N芯片的应用程序层2912可包含但不限于一个或多个应用程序，如：视频点播应用程序、应用程序中心、游戏应用等。A芯片的应用程序层3912可包含但不限于一个或多个应用程序，如：直播电视应用程序、媒体中心应用程序等。需要说明的是，A芯片和N芯片上分别包含什么应用程序是根据操作系统和其他设计确定的，本申请无需对A芯片和N芯片上所包含的应用程序做具体的限定和划分。
直播电视应用程序，可以通过不同的信号源提供直播电视。例如，直播电视应用程可以使用来自有线电视、无线广播、卫星服务或其他类型的直播电视服务的输入提供电视信号。以及，直播电视应用程序可在显示设备200上显示直播电视信号的视频。
视频点播应用程序，可以提供来自不同存储源的视频。不同于直播电视应用程序，视频点播提供来自某些存储源的视频显示。例如，视频点播可以来自云存储的服务器端、来自包含已存视频节目的本地硬盘储存器。
媒体中心应用程序，可以提供各种多媒体内容播放的应用程序。例如，媒体中心，可以为不同于直播电视或视频点播，用户可通过媒体中心应用程序访问各种图像或音频所提供服务。
应用程序中心，可以提供储存各种应用程序。应用程序可以是一种游戏、应用程序，或某些和计算机系统或其他设备相关但可以在显示设备中运行的其他应用程 序。应用程序中心可从不同来源获得这些应用程序，将它们储存在本地储存器中，然后在显示设备200上可运行。
在一些实施例中，由于A芯片及N芯片中可能分别安装有独立的操作系统，从而使显示设备200中存在两个在独立但又存在相互关联的子系统。例如，A芯片和N均可以独立安装有安卓(Android)及各类APP，使得每个芯片均可以实现一定的功能，并且使A芯片和N芯片协同实现某项功能。
图7中示例性示出了根据示例性实施例中显示设备200中用户界面的示意图。如图7所示，用户界面包括多个视图显示区，示例的，第一视图显示区201和播放画面202，其中，播放画面包括布局一个或多个不同项目。以及用户界面中还包括指示项目被选择的选择器，可通过用户输入而移动选择器的位置，以改变选择不同的项目。
需要说明的是，多个视图显示区可以呈现不同层级的显示画面。如，第一视图显示区可呈现视频聊天项目内容，第二视图显示区可呈现应用层项目内容(如，网页视频、VOD展示、应用程序画面等)。
可选的，不同视图显示区的呈现存在优先级区别，优先级不同的视图显示区之间，视图显示区的显示优先级不同。如，系统层的优先级高于应用层的优先级，当用户在应用层使用获取选择器和画面切换时，不遮挡系统层的视图显示区的画面展示；以及，根据用户的选择使应用层的视图显示区的大小和位置发生变化时，系统层的视图显示区的大小和位置不受影响。
也可以呈现相同层级的显示画面，此时，选择器可以在第一视图显示区和第二视图显示区之间做切换，以及当第一视图显示区的大小和位置发生变化时，第二视图显示区的大小和位置可随及发生改变。
在一些实施例中，图7中的任意一个区域可以显示摄像头获取的画面。
“项目”是指在显示设备200中用户界面的各视图显示区中显示以表示，诸如图标、缩略图、视频剪辑等对应内容的视觉对象。例如：项目可以表示电影、电视剧的图像内容或视频剪辑、音乐的音频内容、应用程序，或其他用户访问内容历史信息。
一些实施例中，“项目”可显示图像缩略图。如：当项目为电影或电视剧时，项目可显示为电影或电视剧的海报。如项目为音乐时，可显示音乐专辑的海报。如项目为应用程序时，可显示为应用程序的图标，或当应用程序被执行最近执行时捕捉到应用程序的内容截图。如项目为用户访问历史时，可显示为最近执行过程中内容截图。“项目”可显示为视频剪辑。如：项目为电视或电视剧的预告片的视频剪 辑动态画面。
此外，项目可以表示显示设备200与外接设备连接的接口或接口集合显示，或可表示连接至显示设备的外部设备名称等。如：信号源输入接口集合、或HDMI接口、USB接口、PC端子接口等。
“选择器”用于指示其中任意项目已被选择，如:光标或焦点对象。根据用户通过控制装置100上输入，控制在显示设备200上光标移动来选择或控制项目。可根据用户通过控制装置100的输入，可使显示设备200中显示焦点对象的移动来选择控制项目，可选择或控制其中一个或多个项目。如：用户可通过控制装置100上方向键控制焦点对象在项目之间的移动来选择和控制项目。
示例性地，图8为本申请根据一示例性实施例示出的遥控器按键示意图。如图7所示，遥控器上仅具有“音量+”、“音量-”、“向上”、“向下”、“确认OK”“语音”、“返回”、“主页”以及“开/关”按键，其中，每个按键对应一个固有的控制功能，即其原生功能。例如，“音量+”的原生功能是提升音量，“向上”的原生功能是向上移动焦点。
随着显示设备业务场景、所安装软件应用、系统功能的增多，同时，随着以遥控器为主的控制装置趋向极简化、小巧化的设计趋势，遥控器上的按键数量及其原生功能，已难以满足各类场景中对显示设备的控制需求。
有鉴于此，在一些实施例中，显示设备的控制器响应于前台界面由第一界面成功切换到第二界面，获取第二界面的界面属性，界面属性用于表征界面是否复用遥控器按键；在第二界面的界面属性表征第二界面复用遥控器按键时，根据第二界面所复用的按键更新按键复用策略，按键复用策略中被复用的按键的按键状态为复用状态，未被复用的按键的按键状态为原生状态；响应于接收到遥控器的按键输入事件，根据更新后的按键复用策略确定按键输入事件对应的按键状态；响应于确定按键输入事件对应于复用状态，实现指示应用执行按键输入事件对应的复用功能。
在一些示例性的实施方式中，响应于确定案件输入事件对应复用状态，发送包含案件输入事件的定制化广播，其中，该定制化广播于用于指示应用执行案件输入事件对应的复用功能。
具体实现中，显示设备可根据其所处的应用状态，或者所在界面，复用任意遥控器上的按键。
在一些示例性的实施方式中，对遥控器上按键复用时，显示设备接收到的遥控器发出的键值的不区分应用和界面的，只是显示设备在接收后，根据其所处的应用或者界面解析成不同的命令。
在一些示例性的实施方式中，显示设备对音量键复用。显示设备在非摄像头相关的应用下，呈现非摄像头相关的用户界面，如呈现视频播放的界面，在该界面下用户触发音量键，如“音量+”或者“音量-”，实现对整机音量的增大(或减小)的功能。而当用户触发进入摄像头相关的应用时，显示器呈现摄像头相关的用户界面，如呈现摄像头采集的图像数据，在该界面下，用户触发同样的上述音量键，实现对摄像头焦距的放大(或缩小)，以在显示器上呈现与摄像头焦距相匹配的第二图像数据；或者实现摄像头焦距保持不变而是对呈现画面的放大(或缩小)。当用户退出该摄像头相关的应用进入视频播放类的应用时，解除对音量键的复用，触发音量键实现对整机音量的增大(或减小)的功能。
其中，非摄像头相关的应用包括视频播放相关应用和音乐播放相关应用，如点播应用，直播应用等。摄像头相关的应用包括上文提到的照镜子应用，录屏应用等。
一些实施例中，在摄像头相关界面中，图像全屏显示，如图11a。在该场景中，音量键对应摄像头焦距的调整。具体的，“音量-”对应摄像头焦距减小，“音量+”对应摄像头焦距放大。当用户在遥控器上触发“音量-”时，呈现图11b的画面。如图11b所示，摄像头焦距变小，获取的图像数据范围更大，在显示器上呈现比之前较大范围的图像数据，画面右侧出现画面大小调整条，提示用户当前处于0.5倍焦距的状态。当用户触发“音量+”时，呈现图11c所示的画面。如图11c所示，摄像头焦距变大，获取的图像范围变小，在显示器上呈现比之前较大范围的图像数据，画面右侧出现画面大小调整条，提示用户当前处于1.5倍或者更大焦距的状态。
另一些实施例中，在摄像头相关界面中，图片全屏显示，呈现图11a的画面。在该场景中，音量键对应预览画面的缩放调整。具体的，“音量-”对应预览图片缩小，“音量+”对应预览画面图片放大。当用户在遥控器上触发“音量-”时，如图11d所示，图像缩小为原全屏画面的0.5倍，画面右侧出现画面大小调整条，提示用户当前处于画面缩小0.5倍的状态。当用户按“音量+”至“1.0×”时，图片回到全屏显示状态。当用户在按“音量+”至“2.0×”时，图像当大至原图片的2倍，显示器上呈现图片的局部部分，画面右侧出现画面大小调整条，提示用户当前处于画面放大2倍的状态。
在上一实施例的另一种实施方式中，当用户在按“音量+”至“2.0×”时，图像当大至原图片的2倍，显示器上呈现图片的局部部分，画面右侧出现画面大小调整条，提示用户当前处于画面放大2倍的状态。另外，在显示器上呈现放大区域选择栏，可以通过遥控器上下左右的方向键实现对局部图像的锁定浏览，如图11f所示。
由于上述实施例将每个应用界面是否需要复用按键以及复用的按键集中保存在系统中，并根据前台界面是否需要复用按键以及复用的按键对按键复用策略进行即时更新，当接收到按键输入事件时，根据最新的按键复用策略，对转发按键输入事件进行集中控制，不仅能够实现遥控器上任意按键在任意应用界面下的复用，还可以保证复用按键的可靠性。
本申请实施例还提供一种遥控器按键复用方法，显示设备的控制器被配置为执行该方法的部分或者全部步骤，通过该方法，可以在预定的场景中，实现特定遥控器按键的复用，可靠性高，使遥控器可以对显示设备进行灵活多样的控制。
图9为本申请根据一示例性实施例示出的遥控器按键复用方法流程图。如图9所示，该方法可以包括：
步骤901，响应于前台界面由第一界面成功切换到第二界面，获取所述第二界面的界面属性，所述界面属性用于表征界面是否复用遥控器按键。
显示设备开机后，呈现用户界面，所呈现的用户界面中，可以仅包括一个应用的应用界面，此时，该应用界面在显示器屏幕上全屏显示，也可以包括多个应用的应用界面，此时，其中至少一个应用的应用界面以小于显示屏幕尺寸的窗口界面进行显示。
显示设备所呈现的一个或多个应用界面中，可以获取到遥控器信号焦点的界面为前台界面，前台界面所属的应用为前台应用。
示例性地，图10a为用户在应用中心打开“拍照应用”后进入的应用界面。如图10a所示，该显示设备用户界面中，仅包括一个应用界面，该应用界面可以获取到遥控器信号焦点，为前台界面。
另一示例性地，图10b为本申请根据一示例性实施例示出的另一用户界面，包括两个应用界面，其中，A界面以窗口形式浮于B界面显示，B界面作为背景界面在显示器上全屏显示，A界面可以获取到遥控器信号焦点，属于前台界面。
基于用户操作，在前台显示的应用界面可以发生切换。例如，参阅图10b，当用户通过遥控器将焦点位置由A界面移动到B界面时，前台界面由A界面切换至B界面。再如，继续参阅图10b，当用户通过遥控器选择A界面中的某一功能图标而进入A界面所属应用的另一界面C(图中未示出)时，前台界面由A界面切换至C界面。
在步骤901中，系统监测前台界面是否切换成功。通常，前台界面的切换过程包括：应用向系统发送将第一界面退出前台界面的请求；系统接收该请求后，向应用发送响应消息；应用接收到响应消息时，将第一界面从前台界面退出；应用向系 统发送将第二界面在前台界面显示的请求；系统接收该请求后，向应用发送响应消息；应用接收到响应消息时，将第二界面在前台界面显示。鉴于此，当系统监测到第二界面成功在前台界面显示时，确定前台界面由第一界面成功切换到第二界面。
需要说明的是，第一界面和第二界面可以为同一应用的两个不同界面，也可以是分别属于不同应用的界面。
在步骤901中，当系统监测到前台界面由第一界面成功切换到第二界面时，获取第二界面的界面属性。
本实施例中，界面可以有两种属性，例如第一属性和第二属性，分别用于表征需要复用按键和不需要复用按键。界面也可以在同一属性下具有两种取值，分别用于表征需要复用按键和不需要复用按键。为了便于说明，本申请将需要复用按键的界面称为客制化界面，将不需要复用按键的界面称为正常界面。
具体实现时，可以预先建立一个界面属性表，如.xml表格，用于对应保存应用和/或应用界面的包名名称和应用和/或应用界面的应用属性和/或界面属性，此外，对于客制化应用/界面，该.xml表格中还可以保存客制化应用/界面需要复用的按键，其中按键可以以键值来表示。
示例性地，.xml表格中数据保存格式可以为，<应用/应用界面包名-应用/界面属性-复用按键键值>。其中，根据应用/界面属性可以判定某一应用/应用界面是为客制化界面，或为正常界面，若为客制化界面，根据复用按键键值可以确定该应用/应用界面所复用的按键。
当显示设备启动后，将上述.xml表格数据读取到系统框架存储的H_MAP表格中。进而，在步骤901中，当监测到前台界面由第一界面成功切换至第二界面时，获取第二界面的界面名称，即其包名，然后在H_MAP表格中查找界面名称对应的界面属性。
步骤902，在所述第二界面的界面属性表征第二界面复用遥控器按键时，根据所述第二界面所复用的按键更新按键复用策略，所述按键复用策略中被复用的按键的按键状态为复用状态，未被复用的按键的按键状态为原生状态。
按键复用策略预置在操作系统中，按键复用策略中包括遥控器上每个按键的按键状态，按键状态包括原生状态和复用状态。对于某一按键，如果根据按键复用策略确定其处于原生状态，则表示该按键未被复用，如果根据按键复用策略确定其处于复用状态，则表示该按键被复用。
在本实施例中，第二界面可能为客制化界面，也可能为正常界面，在所述第二界面的界面属性表征第二界面复用遥控器按键时，根据所述第二界面所复用的按键 更新按键复用策略。
具体实现时，首先根据第二界面的界面属性判断第二界面是否为需要复用按键的预设界面。例如，如果第二界面的界面属性值为预定值，则第二界面为预设界面，如果第二界面的界面属性值非预定值，则第二界面非预设界面，即不需要复用按键。
如果第二界面是预设界面，则获取第二界面所复用的按键。需要说明的是，诸如第二界面的任意预设界面所复用的按键，均为预定，并且预先保存在上述界面属性列表中。基于此，如果第二界面是预设界面，则在上述H_MAP表格中，可以查找到其所复用按键的键值。然后，将所述按键复用策略中所述第二界面所复用按键的按键状态更新为复用状态，其余按键的按键状态更新为原生状态。
如果第二界面非预设界面，则将所述按键复用策略中每一按键的按键状态更新为原生状态。
步骤903，响应于接收到遥控器的按键输入事件，根据更新后的按键复用策略确定所述按键输入事件对应的按键状态。
在本申请场景中，如果用户使用遥控器操作显示设备，显示设备会接收到按键输入事件，并获取到按键输入事件对应的按键键值。当接收到遥控器的按键输入事件时，在步骤903中，根据按键输入事件对应的按键键值，在更新后的按键复用策略中，可以查找到该按键键值对应的按键状态，是为原生状态，或为复用状态。
在步骤904中，响应于确定所述按键输入事件对应于所述复用状态，发送包含所述按键输入事件的定制化广播，所述定制化广播用于指示应用执行所述按键输入事件对应的复用功能。
或者，相应地，响应于确定所述按键输入事件对应于所述原生状态，则通过系统线程与UI线程之间的线程间通信，将该按键输入事件发送给应用层。
例如，假设第二界面为图10a所示的应用界面，该应用界面预定的复用按键为“音量+”，那么，在界面属性列表中，该应用界面的界面名称对应的界面属性的属性值为预定值，对应的复用按键键值为“音量+”的键值。当该应用界面成功在前台界面显示时，系统将按键复用策略中“音量+”的按键状态修改为复用状态，其余按键的按键状态均为原生状态。当系统接收到按键输入事件时，如果为“音量+”的按键输入，则发送包含该按键输入事件的广播。图10a所示应用界面所属的应用接收到该广播后，执行广播中该按键输入事件对应的处理逻辑。
由上述实施例可知，本申请实施例提供一种遥控器按键复用方法，应用于显示设备控制器，响应于前台界面由第一界面成功切换到第二界面，获取第二界面的界面属性，；在第二界面的界面属性表征第二界面复用遥控器按键时，根据第二界面 所复用的按键更新按键复用策略；响应于接收到遥控器的按键输入事件，根据更新后的按键复用策略确定按键输入事件对应的按键状态；响应于确定按键输入事件对应于复用状态，发送包含按键输入事件的定制化广播，该定制化广播用于指示应用执行所述按键输入事件对应的复用功能。
由于本申请方法将每个应用界面是否需要复用按键以及复用的具体按键集中保存在系统中，并通过按键复用策略，对转发按键输入事件进行集中控制，不仅能够实现遥控器上任意按键在任意应用界面下的复用，还可以保证复用按键的可靠性。
图11为本申请根据一示例性实施例示出的在“相册”应用中，复用遥控器上“音量+”和“音量-”按键的场景。在该场景中，“相册”应用为前台应用，图11所呈现的应用界面为预设界面，即客制化界面，在该界面下，用户可以通过按压遥控器上的“音量+”和“音量-”，放大或缩小正在查看的图片，“音量+”和“音量-”的放大或缩小正在查看的图片的功能，即为“音量+”和“音量-”的复用功能。
另外，为了提高用户体验的友好度，在本申请另外的实施例中，上述步骤902之后，还包括：响应于按键复用策略中至少一个按键的按键状态被更新为复用状态，生成提示信息，所述提示信息用于提示用户当前已复用的遥控器按键；将所述提示信息在前台界面上显示。
为了进一步提高遥控器按键的可靠性，在上述实施例基础上，本申请还提供以下实施例，如图12所示，在该实施例中，遥控器按键复用方法包括：
步骤121，接收用于将前台界面由第一界面切换到第二界面的请求。
需要说明的是，步骤121所述的请求，可以为两个请求，其一为用于将第一界面从前台界面退出的请求，其二为用于将第二界面从前台界面显示的请求。
步骤122，更新所述按键复用策略为默认策略，所述默认策略中任意按键输入事件对应的按键状态均为原生状态；
步骤123，将所述第一界面从前台界面退出；
步骤124，将所述第二界面在前台界面显示；
步骤125，获取所述第二界面的界面属性；
步骤126，根据所述第二界面的界面属性，更新按键复用策略；
步骤127，当接收到遥控器的按键输入事件时，根据更新后的按键复用策略，确定所述按键输入事件对应的按键状态；
步骤128，如果所述按键输入事件对应的按键状态为复用状态，则发送包含所述按键输入事件的定制化广播，所述定制化广播用于指示应用执行所述按键输入事件对应的复用功能。
在图12所示实施例中，由于切换前台界面的过程中(步骤121之后，步骤124之前)，将按键复用策略更新为默认策略，从而保证一旦退出客制化界面，就使遥控器按键恢复到原生状态，避免在切换前台界面的时间里，由于某一些按键仍然处于复用状态而导致这些按键失效。
在图12所示实施例中，由于第一界面和第二界面属于同一应用的不同界面，因此在切换前台界面的过程中不涉及前台应用切换。基于此，在本申请的另外的实施例中，如果第一界面和第二界面分别属于不同的应用，那么，在当系统接收用于将前台应用由第一应用切换到第二应用的请求时，先行将按键复用策略更新为默认策略，然后再将第一应用从前台应用退出，将所述第二应用在前台界面运行。从而，能够保证一旦前台应用退出，就使遥控器按键恢复到原生状态，避免在切换前台应用的时间里，由于某一些按键仍然处于复用状态而导致这些按键失效。
在一些场景中，前台应用可能出现诸如内存泄露、无响应、无法获取焦点等异常，此时，如果存在按键状态为复用状态的按键，则在应用被系统停止之前，处于复用状态的按键将无法实现其原生功能。例如，处于前台的“拍照应用”出现无响应，若“音量+”为该“拍照应用”复用的按键，则在“拍照应用”无响应的时间里，用户将无法使用“音量+”按键开调节显示设备的输出音量。
为了解决该问题，在本申请另外的实施例中，显示设备在执行以上实施例所提供步骤的同时，还执行：
检测前台应用是否异常；
如果检测到前台应用异常，更新所述按键复用策略为默认策略。
进而，在前台应用出现异常到其被系统关闭的时间里，可以保证任意按键均能实现其原生功能，从而提高按键可靠性。
由上述实施例可知，本申请提供一种遥控器按键复用方法：
当接收到将前台界面由第一界面切换到第二界面的请求时，更新按键复用策略为默认策略，从而保证在界面切换过程中，遥控器按键可以实现其原生功能，提高按键可靠性。
当前台界面由第一界面成功切换到第二界面时，根据所述第二界面的界面属性，更新预置的按键复用策略；当接收到遥控器的按键输入事件时，根据更新后的按键复用策略，确定所述按键输入事件对应的按键状态，所述按键状态包括原生状态和复用状态；如果所述按键输入事件对应的按键状态为复用状态，则发送包含所述按键输入事件的广播，从而实现遥控器上任意按键在任意应用界面下的复用。
当检测到前台应用异常时，更新所述按键复用策略为默认策略，进而，在前台 应用出现异常到其被系统关闭的时间里，可以保证任意按键均能实现其原生功能，从而提高按键可靠性。
具体实现中，本申请还提供一种计算机存储介质，其中，该计算机存储介质可存储有程序，该程序执行时可包括本申请提供的方法的各实施例中的部分或全部步骤。所述的存储介质可为磁碟、光盘、只读存储记忆体(英文：read-only memory，简称：ROM)或随机存储记忆体(英文：random access memory，简称：RAM)等。
本领域的技术人员可以清楚地了解到本申请实施例中的技术可借助软件加必需的通用硬件平台的方式来实现。基于这样的理解，本申请实施例中的实现方式本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品可以存储在存储介质中，如ROM/RAM、磁碟、光盘等，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本申请各个实施例或者实施例的某些部分所述的方法。
本说明书中各个实施例之间相同相似的部分互相参见即可。尤其，对于显示设备实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例中的说明即可。
以上所述的本申请实施方式并不构成对本申请保护范围的限定。本领域的技术人员可以清楚地了解到本申请实施例中的技术可借助软件加必需的通用硬件平台的方式来实现。基于这样的理解，本申请实施例中的实现方式本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品可以存储在存储介质中，如ROM/RAM、磁碟、光盘等，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本申请各个实施例或者实施例的某些部分所述的方法。
