本申请涉及通信技术领域，尤其涉及一种视频信号处理方法及设备。
背景技术
低压差分小型计算机系统接口信号(全称low voltage differential SCSI，简称LVDS)和V by One是现有技术中的常用接口。其中，V by One是一种新近兴起的高速串口通讯标准，是专门面向图像传输开发出的数字接口标准。V by One的发起公司为THINE，v-by-one接口的意思是“video by one”，即通过“一根线”来传输低压差分小型计算机系统接口信号(全称low voltage differential SCSI，简称LVDS)或晶体管-晶体管逻辑(全称TransistorTransistorLogIC，简称TTL)信号。具体地，V by One信号的输入输出水平采用LVDS(低电压差动信号)。板卡的信号频率约为1GHz。与此前的互补性氧化金属半导体(Complementary Metal-Oxide Semiconductor，简称CMOS)/逻辑门电路(Transistor-TransistorLogic，简称TTL)方式相比，可将传输线的数量减少至此前的大约1/10。通俗的说就是减少了印刷电路板(全称Printed Circuit Board，简称PCB)布线，因此在大屏上的应用尤其突出。
V by One和高清晰多媒体接口(High Definition Multimedia Interface，以下简称HDMI)采用的转换极低损耗微分信号(Transition Minimized Differential Signaling，简称TMDS)相近的技术它的优点是CLK(时钟信号)是叠加在数据信号上，以共模方式传输的。这样和HDMI相比，又可以省去CLK信号线。由于通常传输距离比较近,所以对传输线材要求很低。
V by One利用1对线缆来传输高画质影像的新技术，由1到8组讯号配对组合，每组讯号的最大传输速度为3.75Gbps/秒，总体讯号线输出从4pin到18pin左右。另外，V by One的IC支持二条顺向通道；支持最高4K×2K、更新频率240Hz、每个色彩12位。特别的是，V by One也将支持各种3D影像讯号与媲美电影院的高画质解析，例如纵横比为21：9、像素为2560×1080 的影像讯号传输。
V by one接口主要用在大屏显示，例如，智能型电视、多功能打印机、防盗监控录像机以及车用导航、倒车后视系统等影像传输装置的数据通讯、高清电视、防盗监控录像、电脑、摄像机安全等方面。
产品发布是要将产品的功能展现出来，例如，智能电视等进行产品发布时，需要将向观众展示通过什么操作智能电视能够实现什么功能。如果是对打印机或者车用导航等类似产品进行产品发布，也同样，需要向观众展示通过何种控制能够具体地操作产品。
由于产品发布参与的人多、场地大，要向多个人展示发布的产品，可能需要用很多个产品，分别演示，但这样的缺点是，不同的产品的演示很难同步。现有技术还会采用在用产品展示的同时，通过舞台大屏幕显示发布的产品展示的画面。以采用V by One信号的智能电视为例，当展示者利用遥控器控制电视时，电视的显示器显示相应的画面，此时，由于舞台大屏幕不能同步显示电视的画面，而电视画面较小，观众无法直观的体验智能电视的各种功能。现有技术还在使用现场摄像机拍摄，摄像机对着电视拍摄，将电视画面投放到大屏幕，这样的缺点是图像效果不清晰。
现有技术中当需要采用另外的屏幕对产品展示时，产品的信号不能清晰的同步到需要展示的显示屏上。
发明内容
有鉴于此，本申请解决的技术问题之一在于提供一种视频信号处理方法及设备，用以解决现有技术中无法将产品信号清晰的同步展示到其他显示屏上的问题。
本申请提供一种视频信号处理方法，包括：发送经视频设备的视频信号处理器处理的第一格式视频信号；处理第一格式视频信号，使得视频信号转变为HDMI格式视频信号或者DVI(Digital Visual Interface)格式视频信号；发送转化后的HDMI格式视频信号或者发送转化后的DVI格式视频信号，以便显示器显示HDMI格式视频信号或DVI格式视频信号。
本申请还提供一种视频信号处理设备，包括：第一发送模块，设置为发送经视频设备的视频信号处理器处理的第一格式视频信号；处理模块，设置为处理第一格式视频信号，使得视频信号转变为HDMI格式视频信号或者 DVI格式视频信号；第二发送模块，设置为发送转化后的HDMI格式视频信号或者发送转化后的DVI格式视频信号，以便显示器显示HDMI格式视频信号或DVI格式视频信号。
本申请还提供一种在其上记录有用于执行上述方法的程序的计算机可读记录介质。
由以上技术方案可见，本申请提供的信号处理方法及设备，通过将视频设备的处理器发出的视频信号转化为HDMI格式视频信号或者DVI格式视频信号，使得视频设备显示屏之外的显示屏可以显示对应的视频，从而使得视频设备之外的显示屏能够同步清晰的显示视频设备处理器发出的视频信号。
附图说明
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中记载的一些实施例，对于本领域普通技术人员来讲，还可以根据这些附图获得其他的附图。

具体实施方式
本申请提供的信号处理方法及设备，通过将视频设备的处理器发出的视频信号转化为HDMI格式视频信号或者DVI格式视频信号，使得视频设备显示屏之外的显示屏可以显示对应的视频，从而使得视频设备之外的显示屏能够同步清晰的显示视频设备处理器发出的视频信号。
当然，实施本申请的任一技术方案必不一定需要同时达到以上的所有优点。
为了使本领域的人员更好地理解本申请中的技术方案，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，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都应当属于本申请保护的范围。
图1为本申请视频信号处理方法一实施例流程图。根据图1所示，本申请实施例一种视频信号处理发明方法，包括以下步骤：
步骤110，发送经视频设备的视频信号处理器处理的第一格式视频信号；
视频设备通常包括主板和显示器，主板用来做信号处理以及各种视频信号的处理，显示器显示经过处理的各种视频信号。即，通常是将经过视频设备的主板的视频信号处理器处理过的视频信号发送给显示屏进行显示。
在本申请实施例中，需要经过视频设备的主板的视频信号处理器处理过的视频信号发送到其他的设备进行处理显示，因此在本步骤中，发送经过视频设备的主板的视频信号处理器处理过的第一格式视频信号。
步骤120，处理第一格式视频信号，使得视频信号转变为HDMI格式视频信号或者DVI格式视频信号；
接收步骤110中发送的第一格式视频信号，对其进行转化处理。在本步骤中，将步骤110中发送的第一格式视频信号转化处理成HDMI格式视频信号；或者，在本步骤中，将步骤110中发送的第一格式视频信号转化处理成DVI格式视频信号。
可以理解的是，DVI是数字视频接口(Digital Video Interface)，设置为接收主机输出的全数字视频信号。使用DVI接口的显示器可以直接接收全数字视频信号，无需进行转换，从而最大限度的减少了视频信号的损失，可以获得高质量的显示效果。
HDMI(高清晰度多媒体接口)是首个也是业界唯一支持的不压缩全数字的音频/视频接口。HDMI通过在一条线缆中传输高清晰、全数字的音频和视频内容，极大简化了布线，为消费者提供最高质量的家庭影院体验。HDMI在单线缆中提供任何音频/视频源(如机顶盒、DVD播放机或A/V接收器)与音频和/或视频监视器(如数字电视DTV)之间的接口。
在本步骤中，将第一格式视频信号处理转变为HDMI格式视频信号或者DVI格式视频信号。
步骤130，发送转化后的HDMI格式视频信号或者发送转化后的DVI格 式视频信号，以便显示器显示HDMI格式视频信号或DVI格式视频信号。
在本步骤中，发送步骤120中转化得到的HDMI格式视频信号，使得该转化后的HDMI格式视频信号能够被识别，以便显示器显示该HDMI格式视频信号；或者，在本步骤中，发送步骤120中转化得到的DVI格式视频信号，使得该转化后的DVI格式视频信号能够被识别，以便显示器显示该HDMI格式视频信号。由于在现有技术中，DVI格式视频信号和HDMI格式视频信号是非常常见和通用的，因此通过上述步骤的转化处理，使得视频设备的视频处理模块处理的第一格式视频信号能够在各种通用的设备上播放。
本申请实施例通过将视频设备的处理器发出的第一格式视频信号转化为HDMI格式视频信号或者DVI格式视频信号，使得视频设备显示屏之外的显示屏可以显示对应的视频，从而使得视频设备之外的显示屏能够同步清晰的显示视频设备处理器发出的视频信号。
具体地，在本申请实施例中，第一格式视频信号为V by One格式视频信号，或者，第一格式视频信号为LVDS格式视频信号。
即，步骤110中视频设备的视频信号处理器处理的第一格式视频信号是V by One格式视频信号或者，在步骤110中，视频设备的视频信号处理器处理的第一格式视频信号为LVDS格式视频信号。
本申请还提供一种在其上记录有用于执行上述方法的程序的计算机可读记录介质。
所述计算机可读记录介质包括用于以计算机(例如计算机)可读的形式存储或传送信息的任何机制。例如，机器可读介质包括只读存储器(ROM)、随机存取存储器(RAM)、磁盘存储介质、光存储介质、闪速存储介质、电、光、声或其他形式的传播信号(例如，载波、红外信号、数字信号等)等。
图2为本申请视频信号处理方法另一实施例流程图。根据图2所示，本申请实施例一种视频信号处理发明方法，包括以下步骤：
步骤210，接收第二格式视频信号，第二格式视频信号为数字视频信号。
在本步骤中，视频设备接收不同来源的视频信号，这些视频来源可能来源于电视直播台，或者轮播台，或者点播台，或者来自网络以及USB或者DVD等外接输入，对此本申请不进行限定。下面以直播、轮播、点播和网络节目进行说明。
直播，即Broadcast TV，是各个卫星接收到片源，然后以电视台频道的形式播到各用户家庭，一般通过组播技术(IGMP,Internet Group Management Protocol、PIM,Protocol Independent Multicast)发送，保证每家每户都能够看到同样的节目，如CCTV、各地方台卫视等，以前模拟电视、数字电视。
轮播是同样的片源循环播放，片源一般放在运营商的IPTV(Internet Protocol Television)平台中。对于传统电视的广播形态，由于用户不能控制节目播出顺序，播放时间就成了广播形态中节目编排中最需要考虑的因素。把最好和最吸引观众的节目放在黄金时段(如各类综艺节目、热播电视剧)，根据不同时间的不同受众，安排诸如早安中国、午夜剧场等不同内容，以吸引该时段的目标观众。而在其他时段，则安排一些电视购物广告或人气相对不高的节目。
点播，顾名思义，就是你点了它才播，一般各运营商的点播都在一个独立于直播频道的彩电中，一旦点击了相关节目后，媒体流通过独立的媒体通道RTSP(Real Time Streaming Protocol)建立连接、发送到用户的机顶盒。
网络节目来自网络，本地节目通常来自本地的各种输入接口，例如USB接口，VCD接口等。
上面列举的这些视频信号都是采用常用的视频格式，在本申请中并不对此进行限定。

具体地，在步骤210中，第二格式视频信号为MHL(Mobile High-Definition Link)格式视频信号；或者，第二格式视频信号为DP(DisplayPort)格式视频信号；或者，第二格式视频信号为USB格式视频信号。

本步骤发送转化后的HDMI格式视频信号或者发送转化后的DVI格式视频信号，以便显示器显示HDMI格式视频信号或DVI格式视频信号，具体实施方法可以参见图1对应的实施例的步骤130。
本申请实施例通过将视频设备的处理器发出的第一格式视频信号转化为HDMI格式视频信号或者DVI格式视频信号，使得视频设备显示屏之外的显示屏可以显示对应的视频，从而使得视频设备之外的显示屏能够同步清晰的显示视频设备处理器发出的视频信号。
本申请还提供一种在其上记录有用于执行上述方法的程序的计算机可读记录介质。
所述计算机可读记录介质包括用于以计算机(例如计算机)可读的形式存储或传送信息的任何机制。例如，机器可读介质包括只读存储器(ROM)、随机存取存储器(RAM)、磁盘存储介质、光存储介质、闪速存储介质、电、光、声或其他形式的传播信号(例如，载波、红外信号、数字信号等)等。
