Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
With reference to Fig. 1, Fig. 1 utilizes the schematic flow sheet of first embodiment of the method for voice channel selection for the present invention, and this method may further comprise the steps among this embodiment:
S11 receives the voice command that the user imports, the lang sound of going forward side by side identification.
The voice control technology is comparatively ripe now, so do not remake detailed description at this.In specific embodiment, preferred, speech recognition is limited dictionary local voice identification, and its meaning is for discerning the voice command of user's input from fixing dictionary (dictionary that for example comprises all TV station's titles).The benefit that speech recognition is preferably limited dictionary local voice identification is: discrimination is high, because the word in the dictionary all is effective word, in case discern successfully just effectively certain; Take resource lacking very, because pointed, the word that it write down is TV station's title, and its word amount that comprises seldom, and 1000 words almost can comprise all TV station's titles; Recognition speed is fast, and local identification does not need network.Certainly the present invention is not limited to limited dictionary local voice identification, can be as required, and along with continuous advancement in technology, the speech recognition among the present invention also can be cloud identification, the present invention can expand to according to channel selections such as programm name or types like this.
S12 finds out the TV station's title through speech recognition from mapped file, the channel automatic redirect corresponding according to TV station's title.
The present invention is through finding out the TV station's title through speech recognition in mapped file; The channel automatic redirect corresponding according to TV station's title; Be that the operator can realize channel selection through TV station's title, and need not to remember the channel of target TV station, make operation more convenient; Channel selection is more accurate, and diving tower is more timely.
For example " central authorities five " corresponding in certain television set be " 22 "; In traditional non-voice channel selection television set; Remembered the operator under the situation of " five in central authorities " correspondences " 22 ", needed to select " 22 " to realize channel selection (perhaps selecting " 22 " to realize channel selection) through the button that adds deduct on the control panel through remote keying; Even if in the prior art based on also reporting the mode of " 22 " to realize channel selection through the operator only in the television set of voice channel selection.If when the operator did not know " five in central authorities " correspondence " 22 ", channel was searched for one by one.Be that non-voice channel selection television set of the prior art or voice channel selection television set all are to realize channel selection through the channel of discerning extraneous input.It is following not enough to realize that through the channel of discerning extraneous input the scheme of channel selection exists: the channel that can't remember each TV station; Even if can remember the channel of part TV station in oneself television set; But the channel of identical TV station in other television set maybe be different; So when when other sees TV, still select target TV station rapidly and accurately is when the pairing channel of target TV station can't be learnt; Need one by one channel to search for, time-consuming and shorten useful life of remote controller or guidance panel owing to the use that has increased remote controller or guidance panel.
To above-mentioned deficiency, technical scheme provided by the invention is through from mapped file, finding out the TV station's title through speech recognition, the channel automatic redirect corresponding according to TV station's title.Particularly; After extraneous input voice " five in central authorities " were identified, through searching TV station's title and the corresponding mapped file of having set up of channel, television set self converts " 22 " to " five in central authorities " can realize changing platform; Need not to remember the channel of each TV station's correspondence; It is higher to carry out the channel selection accuracy through constant TV station's title, and practicality is stronger, compatible better; And can reduce the use of remote controller or guidance panel, prolonged the useful life of remote controller or guidance panel.
With reference to Fig. 2; Fig. 2 utilizes the schematic flow sheet of second embodiment of the method for voice channel selection for the present invention; Method among this embodiment also comprised step S10 before step S11 on the basis of first embodiment: set up channel and the corresponding mapped file of TV station's title.
As everyone knows; TV station's title is constant basically; But the pairing channel of same TV station title on every television set maybe be different; Channel is corresponding with the TV station title to be according to the situation of concrete television set and definite, so the corresponding mapped file of every television set intermediate frequency Taoist monastic name and TV station title is also possible different.Can alleviate the burden that the operator remembers channel so set up channel with the TV station corresponding mapped file of title, make channel selection more convenient accurate, diving tower is more timely.
With reference to Fig. 3, Fig. 3 is the schematic flow sheet of first execution mode of setting up the channel mapped file corresponding with the TV station title among the present invention.Setting up channel in this execution mode may further comprise the steps with the TV station corresponding mapped file of title:
S21 obtains channel information when the platform operation is searched in execution, channel information comprises channel and sign picture, and with channel and the corresponding preservation of sign picture.
Known like those skilled in the art institute, new TV buy back when using or situation such as television station channel is unclear under, the platform operation is searched in execution.Search the platform operation and can be automatic channel search or manually search platform, the pairing channel of television station channel of customized justice locking when manually searching platform.No matter be automatic channel search or manually search platform, the channel information acquiring unit all will obtain the channel information that comprises channel and sign picture, and with channel and the sign picture is corresponding preserves.
In specific embodiment, when the channel information acquiring unit obtains the sign picture, preferably; The screen of the television station channel screen upper left side certain limit of the current locking of intercepting shows picture, is to obtain TV station's station symbol owing to obtain the purpose of sign picture, and follow-up being used for compares with local library file station symbol picture; And all in the upper left corner, the resolution of display screen is 1920*1080 between present TV station station symbol, therefore only needs intercepting (x:10; Y:0, w:150, h:100) image of scope.Certainly along with the picture recognition development of technology, but the whole screen of the television station channel of the current locking of intercepting, and the amount of information of whole screen is bigger, can carry out channel selection through programm name or type like this.
S22 will identify that the station symbol picture compares in picture and the local library.
Utilize existing opencv storehouse of increasing income to realize simple identification to TV station's station symbol; Be about to identify that the station symbol picture compares in picture and the local library; The likelihood of station symbol picture reaches preset value in sign picture and local library; Then be judged as identically, in follow-up processing, correspondence preserved the TV station title corresponding with this station symbol picture in corresponding channel of this sign picture and the local library; Do not reach preset value, then do not handle.In specific embodiment,, preferably this preset value is taken as 90% in order to guarantee high discrimination and accuracy.
S23 when the likelihood of comparing result reaches preset value, then will identify in corresponding channel of picture and the local library TV station name group corresponding with the station symbol picture and build up mapped file.
Be described in detail below in conjunction with the establishment of an instance to mapped file shown in Figure 3, as shown in Figure 4, the concrete steps of the establishment of mapped file are:
S31, manual or automatic channel search.
S32 judges whether to have locked television station channel; If do not have locking television platform channel, then turn back to step S31; If locked television station channel, then continue step S33.
S33, the picture in the intercepting TV screen in the certain limit of the upper left corner be as the sign picture, and with current channel number and sign picture corresponding stored.
S34 judges whether to search platform and finishes; Do not finish if search platform, then turn back to step S31; Finish if search platform, then continue step S35.
S35, with the storage the sign picture one by one with local library in the station symbol picture compare.
S36 judges whether the likelihood of comparing result reaches 90%; If do not reach 90%, then turn back to step S35 and proceed contrast; If reach 90%, then continue step S37.
S37, the TV station name group corresponding with the station symbol picture built up mapped file in channel that the sign picture is corresponding and the local library.
S38 judges whether all sign pictures contrast and finish; If contrast does not finish, then turn back to step S35 and proceed contrast; If contrast finishes, then finish, promptly accomplished the establishment of mapped file.
In practical operation; Possibly appear at redirect failure automatically among the step S12; The reason that automatic redirect failure among the step S12 occurs has many-side; Like speech recognition unsuccessful (deviation feasible value when the operator exists accent or dialect to surpass when reporting to make speech recognition), image recognition unsuccessful (not have to store the station symbol picture corresponding in the local library file) etc. with the sign picture of target channel.
