Specific embodiment
The embodiment of the present invention is illustrated below in conjunction with attached drawing, it should be understood that embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistented with the present invention.On the contrary, they be only with it is such as appended
The example of device and method being described in detail in claims, some aspects of the invention are consistent.
The embodiment of the present invention provides a kind of method for switching audiovisual applications, suitable for setting with intelligent operating system
It is standby, such as smart television, smart phone, Intelligent flat computer etc., due to currently, smart phone, Intelligent flat computer etc. are generally logical
Touch screen mode controlling equipment is crossed, and smart television generally is equipped with remote controler, user can be sent out by remote controler to smart television
Send control instruction, control instruction can be the instruction of switching application, full frame displaying or broadcast on smart television in current application
In the case where putting, user can also send the instruction of switching application, therefore, intelligence to smart television by remote controller key
Energy TV does not have the smart machine of external control devices relative to other, and relatively convenient is applied in switching, and the present embodiment is just with intelligence
For energy TV, embodiments of the present invention will be described.As shown in figure 3, the method for switching application of the invention includes step
It is rapid:
S100: the instruction for switching to target audiovisual applications is received；
Taking a smart TV as an example, as shown in figure 4, this step includes following two steps:
S101: smart television receives the remote controler key assignments of user's transmission；
S102: smart television obtains target audiovisual applications corresponding with the remote controler key assignments received；
In step s 102, it implements are as follows: the mapping table of configured remote controler key assignments and application identities is searched,
Application identities corresponding with the remote controler key assignments received are obtained, application identities here are specifically as follows Apply Names.It is corresponding
Relation table are as follows:
The mapping table of table 1 remote controler key assignments and Apply Names
After step S102, the remote controler key assignments received is converted to answering for target audiovisual applications by smart television
With title, for example, having received the key value Key Event2 of remote controler transmission during smart television is played using A, connecing
After receiving key assignments, look-up table 1, obtaining the corresponding target audiovisual applications of key assignments keyEvent2 is then entered step using B
S200: according to instruction, start target audiovisual applications, that is, apply the broadcast interface of B, and the sound being currently played is regarded
Frequency is applied, that is, is set to background program using A, is made using A in running background.
In step s 200, in the actual operation process, while the broadcast interface of B is applied in starting, after being set to using A
Platform program executes it on backstage, for example, and it is such as Sohu's video using A, is LeEco video using B, it is distant when receiving
When controlling device key value Key Event2, start the broadcast interface of LeEco video, and Sohu's video is set to background program.
What needs to be explained here is that start the broadcast interface of LeEco video first after receiving switching command, rather than it is straight
It connects and plays LeEco video, because Sohu's video and LeEco video the two audiovisual applications may share an audio/video decoding
Device is switched to Sohu's video of running background and different when setting currently playing interface for the broadcast interface of LeEco video
Surely its decoder resources occupied is released, so entering step S300 after executing the step S200: inquiry audio/video decoding
The state of device.
By taking Android operation system as an example, a decoder is only provided in Android operation system, certainly, others operation
It is also general in system that a decoder, such as IOS operating system are only set, even if there are two the operations of decoder in some settings
In system, it is also possible to the case where two audiovisual applications share a decoder resources occur, so in the embodiment of the present invention
There is a decoder or two decoders or multiple decoders without limitation to smart machine.In the embodiment of the present invention
In, if receiving after switching to the instruction using B during smart television playing audio-video application A, then starting application
The broadcast interface of B, and background program will be set to using A, i.e., so that using A in running background.The broadcast interface of B is applied in starting
Afterwards, play instruction can be sent to decoder using B, that is, start play instruction, because needing to use solution in playing process using A
Code device can send stop instruction, i.e. stopping play instruction, because at this after being set to background program using A to decoder
In inventive embodiments, if being the user interface without homepage by user-interface design, just it is omitted during application switching
The step of being operated on homepage, thus start the broadcast interface using B and background program will be set in embodiments of the present invention using A
It almost carries out simultaneously, it is more likely that will appear while send play to decoder using B and instruct, using A to same
Decoder sends stop instruction, at this point, decoder can only respond one of instruction, sends if decoder has been responded using A
Stop instruction, it will cause decoders to stop working, and can not play target audiovisual applications B；Or application A is sent out to decoder
While sending stop to instruct, play instruction is sent to the same decoder using B, in this case, decoder can only also respond
One of instruction, so, when application B sends play to the same decoder and instructs, decoder is not received probably
The play instruction being sent to it using B, and the stop sent using A being in response to is instructed, also resulting in can not playing audio-video
Using B.
In order to avoid the above problems, the embodiment of the present invention is right after the broadcast interface of starting target audiovisual applications B
The state of audio/video decoder is inquired, as shown in figure 5, specific query steps can be with are as follows:
S501: the corresponding interface of audio/video decoder is called, detects whether the interface has code stream output；
S502: if the interface is exported without code stream, judge the state of audio/video decoder for the free time.Pass through decoder
Whether the interface polls interface has code stream, that is, inquires whether have audio, video data output, if the interface does not have audio-video
Data export, then illustrate to have released its decoder resources occupied using A, that is, can determine that the state of decoder for sky
It is not busy.Same reason illustrates that although having been switched to backstage using A executes, but releases not yet if the interface has code stream output
Its decoder resources occupied is put, can determine whether that the state of decoder is busy at this time.It is idle situation in the state of decoder
Under, it executes step S400: if the state of audio/video decoder is the free time, indicating target audiovisual applications to the audio-video solution
Code device sends play instruction.
As can be seen from the above-described embodiment, it after smart television receives the switching command of target audiovisual applications, is opening
While the broadcast interface of moving-target audiovisual applications, the audiovisual applications being currently played are switched into running background, this
Compared with prior art, the time of switching application is shortened to a certain extent, and further, the embodiment of the present invention is in starting target
After the broadcast interface of audiovisual applications, the state of audio/video decoder is inquired, and when the state of decoder is idle, is just broadcast
Target audiovisual applications are put, the target audiovisual applications after avoiding the audiovisual applications and switching being currently played are because possible
Share the same decoder resources bring resource conflict problem.
To sum up, since the embodiment of the present invention is after receiving switching command, target audiovisual applications can be directly switch into
Broadcast interface therefore, during application switching, homepage can be saved, i.e., without first returning to homepage before handover
The method of the switching audiovisual applications of the embodiment of the present invention eliminates the audiovisual applications -> homepage being currently played, and main
The step of page -> target audiovisual applications, moreover, starting to play target audiovisual applications, therefore, entirely in the decoder free time
During audiovisual applications switch, realizing decoder resources and being released to target audiovisual applications with application switching makes
With, that is, realize the normal play of target audiovisual applications, realizing application without homepage switch, simplify switch step
Meanwhile the resource conflict problem between also avoiding applying in handoff procedure.
In embodiments of the present invention, it is contemplated that when being withdrawn into backstage execution using A, its institute may not be able to be released immediately
The decoder resources occupied, therefore, when inquiring the state of decoder, decoder can available free and busy two states, work as decoding
The state busy of device, the embodiment of the invention provides two schemes balances using the decoder resources of A and application B.
The first scheme, as shown in fig. 6, specific steps are as follows:
S601: if the state of audio/video decoder be it is busy, query time interval is set；
Specifically when being executed, it can be set between query time and be divided into 250ms, certainly, in order to play target audio-video as early as possible
Using B, query time interval can be configured shorter, such as 200ms.
S602: to be divided into the period between the query time of setting, the state of audio/video decoder is inquired, and when the sound inquired
When the state of Video Decoder is idle, instruction target audiovisual applications send play instruction to audio/video decoder.
Using the 250ms of setting or 200ms as the period, the interface provided by system is inquired and is connect corresponding to decoder
Whether mouth has code stream, i.e. video data exports, and when the interface is exported without code stream, plays target audiovisual applications B.
It should be noted that the variable cycle can also be set when specific implementation, such as the first time using 250ms as query time
Interval is inquired, and is inquired for the second time by query time interval of 200ms, for the third time using 150ms as query time interval
Inquire etc., in this way, the state of decoder can be quickly obtained, once the state of decoder becomes idle, Ke Yigeng
Fast broadcasting target audiovisual applications.
Audiovisual applications in above-described embodiment, after the broadcast interface for switching to target audiovisual applications B, before switching
When A does not discharge decoder resources, setting polling cycle constantly inquires the state of decoder, until decoder states are the free time
When, target audiovisual applications B is just played, avoids the decoder resources conflict of switching front and back, therefore, the present embodiment is realizing
While switching without homepage of audiovisual applications, also utmostly ensure that the normal operation of system.
Second scheme, as shown in fig. 7, specific steps of the balance using A and application B are as follows:
S701: if the state of audio/video decoder be it is busy, by present system time be set as inquiry initial value；
S702: the clocking value of timer is read；
Taking a smart TV as an example, smart television generally has clock, can using the clock of smart television as timer, from
System time is read on the timer.Certainly, timer may be the timer being specially arranged, and be not especially limited here.
Regardless of the timer of which kind of form, it can be and just start after step S701, be also possible to smart television and just opened from booting
Dynamic, it is also not especially limited here.If the system time that the state of step S701 inquiry decoder is busy is 15:30,
Inquiry initial value is 15:30, hereafter, reads the clocking value of smart television clock in real time or periodically.
S703: when the clocking value of timer and the difference of inquiry initial value are more than or equal to inquiry duration threshold value, and sound
The state of Video Decoder is busy, and the audiovisual applications that instruction is set to background program are sent to audio/video decoder stops solution
After the instruction of code, instruction target audiovisual applications send play instruction to audio/video decoder.
In this step, inquiry duration threshold value can be set as 5000ms, under normal circumstances, inquiry duration threshold value is reference
User to switching duration tolerance setting, in order to guarantee the experience of user's cut bank, when the clocking value of timer with look into
The difference for asking initial value is more than or equal to 5000ms, and the state of the audio/video decoder is busy, that is to say, that from switching
Start to target audiovisual applications, after have passed through 5000ms, if the corresponding interface of decoder still has code stream output, at this moment intelligence
Energy TV will indicate that the audiovisual applications before switching send the instruction for stopping audio and video playing to decoder, so that releasing using A
Its audio and video resources occupied has been put, so that audio/video decoder is idle state, has indicated that target audio-video is answered at this time
Play instruction is sent to decoder with B, so that decoder is the audiovisual applications decoding after switching.
Optionally, in order to avoid influencing user experience, and also to system is avoided to be abnormal, inquiry duration here
Threshold value may be arranged as decoder resources and be released required average time, which can be with the busy journey of system
The change of degree and change.
In above-described embodiment, it is contemplated that the audiovisual applications before switching may be when being more than that user bears switching duration, still
Decoder resources cannot be discharged, therefore, are provided with inquiry duration threshold value, when the broadcast interface of starting target audiovisual applications, and
After inquiring the time of duration threshold value, if decoder resources are discharged still without the audiovisual applications before being switched, intelligence
After the audiovisual applications that TV instruction has been switched to running background send the instruction for stopping playing to decoder, instruction switching
Target audiovisual applications afterwards send play instruction to decoder, to play target sound video instructions.Further, when the inquiry
When duration threshold value is average time required for decoder resources are released, held because the average time is generally less than user
The maximum switching duration received, so, at this point, more can guarantee the experience of user, and because after certain interval of time, it is just mandatory
Decoder resources are distributed to target audiovisual applications by ground, so also can be reduced the probability that system is abnormal to a certain extent.
In this way, avoiding user after the broadcast interface of starting target audio-video, the audio-video before being switched because of decoder resources is occupied
Caused by target audiovisual applications the problem of cannot playing for a long time.
Based on identical inventive concept, the embodiment of the invention also provides a kind of television set TVs for switching audiovisual applications
Machine, as shown in figure 8, the television set television set includes: receiving module 801, for receiving the finger for switching to target audiovisual applications
It enables；Execution module 802, the instruction for being received according to receiving module 801 start the broadcast interface of target audiovisual applications,
And the audiovisual applications being currently played are set to background program；Enquiry module 803, for inquiring the shape of audio/video decoder
State, and the state of the audio/video decoder inquired is sent to judgment module 804；Judgment module 804 is received for basis
The state of audio/video decoder that sends of enquiry module 803, judge whether audio/video decoder is idle, and work as audio-video solution
When the state of code device is idle, message is sent to control module 805；Control module 805, for being sent according to judgment module 804
Message, instruction target audiovisual applications to audio/video decoder send play instruction.
Optionally, receiving module 801 is specifically used for receiving the remote controler key assignments of user's transmission, and what is obtained and receive is distant
Control the corresponding target audiovisual applications of device key assignments.
Wherein, acquisition target audiovisual applications corresponding with the remote controler key assignments received performed by receiving module 801
Step specifically: search the mapping table of configured remote controler key assignments and application identities, the remote controler for obtaining and receiving
The corresponding application identities of key assignments, application identities here are specifically as follows Apply Names.The mapping table such as embodiment of the present invention
Above-mentioned table 1.After smart television receives switching command, by look-up table 1, the concrete application name of target audiovisual applications is obtained
Claim.Later, broadcasting for target audiovisual applications is started according to the concrete application title of target audiovisual applications by execution module 802
Interface is put, and the audiovisual applications being currently played are set to background program.
What needs to be explained here is that starting the broadcasting of target audio-video first after receiving module 801 receives switching command
Interface, rather than target audio-video is directly played, because the two audiovisual applications of switching front and back share a decoder, when
When setting currently playing interface for the broadcast interface of target audio-video, the audiovisual applications for being switched to running background might not
Its decoder resources occupied is released, therefore, it is necessary to be executed the state of inquiry decoder by enquiry module 803.
In embodiments of the present invention, it sets the audiovisual applications before switching to using A, the audiovisual applications after switching are set
It is set to using B.If receiving module 801, which receives, to be switched to using B during smart television playing audio-video application A
Instruction after, then the broadcast interface of B is applied by the starting of execution module 802, and background program will be set to using A, i.e., so that using A
In running background.It needs to use decoder in playing process using A, it, can be to decoding after being set to background program using A
Device sends stop instruction, i.e. stopping play instruction, and after starting the broadcast interface using B, it can be sent out to the same decoder using B
It send play to instruct, that is, starts play instruction, and it is almost same using the broadcast interface of B by background program and starting is set to using A
Shi Jinhang's, it is more likely that will appear and first have sent play instruction to decoder using B, sent out again to the same decoder using A
Stop instruction has been sent, has been stopped working at this point, will cause decoder, target audiovisual applications B can not be played；Or application A first to
Decoder has sent stop instruction, play instruction is sent then to the same decoder using B, in this case, because using A
First to decoder have sent stop instruction, decoder receive stop instruction after, stopped work, so, application B with
When sending play instruction to the same decoder afterwards, decoder does not receive the play instruction being sent to it using B, also results in
It can not playing audio-video application B.
In order to avoid the above problems, the embodiment of the present invention starts the broadcasting of target audiovisual applications B in execution module 802
It after interface, is inquired provided with state of the enquiry module 803 to audio/video decoder, when specific implementation, in enquiry module
In be provided with detection module, the corresponding interface of decoder is called by detection module, detects whether the interface has code stream output, and will
Testing result is sent to judgment module 804.If the testing result of detection module is the interface without code stream output, that is, tone-off
Video data exports, then illustrates to have released its decoder resources occupied using A, judgment module 804 can determine that solution
The state of code device is the free time.Same reason illustrates to apply if the testing result of detection module is that the interface has code stream output
Although A has been switched to backstage and executes, but discharge its decoder resources occupied not yet, and judgment module 804 can at this time
Judge that the state of decoder is busy.In the case where the state of decoder is idle, judgment module 804 is sent out to control module 805
Send message, for example " 0 " represents the state of decoder as the free time, then judgment module 804 in the case where decoder states are idle,
" 0 " is sent to control module.The message that control module 805 is sent according to judgment module 804, then indicate target audiovisual applications to
Decoder sends play instruction.As can be seen from the above-described embodiment, when the receiving module of smart television 801 receives target sound view
After the switching command of frequency application, start the broadcast interface of target audiovisual applications by execution module 802, and will be currently played
Audiovisual applications switch to running background, this compared with prior art, shorten to a certain extent switching application time,
Further, the embodiment of the present invention is inquired by enquiry module 803 and is decoded after the broadcast interface of starting target audiovisual applications
The state of device, and when the state of decoder is idle, target audiovisual applications are just played, the sound being currently played is avoided
Target audiovisual applications after Video Applications and switching are because that may share the same decoder resources bring resource conflict problem.
To sum up, since the embodiment of the present invention is after receiving switching command, target audiovisual applications can be directly switch into
Broadcast interface start to play target audiovisual applications moreover, in the decoder free time, therefore, entire audiovisual applications switching
During, it realizes decoder resources and is released to the use of target audiovisual applications with application switching, that is, realize target
The normal play of audiovisual applications during application switching, can save homepage in turn, that is, eliminate and currently broadcasting
The step of audiovisual applications -> the homepage and homepage put -> target audiovisual applications, realizes switching without homepage for application, and letter
While having changed switch step, the resource conflict problem between the application in handoff procedure is also avoided.
