Description

Technical Field

[0001] The present invention belongs to the technical field of audio and video processing, and in particular relates to a method and a device for custom switching of in-vehicle audio modes. Background Art

[0002] With the development of in-vehicle audio and video technology, there are more and more functions such as multi-screen interaction of audio and video, audio and video playback between multiple screens, and voice navigation. The audio focus switching method is basically adopted in the speaker processing in the car. For example, when the sound of the navigation software appears, the focus is switched to the navigation, and the volume of the background music is lowered at the same time. After the navigation sound is finished, the audio focus is switched to the music playback.

[0003] However, such frequent focus switching will lead to a worse in-car audio experience, with the following problems: (1) In various audio scenarios, such as navigation, music, karaoke, and watching videos, switching the audio focus back and forth will greatly affect the in-car experience; (2) When some drivers need navigation and other people in the car need to rest, it will affect the rest of other people in the car; (3) It is impossible to dynamically set the playback area and playback strategy for different audio sources or audio types. Most of them have a unified output or use focus switching, which cannot achieve the audio playback strategy desired by people in the car. Summary of the invention

[0004] In view of the above problems, the present invention provides a method and device for customizing switching of in-car audio modes, which are used to perform customizable configuration and switching of different sound zones and different audios in the car, so as to achieve the audio playback strategy desired by the occupants of the car.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] In one aspect, the present invention provides a method for customizing in-vehicle audio mode switching, comprising the following steps:

[0007] Configure the audio mode, including setting the output mode of different audio sources, setting the output position of different audio sources, and setting the priority for focus grabbing strategy;

[0008] When different audio sources arrive, the audio sources are parsed and information is obtained, including the format, type, and USAGE information of the audio sources;

[0009] Issue an audio partition request, and configure it into multiple playback partitions according to the audio mode. When a playback partition is bound to multiple types of audio sources, set the focus preemption strategy according to the priority.

[0010] Mark different audio sources and create different decoders for decoding;

[0011] After decoding is completed, the decoded data is sent to the corresponding playback partition for playback according to different strategies.

[0012] In a possible implementation, the playback zones include a driver's seat playback zone, a rear seat playback zone, a passenger seat playback zone, a headrest audio playback zone, and a Bluetooth playback zone.

[0013] In a possible implementation, each playback partition receives a different audio source, different audio sources are set with different playback priorities, and a focus preemption strategy is performed according to the priority.

[0014] In a possible implementation, the playback partitions are dynamically bound according to playback requirements.

[0015] In one possible implementation, the playback partitions are dynamically bound according to playback requirements, including: each audio partition corresponds to a playback configuration file, each playback partition has a corresponding physical audio output device, and the corresponding parameters of the audio source, the playback partition, and the physical audio output device are corresponded and bound in the playback configuration file. After the binding is completed, the corresponding audio source is sent to the corresponding audio partition for playback.

[0016] Another aspect of the present invention provides a device for customized switching of in-vehicle audio modes, comprising an audio parsing module, an audio mode configuration module, an audio mode control module, an audio decoding module and an audio partitioning module.

[0019] The audio mode control module is used to process the audio of the audio and video source according to the current audio mode, send it to the audio decoding module for decoding, and control the audio partition module to play the partition according to the current audio mode;

[0020] The audio partition module is used to divide the audio into multiple playback partitions according to the configuration. When a playback partition is bound to multiple types of audio sources, the focus grabbing strategy is set according to the priority.

[0021] The audio decoding module is used to mark different audio sources and create different decoders for decoding; after decoding, the decoded data is sent to the corresponding playback partition for playback according to different strategies.

[0022] In a possible implementation, the playback zones include a driver's seat playback zone, a rear seat playback zone, a passenger seat playback zone, a headrest audio playback zone, and a Bluetooth playback zone.

[0023] In a possible implementation, each playback partition receives a different audio source, different audio sources are set with different playback priorities, and a focus preemption strategy is performed according to the priority.

[0024] In a possible implementation, the playback partitions are dynamically bound according to playback requirements.

[0025] In one possible implementation, the playback partitions are dynamically bound according to playback requirements, including: each audio partition corresponds to a playback configuration file, each playback partition has a corresponding physical audio output device, and the corresponding parameters of the audio source, the playback partition, and the physical audio output device are corresponded and bound in the playback configuration file.

[0030] Figure 2 The present invention is a block diagram of a device for customized switching of in-vehicle audio modes according to an embodiment of the present invention. DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 , which is a flowchart of a method for customizing in-vehicle audio mode switching according to an embodiment of the present invention, includes the following steps:

[0033] S10, configuring the audio mode, including setting the output mode of different audio sources, setting the output position of different audio sources and setting the priority to perform the focus grabbing strategy;

[0034] S20, when different audio sources arrive, the audio sources are parsed and information is obtained, the information including the format, type, and USAGE information of the audio sources;

[0035] S30, issuing an audio partition request, configuring and dividing into multiple playback partitions according to the audio mode, and when a playback partition is bound to multiple types of audio sources, setting a focus grabbing strategy according to the priority;

[0036] S40, marking different audio sources and creating different decoders for decoding;

[0037] S50, after decoding is completed, the decoded data is sent to the corresponding playback partition for playback according to different strategies.

[0038] In one embodiment of the present invention, in S10, the configuration of the audio mode can use several default audio modes, such as: driving mode, karaoke mode, phone mode, Bluetooth mode, etc., or a custom mode can be set. Different output positions of different audio sources can be set, such as setting the audio source of navigation information to output to the driver's seat, the audio source of incoming calls to output to Bluetooth headphones, the audio source of karaoke to output to rear speakers, etc. Different audio sources can also be set to output to the same output position, and priorities can be set to perform focus grabbing strategies, etc.

[0039] In one embodiment of the present invention, in S20, when several different audio sources arrive, they are first parsed to parse out information of different audio sources. For example, for the audio source of navigation, USAGE is identified as navigation sound, for the audio source of telephone, USAGE is identified as telephone, for the playback of iQiyi, USAGE from iQiyi is identified as the audio source of the movie, and for the playback of music, USAGE is identified as music mode.

[0040] In one embodiment of the present invention, in S30, the playback partitions include a driver's seat playback partition, a rear seat playback partition, a co-pilot playback partition, a headrest audio playback partition, and a Bluetooth playback partition. Each playback partition receives different audio sources, and different audio sources are set with different playback priorities, and a focus grabbing strategy is performed according to the priority. The focus grabbing strategy is a strategy when an audio output device plays more than two types of audio sources. If two different sources are directly mixed and output, the sound will be too messy. If there is an audio focus, the audio focus will be grabbed according to the priority. The audio source that grabs the audio focus will play normally, and the audio source that does not grab the focus will reduce the sound, pause or mute; after the audio source that grabs the audio focus finishes playing and releases the focus, the audio source that does not grab the focus will resume normal playback.

[0041] In one embodiment of the present invention, in S30, the playback partitions can be dynamically bound according to the playback requirements, specifically including: each audio partition corresponds to a playback configuration file, each playback partition has a corresponding physical audio output device, and the corresponding parameters of the audio source, the playback partition, and the physical audio output device are corresponded and bound in the playback configuration file. After the binding is completed, the corresponding audio source is sent to the corresponding audio partition for playback.

[0042] In S40 of a specific application example, different audio sources are marked and different decoders are created for decoding. For example, if the audio format is AAC, an AAC decoder is created for decoding. If it is Dolby Atmos, a Dolby Atmos decoder is created for decoding.

[0043] In S50 of a specific application example, after decoding is completed, according to different strategies, the decoded data of navigation and phone calls can be sent to the headrest speaker playback partition, the audio source of iQiyi playback can be sent to the co-pilot playback partition, and the decoded audio data of music playback can be sent to the Bluetooth headset for playback. At this time, the driver of the main car can hear the navigation sound through the headrest speaker. If a call comes in at this time, the phone will seize the focus of the headrest speaker and give priority to playing the phone sound. The speaker of the co-pilot part will play the iQiyi video. The passengers sitting in the back row can wear headphones to enjoy the music. The three people do not interfere with each other.

[0044] Through the above-set in-car audio mode custom switching method, different areas in the car can be divided into different playback zones, and different audio and video sources can be bound to different playback zones through custom configurations, achieving a flexible, dynamic, and adjustable audio and video experience. It can minimize the interference between different audio sources in the car and achieve the best smart cockpit audio experience that passengers want.

[0045] For method embodiments, see Figure 2 Another embodiment of the present invention provides a device for custom switching of in-vehicle audio modes, including an audio parsing module, an audio mode configuration module, an audio mode control module, an audio decoding module and an audio partition module, wherein the audio mode configuration module is used to configure the audio mode, including setting the output mode of different audio sources, setting the output position of different audio sources and setting the priority for focus grabbing strategy; the audio parsing module receives different audio sources, parses the audio sources and obtains information, wherein the information includes the format, type and usage information of the audio sources; the audio mode control module is used to process the audio of the audio and video sources according to the current audio mode, send it to the audio decoding module for decoding, and control the audio partition module to play the partition according to the current audio mode; the audio partition module is used to divide into multiple playback partitions according to the configuration, and when a certain playback partition is bound to multiple types of audio sources, the focus grabbing strategy is set according to the priority; the audio decoding module is used to mark different audio sources and create different decoders for decoding; after decoding, according to different strategies, the decoded data is sent to the corresponding playback partition for playback.

[0046] In one embodiment of the present invention, in the audio mode configuration module, the configuration of the audio mode can use several default audio modes, such as: driving mode, karaoke mode, phone mode, Bluetooth mode, etc., or a custom mode can be set. Different output positions of different audio sources can be set, such as setting the audio source of navigation information to output to the driver's seat, outputting the audio source of incoming calls to Bluetooth headphones, outputting the audio source of karaoke to the rear speakers, etc. Different audio sources can also be set to output to the same output position, and priorities can be set to perform focus grabbing strategies, etc.

[0047] In one embodiment of the present invention, in the audio decoding module, when several different audio sources arrive, they are first parsed to parse out information of different audio sources. For example, the audio source of navigation recognizes that USAGE is navigation sound, the audio source of telephone recognizes that USAGE is telephone, the playback of iQiyi recognizes that USAGE from iQiyi is the audio source of the movie, and the music playback recognizes that USAGE is music mode.

[0048] In one embodiment of the present invention, in the audio partition module, the playback partitions include a driver's seat playback partition, a rear seat playback partition, a co-pilot playback partition, a headrest audio playback partition, and a Bluetooth playback partition. Each playback partition receives different audio sources, and different audio sources are set with different playback priorities, and a focus preemption strategy is performed according to the priority. The focus preemption strategy is a strategy when an audio output device plays more than two types of audio sources. If two different sources are directly mixed and output, the sound will be too messy. If there is audio focus, the audio focus will be grabbed according to the priority. The audio source that grabs the audio focus will play normally, and the audio source that does not grab the focus will reduce the sound, pause or mute; after the audio source that grabs the audio focus finishes playing and releases the focus, the audio source that does not grab the focus will resume normal playback.

[0049] In one embodiment of the present invention, in an audio partition module, playback partitions can be dynamically bound according to playback requirements, specifically including: each audio partition corresponds to a playback configuration file, each playback partition has a corresponding physical audio output device, and the corresponding parameters of the audio source, the playback partition, and the physical audio output device are corresponded and bound in the playback configuration file. After the binding is completed, the corresponding audio source is sent to the corresponding audio partition for playback.

[0050] In an audio decoding module of a specific application example, different audio sources are marked and different decoders are created for decoding. For example, if the audio format is AAC, an AAC decoder is created for decoding. If it is Dolby Atmos, a Dolby Atmos decoder is created for decoding.

[0051] In the audio decoding module of a specific application example, after decoding is completed, according to different strategies, the decoded data of navigation and phone calls can be sent to the headrest speaker playback partition, the audio source played by iQiyi can be sent to the co-pilot playback partition, and the decoded audio data of music can be sent to the Bluetooth headset for playback. At this time, the driver can hear the navigation sound through the headrest speaker. If a call comes in at this time, the phone will seize the focus of the headrest speaker and give priority to the playback of the phone sound. The speaker of the co-pilot part will play the iQiyi video. The passengers sitting in the back row can wear headphones to enjoy the music. The three people do not interfere with each other.

[0052] Through the above-set in-car audio mode custom switching device, different areas in the car can be divided into different playback zones, and different audio and video sources can be bound to different playback zones through custom configurations, achieving a flexible, dynamic, and adjustable audio and video experience. It can minimize the interference between different audio sources in the car and achieve the best smart cockpit audio experience that passengers want.
