Description

显示设备及应用共同显示的方法
本公开要求在2019年6月10日提交中国专利局、申请日为201910498564.5、申请名称为“双系统间应用共同显示的方法、系统及显示设备”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本申请涉及智能电视技术领域，尤其涉及一种显示设备及应用共同显示的方法。
背景技术
智能电视可提供数个不同的应用，例如电视、应用软件、视频点播(video on demand，VOD)、媒体中心等。并且随着技术的不断发展，智能电视所提供的应用也越来越多。
智能电视采用全屏幕悬浮式主页界面的交互系统，该交互系统可以在应用程序界面的上层悬浮显示主页界面。使用该交互系统的智能电视开机后，会先显示空白的载体界面，再显示非透明的应用程序界面，由于载体界面所在的第一窗口与该应用程序界面所在的第二窗口层级相同，生成时刻晚点第二窗口位于生成时刻早的第一窗口之上显示，因此该应用程序界面将覆盖显示在载体界面之上。当智能电视接收到用户利用遥控器发送的用于打开主页界面的打开指令时，会打开悬浮窗口，在该悬浮窗口中显示主页界面的主页界面对象，使得主页界面悬浮显示，由于悬浮窗口的窗口层级高于该应用程序界面所在的第二窗口的窗口层级，因此打开后的主页界面会悬浮显示在该应用程序界面的上层。
但是，针对具有社交功能的双系统电视，例如，主系统N提供电视业务，辅系统A提供交互及运营业务，两个系统只有一个屏幕，由主系统N控制，对于Android系统来说，每个系统都有自己的主页，两个系统同时响应主页键时，会把两个系统的主页同时拉起来，影响主页的显示和协调，导致用户体验下降。
发明内容
本申请提供了一种显示设备及应用共同显示的方法，以实现社交电视两个主页共存、两个系统各自应用协调显示。
为了解决上述技术问题，本申请实施例公开了如下技术方案：
第一方面，本申请实施例公开了一种显示设备，包括：
显示器，被配置为显示图像内容；
第一控制器，被配置为获取显示指令，并判断所述显示指令显示的应用是否位于所述第一控制器；
第二控制器，被配置为接收所述第一控制器输出的所述显示指令，并根据所述显示指令显示应用界面；
其中，若所述显示指令显示的应用位于所述第一控制器，则直接显示应用界面，将所述应用界面与所述第二控制器的显示界面层叠显示；若所述显示指令显示的应用位于所述第二控制器，则所述第一控制器将其主页切换至透明主页，通知所述第二控制器显示应用界面，并切换信号源通道，将所述透明主页与所述第二控制器的应用显示界面层叠显示。
第二方面，本申请实施例还提供了一种应用共同显示的方法，应用于第一方面所述的显示设备，所述方法包括：
第一控制器获取显示指令，并判断所述显示指令显示的应用是否位于所述第一控制器；
若所述显示指令显示的应用位于所述第一控制器，则所述第一控制器直接显示应用界面，并将所述应用界面与第二控制器的显示界面层叠显示；
若所述显示指令显示的应用不位于所述第一控制器，则所述第一控制器将其主页切换至透明主页，通知所述第二控制器显示应用界面，并切换信号源通道，将所述透明主页与所述第二控制器的应用显示界面层叠显示。

具体实施方式
为使本申请示例性实施例的目的、技术方案和优点更加清楚，下面将结合本申请示例性实施例中的附图，对本申请示例性实施例中的技术方案进行清楚、完整地描述，显然，所描述的示例性实施例仅是本申请一部分实施例，而不是全部的实施例。
本申请涉及的显示终端包含至少两个系统级控制器芯片，为了便于理解，在此，对多芯片控制器，尤其是双控制器结构的显示终端进行介绍。
为便于用户使用，显示设备上通常会设置各种外部装置接口，以便于连接不同的外设设备或线缆以实现相应的功能。而在显示设备的接口上连接有高清晰度的摄像头时，如果显示设备的硬件系统没有接收源码的高像素摄像头的硬件接口，那么就会导致无法将摄像头接收到的数据呈现到显示设备的显示屏上。
并且，受制于硬件结构，传统显示设备的硬件系统仅支持一路硬解码资源，且通常最大仅能支持4K分辨率的视频解码，因此当要实现边观看网络电视边进行视频聊天时，为了不降低网络视频画面清晰度，就需要使用硬解码资源(通常是硬件系统中的GPU)对网络视频进行解码，而在此情况下，只能采取由硬件系统中的通用处理器(例如CPU)对视频进行软解码的方式处理视频聊天画面。
采用软解码处理视频聊天画面，会大大增加CPU的数据处理负担，当CPU的数据处理负担过重时，可能会出现画面卡顿或者不流畅的问题。进一步的， 受制于CPU的数据处理能力，当采用CPU软解码处理视频聊天画面时，通常无法实现多路视频通话，当用户想要再同一聊天场景同时与多个其他用户进行视频聊天时，会出现接入受阻的情况。
基于上述各方面的考虑，为克服上述缺陷，本申请公开了一种双硬件系统架构，以实现多路视频聊天数据(至少一路本地视频)。
下面首先结合附图对本申请所涉及的概念进行说明。在此需要指出的是，以下对各个概念的说明，仅为了使本申请的内容更加容易理解，并不表示对本申请保护范围的限定。

本申请各实施例中使用的术语“手势”，是指用户通过一种手型的变化或手部运动等动作，用于表达预期想法、动作、目的/或结果的用户行为。
本申请各实施例中使用的术语“硬件系统”，可以是指由集成电路(Integrated Circuit，IC)、印刷电路板(Printed circuit board，PCB)等机械、光、电、磁器件构成的具有计算、控制、存储、输入和输出功能的实体部件。在本申请各个实施例中，硬件系统通常也会被称为主板(motherboard)或芯片。

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。
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芯片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。
在Android电视设备上，针对双系统的新形态，我们希望同时将两个系统的能力展示给用户。第一控制器(A芯片)可以相应按键、设置，主要是展示电视功能，第二控制器(N芯片)主要展示给用户社交能力，第一控制器可通过网络、串口、Tybe-C线和HDMI通信方式等具有数据和通信交互的连接方式连接第二控制器。如第二控制器有HDMI OUT通路，第一控制器与第二控制器通过HDMI连接，硬件上类似于电视第一控制器外接了一个机顶盒。如图8所示，第二控制器的显示内容通过HDMI OUT向第一控制器传递图像，在第一控制器上，第二控制器就是一路HDMI输入，第二控制器的HDMI信号接入第一控制器的HDMI4口。
但是第一控制器只提供电视能力，有视频点播和资讯入口的主页在第二控 制器上，我们需要在用户按主页键时，将第二控制器的内容显示出来，并且第二控制器跳转到主页。双系统之间的按键传递是另外一个模块，此处不再赘述，默认按键可以传递过去。由于第一控制器也有一个主页，两个系统同时相应主页键，会把两个系统的主页同时拉起来，因此这里存在两个问题：一是如何将两个主页共存，视觉上只显示一个主页；二是如何协调两个系统各自应用显示的关系。
为了解决上述问题，本申请实施例提供了一种显示设备，该显示设备将第一控制器的主页设置为透明主页，通过该透明主页与应用显示界面的层叠显示，可实现双系统的双主页的显示和协调、双系统中各自应用的显示和协调。
如图9所示，本申请实施例提供的显示设备包括：
第一控制器101，被配置为获取显示指令，并判断显示指令显示的应用是否位于第一控制器。
第二控制器201，被配置为通过物理连接线接收第一控制器输出的显示指令，并根据显示指令显示应用界面。
其中，若显示指令显示的应用位于第一控制器，则直接显示应用界面，将应用界面与第二控制器的显示界面层叠显示；若显示指令显示的应用位于第二控制器，则第一控制器将其主页切换至透明主页，通知第二控制器显示应用界面，并切换信号源通道，并透明主页与第二控制器的应用显示界面层叠显示。
显示器301，被配置为显示图像内容。
其中，为了描述方便，图4与图5中的处理器310与图9中的第一控制器101对应，图4和图5中的处理器210与图9中的第二控制器201对应，以下不再指出。
本示例中，第一控制器101包括获取模块101-1与控制模块101-2，获取模块101-1用于获取显示指令。即用户可通过遥控器按键发送显示指令，获取模块101-1接收用户发送的显示指令。如用户按键主页键，即要显示主页；用户按键应用打开，即要打开某一系统的应用。
第一控制器101的获取模块101-1获得显示指令时，该显示指令可为显示主页，也可为显示第一控制器应用，也可为显示第二控制器应用，由于视频点播和资讯入口的主页在第二控制器上，当用户按主页键时，希望显示第二控制器的主页，因此通过判断显示指令显示的应用是否位于第一控制器来区分应用位于第二控制器还是位于第一控制器。
控制模块101-2根据接收的显示指令来判断显示的应用是位于第一控制器101还是位于第二控制器201，并对此执行不同的控制指令。
如确定要显示的应用位于第二控制器时，即用户想要看到第二控制器的应用显示界面，需要将第一控制器的主页切换至透明主页，透过该透明主页显示第二控制器的应用显示界面。第二控制器的应用显示界面可能为主页界面，也可能为应用显示界面。
用户按下主页按键，即显示指令为主页显示指令时，第一控制器将其主页切换至透明主页，即透过该透明主页可看到第二控制器的界面；然后第一控制器通知第二控制器切换至主页界面，即通知第二控制器拉起主页或将主页切换至前台；然后第一控制器切换第一控制器的信号源通道为相应的HDMI通道，即将第二控制器的显示内容向第一控制器传递图像。此时，第一控制器的透明主页与第二控制器的主页界面层叠显示，且透明主页在前方，第二控制器的主页界面在后方，由于第一控制器的主页为透明主页，第二控制器的主页界面可 透过该透明主页进行显示，用户看到的就是第二控制器的主页内容。
用户在主页下按控制键(上下左右OK等)时，即系统显示的还是主页界面，但通过遥控器对主页界面进行上、下、左、右等操作时，首先将控制键信息发送至第一控制器的透明主页，透明主页接收到控制键信息后将该控制键信息转发至第二控制器，第二控制器接收第一控制器转发的控制键信息，并将其直接发给主页，主页界面根据该控制键信息进行上、下、左、右浏览操作。由于第一控制器的主页为透明主页，虽然实际是操作第一控制器，但从用户角度来看与直接操作第二控制器主页一致，提升了用户的使用体验。
用户想打开第二控制器上的某一应用，即显示指令为第二控制器应用显示指令时，第一控制器将其主页切换至透明主页，然后第一控制器通知第二控制器启动应用，第二控制器的主页被切换至应用显示界面的后方，然后第一控制器切换第一控制器的信号源通道为相应的HDMI通道，将第二控制器的应用内容向第一控制器传递图像。此时，第一控制器的透明主页与应用显示界面层叠显示，且透明主页在前方，第二控制器的应用显示界面在后方，第二控制器的应用显示界面可透过透明主页进行显示，用户看到的就是第二控制器的应用显示界面。
第二控制器的应用在显示应用界面时，可能为全屏显示，也可能为非全屏显示，如启动第二控制器端的爱奇艺App时，用户一般希望爱奇艺App的应用显示界面为全屏显示，此时需要将第一控制器的主页切换至透明主页，该透明主页与爱奇艺应用显示界面层叠显示，爱奇艺应用显示界面可透过透明主页在第一控制器上显示，实现爱奇艺App的全屏显示。
第二控制器的应用显示界面为非全屏时，如启动第二控制器端的视频聊天 应用，聊天窗口只占用屏幕的一部分，可将第一控制器的主页切换至部分透明主页，部分透明主页与非全屏应用显示界面层叠显示，即部分透明主页在前方，非全屏应用显示界面在后方，非全屏应用显示界面透过部分透明主页的透明部分进行显示，同时，部分透明主页的非透明部分可显示第一控制器主页的部分内容，实现多种功能显示。
对于第二控制器的应用显示界面为非全屏时，也可将第一控制器的主页切换至透明主页，透明主页、非全屏应用显示界面与第二控制器主页层叠显示，即透明主页在前方，非全屏应用显示界面在中间，第二控制器主页在后方，如此，非全屏应用显示界面的内容与未被非全屏应用显示界面遮挡的主页内容可同时显示，实现多种功能显示。
如确定要显示的应用位于第一控制器时，即用户想要看到第一控制器的应用显示界面，则第一控制器直接启动应用，显示应用显示界面。启动第一控制器应用时，就是在第二控制器主页上启动第一控制器应用，而该应用界面可能为全屏应用显示界面，也可能为非全屏应用显示界面。
对于第一控制器上全屏应用显示界面的应用，通知第一控制器启动应用，切走第一控制器的HDMI通道，防止第二控制器上应用的声音等传递至第一控制器上。此场景下，应用全屏显示界面、第一控制器主页与第二控制器应用显示界面层叠显示，应用全屏显示界面在前方，第一控制器主页在中间，第二控制器应用显示界面在后方，第一控制器上的应用内容直接在屏幕上显示。该场景中，由于应用全屏显示界面将第一控制器主页遮挡住，因此第一控制器主页可为透明主页，也可为非透明主页。
对于第一控制器上非全屏应用显示界面的应用，通知第一控制器启动应用， 将第一控制器的主页切换至透明主页，将非全屏应用显示界面、透明主页与第二控制器的显示界面层叠显示。此场景下，第一控制器的非全屏应用显示界面在前方，第一控制器主页在空间，第二控制器应用显示界面在后方，第一控制器上的应用内容在屏幕上部分显示，同时第二控制器上的显示界面可部分显示，如此，非全屏应用显示界面的内容与未被非全屏应用显示界面遮挡的第二控制器的显示内容可同时显示，实现多种功能显示。该场景中，由于非应用全屏显示界面未将第一控制器主页遮挡住，因此第一控制器主页为透明主页。
针对双系统电视，双系统的双主页显示和协调、双系统中各自应用的显示和协调具有各种场景，而各场景下双主页功能处理如下表所示：
场景第一控制器第二控制器
按主页键切换至主页通知第二控制器拉起主页，自己切换至透明主页，切换至相应HDMI通道拉起主页或将主页切换至前台。
在主页下按控制键(上下左右OK等)透明主页收到按键后，键转发至第二控制器，因主、第二控制器都在主页状态，从用户角度来看与直接操作第二控制器主页一致。接收到第一控制器转发来的按键并直接发给主页。
进入第二控制器主页应用中心将第一控制器中的应用列表并发给第二控制器。1、显示本地安装的应用。
2、获取并显示第一控制器安装的应用。
在第二控制器上操作启动第一控制器全屏应用 启动应用，并将通道切走。(防止第二控制器的声音传递到第一控制器)通知第一控制器启动应用。
在第二控制器上操作启动第一控制器非全屏应用 启动应用，保持当前通道，保持当前透明主页在后方。通知第一控制器启动应用。
从第一控制器全屏应用返回主页。返回透明主页，切换至第二控制器所在的HDMI通道，通知第二控制器拉起主页。拉起主页或将主页切换至前台。
针对用户按主页键切换至主页的场景，由于第一控制器只提供电视能力，有视频点播和资讯入口的主页在第二控制器上，因此用户按主页键想要看到的是第二控制器的主页，此时第一控制器通知第二控制器拉起主页，并将自身的主页切换至透明主页，切换信号源至相应HDMI通道，而第二控制器拉起主页或将主页切换至前台，通过HDMI通道显示第二控制器主页界面。此场景中，第一控制器的透明主页与第二控制器的主页界面层叠显示，第二控制器的主页界面透过第一控制器的透明主页显示，使得用户按主页键看到的是第二控制器的主页界面。
针对用户在主页下按控制键(上下左右OK等)的场景，第一控制器的透明主页接收到按键信息后，将按键信息转发至第二控制器，第二控制器接收到第一控制器转发来的按键信息后，直接将按键信息发给主页，执行相应的按键操作，因此时主、第二控制器均处在主页状态，因此从用户角度来看与直接操作第二控制器主页一致。
针对进入第二控制器主页应用中心的场景，双系统电视打开时显示的是第二控制器的主页，为方便启动第一控制器与第二控制器上的应用，在第二控制器的应用中心同时显示第一控制器与第二控制器的应用，即将第一控制器中的应用列表并发给第二控制器，第二控制器的主页获取并显示第一控制器安装的应用，同时显示第二控制器本地安装的应用。
针对在第二控制器上操作启动第一控制器全屏应用的场景，第二控制器通知第一控制器启动应用，而第一控制器启动该应用，并将HDMI通道切走，以 防止第二控制器的声音传递到第一控制器。此场景中，第一控制器的全屏应用界面与第二控制器的显示界面层叠显示，用户只看到第一控制器的全屏应用界面。
针对在第二控制器上操作启动第一控制器非全屏应用的场景，对于第一控制器上非全屏应用显示界面的应用，如某种对话框等，第二控制器通知第一控制器启动应用，将第一控制器的主页切换至透明主页，保持当前信号源HDMI通道。此场景下，非全屏应用显示界面、透明主页与第二控制器应用显示界面层叠显示，非全屏应用显示界面在前，透明主页在中间，第二控制器应用显示界面在后方，第一控制器上的非全屏应用内容直接在屏幕上显示，未被非全屏应用显示界面遮挡的第二控制器应用显示界面也可在第一控制器屏幕上显示，实现多功能显示。
针对从第一控制器全屏应用返回主页的场景，用户启动第一控制器上的全屏应用后，想返回主页，该场景下，会将第一控制器的主页切换至透明主页，通知第二控制器拉起主页或将主页切换至前台，然后将系统信号源切换至HDMI通道，第二控制器主页内容通过HDMI OUT向第一控制器传递图像，在第一控制器屏幕上显示第二控制器的主页。此场景下，透明主页与第二控制器主页层叠显示，透明主页在前，第二控制器主页在后，第二控制器主页内容透过该透明主页进行显示。
本申请实施例提供的显示设备将第一控制器的主页做成透明主页，当用户按下主页键时，将第一控制器主页切换至透明主页，第一控制器通知第二控制器拉起主页或将主页切换至前台，并将第一控制器信号源切换至HDMI通道，此时透明主页与第二控制器主页层叠显示，第二控制器主页透过透明主页进行 显示，用户看到的就是第二控制器主页；当用户想打开第二控制器上的应用时，保留第一控制器的透明主页，第一控制器通知第二控制器启动应用，透明主页与第二控制器应用显示界面层叠显示，第二控制器应用内容通过HDMI通道传递至第一控制器，透过透明主页进行显示；当用户想打开第一控制器上的应用时，第二控制器通知第一控制器启动应用，切走第一控制器的HDMI通道，应用显示界面与第一控制器主页层叠显示，应用显示界面遮挡住第一控制器主页，直接在第一控制器屏幕上进行显示。本申请提供的显示设备借助透明主页实现了双系统主页和双系统内各自应用内容的显示和协调，让用户使用上感觉就是一个系统，大大提升了用户的使用体验。
基于上述实施例所述的显示设备，本申请实施例还提供了一种应用共同显示的方法，所述方法应用于上述实施例所述的显示设备。
如图10所示，本申请实施例提供的应用共同显示的方法包括：
S100：第一控制器获取显示指令。
S200：第一控制器判断显示指令显示的应用是否位于第一控制器。
S300：若显示指令显示的应用位于第一控制器，则第一控制器直接显示应用界面，并将应用界面与第二控制器的显示界面层叠显示。
S400：若显示指令显示的应用位于第二控制器，则第一控制器将其主页切换至透明主页，通知第二控制器显示应用界面，并切换信号源通道，将透明主页与第二控制器的应用显示界面层叠显示。
本申请实施例提供的应用共同显示的方法，通过第一控制器获取显示指令，并判断显示指令显示的应用是否位于第一控制器；若显示指令显示的应用位于第一控制器，则直接显示应用界面，将应用界面与第二控制器的显示界面层叠 显示；若显示指令显示的应用不位于第一控制器，即显示指令显示的应用位于第二控制器，则第一控制器将其主页切换至透明主页，通知第二控制器显示应用界面，第二控制器接收第一控制器输出的显示指令，并根据显示指令显示应用界面，同时第一控制器切换信号源通道，将透明主页与第二控制器的应用显示界面层叠显示。如此借助透明主页实现了双系统主页和双系统内应用内容的协调显示，让用户使用上感觉就是一个系统，从而大大提升了用户的使用体验。
具体实现中，本发明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发明提供的节目推送播放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。
