在实际应用中，基于上述控制装置与显示设备的配置框图，用户可以通过移动设备100B向显示设备200推送媒体文件，以通过显示设备进行媒体文件播放。
需要说明的是，在本申请提供的一种向显示设备推送媒体文件的方法中，向显示设备推送媒体文件的终端可以是个人电脑(Personal Computer，PC)等非移动设备，也可以是如上所述的移动设备100B，本申请并不限定终端类型。
以上述移动设备100B和显示设备200为例，在一些实施例中，移动设备100B和显示设备200中分别安装有与媒体播放相关的应用程序(以下一些实施例中为描述方便，将该应用称为媒体播放应用)，用户通过移动设备100B中的应用程序可与显示设备200进行交互通信，以在显示设备上进行媒体播放相关操作。
在一种应用场景中，用户可通过移动设备中安装的与显示设备相关的媒 体播放客户端应用程序直播或点播视频节目进行播放。在一些实施方式中，用户通过移动设备中的客户端应用程序向显示设备发送媒体播放指令，其中携带视频文件的URL(Uniform Resource Locator，统一资源定位符)，显示设备中的服务端应用程序根据该指令中的视频文件URL获取网络服务器内存储的视频并进行播放。这里，视频文件的URL可以是提供视频文件的各种服务器地址。
在另一种应用场景中，用户可将移动设备中存储的本地媒体文件(例如视频文件、图片文件、音频文件)推送至显示设备进行播放。在一些实施方式中，用户通过移动设备中的客户端应用程序向显示设备发送媒体播放指令，其中携带媒体文件的URL以及通过数字编码技术而对移动设备本地的媒体文件进行编码后的媒体文件，显示设备根据该媒体文件的URL对接收到的媒体文件进行解码并播放。这里，媒体文件的URL可以是媒体文件在移动设备本地的存储位置或路径。
需要说明的是，移动设备与显示设备间的交互过程只能在显示设备处于运行模式下完成。若显示设备处于待机模式，则需要用户通过遥控器上的电源键唤醒待机模式下的显示设备，使得显示设备由待机模式进入运行模式，从而显示设备中与移动设备交互的服务被开启后才能与移动设备进行交互通信。此种情况下，显示设备恢复到运行模式需要较长的开机时延，用户体验较差。
为了解决上述问题，本公开实施例提供一种用于显示设备的媒体文件处理方法，针对显示设备引入了“自定义”模式，该模式下显示设备中与移动设备交互的服务被开启。首先在接收到移动设备发送的唤醒信号后，将显示设备从待机模式唤醒为自定义模式，这样当移动设备向处于自定义模式的显示设备发送媒体播放指令后，由于显示设备此时已被唤醒，因此可以快速响应该指令以进行媒体文件播放。
本公开实施例提供的用于显示设备的媒体文件处理方法包括：

在处于所述自定义模式期间，接收到与所述显示设备关联的移动设备发送的媒体文件推送指令，点亮所述显示设备的屏幕，以及根据所述媒体文件推送指令进行媒体文件播放，使得显示设备进入正常的运行模式。
在一些实施方式中，所述根据所述媒体文件推送指令进行媒体文件播放是通过下述执行：

图2为根据上述实施例提供的一种显示设备的模式切换示意图。
如图2所示，本公开实施例中，显示设备具有3种模式：待机模式、自定义模式和运行模式，这3种模式可在一定条件下进行切换。
待机模式下，显示设备中的WiFi模块保持上电状态即处于开启状态，能够接收基于WiFi协议发送的唤醒信号，并能够被唤醒信号唤醒而触发开机，以进入自定义模式。待机模式下的显示设备中媒体输出功能的相关部件处于 关闭状态，比如显示设备的屏幕为不亮状态，显示设备的音频输出为静音状态。
待机模式下的显示设备中的大部分系统服务或全部系统服务处于关闭状态。
在一些实施方式中，网络服务被开启，所述网络服务用于使得显示设备与移动设备建立关联；这样在显示设备进入自定义模式后，无需进行网络服务回连，避免网络服务回连的时延，以加快后续显示设备对移动设备推送媒体文件进行播放的速度。
在一些实施方式中，媒体文件播放服务被开启，这样在显示设备进入自定义模式后，避免媒体文件播放服务恢复的时延，能够使得移动设备快速发现网络内的显示设备。
这里，媒体文件播放服务包括在线媒体文件播放服务和本地媒体文件播放服务。在线媒体文件播放服务，如微信电视应用相关服务，用于使得显示设备在接收到与显示设备关联的移动设备发送的媒体文件推送指令之后，根据媒体文件推送指令中包含的媒体文件源地址，从与媒体文件源地址对应的网络服务器获取在线媒体文件，并对在线媒体文件进行播放。本地媒体文件播放服务，如媒体中心应用相关服务，用于使得显示设备接收到与显示设备关联的移动设备发送的媒体文件推送指令之后，根据媒体文件推送指令中包含的移动设备本地媒体文件地址，从移动设备获取本地媒体文件，并对本地媒体文件播放。
自定义模式下，显示设备中的部分系统服务被开启。被开启的系统服务至少包括监听服务，该监听服务用于使得显示设备监听与显示设备关联的移动设备发送的媒体文件播放指令。
在一些实施方式中，处于自定义模式的显示设备的屏幕为不亮状态，音频输出为静音状态。这样，能够为用户营造一种显示设备在自定义模式下和待机模式下的表现一致的体验。
运行模式下，显示设备可正常工作，比如能够与移动设备交互，响应移 动设备发送的媒体文件播放指令。运行模式下的显示设备，其音频输出为开启状态，屏幕为点亮状态。
显示设备的上述三种模式可以在以下情况下进行切换：
对于处于运行模式的显示设备，当用户操作遥控器上的电源键，或者操作电视背板上的电源键，或者通过语音控制进行关机时，处于运行模式的显示设备进入待机模式。
对于处于待机模式的显示设备，当用户操作遥控器上的电源键，或者操作电视背板上的电源键，或通过语音控制进行开机时，处于待机模式的显示设备进入运行模式。
对于处于待机模式的显示设备，当接收到唤醒信号后，从待机模式进入自定义模式。其中，用户启动移动设备上安装的与显示设备相关的客户端应用程序或者移动设备与显示设备加入同一网络中时，移动设备广播唤醒信号，使得处于待机模式的显示设备能够接收该唤醒信号并被该唤醒信号所唤醒以进入自定义模式。
对于处于自定义模式的显示设备，当用户通过操作移动设备上安装的与显示设备相关的客户端应用程序向显示设备发送媒体文件播放指令时，或者操作遥控器上的电源键，或者操作电视背板上的电源键，或语音控制时，处于自定义模式的显示设备进入运行模式。
对于处于自定义模式的显示设备，当在设定时长(比如60秒)内用户没有进一步操作，如没有接收到移动设备发送的媒体文件播放指令，则处于自定义模式的显示设备进入待机模式，以减少功耗。
从待机模式到自定义模式的过程中，显示设备进行休眠至内存(Suspend to RAM，STR)快速开机，在此过程中，部分服务被开启。其中，所述部分服务至少包括监听服务，所述监听服务用于使得显示设备监听与显示设备关联的移动设备发送的媒体文件播放指令。
在一些实施方式中，所述部分服务至少还包括：在线媒体文件播放服务和本地媒体文件播放服务。其中，在线媒体文件播放服务，用于使得显示设 备在监听到与所述显示设备关联的移动设备发送的媒体文件播放指令之后，根据所述媒体文件播放指令进行在线媒体文件播放；本地媒体文件播放服务，用于使得显示设备监听到与显示设备关联的移动设备发送的媒体文件播放指令之后，根据所述媒体文件播放指令通过与所述移动设备交互获取所述移动设备的本地媒体文件，并对所述本地媒体文件解码、播放。
在一些实施方式中，从待机模式到自定义模式的过程中，显示设备保持音频输出为静音状态，屏幕由未上电状态切换至上电状态但关闭屏幕背光。从自定义模式到运行模式的过程中，显示设备可取消音频静音，并打开屏幕背光以点亮屏幕，从而展示播放的媒体文件。
需要说明的是，屏幕处于不亮状态可以通过两种方式实现：屏幕断电、屏幕上电但关闭屏幕背光。在屏幕断电情况下，若需要使得屏幕切换至点亮状态，则需要先为屏幕上电，再开启屏幕背光，导致屏幕点亮时间较长、界面显示时间较长。在屏幕上电但关闭屏幕背光情况下，若需要使得屏幕切换至点亮状态，则仅需要开启屏幕背光，使得屏幕点亮时间较短、界面显示时间较短。这里自定义模式下屏幕为不亮状态，具体通过屏幕上电但关闭屏幕背光实现，是由于该方式下后续显示设备从自定义模式到运行模式时，可以直接通过打开屏幕背光，以快速实现屏幕点亮，提高用户满意度。
在一些实施方式中，从待机模式到自定义模式的过程中，显示设备还可以关闭开机动画服务，一方面可以降低显示设备的唤醒时延，另一方面显示设备接收到移动设备发送的媒体文件播放指令后，可以直接播放媒体文件，无需用户等待开机动画播放完才显示媒体文件播放界面。
处于自定义模式的显示设备监听到与所述显示设备关联的移动设备发送的媒体文件播放指令后，进入运行模式，并进行媒体播放。其中，若该媒体文件播放指令用于指示播放网络侧存储的媒体文件，则显示设备根据该媒体文件播放指令中携带的媒体文件URL获取网络侧的媒体文件并进行播放；若该媒体文件播放指令用于指示播放移动设备发送来的媒体文件，则显示设备接收移动设备发送来的该移动设备本地存储的媒体文件，并对接收到的媒体 文件进行解码后播放。
在一些实施方式中，显示设备在接收到媒体文件播放指令后，可首先切换到请求播放的媒体文件所对应的信号源，并播放所述媒体文件；然后再点亮屏幕，并禁止切换到待机前的信号源。由于在点亮屏幕时，通常会触发信号源的切换，使信号源切换到待机前的信号源，而本公开实施例中，在点亮屏幕时，禁止将信号源切换到待机前的信号源，从而可以避免请求播放的媒体文件所对应的信号源不被切换，进而保证该媒体文件的播放。另外，由于在点亮屏幕之前将信号源切换到请求播放的媒体文件所对应的信号源，以播放该媒体文件，这样当屏幕被点亮后，用户可以立即看到播放的媒体文件，提高了用户感受。
在一些实施方式中，显示设备接收到移动设备发送的媒体文件播放指令后，还可关闭监听服务。由于此时显示设备已经进入运行模式，与移动设备之间已经建立通信连接，因此可以通过该通信连接与移动设备之间进行通信，而无需通过监听方式接收移动设备发送的媒体文件播放指令。
在一些实施方式中，处于待机模式的显示设备，其网络服务可以为开启状态，这样，基于该网络服务，显示设备在接收到唤醒信号后向发送该唤醒信号的移动设备发送关联信号，该关联信号中可携带显示设备的相关信息。移动设备接收到该关联信号后，可以与该显示设备建立关联。其中，显示设备的相关信息可包括显示设备的名称、显示设备的媒体访问控制(Media Access Control，MAC)地址，包括有线MAC地址和WiFi MAC地址等。移动设备与显示设备关联后，将连接的网络名称(服务集标识(Service Set Identifier，SSID))、显示设备的MAC地址、电视名称等信息保存为一条记录进行存储。
本公开的上述实施例中，一方面，首先通过终端广播的唤醒信号提前唤醒处于待机模式的显示设备，以使处于待机模式的显示设备进入自定义模式，其中，处于自定义模式的显示设备可被终端发现以进行显示设备和移动设备之间的关联；接着在用户对终端上的媒体文件进行推送操作时，处于自定义 模式的显示设备能够接收到推送操作指令，自动触发处于自定义模式的显示设备进入运行模式并进行媒体文件播放，从而实现了待机模式下的显示设备对推送的媒体文件进行播放。另一方面，控制自定义模式的显示设备的屏幕为不亮状态，而运行模式的显示设备的屏幕为点亮状态，为用户提供一种向处于待机模式下的显示设备推送媒体文件的视觉体验。
进一步的，由于无需像现有技术中一样“先通过电源键唤醒待机模式下的显示设备，再向显示设备推送媒体文件进行播放”，上述示例中通过终端广播的唤醒信号提前唤醒待机模式的显示设备以进入自定义模式，处于自定义模式的显示设备能够接收到终端上媒体文件的推送操作，不仅能够给用户提供一种待机模式下无感推送媒体文件播放的视觉体验，而且能够减少从待机模式到进行媒体文件播放的时延。
本公开实施例可基于显示设备的操作系统实现。

系统内核301还用于接收与显示设备关联的移动设备发送的媒体文件播放指令，并将该媒体文件播放指令发送给框架层302。
框架层302还用于监听媒体文件播放指令，以使处于自定义模式的显示设备进入运行模式，并触发应用层303中的应用程序根据所述媒体文件播放指令进行媒体播放。

如图4所示，该开关控制流程用于控制显示设备中的WiFi唤醒方式为开启状态或关闭状态，当用户长时间不采用显示设备中的WiFi唤醒方式时，可通过图4所示的流程将WiFi唤醒方式关闭进而可减少WiFi唤醒方式在待机模式中的消耗。如图所示，该流程包括：
S401～S404：Settings通过Flow API以及Middleware，确定显示设备的驱动环境是否支持WiFi唤醒方式。
在S404中，驱动环境读取底层驱动的参数信息确定显示设备可支持WiFi 唤醒方式，并向Settings返回是否支持WiFi唤醒方式的指示信息(如图中的WiFi唤醒模式状态参数)。
S405～S408：Settings确定驱动环境支持WiFi唤醒方式后，通过Flow API以及Middleware，一方面将用于描述WiFi唤醒方式的状态的指示信息写入驱动环境参数中，另一方面将用于描述WiFi唤醒方式的状态的指示信息写入系统属性参数中。
其中，WiFi唤醒方式的状态指显示设备的WiFi唤醒方式为开启状态或关闭状态；在一些实施方式中，用户可根据需求关闭或开启显示设备中的WiFi唤醒方式，进而触发Settings将用于描述WiFi唤醒方式的状态的指示信息一方面写入驱动环境参数中为MI模块提供判断，另一方面写入系统属性参数中为Middleware提供判断。
基于图4所示的流程，在一种应用场景中，当用户使用遥控器打开WiFi唤醒方式设置界面时，显示设备通过S401～S404获取当前的WiFi唤醒模式状态参数(该参数用于表明是否支持WiFi唤醒方式)，并将该参数显示在该界面中，比如当前的WiFi唤醒模式状态参数表明支持WiFi唤醒方式。该界面中还可呈现用于关闭/开启该模式的切换按键。当用户使用遥控器选择关闭WiFi唤醒模式时，显示设备通过S405～S408，更新该WiFi唤醒模式状态参数的取值，并将更新后的参数进行保存。
图5为本公开实施例中显示设备由运行模式进入待机模式的流程图。
如图5所示，当用户操作遥控上的电源键，或者操作电视背板上的电源键，或者语音控制关机时，处于运行模式的显示设备进入待机模式。如图所示，该流程包括：
S501：kernel进程接收待机指令。
其中，该待机指令可以是用户通过操作遥控上的电源键发送的，也可以是通过操作电视背板上的电源键发送的，还可以是通过语音控制关机发送的。
S502：kernel进程接收到待机指令后，生成待机事件，并向framework发送该待机事件。
S503～S505：framework接收到待机事件后，查找系统属性(system property)，根据查找到的系统属性(如WiFi唤醒模式状态参数，用于表明是否支持WiFi唤醒方式)确定显示设备是否开启WiFi唤醒方式，若开启则调用STRService(用于STR快速待机开机相关功能逻辑处理)，启动支持WiFi唤醒方式的待机流程。
该步骤中，可通过调用STRService的API启动待机流程(S506～S514)。
S506～S508：STRService通过Init进程向WiFi模块发送设置命令，该设置命令用于使得WiFi模块支持WiFi唤醒方式。
由于WiFi模块支持命令控制，而给WiFi模块设置命令需要根(root)属性，故在S506中STRService使用系统属性中的属性机制(比如ctrl.start)调用具有root权限的初始化(init)进程，将命令设置给WiFi模块，实现WiFi模块支持WiFi唤醒方式，支持WiFi唤醒方式的WiFi模块能够监听唤醒信号，该唤醒信号具体为指定端口数据报协议广播(User Datagram Protocol，UDP)组播包，例如Magic Packet包、mDNS(Multicast Domain Name System，组播域名系统)包。
在一些实施方式中，设置命令用于告知WiFi模块在WiFi唤醒方式中唤醒信号的格式以及接收唤醒信号的端口号，比如唤醒信号的发送方式为通过用户数据报协议广播，接收唤醒信号的端口号为9691。当处于待机模式的显示设备中的WiFi模块通过9691端口接收到使用UDP的唤醒信号(即9691端口UDP组播包)时，则确定唤醒方式为WiFi唤醒方式并执行基于WiFi唤醒方式的流程(即从待机模式切换到自定义模式)。
S509：STRService指示Network保持开启状态，用于保持处于待机模式下的显示设备中的网络服务不关闭。
S510：STRService指示framework杀死白名单之外的应用进程。
在一些实施方式中，白名单中包括与移动设备进行交互以及媒体播放相关的服务，比如包括在线媒体播放服务和本地媒体播放服务，用以获取媒体资源进行媒体播放。
在一些实施方式中，为了解决系统长时间待机，断电后系统重启产生运行变慢的问题，在S510中可关闭与通过WiFi唤醒的方式无关的后台应用及服务，对显示设备的系统进行优化。
S511～S514：STRService向WiFi模块发送开启指令，该开启指令用于保持WiFi模块不掉电，进而使得处于待机模式下的显示设备中的WiFi模块可接收移动设备广播的唤醒信号。
在实际应用中，STRService向Middleware通知进入待机状态，Middleware根据配置的系统环境(Environment)参数确定显示设备开启WiFi唤醒方式，因此向WiFi模块发送开启指令以使WiFi模块保持开启状态。
进一步地，Middleware根据系统环境参数确定需要关闭蓝牙功能、音频输出等功能，因此关闭蓝牙功能、音效输出等外部设备。
在一些实施方式中，在S512～S513中，若Middleware根据配置的系统环境参数确定显示设备已关闭WiFi唤醒方式，则关闭WiFi模块。
由于在待机模式下，显示设备中的网络服务(Network)是开启的，因此显示设备在接收到唤醒信号后可以向发送该唤醒信号的移动设备发送关联信号。关联信号中携带有显示设备的IP地址、MAC地址、显示设备的名称等信息。移动设备接收到该关联信号后，可与该显示设备建立关联。
以移动设备为智能手机、显示设备为智能电视为例，当用户启动智能手机上安装的与智能电视相关的客户端应用程序或智能手机与智能电视加入同一无线局域网中时，智能手机在无线局域网内广播唤醒信号，处于待机模式的智能电视接收到该唤醒信号后向智能手机发送关联信号，智能手机接收该关联信号后，可以直接与之建立关联；或者，弹出如图6所示的界面，用户可根据需求选择“客厅电视”，与之建立关联。如果该无线局域网内还有其他智能电视，则这多个智能电视在接收到智能手机广播的唤醒信号后，会向智能手机发送关联信号，这样智能手机可以接收到多个智能电视发送的关联信号，这多个智能电视的信息被显示在智能手机的用户界面中，以供用户选择其中的一个或多个智能电视与之关联。
图7为本公开实施例中显示设备由待机模式进入自定义模式的流程图。
如图7所示，当用户启动移动设备上安装的与显示设备相关的客户端应用程序或者移动设备与显示设备加入同一网络中时，处于待机模式的显示设备进入自定义模式。如图所示，该流程包括：
S701：WiFi模块接收移动设备广播的唤醒信号。
在实际应用中，以移动设备为智能手机为例，当用户启动智能手机安装的与显示设备相关的客户端应用程序(如聚好看应用程序)时，智能手机通过无线局域网广播唤醒信号，且当该客户端应用程序处于前台运行时，按照设定时长比如每10秒广播一次唤醒信号，该唤醒信号具体为9691端口UDP组播包。这样，在用户启动与显示设备相关的客户端应用程序时，表明用户有推送媒体文件至显示设备的意图，可周期性发送唤醒信号提前唤醒待机模式的显示设备，以便于其接收推送操作。或者，当智能手机与显示设备加入同一无线局域网中时，智能手机通过无线局域网广播唤醒信号，按照设定时长比如每20秒广播一次唤醒信号，该唤醒信号具体为9691端口UDP组播包。这样，也同样周期性发送唤醒信号提前唤醒待机模式的显示设备，以便于其接收推送操作。
由于处于待机模式的显示设备的WiFi模块不掉电，故可以接收到该唤醒信号，进而被唤醒进入自定义模式。
S702：WiFi模块接收到唤醒信号后，拉低与PM连接的通用输出/输入接口的电平，触发一次电平变化。
具体地，该唤醒信号使用用户数据报协议广播，携带有发送该唤醒信号的移动设备安装的客户端应用程序的指示信息。待机模式下，WiFi模块的通用串行总线(Universal Serial Bus，USB)控制器与主板的USB控制器相连，当WiFi模块接收到该唤醒信号时，识别为WiFi唤醒方式，则拉低与PM连接的通用输出/输入接口的电平，触发一次电平变化。
S703～S705：PM检测到电平变化后，通过SBOOT触发Kernel进程加载，启动开机流程。
S706～S707：Kernel进程向MI发送开机指令、向Framework发送唤醒(wakeup)键值。该开机指令用以指示MI确定唤醒方式是否为WiFi唤醒方式，若是则给屏幕上电但不点亮；该唤醒键值用以通知Framework进行开机流程。
MI模块接收到开机指令后，确定唤醒方式为WiFi唤醒方式，则给屏幕上电但不点亮屏幕，并通过设置系统属性sys.wifi.fake_standby.mode为true，记录显示设备进入自定义模式。
上述唤醒方式指触发显示设备由待机模式进入运行模式或自定义模式的方式，具体可包括遥控器键(电源键)唤醒方式，电视背板按键唤醒方式，WiFi唤醒方式以及语音唤醒等方式。
S708～S709：Framework接收到唤醒键值后，通过Middleware和MI模块，确定唤醒方式为WiFi唤醒方式。
具体地，Framework在接收到开机指令后，通过Middleware和MI模块确定唤醒方式为WiFi唤醒方式，进而执行自定义流程。
S710～S715：Framework确定唤醒方式为WiFi唤醒方式后，开启监听服务，关闭开机动画播放服务(BootAnimation)，并指示Middleware不发送亮屏广播通知、开启音效静音，关闭显示设备指示灯。
具体地，Middleware在接收到指示后，不发送用于触发其它应用和服务的亮屏广播通知，调用mute接口保持整机处于静音状态，关闭显示设备指示灯，进而显示设备进入自定义模式。
其中，在待机时安卓系统可以将系统运行状态进行保存，唤醒之后能够将状态进行还原；监听服务用于监听与显示设备关联的移动设备发送的媒体文件播放指令。
在一些实施方式中，若在设定时长(比如60秒)未收到与显示设备关联的移动设备发送的媒体文件播放指令，则显示设备关闭监听服务、由自定义模式进入待机模式；由于移动设备每10秒广播一次唤醒信号，即监听服务每10秒监听到一次唤醒信号，故显示设备每接收到一次唤醒信号则延迟60秒再 待机；这样，只要移动设备配置的应用程序处于前台运行状态，显示设备将会一直处于自定义模式，用户可随时通过操作移动设备进行媒体播放。
图8为本公开实施例中显示设备由自定义模式进入运行模式的流程图。
如图8所示，当显示设备接收到移动设备发送的媒体文件播放指令时，处于自定义模式的显示设备进入运行模式。如图所示，该流程包括：
S801：MediaCenter通过无线局域网接收媒体文件播放指令。
S802～S803：MediaCenter接收到该媒体文件播放指令后，向WindowManager模块发送开机广播通知，向Tile Transation发送信号源切换通知。
MediaCenter接收到该媒体文件播放指令后，一方面，向WindowManager发送开机广播通知以使WindowManager执行开机流程；另一方面，根据媒体文件播放指令获取媒体资源，确定用户播放的媒体文件的媒体格式，并根据该媒体格式向Tile Transation发送信号源切换通知，以使Tile Transation将播放界面切换至该媒体格式对应的播放界面。
S804：Tile Transation接收到信号源切换通知后，切换至对应的播放界面。
以待机前为DTV显示播放，用户所要求播放的媒体文件需要ATV显示播放为例，显示设备待机时会切换到一个空的信号源上，当媒体中心服务向信号源切换服务发送信号源切换请求消息后，信号源切换服务根据指示信息直接由空的信号源切换至ATV显示播放，而不是切换至DTV显示播放。
S805～S806：WindowManager接收到开机广播通知后，关闭监听服务，并调用STRService。
S807～S813：STRService被调用后，点亮屏幕、发送亮屏广播通知、指示Tile Transation禁止信号源切换、关闭开机动画播放，并指示Middleware取消音效静音、开启显示设备指示灯、蓝牙等外部设备服务，以使显示设备进入运行模式。
其中，发送亮屏广播通知后会触发Tile Transation将播放界面切换至待机前的播放界面，由于在S804中Tile Transation已将播放界面切换至用户播放 的媒体文件对应的播放界面，故Tile Transation在接收到亮屏广播通知后，禁止恢复到待机前播放界面的切换。
本公开的上述实施例中，通过移动设备广播的唤醒信号提前唤醒处于待机模式的显示设备，以使处于待机模式的显示设备开启部分服务进入自定义模式，这样，当用户操作与显示设备关联的移动设备时可触发处于自定义模式进入运行模式并进行媒体播放，实现了通过移动设备唤醒处于待机模式下的显示设备，减少了从待机模式到进行媒体播放的时延，提高用户使用体验。
尽管已描述了本公开的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本公开范围的所有变更和修改。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
