步骤E.软件客户端点对点呼叫视频监控终端的号码；
步骤F.视频会议系统召开一个会议，将软件客户端和视频会议终端加入会议；
步骤G.软件客户端显示视频监控终端视频，而视频监控终端没有解码能力，多点控制单元不发送音视频给监控终端；
另外，在H323协议进行终端能力交互部分，对协议进行了扩展。标准的H323协议通讯中，媒体传输必须是双向的。而融合系统中增加了视频监控终端作为虚拟视频会议终端，虚拟终端没有视频解码能力，因此，标准协议中会出现H323能力交互失败。通过对H323能力进行扩展，使没有解码能力的终端仍然可以通过能力交互，上会成功。这种情况下，视频媒体是单向传输的。而传统的融合监控网关会伪造虚拟终端有解码能力，当视频会议系统发送媒体给它时，它不进行处理。这种方法浪费了网络带宽和服务器计算资源。
此融合系统中，还对视频会议终端和会议管理客户端进行了合并，融合的软件客户端即可创建会议室组织召开会议，还可以作为软件视频会议终端加入会议，或者与其他硬件视频会议终端或软件终端进行点对点视频会议。
图4是传统的视频会议与视频监控融合系统结构图，如图4所示，视频会议系统和视频监控系统拥有独立的视频转码单元和客户端。
图5是根据本发明实施例的视频会议与视频监控融合系统结构图，使用视频会议系统中的多点控制单元代替视频监控系统中的视频转码单元，使用视频会议系统客户端代替视频监控系统客户端。其中，多点控制单元集成了会议管理模块，提供接口供软件客户端接入创建和召集会议。
图6是根据本发明实施例的融合系统的简化结构图，如图6所示，隐藏了视频监控系统细节，视频监控终端对应在视频会议系统中为虚拟视频会议终端。
以下结合附图介绍视频会议和视频监控系统融合的具体实施方式：
1.如图5所示，图中左侧是视频会议系统组成，包括MCU多点控制单元、GK网守、视频会议终端和软件客户端。视频会议终端和MCU都注册到GK(MCU也可含内置GK配置为外置GK的邻域GK)，MCU提供会议管理接口供软件客户端连接。软件客户端即是视频会议软件终端，又作为会议管理客户端，因此软件客户端既要注册到GK，还有连接上MCU的会议管理单元。
图5右侧是视频监控系统，与图4中传统视频监控系统相比，不需要视频转码单元，也不需要独立的客户端进行视频监控。视频转码用视频会议视频中MCU编解码功能实现，同时使用同一个软件客户端进行视频监控和视频会议。
图5监控融合网关负责将视频监控终端转换为虚拟视频会议终端，并注册到GK。当MCU或者终端呼叫询视频会议终端时，监控融合网关从视频监控平台获取监控终端媒体URL地址， 然后获取监控终端音视频媒体发送给视频会议终端或MCU。
2.图7是根据本发明实施例的软件客户端进行视频监控的流程图，如图7所示，该流程包括如下步骤：
步骤S702，设置软件客户端的音视频能力(如H264/4CIF)；
步骤S704，客户端注册到GK并登陆到MCU的会议管理系统；
步骤S706，客户端从GK获取视频监控终端的列表；
步骤S708，选择需要监控的终端进行呼叫，并设置呼叫速率(如512kbps)；
步骤S710，客户端调用MCU会议管理系统接口在MCU上创建并召集一个会议，会议包含软件客户端和监控终端，会议速率为客户端呼叫监控终端的速率；
步骤S712，MCU呼叫监控终端和软件客户端，将监控终端的视频转码为软件客户端所支持的能力(如H264/4CIF)发送给软件客户端；
步骤S714，客户端收到监控终端的视频媒体，实现了视频监控。
3.图8是根据本发明实施例的多点控制单元呼叫视频会议/监控终端的流程图，如图8所示，描述了上述步骤S712中MCU呼叫监控终端/视频会议终端(包括硬件终端和软件终端，即软件客户端)的流程。与呼叫视频会议终端有不同，监控终端所对应的虚拟视频会议终端没有视频解码能力，正常H323能力协商不能通过，本发明可选实施例对H323能力进行扩展，使这种情况也能通过能力协商。如图8所示：
步骤S802，MCU开始会议，呼叫终端；
步骤S804，与终端进行扩展H323能力协商；
步骤S806，判断终端是否有视频解码能力，当终端有解码能力时，为视频会议终端，执行下一步，否则，跳转到步骤S816；
步骤S808，正常上会模式，向终端发送视频媒体；
步骤S810，判断会议中视频会议终端个数是否只有1个，如果是，执行S812，否则，执行S814；
步骤S812，MCU对此视频会议终端进行流控，使终端发送视频速率为0；
步骤S814，正常上会模式，对终端接收视频流进行解码；
步骤S816，视频监控模式，不向终端发送视频，只接收其音视频流。
图9是根据本发明实施例的软件客户端进行视频监控时，视频流的传送方向示意图，如图9所示，此时视频媒体从监控终端传送到MCU，经过转码、合成等处理后再发送给视频会议终端，视频媒体为单向传输，与传统监控客户端监控相同，但是本发明的方法可以实现多 路同时监控；
6b)MCU对此视频会议终端不进行流控，按照会议速率从终端接收视频媒体处理后发送给其他视频会议终端。
图10是根据本发明实施例的软件客户端与其他视频会议终端进行视频会议(包含视频监控终端)，视频流的传送方向示意图。如图10所示，这种情况下，视频会议终端视频媒体双向传输，监控终端视频媒体为单向传输。
6c)终端没有视频解码能力，MCU认为此终端为监控终端，监控终端可以上会向MCU发送音视频媒体，但是MCU不向监控终端发送音视频媒体。传统方法中，MCU发送视频媒体给监控融合网关，融合网关不处理。与传统方法相比，本发明实施例的方法减少性能损耗同时节约网络带宽。
综上所述，通过本发明实施例的融合系统中省去了视频监控系统中的视频转码单元，使用MCU的编解码能力实现视频转码，同时也省去了视频监控客户端，使用视频会议客户端代替实现视频监控功能。同时，还能利用MCU视频合成能力，使客户端可以同时进行多个端的监控。
