图2是本发明多联屏桌面共享***一种实施例的结构框图；
图1是本发明多联屏桌面共享的方法信令流程一种实施例的流程示意图。
具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
一种多联屏桌面共享的方法，其包括步骤：S1,一个或多个终端设备向多联屏终端发送屏幕共享请求；S2，根据屏幕共享请求截取多联屏终端的屏幕桌面；S3，对屏幕桌面进行编码，通过RTP服务器发送到相应的终端设备；S4，终端设备对接收到的屏幕桌面进行解码显示。
优选的，所述屏幕共享请求为SIP请求，所述SIP请求包括INVITE消息，所述INVITE消息携带的信息包括终端设备IP、端口号、请求的屏幕编号和终端设备所支持的编解码类型。
如图2所示，步骤S1称为信令流程，具体包括子步骤：S11，一个或多个终端设备向多联屏终端发送带有INVITE消息的SIP请求；S12，所述SIP请求通过软交换服务器透传到多联屏终端；S13，所述多联屏终端收到请求后回复200OK消息；S14，所述终端设备收到200OK消息后回复ACK确认消息到多联屏终端，建立通信链路。图中实施例采用三个终端设备，分别用终端1、终端2和终端3表示。
优选的，所述步骤S3具体为：将屏幕桌面图片压缩成H264码流，通过RTP服务器打包发送到相应的终端设备。
优选的，其还包括步骤：S0，多联屏终端在软交换服务器登记本地位置。
优选的，所述多联屏终端为三联屏终端。以三联屏终端的桌面共享为例，详述本发明的工作原理如下。
本发明可以根据用户配置，三联屏中最多可同时将三个屏幕的图片，编码成H.264码流，通过RTP服务器发送到相同或不同的终端供解码显示，从而达到共享桌面的目的。
该实施例需要三联屏终端、软交换服务器、RTP服务器和三个终端设备配合来完成。
三联屏终端主要作用为：截取本地三联屏的屏幕桌面，将其编码成H.264码流，通过RTP服务器发送到待调看的终端设备，供请求桌面共享终端设备解码显示。
软交换服务器主要作用为路由分配和位置登记。三联屏终端运行起来后，需要到软交换服务器作位置登记。
业务开通过程主要是通过SIP消息来建立的，在说明中，如果涉及到私有消息定义，则可以增加特殊说明。
在三联屏共享启动过程中，屏幕共享方根据需求可将一个或多个屏幕桌面图片压缩成H264码流，通过RTP服务器打包发送到其他终端，由其他终端解码显示。
业务开通过程主要是通过SIP消息来建立的，通过SDP协议协商双方的媒体IP和端口，将编码号的H.264码流通过RTP服务器发出。
本发明方法主要包含两个部分：信令部分和媒体流传输部分。
1.信令部分
信令部分也称协商阶段，即步骤S1。
三个终端设备向三联屏终端发送SIP请求，在SIP请求的INVITE消息中使用SDP协议携带本身的IP、端口号、请求的屏幕编号和终端设备所支持的编解码类型等，INVITE消息经过软交换服务器，透传到三联屏终端。三联屏终端将请求桌面共享端媒体信息记录下。三联屏终端将请求桌面共享端媒体信息记录下并回复200OK消息（使用SDP协议）。请求端收到200OK消息后，回复ACK确认消息。
2.媒体流传输部分
媒体传输部分亦为三联屏桌面共享阶段，即步骤S2至S4。
三联屏终端方将屏幕桌面图片压缩并使用H264编码发送至对应的请求终端设备,请求端通过解码显示三联屏终端方共享的桌面。
本发明多联屏桌面共享的方法通过软交换服务器建立信令链路，通过RTP服务器建立流媒体共享链路，实现多联屏终端的多个屏幕桌面同时发送给相同或不同的请求端，同时共享三个屏幕的桌面的技术效果。
另外，本发明通过H264协议压缩抓取到的屏幕桌面并通过RTP发送到请求端，供请求端解码显示，实现简单方便，稳定可靠。
本发明可广泛应用于各种多联屏桌面共享***。
如图1所示,一种多联屏桌面共享的***，其用于实施一种多联屏桌面共享方法，其包括：多联屏终端，用于提供一个或多个屏幕桌面，分别通过软交换服务器和RTP服务器与一个或多个终端设备连接；软交换服务器，用于传输屏幕共享请求信息；RTP服务器，用于屏幕桌面媒体流信息；一个或多个终端设备，用于接收共享的屏幕桌面。
优选的，所述多联屏终端为三联屏终端。
优选的，所述一个或多个终端设备为三个终端设备。需要说明的是，终端设备的形态既可以是软终端、也可以是硬终端，只要出现的功能与本专利介绍的一致，则也在本专利的保护范围。
一种多联屏桌面共享的***的实现原理对应于一种多联屏桌面共享的方法，在此不做累述。
本发明多联屏桌面共享***通过软交换服务器建立信令链路，通过RTP服务器建立流媒体共享链路，实现多联屏终端的多个屏幕桌面同时发送给相同或不同的请求端，同时共享三个屏幕的桌面的技术效果。
本发明可广泛应用于各种多联屏桌面共享***。
以上是对本发明的较佳实施进行了具体说明，但本发明创造并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可做作出种种的等同变形或替换，这些等同的变形或替换均包含在本申请权利要求所限定的范围内。
