Description

Technical Field

[0001] The present invention mainly relates to the technical field of audio and video output, and in particular to an audio routing method, device and electronic equipment. Background Art

[0002] With the development of technology, smart devices have more and more uses and more and more complex functions. The audio and video output of smart devices is not limited to a single video output and a single audio output. For example, some smart devices include multiple sub-screens and sub-speakers in addition to the main display and main speaker. A smart device can be connected to multiple screens and can display different content on multiple screens according to the user's intention. Each screen can also be equipped with a corresponding speaker to output the corresponding audio content; of course, the display and speaker can also output related content independently.

[0003] Smart devices have penetrated into various application fields, and multi-video and multi-audio outputs are becoming more and more popular. There are more and more requirements for a smart device to take into account different scenarios at the same time. For example, smart devices in catering stores include counter hosts, door advertising screens, kitchen notification speakers, lobby broadcast speakers, and voice prompt speakers for each table, etc. Users of smart devices need to play different audio content for different speakers at different times or at the same time.

[0004] In the existing general audio routing strategy, audio output is achieved by specifying an audio output device, but this method can only specify a single native audio output device, and cannot specify output to a custom audio output device (an audio output device added later). There are also methods in the related art for configuring custom audio output devices and corresponding routing rules, but this configuration method can only configure a known number of audio output devices, that is, the number of added custom audio output devices is fixed, and cannot be configured for audio systems with an unfixed number or a dynamically changeable number. Therefore, the relevant audio routing strategy or routing control method cannot adapt to the audio output situation when the audio output device is uncertain. Summary of the invention

[0034] Embodiment 1

[0035] Figure 1 FIG. 1 is a flow chart of an audio routing method according to an embodiment of the present invention. Figure 1 , the method 100 comprises:

[0036] S110, receiving an output request for an audio signal; wherein the audio signal includes an independent audio signal and an audio signal in multimedia, and the output request includes a request to establish an audio output channel.

[0037] There are many types of audio signals, the most common ones are ringtones, voice, music and calls, etc. These audio signals are independent audio signals, and there are also some audio signals in multimedia, for example, audio signals in videos. The user operates through the application interface, and if he wants to output the relevant audio signal through the corresponding audio output device, he needs to establish an audio output channel. That is, it is necessary to send a request to establish an audio output channel, and determine the final output terminal of the audio signal according to the output request of the audio signal. For example, in the case where the system only has a native audio output device, some common output requests for audio signals are: the sound in music and video is generally output from the speaker, and the sound of calls is generally output from the earpiece. If headphones are detected, the sound in music, video and call sounds are generally output from the headphones. It should be noted that the system mentioned in this embodiment and subsequent embodiments can be an intelligent device with a native audio output device or an intelligent device with both a native audio output device and a custom audio output device.

[0038] S120, determining whether there is a custom audio output device; wherein the custom audio output device is an audio output device other than the system native audio output device, and each of the custom audio output devices has a unique identifier, and the identifier is used to identify the corresponding custom audio output device.

[0039] Generally, the system is configured with relevant audio output devices, i.e., native audio output devices, when it leaves the factory or is sold, and is configured with commonly used audio routing rules by default. However, as the performance of the system gradually increases, the external devices that can be expanded are becoming more and more abundant, especially in some commercial services, which often expand more external audio output devices, i.e., custom audio output devices. For example, external audio output devices such as speakers and amplifiers. In this embodiment, whether the system has a custom audio output device will affect the audio signal routing method. Therefore, it is necessary to judge whether the system has a custom audio output device to determine the corresponding audio signal routing method. In this embodiment, each custom audio output device has a unique identifier, which is used to identify the custom audio output device corresponding to it.

[0040] S130: If the custom audio output device exists, establish an audio output channel for the audio output device specified by the output request of the audio signal; wherein the audio output device is selected from the custom audio output device and the native audio output device.

[0041] In this embodiment, when the system has a custom audio output device, such as the system has an external speaker, at this time, the audio output device of the entire system includes the system native audio output device and the custom audio output device, and then the audio output channel is established according to the audio signal output request of the specified audio output device, and the specified audio output device is derived from the custom audio output device or the native audio output device. For example, an Android device, the default supported common native audio output devices include the main speaker (different from the external speaker), the receiver, the earphone, etc., if the system adds three custom audio output devices A, B and C (external speakers). According to the above audio output configuration, when playing a section of audio, the user specifies the output to the external speaker A and the external speaker B and the system native main speaker through the API (Application Program Interface), then the audio signal is output to the external speaker A, the external speaker B and the main speaker according to this specification. Those skilled in the art should be able to understand that the user can have other specified methods according to actual needs, and no specific restrictions are made here.

[0042] In an optimized implementation, before receiving an output request for an audio signal, if the system has a custom audio output device, a unique identifier is added to each custom audio output device, and the identifier is used to identify the custom audio output device corresponding to the custom audio output device. Schematically, the identifier of the custom audio output device can be expressed in the form of a parameter. When the system has a custom audio output device, it adds a unique identifier to each custom audio output device, so that each custom audio output device is identifiable and unique, and can be applied to the user's audio signal output specification.

[0043] In a possible implementation, if the system does not have a custom audio output device, general audio routing is performed, wherein the general audio routing is to use the audio routing rules provided by the system for audio routing. That is, after judgment, in the absence of a custom audio output device, the system performs audio routing according to the default, general audio routing method.

[0044] A brief description of general audio routing is as follows: For an Android device, the default supported common audio output devices include speakers (main speakers), receivers, and headphones. 1. The sound in music and videos is usually output from the speakers. If the system detects that the system is connected to headphones, it is output from the headphones. 2. Calls are usually output from the receiver. If the system detects that the system is connected to headphones, it is output from the headphones. If the hands-free function is used, it is output from the speakers. 3. Incoming ringtones and alarms are output from the speakers. If the system detects that the system is connected to headphones, the speakers and headphones are output at the same time.

[0045] In a possible implementation, after the audio output channel is established, the audio signal is bound to an audio output device corresponding to the audio output channel, and the audio signal is output.

[0046] The audio routing method provided in this embodiment can use dynamic audio routing methods such as specified or general routing to find the corresponding audio output device and establish an audio output channel after any number of custom audio output devices are added to the system.

[0047] Embodiment 2

[0048] Figure 2 FIG. 1 is a flow chart of an audio routing method according to another embodiment of the present invention. Figure 2 , the method 200 comprises:

[0049] S110, receiving an output request for an audio signal, wherein the audio signal includes an independent audio signal and an audio signal in multimedia, and the output request includes a request to establish an audio output channel. The detailed description of this step has been described above and will not be repeated here.

[0050] S120, determining whether there is a custom audio output device; wherein the custom audio output device is an audio output device other than the system's native audio output device, and each custom audio output device has a unique identifier, and the identifier is used to identify the custom audio output device corresponding thereto. The detailed description of this step has been described before and will not be repeated here.

[0051] S210: If the custom audio output device exists and the output request of the audio signal does not specify an audio output device, general audio routing is performed; wherein the general audio routing is to perform audio routing using the audio routing rules provided by the system.

[0052] In this embodiment, although the system has a custom audio output device, the user has not specified a corresponding audio output device. At this time, the system performs general audio routing, that is, uses the system's own audio routing rules for audio routing.

[0053] In a possible implementation, the custom audio output device is used as a function extension of the main speaker. In this case, the native audio output device generally includes a main speaker, a receiver, and a headset, and the custom audio output device includes an external speaker.

[0054] After general audio routing is performed, determine whether the result of general audio routing includes the main speaker in the native audio output device. If the result of general audio routing includes the main speaker in the native audio output device, establish audio output channels according to the native audio output device and all custom audio output devices in the general audio routing result. For example, the system adds three custom audio output devices (external speakers) A, B, and C. When playing an audio (such as a ringtone), the user does not specify an audio output device. The system will use the default audio routing (general audio routing) method for audio routing and then check the audio routing result. If the audio routing result includes the main speaker, plus the custom audio output device that is an extension of the main speaker function, the final audio output result is the main speaker, external speaker A, external speaker B, and external speaker C. If the result of general audio routing does not include the main speaker in the native audio output device, establish audio output channels according to the native audio output device in the general audio routing result. For example, the system adds three custom audio output devices (external speakers) A, B, and C. When playing an audio clip (such as music played when headphones are connected), if the user does not specify an audio output device, the system will use the default audio routing (general audio routing) method for audio routing and then check the audio routing results. If the result of the general audio routing is headphones and does not include the main speaker, the system will directly establish an audio output channel for the headphones in the general audio routing result, and will not establish an audio output channel with the external speaker.

[0055] In a possible implementation, after the audio output channel is established, the audio signal is bound to an audio output device corresponding to the audio output channel, and the audio signal is output.

[0056] The audio routing method provided in this embodiment, when the system has a custom audio output device, still adopts a general audio routing method when no audio output device is specified, and finds the corresponding audio output device and establishes an audio output channel according to the association relationship between the main speaker and the custom audio output device.

[0057] Embodiment 3

[0058] Figure 3 FIG. 1 is a flow chart of an audio routing method according to another embodiment of the present invention. Figure 3 , the method 300 comprises:

[0059] S110, receiving an output request for an audio signal, wherein the audio signal includes an independent audio signal and an audio signal in multimedia, and the output request includes a request to establish an audio output channel. The detailed description of this step has been described above and will not be repeated here.

[0060] S310, determining whether there is a playing video; if there is no playing video, determining whether there is the custom audio output device.

[0061] As mentioned above, audio signals include independent audio signals and audio signals in multimedia, such as audio signals in videos. Although audio signals can exist independently, they can establish audio routing channels according to corresponding audio routing rules. However, in most cases, if there is video playback in the current system, the output audio signal is likely to be audio associated with the played video. Therefore, after receiving an output request for an audio signal, it can be determined whether there is a played video in the current system. If there is no played video, at this time, the audio signal is output as an independent output, and then it is determined whether there is a custom audio output device, and then the corresponding subsequent steps are performed.

[0062] In a possible implementation, if there is a video being played, it is determined whether the video being played is displayed on multiple screens with different displays. If the video being played is not displayed on multiple screens with different displays, it is determined whether there is a custom audio output device, and then the corresponding subsequent steps are performed. Multiple screens with different displays means that the video being played is not displayed on all display screens at the same time.

[0063] In one possible implementation, if the video is played on multiple screens, it is determined whether the output request of the audio signal specifies an audio output device. If the output request of the audio signal specifies an audio output device, it is determined whether there is a custom audio output device, and then the corresponding subsequent steps are performed.

[0064] In a possible implementation, if the audio signal output request does not specify an audio output device, the display screen that plays the video is identified, and the audio output device corresponding to the display screen that plays the video is used as the designated audio output device.

[0065] S120, determining whether there is a custom audio output device; wherein the custom audio output device is an audio output device other than the system's native audio output device, and each custom audio output device has a unique identifier, and the identifier is used to identify the custom audio output device corresponding thereto. The detailed description of this step has been described before and will not be repeated here.

[0066] S130: If the custom audio output device exists, establish an audio output channel for the audio output device specified by the output request of the audio signal; wherein the audio output device is selected from the custom audio output device and the native audio output device. The detailed description of this step has been described before and will not be repeated here.

[0067] In a possible implementation, after the audio output channel is established, the audio signal is bound to an audio output device corresponding to the audio output channel, and the audio signal is output.

[0068] The audio routing method provided in this embodiment determines whether there is a video currently being played in the system after receiving an output request for an audio signal, and performs corresponding processing based on whether there is a video being played, thereby more accurately meeting the output requirements of the audio signal.

[0075] 404. Determine whether the audio signal output request specifies an audio output device. If so, proceed to step 407; if not, proceed to step 405.

[0076] 405. Identify the display screen that plays the video.

[0077] 406. Designate the speaker (or other audio output device) corresponding to the display screen playing the video as the audio output device, and then proceed to step 407.

[0078] 407 . Determine whether the system has a custom audio output device. If so, proceed to step 408 . If not, proceed to step 413 .

[0079] 408. Determine whether the audio signal output request specifies an audio output device. If so, proceed to step 411; if not, proceed to step 409.

[0080] 409. Perform general audio routing, that is, use the audio routing rules provided by the system to perform audio routing.

[0081] 410. Determine whether the result of the general audio routing includes the main speaker in the native audio output device. If yes, proceed to step 412; if no, proceed to step 413.

[0082] 411. Use the specified audio output device to establish an audio output channel.

[0083] 412. Use the general audio routing result and the custom audio output device to establish an audio output channel.

[0084] 413. Use the general audio routing result to establish an audio output channel.

[0085] The audio routing method provided in this embodiment determines whether there is a video currently being played in the system, and performs corresponding processing according to whether there is a video being played, so as to more accurately meet the output requirements of the audio signal. And according to whether the system has a custom audio output device, dynamic audio routing methods such as specified or general routing are used to find the corresponding audio output device and establish an audio output channel.

[0086] Embodiment 5

[0087] Figure 5 FIG. 1 is a schematic diagram of the structure of an audio routing device according to an embodiment of the present invention. Figure 5 , the device 500 mainly includes:

[0090] The establishing module 503 is used to establish an audio output channel according to the audio output device specified by the output request of the audio signal if there is a custom audio output device, wherein the audio output device is selected from the custom audio output device and the native audio output device.

[0091] In a possible implementation, if there is no customized audio output device, general audio routing is performed, wherein the general audio routing is to perform audio routing using the audio routing rules provided by the system.

[0098] In a possible implementation, if the video is played on multiple screens, it is determined whether the output request of the audio signal specifies an audio output device. If the output request of the audio signal specifies an audio output device, it is determined whether there is a custom audio output device.

[0099] In a possible implementation, if the audio signal output request does not specify an audio output device, the display screen that plays the video is identified, and the audio output device corresponding to the display screen that plays the video is used as the designated audio output device.

[0100] The audio routing device provided in this embodiment can find the corresponding audio output device and establish an audio output channel by using dynamic audio routing methods such as designated or general routing after adding any number of custom audio output devices to the audio system. It can also directly use general audio routing when there is no custom audio output device.
