在一些实施例中，显示设备200和外部设备400可以具备ARC功能。ARC功能是HDMI端子规格中的功能，目前的多媒体设备，例如电视、功放等设备都支持ARC功能。
ARC功能可以提高音频质量，还可以使得显示设备和外部设备之间的信号传输简单化。例如，显示设备可以通过ARC功能将音频信号上行发送到其连接的条形音箱、单箱式家庭影院、AV接收机或其他可发声音频设备，通过在显示设备和音频设备之间形成“握手”来创建双向信息的通道，不再需要在显示设备和其连接的上述设备之间架设光纤音频电缆，从而减少家庭线缆布设。
在一些实施例中，显示设备200和外部设备400还可以启用HDMI-CEC(High Definition Multimedia Interface-Consumer Electronics Control，高清多媒体接口消费类电子产品控制)控制服务，以实现通过单一的遥控器，或单一的控制装置控制所有通过HDMI端子连接的设备。例如，如图2所示，为显示设备上HDMI-CEC控制服务配置界面的示意图，用户通过操作控制装置以点击图2所示例的配置界面上的按钮400，可以使显示设备被配置为启动或关闭HDMI-CEC控制服务。
在一些实施例中，通过CEC信号可以使得显示设备控制HDMI端子上所连接的设备， 实现如单键播放(One Touch Play)，设备待机(System Standby)、设备唤醒等控制功能。
例如，用户通过按压控制装置上的待机按键控制显示设备待机，显示设备可通过HDMI-CEC控制服务向通过HDMI端子连接的外部设备发送HDMI-CEC信号，以使外部设备也进入待机状态。又例如，用户可以按压外部设备上的按钮控制外部设备开机，外部设备可通过HDMI-CEC控制服务向显示设备发送HDMI-CEC信号，以使显示设备自动开机，并自动切换至HDMI信号源，以播放外部设备提供的多媒体内容。
图3示例性示出了外部设备的唤醒流程。
如图3所示，基于用户输入，例如按压控制装置上的电源键，使得显示设备由待机状态进入开机状态，或者，例如按压显示设备上的电源键，使得显示设备由关机状态进入开机状态。
一些实施例中，以STR(Suspend To RAM，挂起到内存，又称内存待机模式)待机状态为例，对显示设备从开机状态进入STR待机状态的流程和显示设备从STR待机状态进入开机状态的流程进行说明：
示例性的，用户可通过按压控制装置上的电源键向处于开机状态的显示设备输入待机指令，显示设备接收到该待机指令后，将硬件运行状态信息存储到内存(例如RAM)中，释放正在使用的硬件资源(例如显示器、硬盘、外部设备等)并冻结进程；PM模块控制电源电路将除RAM和MCU以外的其他硬件进行掉电，也即控制电源电路仅需保持对RAM和MCU的供电；以及发送关屏广播以使显示器关屏。至此，显示设备进入STR待机状态。显示设备处于STR待机状态时可以降低整机功耗。
进一步，示例性的，用户可通过按压控制装置上的电源键向处于STR待机状态的显示设备输入待机至开机的电源启动指令，当显示设备接收到该电源启动指令时，从内存中读取硬件运行状态信息，基于读取到的硬件运行状态信息进行硬件初始化；PM模块控制电源电路为各硬件供电，并启动操作系统程序恢复至挂起前的状态；以及发送亮屏广播使得显示器亮屏。至此，显示设备进入开机状态。通过上述处理，可以节省显示设备从待机状态进入开机状态的等待时间，提高开机速度。
在显示设备被开机后，显示设备的控制器(例如图1C所示的控制器)中，设备查找模块通过轮询线程(Polling Thread)的方式，在显示设备的总线上持续地检测显示设备的HDMI端子是否有新接入的外部设备。
当检测到外部设备通过HDMI连接线插入显示设备的HDMI端子后，显示设备的控制器中，逻辑地址分配模块根据CEC协议为外部设备分配相应的逻辑地址。
示例性的，逻辑地址分配模块为外部设备分配相应的逻辑地址的过程包括：
逻辑地址分配模块获取外部设备出厂时被设置的逻辑地址，例如“5”，之后检查该逻辑地址的合法性，例如检查该逻辑地址是否已分配给显示设备连接的其他外部设备，如果否，则确定该逻辑地址合法，从而将该逻辑地址分配给该外部设备；如果是，则确定该逻辑地址不合法，此时逻辑地址分配模块可再次获取外部设备出厂时被设置的另一逻辑地址，例如“15”，重复以上过程，直至完成为该外部设备分配相应的逻辑地址。
然后，显示设备控制器中的设备信息上报模块采集外部设备的设备相关信息，如设备物理地址、设备名称、设备所属厂家、设备的电源状态等，并将这些设备相关信息上报给设备唤醒模块。
其中，在显示设备获取到外部设备的物理地址之前，显示设备可以与外部设备之间建立广播式的通信，而当显示设备获取到外部设备的物理地址之后，则可以通过外部设备的物理地址建立显示设备与外部设备之间点对点的通信。
所述设备名称(OSD name)用于区别接入显示设备的多个外部设备，并且可以用于在显示设备的UI界面对其连接状态进行显示。
所述设备所属厂家，即制造商ID(vendor ID)用于区别接入显示设备的多个外部设备的制造厂商，即外部设备的品牌。在一些实施例中，还可以根据所述制造商ID对外部设备进行快速初始化。
在一些实现方式中，设备相关信息可以包括上述信息的一种或数种的组合，也可以包括在本申请中并未提及的其他设备相关信息。
此外，显示设备中的每个HDMI端子配置有固定的物理地址，外部设备接入不同的HDMI端子则对应不同的端子编号和物理地址，例如HDMI1、HDMI2、HDMI3、HDMI4等，通过HDMI端子的物理地址可以确定外部设备连接哪个HDMI端子。在一些实施例中，设备信息上报模块还可以采集外部设备连接的HDMI端子的物理地址并上报给设备唤醒模块。
设备唤醒模块则可以根据所述设备相关信息和HDMI端子的物理地址，发送设备唤醒指令(例如通过CEC协议发送的指令)至外部设备以唤醒外部设备。
在一些实施例中，设备唤醒模块还可用于判断外部设备是否具备ARC功能。具体的，设备唤醒模块向外部设备发送用于确定外部设备是否具备ARC功能的消息，根据外部设备的应答消息确定该外部设备是否具有ARC功能。例如，设备唤醒模块发送消息req init arc至外部设备，若外部设备收到该消息后无应答，则设备唤醒模块可以确定外部设备不具备ARC功能；若外部设备收到该消息后应答initiate arc消息，则设备唤醒模块确定外部设备具备ARC功能，进一步，显示设备控制器中的音频数据流使能模块才进行其工作。
所述音频数据流使能模块，用于对已唤醒的外部接入设备进行使能，并通过固定ARC通道发送已经处理的音频数据流至外部设备。
这里，ARC通道即为显示设备中控制器、HDMI端子、HDMI连接线以及外部设备组成的一个音频数据流传送通道。显示设备输出的音频数据流经由该ARC通道至外部设备。这里，音频数据流为适用于ARC功能的音频信号，例如，适用于ARC功能的音频信号的信号波形与常规音频信号的信号波形不同。
需要说明的是，当前，所述设备信息上报模块是基于安卓系统原生的代码框架实现采集外部设备的设备相关信息并上报给设备唤醒模块的，而安卓系统原生的代码框架中采取的是设备集中发现、集中处理、集中上报的策略。图4则示例性示出了在这一策略下设备信息上报模块的处理流程，图5则示例性示出了图4中各阶段的处理流程。
如图4和图5所示，逻辑地址分配模块为连接的每一外部设备分配相应的逻辑地址之后，顺次执行以下五个阶段：设备物理地址获取阶段、设备名称获取阶段、制造商ID获取阶段、电源状态获取阶段、信息打包上报阶段。
在上述前四个阶段的任一阶段中，设备信息上报模块依次向显示设备连接的每一外部设备发送用于指示获取相应信息的获取请求。设备信息上报模块每收到一个外部设备的响应消息，则将mProcessCount做加1操作，直至mProcessCount等于DeviceCount(用于表示显示设备连接的外部设备的数量)时，才会进入下一阶段，也即设备信息上报模块接收到所有外部设备的响应消息之后，才会进入下一阶段。
同时，在上述前四个阶段的任一阶段中，如果显示设备连接的任一台外部设备不响应上述获取请求，那么设备信息上报模块将开启超时重发机制，在超时重发机制下，设备信息上报模块可在超时时间(例如2秒)内未接收到外部设备的响应消息时，再次向该外部设备发送获取请求，直至接收到该外部设备的响应消息，或者获取请求的发送次数达到预设的重发次数，例如5次。最后，当所有外部设备的电源状态均获取成功后，才进入信息打包上报阶段。
基于上述描述，在图1A所示例的应用场景中，假设Direct TV机顶盒500不响应上述前四个阶段任一阶段的获取请求，例如Direct TV机顶盒500不应答设备物理地址和制造商ID的消息，那么，将在图4所示例的前四个阶段中均开启超时重发机制，例如，重发5次获取请求、每次间隔时间2s，那么设备物理地址获取阶段需要耗时5*2s，制造商ID获取阶段需要耗时5*2s。进一步地，如果DVD600也不响应上述前四个阶段任一阶段的获取请求，由此将导致需要较长时间，例如44秒才能唤醒音频设备。
为了解决上述问题，本申请提供一种音频设备的唤醒方法。
图6示出了音频设备的唤醒的方法的流程图，包括以下步骤：
步骤S61：在显示设备被配置为控制电源管理模块使得显示设备处于待机状态的情况下，响应于用户输入的待机至开机的电源启动指令，控制电源管理模块使得显示设备从待机进入开机状态。
步骤S62：在确定显示设备连接的多个外部设备中存在音频设备时，先控制音频设备进入开机状态，再控制除音频设备之外的其他外部设备进入开机状态。
在一些实施例中，可以通过为外部设备分配的逻辑地址，确定外部设备的设备类型是否为音频设备。例如，逻辑地址为5，表示设备类型为音频设备，逻辑地址为4，或8，或11，表示设备类型为DVD设备。
在一些实施例中，在通过为外部设备分配的逻辑地址，确定外部设备的设备类型为音频设备之后，可以将该逻辑地址存储至预设的第一列表，类似的，在通过为外部设备分配的逻辑地址，确定外部设备的设备类型不为音频设备之后，可以将该逻辑地址存储至预设的第二列表。
基于此，设备信息上报模块在采集外部设备的设备相关信息时，可以首先检查是否存在第一列表，如果存在，则设备信息上报模块首先根据第一列表中的逻辑地址采集音频设备的设备相关信息，例如按顺序依次执行上述设备物理地址获取阶段、设备名称获取阶段、制造商ID获取阶段、电源状态获取阶段、信息打包上报阶段，并向音频设备发送设备唤醒指令以使其进入开机状态；在音频设备的设备相关信息均上报完毕之后，再根据第二列表中的逻辑地址采集其他外部设备的设备相关信息，并向该其他外部设备发送设备唤醒指令以使其进入开机状态。
由此可见，通过本申请提供的方法，可以缩短显示设备开机后，音频设备的唤醒耗时，提高音频设备的唤醒效率，提升用户体验。
在一些实施例中，为了进一步提高显示设备开机后，音频设备的唤醒效率，本申请还提出以下改进：
由于设备相关信息中：设备名称用于区别接入显示设备的多个外部设备，并且可以用于在显示设备的UI界面对其连接状态进行显示。制造商ID用于区别接入显示设备的多个外部设备的制造厂商，即外部设备的品牌。在设备唤醒之前，并不需要立即使用这些信息。
因此，示例性的，可以将图4中所示例的设备信息上报模块的处理流程中的设备名称获取阶段、制造商ID获取阶段，均调整至音频设备唤醒之后再执行。这样，可以缩短设备相关信息获取的时间，从而进一步缩短设备唤醒时间。
由此可见，通过上述改进可以进一步缩短显示设备开机后，音频设备的唤醒耗时，提高音频设备的唤醒效率，提升用户体验。
尽管已描述了本申请的优选实施例，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申请范围的所有变更和修改。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包括这些改动和变型在内。
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。
