具体实施方式
在本申请实施例的描述中，“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“例如”等词旨在以具体方式呈现相关概念。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请中的技术领域的技术人员通常理解的含义相同。本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。应理解，本申请中除非另有说明，“多个”是指两个或多于两个。
现有技术提供一种基于遥控设备的投屏控制方法，可应用于一种基于遥控设备的投屏控制系统。投屏控制系统包括遥控设备、投屏设备(例如手机等)和显示设备(例如电视等)。投屏设备用于为显示设备提供投屏内容。显示设备用于显示投屏内容。现有技术提供的投屏控制方法需要遥控设备向显示设备发送指令，显示设备转换指令和投屏设备接收转换后的指令。具体地，在现有的投屏控制方法中，如图1所示，遥控设备11会先向显示设备12发送控制指令，接着显示设备12在应用层将遥控设备11的控制指令转换为投屏设备13的反控指令，并在应用层建立额外的应用层通道来传送转换后的反控指令，然后投屏设备13接收所述显示设备12传送的反控指令，并根据反控指令控制投屏文件，例如幻灯片的翻页、视频的播放和暂停、显示界面的切换、应用程序的打开和关闭等。但是，这需要显示设备12在应用层中转换指令，并需要在应用层中建立应用层通道来中转指令，如此将会导致遥控设备11和投屏设备13之间的信息交互复杂，且会为指令的传送增加额外的时间开销，导致指令时延较大，使得遥控设备11和投屏设备13之间信息的交互不及时。有鉴于此，本申请实施例提出了一种控制设备切换方法，在遥控设备想要控制投屏设备时，无需由显示设备进行指令的转换和中转，遥控设备可以方便地由直接控制显示设备切换为直接控制投屏设备，使得遥控设备可便捷地、简单地和安全地对投屏设备进行控制。
参考图2，为本申请实施例提供的控制设备切换系统的示意图。如图2所示，所述控制设备切换系统20包括显示设备21、遥控设备22及投屏设备23。显示设备21的数量可为一个或多个。显示设备21例如可为手机、平板电脑、数码相机、个人数字助理(personal digital assistant，PDA)、可穿戴设备、膝上型计算机(laptop)、智能电视、大屏、智慧屏、显示器等具有显示屏幕的设备。遥控设备22例如可为遥控器、手机、平板电脑、个人数字助理(personal digital assistant，PDA)、可穿戴设备、膝上型计算机(laptop)等设备。投屏设备23的数量可为一个或多个。投屏设备23例如可为手机、平板电脑、数码相机、个人数字助理(personal digital  assistant，PDA)、可穿戴设备、膝上型计算机(laptop)等设备。
图2中仅示出了一个显示设备21和一个投屏设备23，但是可理解的是，显示设备21的数量也可为多个，或者投屏设备23的数量也可为多个。遥控设备22可通过蓝牙GATT(Generic Attribute Profile，通用属性配置文件)连接将信号发送到所述显示设备21来控制显示设备21。可理解，遥控设备22还可通过其他方式将信号发送到显示设备21来控制显示设备21，例如红外线遥控、wifi等，本申请对此不作限制。
投屏设备23可与显示设备21建立投屏连接来将投屏设备23上的视频、音频及文档等文件投屏到显示设备21上进行显示。遥控设备22可将控制指令发送给显示设备21，显示设备21可响应接收到的控制指令。在一种可能的实现方式中，显示设备21、遥控设备22及投屏设备23可进行组网，建立Mesh网络，通过该Mesh网络进行通信。在另一些可能的实现方式中，显示设备21、遥控设备22及投屏设备23也可通过以其他形式进行组网所形成的网络进行通信，本申请实施例对此不做限定。在一些实施例中，在显示设备21与遥控设备22建立通信连接后，显示设备21可配置遥控设备22发布的消息被显示设备21处理，使得遥控设备22首先为直接控制显示设备21。在显示设备21、遥控设备22及投屏设备23组网后，遥控设备22可接收用户的操作，产生控制设备切换请求，并将控制设备切换请求传送至显示设备21。显示设备21可根据控制设备切换请求显示选择界面以供用户操作遥控设备22选择用户想要将控制转移到的目标控制设备。例如，显示设备21根据对遥控设备22的选择操作，确定目标控制设备为投屏设备23，显示设备21可以据此配置遥控设备22发布的消息被投屏设备23处理。从而，遥控设备22可从直接控制显示设备21切换至直接控制投屏设备23，无需由显示设备21进行控制指令的转换和中转。其中，图2中的遥控设备22与显示设备21之间的实线表示遥控设备22可直接控制显示设备21，遥控设备22与投屏设备23之间的虚线表示遥控设备22可从直接控制显示设备21被切换至直接控制投屏设备23，此时遥控设备22将不再控制显示设备21。可理解的是，遥控设备22还可从直接控制投屏设备23切换至直接控制显示设备21。

在本申请实施例提供的控制设备切换方法的一种实现方式中，显示设备、投屏设备和遥控设备可以通过Mesh网络来实现该控制设备切换方法。为了更好地理解本申请，下面先对Mesh网络所涉及的一些术语和概念进行介绍。但应理解，本申请实施例提供的控制设备切换方法不限定于通过Mesh网络来实现，其他的实现方式(例如通过WiFi网络)也不超出本申请实施例或本申请权利要求书覆盖的范围。
Mesh网络：是一种无线局域网类型，也就是网状结构网络。Mesh网络中的每两个设备之间都可以进行通信。
配网设备：是Mesh网络的节点，可将未配网设备转换为节点。具体的，配网设备可对未配网设备启动配网以将未配网设备加入Mesh网成为Mesh网的节点。在将未配网设备加入Mesh网时，配网设备还会为每个加入Mesh网的设备分发单播地址，因此，在经过配网过程后，每个Mesh网的节点会被分发单播地址。
配置设备：是Mesh网络的节点，可负责配置Mesh网络中的节点。具体的，配置设备还可配置节点的目的地址和/或节点订阅的地址，使得节点之间也可以相互通信。配置设备也可将地址从节点的订阅列表中删除，使得节点之间不可以相互通信。配置设备可与配网设备为同一设备。配置设备也可与配网设备不为同一设备。
地址：可包括单播地址和/或组播地址。每个设备在配网的过程中会被分配唯一的单播地址，该单播地址用于唯一地标识所述设备在所述Mesh网络中的地址。每个组播地址表示逻辑上的一个群组。如果Mesh网中的一个节点的目的地址为另一个节点的单播地址，则所述一个节点发布的消息只能被单播地址为目的地址的另一节点所处理。例如，如果节点A的目的地址为节点B的单播地址，则节点A发布的消息只能被节点B所处理，而不能被其他节点处理，因为其他节点的单播地址不是节点A的目的地址(即节点B的单播地址)。如果Mesh网中的一个节点的目的地址为组播地址，则所述节点发布的消息可以被订阅了组播地址的其他节点所处理，而不能被没有订阅组播地址的其他节点所处理。
发布/订阅：Mesh网可使用发布/订阅模型来进行消息的传输。生成消息的节点会发布消息。需要接收消息的节点可订阅需要的组播地址。消息可被发布至单播地址或组播地址。将生成消息的节点的目的地址配置为单播地址，从而生成消息的节点发布的消息可以被单播地址对应的节点接收。将生成消息的节点的目的地址配置为组播地址，并将该组播地址添加到 需要接收消息的多个节点的订阅列表中，使得需要接收组播消息的多个节点均订阅该组播地址，从而生成消息的节点发布的消息可以被订阅了组播地址的多个节点接收。

S611：投屏设备存储显示设备分发的投屏设备的单播地址。
在一些实施例中，投屏设备的单播地址可唯一地标识Mesh网络中的投屏设备。从而，投屏设备的单播地址可使得Mesh网络中的其他节点识别出来是投屏设备在发布消息。
S612：显示设备配置投屏设备发布消息时的目的地址为显示设备的单播地址。
在一些实施例中，显示设备可以通过Config Model Publication Set配置投屏设备发布消息时的目的地址为显示设备的单播地址。具体的，显示设备可通过Config Model Publication Set发送显示设备的单播地址给投屏设备，投屏设备可将投屏设备发布消息时的目的地址设为显示设备的单播地址。从而，在Mesh网络中，对于投屏设备所发布的消息，显示设备可进行处理。

在一些实施例中，显示设备可以显示一用于触发控制设备切换功能的控件、图标或按钮，当遥控焦点位于该控件、图标或按钮上时，用户可以按下遥控设备上的“确认”键，产生控制设备切换请求。也就是说，所述按键可以是遥控设备上的“确认”键，按下“确认”键产生的确认指令此时可以理解为控制设备切换请求，显示设备在接收到确认指令即控制设备切换请求(步骤S614)后，可显示控制设备选择界面(步骤S615)。
S614：遥控设备向显示设备发送控制设备切换请求，相应地，显示设备接收遥控设备发送的控制设备切换请求。
由于在步骤S606中，显示设备已经配置遥控设备发布消息时的目的地址为显示设备的单播地址，则遥控设备发布的控制设备切换请求，只能被显示设备所处理。
例如，遥控设备发送一条包含控制设备切换请求和遥控设备的目的地址的消息，由于该消息中携带的遥控设备的目的地址为显示设备的单播地址，因此当显示设备接收到该消息后，可根据该消息中的目的地址是显示设备的单播地址，确定要处理这条消息。其他设备(例如投屏设备)即使接收到该消息，也不能正确处理或者不会去处理该消息。
S615：显示设备根据控制设备切换请求显示控制设备选择界面。

S617：遥控设备向显示设备发送焦点转移指令，相应地，显示设备接收遥控设备发送的焦点转移指令。
由于在步骤S606中，显示设备已经配置遥控设备发布消息时的目的地址为显示设备的单播地址，则遥控设备发布的焦点转移指令，只能被显示设备所处理。
S618：显示设备根据焦点转移指令转移焦点的位置至投屏设备。
在一些实施例中，显示设备根据焦点转移指令可知道遥控设备发布的指令为：要求设备将当前焦点向左移动，则显示设备会获取当前焦点的位置，根据当前焦点的位置和将当前焦点向左移动的指令转移焦点的位置。例如，在图8A中，当前焦点位于显示设备的图标802上，则显示设备可根据当前焦点位于显示设备的图标802上和将当前焦点向左移动的指令将焦点转移到投屏设备的图标，使得转移后的当前焦点位于投屏设备的图标803，如图8B所示。
S619：遥控设备响应于作用在遥控设备上的按键的第三操作，产生选定目标控制设备指令。
在一些实施例中，所述选定目标控制设备指令承载在第三操作对应的遥控设备的按键信息中。
在一些实施例中，用户在看到显示设备上的当前焦点转移到投屏设备的图标后，可以通过遥控设备选择投屏设备作为目标控制设备。例如，用户看见如图8B所示的当前焦点转移到投屏设备的图标803后，可按下遥控设备上的确认键来选择投屏设备作为目标控制设备。则，遥控设备接收用户按压确认键的操作，并响应于按压确认键的操作产生选定目标控制设备指令，所述选定目标控制设备指令承载在遥控设备的确认键信息(或者说确认指令)中。
S620：遥控设备向显示设备发送选定目标控制设备指令，相应地，显示设备接收遥控设备发送的选定目标控制设备指令。
由于在步骤S606中，显示设备已经配置遥控设备发布消息时的目的地址为显示设备的单播地址，则遥控设备发布的选定目标控制设备指令，只能被显示设备所处理。
S621：显示设备根据选定目标控制设备指令确定目标控制设备为投屏设备。
在一些实施例中，显示设备根据选定目标控制设备指令可知道遥控设备发布的指令为：要求设备选择当前焦点位置的设备，则显示设备会获取当前焦点的位置，根据当前焦点的位置和选择当前焦点位置的设备的指令选定目标控制设备。例如，在图8B中，当前焦点位于投屏设备的图标803上，则电子设备可根据当前焦点位于投屏设备的图标803上和选择当前 焦点位置的设备的指令选定投屏设备作为目标控制设备。
S622：显示设备根据确定的投屏设备配置遥控设备发布消息时的目的地址为投屏设备的单播地址。
在一些实施例中，显示设备通过Config Model Publication Set发送投屏设备的单播地址给遥控设备，遥控设备将遥控设备发布消息时的目的地址设为投屏设备的单播地址。从而，遥控设备发布的消息只能被投屏设备所处理，其他设备即使接收到遥控设备发布的消息，也不能正确处理遥控设备发布的消息。即，遥控设备可直接控制投屏设备。从而，遥控设备从控制显示设备切换至控制投屏设备。
可以理解的是，遥控设备在从控制显示设备切换至控制投屏设备后，用户可能希望遥控设备从控制投屏设备切换至控制显示设备，下面简单介绍遥控设备从控制投屏设备切换至控制显示设备：
遥控设备可如同上述步骤S613的过程，接收用户的切换控制设备的操作产生控制设备切换请求。由于遥控设备此时控制投屏设备，显示设备无法处理遥控设备发布的控制设备切换请求，因此，需要投屏设备将控制设备切换请求进行中转。在一些实施例中，可预先设置投屏设备接收到控制设备切换请求后重新发布所述控制设备切换请求。由于遥控设备此时控制投屏设备，投屏设备可处理遥控设备发布的控制设备切换请求。由于已经预先设置投屏设备接收到控制设备切换请求后会重新发布，则投屏设备在接收到遥控设备发布的控制设备切换请求后，对控制设备切换请求进行重新发布处理。显示设备接收到投屏设备重新发布的控制设备切换请求后，显示设备可通过如同上述步骤S615的过程，根据控制设备切换请求显示控制设备选择界面。用户看到控制设备选择界面后，可以选择显示设备作为目标控制设备。具体地，在一些实施例中，遥控设备可通过类似上述步骤S616和S619的过程，接收用户的操作，并响应于用户的操作产生转移焦点指令，并还可通过类似上述步骤S619的过程，接收用户的操作，并响应于用户的操作产生选定目标控制设备指令；显示设备可通过类似上述步骤S617-S618的过程，接收焦点转移指令，并根据焦点转移指令转移焦点的位置至显示设备，并还可通过类似上述步骤S620-S621的过程，接收选定目标控制设备指令，根据当前焦点的位置和选定目标控制设备指令确定目标控制设备为显示设备。进而，在选择显示设备作为目标控制设备之后，显示设备可通过如同上述步骤S606的过程，配置遥控设备发布消息时的目的地址为显示设备的单播地址，从而将遥控设备从直接控制投屏设备切换回直接控制显示设备。
可以理解的是，在遥控设备从控制投屏设备切换至控制显示设备，还可根据需要，重新按照上述的切换控制设备操作从控制显示设备切换至控制投屏设备，本申请对此不作限制。也就是说，本申请实施例提供的控制设备切换方法，可实现控制设备(即，遥控设备直接控制的设备)的来回、多次切换。
可以理解的是，上述的步骤S612的顺序可在步骤S622之后，本申请对此不作限制。
可以理解的是，在一些实施例中，在遥控设备控制投屏设备时，在显示设备接收到投屏设备重新发布的控制设备切换请求后，也可省略配置遥控设备发布消息时的目的地址为显示设备的单播地址的操作，继续由投屏设备对遥控设备发布的消息进行中转(或重新发布)，直至显示设备完成配置遥控设备的目的地址来使得遥控设备直接控制显示设备或者投屏设备，或者，显示设备接收到退出配置的操作等。
可以理解的是，步骤S601-S606和步骤S607-S612可以互换顺序，或者步骤S601-S606和步骤S607-S612可以同时执行，本申请对此不作限制。
可以理解的是，图6中的步骤S613-S614可省略，用户可通过操作显示设备产生控制设备切换请求，例如显示设备包括一个用于触发产生控制设备切换请求的切换键或者组合按键，或者显示设备上显示有一个用于触发产生控制设备切换请求的虚拟按键，或者显示设备的菜单中显示有用于触发产生控制设备切换请求的项目等，本申请对此不作限制。
可以理解的是，图6中的步骤S615-S620可省略，在一些实施例中，所述遥控设备可为手机等电子设备，遥控设备上可安装有应用程序(APP)来模拟遥控器的功能。显示设备还可根据控制设备切换请求产生控制设备选择界面信息，并发布所述控制设备选择界面信息。遥控设备可接收所述控制设备选择界面信息，若遥控设备为例如手机等具有显示屏的电子设备，则遥控设备可以根据所述控制设备选择界面信息，显示控制设备选择界面。遥控设备还可接收用户在控制设备选择界面中选择投屏设备的操作，并响应于选择投屏设备的操作确定目标控制设备为投屏设备，并发送包括目标控制设备为投屏设备的选定目标控制设备指令至显示设备。进而显示设备可以将遥控设备发布消息时的目的地址配置为投屏设备的单播地址，使得接下来遥控设备发布的控制指令能直接发送至投屏设备，遥控设备切换为直接控制投屏设备。
可以理解的是，显示设备还可显示显示设备扫描发现的设备列表，以供用户从中选择设备来加入Mesh网络中，例如选择遥控设备和投屏设备加入Mesh网络中，本申请对此不作限制。
可以理解的是，图6中的步骤S601可省略，遥控设备在上电时以广播的方式发送第一入网申请；图6中的步骤S607可省略，投屏设备在上电时以广播的方式发送第二入网申请，本申请对此不作限制。
可以理解的是，图6中的步骤S615-S621可省略，显示设备可根据当前控制显示设备和控制设备切换请求确定目标控制设备为投屏设备，本申请对此不作限制。也就是说，显示设备可不显示供用户选择目标控制设备的界面，显示设备在步骤S614接收到遥控设备发送的控制设备切换请求后，就直接响应于所述控制设备切换请求，配置遥控设备发布消息时的目的地址为投屏设备的单播地址。类似地，若用户想要使遥控设备从直接控制投屏设备切换回直接控制显示设备，则用户可以对遥控设备的按键执行第一操作，所述第一操作触发遥控设备向投屏设备发布控制设备切换请求，投屏设备将接收到的控制设备切换请求重新发布至显示设备，从而显示设备就直接响应于所述控制设备切换请求，配置遥控设备发布消息时的目的地址为显示设备的单播地址。
可以理解的是，图6中的步骤S616-S618可省略，用户可直接选择当前焦点位置的设备，无需进行焦点转移，本申请对此不作限制。
图6所示的控制设备切换方法不仅可应用于一投一的场景，还可应用于多投一的场景。在多投一的场景下，如图9所示，多个投屏设备901(例如包括投屏设备904、投屏设备905、投屏设备906)将音频、视频、文档等投屏到一个显示设备902上分屏显示，一个显示设备902配有一个遥控设备903。在多投一的场景下，显示设备902可作为配网设备和配置设备。显示设备902可作为配网设备将遥控设备903和多个投屏设备901加入Mesh网络中。显示设备902还可作为配置设备配置投屏设备901发布消息的目的地址，并配置遥控设备903发 布消息的目的地址和投屏设备901订阅的地址。
在多投一的场景下，显示设备902作为配网设备将遥控设备903和多个投屏设备901加入Mesh网络中的过程与图6中的在一投一的场景下显示设备作为配网设备将遥控设备和投屏设备加入Mesh网络中的过程相似；显示设备902作为配置设备配置多个投屏设备901发布消息的目的地址的过程与图6中的一投一的场景下显示设备作为配置设备配置投屏设备发布消息的目的地址的过程相似；显示设备902作为配置设备配置遥控设备903发布消息的目的地址为显示设备的单播地址的过程与图6中的一投一的场景下显示设备作为配置设备配置遥控设备发布消息的目的地址为显示设备的单播地址的过程相似，在此不再赘述。
在多投一的场景下，遥控设备903从控制多个投屏设备901和显示设备902中的一个设备切换至控制另一设备的过程与图6中的一投一的场景下遥控设备903在控制投屏设备901和控制显示设备902之间进行切换的过程相似，在此不再赘述。
在多投一的场景下的控制设备切换方法，与上述一投一的场景下的控制设备切换方法的不同之处在于：
显示设备作为配置设备，若为遥控设备从控制多个投屏设备和显示设备中的一个设备切换至控制多个投屏设备的情形，则显示设备可确定目标控制设备为多个投屏设备。显示设备还专门分配目的组播地址，配置遥控设备发布消息时的目的地址为所述目的组播地址，并配置被直接控制的多个投屏设备订阅的地址为所述目的组播地址。
在一些实施例中，所述被直接控制的多个投屏设备为逻辑上的一个群组。所述显示设备可从组播地址[OxC000,OxFEEE]中为所述群组专门分配目的组播地址。所述显示设备可通过Config Model Publication Set配置遥控设备发布消息时的目的地址为所述目的组播地址，并通过Config Model Subscription Add配置群组中要被直接控制的多个投屏设备订阅的地址为所述目的组播地址。具体的，显示设备可通过Config Model Publication Set发送目的组播地址给遥控设备，遥控设备将遥控设备发布消息时的目的地址设为目的组播地址；显示设备还可通过Config Model Subscription Add发送目的组播地址给用户选择的要进行控制的多个投屏设备，每个选择的投屏设备都在自己的订阅列表中添加目的组播地址。从而，遥控设备可被切换至控制多个投屏设备。
例如，如图9所示，多个投屏设备901分别为第一投屏设备904、第二投屏设备905和第三投屏设备906。若为遥控设备903从控制显示设备902切换至控制第二投屏设备905和第三投屏设备906的情形，遥控设备903和显示设备902可如图6中步骤S613-步骤S620的过程进行信号的产生和信息的交互，然后，显示设备902根据选定目标控制设备指令确定目标控制设备为第二投屏设备905和第三投屏设备906。则第二投屏设备905和第三投屏设备906为逻辑上的一个群组。接着，显示设备902为所述群组专门分配目的组播地址OxC003，配置遥控设备903发布消息时的目的地址为所述群组的目的组播地址OxC003，并配置群组中的第二投屏设备905和第三投屏设备906订阅的地址均为所述群组的目的组播地址OxC003。从而，订阅了目的组播地址的第二投屏设备905和第三投屏设备906可处理遥控设备903发布的消息，没有订阅目的组播地址的设备不可处理遥控设备903发布的消息，即第二投屏设备905和第三投屏设备906组成的群组可处理遥控设备903发布的消息。遥控设备903可从控制显示设备902切换至控制第二投屏设备905和第三投屏设备906。
显示设备作为配置设备，若为遥控设备从控制多个投屏设备中的多个设备切换至控制另 外的多个设备的情形，即，逻辑上的群组发生变化的情形，则显示设备可以重新分配目的组播地址，重新配置遥控设备发布消息时的目的地址和投屏设备订阅的地址。在一些实施例中，显示设备还可以配置当前控制投屏设备中未被选择控制的投屏设备从订阅列表中删除原先订阅的目的组播地址。
在一些实施例中，显示设备可从组播地址[OxC000,OxFEEE]中重新分配目的组播地址。显示设备可通过Config Model Subscription Delete配置当前投屏设备中未被选择控制的投屏设备从订阅列表中删除原来的目的组播地址。具体的，显示设备可通过Config Model Subscription Delete发送删除订阅的原来的目的组播地址的消息至当前投屏设备中未被选择控制的投屏设备，当前投屏设备中未被选择控制的投屏设备可从订阅列表中删除原来的目的组播地址，则后续未被选择控制的投屏设备不可再接收遥控设备发布的消息，即遥控设备不再控制未被选择控制的投屏设备。
例如，如图9所示，若为遥控设备903从控制第一投屏设备904和第二投屏设备905切换至控制第二投屏设备905和第三投屏设备906的情形，则需要执行上述的一投一的场景下的投屏设备(例如第一投屏设备904和/或第二投屏设备905)将遥控设备产生的控制设备切换请求进行中转，然后，显示设备902显示控制设备选择界面，接着，根据用户选择第二投屏设备905和第三投屏设备906的操作，遥控设备901产生选定目标控制设备指令，显示设备902则根据选定目标控制设备指令确定目标控制设备为第二投屏设备905和第三投屏设备906。此时，由于用户的选择操作，逻辑上的群组由包括第一投屏设备904和第二投屏设备905变化为新的包括第二投屏设备905和第三投屏设备906的群组。接着，显示设备902为新的群组专门分配目的组播地址OxC005，配置遥控设备903发布消息时的目的地址为新的群组的目的组播地址OxC005，并配置新的群组中的第二投屏设备905和第三投屏设备906订阅的地址均为新的群组的目的组播地址OxC005。显示设备902还配置第一投屏设备904从订阅列表中删除原来的群组的目的组播地址OxC003。从而，订阅了新的目的组播地址的第二投屏设备905和第三投屏设备906可处理遥控设备903发布的消息，没有订阅新的目的组播地址的设备不可处理遥控设备903发布的消息，即第二投屏设备905和第三投屏设备906组成的新的群组可处理遥控设备903发布的消息。遥控设备903则可从控制第一投屏设备904和第二投屏设备905切换至控制第二投屏设备905和第三投屏设备906。
显示设备作为配置设备，若为遥控设备从控制多个投屏设备中的多个设备切换至控制多个投屏设备和显示设备中的一个设备的情形，则显示设备根据选择控制的设备配置遥控设备发布消息时的目的地址为选择控制的设备的单播地址，并配置当前控制设备中未被选择控制的设备从订阅列表中删除目的组播地址。其中，显示设备配置遥控设备发布消息时的目的地址为选择控制的设备的单播地址的过程与上述一投一的场景下的显示设备配置遥控设备发布消息时的目的地址为投屏设备的单播地址的过程相似，在此不再赘述。显示设备配置当前控制设备中未被选择控制的设备从订阅列表中删除目的组播地址的过程与上述的显示设备配置当前控制投屏设备中未被选择控制的投屏设备从订阅列表中删除原先订阅的目的组播地址的过程相似，在此不再赘述。
例如，如图9所示，若为遥控设备903从控制第一投屏设备904和第二投屏设备905切换至控制第三投屏设备906的情形，则需要执行上述的投屏设备(例如第一投屏设备904和/或第二投屏设备905)将遥控设备903产生的控制设备切换请求进行中转，然后，显示设备902 根据选定目标控制设备指令确定目标控制设备为第三投屏设备906。接着，显示设备902配置遥控设备903发布消息时的目的地址为第三投屏设备906的单播地址，并配置第一投屏设备904和第二投屏设备905从订阅列表中删除原来的目的组播地址OxC003。从而，遥控设备903可从控制第一投屏设备904和第二投屏设备905切换至控制第三投屏设备906。
请参考图10，为本申请实施例提供的控制设备切换方法的另一流程图。所述控制设备切换方法应用于一投多的场景。在一投多的场景下，如图11所示，一个投屏设备1101将音频、视频、文档等投屏到多个显示设备1102上分屏显示，多个显示设备1102包括第一显示设备1103和第二显示设备1104，第一显示设备1103配有一个遥控设备1105。第二显示设备1104的数量可为一个或多个。下面为了描述的方便，以第二显示设备1104的数量为一个进行描述，但是可理解，第二显示设备1104的数量还可为多个，本申请对此不作限制。
在一投多的场景下，第一显示设备1103可作为配网设备和配置设备，投屏设备1101也可作为配网设备和配置设备。第一显示设备1103可作为配网设备将遥控设备1105和投屏设备1101加入Mesh网络中。其中，步骤S1001为第一显示设备1103作为配网设备将遥控设备1105加入Mesh网络中；步骤S1003为第一显示设备1103作为配网设备将投屏设备1101加入Mesh网络中。第一显示设备1103还可作为配置设备配置投屏设备1101的地址和遥控设备1105的地址。其中，步骤S1002为第一显示设备1103作为配置设备配置遥控设备1105的目的地址为第一显示设备1103的单播地址，使得遥控设备1105可控制第一显示设备1103；步骤S1004为第一显示设备1103作为配置设备配置投屏设备1101的目的地址为第一显示设备1103的单播地址，使得第一显示设备可处理投屏设备1101发布的消息。
投屏设备1101可作为配网设备将第二显示设备1104加入Mesh网络中。其中，步骤S1005-步骤S1010为投屏设备1101作为配网设备将第二显示设备1104加入Mesh网络中。投屏设备1101还可作为配置设备配置第二显示设备1104的目的地址。其中，步骤S1011为投屏设备1101作为配置设备配置第二显示设备1104的目的地址为投屏设备1101的单播地址，使得投屏设备1101可处理第二显示设备1104发布的消息。
投屏设备1101还转发将第二显示设备1104加入Mesh网络中时分发的配网数据至第一显示设备1103，从而第一显示设备1103还可以作为配置设备，如同步骤S1019所述，配置遥控设备发布消息时的目的地址为第二显示设备的单播地址。所述配网数据可以包括密钥和第二显示设备的单播地址。
步骤S1013-S1021为第一显示设备1013根据对遥控设备1105的操作确定目标控制设备为第二显示设备701，从而第一显示设备1013可根据目标控制设备配置遥控设备1105的目的地址，使得遥控设备1105控制第二显示设备1104。
在一投多的场景下，遥控设备1105在控制第一显示设备1103和控制投屏设备1101之间进行切换的过程，与图6中的一投一的场景下遥控设备在控制显示设备和控制投屏设备之间进行切换的过程相同，在此不再赘述。下面介绍在一投多的场景下，遥控设备从控制第一显示设备切换至控制第二显示设备的情形下的控制设备切换方法。所述控制设备切换方法包括：
S1001：第一显示设备将遥控设备加入Mesh网络中。
所述第一显示设备将遥控设备加入Mesh网络中的过程与一投一场景中的显示设备将遥控设备加入Mesh网络中的过程(步骤S601-S605)相同，在此不再赘述。
S1002：第一显示设备配置遥控设备发布消息时的目的地址为第一显示设备的单播地址。

S1003：第一显示设备将投屏设备加入Mesh网络中。
所述第一显示设备将投屏设备加入Mesh网络中的过程与一投一场景中显示设备将投屏设备加入Mesh网络中的过程(步骤S607-S611)相同，在此不再赘述。
S1004：第一显示设备配置投屏设备发布消息时的目的地址为第一显示设备的单播地址。本实施例中的步骤S1004与一投一场景中的步骤S612相似，具体请参阅一投一场景中对步骤S612的详细描述，在此不进行赘述。
S1005：第一显示设备通过第一传输通道向投屏设备发送提示信息，所述第一传输通道为第一显示设备与投屏设备建立投屏连接后形成的通道。
在一些实施例中，第一显示设备可在满足第三预设条件时通过第一传输通道向投屏设备发送提示信息。所述第三预设条件可为，例如，第一显示设备和第二显示设备与投屏设备建立投屏连接之后，或者第一显示设备与遥控设备根据GATT协议建立蓝牙连接之后。可理解，第三预设条件还可为其他条件，本申请对此不作限制。
S1006：投屏设备根据提示信息通过第二传输通道向第二显示设备发送第三配网通知，所述第二传输通道为第二显示设备与投屏设备建立投屏连接后形成的通道。
S1007：第二显示设备根据第三配网通知以广播的方式发送第三入网申请。
在一些实施例中，第二显示设备根据第三配网通知对外广播为Mesh Beacon报文的第三入网申请。所述Mesh Beacon报文用于声明自己是未入网设备。所述Mesh Beacon报文可以为Unprovisioned Device Beacon报文。
S1008：投屏设备通过扫描发现第三入网申请。
投屏设备可在发送第三配网通知后开始扫描，本申请对此不作限制。
在一些实施例中，投屏设备对扫描事件进行监听。若投屏设备监听到第二显示设备发送的Mesh Beacon报文，则投屏设备通过扫描发现第三入网申请。
S1009：投屏设备根据发现的第三入网申请对第二显示设备进行配网。
在一些实施例中，投屏设备对第二显示设备进行配网包括投屏设备向第二显示设备发起配网邀请、第二显示设备向投屏设备发送配网能力、投屏设备和第二显示设备交换公钥、投屏设备和第二显示设备进行身份认证、投屏设备向第二显示设备分发配网数据等步骤中的一种或多种。配网数据可以包括密钥和第二显示设备的单播地址。
S1010：所述第二显示设备存储投屏设备分发的第二显示设备的单播地址。
在一些实施例中，第二显示设备的单播地址可唯一的标识Mesh网络中的第二显示设备。从而，第二显示设备的单播地址可使得Mesh网络中的其他节点识别出来是第二显示设备在发布消息。
S1011：投屏设备配置第二显示设备发布消息时的目的地址为投屏设备的单播地址。
在一些实施例中，投屏设备可以通过Config Model Publication Set配置第二显示设备发布消息时的目的地址为投屏设备的单播地址。具体的，投屏设备可通过Config Model Publication Set发送投屏设备的单播地址给第二显示设备，第二显示设备可将第二显示设备发布消息时的目的地址设为投屏设备的单播地址。从而，在Mesh网络中，对于第二显示设备所发布的消息，投屏设备可进行处理。
S1012：投屏设备将投屏设备与第二显示设备组网时分发的配网数据发送给第一显示设备。
投屏设备还将投屏设备与第二显示设备组网时分发的配网数据发送给第一显示设备，从而第一显示设备可作为配置者配置第二显示设备的地址。所述配网数据可以包括密钥和第二显示设备的单播地址。
通过上述的第一显示设备与遥控设备的组网，第一显示设备与投屏设备的组网，以及投屏设备与第二显示设备的组网，第一显示设备、第二显示设备、遥控设备及投屏设备均处于同一Mesh网络中。在第一显示设备、第二显示设备、遥控设备、及投屏设备组网后，可进行下面描述的切换控制设备操作：
S1013：遥控设备响应于作用在遥控设备上的按键的第一操作，产生控制设备切换请求。
本实施例中的步骤S1013与一投一场景中的步骤S613相似，具体请参阅一投一场景中对步骤S613的详细描述，在此不进行赘述。
S1014：遥控设备向第一显示设备发送控制设备切换请求，相应地，第一显示设备接收遥控设备发送的控制设备切换请求。
本实施例中的步骤S1014与一投一场景中的步骤S614相似，具体请参阅一投一场景中对步骤S614的详细描述，在此不进行赘述。
S1015：第一显示设备根据控制设备切换请求显示控制设备选择界面。
本实施例中的步骤S1015与一投一场景中的步骤S615相似，具体请参阅一投一场景中对步骤S615的详细描述，在此不进行赘述。
此时，可供用户选择的目标控制设备可以包括第一显示设备、第二显示设备和投屏设备，因此控制设备选择界面中可以包含第一显示设备的图标/名称/标识、第二显示设备的图标/名称/标识和投屏设备的图标/名称/标识。
S1016：遥控设备响应于作用在遥控设备上的按键的第四操作，产生焦点转移指令。
本实施例中的步骤S1016与一投一场景中的步骤S616相似，具体请参阅一投一场景中对步骤S616的详细描述，在此不进行赘述。
S1017：遥控设备向第一显示设备发送焦点转移指令，相应地，第一显示设备接收遥控设备发送的焦点转移指令。
本实施例中的步骤S1017与一投一场景中的步骤S617相似，具体请参阅一投一场景中对步骤S617的详细描述，在此不进行赘述。
S1018：第一显示设备根据焦点转移指令转移焦点的位置至第二显示设备。
本实施例中的步骤S1018与一投一场景中的步骤S618相似，具体请参阅一投一场景中对步骤S618的详细描述，在此不进行赘述。
S1019：遥控设备响应于作用在遥控设备上的按键的第五操作，产生选定目标控制设备指令。
本实施例中的步骤S1019与一投一场景中的步骤S619相似，具体请参阅一投一场景中对步骤S619的详细描述，在此不进行赘述。
S1020：遥控设备向第一显示设备发送选定目标控制设备指令，相应地，第一显示设备接收遥控设备发送的选定目标控制设备指令。
本实施例中的步骤S1020与一投一场景中的步骤S620相似，具体请参阅一投一场景中对 步骤S620的详细描述，在此不进行赘述。
S1021：第一显示设备根据选定目标控制设备指令确定目标控制设备为第二显示设备。
本实施例中的步骤S1021与一投一场景中的步骤S621相似，具体请参阅一投一场景中对步骤S621的详细描述，在此不进行赘述。
S1022：第一显示设备根据确定的第二显示设备配置遥控设备发布消息时的目的地址为第二显示设备的单播地址。
由于在步骤S1012中，投屏设备还将投屏设备与第二显示设备组网时投屏设备为第二显示设备分发的配网数据发送给了第一显示设备，也就是说，第一显示设备获取到了第二显示设备的配网数据，第二显示设备的配网数据中包括第二显示设备的单播地址。从而，在步骤S1022中，第一显示设备可根据确定的第二显示设备配置遥控设备发布消息时的目的地址为第二显示设备的单播地址。
第一显示设备根据确定的第二显示设备配置遥控设备发布消息时的目的地址为第二显示设备的单播地址的过程与显示设备根据确定的投屏设备配置遥控设备发布消息时的目的地址为投屏设备的单播地址的过程相同，在此不再赘述。
可以理解的是，遥控设备在从控制第一显示设备切换至控制第二显示设备后，用户可能希望遥控设备从控制第二显示设备切换至控制投屏设备或者第一显示设备。下面简单介绍遥控设备从控制第二显示设备切换至控制投屏设备：
遥控设备可执行上述步骤S1013的过程，由于遥控设备此时控制第二显示设备，第一显示设备无法处理遥控设备发布的控制设备切换请求，因此，需要第二显示设备和投屏设备将控制设备切换请求进行中转。具体地，在一些实施例中，可预先设置第二显示设备和投屏设备接收到控制设备切换请求后重新发布所述控制设备切换请求。由于遥控设备此时控制第二显示设备，第二显示设备可处理遥控设备发布的控制设备切换请求。第二显示设备在接收到遥控设备发布的控制设备切换请求后，对控制设备切换请求进行重新发布处理至投屏设备；由于在步骤S1011中，投屏设备已配置第二显示设备发布消息时的目的地址为投屏设备的单播地址，投屏设备可处理第二显示设备发布的控制设备切换请求。投屏设备在接收到第二显示设备发布的控制设备切换请求后，可对控制设备切换请求进行重新发布处理至第一显示设备。第一显示设备接收到投屏设备重新发布的控制设备切换请求后，第一显示设备可通过如同上述步骤S1015的过程，根据控制设备切换请求显示控制设备选择界面。用户看到控制设备选择界面后，可以选择投屏设备作为目标控制设备。具体地，在一些实施例中，遥控设备还可类似上述步骤S1016和S1019的过程产生指令并发送指令至第一显示设备，第一显示设备还可类似上述步骤S1017-S1018的过程和类似上述步骤S1020-S1021的过程，确定目标控制设备为投屏设备。进而，在选择投屏设备作为目标控制设备之后，第一显示设备还可配置遥控设备发布消息时的目的地址为第一显示设备的单播地址的过程，从而将遥控设备从直接控制第二显示设备切换至直接控制投屏设备。
可理解，遥控设备从控制第二显示设备切换至控制第一显示设备的过程与上述的遥控设备从控制第二显示设备切换至控制投屏设备的过程相似，在此不再赘述。
可理解，遥控设备从控制投屏设备切换至控制第二显示设备的过程与图6中遥控设备从控制投屏设备切换至控制显示设备的过程相似，在此不再赘述。
可理解，本申请实施例提供的控制设备切换方法，还可省略投屏设备，则遥控设备可在 直接控制第一显示设备和直接控制第二显示设备之间进行切换。例如，控制设备切换系统包括一个遥控设备，一个第一显示设备和一个第二显示设备，开始时遥控设备控制第一显示设备，则第一显示设备可配置遥控设备发布消息时的目的地址为第二显示设备的地址，使得遥控设备由控制第一显示设备切换为控制第二显示设备。
可理解，若第二显示设备的数量为多个，遥控设备还可从控制多个第二显示设备中的一个第二显示设备切换至控制多个第二显示设备中的另一第二显示设备。遥控设备从控制多个第二显示设备中的一个第二显示设备切换至控制多个第二显示设备中的另一第二显示设备的过程，与上述的遥控设备从控制一个第二显示设备切换至控制第一显示设备的过程相似，在此不再赘述。
请参考图12，为本申请实施例提供的控制设备切换方法的另一流程图。所述控制设备切换方法应用于包括第一设备、第二设备和第三设备的系统中。所述第三设备用于控制所述第一设备和/或所述第二设备。所述控制设备切换方法包括：
S1201：在所述第三设备用于控制所述第一设备的情况下，所述第一设备接收第一控制设备切换请求。
在一些实施例中，所述第一设备为显示设备，所述第二设备为投屏设备，所述第二设备用于将投屏内容通过所述第一设备和所述第二设备之间的传输通道发送给所述第一设备，以使得所述第一设备用于显示所述投屏内容。
在一些实施例中，所述第三设备用于控制所述第一设备的情况，具体包括：所述第三设备发布消息时的所述目的地址为所述第一设备的地址的情况。在一些实施例中，所述第一设备的地址是所述第一设备为所述第一设备分配的地址。
