Problems solved by technology

[0003] With the gradual enhancement of the functions of the vehicle infotainment system, its equipment is becoming more and more complex, and most of the entertainment applications in the system need to play sound. The technology does not deal with the situation of multiple audio sources appearing at the same time, and the system is prone to multiple audio sources seizing control of sound playback, resulting in confusing playback sounds

Embodiment 1

[0035] When the priority of the currently output sound is higher than that of the requested sound, continue to play the currently output sound.

[0036] For example, the currently output sound is a system sound, and the type of sound requested to be played is voice and media sound. At this time, it can be compared that the priority of the currently output sound is higher than that of the sound requested to be played. At this time Just keep playing the current system class sound.

[0037] In special cases, when the currently output sound is telephone, if the sound requested to be played at this time is navigation or system type, although the current output sound continues to be played, a special prompt sound needs to be output at the same time.

[0038] When the priority of the currently output sound is lower than the priority of the requested sound, interrupt the currently output sound, process the sound play request information, and restore the interrupted currently output so...

Embodiment 2

[0044] The difference from the above situation is that if the currently output sound is the sound output of the system class, if the sound that is requested to be played at this time is the phone class, switch to the phone channel and mute the system class sound without stopping the system class sound. However, if the sound requested to be played at this time is system type, if the time interval of the request is less than 5s, then the system type sound is discarded, and if the request time interval is greater than 5s, the system type sound is queued for waiting.

Embodiment 4

[0046] When the priority of the currently output sound is equal to the priority of the sound requested to be played, it needs to be divided into the following situations:

[0047] 1) The currently output sound and the requested sound are both system sounds.

[0048]The system sound itself can also distinguish the playback level. If the currently output sound and the sound requested to be played are both system sounds, it is necessary to judge the level of the currently output sound and the sound requested to be played. If the level of the currently output system sound is low At the level of the requested system sound, interrupt the currently output system sound, process the requested system sound, and resume the interrupted currently output system sound after completing the requested sound.

[0049] If the level of the currently output system sound is equal to the level of the system sound requested to be played, continue the current output system sound and queue the system so...

Abstract

The invention provides a sound conflict processing method based on a vehicle-mounted information entertainment system. The sound conflict processing method includes that sound playing request information is received; whether sound output exists at present is judged; if on yes judgment, sound priority of current output sound is compared with that of sound required to be played according to predefined sound, and comparing results are generated; and sound conflict processing is performed according to the comparing results. Sound classification is used for performing playing control, sound in the vehicle-mounted information entertainment system is classified, sound with low priority is interrupted by sound with high priority, the system can recover the interrupted sound automatically after the sound with high priority is output, and usability of the system is increased.

Description

technical field [0001] The present invention relates to vehicle-mounted information processing technology, in particular to a sound conflict processing method based on a vehicle-mounted infotainment system. Background technique [0002] With the continuous improvement of automobile comfort and entertainment requirements, many mature technologies such as network, communication, and audio-visual entertainment in daily life (such as MP3 / MP4 players, GPS navigation, radios, video players, car phones, etc.) Transplanted into the vehicle infotainment system, its audio-visual playback function and information processing function are increasingly enhanced. [0003] With the gradual enhancement of the functions of the vehicle infotainment system, its equipment is becoming more and more complex, and most of the entertainment applications in the system need to play sound. The technology does not deal with the situation where multiple audio sources appear at the same time, and the syst...
