The controller 210 of the display device 200 provided in this embodiment is configured with an Andriod system to support the running of each application on the display device 200 and control the operation of each hardware.

Referring to fig. 10 and 11, the Andriod system shown in this embodiment is configured with an application layer, a Java layer, and a Native layer, where the Java layer and the Native layer communicate with each other through a communication Interface such as JNI (Java Native Interface) or HIDL (Hardware Interface definition Language).

In the Android system, an audio policy Service (AudioPolicy Service) is generally configured on the local layer to manage the audio output policy of the display device 200, and a large part of the AudioPolicy Service management is performed in the AudioPolicy manager, including volume management, audio policy (Strategy) management, and input/output device management. Therefore, in this embodiment, a customized customer service (customer service module) is further set in the audiopolicymarvice, and the customer service inherits the AudioPolicyManager class, and completes the instantiation thereof when the AudioPolicyManager is initialized.

In the Andriod system shown in fig. 10, the Customeservice inherits the AudioPolicy Manager, so that a method of covering a parent class in the Customeservice can be implemented, and customization of functions is realized. The Customeservice communicates with the JNI shared library through the binder upwards, and the JNI shared library packages JAVA static library supply application layer calls upwards.

In the Android system shown in fig. 11, unlike fig. 10, the Android system provided in fig. 11 implements communication between the application layer and the local layer in a HIDL manner.

Through the JNI interface or the HIDL interface, the system application and the third-party application of the application layer can conveniently and quickly call the client service module so as to realize the control and selection of the sound output equipment. In addition, the application of the application layer realizes the real-time update of the state of the sound output equipment by registering the callback function in the client service module.

Referring to fig. 12, in the present embodiment, after the display device 200 is powered on (including ac power on and STR power on), the customer service module is specifically configured to perform the following.

First, in response to receiving a broadcast indicating that the display apparatus 200 is booted (bootcomplete) and a broadcast indicating that the display 280 is turned on (ScreenOn), the connection states and sound output modes of all the sound output apparatuses connected to the display apparatus 200 are updated. Wherein the sound output mode is determined according to the setting before the display apparatus 200 is turned off.

Specifically, the customer service module may determine the connection status of the sound output Devices through a global variable mAvailableOutput Devices of the AudioPolicyManager, which records all output peripherals of the current local layer connection (i.e., all external sound output Devices connected to the display device, such as headphones, etc.).

Next, the current sound output mode of the display apparatus 200 is determined.

Note that, in the present embodiment, the sound output mode includes a no-headphone mode, a headphone-only mode, and a headphone and speaker mode. In the no-headset mode, the headset is disconnected from the display device 200 and the display 280 will display the option of headset mode when the headset is plugged into the display device 200. In the earphone-only mode, only an earphone may be used as a sound output device of the display device 200. In the earphone and speaker mode, both the earphone and the speaker can be used as sound output devices of the display device 200.

Subsequently, the operating device is determined according to the current sound output mode of the display device.

Specifically, if the current sound output mode is the no-earphone mode, the speaker is set as the working device when the earphone is not connected, and the speaker and the earphone are collectively set as the working device when the earphone is connected. If the current sound output mode is the earphone only mode, the speaker is set as the working device when the earphone is not connected, and the earphone is set as the working device when the earphone is connected. If the current sound output mode is the earphone and speaker mode, the speaker is set as the working device when the earphone is not connected, and the speaker and the earphone are set as the working device together when the earphone is connected.

In this embodiment, the customer service module sets the working device by changing the global variable mAudiosink. For example, when the client service module sets the Speaker as a working device, the mAudiosink is set as Speaker; when the earphone is set as a working device, setting the mAUDIOSINK as a Headphone; when the earphone and the loudspeaker are jointly set as working equipment, the mAUDIOSINK is set as Headphone + Speaker.

And finally, displaying the equipment states, the working states and the sound output modes of all the sound output equipment in a setting interface of the sound output equipment.

The embodiment provides a selection method of a sound output device based on a display device displaying a setting interface of the sound output device. Referring to fig. 13, the method is applied to a customer service module, and specifically includes the following steps S1301 and S1302.

Step S1301, in response to receiving a device selection instruction input by the user on the setting interface, the customer service module sets the sound output device indicated by the device selection instruction as a working device, and displays a device option of the sound output device in a selected state on the setting interface.

In step S1302, the customer service module sets other sound output devices as non-working devices, and displays device options of the other sound output devices in an unselected state on the setting interface.

Further, after the sound output device is newly connected or removed in the display device 200, the customer service module changes the device state of the sound output device by an operation in which an option is highlighted to be selectable when the device is connected and is not selectable when the device is disconnected.

Illustratively, as shown in fig. 14, the client service module calls setDeviceConnectionState to change the state of the attached or removed sound output device.

Specifically, after detecting that a device is connected or removed, the customer service module first determines whether the device is a sound output device. If so, the device state of the sound output device is judged to be connected or disconnected. If the device state is connected, the setDeviceConnectionState in the AudioPolicyManager is called by addOutputDevice to change the state of the device. If the device state is disconnected, the state of the device is changed by calling setDeviceConnectionState in AudioPolicyManager through rmOutputDevice.

In one example, referring to fig. 15, addOutputDevice is configured to perform the following operations.

Firstly, judging whether the accessed sound output equipment is effective sound output equipment or not; if not, the operation ends; if yes, further judging whether the earphone is the earphone. If the current sound output mode is the earphone mode, the current sound output mode is set to the earphone only mode; if the sound output device is not a headphone, the sound output mode is changed to a headphone and speaker mode when the sound output mode is a headphone-only mode.

Next, the current sound output mode of the display apparatus 200 is determined.

Subsequently, the operating device is set according to the sound output mode. Specifically, if the current sound output mode is the earphone-less mode, the working Device will be set according to the parameter (e.g. Device); if the current sound output mode is an earphone-only mode, setting the earphone as working equipment; if the current sound output mode is the earphone and speaker mode, the earphone and speaker are simultaneously set as the working devices.

And finally, displaying a setting interface according to the currently working sound output equipment.

In another example, referring to fig. 16, a rmOutputDevice (device removal interface) is configured to perform the following operations.

First, it is determined whether the removed sound output apparatus is a valid sound output apparatus. If not, the operation ends. And if the equipment is the valid equipment, judging whether the equipment is the earphone or not. If it is a headphone, the display apparatus 200 is set to a no-headphone mode.

Subsequently, the current sound output mode of the display device is judged.

And finally, selecting new working equipment according to the current sound output mode. Specifically, if the current sound output mode is the headphone-only mode, the headphones are set as the working devices. If the current sound output mode is the headphone-less mode, or the headphone and speaker mode, a new working device is selected according to the choposeDeviceBy Priority in the calling customer service module (device interface is selected according to Priority).

In one specific example, referring to fig. 17, the zoosedevicebypriority is configured to perform the following operations. It should be noted that the priority of the sound output device is determined according to a preset configuration, which is not limited in the present embodiment.

First, all currently active sound output devices of the display device 200 are determined.

Secondly, whether all the effective sound output devices have Bluetooth devices or not is judged. And if so, setting the Bluetooth device as the working device. If not, the next step is performed.

Subsequently, it is determined whether there is an ARC device among all the valid sound output devices. And if the ARC device exists, setting the ARC device as a working device. If not, the speaker is set as the working device.

In addition, the client service module is also provided with setHeadphoneMode (set sound output mode interface) for switching the working mode of the earphone according to the user instruction.

In one example, as shown in fig. 18, setHeadphoneMode determines the type of the sound output mode selected by the user in response to receiving a sound output mode selection instruction input by the user at the setting interface. If the sound output mode is the earphone only mode, the earphone is set as the working device, and the updateAudioOutput interface is called to change the sound output mode of the display device 200. If the sound output mode is the earphone and speaker mode, the speaker is set as the working device, and the updateAudioOutput interface is called to change the sound output mode of the display device 200.

Specifically, as shown in fig. 19, the updataaudiooutput interface first calls add output device to detect whether the global variable mAudiosink changes. If the mAUDIOSINK is not changed, the sound output device is not changed, and the program is ended. If the change of the global variable mAUDIOSINK is detected, firstly, the state of the Bluetooth device is checked, the output devices of all strategies are checked, and the states and output ports of all devices are updated. Subsequently, getDeviceForStrategy in the client service module is called (according to the policy get device interface) to determine the working device. And finally, controlling to open the working equipment and reporting the information to the application layer.

Referring to fig. 20, getdeviceforstrutegy (according to policy acquisition device interface) is configured to determine whether the sound output mode setting is the headphone and speaker mode. If so, the earphone is not set as an output device, for example, maudiosissink & -headset is set. If not, the setting is not changed, for example, maudiosisink is set.

Through the display equipment that this embodiment provided above, the user can directly switch target sound output equipment through sound output equipment's setting interface to set up the mode of this equipment, it is easy and simple to handle, have better user experience. In addition, the display device can display the device states, the working states and the working modes of all the sound output devices in the setting interface, so that a user can intuitively know the states of the sound output devices.
