具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1示出了本发明一实施例提供的一种音视频信息的输入方法的流程示意图，如图1所示，该方法包括如下步骤：
S101：第一终端进行视频通话时，启动所述第一终端的中继服务，并获取所述中继服务的地址；
其中，第一终端一般是指自身不包括摄像头和麦克风的终端，如网络电视、笔记本电脑等；用户设备一般指具有摄像头和麦克风的移动终端，例如 智能手机、个人数码助理(PDA)、平板电脑、笔记本电脑等等。本实施例中的第一终端以网络电视为例，用户设备以移动终端(如手机)为例进行说明。中继服务可用于实现音视频数据的中转。例如，可采用第一终端中的网页实时通信中继服务webrtc relay server来进行音视频数据的中转。
举例来说，当通过网络电视进行视频通话时，启动网络电视的网页实时通信中继服务webrtc relay server，并获取该服务的内网地址，如192.168.0.111:888。
S102：根据所述地址生成二维码，以使用户设备根据所述二维码中的地址启动浏览器以采集音视频信息；
举例来说，将webrtc relay server的地址转化为二维码，并在终端上显示。而用户设备扫描该二维码后，则根据webrtc relay server的地址打开浏览器，而webrtc relay server将和用户设备的浏览器建立网页实时通信(Web Real-time Communication，简称webrtc)连接，而用户设备采集的音视频数据均通过该webrtc连接进行传输。其中，webrtc(Web Real-Time Communication，网页实时通信)是一项在浏览器内部进行实时数据、视频和音频通信的技术。
进一步地，浏览器若允许使用用户设备的摄像头和麦克风，则通过浏览器可采集用户的音频和视频数据，并将音频和视频数据通过webrtc连接传输至终端。如此，第一终端与用户设备的连接无需通过蓝牙等设备，只需两者处于同一个子网中即可通过webrtc连接。
S103：接收所述用户设备发送的音视频信息，并将所述音视频信息发送至远端的第二终端。
具体来说，终端通过中继服务，如webrtc relay server接收用户设备发送的音视频信息，并将音视频信息转发至远端的终端。此处，远端的第二终端即为与第一终端进行视频通话的终端。由此可见，本实施可通过webrtc relay server实现音视频信息的转发。
需要说明的是，本实施例中，用户设备作为第一终端的音视频输入设备使用，而远端的第二终端的音视频输出仍采用第二终端自身的屏幕和喇叭设备。
由此可见，本实施例提供了一种音视频信息的输入方法，通过将用户设备作为第一终端上的视频和音频输入设备，基于中继服务技术实现用户设备 与第一终端之间音视频信息的传输，则无需购买单独外设，能够有效节约使用成本；而且，由于用户设备(如手机)的内置摄像头和麦克风的品质较高，后置摄像头的像素远比外置的普通摄像头的像素高，麦克风的音频采集质量也远高于普通麦克风，则视频分辨率及语音效果都能够满足用户需求。
具体来说，上述步骤S103中接收所述用户设备发送的音视频信息，并将所述音视频信息发送至远端的第二终端，具体包括如下子步骤：
A01：通过所述中继服务接收所述用户设备发送的音视频信息。
举例来说，可通过所述webrtc relay server根据webrtc协议接收所述用户设备发送的音视频信息。webrtc relay server将和用户设备的浏览器建立webrtc连接，则基于webrtc协议，第一终端通过webrtc relay server接收用户设备发送的音频和视频数据。
A02：通过所述中继服务将所述音视频信息发送至所述视频通话中的远端的第二终端。
例如，通过webrtc relay server将所述音视频信息发送至所述视频通话中的远端的第二终端。
由此可见，本实施例中进行音视频输入时，第一终端只是作为数据中继服务存在，即将用户设备传来的视频和语音数据转发给视频通话中的第二终端。
图2示出了本发明另一实施例提供的一种音视频信息的输入方法的流程示意图，如图2所示，该方法包括如下步骤：
S201：用户设备扫描第一终端上显示的二维码时，开启所述用户设备的浏览器；所述二维码包括所述第一终端的中继服务的地址。
具体来说，用户设备通过扫描第一终端上显示的二维码，获得第一终端的中继服务的地址，如webrtc relay server的地址，进一步通过浏览器打开所述地址，使得第一终端通过webrtc relay server与用户设备的浏览器建立webrtc连接。
S202：通过所述浏览器采集所述用户设备的音视频信息。
具体来说，使用浏览器内置的中继服务组件采集用户设备的音视频信息。例如进一步使用浏览器内置的webrtc组件，采集所述用户设备的摄像头和麦克风的数据，以获得音视频信息。
S203：根据所述中继服务的地址，将所述音视频信息发送至所述第一终端。
具体来说，步骤S203中的根据所述中继服务地址，将所述音视频信息发送至所述第一终端，具体包括如下子步骤：
B01：根据中继服务的地址，建立所述第一终端与所述用户设备浏览器的连接；
例如，根据webrtc relay server的地址，建立第一终端与用户设备浏览器之间的webrtc连接。
B02：基于所述连接，通过所述浏览器将所述音视频信息发送至所述第一终端的中继服务，以使所述中继服务将所述音视频信息发送至远端的地第二终端。
进一步地，基于所述webrtc连接，通过所述浏览器将所述音视频信息发送至所述第一终端的webrtc relay server，以使所述webrtc relay server将所述音视频信息发送至远端的地第二终端
具体来说，WebRTC由三个部分组成：媒体流MediaStream，包括来自本地的音频视频流，或者来自远端浏览器的音频视频流；对等连接PeerConnection，用于执行音频视频调用，支持加密和带宽控制；数据通道DataChannel，采用点对点传输，用来传输常规数据。
则相应地，步骤B02中，通过所述浏览器将所述音视频信息发送至所述第一终端的中继服务具体实现过程可为：所述浏览器通过DataChannel将音视频信息发送至第一终端的webrtc relay server。
由此可见，本实施例中，当第一终端和第二终端进行视频通话时，将用户设备作为第一终端的音视频信息输入设备，而且，用户设备通过摄像头和麦克风采集音视频信息时，只需使用用户设备的浏览器实现对麦克风和摄像头的控制及音视频数据的采集，无需安装额外的应用程序app(Application)，如此，使得音视频信息的输入方法更为简便快捷，节省了软件开发等人力成本。
需要说明的是，步骤S202之前，该方法还包括如下步骤：
根据用户指令，允许所述浏览器使用所述用户设备的摄像头和麦克风。
相应地，根据用户指令，也可禁止所述浏览器使用所述用户设备的摄像 头和麦克风。
由此可见，在采用浏览器采集所述用户设备的音视频信息之前，还需要用户允许所述浏览器使用该用户设备的摄像头和麦克风，增加了用户设备使用时的安全性，防止私人信息被泄露。
为了更清楚地说明本发明的技术方案，下面通过一个具体的实施例来说明音视频信息的输入方法。本实施例中以网络电视和手机的交互为例，网络电视即为上述实施例中的第一终端，手机即为上述实施中的用户设备。如图3所示的音视频信息的输入方法的示意图。
如图3所示，网络电视与远端终端进行时，通过手机作为本地视频的音视频输入设备。
具体来说，网络电视开启视频通话app时，启动电视的webrtc relay server，该服务将使用内网地址如192.168.0.111:8888。Webrtc relay server将和手机浏览器建立webrtc链接(即peerconnect)，手机的音视频数据都会通过peerconnect传输。
进一步地，将上述内网地址转化为二维码，显示在电视屏幕上，待手机扫描后访问。手机扫描二维码后，根据内网地址开启浏览器，并通过浏览器使用其摄像头和麦克风，通过摄像头获得视频数据，通过麦克风获得音频数据，并将所述视频数据和音频数据发送至网络电视。
进一步地，网络电视中的Webrtc relay server通过webrtc协议接收手机浏览器发来的音视频数据流，以在网络电视的本地视频中显示音视频信息；同时，Webrtc relay server将上述音视频流转发给视频通话中的远端方，且该转发是单向的。
由此可见，本实施例中通过将手机作为网络电视上的视频和音频输入设备，基于webrtc技术实现手机与网络电视之间音视频信息的传输，能够有效节约使用成本，且由于手机的视频分辨率及语音效果均较高，都能够满足用户需求。
图4示出了本发明一实施例提供的一种音视频信息的输入装置的结构示意图，如图4所示，该装置包括：服务启动单元401、二维码生成单元402及信息转发单元403。其中：
服务启动单元401，用于当终端进行视频通话时，启动所述终端的中继 服务，并获取所述中继服务的地址；
二维码生成单元402，用于根据所述地址生成二维码，以使用户设备根据所述二维码中的地址启动浏览器以采集音视频信息；
