Abstract
The invention provides a voice frequency changing-over management system in a vehicle-mounted entertainment system and a control method thereof. The voice frequency changing-over management system in the vehicle-mounted entertainment system and the control method thereof are composed of voice frequency changing-over management and sound source changing-over management. The voice frequency changing-over management comprises a voice frequency system, the voice frequency system is composed of policy table management, single/multiple voice frequency information management, a changing-over access, an action policy and a volume policy. The changing-over access is connected with a micro control unit (MCU) interface, the voice frequency system is connected with an android media voice frequency system, and the android media voice frequency system is connected with a voice frequency manager. According to the voice frequency changing-over management system in the vehicle-mounted entertainment system and the control method thereof, an external channel is arranged, and the voice frequency changing-over management system in the vehicle-mounted entertainment system and the control method thereof can be applied in various intelligent devices under android and provides a good solution to voice frequency processing with extended functions in the intelligent devices.
Description
Technical field
The present invention relates to a kind of vehicle entertainment system sound intermediate frequency handover management system and control method thereof.
Background technology
Audio conversion management traditional under Android system is mainly for the common audio kind in mobile phone, and such as: carry out electric bell sound, remove electric sound, mp3 sound, tts sound, system starts sound etc.All for inside digital audio are divided into above a few class and carry out control and management broadcasting by system.The defect of Audio conversion way to manage traditional under android system:
1, more types of audio cannot be expanded.Further expand the function of system.
2, when multiple systems audio frequency is play simultaneously, the stratified voice output that volume is different cannot be realized.
3, by the uncontrollable analog input source of sound of Android system, such as: we increase radio module newly, the source of sound of radio reception is exported and cannot be controlled by Android system.
Summary of the invention
Technical problem to be solved by this invention is, be applied in the vehicle entertainment system based on Android system, in current vehicle entertainment system, to entertainment orientation, integrated, intelligent and multifunction strides forward, and these determine the current requirement to vehicle-mounted computer and improve further, require that we provide a kind of solution of novelty to realize these functional requirements, we have proposed the Audio conversion Managed Solution based on the Big Dipper under a kind of Android like this.
A kind of vehicle entertainment system sound intermediate frequency handover management system, be made up of Audio conversion management and source of sound handover management, described Audio conversion management comprises audio system, described audio system is made up of Policy Table's management, the information management of list/Multi-audio-frequency, switched path, action policy and volume strategy, described switched path is connected with MCU interface, described audio system is connected with Android media audio system, and described Android media audio system is connected with audio manager.
Preferably, in source of sound handover management, source of sound comprises: Ringtone bell sound, Media voice, navigation speech, FMAM voice, 3G call, system push sound, TTS voice, carry out electric bell sound.
Preferably, described Ringtone bell sound comprises system alert/error tone. note sound, calendar prompt tone, conventional system prompt tone.
Present invention also offers a kind of control method of vehicle entertainment system sound intermediate frequency handover management system, comprise following step:
Steps A: start this application after registered application software;
Step B: carry out after adding the audio-frequency information that will play playing, Multi-audio-frequency strategy processing center by resolving instruction, carry out Audio conversion or volume controls;
Step C: play after the process of treated audio frequency policy message readjustment.
Under android, realize Audio conversion management, do not changing primary AudioManager, on the basis of AudioService interface, the inner realization of amendment changes audio frequency broadcast state, and corresponding process is made in the corresponding application of notice.Here apply as client, an AudioManager(audio frequency controller) manage the application of registration as a service, so application must first be registered in AudioManager be just subject to audio frequency policy control
Simultaneously due to AudioSwitch audio-switch, only support that the sound of a passage plays back, so we provide the function of passage bridge according to the type play.
The present invention is that a kind of management based on audio-source multiple under Android system controls, and realizes the digital audio source of internal system and the Audio conversion management of external analog audio source by Android system and peripheral control circuits.Control based on the handover management of Beidou navigation sound with other various sources of sound.Current Android system has been applied in various mobile device terminal, such as mobile phone, panel computer, the various equipment such as vehicle-mounted, but the handover management of Android system at audio frequency and the handover management of other various analogue audio frequencies, cannot utilize the existing Audio conversion of android to manage the effect and function realized required by us.Such as: muli-sounds is play, arrange that the volume value of often kind of source of sound is different to be broadcasted simultaneously simultaneously, obviously can recognize the sound of the various sense that has levels; The source of sound (wireless volume exports, the output of 3G simulated sound) that external analog exports does handover management by Android system and regulates volume etc. associative operation.
The present invention adds external channel, and can be applied in the various smart machines under android, the audio frequency process for expanded function in smart machine provides good solution.This invention is not tightly limit and current several audio types, can adopt similar processing mode to any additional audio types.
Accompanying drawing explanation
Fig. 1 is the principle schematic of an embodiment of the present invention;
Fig. 2 is the principle schematic of an embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, preferably embodiment of the present invention is described in further detail:
As shown in Figure 1, a kind of vehicle entertainment system sound intermediate frequency handover management system, be made up of Audio conversion management and source of sound handover management, described Audio conversion management comprises audio system, described audio system is made up of Policy Table's management, the information management of list/Multi-audio-frequency, switched path, action policy and volume strategy, described switched path is connected with MCU interface, and described audio system is connected with Android media audio system, and described Android media audio system is connected with audio manager.
As shown in Figure 2, a kind of control method of vehicle entertainment system sound intermediate frequency handover management system, comprises following step:
Steps A: start this application after registered application software;
Step B: carry out after adding the audio-frequency information that will play playing, Multi-audio-frequency strategy processing center by resolving instruction, carry out Audio conversion or volume controls;
Step C: play after the process of treated audio frequency policy message readjustment.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection of the present invention.
