When the display device is connected to a bluetooth device, such as a bluetooth headset (BT headset) or a bluetooth Speaker (BT Speaker), the type of the bluetooth device identified by the display device may not match the actual type of the bluetooth device, for example, the type of the connected bluetooth Speaker is identified as a bluetooth headset, but the interaction between different bluetooth devices and the display device is different, for example, the bluetooth headset has the following characteristics:

only the wearer can receive the sound after the Bluetooth headset is connected, and when the output equipment of other external sound playing boxes outputs the sound, the output of the Bluetooth headset cannot be interfered, so that the sound output behavior of the Bluetooth headset and the sound output behavior of other external sound playing boxes are independent, namely if the display equipment is connected with the Bluetooth headset, the output equipment of the Bluetooth headset cannot be switched to the output equipment of other external sound playing boxes to prevent the Bluetooth headset from outputting the sound. Therefore, optionally, the interaction mode of the bluetooth headset and other output devices of the playback box is as follows: when the display equipment outputs the sound, the sound can be simultaneously output to the Bluetooth earphone and other output equipment of the external playing box, or only the sound can be output to the Bluetooth earphone. Other output devices of the playback box include output devices of the playback box configured in a display device such as ARC (ARC Return Channel) Speaker, Spdif (Sony/Philips Digital Interface), and an external output device connected to the display device, which are only for example and not for limitation.

And the characteristics of bluetooth speaker and bluetooth headset are completely different: the sound output by the Bluetooth sound box is played outwards, so that when other output equipment of the external sound box outputs sound, the output of the Bluetooth sound box is interfered, namely, only one output sound exists in the Bluetooth sound box and other output equipment of the external sound box at the same time, and if the output equipment of the external sound box is switched to other output equipment of the external sound box when the Bluetooth sound box outputs sound, the Bluetooth sound box is muted, and the sound is not output any more. Therefore, optionally, the interaction mode of the bluetooth speaker and other output devices of the playback box is as follows: when the display device outputs the sound, the display device can only output the sound to the Bluetooth sound box or only output the sound to other output devices of the playback box.

Thus, if the display device incorrectly identifies the actual type of the connected bluetooth device, the connected bluetooth device cannot perform a sound output action matching the type thereof.

The above is an application scenario of the embodiment of the present application, and the following is a method embodiment provided by the present application. Referring to fig. 2, fig. 2 is a flowchart of a method provided by an embodiment of the present application. As an example, the flow shown in fig. 2 may be applied to a display device. The display device includes a television, a computer, and other electronic devices, and is not particularly limited in the embodiments of the present application.

As shown in fig. 2, the process may include the following steps:

step 201, identifying a first device type of a currently connected bluetooth device and displaying the first device type.

In specific implementation, when the display device is connected to the bluetooth device, the display device scans and analyzes Cod written in the bluetooth device, where Cod is set by a bluetooth device manufacturer before the bluetooth device leaves a factory and is used to indicate a type of the bluetooth device, and the display device determines the type of the bluetooth device indicated by Cod as the type of the currently connected bluetooth device (denoted as a first device type).

Optionally, the Cod specification is defined by the bluetooth alliance, and the Cod includes Reserved for Service Classes, Major Device Classes, and Minor Device Classes. Wherein the Major Device Classes and the Minor Device Classes are used for identifying the Bluetooth Device types. Reserved for Service Classes are used to define the class of Service that a bluetooth device wishes to associate with a display device application. The display Device may recognize that the type of the bluetooth Device is the first Device type by reading a Major Device Class, a Minor Device Class, in the Cod of the connected bluetooth Device.

Alternatively, the first device type may be displayed via the "xx xxxxxx" field in the interface shown in FIG. 3.

Step 202, learning whether the first device type is consistent with the second device type of the currently connected actual bluetooth device, if so, executing step 203, and if not, executing steps 204 to 205.

In this embodiment, specifically, whether the first device type is consistent with the second device type of the currently connected actual bluetooth device may be determined according to the following method:

and if an externally input equipment switching instruction is received within the appointed time, determining that the first equipment type is inconsistent with a second equipment type of the currently connected actual Bluetooth equipment. The specified time may be set by a user, or may be configured time when the display device leaves a factory, where the externally input device switching instruction is specifically a device switching instruction input by the user when the user finds, through the display device, that the first device type identified by the display device is not consistent with the actual device type (denoted as the second device type) of the bluetooth device, for example, when the user finds that the first device type identified by the display device is a bluetooth headset BT headset, but the second device type of the actual bluetooth device is a bluetooth Speaker BT Speaker, the user inputs a device switching instruction for switching the bluetooth headset BT headset recognized by the display device to the bluetooth Speaker.

If an externally input equipment switching instruction is not received within the specified time, determining that the first equipment type is consistent with a second equipment type of the currently connected actual Bluetooth equipment; or, if an externally input type consistent instruction is received, determining that the first device type is consistent with a second device type of the currently connected actual Bluetooth device. In this embodiment, the type-consistent instruction input from the outside may be an instruction input by the user to confirm to use the bluetooth device when the user checks through the display device that the first device type identified by the display device is consistent with the actual device type (marked as the second device type) of the bluetooth device, and as shown in fig. 3, the user may determine that the first device type is consistent with the second device type of the currently connected actual bluetooth device by clicking a Connect button on an interface where the display device displays the bluetooth device type.

And 203, interacting with the currently connected actual Bluetooth device according to the second device type.

As an embodiment, taking an example that the first device type is a type for indicating a bluetooth headset BT headset, and the second device type is also a type for indicating a bluetooth headset BT headset, it can be seen that, when the first device type is consistent with the second device type, the first device type interacts with an actual bluetooth device currently connected according to the type of the bluetooth headset, and a specific interaction process will be described in detail in the following description of interaction between the bluetooth headset and the display device.

Step 204, the currently displayed first device type is switched to the second device type.

In specific implementation, when an externally input device switching instruction is received within a specified time, the first device type identified by the display device for the bluetooth device is switched to the second device type. Taking the first Device Type as a Type for indicating a bluetooth headset BT headset, and the second Device Type as a Type for indicating a bluetooth Speaker BT Speaker as an example, the user may click a "Change Device Type" option on the interface shown in fig. 3 through a remote controller or a touch screen, etc. within a specified time, and select a "BT Speaker" option in the popped up options, so as to switch the currently displayed first Device Type "BT headset" to the second Device Type "BT Speaker".

And step 205, interacting with the currently connected actual Bluetooth device according to the second device type. Here, taking the second device type as the type for indicating the bluetooth Speaker BT Speaker as an example, after the first device type "BT headset" in the display device is switched to the second device type "BT Speaker" in step 204, the display device may interact with the bluetooth device in a manner corresponding to the second device type "BT Speaker", and a specific interaction process will be described in detail in the following description of interaction between the bluetooth Speaker and the display device.

The flow shown in fig. 2 ends up so far.

In this embodiment of the application, through the process shown in fig. 2, when it is identified that the type of the currently connected bluetooth device (denoted as a first device type) is not consistent with the actual device type of the currently connected bluetooth device (denoted as a second device type), the first device type may be switched to the second device type, and interaction is performed with the currently connected actual bluetooth device according to the second device type, so that the bluetooth device performs a sound output behavior matched with the type of the currently connected actual bluetooth device.

The interaction between the bluetooth headset and the display device in the embodiment of the present application will be described as follows:

as an embodiment, when the second device type indicates a bluetooth headset BT headset type, the display device displays an icon corresponding to the bluetooth headset BT headset at a specified position in a currently displayed page, as shown in fig. 4, a volume bar of the display device is on the right side of the interface shown in fig. 4, where the volume bar is used to indicate a volume of sound output by the display device, and an icon is arranged above the volume bar, where the icon is the second device type, that is, the icon corresponding to the bluetooth headset;

meanwhile, as shown in fig. 5, in this embodiment, it is recognized that the current audio output mode is output through a configured TV Speaker, and when a mode in an earphone headset menu in a displayed Sound menu is headset only, the headset only (denoted as a first mode) is used to instruct a display device to use a bluetooth headset, and in this mode, the output of Sound through the TV Speaker is suppressed, and the output of Sound through the bluetooth headset is controlled; and when the mode in the headset phone menu is headset phone with speakers (marked as a second mode), the headset phone with speakers (marked as a second mode) is used for indicating that a Bluetooth headset and the TV Speaker are adopted, and controlling the Bluetooth headset and the TV Speaker to output sound simultaneously. Here, the Sound menu when the bluetooth device type in the display device is a bluetooth headset is shown in fig. 6, where the headset menu is highlighted and tunable in the interface.

Further, it can be known that the first mode in this embodiment is used to instruct to prohibit the display device from outputting sound through the playback box device used before the bluetooth device is connected, and to control the display device to output sound using the bluetooth headset; and a second mode for instructing the display device to output sound through the bluetooth headset and the playback case device used before the bluetooth device is connected.

The above is the interaction between bluetooth headset and the display device, and the following is the interaction between bluetooth speaker and the display device:

as an embodiment, when the second device type indicates a bluetooth Speaker type, the display device displays an icon corresponding to the bluetooth Speaker BT Speaker at a specified position in the currently displayed page, as shown in fig. 7, a volume bar of the display device is on the right side of the interface shown in fig. 7, where the volume bar is used to indicate a volume of sound output by the display device, and an icon is above the volume bar, where the icon is an icon corresponding to the second device type, that is, the bluetooth Speaker. Meanwhile, as shown in fig. 8, at this time, the headset menu of the Sound menu displayed by the display device is grayed out to indicate that the headset menu is prohibited from being adjusted, and the Dolby Atmos (Dolby panophor) of the Sound menu is grayed out to prohibit the adjustment, wherein the Dolby Atmos is a Sound effect corresponding to the bluetooth headset.

Further, as shown in fig. 9, BT Sound bar in fig. 9 is used to instruct the display device to control Sound output through the bluetooth Speaker BT Speaker, and to suppress Sound output by other Sound output modules than the bluetooth Speaker BT Speaker.

It should be noted that, if the option in fig. 9 is adjusted to another option other than BT Sound bar, for example, to TV Speaker, the display device will output Sound through the whole Speaker TV Speaker and suppress the output Sound of the bluetooth Speaker BT Speaker.

So far, the description is completed on the interaction between the bluetooth device and the display device when the second device type is the bluetooth speaker in this embodiment.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
