Fig. 5 is a schematic flowchart illustrating a broadcast source scanning method applied to a display device according to an embodiment of the present application, where as shown in fig. 5, the broadcast source scanning method according to an embodiment of the present application includes the following steps:

s51: when receiving a broadcast packet sent by a control device, a display device determines whether the broadcast packet includes a Universally Unique Identifier (UUID) of a broadcast assistant service.

For example, the user may determine whether the display device needs to be assisted by the control device to discover the broadcast source according to an actual application scenario. For example, in a scene that a broadcast source is relatively hidden, there are many obstructions between the broadcast source and the display device, the broadcast source is far away from the display device, the display device has a weak capability of scanning the broadcast source, or the display device has a functional failure of scanning the broadcast source, the user can assist the display device to discover the broadcast source by triggering the control device. The control device may be provided with a physical button or a virtual button, and a user may trigger the physical button or the virtual button to trigger the control device to assist the display device in discovering the broadcast source. Taking a virtual button as an example, as shown in fig. 6, fig. 6 is a schematic diagram of a display interface of the control device provided in the present application, where the display interface in fig. 6 includes: a broadcast assistant service button 601. When the user clicks the broadcast assistant service button 601, the control device is triggered to assist the display device to discover the broadcast source.

That is, a user may flexibly select whether to assist the display device to discover the broadcast source through the control device according to an actual application scenario, if necessary, the control device is triggered to assist the display device to discover the broadcast source, and if not, the display device may be selected to discover the broadcast source, thereby improving flexibility of a broadcast source scanning manner.

The user may also set the setting information of the control device so that the display device is assisted by the control device to discover the broadcast source in any scenario, for example, as shown in fig. 7, fig. 7 is a schematic diagram of another display interface of the control device provided in the present application, and the display interface in fig. 7 displays the setting information of the display control device, and may include: the broadcast assistant service switch 701 assists the display device to discover a broadcast source through the control device in any scene when the user sets the broadcast assistant service switch 701 to the on state.

That is, the user can assist the display device to discover the broadcast source through the control device subsequently through one-time setting operation without setting every time, thereby improving the convenience of assisting the display device to discover the broadcast source through the control device.

When it is determined that the display apparatus needs to be assisted by the control apparatus to discover the broadcast source, the control apparatus transmits a broadcast packet to the display apparatus. The broadcast packet may include: the UUID of the assistant service is broadcast. The UUID is used to indicate that the control device supports broadcast assistant services, i.e., the UUID may indicate that the control device has the capability to assist the display device in discovering the broadcast source.

In some embodiments, the broadcast packet may be a broadcast packet for requesting establishment of a bluetooth connection with the display device. In other embodiments, the broadcast packet may also be a broadcast packet dedicated to request establishment of a broadcast information link, as long as the broadcast packet carries the UUID of the broadcast assistant service.

In some embodiments, the broadcast packet may also carry information such as a device identifier of the Control device, a Media Access Control (MAC) address of the Control device, and the like.

S52: and the display equipment establishes a broadcast source information link with the control equipment under the condition that the UUID of the broadcast assistant service is determined to be included in the broadcast packet.

And when the display equipment determines that the broadcast packet comprises the UUID of the broadcast assistant service, the display equipment indicates that the control equipment supports the broadcast assistant service, and the display equipment and the control equipment establish a broadcast source information link so that the control equipment can send a broadcast source scanning result to the display equipment through the broadcast source information link.

S53: and the display equipment receives the broadcast source scanning result obtained by the control equipment through the broadcast source information link.

Since the control device supports the broadcast assistant service, the control device may be used to perform broadcast source scanning to obtain a broadcast source scanning result, where the broadcast source scanning result includes: at least one broadcast source. Due to the mobility of the control device, the control device can be moved to acquire more comprehensive broadcast source scanning results.

After the control device obtains the broadcast source scanning result, the control device sends the broadcast source scanning result to the display device through the broadcast source information link, and the display device receives the broadcast source scanning result obtained by the control device through the broadcast source information link.

Optionally, the broadcast source information link includes: generic attribute protocol GATT link or enhanced attribute protocol EATT link. And the control equipment sends the broadcast source scanning result to the display equipment through the GATT link or the EATT link.

Accordingly, the display device receives the broadcast source scanning result transmitted by the control device through the GATT link or the EATT link.

In this embodiment, the display device determines whether the broadcast packet includes a UUID of a broadcast assistant service, to determine whether the control device supports the broadcast assistant service, and establishes a broadcast source information link with the control device when determining whether the broadcast packet includes the UUID of the broadcast assistant service, and receives a broadcast source scanning result obtained by scanning a broadcast source by the control device through the broadcast source information link. According to the display device and the broadcast source scanning method provided by the embodiment of the application, under the condition that the control device supports the broadcast assistant service, the control device scans the broadcast source and sends the broadcast source scanning result obtained by scanning the broadcast source to the display device, so that the embodiment of the invention can obtain a more comprehensive broadcast source scanning result by utilizing the mobility of the control device, and the problem that the broadcast source which is required to be connected cannot be scanned due to the fact that the display device scans the broadcast source is solved.

As an extension and refinement of the foregoing embodiment, the broadcast source scanning result may be obtained through, but not limited to, the following possible implementation manners, where reference is made to fig. 8 for one of the possible implementation manners, and another broadcast source scanning method provided in the embodiment of the present application is, as shown in fig. 8, fig. 8 is a description of one possible implementation manner of S53 on the basis of the embodiment shown in fig. 5:

s53a: and the display equipment periodically receives the broadcast source scanning result sent by the control equipment through the broadcast source information link.

After the broadcast source information link is established, the control device may periodically scan a broadcast source and send a broadcast source scanning result to the display device, and accordingly, the display device periodically receives the broadcast source scanning result sent by the control device through the broadcast source information link. The specific period may be set by the user according to a requirement, for example, the broadcast source scanning is performed every other minute, or the broadcast source scanning is performed every other hour, which is not limited in this embodiment of the present application.

In this embodiment, the control device periodically scans the broadcast source and periodically sends the broadcast source scanning result to the display device through the broadcast source information link, so that the display device can periodically know the condition of the broadcast source.

Referring to fig. 9, another possible implementation manner of the broadcast source scanning method provided in the embodiment of the present application is shown in fig. 9, where fig. 9 is a description of another possible implementation manner of S53 on the basis of the embodiment shown in fig. 5:

s53b1: the display device receives a scanning trigger operation input by a user.

The user may input a scan trigger operation on the display device, where the scan trigger operation is used to trigger acquisition of a broadcast source scan result. Optionally, an entity button or a virtual button may be set on the display device, and the user may input the scan trigger operation by triggering the entity button or the virtual button corresponding to the function of obtaining the scanning result of the broadcast source, or the user may input the scan trigger operation by using a voice input method. As shown in fig. 10, fig. 10 is a schematic view of a display interface of a display device according to an embodiment of the present application, in fig. 10, a broadcast source scanning result obtaining button 1001 is displayed, and after the broadcast source scanning result obtaining button 1001 is triggered by a user, S53b2 is executed.

S53b2: and the display equipment sends request information for requesting the control equipment to carry out broadcast source scanning to the control equipment through the broadcast source information link.

After receiving the request information requesting the control device to perform broadcast source scanning, the control device performs broadcast source scanning to obtain a broadcast source scanning result, and sends response information carrying the broadcast source scanning result obtained by the broadcast source scanning to the display device through a broadcast source information link.

In some embodiments, the control device may execute the broadcast source scanning result obtained by the broadcast source scanning once every time the request information is received, and receive response information carrying the broadcast source scanning result obtained by the broadcast source scanning through the broadcast source information link.

In other embodiments, the request information may further carry a scanning period; the request information is used for instructing the control equipment to carry out broadcast source scanning in the scanning time period; that is, after receiving the request information, the control device performs scanning according to the scanning time period carried in the request information, and receives, through the broadcast source information link, response information carrying a broadcast source scanning result obtained by performing broadcast source scanning in the scanning time period.
