Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is used to describe the association relationship of associated objects, for example, it means that there can be three relationships between the associated objects before and after, for example, A and/or B can mean: A alone exists, A and B exist simultaneously, There are three cases of B alone. The character "/" in this document generally indicates that the related objects are "or".

The technical solutions of the embodiments of the present application can be applied to a low-power audio processing system. Low-power audio technology provides powerful Bluetooth capabilities, including: more efficient audio codec capabilities, the ability to transmit multiple audio streams simultaneously, new Bluetooth audio broadcast capabilities, and Bluetooth Low Energy's ability to transmit audio.

In low-power audio technology, low-power broadcast audio involves profiles and services such as Basic Audio Profile (BAP), Broadcast Audio Scan Service (BASS), etc.

Wherein, the broadcast audio scanning service involves a related process of discovering a broadcast source in a broadcast audio processing system. The broadcast audio processing system includes a broadcast audio sink (Broadcast Sink), a broadcast assistant (Broad Assistant) and a broadcast source (Broadcast Source). 1A and 1B illustrate two possible topologies for a broadcast audio processing system.

As shown in Figure 1A, the broadcast source and the broadcast assistant can be configured on different devices. For example, the broadcast audio receiver is a wireless Bluetooth headset, and a portable terminal device such as a mobile phone can be used as a broadcast assistant to synchronize the broadcast audio stream with a broadcast source such as a TV and a computer.

As shown in Figure 1B, the broadcast source and the broadcast assistant can be configured on the same device. For example, the broadcast audio receiver is a wireless Bluetooth headset, and a portable terminal device such as a mobile phone can be used as a broadcast assistant, and the broadcast audio stream can be synchronized with the portable terminal device, which is a broadcast source.

Generally speaking, the broadcast audio receiver and the broadcast source synchronize the broadcast audio data stream, and need to perform the operation of scanning to discover the broadcast source, and the scanning needs to consume a certain amount of power. However, broadcast audio receivers are generally battery-powered embedded devices, so the broadcast audio receiver requests the broadcast assistant to perform a scan for broadcast sources. Based on this, the broadcast audio receiver may also be referred to as a Scan Delegator.

When the broadcast assistant performs the scanning operation, if it finds a broadcast source, it sends the relevant information of the broadcast source to the broadcast audio receiver through the Add Source operation defined in BASS.

For privacy requirements, broadcast sources can use Resolvable Private Address (RPA) to prevent addresses from being tracked. In the case of a broadcast source using RPA, if the broadcast source re-enables the same broadcast audio data stream, the address of the broadcast source usually changes. Before and after the broadcast source re-enables the same broadcast audio data stream, or before and after the address of the broadcast source is changed under other circumstances, the broadcast assistant sends the broadcast source address and other related information to the broadcast audio receiver. Two broadcast source history records (Broadcast Receive State Characteristic) are generated. For example, the broadcast source can be identified by triple information [Address Type (Advertiser_Address_Type), Address (Advertiser_Address), Broadcast Set ID (Advertising Set ID, SID)]; if the address of the broadcast source changes from RPA_1 to address RPA_2, the broadcast source The following broadcast source history is generated in the audio sink:

(1) The broadcast source history corresponding to RPA_1: Address_Type, RPA_1, SID;

(2) Broadcast source history records corresponding to RPA_2: Address_Type, RPA_2, SID.

However, the above two historical records of broadcast sources actually correspond to the same broadcast source, thus causing a waste of storage space in the broadcast audio receiver.

The solutions provided in the embodiments of the present application are mainly used to solve at least one of the above problems.

In order to understand the features and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

An embodiment of the present application provides a method for processing broadcast source information, and the method can be applied to, or executed by, a broadcast audio receiver. Referring to Figure 2, the method includes:

S210, in the case where it is determined based on the received address-related information of the first broadcast source that the broadcast source history record of the first broadcast source is stored in the broadcast source record list, execute the execution for the first broadcast source based on the broadcast source history record of the first broadcast source. A related operation of a broadcast source.

Optionally, the address-related information of the first broadcast source may include information such as address type and address of the first broadcast source. Exemplarily, the address-related information of the first broadcast source may be information such as an address type, an address, and the like sent by the broadcast assistant when performing the operation of adding a broadcast source.

Optionally, the broadcast source record list may be used to save the broadcast source history records of each broadcast source. The broadcast source history record may include address-related information, time-related information, status information, and the like of the broadcast source.

Optionally, the relevant operation for the first broadcast source performed based on the broadcast source history record of the first broadcast source may include: adding or updating the address correlation of the first broadcast source in the broadcast source history record of the first broadcast source. information, time-related information or status information, etc.; based on the broadcast source history record of the first broadcast source, send feedback information for the first broadcast source, for example, send feedback information including the identifier of the broadcast source history record, etc.

Since the relevant operation for the first broadcast source is performed based on the broadcast source history record of the first broadcast source, when the address-related information of the first broadcast source is received multiple times before and after, the existing information in the broadcast source record list is multiplexed. , there is no need to create a new broadcast source history in order to perform the relevant operation.

Exemplarily, the above method may further include processing steps in the case where the broadcast source history record of the first broadcast source is not saved. Specifically, the above-mentioned method applied to a broadcast audio receiver may also include:

If it is determined based on the address-related information of the first broadcast source that the broadcast source history record of the first broadcast source is not stored in the broadcast source record list, a broadcast source history record containing address-related information is created in the broadcast source record list.

After the broadcast source history record is created, related operations for the first broadcast source may be performed based on the created broadcast source history record, such as sending feedback information.

In this embodiment of the present application, the address-related information of the first broadcast source may be sent by a broadcast assistant. The broadcast assistant may be configured on the same device or on a different device than the first broadcast source. Correspondingly, the embodiments of the present application also provide a method for processing broadcast source information that can be applied to a broadcast assistant, or in other words, the broadcast assistant executes it. As shown in Figure 3, the method may include:

S310, sending address-related information of the first broadcast source;

According to the above method for processing broadcast source information, when the broadcast audio receiver receives the address-related information of the first broadcast source, it will determine whether the first broadcast source is stored in the broadcast source record list based on the address information of the first broadcast source If there is a history record of the first broadcast source, then multiplex the broadcast source history record of the first broadcast source to perform related operations. Therefore, before and after the address of the first broadcast source changes, the broadcast audio receiver uses the same broadcast source history record to perform related operations, avoiding the situation of storing multiple broadcast source history records for the same broadcast source and reducing the waste of storage space.

In practical applications, the broadcast assistant may obtain address-related information of the first broadcast source based on the address used by the first broadcast source.

In some optional embodiments, the broadcast assistant may carry the address used by the first broadcast source in the address-related information.

Exemplarily, in the case where the first broadcast source uses the first RPA to communicate, the broadcast assistant may obtain the address-related information of the first broadcast source including the first RPA based on the first RPA, and then send the address of the first broadcast source. Related Information. Correspondingly, the method for processing broadcast source information applied to the broadcast audio receiver may further include:

If a broadcast source history record with the same Identity Resolving Key (IRK) corresponding to the first RPA is found in the broadcast source record list, it is determined that the broadcast source record list contains the broadcast source history of the first broadcast source Record.

In the embodiment of the present application, the broadcast source, the broadcast assistant, and the broadcast audio receiver may be bound in advance. For example, if the broadcast source enables the privacy function, the broadcast source, the broadcast assistant, and the broadcast audio receiver establish a binding (Bonded) relationship; or, the broadcast source, the broadcast assistant, and the broadcast audio receiver establish a binding relationship in an Out of Band (OOB) manner. Based on this, the broadcast audio receiver can obtain its corresponding IRK by parsing based on the first RPA of the broadcast source.

The broadcast audio receiver may search for the broadcast source history record of the same IRK corresponding to the first RPA by searching the broadcast source record list for the address that can resolve the IRK corresponding to the first RPA. The found broadcast source history record is the broadcast source history record of the first broadcast source.

It can be seen that by parsing the IRK corresponding to the RPA, even if the address of the RPA type used by the first broadcast source changes, the broadcast audio receiver can accurately identify the broadcast source history record of the first broadcast source in the broadcast record list.

Optionally, when the address-related information of the first broadcast source includes the first RPA, the above method may further include:

The second RPA in the address-related information in the broadcast source history record of the first broadcast source is modified to the first RPA.

Specifically, when the broadcast source history record of the first broadcast source is created, the address of the broadcast source at that time, such as the above-mentioned second RPA, will be recorded in the broadcast source history record. If the searched broadcast source history record of the same IRK corresponding to the first RPA contains the second RPA when the address-related information including the first RPA is received, the second RPA is modified to the first RPA to update the first broadcast The address of the source.

The following two examples are used to describe the implementation manner of the above-mentioned processing steps of searching for the broadcast source history record of the first broadcast source by parsing the IRK in a specific application scenario.

Example 1

In this example, the broadcast assistant and the first broadcast source are configured on different devices.

As shown in Figure 4, the processing method of broadcast source information includes:

S41: The first broadcast source enables the privacy function. When the first broadcast source enables the privacy function, the first broadcast source, the first broadcast assistant, the second broadcast assistant and the broadcast audio receiver establish a binding relationship. In some application scenarios, the first broadcast source, the first broadcast assistant, the second broadcast assistant, and the broadcast audio receiver may also pre-establish a binding relationship in an out-of-band manner.

S42: The first broadcast source configures a broadcast audio data stream, and uses the second RPA as a communication address.

S43: The first broadcast assistant performs an operation of adding a broadcast source, and sends the address-related information (random device address, second RPA, SID) of the first broadcast source to the broadcast audio receiver. The Random Device Address is a subdivision address type of RPA.

S44: The broadcast audio receiver creates a broadcast source history record Source_ID1 including the second RPA.

After the binding relationship is established, the broadcast audio receiver receives the address-related information of the first broadcast source for the first time. At this time, the broadcast source history record of the first broadcast source is not saved in the broadcast source record list. Therefore, the Broadcast Audio Receiver creates a Broadcast Source History Record Source_ID1 containing the second RPA.

S45: The broadcast audio receiver sends feedback information of the broadcast reception status to the first broadcast assistant based on the broadcast source history record Source_ID1.

In the event that the first broadcast assistant receives the feedback information, the first broadcast assistant assists the broadcast audio receiver to establish broadcast audio data stream synchronization with the first broadcast source.

S46: The broadcast audio receiver triggers to stop synchronization. For example, when the user performs an audio pause operation in the broadcast audio receiver, the broadcast audio receiver triggers a stop sync.

S47: In the case of triggering to replay the audio, the first broadcast source re-enables the broadcast audio data stream, and uses the first RPA as the communication address.

S48: The first broadcast assistant or the second broadcast assistant performs an operation of adding a broadcast source, and sends the address-related information (random device address, first RPA, SID) of the first broadcast source to the broadcast audio receiver.

That is to say, after the first broadcast assistant helps the broadcast source audio receiver and the first broadcast source to establish broadcast audio data stream synchronization, after the synchronization is interrupted, the first broadcast assistant can help the broadcast audio receiver and the first broadcast source to re-establish The broadcast audio data stream is synchronized, and other broadcast assistants can also help the broadcast audio receiver to re-establish the broadcast audio data stream synchronization with the first broadcast source.

S49: Based on the address-related information of the first broadcast source, the broadcast audio receiver searches the broadcast source record list for the address that can resolve the IRK corresponding to the first RPA, so as to find the broadcast source history record corresponding to the same IRK as the first RPA .

S410: In the case where the broadcast audio receiver finds the broadcast source history record corresponding to the same IRA as the first RPA (that is, the broadcast source history record Source_ID1 including the second RPA), determine that the first broadcast source is stored in the broadcast source record list The broadcast source history record of the first broadcast source is modified to the first RPA in the address-related information in the broadcast source history record of the first broadcast source.

S411: The broadcast audio receiver sends feedback information of the broadcast reception status to the first broadcast assistant or the second broadcast assistant that sends the address-related information based on the broadcast source history record Source_ID1.

It can be seen that in the case where the first broadcast source and the broadcast assistant are configured on different devices, according to the method of the embodiment of the present application, before and after the first broadcast source re-enables the broadcast audio data stream, the broadcast audio receiver can multiplex the same One broadcast source history record is used to perform related operations for the first broadcast source. In this way, the situation of storing multiple broadcast source history records for the same broadcast source can be avoided, and the waste of storage space can be reduced.

Example 2

In this example, the broadcast assistant is configured on the same device as the first broadcast source.

As shown in Figure 5, the processing method of broadcast source information includes:

S51: The first broadcast source enables the privacy function. In the case where the first broadcast source enables the privacy function, the first broadcast source (broadcast assistant) establishes a binding relationship with the broadcast audio receiver. In some application scenarios, the first broadcast source (broadcast assistant) and the broadcast audio receiver may also pre-establish a binding relationship in an out-of-band manner.

S52: The first broadcast source configures a broadcast audio data stream, and uses the second RPA as a communication address.

S53: The broadcast assistant performs an operation of adding a broadcast source, and sends the address-related information (random device address, second RPA, SID) of the first broadcast source to the broadcast audio receiver.

S54: The broadcast audio receiver creates a broadcast source history record Source_ID1 including the second RPA.

S55: The broadcast audio receiver sends feedback information of the broadcast reception status to the broadcast assistant based on the broadcast source history record Source_ID1.

In the event that the broadcast assistant receives the feedback information, the first broadcast source and the broadcast audio receiver establish a broadcast audio data stream synchronization.

S56: The broadcast audio receiver triggers to stop synchronization. For example, when the user performs an audio pause operation in the broadcast audio receiver, the broadcast audio receiver triggers a stop sync.

S57: In the case of triggering to replay the audio, the first broadcast source re-enables the broadcast audio data stream, and uses the first RPA as the communication address.

S58: The broadcast assistant performs an operation of adding a broadcast source, and sends the address-related information (random device address, first RPA, SID) of the first broadcast source to the broadcast audio receiver.

S59: Based on the address-related information of the first broadcast source, the broadcast audio receiver searches the broadcast source record list for the address that can resolve the IRK corresponding to the first RPA, so as to find the broadcast source history record corresponding to the same IRK as the first RPA .

S510: In the case where the broadcast audio receiver finds the broadcast source history record corresponding to the same IRA as the first RPA (that is, including the broadcast source history record Source_ID1 of the second RPA), determine that the first broadcast source is stored in the broadcast source record list The broadcast source history record of the first broadcast source is modified to the first RPA in the address-related information in the broadcast source history record of the first broadcast source.

S511: The broadcast audio receiver sends feedback information of the broadcast reception status to the broadcast assistant based on the broadcast source history record Source_ID1.

It can be seen that in the case where the first broadcast source and the broadcast assistant are configured on the same device, according to the method of the embodiment of the present application, before and after the first broadcast source re-enables the broadcast audio data stream, the broadcast audio receiver can multiplex the same One broadcast source history record is used to perform related operations for the first broadcast source. In this way, the situation of storing multiple broadcast source history records for the same broadcast source can be avoided, and the waste of storage space can be reduced.

In some optional implementations, the broadcast assistant may carry a first identity address (Identity address) corresponding to the address used by the first broadcast source in the address-related information.

Exemplarily, the method for processing broadcast source information applied to the broadcast assistant may further include:

If the first broadcast source uses the first RPA to communicate, obtain the corresponding first identity address according to the first RPA;

Based on the first identity address, address-related information of the first broadcast source is obtained. Exemplarily, the address-related information of the first broadcast source includes the first identity address.

Optionally, the first identity address belongs to a public identity address (Public Identity Address) or a random identity address (Random Identity Address).

The broadcast assistant can resolve the corresponding identity address based on RPA. If the broadcast assistant sends the identity address to the broadcast audio receiver, before and after the RPA of the first broadcast source changes, the address of the first broadcast source received by the broadcast audio receiver remains unchanged and is always the same identity address. Correspondingly, the method for processing broadcast source information applied to the broadcast audio receiver may further include:

If a broadcast source history record including the first identity address is found in the broadcast source record list, it is determined that the broadcast source record list of the broadcast source record contains the broadcast source history record of the first broadcast source.

According to the above manner, the broadcast audio receiver can directly use the first identity address to determine whether the broadcast source history record of the first broadcast source is stored in the broadcast source record list. There is no need to update the address of the first broadcast source in the broadcast audio receiver. The operation flow in the broadcast audio receiver can be simplified.

The following two examples are used to describe the implementation manner of the above-mentioned processing steps of the broadcast audio receiver directly using the first identity address to find the broadcast source history record of the first broadcast source in a specific application scenario.

Example three

As shown in Figure 6, the processing method of broadcast source information includes:

S61: The first broadcast source enables the privacy function. When the first broadcast source enables the privacy function, the first broadcast source, the first broadcast assistant, the second broadcast assistant and the broadcast audio receiver establish a binding relationship. In some application scenarios, the first broadcast source, the first broadcast assistant, the second broadcast assistant, and the broadcast audio receiver may also pre-establish a binding relationship in an out-of-band manner.

S62: The first broadcast source configures a broadcast audio data stream, and uses the second RPA as a communication address.

S63: The first broadcast assistant obtains the corresponding first identity address according to the second RPA; and obtains address-related information (address type, first identity address, SID) of the first broadcast source based on the first identity address. An operation of adding a broadcast source is performed, and address-related information (address type, first identity address, SID) of the first broadcast source is sent to the broadcast audio receiver.

S64: The broadcast audio receiver creates a broadcast source history record Source_ID1 including the first identity address.

After the binding relationship is established, the broadcast audio receiver receives the address-related information of the first broadcast source for the first time. At this time, the broadcast source history record of the first broadcast source is not saved in the broadcast source record list. Therefore, the broadcast audio receiver creates a broadcast source history record Source_ID1 containing the first identity address.

S65: The broadcast audio receiver sends feedback information of the broadcast reception status to the first broadcast assistant based on the broadcast source history record Source_ID1.

S66: The broadcast audio receiver triggers to stop synchronization. For example, when the user performs an audio pause operation in the broadcast audio receiver, the broadcast audio receiver triggers a stop sync.

S67: In the case of triggering to replay the audio, the first broadcast source re-enables the broadcast audio data stream, and uses the first RPA as the communication address.

S68: The first broadcast assistant or the second broadcast assistant obtains the corresponding first identity address according to the first RPA; and based on the first identity address, obtains address-related information (address type, first identity address, SID) of the first broadcast source ). An operation of adding a broadcast source is performed, and address-related information (address type, first identity address, SID) of the first broadcast source is sent to the broadcast audio receiver.

S69: Based on the address-related information of the first broadcast source, the broadcast audio receiver searches the broadcast source record list for the broadcast source history record of the first broadcast source, that is, the broadcast source history record including the first identity address.

S610: In the case where the broadcast audio receiver finds the broadcast source history record of the first broadcast source, that is, the broadcast source history record including the first identity address, the broadcast audio receiver sends the address-related information based on the broadcast source history record Source_ID1 to the sender of the address-related information. The first broadcast assistant or the second broadcast assistant sends feedback information of the broadcast reception status.

In the case where the first broadcast source enables the privacy function, the first broadcast source (broadcast assistant) establishes a binding relationship with the broadcast audio receiver. In some application scenarios, the first broadcast source (broadcast assistant) and the broadcast audio receiver may also pre-establish a binding relationship in an out-of-band manner.

S72: The first broadcast source configures a broadcast audio data stream, and uses the second RPA as a communication address.

S73: The broadcast assistant obtains the corresponding first identity address according to the second RPA; and obtains address-related information (address type, first identity address, SID) of the first broadcast source based on the first identity address. An operation of adding a broadcast source is performed, and address-related information (address type, first identity address, SID) of the first broadcast source is sent to the broadcast audio receiver.

S710: In the case where the broadcast audio receiver finds the broadcast source history record of the first broadcast source, that is, the broadcast source history record including the first identity address, the broadcast audio receiver sends a broadcast reception to the broadcast assistant based on the broadcast source history record Source_ID1 Status feedback.
