一些公开实施例中，在音视频传输装置10为发送端时，音视频传输装置10用于响应第一操作指令暂停音视频传输。并使与其连接的接收端音视频传输装置10保持输出画面。具体地，响应第一操作指令的发送端音视频传输装置10暂停与其已建立连接的接收端音视频传输装置10的音视频传输，接收端音视频 传输装置10保持第一操作指令生成时刻的输出画面内容。在音视频传输装置10为接收端时，音视频传输装置10响应第一操作指令切换用于进行音视频传输的频点。具体地，用于进行音视频传输的频点为WIFI连接使用的频点。

一些公开实施例中，在音视频传输装置10为发送端时，音视频传输装置10响应第二操作指令，切换与该音视频传输装置10连接的接收端侧的音视频传输装置10的数量。具体地，发送端侧的音视频传输装置10响应第二操作指令，执行广播过程，使得多个接收端的音视频传输装置10接收该音视频传输装置10发送的音视频数据。
一些公开实施例中，在音视频传输装置10为接收端时，音视频传输装置10响应第二操作指令，切换与接收端的音视频传输装置10连接的发送端的音视频传输装置10的状态。其中，切换状态可以是由已连接状态切换为未连接状态，也可以是由未连接状态切换为已连接状态。具体地，接收端音视频传输装置10断开与一个发送端音视频传输装置10的连接，并与另一个发送端音视频传输装置10进行连接。
一些公开实施例中，音视频传输装置10包括指示灯106。指示灯106不同的点亮模式用于指示音视频传输装置10的运行状态。例如，音视频传输装置10的指示灯106为双色指示灯106，可用于呈现三种颜色。例如，可呈现红、绿、橙三种颜色。当然，在其他实施例中，还可使用其他颜色，此处仅为举例。
一些应用场景中，音视频传输装置10处于第一设置模式下时，指示灯106的状态为红、绿交替闪烁。音视频传输装置10处于第二设置模式下时，指示灯106的状态为橙色慢速闪烁。其中，处于第二设置模式下的音视频传输装置10作为WIFI–AP，启动web服务，用户可以使用计算机连接到该WI-FIAP网络，通过浏览器打开内置web网页，对音视频传输装置10的工作参数进行调整。一些应用场景中，音视频传输装置10为发送端时，通过web网页可设置该发送设备的视频应用场景。音视频传输装置10可预先设置若干组可选编码参数，使得音视频传输装置10的若干组编码参数分别对应各种视频应用场景。例如，若干组可以为两组，视频应用场景分为视频模式、演示模式。其中，编码参数包括 关键帧间隔、编码码率以及码率控制方式中的一种或多种。一些应用场景中，音视频传输装置10为接收端时，接收端通过内置web网页可设置该接收端的音视频传输装置10的视频应用场景。视频应用场景有流畅模式及低延迟模式。

在音视频传输装置10处于传输模式下时，指示灯106的状态与音视频传输装置10的实际状态有关。具体地，未建立音视频数据连接时，指示灯106的状态为红色常亮，已建立音视频数据连接但未传输音视频时，指示灯106的状态为橙色常亮或绿色常亮。具体地，在音视频传输装置10为第一传输模式下时，为橙色常亮，在音视频传输装置10为第二传输模式下时，为绿色常亮。正在传输音视频数据时，指示灯106为橙色快速闪烁或绿色快速闪烁。具体地，在音视频传输装置10为第一传输模式下时，为橙色快速闪烁，在音视频传输装置10为第二传输模式下时，为绿色快速闪烁。
上述方案，通过使用公头形式的接口传输音视频使得音视频传输装置10无需使用臃肿的音视频线与音视频源连接，使得音视频传输装置10便于携带，以及提高了音视频传输过程的便捷性。
为更好地理解由发送端和接收端均只有一个音视频传输装置，以及各方具有多个音视频传输装置的情况，请参见图4和图5。图4是本申请音视频传输装置一实施例中示出两个音视频传输装置建立通信连接的示意图，图5是本申请音视频传输装置另一实施例中示出多个音视频传输装置建立通信连接的示意图。
为区分发送端和接收端，本公开实施例中，统一将发送端的音视频传输装置标记为10，接收端的音视频传输装置标记为20。如图4和5所示，发送端只有一个音视频传输装置10，接收端只有一个音视频传输装置20时，音视频传输装置10与音视频传输装置20之间不用路由器连接，而发送端有多个音视频传输装置10，接收端有多个音视频传输装置20时，可以使用路由器连接。并且，每个发送端的音视频传输装置10与一个源设备连接，每个接收端的音视频传输装置20与一个显示设备连接。
本公开实施例提供的音视频传输装置可以用于视频会议、家庭影音、多媒体教学等领域。
请参阅图6，图6是本申请音视频传输方法一实施例的流程示意图。如图6 所示，本公开实施例提供的音视频传输方法可以包括以下步骤：
步骤S11：获取音视频传输装置的预设信息。
其中，本公开实施例提供的音视频传输方法应用于音视频传输装置实施例提供的音视频传输装置。
其中，预设信息为用户提前设置或出厂时设置的信息。其中，用户提前设置预设信息的方式可以是通过音视频传输装置的内置网页确定。并且，通过音视频传输装置的内置网页，可以设置音视频传输装置的传输模式，如上一实施例所述，音视频传输装置的传输模式包括第一传输模式和第二传输模式。其中，第一传输模式和第二传输模式的具体形式请参见音视频传输装置实施例所述，此处不再赘述。
步骤S12：基于预设信息，构建音视频传输装置与其他音视频传输装置的通信连接。
一些公开实施例中，预设信息包括配对码以及至少一个密钥。基于密钥对配对码进行加密，得到第一网络的网络参数。其中，第一网络的网络参数包括网络名称以及网络密码。
一些公开实施例中，密钥包括第一密钥和第二密钥。其中，第一密钥和第二密钥可以相同也可以不同，本公开实施例中，选择第一密钥和第二密钥不同。具体地，第一密钥和第二密钥为预设，且在音视频传输装置出厂时被设定并不可读。
其中，基于密钥对配对码进行加密，得到第一网络的网络参数的方式可以是，使用第一密钥对配对码按照第一预设加密算法得到网络名称。以及使用第二密钥对配对码按照第二预设加密算法得到网络密码。其中，第一预设加密算法和第二预设加密算法可以相同，也可以不同。本公开实施例中，第一预设加密算法和第二预设加密算法可以均为AES加密算法。其中，获取第一网络的网络名称以及网络密码是通过音视频传输装置的通信模块获取。具体地，根据通信模块中的连接参数生成模块获取。
其中，这里的第一网络可以是发送端的音视频传输装置作为网络接入点形成的WIFI网络，也可以是接收端的音视频传输装置作为网络接入点形成的WIFI网络。
进一步地，发送端和接收端的音视频传输装置中的配对码和密钥相同。本公开实施例中，选择将接收端的音视频传输装置作为第一网络的接入点。其中， 接收端和发送端均需要通过配对码和密钥获取第一网络的网络名称和网络密码。
其中，在接收端的音视频传输装置获取到第一网络的网络名称和网络密码之后，进行广播，使得其他音视频传输装置能够搜索到该第一网络，并加入第一网络。具体地，音视频传输装置进行隐藏广播，以及广播第一网络的网络名称，以使其他音视频传输装置搜索第一网络的网络名称并加入第一网络。
其中，在发送端的音视频传输装置获取到第一网络的网络名称和网络密码之后，使用第一网络的网络名称进行搜索，在搜索到第一网络的情况下，利用第一网络的网络密码加入第一网络。
由此，发送端的音视频传输装置和接收端的音视频传输装置建立的通信连接。
一些公开实施例中，预设信息还可以是待加入网络的网络名称和密码、组信息、本音视频传输装置的标识、音视频源表中的一者或多者。一些公开实施例中，发送端的音视频传输装置中包括待加入网络的网络名称和密码、组信息、本音视频传输装置的标识。而在接收端的音视频传输装置中，预设信息包括待加入网络的网络名称和密码、组信息、本音视频传输装置的标识、音视频源表。其中，音视频源表中包括需要接收的音视频数据以及发送各个音视频数据对应的发送端的音视频传输标识。其中，音视频传输装置的标识可以是编号。
一些应用场景中，待加入网络的网络接入点为无线路由器，且发送端和接收端的音视频传输装置均作为待加入网络中的STA。其中，发送端和接收端的音视频传输装置通过搜索待加入网络的网络名称，并使用对应的密码，加入无线路由器的WIFI网络。
每个发送端和接收端的音视频传输装置通过使用组信息以及编码来生成本体在WIFI网络中的IP地址。其中，音视频传输装置的编码取值小于或等于10。本公开实施例中，将发送端的音视频传输装置的IP地址的构成可以是组信息.编号+100。接收端的音视频传输装置的IP地址的构成可以是组信息.编号+120。例如，组信息为192.168.2，发送端和接收端的音视频传输装置的编号均为1，则发送端的音视频传输装置的IP地址为192.168.2.101，而接收端的音视频传输装置的IP地址为192.168.2.121。
由此，各发送端和接收端的音视频传输装置加入了同一无线路由器提供的WIFI网络中。
一些公开实施例中，使用同一组信息的发送端和接收端的音视频传输装置 构成装置集合。其中，一个无线局域网下可以允许存在多个装置集合。其中，每个装置在无线局域网中的IP地址的网络地址部分可以由装置的组信息生成，不同的组信息所生成的网络地址不同。被设置为相同组信息的发送端和接收端的音视频传输装置具有相同的网络地址，进而在各音视频传输装置所属无线局域网中被设置为相同组信息之间的装置才能通过IP地址相互传输信息，由装置的网络协议栈层面保证不同装置集合之间音视频数据相互隔离。其中，一个装置集合中，接收端的音视频传输装置只能请求同一个集合中的发送端音视频传输装置向其发送音视频数据。
步骤S13：利用通信连接进行与其他音视频传输装置之间的音视频传输。
一些公开实施例中，若发送端和接收端均只有一个音视频传输装置时，发送端的音视频传输装置通过TCP方式向接收端发送音视频数据，并由接收端的音视频传输装置接收并解码输出至显示设备。具体地，发送端与源设备连接，接收端与显示设备连接。源设备输出的音视频信号被发送端采集、压缩并编码为待传输的音视频数据，然后通过发送端与接收端之间建立的WIFI连接传输到接收端，再经过接收端的解码并最终输出到显示设备进行播放。
一些公开实施例中，在发送端和接收端中的至少一端存在两个及以上的音视频传输装置时，接收端的音视频传输装置向其中一个发送端的音视频传输装置发送音视频请求，发送端的音视频传输装置响应接收端的音视频传输装置发送的音视频请求，向接收端的音视频传输装置发送对应的音视频。如上述，接收端的音视频传输装置中包括音视频源表。其中，音视频源表中包括待传输的音视频数据对应的音视频传输装置的标识。一些应用场景中，音视频源表可以认为是发送端音视频传输装置的编号集合。接收端的音视频传输装置可以向音视频源表中的任意一个音视频传输装置发送音视频请求。一些应用场景中，在接收完当前的音视频数据之后，断开与当前的音视频数据对应的音视频传输装置之间的通信连接。其中，本公开实施例所述的通信连接可以认为是数据连接。然后构建于待传输的音视频数据对应的音视频传输装置之间的通信连接。
一些公开实施例中，在发送端和接收端中的至少一端存在两个及以上的音视频传输装置时，可以认为是音视频传输装置处于第二传输模式。
若发送端的音视频传输装置中的操作键基于用户的短按操作产生第二操作指令时，则该音视频传输装置响应第二操作指令，切换与本音视频传输装置连接的其他音视频传输装置的数量。具体地，音视频传输装置根据组信息，生成 所有的接收端的音视频传输装置的IP地址，并通过UDP方式向这些IP地址发送源广播请求信令，其中，源广播请求信令中包含本音视频传输装置的编号。由此，在接收端的音视频传输装置接收到源广播请求信令后，响应该源广播请求信令。具体地，取出源广播信令对应发送端的音视频传输装置的IP地址，并保存。判断源广播请求信令所包含的音视频传输装置的编号是否包括在本音视频传输装置中的音视频源表中，若是，则响应该源广播请求信令，并向该发送端的音视频传输装置发送音视频请求，以获取对应的音视频。若判断结果为否，则结束关于源广播请求信令的处理。一些公开实施例中，该信令发送的过程为单向，且无需等待任何接收端的音视频传输装置的响应及应答。也就是说，接收端的音视频传输装置在接收到该信令之后，无需向发送端的音视频传输装置发送用于表示已收到该信令的答复信令，而发送端的音视频传输装置也无需等待广播请求信令的应答。
若接收端的音视频传输装置中的操作键基于用户的短按操作产生第二操作指令时，则该音视频传输装置响应第二操作指令，切换与本音视频传输装置连接的其他音视频传输装置的状态。具体地，接收端的音视频传输装置从音视频源表中读取当前正在解码的音视频对应的表项的下一个表项，并将该下一个表项作为待连接的发送端的音视频传输装置的编号。然后，断开与当前正在解码的发送端音视频传输装置的音视频连接，并基于待传输音视频对应的音视频传输装置编号，得到对应的IP地址。并向该IP地址发送音视频请求，以获取对应的音视频。最后，将接收到的音视频进行解码输出至显示设备，在音视频传输装置的输出画面上通过OSD显示新的发送端音视频传输装置的编号，并在预设时间段后关闭OSD显示。其中，预设时间段可以自行设置，本公开实施例选择将预设时间段设置为10秒。
一些公开实施例中，音视频传输装置为发送端时，利用通信连接进行与其他音视频传输装置之间的音视频传输的方式还可包括：获取待传输的音视频以及编码参数。其中，编码参数包括编码帧率、编码码率、码率控制方式、关键帧间隔中的一者或多者。其中，编码参数可在音视频传输装置位于第二模式下，自行设置。具体设置方式可以是通过实验方式取得运动画面偏重的视频、清晰度偏重的视频画面的最优参数值并保存。基于用户的调整指令，选择对应的编码参数应用于媒体编码处理模块10221的编码过程中。
然后，按照编码参数对音视频数据进行编码。其中，本公开实施例中优选 H265编码方式对采集到的视频进行压缩并编码，对采集到的音频采用AAC压缩编码。再将编码之后的音视频数据发送至与音视频传输装置具备通信连接的其他音视频传输装置。
一些公开实施例中，音视频传输装置为接收端时，利用通信连接进行与其他音视频传输装置之间的音视频传输的方式还可包括：获取已编码的音视频数据以及解码模式。其中，解码模式包括流畅模式和低延迟模式。其中，流畅模式和低延迟模式对应的解码方式不同，具体地，不同解码模式下接收端的提供音视频编码接收缓冲的深度不同。
不同的应用场景中，使用者对所观察的视频图像质量有不同的偏重，例如在播放视频节目时使用者更关注视频的流畅性，但在静止画面偏重的PPT演示或图片展示时使用者更偏重于画面清晰度。因此，通过发送端的音视频传输装置设置有不同的编码参数，使得用户可以根据具体需求，选择合适的编码参数，从而提高各场景中音视频传输方法的适用度。以及，在接收端的音视频传输装置中设置不同的解码模式，同样能够提高各场景中音视频传输方法的适用度。
上述方案，因为音视频传输装置实施例提供的音视频传输装置使用公头形式的接口传输音视频，无需经过臃肿的音视频线传输音视频，从而提高了音视频传输过程中的便捷性。
