一种视频通话终端及含有该视频通话终端的视频通话系统 技术领域
本发明涉及一种视频通话终端及由其组成的视频通话系统，尤其是通过一键实现寻址请求的视频通话终端及其组成的视频通话系统。
 背景技术
在科技高速发展、人们生活水平不断提高的背景下，先进的视、音频通话代替传统的音频通话是大势所趋，视频电话和网络电话应运而生。但是，自视频电话问世以来，只是在个别场合予以使用（例如楼宇的防盗门门禁开关等），而广大的消费市场并没有能够真正的启动，究其原因，主要存在以下问题：现有的视频电话系统中可视屏幕太小，一般的可视屏幕都在3.5英寸以下，摄像头的拍摄角度较小，且无法与其他显示屏匹配，用户使用中需要与通话设备靠的很近才能实现视频通话；网络电话虽然比视频电话在实现视频通话方面具有一定的技术优势，在企事业单位中占据了更广泛的市场，但是，进入家庭却必须依赖于家用电脑，不仅硬件成本较高，而且需要安装相关的软、硬件才能实现，此外，即使利用家用电脑来进行视频通话，操作也比较繁琐，对于老人和孩子来说，使用并不方便。
目前，一种基于网络的操作方便的一键式视频通话终端，并未见诸报道。
 技术问题
本发明的目的在于：针对视频通话市场的需求，尤其是目前网络视频通话必须依赖于家用电脑，且操作繁琐，对于老人和孩子来说使用并不方便等一系列问题，提供一种新的视频通话终端设备及含有该设备的视频通话系统。

在本发明中：视频通话终端的盒体上设有散热孔或散热槽。
一种含有上述视频通话终端的视频通话系统，包括服务器、公共互联网，其特征在于：公共互联网至少涵盖两个网关，每个网关至少管辖两个所述的视频通话终端，所述的视频通话终端配设有摄像头、麦克风和显示屏。
在所述的视频通话系统中：所述的显示屏为液晶显示屏或等离子显示屏或数码电子相框或电视机。
在所述的视频通话系统中：发出主叫信号的视频通话终端为主叫视频通话终端，收到主叫信号的视频通话终端为被叫视频通话终端，所述的主叫视频通话终端与被叫视频通话终端同时隶属同一网关，或所述的主叫视频通话终端与被叫视频通话终端分别隶属不同的网关。
在所述的视频通话系统中：系统中各视频通话终端开机后均会自动通过网关进入公共互联网在服务器上登记对应的IP地址；通话前，主叫视频通话终端通过通话状态键开启通话通道，再由一键选址按钮输入被叫视频通话终端的IP地址，经网关向服务器申请被叫视频通话终端的IP地址，
向被叫视频通话终端发出请求信号，收到主叫视频通话终端的请求信号后，被叫视频通话终端通过通话状态键开启通话通道，主叫视频通话终端与被叫视频通话终端均进入通话状态后，分别将各自获取的音频信号和视频信号直接与对方沟通交换。
 有益效果
本发明的优点在于：本发明基于成熟的网络视频电话技术，将与网络视频电话直接相关的硬件进行优化组合，建立一种具有单一功能的终端设备，降低了网络视频电话的硬件成本；由于终端设备设有一组一键选址按钮，每个选址按钮将触发特定被叫视频通话终端的IP地址的寻址信号，使实现网络视频通话操作更加简便；由于终端上设有摄像头接口、麦克风接口，并可以与不同形式的显示屏匹配，因此，由该终端设备组成的网络视频通话系统可以使视频通话的双方根据实际情况，在更大范围内实现交流。
