所述信号转换处理器10包括终端连接接口11及转换处理单元12，所述信号转换处理器10通过所述终端连接接口11与所述第一终端进行有线通信连接以进行数据信息交互，所述转换处理单元12对所述终端连接接口11所输入的屏幕显示信息进行转换处理得到数据信号；所述信号无线发射器20包括数据信号传输接口21、编码单元22及无线网络天线23，所述信号无线发射器20通过所述数据信号传输接口21以插接的方式与所述信号转换处理器10相连接，所述编码单元22用于对所述数据信号传输接口21所输入的所述数据信号进行编码得到编码信号，所述无线网络天线23用于将所述编码信号发送至所述第二终端。其中，数据信号传输接口21可作为公头，信号转换处理器10中包含与公头对应的母座，将公头插入母座内，即可实现将信号转换处理器10与数据信号传输接口21进行插接；所述无线网络天线23可以是5G网络天线、蓝牙天线或WIFI天线。
其中，所述数据信号传输接口21与所述终端连接接口11为不同类型的接口，具体的，数据信号传输接口21可以是高清多媒体信号输入接或显示信号传输接口(DP接口，DisplayPort接口)，终端连接接口11可以是USB信号传输接口、Type-C信号传输接口或显示信号传输接口(DP接口，DisplayPort接口)。
在更具体的实施例中，所述终端连接接口11为Type-C信号传输接口，所述转换处理单元12为Type-C信号转换处理单元，所述转换处理单元12的输出端连接所述数据信号传输接口21。Type-C信号传输接口可与包含Type-C信号输出接口的第一终端进行连接，Type-C信号传输接口输入高清多媒体信号(HDMI信号)，高清多媒体信号中包括音频信号及视频信号(简称音视频信号)，Type-C信号传输接口同时还可以其它控制数据，例如其它控制数据可以是触控数据。若Type-C信号传输接口输入的数据为控制数据，则可直接输出至编码单元22进行编码后无线发送至第二终端；若Type-C信号传输接口输入的HDMI信号，需判断编码单元22是否支持直接对HDMI信号进行编码操作，若编码单元22支持直接对HDMI信号进行编码操作，则可将HDMI信号输出至编码单元22进行编码后无线发送至第二终端；若编码单元22不支持直接对HDMI信号进行编码操作，则需通过Type-C信号转换处理单元将HDMI信号转换为编码单元22所支持的格式类型，之后再将经过Type-C信号转换处理单元进行转换处理后的信号输出至编码单元22进行编码。例如，若编码单元仅支持对MIPI(视频)&I2S(音频)信号进行编码操作，则需通过Type-C信号转换处理单元将HDMI 信号转换MIPI&I2S信号，此时Type-C信号转换处理单元即为A/V转换器(A/V Converter)。
例如，其它控制数据可以是触控数据，此时第二终端可以是具有触摸功能的会议一体机，用户在第二终端上进行触控操作产生触控数据，无线网络天线23以无线通信方式接收来自第二终端的触控数据，并通过Type-C信号传输接口将触控数据传输至第一终端，第一终端可根据触控数据完成相应触控操作从而对应调整第一终端的屏幕显示内容。
更具体的，所述信号转换处理器10还包括USB转换座13，所述USB转换座13以插接的方式与所述Type-C信号传输接口相连接；此时，所述USB转换座13的USB信号传输接口作为新的终端连接接口11，则USB转换座13的USB信号传输接口可与包含USB信号输出接口的第一终端进行连接，所述USB转换座13的信号输出接口连接所述Type-C信号传输接口。通过增加USB转换座13，可进一步扩展信号无线发射器20的使用功能。此时USB转换座13的USB信号传输接口作为终端连接接口，USB信号传输接口能够同时接收HDMI信号及其它控制数据，USB转换座13的输出接口可与上述Type-C信号传输接口进行连接，具体实施方式如图2所示。USB信号传输接口通过D+/D-传输通道将控制数据传输至Type-C信号传输接口。
在更具体的实施例中，所述数据信号传输接口21为高清多媒体信号传输接口，所述终端连接接口11为Type-C信号传输接口或显示信号传输接口(DP接口，DisplayPort接口)，所述转换处理单元12为Type-C信号转高清多媒体信号处理单元或显示信号转高清多媒体信号处理单元，所述转换处理单元12的输出端连接所述高清多媒体信号传输接口21。此时，数据信号传输接口21可以是HDMI公头，则信号转换处理器10中包含与HDMI公头对应的HDMI母座，将HDMI公头插入HDMI母座内，即可实现将信号转换处理器10与数据信号传输接口21进行插接。终端连接接口11为Type-C信号传输接口或显示信号传输接口，则终端连接接口11可与包含Type-C信号输出接口或显示信号输出接口的第一终端进行连接；与此同时，若单独使用信号无线发射器20，则可通过高清多媒体信号传输接口与包含高清多媒体信号输出接口的第一终端进行连接。若终端连接接口11为Type-C信号传输接口，则转换处理单元12为Type-C信号转高清多媒体信号处理单元，Type-C信号转高清多媒体信号处理单元可用于将Type-C信号传输接口所输入的Type-C信号转换为高清多媒体信号，并进一步传 输至信号无线发射器20。若终端连接接口11为显示信号传输接口，则转换处理单元12为显示信号转高清多媒体信号处理单元，显示信号转高清多媒体信号处理单元可用于将显示信号传输接口所输入的显示信号转换为高清多媒体信号，并进一步传输至信号无线发射器20。更具体的，若编码单元22支持直接对HDMI信号进行编码操作，则无需在信号无线发射器20内设置转换处理单元用于格式转换；若编码单元22不支持直接对HDMI信号进行编码操作，则还需在信号无线发射器20内设置一个转换处理单元(如前述的A/V转换器)将HDMI信号转换为编码单元所支持的格式类型，之后再将进行转换处理后的信号输出至编码单元22进行编码。
显示信号传输接口或高清多媒体信号传输接口中并不包含D+/D-传输通道，则可使用显示信号传输接口或高清多媒体信号传输接口中空闲的针脚(pin)作为对控制数据进行传输的传输通道。
与此同时，所述信号无线发射器20还可通过所述数据信号传输接口21以插接的方式与所述第一终端进行有线通信连接以进行数据信息交互。也即是单独使用信号无线发射器20，此时，数据信号传输接口21为高清多媒体信号传输接口，可通过高清多媒体信号传输接口与第一终端进行有线通信连接以实现对高清多媒体信号的交互传输。
若终端连接接口11为显示信号传输接口(DP接口，DisplayPort接口)，还可在信号无线发射器20中设置独立USB信号传输接口24，所述独立USB信号传输接口24也可用于与第一终端进行有线通信连接以进行数据信息交互，独立USB信号传输接口通过线材与无线网络天线23相连接，无线网络天线23可接收来自第二终端的其它控制数据，并通过独立USB信号传输接口24传输至第一终端，具体实施方式如图3所示。例如，其它控制数据可以是触控数据，此时第二终端可以是具有触摸功能的会议一体机，用户在第二终端上进行触控操作产生触控数据，无线网络天线23以无线通信方式接收来自第二终端的触控数据，并通过独立USB信号传输接口24将触控数据传输至第一终端，第一终端可根据触控数据完成相应触控操作从而对应调整第一终端的屏幕显示内容。与此同时，若单独使用信号无线发射器20，则可通过高清多媒体信号传输接口与包含高清多媒体信号输出接口的第一终端进行连接，通过独立USB信号传输接口24与第一终端进行有线通信连接以进行数据信息交互。
若终端连接接口11为Type-C信号传输接口，还可在所述信号转换处理器 10还中设置USB转换座13，所述USB转换座13以插接的方式与所述Type-C信号传输接口相连接；此时所述USB转换座13的USB信号传输接口作为新的终端连接接口，则USB转换座13的USB信号传输接口可与包含USB信号输出接口的第一终端进行连接，所述USB转换座13信号输出接口连接所述Type-C信号传输接口。通过增加USB转换座13，可进一步扩展信号无线发射器20的使用功能，具体实施方式与图2相同所示。
在更具体的实施例中，所述数据信号传输接口21为高清多媒体信号传输接口；所述信号转换处理器10包括Type-C转换座14及显示信号转换座15，所述Type-C转换座14以插接的方式与所述显示信号转换座15相连接；所述Type-C转换座14包括Type-C信号传输接口141及Type-C控制芯片142；所述Type-C信号传输接口作为所述终端连接接口11，所述Type-C控制芯片142的输入端连接所述Type-C信号传输接口141；所述显示信号转换座15包括显示信号传输接口151及所述转换处理单元12，所述转换处理单元12为显示信号转换芯片，所述显示信号传输接口151连接所述Type-C控制芯片142的输出端，所述显示信号转换芯片152的输入端连接所述显示信号传输接口151、其输出端连接所述高清多媒体信号传输接口，具体实施方式如图4所示。具体的，Type-C控制芯片142用于检测终端连接接口11(此时终端连接接口11为Type-C信号传输接口)是否与第一终端相连接，并可获取第一终端的属性信息并传输至显示信号转换芯片152；Type-C控制芯片142还可对来自第一终端的终端数据信息的类型是否为高清多媒体信号进行判断，并将判断结果传输至所述显示信号转换芯片152，具体的，可通过Type-C控制芯片142与显示信号转换芯片152之间的CC信道传输判断结果；若所述判断结果为是，所述Type-C控制芯片142将所述终端数据信息转换为显示信号后通过第一传输通道传输至所述显示信号转换芯片152，其中，第一传输通道可以是DP-ALT，DP-ALT即为显示信号传输接口(DP接口)151中ALT模式的数据传输通道；若所述判断结果为否，所述Type-C控制芯片通过第二传输通道将所述终端数据信息传输至所述显示信号转换芯片，第二传输通道即为显示信号传输接口151中空闲的针脚(pin)。显示信号转换芯片152用于接收上述判断结果，并根据判断结果对所接收到的显示信号或终端数据信息进行处理，具体的，显示信号转换芯片152接收到的判断结果为是，则将显示信号转换为高清多媒体信号后传输至所述无线发射器20以进行无线发射；显示信号转换芯片152接收到的判断结果为否，将终端数据信息传输至所 述无线发射器20以进行无线发射，可通过高清多媒体信号传输接口151中空闲的针脚(pin)对终端数据信息进行传输。若编码单元22不支持直接对HDMI信号进行编码操作，则还需在信号无线发射器20内设置一个转换处理单元(如前述的A/V转换器)将HDMI信号转换为编码单元所支持的格式类型，之后再将进行转换处理后的信号输出至编码单元22进行编码。
更具体的，所述信号转换处理器10还包括USB转换座13，所述USB转换座13以插接的方式与所述Type-C转换座14相连接；此时所述USB转换座13的USB信号传输接口作为所述终端连接接口11，则USB转换座13的USB信号传输接口可与包含USB信号输出接口的第一终端进行连接，所述USB转换座13信号输出接口连接所述Type-C信号传输接口141。通过增加USB转换座13，可进一步扩展信号无线发射器20的使用功能，具体实施方式如图5所示。
