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。
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)。

第二控制器的图形处理器316与第一控制器的图形处理器216均能产生各种图形对象。区别性的，若应用1安装于A芯片，应用2安装在N芯片，当用户在应用1的界面，且在应用1内进行用户输入的指令时，由A芯片图形处理器316产生图形对象。当用户在应用2的界面，且在应用2内进行用户输入的指令时，由N芯片的图形处理器216产生图形对象。
图5中示例性示出了根据示例性实施例中显示设备的功能配置示意图。
如图5所示，A芯片的存储器390和N芯片的存储器290分别用于存储操作系统、应用程序、内容和用户数据等，在A芯片的控制器310和N芯片的控制器210的控制下执行驱动显示设备200的系统运行以及响应用户的各种操作。A芯片的存储器390和N芯片的存储器290可以包括易失性和/或非易失性存储器。
对于N芯片，存储器290，具体用于存储驱动显示设备200中控制器210的运行程序，以及存储显示设备200内置各种应用程序，以及用户从外部设备下载的各种应用程序、以及与应用程序相关的各种图形用户界面，以及与图形用户界面相关的各种对象，用户数据信息，以及各种支持应用程序的内部数据。存储器290用于存储操作系统(OS)内核、中间件和应用等系统软件，以及存储输入的视频数据和音频数据、及其他用户数据。

存储器390，包括存储用于驱动和控制显示设备200的各种软件模块。如：存储器390中存储的各种软件模块，包括：基础模块、检测模块、通信模块、显示控制模块、浏览器模块、和各种服务模块等。由于存储器390与存储器290 的功能比较相似，相关之处参见存储器290即可，在此就不再赘述。
示例的，存储器390，包括图像控制模块3904、音频控制模块2906、外部指令识别模块3907、通信控制模块3908、光接收模块3909、操作系统3911、以及其他应用程序3912、浏览器模块等等。控制器210通过运行存储器290中各种软件程序，来执行诸如：图像控制功能、显示控制功能、音频控制功能、外部指令识别功能、通信控制功能、光信号接收功能、电力控制功能、支持各种功能的软件操控平台、以及浏览器功能等各类功能。
区别性的，N芯片的外部指令识别模块2907和A芯片的外部指令识别模块3907可识别不同的指令。
示例性的，由于摄像头等图像接收设备与A芯片连接，因此，A芯片的外部指令识别模块3907可包括图形识别模块2907-1，图形识别模块3907-1内存储有图形数据库，摄像头接收到外界的图形指令时，与图形数据库中的指令进行对应关系，以对显示设备作出指令控制。而由于语音接收设备以及遥控器与N芯片连接，因此，N芯片的外部指令识别模块2907可包括语音识别模块2907-2，图形识别模块2907-2内存储有语音数据库，语音接收设备等接收到外界的语音指令或时，与语音数据库中的指令进行对应关系，以对显示设备作出指令控制。同样的，遥控器等控制装置100与N芯片连接，由按键指令识别模块与控制装置100进行指令交互。
图6a中示例性示出了根据示例性实施例中显示设备200中软件系统的配置框图。
对N芯片，如图6a中所示，操作系统2911，包括用于处理各种基础系统服务和用于实施硬件相关任务的执行操作软件，充当应用程序和硬件组件之间完成数据处理的媒介。
一些实施例中，部分操作系统内核可以包含一系列软件，用以管理显示设备硬件资源，并为其他程序或软件代码提供服务。
其他一些实施例中，部分操作系统内核可包含一个或多个设备驱动器，设备驱动器可以是操作系统中的一组软件代码，帮助操作或控制显示设备关联的设备或硬件。驱动器可以包含操作视频、音频和/或其他多媒体组件的代码。示例的，包括显示器、摄像头、Flash、WiFi和音频驱动器。
其中，可访问性模块2911-1，用于修改或访问应用程序，以实现应用程序的可访问性和对其显示内容的可操作性。

由于A芯片的操作系统3911与N芯片的操作系统2911的功能比较相似，相关之处参见操作系统2911即可，在此就不再赘述。
如图6b中所示，显示设备的应用程序层包含可在显示设备200执行的各种应用程序。
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，本发明无需对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，直播电视应用程序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。
如图7所示，A芯片(第二控制器)与N芯片(第一控制器)之间可以通过多个不同类型的接口实现连接、通信及供电。A芯片与N芯片之间接口的接口类型可以包括通用输入输出接口(General-purpose input/output，GPIO)、USB接口、HDMI接口、UART接口等。A芯片与N芯片之间可以使用这些接口中的一个或多个进行通信或电力传输。例如图7所示，在双硬件系统架构下，可以由外接的电源(power)为N芯片供电，而A芯片则可以不由外接电源，而由N芯片供电。
除用于与N芯片进行连接的接口之外，A芯片还可以包含用于连接其他设备或组件的接口，例如图7中所示的用于连接摄像头(Camera)的MIPI(mobile  industry processor interface)接口，蓝牙接口、USB接口等。
类似的，除用于与N芯片进行连接的接口之外，N芯片还可以包含用于连接显示屏TCON(Timer Control Register)的VBY接口，用于连接功率放大器(Amplifier，AMP)及扬声器(Speaker)的i2S接口；以及IR/Key接口，USB接口，Wifi接口，蓝牙接口，HDMI接口，Tuner接口等。
在一种实施例中，用户也可以边观看直播视频，边进行视频聊天。对于N芯片来说，其可通过图7所示的HDMI2.0外接机顶盒等提供直播电视的设备，因此，一般使用N芯片呈现直播视频。
而直播电视由机顶盒或广电方面直接解码，不需要占用N芯片的硬件解码资源，所以，在实现边进行观看直播电视边进行视频聊天时，可以由N芯片的硬件资源解码摄像头接收的数据。
在一种实施例中，用户可以进行边看网络视频，边进行视频聊天。在这种场景中，网络或第三方应用提供点播视频，该点播视频的数据需要硬件解码资源进行解码。而从摄像头接收的数据也需要硬件解码。所以如果想要实现边观看网络视频边进行视频聊天的应用场景，需要将摄像头接收的数据和网络视频资源分别在两个芯片上进行解码。
当摄像头接收的数据由N芯片进行硬件解码时，可以由A芯片对点播视频进行硬件解码。因此，应用程序的设置上，A芯片用于存储和运行第三方视频点播应用。如图7，A芯片与N芯片之间的HDMI线用于传输点播视频或者第三方应用的数据。其中，该HDMI线对用户不可见。另外，HDMI线仅作为可选的数据传输方式，但不限于用HDMI线进行数据传输。
因此，如图7所示的硬件建构可实现任一边看直播电视边进行视频聊天，还是边观看网络电视边进行视频聊天的场景中的其中一种，而A芯片和N芯片硬件解码能力均不受影响。
另外，如图7所示，A芯片与N芯片之间，而可以有USB线作为连接，该USB线用于将摄像头接收的视频数据传输至N芯片，以供硬件解码和在显示器上的呈现。当然，USB线仅仅是作为数据连接方式的一种实例，在A芯片和N芯片之间，也可以有另外可选的数据连接方式。在A芯片端接有摄像头，该A 芯片与摄像头的连接可以是通过MIPI接口，也可以是通过USB接口。
在边网络聊天边进行视频聊天的场景中，A芯片中的第三方视频应用的点播资源通过HDMI线传输至N芯片，最终呈现在显示器上。A芯片接收的摄像头的数据，通过USB线传输至N芯片，并通过解码以后，呈现在显示器上。
由于A芯片及N芯片中可以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。
需要说明的是，显示设备对多个HDMI数据择一显示。也就是说，当用户在HDMI2.0通道观看直播媒体播放内容时，不能通过另一个HDMI通道查看其他媒体播放内容。但是视频聊天内容由于不通过HDMI通道连接，所以，无论当前播放什么类型的媒体内容，均能够同时显示视频聊天内容。
图8a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8a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和第二视图显示区202，其中，第二视图显示区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应用程序的显示画面。如，第一视图显示区201可呈现视频聊天项目内容，其中，第一视频显示区201包括显示本地摄像头获取数据本地视图显示区和远程视图显示区，第二视图显示区202可呈现应用层项目内容(如，直播视频、网页视频、VOD展示、应用程序画面等)。
如图8b，在一些实施例中，用户可关闭本地视图显示区的视频内容，仅保留第远程视图显示区的远程视频数据和第三视图显示区的内容。在该情况下，检测到用户关闭本地视图显示区，摄像头自动关闭。在可选方式中，马达下降至初始位置。
可选的，对于图8a、8b，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，本地视图显示区2011和远程视图显示区2012优先级高于第二视图显示区202的优先级，当用户 在第二视图显示区202使用获取选择器和画面切换时，不遮挡第一视图显示区201的画面展示；以及，根据用户的选择使第三视图显示区的大小和位置发生变化时，第一视图显示区201和第二视图显示区202的大小和位置不受影响。
也可以呈现相同优先级级的显示画面，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。
作为一种示例，第一、二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，直播视频、网页视频、VOD展示、应用程序画面等)。
如图9-10所述，在一些实施例中，当用户打开视频聊天应用，在第一视图显示区呈现视频聊天界面，第二视图显示区可通过HDMI2.0接入外接设备而呈现直播内容；当接收到用户输入的切换到点播视频的指令时，第二视图显示区通过HDMI1.0连接的第二控制器而呈现点播内容。
如图9所述，在一些实施例中，当用户打开视频聊天应用，在第一视图显示区呈现视频聊天界面，第二视图显示区可通过HDMI2.0接入外接设备而呈现直播媒体播放内容；当接收到用户输入的切换到点播视频的指令时，第二视图显示区通过HDMI1.0连接的第二控制器而呈现点播媒体播放内容。
本申请提供一种显示设备，使之在呈现视频媒体播放内容的同时，呈现视频聊天内容。具体包括摄像头，该摄像头被配置为采集环境图像数据；
显示器，该显示器被配置为显示用户界面，其中，所述用户界面包括第一视图显示区和第二视图显示区，所述第一视图显示区用于呈现视频聊天内容，所述第二视图显示区用于呈现媒体播放内容，所述媒体播放内容包括直播媒体播放内容或点播媒体播放内容；
与所述显示器通信的第一控制器，被配置为执行呈现用户界面，以及通过直播媒体播放内容输入通道连接外接设备；
与所述第一控制器通信的第二控制器，被配置为解码所述摄像头采集的环境图像数据，并将所述解码后的环境图像数据传输至所述第一控制器进行呈现，以及被配置为解码所述点播媒体播放内容；所述第一控制器还被配置为：接收用户输入，确定所述用户输入事件的类型；检测到用户在在第二视图显示区输入的从所述直播媒体播放内容切换到所述点播媒体播放内容的指令，所述第一 控制器从与外接设备相连的第一内容输入通道切换至与所述显示装置内的第二控制器连接的第二内容输入通道。
如图11a和11b，摄像头安装在第二控制器上，且有些用到摄像头的应用存储于第二控制器，另一些用到摄像头的应用存储于第一控制器。因此，双芯片需要实现摄像头的共享。
在一些实施例中，第二控制器连接物理MIPI接口的摄像头。另一些实施例中，也可以是USB等接口的摄像头。在第二控制器设置/dev/video0的节点，该节点用于指示第二控制器上的摄像头输入接口。
当第二控制器上的摄像头相关应用软件要打开设摄像头时，其实打开的就是第二控制器的/dev/video0节点。设置采集确定分辨率的图像，譬如采集1080P的分辨率的图像，然后通过USB连接线或其他连接线，传输至第一控制器进行呈现。
而第一控制器的摄像头相关应用软件用到第二控制器的物理摄像头时，可以将第二控制器视为一个通过USB接口连接的摄像头，且将第二控制器视为从设备(usb camera device)，第一控制器视为主设备(usb camera host)。
A和N之间通过物理USB线相连，这样在第一控制器就会识别有到一个USB摄像头设备接入，在第一控制器就会生成/dev/video0节点，但是由于N能力有限，A端需要先进行H264编码或者使用其他编码方式，然后将编码后的数据传输给N，N端解码后显示图像。
当第一控制器摄像头相关应用软件使用摄像头的时候，其实打开的就是第一控制器/dev/video0节点。为使第一控制器/dev/video0节点能够接收A芯片发送的摄像头接收的数据，需要在A芯片端实现虚拟摄像头，即gadget camera。要实现一个gadget camera，需要在A芯片实现uvc-gadget(USB video class)应用程序作为驱动程序。
在uvc-gadget应用程序中首先需要在A芯片虚拟出/dev/videoX输出节点，然后需要对uvc事件初始化，即填充uvc_device的probe和comit，将UVC事件的setup、data、streamon、streamoff，通过VIDIOC_SUBSCRIBE_EVENT注册到驱动里，之后就是循环处理UVC事件，将从A的/dev/video0中拿到的数据输出到/dev/videoX中，然后通过USB总线将数据传输给N。
图12为摄像头共享控制的第一控制器调用摄像头数据采集的流程图。
A芯片上uvc-gadget应用通过例如V4L2接口，从A芯片节点video0读取MIPI摄像头的数据，之后通过USB总线传输给第一控制器。
其中，(V4L2是Video4linux2(Video for Linux two)的简称，为Linux中关于视频设备的内核驱动，V4L2是Linux操作系统下用于采集图片、视频和音频数据的API接口，主要用于采集USB摄像头。
对于第一控制器来说，A就相当于一个USB摄像头设备，通过读第一控制器的/dev/video0就可以正常读到A芯片MIPI摄像头皮的数据，如果第一控制器能力有限，可以根据第一控制器需求对视频数据提前进行裁剪，传送第一控制器上能够处理的摄像头数据。
一般情况下，V4L2采集视频数据具体包括：首先，打开视频设备文件，进行视频采集的参数初始化，通过V4L2接口设置视频图像的采集窗口、采集的点阵大小和格式；其次，申请若干视频采集的帧缓冲区，并将这些帧缓冲区从内核空间映射到用户空间，便于应用程序读取/处理视频数据；第三，将申请到的帧缓冲区在视频采集输入队列排队，并启动视频采集；第四，驱动开始视频数据的采集，应用程序从视频采集输出队列取出帧缓冲区，处理完后，将帧缓冲区重新放入视频采集输入队列，循环往复采集连续的视频数据；第五，停止视频采集。
双硬件系统芯片共用一个摄像头，为避免在第一控制器使用摄像头时，A芯片再调用摄像头，本申请公开了一种调用摄像头的分配方法。
图13为摄像头共享控制的第一控制器调用摄像头时逻辑流程图。
在一种实施例中，当前没有应用占用摄像头时候，在第一控制器端打开摄像头应用，通过双系统通信方式在A芯片上写标记位(把当前N上使用的摄像头节点记入属性值sys.camera.nova_used保存)，标记当前N正在使用摄像头节点Video0。如sys.camera.nova_used＝0。当第一控制器不使用摄像头时，在A重置标记位，标记当前N没有使用任何摄像头节点，sys.camera.nova_used＝-1；
同样的，在A芯片上打开摄像头应用时，会在A芯片上写标记位(把当前N上使用的摄像头节点记入属性值sys.camera.aml_used保存)，标记当前A正在使用摄像头节点Video0，如sys.camera.aml_used＝0；关闭释放摄像头时候，重 置标记位，标记当前A没有使用任何摄像头节点，sys.camera.aml_used＝-1。
图14为摄像头共享控制的第二控制器调用摄像头时逻辑流程图；
如果第一控制器上已经有应用打开并使用摄像头，第二控制器上应用再打开使用摄像头时候，A芯片上应用调用摄像头的框架层接口时候时候，摄像头的框架层会先取出摄像头的属性sys.camera.nova_used中的值，得到已经占用的摄像头节点usedCameraId，提示目前摄像头被占用。
当A芯片上通过外接的USB接口，连接有外置摄像头。A芯片上应用再打开使用摄像头时候，A芯片上应用调用摄像头的框架层接口时候时候，摄像头的框架层会先取出摄像头的属性sys.camera.nova_used中的值，得到已经占用的摄像头节点usedCameraId，A中应用申请打开的camera节点的ID比较，如果相同，提示目前摄像头被占用；不同，允许打开应用指定的camera Id的摄像头。如果此时A应用调用摄像头时候没有指定camera ID，框架层会默认打开后置摄像头，此时需要遍历整个摄像头id的列表，如果当前used Camera Id是后置，会查找下一个后置摄像头，如果未找到，提示当前要打开的摄像头被占用；如果找到了新的后置摄像头，则打开新找到的这个后置摄像头。
本申请提供一种显示设备，使之在呈现视频播放内容的同时，呈现视频聊天内容。具体包括摄像头，该摄像头被配置为接收视频聊天内容；显示器，该显示器被配置为显示用户界面；与所述摄像头电连接的第二控制器，被配置为检测所述摄像头的状态，以及对所述摄像头获取的图像数据进行解码；与所述显示器通信的第一控制器，被配置为执行呈现用户界面：检测到用户启动存储于所述第一控制器上的摄像头相关应用程序，所述第二控制器上写入标记位，标记所述摄像头的运行状态。本申请通过安装在显示设备内的摄像头将获取的视频聊天内容，并使第一控制器和第二控制器的摄像头相关应用程序在使用摄像头时，不产生冲突。
基于本申请中示出的示例性实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。此外，虽然本申请中公开内容按照示范性一个或几个实例来介绍，但应理解，可以就这些公开内容的各个方面也可以单独构成一个完整技术方案。

此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖但不排他的包含，例如，包含了一系列组件的产品或设备不必限于清楚地列出的那些组件，而是可包括没有清楚地列出的或对于这些产品或设备固有的其它组件。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
