第二解码器122负责对专用的高码流网络传输过来的高质量低延时视频信号流进行解码，将解码后的图像和音频信号直接输出给视频处理模块13，该第二解码器122可以支持4:4:4高色深低压缩的1080P@60Hz或4k@30Hz的视频解码，同时第二解码器122与控制模块14通信连接，由控制模块14管理和控制第二解码器122的功能配置、解码过程和内部状态反馈等。
进一步地，网络交换模块11设有至少一个第一网口、至少一个第二网口和至少一个第三网口。
第一网口用于传输H264/H265视频信号流，第二网口用于传输低延时视频信号流，第三网口用于传输第二控制信号流。第一控制信号流可以通过第一网口或第二网口输出，对相应的坐席系统进行控制。
综上所述，上述实施例提供的视频信号流转换装置10，突破了市面上现有技术，打破了网络坐席系统20和光纤坐席系统30之间的通信壁垒。通过该视频信号流转换装置10可以让网络坐席系统20转换成光纤坐席系统30，并且在授予权限的情况可以通过光纤坐席系统30去控制网络坐席系统20的主机，极大地提高了网络坐席系统20操作人员和光纤坐席系统30操作人员之间的沟通效率。
在本申请的另一实施例中，还提供了一种坐席协作系统，包括网络坐席系统20、光纤坐席系统30和如上任一实施例提供的视频信号流转换装置10。
网络坐席系统20输出的网络视频信号流通过视频信号流转换装置10传输 给光纤坐席系统30；光纤坐席系统30输出的第一控制信号流通过视频信号流转换装置10传输给网络坐席系统20，并对网络坐席系统20进行相应控制。
进一步地，网络坐席系统20包括能够输出H264/H265视频信号流的第一坐席系统21和能够输出低延时视频信号流的第二坐席系统22；
第一坐席系统21通过网络交换模块11的第一网口与网络交换模块11通信连接，第二坐席系统22通过网络交换模块11的第二网口与网络交换模块11通信连接。
进一步地，坐席协作系统还包括：
配置管理模块40，与视频信号流转换装置10的网络交换模块11通信连接，用于输出第二控制信号流，视频信号流转换装置10的控制模块14用于根据第二控制信号流对视频信号流转换装置10的网络交换模块11、视频解码模块12和视频处理模块13进行相应管理及控制。
由于具体的实现原理已经在上述实施例中阐明，此处不再赘述。
本实施例提供的坐席协作系统，不仅可以实现将网络坐席系统20的视频实时显示在光纤坐席系统30中和实现光纤坐席系统30对网络坐席系统20的控制，而且分别单向传输也可以提高数据传输效率及保持光纤坐席系统30的控制权限更高，便于系统安全管理。
以上所述，以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
