具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
为便于理解，首先对本申请实施例的应用场景进行简单的介绍。
为了实现远程设备和终端设备之间的视频传输，现有技术一般采用的是在远程设备中同时集成WiFi芯片和2.4GHz无线通信芯片，终端设备与远程设备通过WiFi建立无线连接后，使用专用遥控器发出控制指令，从而使远程设备拍摄并传输视频，随后终端设备可以接收到远程设备传输的视频资源。由于现有技术需要在远程设备上同时集成两种芯片，而且必须配备专用的遥控器，这使其成本较高，而且WiFi协议设计并不考虑功耗问题，导致使用WiFi芯片进行视频传输的功耗 较高，不适合依靠电池供电的远程设备。同时，现有技术在传输过程中，通常将远程设备作为WLAN hotspot，手机通过WiFi与远程设备建立连接，由于手机WiFi通道被占用，使得手机无法连接WiFi路由器接入互联网，造成了使用的不便利，而且由于人机交互界面的限制，远程设备上通常不能进行密码的设置，造成设备连接的不安全。
本申请实施例通过在支持低功耗蓝牙的第一BLE端和第二BLE端之间建立两个连接通道，同时完成视频和遥控指令的传输，解决了现有技术中视频传输存在的成本高、功耗大以及使用不便利的问题。
图1示出了本申请实施例的视频传输的系统架构示意图，如图1所示，支持低功耗蓝牙的第一BLE端110和第二BLE端120，通过建立第一蓝牙通道和第二蓝牙通道同时完成视频和指示信息以及其他遥控指令等的传输。
应理解，本申请实施例的第一BLE端和第二BLE端可以为BLE芯片，或者为包括BLE芯片的设备，第一BLE端可以为远程设备，例如无人机和遥控摄像头等，第二BLE端可以为终端设备，包括但不限于各种形式的移动电话(或称为“蜂窝”电话)、笔记本电脑、平板电脑、具有无线通讯模块的台式计算机，比如还可以包括各种形式的物联网终端，以及各种便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
图2示出了本申请实施例的视频传输方法的示意图。图2所示的方法包括步骤S210和S220，下面对这些步骤进行详细描述。
S210，第二BLE端通过低功耗蓝牙的第一蓝牙通道向第一BLE端发送传输指示信息。
作为一个实施例，所述传输指示信息可以用于所述第一BLE端通过低功耗蓝牙的第二蓝牙通道传输视频。
可选地，本申请实施例的第一蓝牙通道可以为逻辑链路控制和适配层协议通道(Logical Link Control and Adaptation Protocol channel，L2CAP channel)，第二蓝牙通道可以为等时通道(isochronous channel)。
可选地，在第二BLE端通过第一蓝牙通道向第一BLE端发送传输指示信息之前，第一BLE端可以通过低功耗蓝牙进行广播并与第二BLE端建立加密安全连接，并在加密安全连接上建立第一蓝牙通道，然后，第一BLE端和第二BLE端通过第一蓝牙通道传输信息。
可选地，第二BLE端还可以通过第一蓝牙通道向第一BLE端发送拍摄指令， 指示第一BLE端进行拍摄。
可选地，第二BLE端还可以通过第一蓝牙通道向第一BLE端发送运动指令，指示第一BLE端进行移动。
可选地，第一BLE端还可以通过第一蓝牙通道向第二BLE端发送状态信息，状态信息可以包括电池电量和预计续航时间等。
S220，第一BLE端根据所述传输指示信息，通过所述第二蓝牙通道向第二BLE端传输视频。
作为一个实施例，所述传输指示信息可以包括初始最大码率和所述第二蓝牙通道的参数。第一BLE端可以根据上述初始最大码率和第二蓝牙通道的参数，与第二BLE端建立第二蓝牙通道。具体地，第一BLE端通过第二蓝牙通道接收到包括初始最大码率和所述第二蓝牙通道的参数的传输指示信息，第一BLE端将接收到的初始最大码率配置给处理模块，并通知第二BLE端配置完成，随后根据初始最大码率和第二蓝牙通道的参数与第二BLE端建立第二蓝牙通道。可选地，上述第二蓝牙通道参数可以包括视频传输间隔和重传次数。
可选地，上述初始最大码率和第二蓝牙通道的参数可以是第二BLE端在与第一BLE端建立安全连接之后，第二BLE端根据通过第一蓝牙通道获取得到的第一BLE端的发射功率和测量得到的接受信号强度指示(received signal strength indication，RSSI)数据确定的。应理解，因为第一BLE端的发射功率可以不断改变，所以其对应的最大码率也会发生相应的改变。为了实现BLE端的视频传输质量和功耗达到平衡，BLE端可以配置发射功率的上下限，也可以配置发送视频的最大码率上下限。
建立上述第二蓝牙通道后，第一BLE端可以根据初始最大码率通过上述第二蓝牙通道向第二BLE端传输视频，相应的发射功率可以采用初始的发射功率。在视频传输过程中，通道状态可能会实时变化，相应地，在本申请实施例中，还可以进行自适应调整，下面进行具体描述。
可选地，该传输指示信息可以包括调整指示信息，通过调整指示信息指示最大码率和发射功率的改变，可以提高视频传输的自适应能力。
作为一个实施例，该第二BLE端可以在视频的误码率大于或等于第一阈值时发送传输指示信息，指示第一BLE端增大传输视频的发射功率，或者减小传输视频的最大码率。具体地，在第一传输模式(如视频质量优先模式)下，发送传输指示信息，指示第一BLE端增大传输视频的发射功率；若发射功率达到发射功率 上限值，则减小传输视频的最大码率，根据减小后的最大码率与所述第二BLE端重新建立第二蓝牙通道，并通过重新建立的第二蓝牙通道向第二BLE端传输所述视频；或者在第二传输模式(如功耗优先模式)下，发送传输指示信息，指示第一BLE端减小传输视频的最大码率，根据减小后的最大码率与第二BLE端重新建立第二蓝牙通道，并通过重新建立的第二蓝牙通道向第二BLE端传输视频；若最大码率达到最大码率下限值，则增大传输视频的发射功率。
作为另一个实施例，该第二BLE端可以在视频的误码率小于第二阈值时发送传输指示信息，指示第一BLE端增大传输视频的最大码率，或者减小传输视频的发射功率。具体地，在第一传输模式(如视频质量优先模式)下，发送传输指示信息，指示第一BLE端增大传输视频的最大码率，根据增大后的最大码率与第二BLE端重新建立第二蓝牙通道，并通过重新建立的第二蓝牙通道向第二BLE端传输所述视频；若所述最大码率达到最大码率上限值，则减小传输视频的发射功率；或者在第二传输模式(如工作时间或功耗优先模式)下，发送传输指示信息，指示第一BLE端减小传输视频的发射功率；若发射功率达到发射功率下限，则增大传输视频的最大码率，根据增大后的最大码率与所述第二BLE端重新建立第二蓝牙通道，并通过重新建立的第二蓝牙通道向所述第二BLE端传输视频。
应理解，传输视频的质量和设备的功耗与设备的发射功率以及码率相关，其中视频质量与码率有直接关系，设备功耗与发射功率有直接关系，所以在视频质量优先模式下，为了提高视频质量，会优先采用改变发射功率的方法，而在功耗优先模式下，为了尽量减少功耗，提高BLE端的工作时间长度，会优先改变发送码率，工作时间长度也可以理解为续航时间长度，通过在不同的工作模式下选择不同的调整方法，可以实现视频传输质量和BLE端工作时间长度的平衡。第一BLE端可以通过发送状态信息使得第二BLE端获取到第一BLE端工作时间长度，例如，第一BLE端可以通过第一蓝牙通道向第二BLE端发送状态信息，状态信息可以包括电池电量和预计续航时间等。若该电池电量少于预定电池电量或者是预计续航时间少于预定续航时间，则自动选择第二传输模式(如工作时间或功耗优先模式)，另外，也可以由用户根据电池电量和预计续航时间选择第一传输模式还是第二传输模式，以适应用户需求。选择第一传输模式还是第二传输模式可以由系统预设，或者是由用户通过系统界面或者APP设置，本实施例对此不作限定。
上述第一阈值和第二阈值可以为预先设定的误码率阈值，其中第一阈值大于第二阈值。
图3示出了在第一传输模式下，该第一传输模式可以为视频质量优先模式，第二BLE端根据误码率向第一BLE端发送调整指示信息，第一BLE端根据调整指示信息传输视频的具体流程。
如图3所示，在第一传输模式下，第二BLE端计算接收到的视频的误码率，即步骤S310，随后根据计算结果，进入步骤S320，判断视频误码率与第一阈值的关系，若视频误码率大于等于第一阈值，则发送传输指示信息，即S330，第一BLE端在接收到传输指示信息后，进入步骤S3301，判断发射功率是否达到上限，如果没有达到上限，则进入步骤S3302，增加第一BLE端的发射功率，若发射功率已经达到上限，则减小第一BLE端的最大码率，即S3303，并根据减小后的最大码率与第二BLE端重新建立第二蓝牙通道，并通过重新建立的第二蓝牙通道向第二BLE端传输视频。类似地，若第二BLE端计算接收到的视频的误码率小于第一阈值，则继续判断视频误码率是否小于第二阈值，即S340，若是，则发送传输指示信息S350，第一BLE端在接收到第二调整指示信息之后，进入步骤S3501，判断当前最大码率是否达到上限，如果未达到上限，则增大第一BLE端的最大码率，即S3502，并根据增大后的最大码率与第二BLE端重新建立第二蓝牙通道，并通过重新建立的第二蓝牙通道向第二BLE端传输视频；若当前最大码率达到上限，则减小第一BLE端的发射功率，即S3503。
通过上述调整方式，可以保证视频正常传输的同时，获得更高质量的传输视频。
图4示出了在第二传输模式下，该第二传输模式可以为功耗优先或工作时间优先模式，第二BLE端根据误码率向第一BLE端发送调整指示信息，第一BLE端根据调整指示信息传输视频的具体流程。
如图4所示，在第二传输模式下，第二BLE端计算接收到的视频的误码率，即步骤S410，随后根据计算结果，进入步骤S420，判断视频误码率与第一阈值的关系，若视频误码率大于等于第一阈值，则发送传输指示信息，即S430，第一BLE端在接收到传输指示信息后，进入步骤S4301，判断最大误码率是否达到下限，若未达到，则减小最大码率，即S4302，并根据减小后的最大码率与第二BLE端重新建立第二蓝牙通道，并通过重新建立的第二蓝牙通道向第二BLE端传输所述视频；若达到下限，则进入步骤S4303，增大发射功率。类似地，若第二BLE端计算接收到的视频的误码率小于第一阈值，则继续判断视频误码率是否小于第二阈值，即S440，若是，则发送传输指示信息S450，第一BLE端在接收到传输指示 信息之后，进入步骤S4501，判断发射功率是否达到下限，若未达到，则减小发射功率，若达到，则进入步骤S4503，增大最大码率，并根据增大后的最大码率与第二BLE端重新建立第二蓝牙通道，并通过重新建立的第二蓝牙通道向第二BLE端传输视频。
通过上述调整方式，可以保证视频正常传输的同时，降低能耗，提高第一BLE端的工作时长。
因此，本申请提供的技术方案能够降低视频传输的成本，实现视频功耗与质量的平衡并提高使用体验。
