Fig. 2 is referred to, in one exemplary embodiment, a kind of signal source switch method is applied to implementation environment shown in Fig. 1
Terminal 100, this kind of signal source switch method can perform by terminal 100, be may comprise steps of：
Step 310, terminal intercepts the switching command of user's trigger action generation that meets with a response, and is believed by target is obtained in switching command
Number source mark.
So that terminal is as intelligent television as an example, intelligent television can export the audio, video data corresponding to multiple signal source, letter
Number source can be traditional TV signal source, and such as cable television, DTV, ATV, HDMI, AV, DVD, VGA etc. can also be
The virtual signal source configured in emerging all kinds of Video Applications, i.e., the web page address that various video websites are provided（URL addresses,
Uniform Resource Locator addresses）, user can enter according to the signal source to intelligent television that is actually needed of oneself
Row switching.
When user needs to switch the signal source of intelligent television, user can pass through the control device that intelligent television is configured
The various signal sources being set out in user interface are selected to carry out switching signal source, or, set on control device by clicking on
The signal source button put（Such as HDMI buttons）Carry out the switching of signal source（For example switch to HDMI TV signal sources）, and or
Person, selects the mounted various applications presented in user interface to carry out the switching of signal source by control device.
Wherein, control device can be remote control, can also be wired/wireless mouse or keyboard.
By the above-mentioned selection operation or clicking operation that respond user, terminal can intercept the user triggering behaviour that meets with a response
The switching command that work is generated, to complete follow-up signal source hand-off process according to the switching command.
Further, when user selects the signal source for wishing to handover in user interface, by responding user
Selection operation generate corresponding switching command, will include corresponding to the signal source that this wishes to handover in the switching command
Mark, i.e. target signal source mark.Or, user clicks on the signal corresponding to the signal source for wishing to handover on control device
Source button, by responding user's click signal source button corresponding switching command is generated, will be comprising the signal in the switching command
The mark of signal source corresponding to the button of source, i.e. target signal source are identified.
Based on this, after intercepting and obtaining switching command, you can by target signal source mark is obtained in switching command, with this
The signal source that user wishes to handover to is known, so as to be conducive to being actually needed the switching for carrying out signal source according to user.
Step 330, obtains current demand signal source mark in the database file of terminal itself.
The database file of terminal itself is used for the record information related to user operation, to facilitate user behaviour next time
Make.For example, the historical information that user watches video can be recorded in database file, the currently viewing video of user can also be recorded
Playing progress rate etc., to facilitate subsequent user to watch again.
So-called current demand signal source identifies the signal source for representing corresponding to the currently viewing video of user, therefore, deserve
Front signal source mark is also by record in the database file of terminal itself.
By making a look up in the database file of terminal itself, you can current demand signal source mark is obtained, so as to favourable
The current demand signal source is identified into corresponding signal source in subsequent terminal and switches to signal source desired by user.
Step 350, when target signal source mark is differed with current demand signal source mark, checks whether the default switching of satisfaction
Condition.
If target signal source mark is identical with current demand signal source mark, then it represents that the signal source that user wishes to handover to is not sent out
Changing, now, terminal need not carry out the switching of signal source.
If target signal source mark is different from current demand signal source mark, then it represents that the signal that user wishes to handover to is new
Signal source, now, terminal will continue the switching of follow-up signal source.
It is appreciated that user is when video is watched, due to being affected by its place network environment, it may be desirable to continually
Switch between different signal sources, be both likely to be and switched between traditional TV signal source, such as by AV
Signal source switches to HDMI signal sources, it is also possible to carried out between the virtual signal source that different video class applications is configured
Switching, a web page addresses of such as a applications switch to the b web page addresses of b applications.
If excessively frequently signal source switching is all responded one by one terminal-pair, the negative of final drive layer can be greatly increased
Load, and cause signal source switching reaction slow so that the stand-by period of user is long, and causes poor user experience.
For this purpose, in the present embodiment, before the switching of signal source is carried out, terminal will carry out whether default switching condition meets
Inspection, with this optionally to excessively frequently signal source switching process, i.e. the only switching command meeting of finite number of time
The response of terminal is obtained, and then follow-up signal source hand-off process is completed by the switching command for responding.
For example, default switching condition can be do not intercept within default switching time meet with a response user's trigger action and
Other switching commands for generating.Represent that user does not continually carry out letter within default switching time if default switching condition is met
The switching in number source, now, terminal can be responded to detecing audible switching command before this, i.e., carry out letter into step 370
Number source hand-off process.
If obtaining other switching commands, table conversely, being unsatisfactory for default switching condition and intercepting within default switching time
Show that within default switching time user has carried out the switching of signal source more than once, now, terminal will not be to intercepting before this
To switching command responded, i.e., do not carry out signal source hand-off process, the burden of final drive layer is mitigated with this, so as to favourable
In the stand-by period for shortening user, the experience of user is improved.
Certainly, in other application scene, for example, although user have switched video class application by control device,
Signal source corresponding to the same video of its selected viewing does not change in fact, and now, terminal can not be to detecing before this
Audible switching command is responded, i.e., do not carry out signal source hand-off process.Correspondingly, it is same video to preset switching condition
The signal source mark of corresponding signal source is differed.
If meeting default switching condition represents that the signal source corresponding to the same video of the selected viewing of user is new
Signal source, now, terminal will be responded to detecing audible switching command before this, i.e., carry out signal source into step 370 and cut
Change process.
It is noted that in the application scenarios, the signal source of the signal source corresponding to same video is identified only for this
Same video is without concerning application, and target signal source mark involved before and current demand signal source mark are all not only for regarding
Frequency is also directed to application.
For example, it is the corresponding c signal source of a application b videos before switching, is the corresponding c letters of b application b videos after switching
Number source, then current demand signal source be designated a.b.c, target signal source is designated b.b.c, regardless of whether a applications or b applications, b videos
The signal source mark of corresponding signal source is b.c.Now, terminal will not carry out signal source hand-off process, and be to continue with defeated
Go out the audio, video data corresponding to c signal source.
Step 370, according to target signal source mark signal source hand-off process is carried out.
After the default switching condition of satisfaction is checked, terminal will carry out signal source hand-off process, will current demand signal source
Identify corresponding signal source and switch to the corresponding signal source of target signal source mark.
By process as above, the selectivity for realizing the switching of terminal-pair signal source is processed, i.e., terminal is only default
Signal source hand-off process is just carried out when switching condition is satisfied, the burden of final drive layer is alleviated with this so that terminal can
User's continually trigger action is quickly responded, so as to be effectively improved signal source switching efficiency, the experience of user is improve.
Fig. 3 is referred to, in one exemplary embodiment, step 350 may comprise steps of：
Step 351, judges whether terminal is intercepted other for user's trigger action generation that meets with a response and cut within default switching time
Change instruction.
If as it was previously stated, terminal-pair signal source switching each time is all responded, final drive layer can be greatly increased
Burden, and cause signal source switching reaction slow so that the stand-by period of user is long, and causes poor user experience.
For this purpose, in the present embodiment, terminal is only rung to the corresponding switching command for generating of last time signal source switching
Should, i.e., terminal will be referred to by other switchings for judging whether to intercept user's trigger action generation that meets with a response in default switching time
Make realizing the selective response to switching command.Correspondingly, default switching condition was not intercepted within default switching time
Other switching commands that the user's trigger action that meets with a response is generated.
Specifically, within default switching time, if terminal does not intercept other for user's trigger action generation that meets with a response
Switching command, expression detects before this audible switching command and is the corresponding generation of last time signal source switching, then enter
Step 353 judges to meet default switching condition, and terminal can be responded to the switching command, and with this follow-up signal source is completed
Hand-off process.
If conversely, terminal is within default switching time, also listening to have obtained to respond that user's trigger action generates that other are cut
Instruction is changed, represents that user has also carried out multiple signal source switching in the default switching time, then judge default into step 355
Switching condition is unsatisfactory for, and terminal will be ignored detects before this audible switching command, so as to not carry out at follow-up signal source switching
Reason.
More preferably, default switching time could be arranged to the minimum duration of the signal source switching that final drive layer tolerated,
Avoid final drive layer from excessively continually carrying out signal source hand-off process with this, effectively mitigate the burden of final drive layer.
Further, by the way that sequence number can be included in the switching command that generates in response to user's trigger action, in order to
Each switching command is mutually distinguishable so that terminal is capable of deciding whether to intercept other switchings of switching command before being different from
Instruction.For example, within default switching time, if terminal also listens to obtain the switching command of serial number 2,3,4,5, then it represents that use
Family has also carried out the associated trigger operation of four signal source switchings within this time, and terminal enters step 355, judges discontented
The default switching condition of foot, and then the switching command to detecing audible serial number 1 before this is not responded, i.e., do not carry out follow-up
Signal source hand-off process.
Step 353, judges to meet default switching condition.
Step 355, judgement is unsatisfactory for default switching condition.
It should be appreciated that terminal-pair detects audible each switching command by execution step 310 to step 350.When detecing
Be audible in response to user continually trigger action and generate multiple switching commands when, only last switching command can
Meet default switching condition, i.e., do not intercept obtaining other switching commands within default switching time.Now, terminal will ignore this
Other all switching commands before last switching command, and only last switching command is responded, to enter
Complete to one step follow-up signal source handoff process.
By process as above, respond switching command, i.e. user with realizing terminal selectively excessively continually enter
When row signal source switches, terminal is only responded to the corresponding switching command for generating of last time signal source switching, thus greatly
The burden of final drive layer is alleviated greatly, the response speed of signal source switching is effectively improved, when shortening the wait of user
Between, so as to be effectively improved the experience of user.
Fig. 4 is referred to, in one exemplary embodiment, step 370 may comprise steps of：
Step 371, the hardware resource of release busy, the hardware resource of the occupancy distributes to current demand signal source and identifies corresponding signal
Source.
It should be appreciated that current demand signal source identifies corresponding signal source can be considered current demand signal source, target signal source mark
Corresponding signal source can be considered target signal source, represent signal source to identify merely to being conducive to audio-video signal to transmit
During signal identifing source.
After terminal judges the default switching condition of satisfaction, terminal will carry out signal source hand-off process i.e. by current demand signal source
Target signal source is switched to, so that subsequent terminal can export the audio, video data corresponding to target signal source.
Based on this, the audio, video data corresponding to current demand signal source will no longer outlet terminal, current demand signal source also will no longer
Need to take any hardware resource, that is, distributing to its hardware resource can be released, so that hardware money limited in terminal
Source can be fully utilized, and for example, the hardware resource shared by current demand signal source being released can be again assigned to mesh
Mark signal source.
Step 373, is that target signal source identifies corresponding signal source distribution hardware resource.
In order that subsequent terminal can export the audio, video data corresponding to target signal source, terminal will be target signal source
Distribution hardware resource.
The hardware resource for distributing to target signal source can be idle hardware resource, can also be during release
Hardware resource.
It should be noted that in other application scenarios, in order to shorten the stand-by period of user, terminal can also first be held
Row step 373, as target signal source distribute hardware resource, then execution step 371, or while execution step 371 and step
373, the present embodiment is not any limitation as to this.Now, the hardware resource for distributing to target signal source is preferably idle hardware
Resource.
Certainly, signal source hand-off process includes but is not limited to the release and distribution of hardware resource, is additionally may included in terminal
Target signal source mark is updated into current demand signal source mark etc. in the database file of itself, the present embodiment does not add to this
To limit.
By process as above, realize signal source handoff process, i.e. signal source and switched by current demand signal source
To target signal source.
Fig. 5 is referred to, in one exemplary embodiment, method as above can also be comprised the following steps：
Step 375, judges whether the hardware resource for taking discharges and finishes.When the hardware resource for determining occupancy discharges and finishes,
Into step 373.
Because the hardware resource of release busy needs the regular hour, therefore, in the present embodiment, the hardware resource of occupancy is
The judgement that no release is finished will be completed by timer.
Specifically, a timer will be set in terminal, when the hardware resource of release busy is started, timer initiation,
When the timing numerical value of timer reaches preset stopping numerical value, timer stops timing, now judges that the hardware resource for taking is released
Discharge complete.
When the hardware resource for determining occupancy discharges and finishes, into the hardware resource of step 373 performance objective signal source
Distribution.
Conversely, when the hardware resource for determining occupancy does not discharge and finishes, return to step 371 continues the hardware of release busy
Resource, that is, keep timer to continue timing.
By process as above, the hardware resource distribution of target signal source has to wait for the hardware resource release for taking
Can carry out after finishing, hardware resource efficiently avoid with this and use conflict（For example when hardware resource is not enough, do not discharge
The hardware resource for finishing is allocated to target signal source）Problem, it is ensured that will not produce in signal source handoff process
, for example, there are two kinds of sound in the not positive problem of signal source after signal source hand-off process, and then is effectively improved signal source switching
Stability, improve the experience of user.
In one exemplary embodiment, method as above can also be comprised the following steps：
The corresponding audio, video data of signal source after output switching process.
Wherein, the signal source after hand-off process both can be target signal source, or current demand signal source.Can manage
Solution, if what is still exported in terminal is the audio, video data corresponding to current demand signal source, then it represents that terminal is not audible to detecing
Switching command is responded.
