It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of switching method of television signal source.It is television signal source of the present invention shown in referring to Fig.1
Switching method first embodiment flow chart.
In the present embodiment, the switching method of the television signal source includes:
Step S10, when receiving signal source switching command, first host process in current demand signal source is closed in operation, simultaneously
The first secondary process and the second secondary process in current demand signal source are closed in operation；
It should be noted that the switching method of television signal source proposed by the present invention is suitable for various television sets, such as
DTV, smart television with intelligent operating system etc..It is illustrated taking a smart TV as an example below, but the present invention is simultaneously
It is not limited in this.
User can be based on the signal source toggle control or setting that the remote control device of television set is arranged on a television set
Signal source switching key trigger signal source switching command.For TV sets, when receiving signal source switching command, operation
First host process, the first host process include each operation closely related with current demand signal source, specifically, run the first host process
I.e. television set executes following steps:
Currently playing audio and video are closed, the detection in the current demand signal source is stopped, and close the current demand signal
The channel in source.
Close the process in current demand signal source are as follows: close currently playing audio and video, avoid subsequent picture in the process
It situations such as will appear flower screen, closes after sound and just stops the signal detection in current demand signal source, general smart television is working
When, currently used signal source can be detected, for example, whether the signal of sensed signal sources locks, the format of signal, signal
Variation etc., want the detection of stop signal at this time, that is to say, that otherwise the detection for stopping above-mentioned every content will lead to letter
There is mistake in number service, for example, signal intensity can cause the mistake of signal detection service to execute.About stopping detecting, that is, control
Stop executing respective function with each service module.After the completion of the detection to current demand signal source stops, current demand signal is closed
The channel in source.
While running the first host process, the secondary process of operation first, the first secondary process is to close and current signal source
Relevant some services, consuming time is long for such as some execution, but the clothes that will not be impacted to the host process of switching signal source
Business, specifically, the secondary process of operation first, i.e. television set execute following steps:
Stop the hbbtv service in the current demand signal source, and resets the output of SCART interface.
It is understood that some signal sources may need to open hbbtv (Hybrid Broadcast/Broadband
TV, a kind of content distribution platform compatible with DVB) it services, therefore, when running the first secondary process, hbbtv module is examined
It surveys, if the function of hbbtv module is currently at open state, stops the service of the module, if the module is inherently in pass
Closed state does not need then to execute any operation, continues to remain off.Similarly, it is exported about SCART interface
Reset, if having SCART interface export, resetted, otherwise do not need to execute any operation.
After the completion of stopping the detection in the current demand signal source, bring into operation the described second secondary process；
The secondary process of operation second, i.e. television set execute following steps:
Stop playing relevant each function to the program in the current demand signal source to complete the fortune of the described second secondary process
Row.
There may be unused function needs for the broadcasting of program for different signal sources, for example whether being provided with subtitle
Service, if played for 3D etc., the second secondary process mainly detects each function relevant to the broadcasting of the program in current demand signal source
Module stops its corresponding function if functional module is in the open state, for example, current demand signal source is ATV (simulation electricity
Depending on signal) or when DTV (digital television signal), then caption function can be stopped, such as CC (Closed Caption, the U.S.
The subtitle of standard) etc., teletext function is currently opened, the function can be also stopped, wherein teletext is that television text is wide
It broadcasts, is generally used in Europe；If opening 3D broadcasting, because next signal source not necessarily has 3D, generally also want
Stop 3D function.
Step S20, after the completion of first host process operation, operation opens the second host process of target signal source with complete
At the switching of television signal source, wherein when the channel in current demand signal source is closed, determine that first host process has been run
At after the state for completing target signal source saves, judgement the second host process operation is completed.
After the completion of the first host process, i.e., after the channel in current demand signal source is closed, can bring into operation the second host process, with
Open target signal source, it is to be understood that if the second secondary process does not run completion at this time, still can continue to run.Tool
Body, the second host process is run, i.e. television set executes following steps: detecting the signal of the target signal source；Detecting
When stating the signal of target signal source, the channel of the target signal source is opened, and saves the current state of the target signal source.
Starting echo signal source channels signal detection will be detected when the signal of target signal source changes, when
When detecting signal, the channel of target signal source is opened, saves the state of target signal source.Under normal circumstances, in echo signal
Before the channel in source is opened, the second secondary process has run through complete.
It is above-mentioned to constitute this with the first host process for closing current demand signal source and the second host process for opening target signal source
The host process of television set switching signal source in invention, i.e. this main flow are the essential process of switching signal source, and its
The correlation of each service and host process in his each secondary process is not very big, and does not need functionally to couple, therefore, can
It is performed simultaneously with concurrent with host process；In addition, the time that each service in secondary process often occupies is long, they are put
It is executed in secondary process, can greatly shorten the total time that signal source switching occupies.
Therefore, it before television set factory or when the signal source switching flow of television set is arranged, can according to need pre-
It first sets each function of needing to be implemented in host process and secondary process and host process, need to be implemented in each secondary process
Each function.
Further, after completing step S20, the switching method of the television signal source is further comprised the steps of:
After the completion of second host process operation, the third pair process of target signal source is opened in operation, described in completing
The setting of each function of target signal source.Specifically, third pair process is run, i.e. television set executes following steps: setting institute
State sound configuration, signal source reproduction ratio and the ratio mode of target signal source；The TV programme of starting and the target signal source
Play relevant each function, and update channel configured list；The locking of the target signal source is set, and judges the target
Whether signal source needs to open hbbtv service, if desired, then opens the hbbtv service of the target signal source.
After the channel of target signal source is opened, signal is tested, starts to carry out sound setting, at this time sound and image
Or pent, signal is lockable, and sound and image can just be opened；The reproduction ratio in following setting signal source is different
Signal source, display picture size be it is different, as ATV analog signal, due to the reason of interference, the matter at general edge
Amount be not very well, so fidelity factor can be small, as DTV, HDMI (High Definition Multimedia Interface,
Digitized video/audio interface technology) etc. digital signals, it is anti-interference can be relatively good, so reproduction ratio can be bigger, and PC signal
Reproduction ratio requirement be 100%.It next is exactly Set scale mode, if user has adjusted 4:3 or 16:9, switching signal
Just according to the ratio setting ratio mode of user setting after source, after being provided with, start OAD, CEC, CC, teletext, MTS
Deng service, wherein OAD is the function that television set upgrading is carried out using the channel DTV, and CEC is the communication between HDMI equipment, and MTS is
Beautiful sound detection service, beautiful sound are to broadcast close to instant reducing and expansion voice-frequency-multichannel.Then channel list is updated, is played for channel
It is ready work, if current demand signal source is lockable, that is last if it is desired to starting the service of hbbtv, with regard to starting
Hbbtv service.
After switching signal source is opened in real execution, as long as current signal source state is saved, even if switching signal source is complete
At subsequent sound setting, target signal source reproduction ratio, the functions such as ratio mode can gradually start, and these are serviced
All than relatively time-consuming, in order to which the fluency of user operates, it is possible to continue to execute from the background.
It is television set in the prior art when carrying out the switching of signal source referring to shown in Fig. 2, complete signal switching flow
Schematic diagram, referring to shown in Fig. 3, for according to the flow diagram of the switching of method proposed by the present invention progress signal source, the present invention
The switching of signal source is carried out in the form of multi-course concurrency, what host process will be influenced without, but can be than time-consuming
Service is put into secondary process and executes, for example, hbbtv service, the reset of SCART interface output etc., stop subtitle, CC,
The services such as teletext are also equally, not impact to main switching signal source, but can be than time-consuming, these functions
The execution time can be finished before opening signal source channels again, it is possible to concurrent execution.By writing code
Verifying, existing television signal source switches time-consuming 750ms, and uses method of the invention, and television set switching signal source only needs
200ms is wanted, the switch speed of signal source is greatly improved, shortens the time that signal source switching occupies.
The switching method for the signal source that the present embodiment proposes, when receiving signal source switching command, operation first it is main into
Journey is run the second host process to open target signal source, is cut with price television set by current demand signal source to close current demand signal source
Target signal source is shifted to, also, while running the first host process, the first secondary process and the in current demand signal source is closed in operation
Therefore second mate's process when carrying out the switching of signal source, multiple Process Synchronizations can be carried out, i.e., the mistake switched signal source
The each function division needed to be implemented in journey is the progress of multiple Process Synchronizations, and the operation of each secondary process will not make host process
At influence, therefore, synchronous operation that can be concurrent greatly improves the switch speed of signal source, shortens signal source switching
The time of occupancy, the signal source switch speed for solving existing television set is slow, the long technical problem of holding time.
The second embodiment of the switching method of television signal source of the present invention is proposed based on first embodiment.In the present embodiment
In, before the step of opening the channel of the target signal source, the switching method of the television signal source is further comprised the steps of:
When detecting the signal of the target signal source, judge whether the described second secondary process runs completion；
If the described second secondary process operation is completed, the channel for opening the target signal source is executed, and save the mesh
The step of marking the current state of signal source；
If after the completion of the second secondary process operation, the waiting that is delayed is until the described second secondary process executes completion, execution
The channel of the target signal source is opened, and the step of saving the current state of the target signal source.
Since for different signal sources, when playing TV programme, the function of setting is not quite similar, therefore, subtitle,
Therefore the stopping of the services such as CC, teletext, may detect before opening echo signal source channels there are no being finished
To target signal source signal when, first to judge whether secondary process runs completion, if operation complete, open the echo signal
The channel in source, and the current state of the target signal source is saved, otherwise delay waits until the described second secondary process has executed
At.
The present invention also proposes a kind of television set.
It is the functional block diagram of television set first embodiment of the present invention referring to shown in Fig. 4.

Secondary scheduler module 20, for after the completion of first host process operation, the second of target signal source to be opened in operation
Host process is to complete the switching of television signal source, wherein when the channel in current demand signal source is closed, determine described first it is main into
Cheng Yunhang is completed, and after the state for completing target signal source saves, determines that the second host process operation is completed.
It should be noted that television set proposed by the present invention can be various types of television sets, such as DTV, tool
There is the smart television etc. of intelligent operating system.Be illustrated taking a smart TV as an example below, but the invention is not limited in
This.
User can be based on the signal source toggle control or setting that the remote control device of television set is arranged on a television set
Signal source switching key trigger signal source switching command.For TV sets, when receiving signal source switching command, it is main into
Journey module 10 runs the first host process, and the first host process includes each operation closely related with current demand signal source, specifically, main
Scheduler module 10 runs the first host process, that is, represents television set and execute following operation: closing currently playing audio and video, stop
The only detection in the current demand signal source, and close the channel in the current demand signal source.
Host process module 10 closes currently playing audio and video, and subsequent picture in the process is avoided to will appear flower screen etc.
Situation, closes after sound and just stops the signal detection in current demand signal source, and general smart television at work, can be to currently making
Signal source is detected, for example, whether the signal of sensed signal sources locks, the variation of the format of signal, signal etc., this
When want the detection of stop signal, that is to say, that the detection for stopping above-mentioned every content, otherwise will lead to signal service occur it is wrong
Accidentally, for example, signal intensity can cause the mistake of signal detection service to execute.About stopping detecting, that is, control and each service mould
Block stops executing respective function.After the completion of the detection to current demand signal source stops, the channel in current demand signal source is closed.
While host process module 10 runs the first host process, the secondary process of the secondary operation of scheduler module 20 second, second is secondary
Process is to close some services relevant to current signal source, and consuming time is long for such as some execution, but will not believe switching
