Description in, be described in detail taking a smart TV as an example, but do not represent that the present invention is limited to smart televisions.
Fig. 3 shows a kind of switching audiovisual applications flow diagram provided in an embodiment of the present invention.Refering to what is shown in Fig. 3,
The process of the switching audiovisual applications includes:
Step 100: receiving the instruction for switching to target audiovisual applications.
Specifically, smart television receives the control instruction of user's transmission, which, which exits, works as
Preceding audiovisual applications, and it is switched to target audiovisual applications.It is exemplary, if the smart television has touch-control control technology, use
Family can input the switching command by the touch panel of the smart television；If the smart television has voice control technology,
User can input the switching command by the speech control module of the smart television；No matter whether the smart television has touch-control
Control technology and voice control technology, user can send the switching command by remote controler.It is exemplary, it below will be with user
The implementation procedure of step 100 is described in detail for sending the switching command to smart television by remote controler.
It is exemplary, the implementation procedure of step 100 specifically: smart television receives the remote controler key assignments of user's transmission, into
And smart television obtains the corresponding target audiovisual applications of the remote controler key assignments.Specifically, smart television is receiving user's hair
After the remote controler key assignments sent, the corresponding relationship list of its remote controler key assignments configured and application identities is searched, the remote control is obtained
The application identities of target application corresponding to device key assignments, exemplary, which is the Apply Names of the target application.Example
, the corresponding relationship of remote controler key assignments and application identities is listed as follows shown in table table one.
| Remote controler key assignments | Corresponding Apply Names |
| KeyEvent 1 | Audiovisual applications A |
| KeyEvent 2 | Audiovisual applications B |
| KeyEvent 3 | Audiovisual applications C |
| KeyEvent 4 | Using D |
It is exemplary, during smart television playing audio-video application A, receive user sent by remote controler it is distant
Device key value Key Event3 is controlled, after receiving the key assignments, smart television inquires remote controler key assignments and the corresponding relationship of application identities arranges
Table table one, obtaining the corresponding target audiovisual applications of the remote controler key assignments is audiovisual applications C, i.e. smart television receives switching
To the instruction of target audiovisual applications C, then enters step 110 and executed.
Step 110: starting preset intermediate interface, and set backstage journey for the audiovisual applications being being currently used
Sequence.
Specifically, in the implementation procedure of step 110, start preset intermediate interface, while will be being currently used
Audiovisual applications are set as background program.Exemplary, which is being currently used audiovisual applications A, for example, currently just
It has received when receiving remote controler key assignments KeyEvent3 using iqiyi.com video and switches to target audiovisual applications
The instruction of C, for example, target audiovisual applications C is Tencent's video, at this point, the intermediate interface that starting is preset, and by iqiyi.com video
It is set as background program.
It should be noted that intermediate interface is preset lightweight interface, does not include sound audio and video playing content, therefore use
Audio/video decoder；And the interface content of intermediate interface is fewer than the interface content of target audiovisual applications, therefore intermediate interface
Start-up loading speed is faster than the start-up loading speed of target audiovisual applications.Exemplary, intermediate interface only includes a layout control
Part and a small amount of interface content, to realize the quick load of intermediate interface.Preferably, intermediate interface does not include in any interface
Hold, an only layout control, i.e. intermediate interface are a blank interface, further increase the loading velocity of intermediate interface.
When entering foreground after intermediate interface start completion, the interface for triggering the audiovisual applications A being being currently used is temporary
Stop, and then audiovisual applications A exits into background program, it should be noted that in Android operation system, current sound view
Frequency exits foreground using the interface of A and enters backstage, and an interface start completion is needed to enter foreground triggering.
Step 120: the intermediate interface loaded, triggering are set to described in the audiovisual applications release of background program
Audio/video decoder, and start the broadcast interface of the target audiovisual applications.
Specifically, after currently used audiovisual applications A enters backstage, discharging audio-video in Android operation system
The process of decoder needs the interface load that one enters foreground and completes to trigger.When the intermediate interface for entering foreground loads
When completion, the audiovisual applications A that triggering enters backstage stops using its corresponding player, and then audiovisual applications A starts to release
Playback Video Decoder.
It is exemplary, it is in step 110, intermediate by taking audiovisual applications A is third party's audiovisual applications iqiyi.com video as an example
After interface launches into foreground, the iqiyi.com video being being currently used exits foreground and enters backstage, when the centre for entering foreground
When interface load is completed, the iqiyi.com video that triggering is located at backstage stops using its corresponding iqiyi.com video player, and love is odd
After skill video player is stopped using, start to discharge the audio/video decoder that iqiyi.com video occupies.
Due to after currently used audiovisual applications enter backstage, discharging audio/video decoding in Android operation system
The process of device needs the interface load that one enters foreground and completes to trigger, and the intermediate interface of the embodiment of the present invention is one
A lightweight interface, interface content is less than the interface content of target audiovisual applications, therefore the loading velocity of intermediate interface is fast
Loading velocity in target audiovisual applications interface, therefore, the intermediate interface of the embodiment of the present invention may be implemented after entering foreground
Quickly load, and then the audiovisual applications release audio/video decoder being being currently used is triggered, unlocking noise can be triggered in advance
Video Decoder, and then shorten the waiting time of triggering audio/video decoder release.
Intermediate interface into foreground, which loads, to be completed, and the audiovisual applications A that triggering enters backstage starts to discharge its occupancy
While audio/video decoder, the broadcast interface starting of triggering target audiovisual applications B.Broadcasting circle of target audiovisual applications B
After face launches into foreground, triggering intermediate interface exits foreground and enters backstage, while target audiovisual applications B starts to load its boundary
Face content.
What needs to be explained here is that starting audiovisual applications B's first broadcasts after the completion of the intermediate interface into foreground loads
Interface is put, rather than directlys adopt audiovisual applications B and plays corresponding audio and video resources, because of audiovisual applications B and audio-video
An audio/video decoder may be shared using A, when setting currently playing interface for the broadcast interface of audiovisual applications B,
The audiovisual applications A for being switched to running background might not release its decoder resources occupied, so executing the step
After 120, need to judge whether the state of audio/video decoder is to enter if the state of audio/video decoder is the free time free time
Step 130.
By taking the smart television of Android operation system as an example, a decoder is only provided in Android operation system, certainly,
It is also general in other operating systems that a decoder, such as IOS operating system are only set, even if there are two solutions in some settings
In the operating system of code device, it is also possible to the case where two audiovisual applications share a decoder resources occur, so this hair
There is a decoder or two decoders or multiple decoders without limitation to terminal device in bright embodiment.
To avoid audiovisual applications A and audiovisual applications B from sharing the same audio/video decoder, the embodiment of the present invention is being opened
After the broadcast interface of moving-target audiovisual applications B, the state of audio/video decoder is inquired, as shown in figure 4, specifically looking into
Asking step can be with are as follows:
Step 201: calling the corresponding interface of audio/video decoder, whether the interface has code stream in detection preset time threshold
Output；
Step 202: if the interface is exported without code stream, judging the state of audio/video decoder for the free time.
Smart television can call the corresponding interface of its audio/video decoder, by detecting the interface in preset time threshold
Inside whether there is code stream output, finished to judge whether the audio/video decoder discharges, i.e., by whether judging audio/video decoder
There is audio, video data output, determines whether audiovisual applications A releases its occupied audio/video decoder.Specifically, if
The interface of audio/video decoder exports in preset time threshold without audio, video data, then illustrates that audiovisual applications A has been released
Its occupied audio/video decoder is put, i.e. the state of audio/video decoder is the free time；If it is determined that arriving audio/video decoder
Interface have audio, video data output in preset time threshold, then illustrate that audiovisual applications A does not discharge occupied by it completely
Audio/video decoder, i.e. the state of audio/video decoder is busy.
Specifically during executing step 201, if detecting the interface of audio/video decoder in preset time threshold
Inside there is audio, video data output, then according to default polling cycle, circulation executes step 201, i.e., recycles according to preset period of time
Whether the interface of detection audio/video decoder has audio, video data output in preset time threshold, until detecting preset time
The corresponding interface of audio/video decoder is exported without code stream in threshold value, enters step 202 execution.
Exemplary, default polling cycle can be set to 250ms, certainly, in order to play target audiovisual applications B as early as possible,
Default polling cycle can be arranged it is shorter, such as 200ms.
It should be noted that default polling cycle can also set the variable cycle when specific implementation, such as the first time with
250ms is that preset period of time is inquired, and is inquired for the second time by preset period of time of 200ms, for the third time with 150ms
Inquire for preset period of time etc., in this way, the state of decoder can be quickly obtained, once the state of decoder becomes
For the free time, target audiovisual applications can be played faster.
It should be noted that preset time threshold can be any time length, exemplary, preset time threshold be can be
0.01ms is also possible to 0.1ms, can also be 100ms, and the embodiment of the present invention does not do the specific size of preset time threshold
It limits.
In the case where the state of decoder is idle, step 130 is executed: if the state of audio/video decoder is sky
Spare time then indicates that target audiovisual applications send play instruction to the audio/video decoder.
As can be seen from the above-described embodiment, it after smart television receives the instruction for switching to target audiovisual applications, opens
Move preset intermediate interface, intermediate interface, which enters behind foreground, to be triggered the audiovisual applications being being currently used and enter backstage, in turn
After the completion of intermediate interface load, the audiovisual applications that triggering enters backstage discharge the audio/video decoder of its occupancy, and start mesh
The broadcast interface of mark with phonetic symbols Video Applications, after audio/video decoder release, target audiovisual applications are to audio/video decoder
Play instruction is sent, the handoff procedure of the audiovisual applications terminates, therefore the audiovisual applications switching time of the embodiment of the present invention is
The sum of start-up loading time and the release time of audio/video decoder of intermediate interface, and audiovisual applications in the prior art
Switching time is the sum of interface start-up loading time and release time of audio/video decoder of target audiovisual applications, due in
Between interface interface content it is fewer than the interface content of target audiovisual applications, therefore, the start-up loading time of intermediate interface compares mesh
The start-up loading time of mark with phonetic symbols Video Applications is short, so the audio-video switching method of the embodiment of the present invention shortens audiovisual applications
Between switching time, shorten the waiting time of target audiovisual applications, improve the user experience of smart television.
Further, prior to step 110, which receives switch to the instruction of target audiovisual applications after,
Application switching animation is presented in the display screen of the smart television, since the window level of animation play window is higher than audiovisual applications
Window level, the interfaces windows of audiovisual applications are in invisible mode, therefore, the intermediate interface started in the step 120
It will not be seen by the user during entire changing interface, improve the user's body of the switching audiovisual applications of the embodiment of the present invention
The property tested.
Exemplary, which can be the animation file being preset in the smart television, or use
The screenshot of preset picture or application program, the file of the animation effects such as addition amplification, sliding, diffusion.
For preferably describe the embodiment of the present invention switching audiovisual applications method, below in conjunction with specific example into
Row detailed description.
By taking the smart television with Android operation system as an example, iqiyi.com video X is used in the current smart television
It plays " rural love ", and user wants that the smart television is switched to live telecast Y plays " world football ", when the smart television
It receives after switching to the instruction of live telecast Y, specific switching flow is as shown in Figure 5.
Refering to what is shown in Fig. 5, after the smart television receives the instruction for switching to live telecast Y of user's transmission, switching
The preset intermediate interface E of controller Z-direction sends enabling signal, at the same switch controller Z control the smart television play it is preset
Switch animation file, the broadcast window level of the switching animation file is higher than the broadcast window level and live streaming of iqiyi.com video X
The broadcast window level of TV Y, therefore, in entire handoff procedure, the display screen of the smart television shows switching animation text
The broadcast interface of part.
Further, after the preset intermediate interface E receives the enabling signal of switch controller transmission, if in this
Between interface E be to start for the first time, then intermediate interface E enters onCreate life cycle (creation period), subsequently into
OnStart life cycle (starting period)；If intermediate interface E is not to start for the first time, intermediate interface E is directly entered
OnStart life cycle (starting period).
Exemplary, intermediate interface E is a blank interface, only includes a layout control, does not add specific interface
Content, therefore, the onCreate life cycle and onStart life cycle duration of intermediate interface E are very short, among this
Interface E can enter foreground by quick pull-up.
Further, while intermediate interface E enters onStart life cycle, trigger iqiyi.com video X interface into
Enter onPause life cycle (pause period), and then foreground is exited at the interface of iqiyi.com video X, into backstage.Work as intermediate interface
After the onStart life cycle of E, enter onResume life cycle (service life) after the completion of intermediate interface E load, when
When intermediate interface E enters onResume life cycle, the interface that triggering enters the iqiyi.com video X on backstage enters onStop life
Period (dwelling period).After the interface of iqiyi.com video X enters onStop life cycle, and then stop broadcast corresponding with its is discharged
Device is put, the occupied audio/video decoder R of iqiyi.com video is then discharged.When intermediate interface E enters onResume life cycle,
While the interface of triggering iqiyi.com video X enters onStop life cycle, the broadcast interface starting of triggering live telecast Y.
Further, if live telecast Y is to start for the first time, live telecast Y enters onCreate life cycle,
Subsequently into onStart life cycle；If live telecast Y is not to start for the first time, live telecast Y is directly entered
OnStart life cycle.
Further, while live telecast Y enters onStart life cycle, live telecast Y enters foreground, touches simultaneously
Hair intermediate interface E enters onPause life cycle, and then intermediate interface E exits foreground and enters backstage, final intermediate interface E
Into onStop life cycle.While live telecast Y enters foreground, stop the broadcast window of switching animation file, the intelligence
The display screen of TV shows the interface content of live telecast.
After live telecast Y enters onStart life cycle, live telecast Y inquires the state of audio/video decoder R, if
Live telecast Y inquires the state of audio/video decoder as the free time, starts its corresponding live telecast player, to live telecast
Interface load after the completion of, live telecast Y enters onResume life cycle, after the starting of live telecast player, calls sound view
Frequency decoder R plays corresponding audio and video resources.
Therefore, the method for the switching audiovisual applications of the embodiment of the present invention, the switching time of audiovisual applications are centre
