Specific embodiment
Specifically illustrate embodiments of the present invention with reference to the accompanying drawing, attached drawing is only for reference and illustrates use, does not constitute pair
The limitation of the invention patent protection scope.
On the one hand the embodiment of the present invention provides a kind of multi-region control method for playing back, comprising:
S10. the breakpoint information of media file is saved；
Specifically, comprising the following steps:
S101. the file type in proparea, back zone play area is obtained；
S102. it when detecting that corresponding breakpoint condition occurs, performs the next step；
Specifically, the corresponding breakpoint condition are as follows:
When proparea plays audio, the corresponding breakpoint condition are as follows: ACC invalidating signal, off signal are effective；Proparea plays
When video, the corresponding breakpoint condition are as follows: speed is greater than 0, ACC invalidating signal, and off signal is effective；
When the playing audio-video of back zone, the corresponding breakpoint condition are as follows: ACC invalidating signal, off signal are effective.
S103. corresponding breakpoint information is saved in corresponding breakpoint information storage zone.
Specifically, the breakpoint information includes media file name and current play time；The breakpoint information storage zone
For proparea breakpoint information storage zone and back zone breakpoint information storage zone.
When detecting that corresponding breakpoint condition occurs, proparea media file name and current play time are saved in proparea
Back zone media file name and current play time are saved in back zone breakpoint information storage zone by breakpoint information storage zone.
S20. car status information is obtained；
Specifically, the car status information includes driving states and parked state.
In the specific implementation, it can determine that vehicle is in driving by obtaining gear information and the parking brake information of vehicle
State or parked state perhaps read vehicle speed information by automotive networking (such as CAN, LIN) to determine or pass through
The velocity information of locating module (such as GPS, Beidou) determines.
S30. playback of media files area information is obtained；
Specifically, the play area information includes proparea broadcast information and back zone broadcast information.
S40. breakpoint information is read according to the car status information, playback of media files area information；
Specifically, when the car status information is driving states, and the currently playing media in proparea are video file,
Back zone breakpoint information is read, proparea and back zone breakpoint information are otherwise read.
According to traffic relevant regulations, in driving states, driver (proparea) does not allow to watch video class broadcast source, because
This shields proparea breakpoint when the car status information is driving states, and the currently playing media in proparea are video file
Information only reads back zone breakpoint information；And when the car status information is parked state, permission proparea is watched video class and is played
Source, it is therefore desirable to read proparea breakpoint information.
S50. decoding compatible information is obtained according to the playback of media files area information；
Specifically, the decoding compatible information includes mutual exclusion and compatible.
Onboard system can play multimedia source, such as the source DVD, the source USB, the source SD there are multiple；It is also typically present at least
One decoder module, when only one decoder module, these can play multimedia source and then share a decoder module, that is, say
When bright current back zone will play multimedia, then the same decoder module can only be used, that is, there is mutual exclusion；Some onboard systems are then
There are two or more decoder modules, such as the source DVD, and DVD decoder module is used alone, and USB, SD are used alone another
Decoder module, then it is preceding in other situations only when proparea plays USB, back zone plays SD, or conversely, can just there is mutual exclusion
The source that back zone can respectively be selected with independent play-out, i.e., it is compatible.
S60. according to the breakpoint information and decoding compatible information selection decoder module and media channel；
Specifically, when the breakpoint information be back zone breakpoint information when, then according to back zone broadcast source select decoder module and
Media channel；
When the breakpoint information is proparea and back zone breakpoint information, if the decoding compatible information is mutual exclusion, root
Decoder module and media channel are selected according to proparea broadcast source；If the decoding compatible information be it is compatible, played according to proparea
Source, back zone broadcast source select decoder module and media channel respectively.
S70. the breakpoint information of selection is received, and plays media decoding from breakpoint according to breakpoint information control
File.
