在一些实施例中，针对不同的使用场景，多窗口显示的画面内容可以不同。图5c为根据一些实施例的分屏模式中四分屏的显示效果示意图，例如，如图5c所示，在显示设备200进入到分屏模式中的四分屏展示时，显示器260可将用户界面划分为四个区域，分别显示第一窗口、第二窗口、第三窗口和第四窗口，在第一窗口中显示着应用列表，在第二窗口中显示中应用列表，在应用列表中排布多个应用程序的相关控件。在第三窗口中显示第三媒资的播放画面，在第四窗口中显示第四媒资的播放画面。也就是说，在分屏模式下，不同窗口可以同时显示不同类型的界面，各个窗口之间互不干扰。
在一些实施例中，用户可以通过特定的交互动作控制显示设备200进入分屏模式。图6a为根据一些实施例的通过按键切换分屏模式的显示效果示意图，如图6a所示，可以在显示设备200配套的控制装置100上设置分屏模式切换按键，当用户按下该分屏模式切换按键时，可以控制显示设备200进入或退出分屏模式，即控制显示设备200的显示器260显示多个窗口或单个窗口。还可以在显示设备200的UI界面中设置分屏模式切换选项，当用户点击该切换选项时，可以控制显示设备200进入或退出分屏模式。图6b为根据一些实施例的通过切换选项切换分屏模式的显示效果示意图，如图6b所示，示例性示出了根据一些实施例的通过切换选项切换分屏模式的显示效果示意图。还可以在显示设备200的UI界面中设置分屏模式切换选项，当用户点击该切换选项时，可以控制显示设备200进入或退出分屏模式。在一些实施例中，用户可以通过语音控制显示设备200进入或退出分屏模式。例如，在用户输入唤醒词“嗨！××”后，对显示设备200输入“切换至分屏模式”的语音指令，显示设备200即可进入分屏模式。
在一些实施例中，显示设备200还可以对用户的使用状态实时检测，并判断用户是否具有多窗口显示的需求，从而根据用户需求智能切换分屏模式或提供分屏模式切换选项。图6c为根据一些实施例的一种自动切换分屏模式的显示效果示意图，如图6c所示，在显示设备200展示媒资画面的过程中，如果有视频聊天请求，则可以自动切换至分屏模式，使得显示设备200可以通过第一窗口显示媒资画面；同时通过第二窗口显示视频聊天画面。 图6d为根据一些实施例的另一种自动切换分屏模式的显示效果示意图，如图6d所示，在显示设备200播放媒资画面的过程中，还可以在用户界面的右侧显示多个推荐节目选项，当用户选中任一推荐节目选项并确认后，可以控制显示设备200进入分屏模式，即原媒资播放画面通过第一窗口显示，推荐节目对应的播放画面通过第二窗口显示。
在一些实施例中，显示设备200的控制装置100有触控屏、遥控器、鼠标等多种，于安卓***中，触控屏或者鼠标基于坐标计算位置，其点击事件在安卓中为Touch(触控)事件，触控屏或者鼠标可以将触控事件分发给与该位置相对应的应用，使得焦点传递至相应的应用。图6e为根据一些实施例的触控事件分发的显示效果示意图，如图6e所示，当前焦点的位置位于第二窗口，触控事件指向了第一窗口，则显示设备200件触控事件分发至第一窗口。图6f为根据一些实施例的触控事件分发的时序图，如图6f，显示设备200接收到一个含有(x，y)坐标信息的Touch事件，输入触发器(InputFlinger)会先获取***服务中任务栈的窗口信息，即当前窗口信息，然后根据坐标判断此Touch事件是在哪个应用显示范围内触发的，也就是查找点击坐标对应的窗口应用，随后直接分发按键给坐标对应的应用，不考虑当前焦点所在的任务栈。对于遥控器设备而言，只能将按键分发给位于最顶层的应用。图6g为根据一些实施例的输入事件分发的时序图，结合图6g，显示设备200接收到一个Input事件，Input事件无坐标信息只有按键值信息，所以输入触发器会从***服务中获取当前焦点所在的任务栈，在查询到当前焦点位于第二窗口应用时，将按键分发到第二窗口所在的任务栈中。
在一些实施例中，显示设备200还可以对用户的使用状态实时检测，并判断用户是否具有多窗口显示的需求，从而根据用户需求智能切换分屏模式或提供分屏模式切换选项。例如，在显示设备200展示媒资画面的过程中，如果有视频聊天请求，则可以自动切换至分屏模式，使得显示设备200可以通过第一窗口显示媒资画面；同时通过第二窗口显示视频聊天画面。显示设备200中设置有投屏应用，通过投屏应用基于一定的投屏协议与投屏设备进行连接，能够满足用户利用投屏协议将投屏设备的投屏内容展示在显示器上。例如，在一些实施例中，显示设备可以基于同一投屏服务，让多个支持同一投屏协议投屏设备向同一显示设备进行投屏，同步在同一用户界面上展示多个投屏设备的投屏界面。这里，投屏设备可以为手机、平板电脑、计算机、笔记本电脑，智能电视等。
在一些实施例中，控制器被配置为执行多设备投屏同屏显示的控制过程。首先，控制器250响应于多个投屏设备的投屏请求，与多个所述投屏设备建立连接，其中，多个投屏设备支持同一投屏协议。控制器250接收多个所述投屏设备所发送的投屏内容，并判断投屏内容的形式。控制器250根据最后接入的所述投屏设备的投屏内容的形式确定后续投屏展示的形式，这里，投屏内容的形式指的是竖向媒资和横向媒资，投屏展示的形式指的是多窗口展示和全屏展示。
在一些实施例中，显示设备200在投屏应用中设置有投屏模式的选择控件，当用户点击该选择控件后，可选择当前所需要的投屏模式。当用户选中了投屏模式中的智能模式时，在最后接入的所述投屏设备的投屏内容为竖向媒资时，控制器250控制多个窗口分别对应展示多个所述投屏设备的投屏内容。在最后接入的所述投屏设备的投屏内容为横向媒资时，控制器250控制所述显示器全屏展示最后接入的所述投屏设备的投屏内容。
在一些实施例中，除了上述智能模式以外，显示设备200中的投屏应用还包括全屏模式和分屏模式。其中，全屏模式指的是显示设备200控制所述显示器260全屏展示最后接 入的所述投屏设备的投屏内容。分屏模式指的是不管最后接入的投屏设备的投屏内容的形式是横向媒资还是竖向媒资，均将多个所述投屏设备的投屏内容分别于多个所述窗口进行展示。
在一些实施例中，在显示设备200中的投屏应用中，设置有投屏模式的选择控件，当用户点击该选择控件后，选择控件展示出选择列表，在选择列表中设置有全屏模式、分屏模式及智能模式，用户可通过选择列表选择当前所需要的投屏模式。需要说明的是，此处投屏模式中的分屏模式即针对于显示设备200中多窗口显示的分屏模式。
<同一投屏协议下多设备投屏同屏展示>
图7示例性示出了根据一些实施例的同一投屏协议下多投屏设备投屏流程示意图。如图7所示，以两个投屏设备为例进行说明。投屏设备A、投屏设备B通过同一投屏协议与显示设备200建立相关的协议连接，进行投屏相关操作。通过协议层约定，通讯过程中携带相关的协议信息，例如，基于NFC，投屏设备能够拿到显示设备200的设备信息、网络信息等。显示设备200在发现投屏设备A和B之后，监听投屏设备A和B的连接。如图7中所示，在显示设备200通过同一投屏服务与各个投屏设备建立连接后，再根据投屏模式的设置，于显示器260上按照全屏模式、分屏模式或者智能模式进行展示。
在一些实施例中，显示设备200通过同一投屏服务接收多个所述投屏设备的投屏请求，进行客户端Group(组)管理，分指令通道和数据通道进行业务承接，其中，通过指令通道进行相关协议的交互，通过数据通道进行视频流的传输。显示设备200响应于投屏请求，利用投屏服务监听投屏设备连接，对投屏设备进行组管理，其中，不同的所述投屏设备对应组内不同成员。投屏服务接收到投屏设备的投屏请求后，将对应的投屏设备进行客户端Group的建立，不同的投屏设备对应客户端Group的不同成员，每个成员内有对应的投屏设备信息以及协议交互信息。在不同的所述投屏设备对应组内不同成员时，控制器250控制投屏设备绑定相应的设备标识，其中，所述设备标识用于区分组内不同成员。多个投屏设备通过同一协议进行投屏展示时，通过客户端Group以及分屏处理中心处理可以实现在同一投屏协议下，多个投屏设备在不同的Activity栈内并行展示投屏界面，且相互不干扰。
图8a-图8b为根据一些实施例的同一投屏协议下多投屏设备与显示设备建立连接的示意图，在一些实施例中，显示设备200投屏服务建立一个客户端Group，投屏服务需要根据发送投屏请求的投屏设备的个数建立对应子投屏通道，接收到投屏设备的投屏请求后，在当前客户端Group内增加一个子成员。如图8a所示，不同的投屏设备对应客户端Group的不同成员，每个成员内有对应的投屏设备信息以及协议交互信息。如图8b所示，当显示设备200响应投屏设备A投屏请求，即投屏设备A与显示设备200连接成功后，下一步要进行视频流的传输，此时查询客户端Group内投屏设备的连接个数，启动分屏处理中心，进行不同投屏形态的呈现。
<不同投屏协议下多设备投屏同屏展示>
图9a为根据一些实施例的不同投屏协议下多投屏设备投屏流程示意图，如图9a所示，显示设备200通过不同投屏服务分别接收多个所述投屏设备的投屏请求，投屏设备A、投屏设备B通过不同投屏协议与显示设备建立相关的协议连接，进行投屏相关操作。通过协议层约定，通讯过程中携带相关的协议信息，例如，基于NFC(Near Field Communication， 进场通信)，投屏设备能够拿到显示设备200的设备信息、网络信息等。显示设备200响应于投屏请求，通过不同投屏协议的投屏服务接收监听投屏设备的投屏请求，利用投屏服务监听投屏设备连接，搭建指令通道和数据通道，其中，指令通道用于投屏设备和所述显示设备之间的指令交互，所述数据通道用于所述投屏设备和所述显示设备之间的数据交互。如，显示设备200中的投屏服务A接收投屏设备A的投屏请求，投屏服务B接收投屏设备B的投屏请求，投屏服务负责监听投屏设备连接，与投屏设备议建立指令通过和数据通道。通过指令通道，显示设备200能够接收用户通过投屏设备发送的请求，并且通过数据通道，显示设备200能够接收到投屏设备所发送的相关视频数据等。待指令及数据通道建立完成后，投屏设备与显示设备200建立连接。如图9a中所示，在显示设备200通过不同投屏服务与各个投屏设备建立连接后，再根据投屏模式的设置，于显示器260上按照全屏模式、分屏模式或者智能模式进行展示。
在一些实施例中，显示设备200通过不同协议的投屏服务进行投屏设备的发现，发现投屏设备后，进行投屏设备的连接。例如，在多个所述投屏设备分别支持NFC、Airplay(无线投屏技术)及DLNA(DIGITAL LIVING NETWORK ALLIANCE，数字生活网络联盟)投屏协议时，控制器250利用NFC协议服务接收支持NFC协议的投屏设备的投屏请求，并利用NFC协议服务监听投屏设备连接。又如，控制器250利用Airplay协议服务接收支持Airplay协议的投屏设备的投屏请求，并利用Airplay协议服务监听投屏设备连接。再如控制器250利用DLNA协议服务接收支持DLNA协议的投屏设备的投屏请求，并利用DLNA协议服务监听投屏设备连接。其中，NFC投屏是基于NFC协议双向进行设备的发现以及连接，Airplay投屏是基于Airplay协议双向进行设备的发现以及连接，DLNA推送是通过DLNA协议进行投屏设备的发现及连接，其他协议也如此，均是通过各自协议的约定进行投屏设备的发现及连接。其中，Airplay投屏是指苹果开发的一种无线技术，可以通过WiFi将手机、平板等iOS设备上的包括图片、音频、视频通过无线的方式传输到支持AirPlay设备。
在一些实施例中，在投屏设备与显示设备200建立连接后，显示设备200通过应用层中枢模块负责对投屏设备的管理。图9b为根据一些实施例的应用层中枢模块的示意图，如图9b所示，应用层中枢模块可以进行两个方面的管理。一是连接管理，其负责对于显示设备200进行投屏连接的投屏设备的数据进行梳理，为投屏设备视频流最终展示的效果做准备。二是视频流管理，其负责将各个不同投屏协议过来的视频流进行分类解码处理。
在一些实施例中，投屏设备A与显示设备200建立连接后，然后通知应用层中枢模块，以便应用层中枢模块进行连接管理。当投屏设备A要进行投屏内容发送时，应用层中枢模块对当前连接的所有设备成员进行梳理，再结合用户对投屏模式的设置，根据需求启动分屏处理中心，进行不同投屏形态的呈现。
<单设备投屏>
以显示设备200接入一个投屏设备A为例，即Group内投屏设备的连接个数为1个，分别描述在不同投屏模式下的投屏状态。图10为根据一些实施例的全屏模式下单设备投屏的显示效果示意图,在一些实施例中，当显示设备200判定出当前的投屏模式为全屏模式时，在投屏设备A通过数据通道向显示设备200发送投屏内容后，显示设备200可直接将投屏内容全屏显示于显示器260上，如图10所示，在全屏模式下将投屏设备A的投屏内容展示于显示器260上，其投屏内容可以为投屏设备A的操作界面。
在一些实施例中，当显示设备200判定出当前的投屏模式为分屏模式时，可以进一步根据用户的需求，判断是否将显示设备200当前用户界面进行同步展示，也就是将显示设备200的TOP(顶层)应用(或者前台应用)与投屏设备的投屏界面同时置于显示器260所显示的用户界面上。例如，如图10所示，当投屏设备A传输过来的投屏内容是竖向媒资，其所展示的投屏界面也是竖向的，那在显示设备200展示时，左右两侧会有黑框，使得用户体验较差。如若此时，将显示设备200的TOP应用同时展示于显示器260上，那用户通过显示设备200既可以操作TOP应用，又可以观看投屏设备的投屏界面，提高用户体验。当然，若不同步展示用户界面所显示内容，则将多个所述投屏设备的投屏内容分别于多个所述窗口进行展示，也就是说若是用户不需要同步展示TOP应用，那也可只展示投屏设备的投屏内容。
在分屏模式下，若是用户想要同步展示当前用户界面和投屏界面时，需要先通过分屏处理中心判断此时当前用户界面支不支持分屏模式。在当前用户界面支持分屏展示时，启动相应数量的窗口，将用户界面及多个所述投屏设备的投屏内容通过活动管理器接口分别推送至多个所述窗口。在当前用户界面不支持分屏展示时，启动相应数量的窗口，将等比例缩小后的用户界面及多个所述投屏设备的投屏内容通过活动管理器接口分别推送至多个所述窗口。例如，在TOP应用支持分屏时，分屏处理中心根据从应用层中枢模块获取到的已连接的投屏设备的数量为一个，启动显示设备200进入分屏模式下的二分屏，通过调用***分屏接口将TOP应用置于选定的窗口显示，并将投屏设备的投屏界面置于另一个窗口显示。图11-图12为根据一些实施例的分屏模式下单设备投屏的显示效果示意图，如图11所示，将TOP应用和投屏设备A的投屏界面于两个窗口进行展示。在TOP应用不支持分屏时，分屏处理中心可以强制性的将当前TOP应用等比例缩小，如图12所示，将等比例缩小后的TOP应用放置于其中一个窗口进行展示，将投屏设备的投屏界面置于另一个窗口显示。
在一些实施例中，在接收到投屏设备A的投屏内容后，重新启动投屏界面，在当前用户界面支持分屏时，首先分屏处理中心将屏幕分为两半，并将当前用户界面的位置设置为左侧，通过重新设置用户界面的坐标和宽高以实现用户界面等比例缩小，同时投屏设备A的投屏内容的位置设置为右侧，这样分屏处理中心启动显示设备200进入分屏模式下的二分屏。
在一些实施例中，当显示设备200在分屏模式下，用户点击了某一个分屏里的视频进行全屏播放，此时，将视频在其所属的分屏窗口内全屏播放。相当于，显示设备200在显示器260所展示的用户界面中同步展示TOP应用和投屏界面时，如图11所示，若此时用户点击了投屏设备A投屏界面内的某一视频进行全屏播放，则将该视频在投屏设备A的投屏界面所在的窗口内全屏播放。
在一些实施例中，当显示设备200判定出当前的投屏模式为智能模式时，显示设备200会接收投屏设备所发送过来的投屏内容，根据当前投屏内容的显示比例，判定当前投屏内容的最优显示比例。在投屏设备A所发送的投屏内容是横向媒资，也就是投屏数据为横向码流时，如推送过某一视频，此时为了保证用户的视觉体验，显示设备200将该投屏内容全屏播放。图13为根据一些实施例的智能模式下单设备投屏的显示效果示意图，如图13所示，投屏设备A所发送的投屏内容为一横向媒体资源，则显示设备200控制显示器260全屏展示该媒体资源。在投屏设备A所发送的投屏内容是竖向媒资，也就是投屏数据 为竖向码流时，如手机操作页面，若是将该投屏数据全屏展示，在投屏界面的两侧会显示有黑框，此时，为了更好的用户体验，显示设备200选择进入分屏模式，仅将投屏界面置于一个窗口展示，并将显示设备当前用户界面于另一个窗口展示，即同步展示当前用户界面和投屏界面。
<多设备投屏>
以显示设备200接入两个投屏设备，即客户端Group内投屏设备的连接个数为2个，分别描述在不同投屏模式下的投屏状态。图14为根据一些实施例的同一投屏协议下多投屏设备与显示设备建立连接的示意图，如图14所示，显示设备200成功接入投屏设备A和投屏设备B。在一些实施例中，当显示设备200接收到一个投屏设备A的投屏请求并与其建立连接后，首先根据上述投屏状态进行投屏展示，然后，在显示设备200再次接收到第二个投屏设备B的投屏请求并与之建立连接后，通知应用层中枢模块，以便应用层中枢模块进行连接管理。当投屏设备B要进行投屏数据发送时，应用层中枢模块对当前连接的所有设备成员进行梳理，启动分屏处理中心，进行以下不同投屏形态的呈现。
在一些实施例中，参见图7，当显示设备200通过投屏模式设置中判定出当前的投屏模式为全屏模式时，将最后接入的所述投屏设备的投屏内容于所述显示器上全屏展示。即在投屏设备B通过数据通道向显示设备200发送投屏内容后，显示设备200可将之前的投屏直接断掉，直接将投屏设备B所发送的投屏内容全屏显示于显示器260上。也就是说，先把之前接入的投屏设备A的投屏界面断掉，在显示器260所显示的用户界面上更新为当前接入的投屏设备B的投屏界面。
在一些实施例中，参见图7，当显示设备200通过投屏模式设置中判定出当前的投屏模式为分屏模式时，可以根据用户的需求，判断是否需要同步展示出显示设备200端的用户界面所显示内容。在用户需要同步展示用户界面所显示内容和投屏界面时，显示设备200需要先通过分屏处理中心判断此时用户界面所显示内容支不支持分屏模式。在用户界面所显示内容支持分屏时，分屏处理中心根据从应用层中枢模块获取到的已连接的投屏设备的数量为两个，通过应用分屏排版，启动显示设备200进入三分屏状态，通过调用***分屏接口将用户界面所显示内容置于选定的窗口显示，并将两个投屏设备的投屏界面分别置于另外两个窗口显示。如图15所示，显示设备200进行了三分屏，分为第一窗口、第二窗口和第三窗口，将显示设备端的TOP应用放置于第一窗口、投屏设备A的投屏界面放置于第三窗口以及将投屏设备B的投屏界面放置于第二窗口进行展示。在用户界面所显示内容不支持分屏时，分屏处理中心可以强制性的将用户界面所显示内容等比例缩小，并将其放置于其中一个窗口进行展示，将两个投屏设备的投屏界面分别置于另外两个窗口显示。需要说明的是，其展示效果不仅局限于图15中的方式，还可以进行其他方式的排版，如图16所示，将投屏设备A的投屏界面放置于第一窗口、投屏设备B的投屏界面放置于第三窗口以及将TOP应用放置于第二窗口进行展示。
在一些实施例中，针对于图15和图16中的排版方式，需要结合投屏设备所发送的投屏内容的横竖屏模式，如果两个投屏内容均是横向码流，则可选择图16中的排版方式，如果两个投屏内容一横一竖，则选择图15中的排版方式，当然也可以根据产品定义进行展示，不局限上述原则。其中，图15和图16的排版方式可进行切换，可根据投屏设备所发送的投屏内容的横竖向切换以实现自主切换。
在一些实施例中，参见图7，当显示设备200通过投屏模式设置中判定出当前的投屏 模式为智能模式时，显示设备200接收到投屏设备B所发送过来的投屏内容，并根据最后接入的所述投屏设备的投屏内容的显示比例，判定投屏设备B投屏内容的最优显示比例。在投屏设备B所发送的投屏内容为横向码流时，如推送某一视频，此时为了保证用户的视觉体验，显示设备200将该投屏内容全屏播放。在投屏设备B所发送的投屏内容为竖向码流时，如手机操作页面，若是将该投屏内容全屏展示，在投屏界面的两侧会显示有黑框，此时，为了更好的用户体验，显示设备200可充分利用显示器260的显示区域，选择进入分屏模式，仅将投屏设备B投屏界面置于一个窗口展示，并将显示设备的当前用户界面和投屏设备A的投屏界面于另外两个窗口展示，即同步展示显示设备的TOP应用和两个投屏设备的投屏界面。当然，若是此时用户不需要展示TOP应用，显示设备200可进入二分屏状态，仅将两个投屏设备的投屏界面进行展示。
在一些实施例中，显示设备200的全屏模式、分屏模式和智能模式三种投屏模式的实现依附于分屏处理中心，分屏处理中心可以根据当前显示设备200的能力支撑情况，进行分逻辑的处理，根据投屏设备的投屏个数以及当前显示设备200的能力支撑情况进行整体的协调处理，判断当前显示设备200以何种模式启动，以及负责分屏模式的具体执行动作。需要说明的是，显示设备200具体的分屏个数以及展现模式可以进行自定义，不局限本文所述的展现模式。
图17为根据一些实施例的分屏模式下四设备投屏的显示效果示意图，如图17所示，投屏设备A、投屏设备B、投屏设备C和投屏设备D均向显示设备200发送投屏请求，应用层中枢模块梳理接入显示设备200的投屏个数，并通知分屏处理中心。在此，以用户不需要同步展示当前用户界面所显示的内容为例，分屏处理中心控制显示设备进入四分屏，在第一窗口展示投屏设备A的投屏界面，在第二窗口展示投屏设备B的投屏界面，在第三窗口展示投屏设备D的投屏界面以及在第四窗口展示投屏设备D的投屏界面。
图18为根据一些实施例的分屏模式下选定窗口示意图，在图18中，显示设备200处于三分屏状态，分屏处理中心控制TOP应用和两个投屏设备的投屏界面分别于三个窗口中进行展示。需要说明的是，图18中的排版效果仅是业务上所实现的一种呈现模式，用户还可以根据需求进行自定义排版。另外，用户可以通过遥控终端进行对应投屏应用界面的操控，进行界面的操控以及分屏全屏模式的各种切换。
<同一投屏协议下多投屏设备投屏同屏展示的过程>
图19为根据一些实施例的同一投屏协议下多投屏设备投屏的效果示意图，如图19所示，投屏设备A和投屏设备B均基于NFC协议与显示设备200建立连接。首先，投屏设备A和投屏设备B均为支持同一投屏协议的投屏设备，两个投屏设备均与显示设备通过投屏协议服务建立连接。首先根据协议层进行设备的发现，设备发现后，显示设备进行指令监听，于移动端建立指令通道，从而进行指令协议的交互。指令协议交互后达成一致后会进行数据的传输，即视频流的传输，显示设备对投屏设备进行数据监听，在获取投屏设备的投屏数据后进行相应的界面展示。然后，投屏协议需要与客户端Group进行显示设备投屏设备的管理。通过Group内不同的组员实现对投屏设备的管理。大致分两个方面进行管理，一个是连接管理，通过组内成员个数获取与显示设备投屏连接的投屏设备的数量，为视频流最终展示的效果做准备，另一个是视频流管理，将各个投屏设备所发送的视频流进行分类解码处理。
最后，进行投屏视频流展示处理。若是此时显示设备200当前投屏模式为全屏模式， 则显示设备200将最后接入的投屏设备的投屏内容进行全屏展示。若是当前投屏模式为分屏模式，可以分为如下两种排版情况，情况1用户需要同步展示TOP应用的情况，这样过来三路投屏视频流界面后，可以与TOP应用同步展示，以四分屏的方式进行展示；情况2是用户不需要同步展示TOP应用的情况，这样过来的三路投屏视频流界面要进行排版处理，具体各自投屏界面的排版位置可以根据视频流先后顺序进行排版，展现形式不局限于当前模板所示。若是当前投屏模式为智能模式，进一步判断最后接入的投屏设备的投屏内容。若最后接入的投屏设备的投屏内容为竖向媒资，则按照分屏模式下的处理方式，将多个所述投屏设备的投屏内容分别于多个所述窗口进行展示，若最后接入的所述投屏设备的投屏内容为横向媒资，按照全屏模式下的处理方式，则将最后接入的所述投屏设备的投屏内容于所述显示器上全屏展示。
<不同投屏协议下多投屏设备投屏同屏展示的过程>
图20为根据一些实施例的不同协议下多投屏设备投屏的效果示意图，如图20所示，以NFC、Airplay、DLNA投屏为例，显示设备200有相应三个协议的投屏服务，NFC协议服务、Airplay协议服务、DLNA协议服务，用以承接移动端的推送。
步骤一：投屏设备A、投屏设备B和投屏设备C分别与显示设备通过相对应的协议服务建立连接，如，显示设备200通过利用NFC投屏服务接收支持NFC协议的投屏设备A的投屏请求，并利用NFC投屏服务监听投屏设备A连接，利用Airplay投屏服务接收支持Airplay协议的投屏设备B的投屏请求，并利用Airplay投屏服务监听投屏设备B连接，利用DLNA投屏服务接收支持DLNA协议的投屏设备C的投屏请求，并利用DLNA投屏服务监听投屏设备C连接。
图21为根据一些实施例的投屏设备与显示设备建立连接的示意图，如图21所示，投屏设备与显示设备之间建立指令通道和数据通道的过程，首先根据协议层进行设备的发现，设备发现后，显示设备进行指令监听，于移动端建立指令通道，从而进行指令协议的交互。指令协议交互后达成一致后会进行数据的传输，即视频流的传输，显示设备对投屏设备进行数据监听，在获取投屏设备的投屏数据后进行相应的界面展示。
步骤二：各自投屏协议需要与应用层中枢模块进行显示设备投屏设备的管理，也就是在应用层中枢模块进行枢纽处理，大致分两个方面进行管理，一个是连接管理，负责统计与显示设备投屏连接的投屏设备的数量，为视频流最终展示的效果做准备，另一个是视频流管理，视频流管理负责将各个不同投屏协议过来的视频流进行分类解码处理，以使显示设备200在窗口中展示出投屏内容。
步骤三：进行投屏视频流展示处理。若是此时显示设备200当前投屏模式为全屏模式，则显示设备200将最后接入的投屏设备的投屏内容进行全屏展示。若是当前投屏模式为分屏模式，可以分为如下两种排版情况，情况1用户需要同步展示TOP应用的情况，这样过来三路投屏视频流界面后，可以与TOP应用同步展示，以四分屏的方式进行展示；情况2是用户不需要同步展示TOP应用的情况，这样过来的三路投屏视频流界面要进行排版处理，具体各自投屏界面的排版位置可以根据视频流先后顺序进行排版，展现形式不局限于当前模板所示。若是当前投屏模式为智能模式，进一步判断最后接入的投屏设备的投屏内容。若最后接入的投屏设备的投屏内容为竖向媒资，则按照分屏模式下的处理方式，将多个所述投屏设备的投屏内容分别于多个所述窗口进行展示，若最后接入的所述投屏设备的投屏内容为横向媒资，按照全屏模式下的处理方式，则将最后接入的所述投屏设备的投屏内容 于所述显示器上全屏展示。

<焦点切换>
安卓本身存在多窗口，随着窗口的打开，通常情况下是最后打开的窗口拥有焦点安卓对于具有指向性的Touch事件可以直接分发到用户所点击的应用，但是对于Input的事件，由于Input无指向性，所以只能分发到当前焦点所在的任务栈。目前，当显示设备200处于分屏模式时，显示器260所显示的用户界面被划分为多个窗口，对多个窗口来说，用户只能通过控制装置100控制位于用户界面顶层的窗口内的内容，而无法控制其他窗口内的内容。因此，由于用户无法在多个窗口之间进行选择性控制，导致体验效果不佳。
针对上述问题，在一些实施例中提供了一种显示设备，在此，为了便于描述，本申请将具有焦点且响应用户对窗口内所展示内容进行操作的状态称为第一状态，也就是说，在第一状态下，窗口内所展示内容能够获取焦点，如图5c所示，展示有应用列表控件的第一窗口为第一状态下的窗口，该窗口通过焦点框进行标定，在第一窗口内可实现用户对APP的操作。将具有焦点但不响应用户对窗口内所展示内容进行操作的状态称为第二状态，也就是说，第二状态下的窗口上能够获取焦点，第二状态下的窗口也可通过焦点框进行标定，用于提示当前第二状态的窗口位置，需要说明的是，第一状态与第二状态的焦点框的形式不同，可以是颜色不同，可以是线条粗细不同，还可以是线条的形式不同等；将窗口不获取焦点的状态成为第三状态，例如，图5c中的第二窗口、第三窗口和第四窗口均为第三状态下的窗口。
在一些实施例中，在显示设备200进入分屏模式时，即显示器260显示多个窗口时，此时，根据对显示设备200的预先设置，可默认第一窗口为第一状态下窗口，也就是说，在显示设备200进入分屏模式后，用户可通过控制装置100对第一窗口内所展示的内容进行操控。为了指示当前焦点位置，可通过第一标记对第一状态下的窗口进行标定。例如，将第一状态下的窗口通过焦点框进行标定，该焦点框的颜色可以为红色粗线条，在此不做限定。当用户看到通过红色粗线条的焦点框标定的窗口时，即可得知此时该窗口处于第一状态下。
在一些实施例中，在用户对第一状态下的窗口所展示内容进行操作时，显示所述第一标记，在用户对第一状态下的窗口所展示内容不进行操作时，隐藏所述第一标记。也就是说，为了保证用户的视觉体验，显示设备200可仅通过所述第一标记的闪烁状态来提示用户目前被标定为第一状态的窗口是哪个窗口。当用户想要切换窗口，对其他窗口内所展示的内容进行控制时，可以向显示设备200发送触发指令，显示设备200中的控制器250在接收到该触发指令后，触发显示设备200的切换窗口模式。
在一些实施例中，控制器250根据接收到的触发指令将第一状态下的第一窗口标定为第二状态，包括：根据所述触发指令，将焦点移动至多个窗口之间，将所述第一窗口的第 一标记更换为第二标记。此时，显示设备200进入切换窗口模式，在该模式下，显示器260上的所有窗口中不存在第一状态下的窗口，仅有第二状态下的窗口，换句话说，在该模式下用户只可以移动焦点进行窗口之间的切换，无法操作窗口内所展示的内容。
在一些实施例中，对于标定为第二状态的窗口来说，可通过所述第二标记进行标定，所述第一标记和所述第二标记为不同形式的焦点框。也就是说，用来标定第二状态的焦点框的形式与标定第一状态的焦点框的形式不同，例如，可以选为绿色细线条。当用户触发显示设备200的切换窗口模式后，通过显示器260上多个窗口的空间排布情况，进一步发出选择指令。控制器250接收用户发出的选择指令，将用户选择的窗口标定为第二状态，并将第一窗口由第二状态标定为第三状态。
在一些实施例中，在控制器250接收到用户发送的选择指令后，计算用户所选定的目标窗口，将目标窗口置于显示器260的最顶层，并将焦点传递至该目标窗口，使得目标窗口标定为第二状态。图5d为一些实施例的在分屏模式下切换窗口的显示效果示意图，如图5d所示，当前第一状态下的窗口为第一窗口，假如用户想要操控第四窗口内的媒资资源，则需要根据第四窗口与第一窗口之间的相对位置，通过遥控器发送“向右”，再“向下”的选择指令，将第四窗口标定为第二状态。在接收到用户发送的确认指令后，将第四窗口标定为第一状态。
在一些实施例中，在控制焦点传递至目标窗口时，焦点所移动至的每一窗口，控制器250均通过第二标记将其标定为第二状态，在焦点移走后，再将其第二状态重置为第三状态。也就是说，在切换窗口模式下，焦点所在的窗口均通过边框标定为第二状态。用户可通过第二标记的移动，判断焦点的移动轨迹以及当前所在的窗口。承接上述例子，图5d中，当用户通过遥控器发送“向右”的选择指令时，控制器控制焦点移动至第二窗口，此时将第二窗口通过绿色细线条的焦点框标定为第二状态，在接收到用户通过遥控器发送“向下”的选择指令时，将焦点移动至第四窗口，并将第四窗口通过绿色细线条的焦点框标定为第二状态，同时，还需将第二窗口重置为第三状态，也就是取消第二标记标定。
在一些实施例中，根据用户的选择指令将用户选择的窗口标定为第二状态后，在接收到用户发出的确认指令，将第二状态下的窗口标定为第一状态，相应的，将该窗口的第二标记更换为第一标记，例如，将该窗口的绿色细线条焦点框标定改为红色粗线条焦点框标定。确认指令可由用户通过遥控器上的“确认”方向键发出。还可以由用户通过语音控制来发出，例如，用户在向显示设备输入唤醒词之后，继续对显示设备200输入“确认当前选择”。以上对根据用户指令控制焦点在多个窗口之间移动的过程进行了说明。当然，用户还可在选定第一状态的窗口后，控制焦点在窗口内进行移动。
在一些实施例中，在显示设备200为分屏模式时，接收用户输入的选择指令，根据选择指令，控制焦点在第一状态下的窗口内的各个应用控件之间传递。焦点所移动至的每一应用控件，均通过背景颜色的改变标定为聚焦应用。当用户想要控制当前第一状态下窗口内的应用程序时，可通过遥控器上的“上、下、左、右”方向键发出选择指令，进而控制选中对应应用程序的控件，被选定的应用程序，可通过背景颜色加深来指示当前应用程序已被选定。
为了进一步解释上述多窗口切换的过程，本申请一些实施例还提供了一种用户界面的控制方法。该用户界面的控制方法包括：控制器250接收用户输入的用于触发切换窗口模式的触发指令，在显示器所显示的用户界面包括多个窗口时，根据所述触发指令将第一状 态下的第一窗口标定为第二状态。进一步接收用户输入的用于选择窗口的选择指令，根据所述选择指令，将用户选择的窗口标定为所述第二状态，并将所述第一窗口由第二状态标定为第三状态，其中，所述第三状态指的是不具有焦点的状态。最后接收用户输入的确认指令，根据所述确认指令，将第二状态下的窗口标定为第一状态。
下面结合附图对该用户界面的控制方法做进一步说明。
图22为根据一些实施例的在分屏模式下切换窗口的焦点传递流程示意图，如图22所示，在一些实施例中，对于显示设备200来说，首先接收用户发送的按键值，即获取按键事件。然后，控制器250判断该按键事件是否是接收到用户所发送的触发指令。若是触发指令，则触发显示设备200进入切换窗口模式，也就是将当前第一状态下的窗口标定为第二状态，将红色粗线条焦点框标定的窗口更改为绿色细线条焦点框标定的窗口，并进一步等待用户做出选择。若不是触发指令，则直接将按键事件分发至当前焦点任务所指向的应用。然后，在接收到用户发送的选择指令时，获取当前焦点任务，即寻找当前焦点所位于哪个窗口。在获取到当前焦点所在位置后，根据用户发送的选择指令计算目标窗口。最后将目标窗口置于顶层，获取到焦点，即将目标窗口标定为第一状态。
在一些实施例中，所述第一状态和所述第二状态下的窗口分别通过第一标记和第二标记进行标定，其中，所述第一标记和所述第二标记为不同形式的焦点框。
在一些实施例中，所述根据所述触发指令将第一状态下的第一窗口标定为第二状态，包括：根据所述触发指令，将焦点移动至多个窗口之间；将所述第一窗口的第一标记更换为第二标记。
在一些实施例中，在用户对所述第一状态下的窗口内的所展示内容进行操作时，显示所述第一标记；在用户对所述第一状态下的窗口内的所展示内容不进行操作时，隐藏所述第一标记。
在一些实施例中，所述根据所述选择指令，将相应的窗口标定为所述第二状态，包括：根据所述选择指令，计算目标窗口；将所述目标窗口置于所述显示器最顶层；控制焦点传递至所述目标窗口，将所述目标窗口标定为所述第二状态。
在一些实施例中，焦点所移动至的窗口，均通过所述第二标记标定为所述第二状态，且在所述焦点移走后，将所述第二状态重置为第三状态。
在一些实施例中，在所述用户界面包含多个窗口时，接收用户输入的选择指令；根据所述选择指令，控制焦点在所述第一状态下的窗口内的各个应用控件之间传递。
下面结合附图，解释一下本申请实施例所提供的显示设备处于分屏模式阶段的数据交互过程。
图23为根据一些实施例的显示设备处于分屏模式阶段的时序图。在一些实施例中，如图23所示，显示设备200基于分屏窗口服务(SplitWindowService)、分屏窗口业务(HSSplitWindowUsercase)和Activity管理服务(ActivityManagerService)之间的数据交互实现分屏模式的启动和应用。首先，对于分屏启动阶段来说，分屏窗口服务在接收到启动分屏模式的指令后，通过调用分屏启动接口控制分屏窗口业务进行分屏模式的启动，分屏窗口业务对应用栈进行操作，把对应的栈放到相应的位置，Activity管理服务通知分屏窗口业务分屏模式启动完成，分屏窗口业务将第一个底层页面获得焦点，即设置默认获得焦点的窗口。例如，分屏窗口业务此时对堆栈进行操作，如果是分屏模式中三分屏，则通过Activity管理服务启动3个堆栈并按显示顺序依次排列，Activity管理服务通过回调通知 分屏窗口业务分屏启动完成，此时将第一个底层Task任务所在的页面获得焦点。然后是分屏应用启动阶段，用户点击某个底层页面上的窗口，也就是在某个窗口中启动应用，分屏窗口服务通过Activity管理服务启动并创建该窗口，并且将焦点移动至该窗口，使该窗口获取焦点。由于显示界面默认都是1080P，因此需要将窗口的大小进行调整，即将其等比例缩小，通过设置位置和宽高的方式改变应用大小，将其改为1080P，并放置在相应的位置。最后，对于多窗口焦点切换来说，分屏窗口服务获得用户输出的按键事件，在接收到触发指令时触发显示设备200进入切换窗口模式，此时分屏窗口业务将焦点设置到外层，即选择窗口所在的task任务，并标注当前是切换窗口模式，当选定窗口后，分屏窗口业务对该当前窗口进行标定提示，用于指示当前焦点位置。在用户按下确认键后，将焦点窗口所在的task任务内的应用设置为获取焦点，进行标注提示以指示焦点当前位置。
当显示设备200处于切换窗口模式时，也就是焦点在多个窗口之间移动时，框架层的窗口获取窗口信息，此处窗口信息包括位置、所在task任务等，框架层的活动响应按键操作。按键移动需要做处理，这时移动的是外层各个窗口之间的焦点，而不是窗口内应用中控件上的焦点。当选定第一状态下的窗口后，将焦点移动至窗口内，也就是用户可在窗口内应用中控件上移动焦点，此时，框架层的窗口、位置、活动参与，按键首先将按键分发到当前窗口，然后再分发给应用，上下左右移动时，会移动应用内控件焦点的位置。
本申请中，在智能电视处于分屏模式时，用户能够实现在不同窗口之间的焦点切换过程，自由操作点击任一窗口内的任一应用程序，极大的提升了用户体验。
为了方便解释，已经结合具体的实施方式进行了上述说明。但是，上述在一些实施例中讨论不是意图穷尽或者将实施方式限定到上述公开的具体形式。根据上述的教导，可以得到多种修改和变形。上述实施方式的选择和描述是为了更好的解释原理以及实际的应用，从而使得本领域技术人员更好的使用实施方式以及适于具体使用考虑的各种不同的变形的实施方式。
