Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
In describing the invention, relate to accompanying drawing, unless otherwise stated, what the same numbers in different accompanying drawing represented is same or like invention key element.
The embodiment of the present invention provides a kind of method switching audiovisual applications, it is adaptable to have the terminal unit of intelligent operating system, example, such as has the intelligent television of Android operation system, smart mobile phone etc..Example, in the description of the embodiment of the present invention, it is described in detail for intelligent television, but does not represent and the present invention is limited to intelligent television.
Fig. 3 illustrates the one switching audiovisual applications schematic flow sheet that the embodiment of the present invention provides.With reference to shown in Fig. 3, the flow process of this switching audiovisual applications includes:
Step 100: receive the instruction switching to target sound Video Applications.
Concrete, intelligent television receives the control instruction that user sends, and this control instruction indicating intelligent TV exits current audiovisual applications, and is switched to target sound Video Applications.Example, if this intelligent television has touch-control control technology, user can input this switching command by the contact panel of this intelligent television；If this intelligent television has voice control technology, user can input this switching command by the speech control module of this intelligent television；No matter whether this intelligent television has touch-control control technology and voice control technology, and user sends this switching command such as through remote controller.Example, it is described in detail sending this switching command by remote controller to intelligent television for user the execution process of step 100 below.
Example, the execution process of step 100 is particularly as follows: intelligent television receives the remote controller key assignments that user sends, and then intelligent television obtains the target sound Video Applications that this remote controller key assignments is corresponding.Concrete, intelligent television, after receiving the remote controller key assignments that user sends, is searched the corresponding relation list of its remote controller key assignments configured and application identities, is obtained the application identities of this intended application corresponding to remote controller key assignments, example, this application identities is the Apply Names of this intended application.Example, the corresponding relation of remote controller key assignments and application identities is listed as follows shown in table table one.
| Remote controller key assignments | Corresponding Apply Names |
| KeyEvent 1 | Audiovisual applications A |
| KeyEvent 2 | Audiovisual applications B |
| KeyEvent 3 | Audiovisual applications C |
| KeyEvent 4 | Application D |
Example, in the process of intelligent television playing audio-video application A, receive the remote controller key assignments KeyEvent3 that user is sent by remote controller, after receiving this key assignments, the corresponding relation list table one of intelligent television inquiry remote controller key assignments and application identities, the target sound Video Applications obtaining this remote controller key assignments corresponding is audiovisual applications C, and namely intelligent television receives the instruction switching to target sound Video Applications C, then enter into step 110 and perform.
Step 110: start preset intermediate interface, and the audiovisual applications being being currently used is set to background program.
Concrete, in the execution process of step 110, start preset intermediate interface, the audiovisual applications being being currently used is set to background program simultaneously.Example, this intelligent television is being currently used audiovisual applications A, such as, it is being currently used the strange skill video of love, when receiving remote controller key assignments KeyEvent3, namely have received the instruction switching to target sound Video Applications C, such as, target sound Video Applications C is Tengxun's video, now, start preset intermediate interface, and strange for love skill video is set to 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 sound Video Applications, therefore the start-up loading speed of intermediate interface is faster than the start-up loading speed of target sound Video Applications.Example, intermediate interface only includes a layout control and a small amount of interface content, to realize the quick loading of intermediate interface.Preferably, intermediate interface does not comprise any interface content, is only a layout control, and namely intermediate interface is a blank interface, improves the loading velocity of intermediate interface further.
When entering foreground after intermediate interface has started, the interface triggering the audiovisual applications A being being currently used is suspended, and then audiovisual applications A exits into background program, it should be noted that, in Android operation system, entrance backstage, foreground is exited at the interface of current audiovisual applications A, it is necessary to an interface has started entrance foreground and triggered.
Step 120: described intermediate interface loaded, triggers the described audiovisual applications being set to background program and discharges described audio/video decoder, and start the broadcast interface of described target sound Video Applications.
Concrete, in Android operation system, after currently used audiovisual applications A enters backstage, the process of unlocking noise Video Decoder a, it is desirable to have interface entering foreground has loaded and triggered.When the intermediate interface entering foreground has loaded, trigger the audiovisual applications A entering backstage and stop using the player of its correspondence, and then audiovisual applications A starts unlocking noise Video Decoder.
Example, strange skill video is liked for third party's audiovisual applications for audiovisual applications A, in step 110, after intermediate interface launches into foreground, the strange skill video of love being being currently used exits entrance backstage, foreground, when the intermediate interface entering foreground has loaded, triggers and is positioned at the strange skill video player of love that the strange skill video of love on backstage stops using its correspondence, after liking that strange skill video player is stopped using, start the audio/video decoder that release likes that strange skill video takies.
Due in Android operation system, after currently used audiovisual applications enters backstage, the process of unlocking noise Video Decoder, need an interface entering foreground to have loaded and trigger, and the intermediate interface of the embodiment of the present invention is a lightweight interface, its interface content is less than the interface content of target sound Video Applications, therefore the loading velocity of intermediate interface is faster than the loading velocity at target sound Video Applications interface, therefore, the intermediate interface of the embodiment of the present invention can realize quick loading after entering foreground, and then trigger the audiovisual applications unlocking noise Video Decoder being being currently used, unlocking noise Video Decoder can be triggered in advance, and then shorten the waiting time of trigger tone Video Decoder release.
The intermediate interface entering foreground has loaded, and while the audiovisual applications A on triggering entrance backstage starts to discharge its audio/video decoder taken, the broadcast interface of trigger target audiovisual applications B starts.After the broadcast interface of target sound Video Applications B launches into foreground, triggering intermediate interface and exit entrance backstage, foreground, target sound Video Applications B starts to load its interface content simultaneously.
Need exist for illustrate be, after the intermediate interface on entrance foreground has loaded, first the broadcast interface of audiovisual applications B is started, rather than directly adopt audiovisual applications B to play corresponding audio and video resources, because audiovisual applications B and audiovisual applications A is likely to share an audio/video decoder, when the broadcast interface of audiovisual applications B is set to currently playing interface, the audiovisual applications A being switched to running background might not release its decoder resources occupied, so after execution of step 120, need whether the state judging audio/video decoder is idle, if the state of audio/video decoder is idle, then enter step 130.
Intelligent television for Android operation system, Android operation system is only provided with a decoder, certainly, other operating system also generally only arranges decoder, such as an IOS, even if being provided with in the operating system of two decoders at some, it is also possible to that the situation that two audiovisual applications share a decoder resources occurs, so terminal unit is had a decoder by the embodiment of the present invention, or two decoders, or multiple decoder does not limit.
For avoiding audiovisual applications A and audiovisual applications B to share same audio/video decoder, the embodiment of the present invention is after starting the broadcast interface of target sound Video Applications B, the state of audio/video decoder is inquired about, and as shown in Figure 4, concrete query steps can be:
Step 201: calling the interface that audio/video decoder is corresponding, in detection preset time threshold, whether this interface has code stream to export；
Step 202: if this interface exports without code stream, then judge that the state of audio/video decoder is as idle.
Intelligent television can call the corresponding interface of its audio/video decoder, by detecting whether this interface has code stream to export in preset time threshold, judge whether this audio/video decoder discharges complete, namely by judging whether audio/video decoder has audio, video data to export, it is determined that whether audiovisual applications A releases the audio/video decoder that it is shared.Concrete, if the interface of audio/video decoder does not have audio, video data to export in preset time threshold, then illustrate that audiovisual applications A has released its shared audio/video decoder, namely the state of audio/video decoder is idle；If it is determined that the interface to audio/video decoder has audio, video data to export in preset time threshold, then illustrating that audiovisual applications A does not discharge its shared audio/video decoder completely, namely the state of audio/video decoder is busy.
Specifically in the process performing step 201, if be detected that the interface of audio/video decoder has audio, video data to export in preset time threshold, then according to default polling cycle, circulation performs step 201, namely according to whether the interface of preset time period cycle detection audio/video decoder has audio, video data to export in preset time threshold, until detecting that the interface that in preset time threshold, audio/video decoder is corresponding exports without code stream, entering step 202 and performing.
Example, default polling cycle could be arranged to 250ms, certainly, in order to play target sound Video Applications B as early as possible, it is possible to what arranged default polling cycle is shorter, such as 200ms.
It should be noted that, when implementing, default polling cycle can also set the variable cycle, as first time inquires about with 250ms for preset time period, second time is inquired about with 200ms for preset time period, and third time carries out inquiry etc. with 150ms for preset time period, so, the state of decoder can be obtained quickly, once the state of decoder becomes the free time, it is possible to play target sound Video Applications faster.
It should be noted that preset time threshold can be random time length, example, preset time threshold can be 0.01ms, it is also possible to be 0.1ms, it is also possible to be 100ms, and the embodiment of the present invention does not limit for the specific size of preset time threshold.
When the state of decoder is idle, perform step 130: if the state of audio/video decoder is idle, it indicates that target sound Video Applications sends play instruction to this audio/video decoder.
nullAs can be seen from the above-described embodiment，After intelligent television receives the instruction switching to target sound Video Applications，Start preset intermediate interface，Intermediate interface triggers the audiovisual applications being being currently used and enters backstage after entering foreground，And then after intermediate interface loaded，Trigger the audiovisual applications entering backstage and discharge its audio/video decoder taken，And start the broadcast interface of target sound Video Applications，After audio/video decoder discharges，Target sound Video Applications sends play instruction to audio/video decoder，The handoff procedure of this audiovisual applications terminates，Therefore the audiovisual applications of the embodiment of the present invention is start-up loading time sum release time with audio/video decoder of intermediate interface switching time，And sum release time of the interface start-up loading time that switching time is target sound Video Applications of audiovisual applications of the prior art and audio/video decoder，Owing to the interface content of intermediate interface is fewer than the interface content of target sound Video Applications，Therefore，The start-up loading time of intermediate interface is shorter than the start-up loading time of target sound Video Applications，So the audio-video switching method of the embodiment of the present invention shortens the switching time between audiovisual applications，Shorten the waiting time of target sound Video Applications，Improve the user experience of intelligent television.
Further, before step 110, after this intelligent television receives the instruction switching to target sound Video Applications, the display screen of this intelligent television presents application switching animation, owing to the window level of animation broadcast window is higher than the window level of audiovisual applications, the interfaces windows of audiovisual applications is in invisible mode, therefore, the intermediate interface started in the step 120 will not be seen by the user in whole changing interface process, improves the user experience of the switching audiovisual applications of the embodiment of the present invention.
Example, this application switching animation can be the animation file being preset in this intelligent television, it is also possible to for using the sectional drawing of preset picture or application program, add the file of the animation effects such as amplification, slip, diffusion.
For the method better describing the switching audiovisual applications of the embodiment of the present invention, it is described in detail below in conjunction with specific example.
For the intelligent television with Android operation system, this intelligent television current is currently in use the strange skill video X of love and plays " rural area love ", and user wants that this intelligent television is switched to live telecast Y plays " all over the world football ", after this intelligent television receives the instruction switching to live telecast Y, concrete switching flow is as shown in Figure 5.
With reference to shown in Fig. 5, after this intelligent television receives the instruction switching to live telecast Y that user sends, the intermediate interface E transmission enabling signal that switch controller Z-direction is preset, switch controller Z controls the switching animation file that the broadcasting of this intelligent television is preset simultaneously, the broadcast window level of this switching animation file is higher than the broadcast window level of the broadcast window level and live telecast Y of liking strange skill video X, therefore, in whole handoff procedure, the display screen of this intelligent television shows the broadcast interface of switching animation file.
Further, after this preset intermediate interface E receives the enabling signal that switch controller sends, if this intermediate interface E starts first time, then this intermediate interface E enters onCreate life cycle (creating the cycle), subsequently into onStart life cycle (starting the cycle)；If this intermediate interface E starts first time, then this intermediate interface E is directly entered onStart life cycle (starting the cycle).
Example, this intermediate interface E is a blank interface, only includes a layout control, without concrete interface content, therefore, onCreate life cycle and the onStart life cycle duration of this intermediate interface E are very short, and this intermediate interface E can be entered foreground by quick pull-up.
Further, while this intermediate interface E enters onStart life cycle, trigger and like that the interface of strange skill video X enters onPause life cycle (pause period), and then like that foreground is exited at the interface of strange skill video X, enter backstage.After the onStart life cycle of intermediate interface E terminates, intermediate interface E enters onResume life cycle (life cycle) after having loaded, when intermediate interface E enters onResume life cycle, trigger the interface liking strange skill video X entering backstage and enter onStop life cycle (dwelling period).Liking that the interface of strange skill video X enters after onStop life cycle, and then stop and discharging the player of its correspondence, then the audio/video decoder R shared by strange skill video is liked in release.When intermediate interface E enters onResume life cycle, triggering while liking that the interface of strange skill video X enters onStop life cycle, the broadcast interface triggering live telecast Y starts.
Further, if this live telecast Y starts first time, then live telecast Y enters onCreate life cycle, subsequently into onStart life cycle；If live telecast Y starts first time, then live telecast Y is directly entered onStart life cycle.
Further, while live telecast Y enters onStart life cycle, live telecast Y enters foreground, triggers intermediate interface E simultaneously and enters onPause life cycle, and then this intermediate interface E exits entrance backstage, foreground, final intermediate interface E enters onStop life cycle.While live telecast Y enters foreground, stop the broadcast window of switching animation file, the interface content of the display screen display live telecast of this intelligent television.
After live telecast Y enters onStart life cycle, live telecast Y inquires about the state of audio/video decoder R, if it is the free time that live telecast Y inquires the state of audio/video decoder, start the live telecast player of its correspondence, after the interface of live telecast has loaded, live telecast Y enters onResume life cycle, after live telecast player starts, calls audio/video decoder R and plays corresponding audio and video resources.
Therefore, the method of the switching audiovisual applications of the embodiment of the present invention, the switching time of its audiovisual applications is start-up loading time sum release time with audio/video decoder R of intermediate interface E, and sum release time of the interface start-up loading time that switching time is live telecast Y of audiovisual applications of the prior art and audio/video decoder R, owing to intermediate interface E is blank interface, do not include any interface content, therefore, the start-up loading time than the live telecast Y start-up loading time of intermediate interface E is short, so the audio-video switching method of the embodiment of the present invention shortens the switching time between audiovisual applications, shorten the waiting time of target sound Video Applications, improve the user experience of intelligent television..
Based on identical inventive concept, the embodiment of the present invention additionally provides a kind of device switching audiovisual applications, as shown in Figure 6, this device includes: receiver module 301, execution module 302, judge module 303, control module 304 and detection module 305, wherein, receiver module 301 is for receiving the instruction switching to target sound Video Applications；Perform the module 302 instruction for receiving according to receiver module 301, start preset intermediate interface, and the audiovisual applications being being currently used is set to background program, and during for intermediate interface loaded, trigger the audiovisual applications being set to background program and discharge its audio/video decoder taken, and start the broadcast interface of target sound Video Applications；Whether judge module 303 is idle for judging the state of audio/video decoder；Controlling module 304 for when the state of audio/video decoder is idle, instruction target sound Video Applications sends play instruction to audio/video decoder.
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 sound Video Applications, therefore the start-up loading speed of intermediate interface is faster than the start-up loading speed of target sound Video Applications.Example, intermediate interface only includes a layout control and a small amount of interface content, to realize the quick loading of intermediate interface.Preferably, intermediate interface does not comprise any interface content, is only a layout control, and namely intermediate interface is a blank interface, improves the loading velocity of intermediate interface further.
Further, detection module 305 is used for detecting whether audio/video decoder interface has code stream to export in preset time threshold, and testing result is sent to judge module 304, and then, the testing result that the detection module 305 that judge module 304 receives sends is that audio/video decoder interface exports without code stream in preset time threshold, then the state of audio/video decoder is idle.
Concrete, detection module 305 can call the corresponding interface of audio/video decoder, by detecting whether this interface has code stream to export in preset time threshold, judge whether this audio/video decoder discharges complete, namely by judging whether audio/video decoder has audio, video data to export, it is determined that the state of audio/video decoder.If the interface of audio/video decoder does not have audio, video data to export in preset time threshold, then illustrate that the state of audio/video decoder is the free time；If the interface of audio/video decoder has audio, video data to export in preset time threshold, then illustrate that the state of audio/video decoder is busy.
If detection module 305 detects that the interface of audio/video decoder has audio, video data to export in preset time threshold, then according to whether the interface of default detection loop cycle detection audio/video decoder has audio, video data to export in preset time threshold, until detecting that the interface that in preset time threshold, audio/video decoder is corresponding exports without code stream.
Example, default polling cycle could be arranged to 250ms, certainly, in order to play target sound Video Applications B as early as possible, it is possible to what arranged default polling cycle is shorter, such as 200ms.
It should be noted that, when implementing, default polling cycle can also set the variable cycle, as first time inquires about with 250ms for preset time period, second time is inquired about with 200ms for preset time period, and third time carries out inquiry etc. with 150ms for preset time period, so, the state of decoder can be obtained quickly, once the state of decoder becomes the free time, it is possible to play target sound Video Applications faster.
It should be noted that preset time threshold can be random time length, example, preset time threshold can be 0.01ms, it is also possible to be 0.1ms, it is also possible to be 100ms, and the embodiment of the present invention does not limit for the specific size of preset time threshold.
Alternatively, receiver module 301 is specifically for receiving the control instruction switching to target sound Video Applications that user sends, and this control instruction exits, for indicating intelligent TV, the audiovisual applications being being currently used, and is switched to target sound Video Applications.
