DTV, there is the intelligent television etc. of intelligent operating system.Illustrate as a example by intelligent television below, but the present invention is also
It is not limited in this.
User can the signal source toggle control that arranges of remote control unit of based on television set or arrange on a television set
Signal source switching key trigger signal source switching command.For television set, when receiving signal source switching command, run
First host process, the first host process includes each operation closely-related with current demand signal source, specifically, runs the first host process
I.e. television set execution following steps:
Close currently playing Voice & Video, stop the detection in described current demand signal source, and close described current demand signal
The passage in source.
The process closing current demand signal source is: close currently playing Voice & Video, it is to avoid picture during follow-up
There will be the situations such as Hua Ping, just stop the signal detection in current demand signal source after closing sound, general intelligent television is in work
Time, currently used signal source can be detected, such as, whether the signal of sensed signal sources pins, the form of signal, signal
Change etc., the detection of signal to be stopped, say, that stopping the detection of above-mentioned every content, otherwise can cause letter
There is mistake in number service, and such as, signal intensity can cause the mistake execution that signal detection services.About stopping detection, i.e. control
Stop performing respective function with each service module.After the detection in current demand signal source has been stopped, closing current demand signal
The passage in source.
While running the first host process, running the second secondary process, the second secondary process is to close and current signal source
Some relevant services, as long in some execution consuming times, but the clothes that the host process of switching signal source will not be impacted
Business, specifically, the secondary process of operation first, i.e. television set execution following steps:
Stop the hbbtv service in described current demand signal source, and the output of the SCART interface that resets.
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) service, therefore, when running the first secondary process, hbbtv module is examined
Survey, if the function of hbbtv module is currently at opening, then stop the service of this module, if this module is inherently in pass
Closed state, then need not perform any operation so that it is continue to remain off.Similarly, export about SCART interface
Reset, if there being SCART interface to export, being resetted, otherwise need not perform any operation.
After the detection stopping described current demand signal source completes, bring into operation the described second secondary process；
The secondary process of operation second, i.e. television set execution following steps:
Stop the fortune playing each relevant function to the program in described current demand signal source to complete the described second secondary process
OK.
No function needs are had, for example whether be provided with captions possibly for the broadcasting of program for different signal sources
Service, if for 3D broadcasting etc., the second secondary process mainly detection plays each relevant function to the program in current demand signal source
Module, if there being functional module to be in opening, then stops the function of its correspondence, and such as, current demand signal source is ATV (simulation electricity
Depending on signal) or during DTV (digital television signal), then caption function, such as CC (Closed Caption, the U.S. can be stopped
The captions of standard) etc., currently open teletext function, also can stop this function, wherein, teletext is that television text is wide

State sound configuration, signal source reproduction ratio and the ratio mode of target signal source；Start the TV programme with described target signal source
Play each relevant function, and update channel assignment list；The locking of described target signal source is set, and judges described target
Signal source is the need of opening hbbtv service, if desired, then open the hbbtv service of described target signal source.
After the passage of target signal source is opened, test signal, proceed by sound and arrange, now sound and image
Or pent, signal is lockable, and sound and image just can be opened；Next the reproduction ratio of signal source is set, different
Signal source, the size of the picture of its display is different, as ATV analogue signal, due to the reason of interference, the matter at general edge
Amount be not fine, so fidelity factor can be little, as DTV, HDMI (High Definition Multimedia Interface,
Digitized video/audio interface technology) etc. digital signal, anti-interference meeting is relatively good, so reproduction ratio can be bigger, and PC signal
Reproduction ratio require be 100%.Next it is exactly Set scale pattern, if user have adjusted 4:3 or 16:9, switching signal
Just according to the ratio setting ratio mode of user setup after source, after being provided with, start OAD, CEC, CC, teletext, MTS
Deng service, wherein OAD is the function using DTV passage to carry out television set upgrading, and CEC is the communication between HDMI equipment, and MTS is
The detection service of beautiful sound, beautiful sound is close to instant reducing and expansion voice-frequency-multichannel broadcast.Then update channel list, play for channel
Ready work, if current demand signal source is lockable, that is last if it is desired to start the service of hbbtv, just starts
Hbbtv services.
After switching signal source is opened in real execution, as long as preserving current signal source state, even if switching signal source is complete
Becoming, the functions such as sound below is arranged, target signal source reproduction ratio, ratio mode can progressively start, and these services
All ratios are relatively time-consuming, in order to the fluency of user operates, it is possible to continue executing with on backstage.
With reference to shown in Fig. 2, for television set in prior art when carrying out the switching of signal source, complete signal switching flow
Schematic diagram, with reference to shown in Fig. 3, the method for proposing according to the present invention carries out the schematic flow sheet of the switching of signal source, the present invention
The form using multi-course concurrency carries out the switching of signal source, anything will not had to affect host process, but can ratio time-consuming
Service is put into secondary process and performs, such as, hbbtv service, reset etc. of SCART interface output, stop captions, CC,
Teletext etc. service be also as, main switching signal source is not impacted, but can ratio time-consuming, these functions
The execution time can be finished before opening signal source channels again, it is possible to concurrent execution.Through writing code
Checking, the existing television signal source time-consuming 750ms of switching, and the method using the present invention, television set switching signal source only needs
Want 200ms, greatly improve the switch speed of signal source, shorten signal source and switch the time taken.
The changing method of the signal source that the present embodiment proposes, when receiving signal source switching command, runs the first master and enters
Journey, to close current demand signal source, is run the second host process to open target signal source, is cut by current demand signal source with price television set
Shift to target signal source, and, running while the first host process, running the first secondary process and the closing current demand signal source
Multiple Process Synchronizations, therefore, when carrying out the switching of signal source, can be carried out by second mate's process, will signal source switching mistake
Journey needs each function performed be divided into multiple Process Synchronization to carry out, and host process will not be made by the operation of each secondary process
Become impact, therefore, it can concurrent synchronous operation, greatly improve the switch speed of signal source, shorten signal source switching
The time taken, the signal source switch speed solving existing television set is slow, the technical problem of holding time length.
Second embodiment of the changing method of television signal source of the present invention is proposed based on first embodiment.At the present embodiment
In, before opening the step of passage of described target signal source, the changing method of this television signal source further comprises the steps of:
When the signal of described target signal source being detected, it is judged that whether the described second secondary process has been run；
If the described second secondary process has been run, perform to open the passage of described target signal source, and preserve described mesh
The step of the current state of mark signal source；
If after the described second secondary process has been run, then time delay waits until the described second secondary process has performed, and performs
Open the passage of described target signal source, and preserve the step of the current state of described target signal source.
Owing to for different signal sources, when playing TV programme, the function of setting is not quite similar, therefore, captions,
The stopping of the service such as CC, teletext also may be not carried out complete before opening echo signal source channels, therefore, in detection
During to the signal of target signal source, to first judging whether secondary process has been run, if having run, then opening described echo signal
The passage in source, and preserve the current state of described target signal source, otherwise time delay waits until the described second secondary process has performed
Become.
The present invention also proposes a kind of television set.
