However, some audio devices on the market (such as soundbars) fail to strictly adhere to the CEC protocol due to cost-saving measures or design limitations. These audio devices often cannot respond to messages initiated by the TV in a timely manner. As a result, in many scenarios where downstream serial signal sources of these audio devices are connected to the TV, the serial link between the TV and the serial signal source of the audio device cannot be restored, making it impossible for the TV to successfully output audio and video and preventing the TV from remotely controlling the serial signal source.

[0022] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments provided herein are merely illustrative of the present disclosure and are not intended to limit the present disclosure. Furthermore, the embodiments provided below are some embodiments for implementing the present disclosure, and not all embodiments for implementing the present disclosure. Unless otherwise specified, the technical solutions described in the embodiments of the present disclosure can be implemented in any combination.

[0023] It should be noted that, in the embodiments of this disclosure, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a method or apparatus that includes a list of elements includes not only the elements expressly described, but also other elements not expressly listed, or elements inherent to implementing the method or apparatus. Without further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other related elements (e.g., steps in the method or units in the apparatus; for example, a unit may be a portion of circuitry, a portion of a processor, a portion of a program or software, etc.) in the method or apparatus that includes that element.

[0024] For example, the link recovery processing method provided in this embodiment includes a series of steps, but the link recovery processing method provided in this embodiment is not limited to the steps described. Similarly, the link recovery processing apparatus provided in this embodiment includes a series of units, but the apparatus provided in this embodiment is not limited to the units explicitly described, but may also include units that need to be set up for obtaining relevant information or processing based on information.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0026] It is understood that in the specific implementation of this application, related data is involved. When the embodiments in this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of related data must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0027] Currently, interconnection between smart TVs and third-party audio devices (such as soundbars) is mainly achieved through the HDMI interface and its CEC (Consumer Electronics Control) protocol. However, some audio devices on the market (such as soundbars) fail to strictly adhere to the CEC protocol due to cost-saving measures or design limitations. These audio devices often cannot respond to messages initiated by the TV in a timely manner. As a result, in many scenarios where downstream serial signal sources of these audio devices are connected to the TV, the serial link between the TV and the serial signal source of the audio device cannot be restored, making it impossible for the TV to successfully output audio and video and preventing the TV from remotely controlling the serial signal source.

[0028] To address these issues, this application provides a link restoration processing solution. In many predetermined link restoration scenarios where a serial signal source downstream of an audio device is connected to a television, the solution can reliably enable the television to automatically restore the serial link between itself and the audio device and the serial signal source, ensuring that the television successfully outputs audio and video and that the television can successfully perform remote control linkage with the serial signal source.

[0029] The following is a detailed description of the relevant embodiments of the link recovery processing scheme provided in this application.

[0030] Figure 1 A flowchart illustrating a link restoration processing method according to an embodiment of this application is shown. The entity executing this link restoration processing method can be a television (TV) with processing capabilities. The TV is connected to an audio device, which is connected to a serial signal source. The specific connection method can be wired or wireless, and this application does not specifically limit this. The serial signal source is a signal source connected to the TV via an intermediate audio device, such as a Blu-ray player, set-top box, game console, TV box, etc.

[0031] like Figure 1 As shown, the link recovery processing method may include steps S110 to S130.

[0032] Step S110: In the predetermined link recovery scenario, retrieve the attribute field used to record the physical address of the serial information source locally; Step S120: If an attribute field is retrieved, a source recovery setting message carrying the attribute field is generated; Step S130: Send the source recovery setting message to the audio device to wake up the audio device and activate the serial source.

[0033] The pre-defined link recovery scenario is a scenario in which the TV needs to automatically restore the serial link between the TV and the serial signal source of the audio device. The pre-defined link recovery scenario includes, but is not limited to, the scenario of the TV starting up after a power outage, the scenario of the TV starting up after a standby period, the scenario of the TV being triggered to switch signal sources, and the scenario of the TV restarting.

[0034] Before the TV enters the predetermined link recovery scenario, the TV can record the physical address corresponding to the serial source of the audio device in the attribute field defined locally (i.e., the TV operating system). This attribute field is persistent (it will not be cleared even if the TV is powered off). This attribute field can be described as the LPA (last_deviceselect_physicaladdress) field.

[0035] In this predetermined link restoration scenario, the television can first retrieve the attribute field used to record the physical address of the serial signal source locally (i.e., the television operating system). If the attribute field is found, a signal source restoration setting message carrying the attribute field (i.e., a signal source restoration setting message carrying the physical address) is directly generated. This signal source restoration setting message can wake up the audio device and instruct the audio device to activate the serial signal source corresponding to the physical address carried therein.

[0036] Sending a source recovery setting message to the audio device allows the audio device to be actively woken up and activated based on the physical address, even if the audio device fails to strictly follow the CEC protocol. This is because the source recovery setting message carries the physical address. As a result, the audio device can be automatically restored to the serial link between the TV and the audio device and the serial source without the user having to manually adjust the audio device or TV.

[0037] Through the serial link, the serial source can successfully transmit audio and video to the audio device, and the audio device can further successfully transmit video to the TV, ensuring that the TV successfully outputs video and the audio device successfully outputs audio; the TV can also successfully transmit remote control commands (CEC commands) to the serial source through the serial link, ensuring that the TV can successfully perform remote control linkage with the serial source.

[0038] In summary, using the method described in this embodiment, in a predetermined link recovery scenario, the television first retrieves the attribute field used to record the physical address of the serial signal source locally; if the attribute field is found, a signal source recovery setting message carrying the attribute field is generated; the television sends the signal source recovery setting message to the audio device. Even if the audio device fails to strictly follow the CEC protocol, since the signal source recovery setting message already carries the physical address, the audio device can be directly woken up to successfully activate the serial signal source, reliably realizing the automatic restoration of the serial link between the television and the serial signal source of the audio device, ensuring that the television successfully outputs audio and video and ensures that the television can successfully remotely control the serial signal source.

[0039] The following description Figure 1 Further optional specific embodiments for each step performed during link recovery processing in the example implementation.

[0040] In one embodiment, before "step S110 in the predetermined link recovery scenario, retrieving the attribute field for recording the physical address of the contiguous signal source locally", the method may further include: receiving routing information returned by an audio device, wherein the audio device returns routing information to the television when triggering a predetermined signal source switching operation; obtaining the physical address of the contiguous signal source from the routing information; and recording the physical address in the attribute field.

[0041] When the audio device triggers a predetermined source switching operation, it returns routing information to the television, which carries the physical address of the aforementioned concatenated source. The television parses this routing information to obtain the physical address of the concatenated source and records it in an attribute field. Thus, the television can automatically record the physical address of the concatenated source in the attribute field, thereby successfully restoring the concatenated link with the audio device and the concatenated source based on the steps in the aforementioned embodiments.

[0042] The predetermined source switching operation can be a user-initiated switching to the cascaded source triggered by the audio device, or it can be an automatic switching to the cascaded source triggered by the audio device.

[0043] Furthermore, in one embodiment, before receiving the routing information returned by the audio device, the method may further include: sending a serial source switching message to the audio device; if no source switching response information is received from the audio device, then performing a preset operation to trigger a predetermined source switching operation on the audio device.

[0044] When a television receives a command to switch to a contiguous source (such as a command sent by the user to the television via remote control), the television can send a contiguous source switching message to the audio device (such as a routing change message that does not carry the physical address of the contiguous source). This contiguous source switching message may not include the physical address of the contiguous source. If the audio device, upon receiving this contiguous source switching message, fails to strictly adhere to the CEC protocol due to cost-saving measures or design limitations, it will not respond to the contiguous source switching message and will not send subsequent source switching response information back to the television.

[0045] If the television detects that it has not received a source switching response from the audio device, it can perform a preset operation to trigger a predetermined source switching operation on the audio device. When the predetermined source switching operation is triggered on the audio device, the audio device can interact with the concatenated source to activate it, and the audio device will return routing information carrying the physical address of the concatenated source to the television. For example, one preset operation performed by the television could be a "playback prompt message" prompting the user to manually trigger the predetermined source switching operation to the concatenated source on the audio device.

[0046] In one embodiment, generating the source recovery setting message carrying attribute fields in step S120 may include: generating a route change message carrying attribute fields and / or a stream path setting message carrying attribute fields; correspondingly, sending the source recovery setting message to the audio device includes: sending the route change message and / or the stream path setting message to the audio device.

[0047] When the television retrieves the attribute field, it generates a routing change message (i.e., a RoutingChange message) and / or a set stream path message (i.e., a Set Stream Path message) carrying the attribute field. The Routing Change message and Set Stream Path message are message types defined in the CEC protocol. Sending the Routing Change message and / or Set Stream Path message, which carry the attribute field recording the physical address of the concatenated source, as a source restoration setting message to the audio device allows for direct and proactive wake-up of the audio device and enables the audio device to activate the corresponding concatenated source based on the physical address.

[0048] In one embodiment, after sending the source recovery setting message to the audio device in step S130 to wake up the audio device and activate the serial source, the method may further include: obtaining the source identification information of the serial source; and updating the source identification information in the source maintenance parameters.

[0049] The system obtains the source identification information of the serial source (such as the serial source identifier or physical address), updates the source identification information in the source maintenance parameters (i.e., the mActiveSource parameter), and then the TV can determine that the serial source is an activated signal source. This further ensures that the serial source can successfully transmit audio and video to the audio device, and the TV can successfully output the video.

[0050] In one embodiment, after sending the source recovery setting message to the audio device in step S130 to wake up the audio device and activate the serial source, the method may further include: clearing the attribute field in response to the source switching instruction to switch to a non-serial source; and sending a source switching message to the audio device to enable the audio device to activate the non-serial source.

[0051] A non-serial source is a signal source that is not connected to the television via an audio device. A non-serial source can be a signal source directly connected to the television. When a user sends a source switching command to the television to switch to a non-serial source, the television first clears the attribute field recording the physical address of the serial source. Then, the television sends a source switching message to the audio device, causing the audio device to activate the non-serial source. Clearing the attribute field avoids conflicts with non-serial scenarios. Therefore, a non-serial source can transmit video to the television for output, transmit audio to the audio device for output, or transmit audio to the television and have the television transmit the audio to the audio device for output.

[0052] Furthermore, in one embodiment, after retrieving the attribute field for recording the physical address of the serial signal source locally in step S110, the method may further include: if the attribute field is not found, sending a normal signal source setting message to the audio device to cause the audio device to perform normal signal source switching logic.

[0053] If the attribute field is not found, a standard source setting message (such as a routing change message without carrying the physical address of the concatenated source) is sent to the audio device. This allows the audio device to execute standard source switching logic to activate the concatenated source. The standard source switching logic refers to the logic described in this application. Figure 1 Other conventional activation logic besides the source activation logic shown in the steps of the embodiment. For example, when the audio device executes ordinary source switching logic, it may specifically include the audio device interacting with the serial source to obtain the physical address of the serial source, and further activating the serial source based on the physical address.

[0054] To facilitate better implementation of the link recovery processing method provided in the embodiments of this application, the steps in the foregoing embodiments are further described below in conjunction with a source switching scenario. In this source switching scenario, some of the foregoing embodiments of this application are applied for source switching. (See reference...) Figure 2 In this information source switching scenario, the information source switching process may include steps S210 to S2160.

[0055] Step S210: Send a command to the TV to switch to a serial signal source (such as a command sent by the user to the TV via a remote control to switch to a serial signal source).

[0056] In step S220, the television sends a serial source switching message (such as a routing change message that does not carry the physical address of the serial source) to the audio device.

[0057] In step S230, the user manually triggers a predetermined source switching operation on the audio device. For example, if the TV does not receive a source switching response from the audio device, a preset operation is performed to trigger the predetermined source switching operation on the audio device.

[0058] In step S240, the audio device can interact with the serial signal source to activate it. For example, the audio device interacts with the serial signal source to obtain its physical address and further activates it based on that address. For instance, Figure 2 The external signal sources shown may include serial signal sources.

[0059] In step S250, the audio device sends routing information carrying the physical address of the serial source back to the television, that is, the television receives the routing information returned by the audio device.

[0060] In step S260, the TV obtains the physical address of the serial signal source from the routing information and records the physical address in the attribute field.

[0061] In step S270, the serial signal source can successfully transmit audio and video to the audio device, and the audio device can further successfully transmit video to the TV, ensuring that the TV successfully outputs video and the audio device successfully outputs audio.

[0062] In step S280, the TV enters a predetermined link recovery scenario. The predetermined link recovery scenario includes, but is not limited to, the scenario where the TV is powered off and then powered on again, the scenario where the TV is in standby mode and then powered on again, the scenario where the TV is triggered to switch signal sources, and the scenario where the TV restarts.

[0063] Step S290: Retrieve the attribute field used to record the physical address of the concatenated source locally; if the attribute field is found, generate a source recovery setting message carrying the attribute field (such as a routing change message (i.e., a routing change message) carrying the attribute field that records the physical address of the concatenated source and / or a set stream path message (i.e., a set stream path message)); send the source recovery setting message to the audio device to wake up the audio device and activate the concatenated source.

[0064] In step S2100, the audio device automatically switches to the serial signal source, and the audio device can display relevant information about the serial signal source.

[0065] In step S2110, the audio device activates the serial signal source according to the physical address in the signal source recovery setting message.

[0066] In step S2120, the serial signal source can successfully transmit audio and video to the audio device, and the audio device can further successfully transmit video to the TV, ensuring that the TV successfully outputs video and the audio device successfully outputs audio.

[0067] In step S2130, the user sends a source switching command to the television to switch to a non-serial source.

[0068] In step S2140, in response to the source switching instruction to switch to a non-serial source, the television clears the attribute field and sends a source switching message to the audio device.

[0069] Step S2150: The audio device activates a non-serialized signal source.

[0070] In step S2160, the non-serial source can transmit the image to the television for output.

[0071] In this scenario, source switching is performed using the aforementioned embodiments of this application. In a predetermined link recovery scenario, the TV first retrieves the attribute field used to record the physical address of the serial source locally. If the attribute field is found, a source recovery setting message carrying the attribute field is generated. The TV sends the source recovery setting message to the audio device. Even if the audio device fails to strictly follow the CEC protocol, since the source recovery setting message carries the physical address, the audio device can be directly woken up to successfully activate the serial source. This reliably realizes the automatic restoration of the serial link between the TV and the audio device's serial source, ensuring that the TV successfully outputs audio and video and successfully remotely controls the TV with the serial source.

[0074] In some embodiments of this application, when generating the source recovery setting message carrying the attribute field, the message generation module can be used to: generate a route change message carrying the attribute field and / or a set flow path message carrying the attribute field; correspondingly, when sending the source recovery setting message to the audio device, the message sending module can be used to: send the route change message and / or the set flow path message to the audio device.

[0076] In some embodiments of this application, before receiving the routing information returned by the audio device, the device further includes a switching processing module that can be used to: send a serial source switching message to the audio device; if no source switching response information is received from the audio device, perform a preset operation to trigger the predetermined source switching operation on the audio device.

[0077] In some embodiments of this application, after sending the source recovery setting message to the audio device to wake up the audio device and activate the serial source, the device further includes a non-serial source switching module that can be used to: clear the attribute field in response to a source switching instruction to switch to a non-serial source; and send a source switching message to the audio device to enable the audio device to activate the non-serial source.

[0078] In some embodiments of this application, after the source recovery setting message is sent to the audio device to wake up the audio device and activate the serial source, the device further includes a source maintenance module for: obtaining source identification information of the serial source; and updating the source identification information in the source maintenance parameters.

[0079] In some embodiments of this application, after retrieving the attribute field for recording the physical address of the serial signal source locally, the device further includes a normal switching module for: if the attribute field is not found, sending a normal signal source setting message to the audio device to cause the audio device to perform normal signal source switching logic.

[0081] Furthermore, embodiments of this application also provide a television, such as Figure 4 As shown, Figure 4 A block diagram of a television according to an embodiment of this application is shown, specifically: The television may include components such as a processor 401 with one or more processing cores, a memory 402 with one or more computer-readable storage media, a power supply 403, and an input unit 404. Those skilled in the art will understand that... Figure 4 The television structure shown does not constitute a limitation on the television and may include more or fewer components than illustrated, or combine certain components, or have different component arrangements. Wherein: The processor 401 is the control center of the television, connecting various parts of the computer device via various interfaces and lines. It performs various functions and processes data by running or executing software programs and / or modules stored in the memory 402, and by calling data stored in the memory 402.
