以上实施例介绍了显示设备的硬件/软件架构以及功能实现等内容，显示设备通过蓝牙模块222与蓝牙设备配对连接。在一些应用场景中，显示设备可以通过扫描来与多个蓝牙设备配对连接，本申请所述的蓝牙设备包括支持A2DP(Advanced Audio Distribution Profile，蓝牙音频传输模型协议)的设备，设备类型包括蓝牙音响、蓝牙耳机等。
第一方面：
在显示设备的扫描区域内如果存在多个蓝牙设备，由于各蓝牙设备响应和连接耗时不同，因此配对连接一般具有时间上的先后顺序。如图6所示，用户点击“添加配件”控件，可以扫描预设区域范围内的蓝牙设备，图6的示例中显示设备仅扫描到两个蓝牙设备，分别为小钢炮蓝牙音响和G10蓝牙音响，并率先与小钢炮蓝牙音响配对连接成功，之后与G10蓝牙音响配对连接成功，体现在界面上是小钢炮蓝牙音响排序在G10蓝牙音响之前。由于G10蓝牙音响是最后连接的蓝牙设备，因此默认将G10蓝牙音响激活，当播放音频时，声音由G10蓝牙音响发出。
当用户将G10蓝牙音响移动到可配对范围以外，或者将G10蓝牙音响关闭或断电，或者人为解除G10蓝牙音响与显示设备之间的配对连接(即解配操作)等情况，都会导致G10蓝牙音响与显示设备连接断开，如图7所示，体现在界面上是G10蓝牙音响被移除，仅保留了当前仍处于连接状态的小钢炮蓝牙音响。之前处于激活状态的G10蓝牙音响断开，由于蓝牙底层协议栈无法自动选择蓝牙设备进行发声，所以小钢炮蓝牙音响虽然处于连接状态但未被激活，则体现在发声上并非由小钢炮蓝牙音响输出音频，而是切换为由显示设备自带的扬声器输出音频。
也就是说，在上述情况下蓝牙输出通道处于不可用状态，在图8示例的音频输出界面中，列举了音频输出通道包括电视扬声器(TV Speaker)、ARC(Audio Return Channel，音频回传通道)和蓝牙(Bluetooth)，由于蓝牙输出通道不可用，因此“蓝牙”选项会被置灰，即用户无法对“蓝牙”选项进行选择和操作，显示设备默认跳转到电视扬声器去输出音频，即切换到TV功放，此时“电视扬声器”选项会显示被勾选。如果用户想要重新使用蓝牙设备去播放音频，只能将此时处于连接状态的小钢炮 蓝牙音响解配，然后再重新扫描配对，并激活最后连接的蓝牙设备，尤其是当已配对连接的蓝牙设备较多时，解配操作会更加繁复，显然这种操作使得用户实际体验很差。
对此，图9示出了一种蓝牙设备播放控制方法，本方法由显示设备中的控制器250被配置执行，即控制器250为本方法的执行主体，所述方法包括如下程序步骤：
步骤S10，响应于当前已激活的蓝牙设备转变为断开状态，从设备连接列表中获取目标蓝牙设备；所述设备连接列表中记录有当前与显示设备处于连接状态的蓝牙设备的设备信息。
步骤S20，将所述目标蓝牙设备设置为激活状态，以使所述目标蓝牙设备输出音频信号。
显示设备会维护一个动态的设备连接列表，在每次扫描配对后，将配对连接成功的蓝牙设备的设备信息存入列表中，以及将连接断开的蓝牙设备的设备信息移除，从而保证列表中记录的是当前处于连接状态的蓝牙设备。其中，设备信息包括但不限于设备名称、设备类型、设备ID、设备型号、MAC地址等用于识别设备的相关信息。
当前已激活的蓝牙设备一般为与显示设备最后配对连接的蓝牙设备，比如图6中的G10蓝牙音响，其由连接状态转变为断开状态时，此时更新后的设备连接列表中的蓝牙设备虽然都处于连接状态但未被激活，本申请需要从设备连接列表中选取某个目标蓝牙设备，并将目标蓝牙设备设置成激活状态，激活成功后的目标蓝牙设备即可输出和播放电视的音频信号，从而使音频信号通过蓝牙输出通道发声。
显示设备与不同的蓝牙设备配对连接时，蓝牙连接的信号强度可能不同，信号强度一般与设备之间的距离、蓝牙设备性能等因素有关，期望优先选取信号最强的蓝牙设备去输出音频，从而自动为用户提供最佳的音频播放效果。
在一些实施例中，蓝牙模块222可记录设备连接列表中每个蓝牙设备连接的信号强度，控制器250按照蓝牙连接的信号强度，对设备连接列表中记录的蓝牙设备进行排序，如果是按照信号强度从小到大(递增)的顺序排序，则排序在最末位的蓝牙设备即为信号强度最大的目标蓝牙设备；如果是按照信号强度从大到小(递减)的顺序排序，则排序在首位的蓝牙设备即为信号强度最大的目标蓝牙设备。
该实施例中，通过framework层(框架层)在设备连接列表中自动定向激活信号最强的目标蓝牙设备，使其输出音频完成发声，这种方式无需用户手动解配当前已连接的蓝牙设备，并能实现用户无感知下自动切换和激活发声的蓝牙设备，从而提升用户体验。
前述实施例实现用户无感知下自动定向激活目标蓝牙设备，在其他实现方式中，也可支持用户根据个人意愿自主选取期望激活的蓝牙设备，这种方式涉及到用户与显示设备UI之间的交互，用户接口265可以接收用户输入的操作指令，并将操作指令转发给控制器250去响应。
在一些实施例中，控制器250响应于接收到第一操作，控制显示器275显示设备连接列表界面，设备连接列表界面是将显示设备动态维护的设备连接列表以界面形式展示给用户查看，用户通过电视菜单，根据指定的第一操作即可定位到设备连接列表界面。
图10提供了设备连接列表界面的示意性示例，该界面中会显示处于连接状态的蓝牙设备的设备信息，设备信息可包括设备名称、设备类型、MAC地址等信息，便于用 户获知和区分每个蓝牙设备。比如，图10中第二行的设备信息中，设备名称为小钢炮，设备类型为蓝牙音响，MAC地址为A1:4F:18:88:F5:82；第三行的设备信息中，设备名称为SANSUI，设备型号为i37，设备类型为蓝牙耳机，MAC地址为22:23:23:57:9A:54。本申请还为设备连接列表界面中的每个设备信息增设对应的激活(Active)控件，比如图10中每行对应于一个已连接的蓝牙设备，每行中前部显示设备信息，后部显示激活控件。
在一些实施例中，控制器250响应于接收到对激活控件的点击操作，获取所述激活控件对应的目标设备信息，将目标设备信息指示的蓝牙设备设置为目标蓝牙设备。用户可以根据个人意愿任意选取设备连接列表界面中的某个蓝牙设备，比如用户点击小钢炮蓝牙音响对应的激活控件，则目标设备信息记为小钢炮蓝牙音响，将小钢炮蓝牙音响指示的蓝牙设备作为待激活对象，即将小钢炮蓝牙音响设置为目标蓝牙设备。本实施例中，通过用户与显示设备UI的交互，在用户感知下自主激活目标蓝牙设备去发声，满足了用户随意切换蓝牙播放设备的喜好，提升用户体验的满意度。
本申请提供自动定向激活信号最强的蓝牙设备，以及用户感知下自主激活期望发声的蓝牙设备这两种方式，在其他实施例中不限于其他选取和激活目标蓝牙设备的实现方式，可以根据实际应用需求进行设置。比如，可以按照设备连接列表中每个蓝牙设备的历史发声频率排序，选取播放音频最频繁的蓝牙设备作为待激活的目标蓝牙设备；或者，用户可以为各个蓝牙设备预设优先级，则选取设备连接列表中当前优先级最高的蓝牙设备去激活并发声，这种方式也可使被激活的发声设备更符合用户期望；又或者，可以按照配对连接的时间先后顺序对设备连接列表进行排序，并选取列表中当前最新/最晚连接的蓝牙设备去激活发声，等等。
在一些实施例中，在将目标蓝牙设备设置为激活状态后，记录蓝牙输出通道为可用状态，响应于接收到第二操作，控制显示器显示音频输出界面；所述音频输出界面中显示当前可用的音频输出通道，并标记蓝牙输出通道为选中状态。
用户通过电视菜单，根据指定的第二操作即可定位到音频输出(Audio Output)界面，在现有方式中最后配对连接的蓝牙设备断开后，音频输出界面中的“蓝牙”选项被置灰，即蓝牙输出通道不可用，音频信号无法通过任何已连接的蓝牙设备输出，因此被切换到TV功放去发声。而本申请中，目标蓝牙设备被激活后，一旦记录下蓝牙输出通道为可用状态，如图11所示，则音频输出界面中的“蓝牙”选项就不会被置灰，此时“蓝牙”选项获取焦点并且显示为被勾选，表明当前仍使用蓝牙输出通道来播放音频信号。
在一些实施例中，响应于用户在音频输出界面上的切换通道操作，获取切换通道操作对应的目标音频输出通道，控制所述目标音频输出通道输出并播放音频信号。参照图11，电视扬声器、ARC和蓝牙此时都处于可用状态(都未被置灰)，用户可以根据个人意愿选择切换到其他通道来输出音频。比如当前处于“蓝牙”输出，用户输入切换通道操作后，识别出该操作为用户点击了“电视扬声器”选项，即目标音频输出通道为“电视扬声器”，则控制电视扬声器输出并播放音频信号，从而由外部蓝牙功放切换到TV功放。本实施例方案可以支持用户在蓝牙输出通道、电视扬声器和其他音频输出通道之间随意切换，使得发声设备更适应用户实际需求，从而提升了用户使用体验。
在上述各实施例中，都是以最后配对连接的蓝牙设备断开后，设备连接列表为非空列表为前提，从列表中择一目标蓝牙设备去激活和发声。在实际应用中，显示设备的扫描和可配对范围内可能仅有一个蓝牙设备，即设备连接列表中仅有1个记录，一旦该单独的蓝牙设备断开，该蓝牙设备的记录将被移除，导致设备连接列表变更为空列表，也就无法从空列表中选得目标蓝牙设备。对此，在一些实施例中，如果设备连接列表为空列表，则切换到显示设备内置的音频播放器(即电视扬声器)去输出和播放音频信号。也就是说，当不具备蓝牙输出通道时，默认配置为切换到TV功放，以确保音频信号能够有效发声。
在一些实施例中，图12提供一种显示设备端自动选取激活信号最强的目标蓝牙设备的实现流程，更细节的描述请参照下述(A1)～(A11)。

(A7)：当前蓝牙设备连接断开，则将当前蓝牙设备从设备连接列表中移除，并判断当前被移除的蓝牙设备是否为激活状态。如果当前被移除的蓝牙设备不是激活状态，其本身就无法输出音频信号，那么移除后对蓝牙音频输出没有影响，即可结束流程；反之，如果当前被移除的蓝牙设备是激活状态，则执行(A8)。
(A8)：判断设备连接列表是否为空列表。如果不是空列表，则执行(A9)；如果是空列表，则执行(A11)。
(A9)：获取设备连接列表中各蓝牙设备的信号强度并进行排序，获取top信号强度对应的目标蓝牙设备，然后继续执行(A10)。

(B7)：执行成功后，当前待激活设备设置成激活状态，然后判断当前激活的蓝牙设备与之前相比是否发生变化，即判断当前激活的蓝牙设备与前一个激活过的蓝牙设备是否为同一个。如果判断结果为否，则执行(B3)；反之，如果判断结果为是，则执行(B8)。
(B8)：发送包含当前激活设备的codec configuration(编解码器配置)的广播，用以通知其他应用程序被激活的蓝牙设备已经发生变更，然后判断前一个激活过的蓝牙设备是否为空。如果前一个激活过的蓝牙设备为空，则执行(B12)；反之，如果前一个激活过的蓝牙设备不为空，则执行(B9)。

需要说明的是，本申请附图示出的各个UI界面图仅仅是示例性的，具体以显示设 备实际应用时的界面展示为准。
第二方面：
在本申请一些实施例中，还提供一种显示设备，包括：
遥控器，被配置为基于用户的操作产生配对信号；
显示器，被配置为呈现显示有操作提示的用户界面；
蓝牙模块，被配置为接收遥控器产生的配对信号；
分别与遥控器、蓝牙模块和显示器连接的控制器，控制器被配置为：
通过蓝牙模块接收遥控器产生的配对信号；
响应于配对信号，查找蓝牙模块的配置位置，配置位置是指蓝牙模块相对于显示器的物理位置；
基于蓝牙模块的配置位置，生成配对操作提示，配对操作提示用于提示遥控器在与显示设备的预设距离范围内对准蓝牙模块的位置；
将配对操作提示显示在显示器的用户界面中。
在一些实施例中，显示设备通常配备有遥控器，用户可以使用遥控器控制显示设备实现相应功能，提供体验良好的交互方式。而语音已经成为显示设备使用场景中最常见的功能，用户若想通过遥控器使用显示设备的语音功能，需要将遥控器通过蓝牙与显示设备进行配对。在配对之前，遥控器通过红外方式与显示设备建立连接，控制显示设备；只有遥控器与显示设备进行蓝牙配对，用户才可以使用遥控器使用语音功能。
显示设备和遥控器内均设置有蓝牙模块，实现显示设备与遥控器的蓝牙配对连接。配对操作时，遥控器需要与显示设备保持一定的距离范围，在用户模式下通常为3-6米范围内，在商场模式下通常为10-30厘米范围内。由于不同显示设备的蓝牙模块的设置位置不同，且显示设备上有的会标示丝印，有的没有，这将导致遥控器在与显示设备进行蓝牙配对连接时，无法轻易对准显示设备中的蓝牙模块。特别是在商场模式下，遥控器与显示设备相距较远时，遥控器无法短时间内对准显示设备的蓝牙模块，导致无法高效地与显示设备配对成功。
为便于提高遥控器与显示设备的蓝牙配对连接的效率，本发明实施例提供的一种显示设备，执行显示设备与遥控器配对的操作提示展示方法，可采用动画的方式在显示设备中展示操作提示，操作提示可基于蓝牙模块在显示设备中的配置位置生成，以提示用户该如何快速实现遥控器与显示设备的蓝牙配对连接。
图14中示例性示出了根据一些实施例的显示设备的结构框图。参见图14，本发明实施例提供的一种显示设备，包括：遥控器100、显示器275、蓝牙模块222和控制器250。遥控器内配置有蓝牙模块，用于基于用户的操作产生配对信号；显示器被配置为呈现显示有操作提示的用户界面；蓝牙模块222被配置为接收遥控器100产生的配对信号；控制器分别与遥控器100、蓝牙模块222和显示器275连接，显示设备内配置的蓝牙模块222与遥控器100内配置的蓝牙模块可实现遥控器与显示设备的蓝牙配对连接。
图15中示例性示出了根据一些实施例的显示设备与遥控器配对的操作提示展示方法的流程图。参见图15，本发明实施例提供的一种显示设备，在执行显示设备与遥控器配对的操作提示展示方法时，其控制器被配置为执行下述步骤：
S1、通过蓝牙模块接收遥控器产生的配对信号。
为适应不同的应用场景，显示设备的控制器内仅配置一种运行模式，即商场模式或用户模式。因此，在启动显示设备以后，相应显示设备会运行指定运行模式下的相关程序。例如，在商场模式下，在用户或导购员需要用遥控器与显示设备建立蓝牙配对连接，以向其他用户展示语音功能时，用户或导购员可触发遥控器上配置的任一按键，产生配对信号。
为避免一个遥控器使用语音功能时影响多个显示设备，蓝牙配对功能限制在一个蓝牙遥控器仅支持配对一台显示设备。在商场模式下，遥控器作为主设备，在触发配对流程后，可能会有多台显示设备收到配对信号，为建立一对一的蓝牙配对连接，可选取距离遥控器最近的显示设备首先与遥控器建立连接，完成配对。
在一些实施例中，控制器在执行通过蓝牙模块接收遥控器产生的配对信号，被进一步配置为执行下述步骤：
步骤11、通过蓝牙模块接收遥控器产生的配对请求。
步骤12、响应于配对请求，发送携带距离信息的反馈信号至遥控器，距离信息用于表征显示设备与遥控器之间的距离，遥控器用于响应于反馈信号，确定距离信息对应的距离最小的显示设备为目标配对显示设备；
步骤13、接收遥控器响应于反馈信号确定出目标配对显示设备后生成的配对信号。
用户触发遥控器的任一按键产生配对请求，在商场模式下，在与遥控器相距10-30厘米内的显示设备均可接收到该配对请求；在用户模式下，与遥控器相距3-6米内的显示设备可接收到该配对请求。但由于用户模式通常仅会设置一台显示设备，可实现遥控器与显示设备的一对一的蓝牙配对连接。因此，此处仅针对在商场模式下建立遥控器与显示设备的一对一的蓝牙配对连接的情况。
在商场模式下，每个能够接收到遥控器发送的配送请求的显示设备，在接收到配对请求后，均发送携带距离信息的反馈信号至遥控器，该距离信息可标识对应显示设备与遥控器之间的距离。
遥控器在接收到每个显示设备发送的反馈信号后，即可对多个距离信息进行排序，选取距离信息对应的距离最小的显示设备为目标配对显示设备，在确定出目标配对显示设备后，遥控器即可生成配对信号，并将配对信号发送至目标配对显示设备，建立一对一的蓝牙配对连接。
S2、响应于配对信号，查找蓝牙模块的配置位置，配置位置是指蓝牙模块相对于显示器的物理位置。
接收到配对信号的显示设备，查找其配置蓝牙模块的配置位置，以确定蓝牙模块相对于显示器所处的物理位置。
图16中示例性示出了根据一些实施例的蓝牙模块的配置位置的示意图。不同的显示设备的蓝牙模块的配置位置不同，通常可配置在图16中所示的10个位置。
控制器接收到遥控器发送的配对信号后，即可与显示设备的主板进行通信，主板中配置有蓝牙模块的位置信息，例如，蓝牙模块位于显示器的上侧、下侧、左侧、右侧等。控制器在获取到位置信息后，即可确定出蓝牙模块的配置位置，即位于图16中所示10个位置的目标物理位置。
确定出的蓝牙模块的配置位置所对应的显示器的位置用于以动画的形式显示配对 操作提示，便于用户得知蓝牙模块的位置，以高效的完成遥控器与显示设备的连接。
S3、基于蓝牙模块的配置位置，生成配对操作提示，配对操作提示用于提示遥控器在与显示设备的预设距离范围内对准蓝牙模块的位置。
在确定出目标配对显示设备的蓝牙模考的配置位置后，即可生成配对操作提示，以提示用户应如何操作遥控器，以实现遥控器在预设距离范围内与显示设备的蓝牙配对连接。
为便于用户操作遥控器的移动方向，调整遥控器与显示设备之间的距离和方向，生成的配对操作提示中包括方位提示文本框和配对配置提示动画。
在一些实施例中，控制器在执行基于蓝牙模块的配置位置，生成配对操作提示，被进一步配置为执行下述步骤：
步骤31、获取蓝牙模块的配置位置的方位信息，方位信息是指蓝牙模块相对于显示器的方向位置。
步骤32、基于方位信息，生成方位提示文本框和配对位置提示动画，方位提示文本框用于提示遥控器在与显示设备的预设距离范围内便于对准蓝牙模块的位置所需移动的方向，配对位置提示动画用于提示蓝牙模块的物理位置。
控制器在向主板获取蓝牙模块的位置信息时，具体包括蓝牙模块的配置位置的方位信息，即蓝牙模块相对于显示器的方向位置，例如，位于显示的左上方、右上方、左侧、右侧、下侧等。
获取到蓝牙模块的方位信息后，即可基于方位信息生成方位提示文本框和配对位置提示动画，作为配对操作提示，以提示用户对遥控器的操作步骤。
图17中示例性示出了根据一些实施例的配对操作提示的显示示意图。参见图17，配对操作提示中的方位提示文本框用于提示遥控器在与显示设备的预设距离范围内便于对准蓝牙模块的位置所需移动的方向，例如，图17中所示的“请保持遥控器离显示设备左上方动画位置10cm范围内”。配对操作提示中的配对位置提示动画用于提示蓝牙模块的物理位置，例如，如图17中所示的位置，若蓝牙模块位于显示器的左上方，则在显示器的左上方蓝牙模块的所处位置显示提示动画，以告知用户蓝牙模块的位置，便于用户调整遥控器与蓝牙模块的距离和方向。
S4、将配对操作提示显示在显示器的用户界面中。
在生成配对操作提示后，即可将配对操作提示显示在用户界面的相应位置，即将方位提示文本框和配对配置提示动画分别显示在用户界面的相应位置，使得即使显示设备上未标示有用于标识蓝牙模块物理位置的丝印，用户仍可以进行高效的遥控器与显示设备的蓝牙配对连接。
在一些实施例中，控制器在执行将配对操作提示显示在显示器的用户界面中，被进一步配置为执行下述步骤：
步骤41、将方位提示文本框显示在用户界面的底部。
步骤42、基于蓝牙模块的配置位置，将配对提示动画显示在蓝牙模块相对于显示器的相应位置。
将方位提示文本框显示在用户界面的中间位置，如用户界面的底部，以便于用户的观看；将配对位置提示动画显示在蓝牙模块相对于显示器的所处位置，以告知用户蓝牙模块的位置，便于用户调整遥控器与蓝牙模块的距离和方向。
可见，本实施例提供的显示设备，提供一种友好的蓝牙遥控器配对显示设备展示提示的方法并配以微交互，配对操作交互引导性好，极大提升配对成功率，能够有效提升产品的用户体验水平。
利用本实施例提供的显示设备与遥控器进行配对连接时，从触发遥控器产生配对请求到显示器的用户界面中展示配对操作提示的用时，通常会控制在2秒以内，提高用户体验。且配对操作提示中的方位提示文本框和配对配置提示动画同时显示，同时消失。
在用户根据配对操作提示，完成目标显示设备与遥控器的蓝牙配对连接后，取消配对操作提示的显示。配对操作提示仅用于提示用户如何操作遥控器才能实现快速的与显示设备建立蓝牙配对连接，因此，配对操作提示一直持续显示直至遥控器与显示设备进入配对流程后消失。
由以上技术方案可知，本发明实施例提供的一种显示设备，控制器通过蓝牙模块接收遥控器产生的配对信号；响应于配对信号，查找蓝牙模块的配置位置，基于蓝牙模块的配置位置，生成配对操作提示；将配对操作提示显示在显示器的用户界面中，以提示用户遥控器在与显示设备的预设距离范围内对准蓝牙模块的位置时所需进行的操作。可见，本发明实施例提供的显示设备，由控制器基于遥控器的配对信号查找蓝牙模块的物理位置，将配对操作提示以动画的形式与蓝牙模块的物理位置映射，使得配对操作交互引导性好，实现高效的遥控器与显示设备的蓝牙配对连接。
图15中示例性示出了根据一些实施例的显示设备与遥控器配对的操作提示展示方法的流程图。参见图15，本发明实施例提供的一种显示设备与遥控器配对的操作提示展示方法，由上述实施例提供的显示设备中配置的控制器执行，所述方法包括：
