值可以是根据历史传输经验设定的。
在本发明实施例中，实现通过数据处理装置201根据信道质量估计结果对目标数据进行编码，达到传输目标码流的时延低于时延阈值的原理可以为：假设在信道质量正常的情况下，无线信道中可承载4K码流的速率，此时数据处理装置201可以对目标数据进行编码处理以得到整合目标数据，通信装置202再对整合目标数据进行编码处理得到目标码流，保证目标码流为4K即可。但是在无线信道中有干扰时，带宽变低后来不及发送原4K码流，因此无法在规定时间内将整合目标数据发送过去，造成时延；为了维持低时延，当信道估计器估计出数据信道中有污染时，会告知数字基带处理组件2021需要提高编码可靠性，降低编码速率。数字基带处理组件2021将信息反馈给数据处理装置201，数据处理装置201根据当前信道的受污染程度，选择更合适的方式进行低码流编码。

针对图2中所述的数字基带处理组件以及图3中所述的数字基带处理组件，本发明实施例提供了一种数据处理组件的结构示意图，如图4所示。
在一个实施例中，数字基带处理组件是基于正交频分复用技术实现的，在图2和图3的实施例中，压缩后的目标数据和配置数据可通过数字基带处理组件的数据信道进行传输，对数字基带处理组件进行操作的控制信号可通过控制信道进行传输。
在一个实施例中，数字基带处理器可包括发射端401和接收端402，发射端 401用于获取上层用户数据比如来自管理设备的目标数据以及来自显示设备的控制数据，并对获取到的数据进行物理层编码处理，将编码处理后的数据发送到空中接口；接收端402用于从空中接口接收数据，并对接收到的数据进行解码操作。
在一个实施例中，发射端401可包括比特级处理模块4011，比特级处理模块4011用于对数据信道和控制信道中传输的数据进行码块分割、CRC添加、比特级编码、码块级联、加扰码等功能；发射端401还可包括符号级处理4012，符号级处理4012用于对比特级处理模块4011处理后的比特流进行符号级处理，比如子载波映射、天线映射等；发射端401还可包括正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)调制模块4013，OFDM调制模块4013用于将符号级处理后的数据从频域转换到时域。

在一个实施例中，接收端402还可以包括同步模块4023，同步模块4023主 要用于保持发射端401和接收端402之间的同步，简单来讲，同步模块4023主要用于对发射端401和接收端402的物理层进行时间同步和频率同步，保证发射端401和接收端402处于连接状态中。换句话说，同步模块4023用于在发射端401发送数据帧，接收端402接收数据帧时，使两端互相咬合到。可选的，同步模块4023可以基于两端的数据帧中的同步符号实现两端互相咬合。具体地，同步模块4023在无线传输信道中不断搜索，找到适合的能量时间，找到数据帧中插入的同步符号，找到同步符号的位置，实现在发射端发送数据帧和接收端接收数据帧时互相咬合到。
在一个实施例中，接收端402还可以包括软比特映射模块4024，软比特映射模块4024通过搜索和合并等方式得到控制信道和数据信道的软比特；之后分别通过相应的信道解码模块对数据信道和控制信道进行解码。
在本发明实施例中，OcySync2.0通信协议中规定数据信道或者控制信道中传输的数据帧的帧长度属于亚毫秒级别，也就是说采用OcySync2.0通信协议进行无线传输时物理层的帧结构与wifi不同，正是由于物理层的帧结构和信道估计器，使得采用OcySync2.0通信协议进行无线传输，可以达到低时延的特性。
以上所揭露的仅为本发明部分实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
