Description
[technical field]
Television set of the present invention is developed and application, relates in particular to a kind of identification method to set up of television sound standard.
[background technology]
The television sound standard mainly comprises DK standard, BG standard, I standard, M standard and L/L ' standard at present, and the sound standard in country variant and area has different, and also there is different sound standards the different regions of the same country that has.Such as, the interior ground of China is the DK standard substantially, Guangdong one band then has the signal of a lot of I standards.When the user does not know which kind of sound standard local signal is, perhaps do not understand television set, when not knowing that what is the sound standard, might mistake be set yet the sound standard of TV signal, thereby cause the sound input of television set unusual, can't normally watch.At present, the identification setting that solves the television sound standard mainly contains two kinds of methods: a kind of method is that television set is defaulted as the sound standard and discerns automatically, when the user carried out automatic channel search, program can identify the sound standard of current demand signal in searching the platform process, and stores.As the channel search method of No. 200610070037.7 disclosed automatic identification S-SYSTEM of Chinese patent application and sound standard, this method can solve the identification problem of most sound standard, but also has some limitation.For the area of some signal more complicated, nonstandard signal is more, this automatic identification procedure be easy to the sound standard identification error of signal or identification less than, cause consumer's signal that can not normally teleview; The method only just can be discerned the sound standard in automatic channel search automatically in addition, if searching the sound standard of wanting to discern again individual signal after platform finishes, then must search platform again, brings a lot of inconveniences to the user.Another kind method is before television set dispatches from the factory, according to the signal type of television set sales territory, with the default setting that dispatch from the factory of its sound standard as the sound standard of television set.But for the skimble-scamble area of sound standard, need the user manually to go to regulate, do not know the user under the situation of local sound standard, might mistake be set, influence the sound quality of TV the sound standard
[summary of the invention]
For addressing the above problem, main purpose of the present invention is to provide a kind of identification method to set up of television sound standard.
For achieving the above object, technical scheme of the present invention is:
A kind of identification method to set up of television sound standard comprises the steps:
In the sound standard, increase an options AUTO who becomes coordination with four kinds of sound standards of television set, make the sound standard of TV comprise five kinds of AUTO, DK, BG, I, M;
During automatic channel search, if after current sound standard is set to AUTO, in searching the process of platform, understand, and store according to the sound standard that identifies according to the automatic automatic sound recognition standard of determining program; Otherwise if when current sound standard is set to other four kinds of sound standards, program can be closed automatic identification procedure in the process of automatic channel search, according to user's setting, forces the sound standard of signalization, and stores according to compulsory sound standard;
After automatic channel search finishes, manual switchover sound standard is to AUTO, program can to but preceding signal is done once identification automatically, judge the sound standard of current signal, and store according to the sound standard that identifies, need not to carry out automatic channel search again can discern once more.
Compared to prior art, the identification method to set up of television sound standard of the present invention increases a new options AUTO (automatically) in the sound standard, the circulation that the user can carry out AUTO-＞DK-＞BG-＞I-＞M sound standard in the menu option the inside of sound standard is switched, the automatic identification of sound standard and pressure setting are incorporated into together, the signal that can be fit to the alternative sounds standard in different areas, adapt to different user crowds, reduced the trouble that the user regulates, be user-friendly to.
[description of drawings]
Fig. 1 is the flow process diagram of the identification method to set up of sound standard of the present invention.
[embodiment]
The identification method to set up of a kind of television sound standard of the present invention increases a new options AUTO (automatically) in the sound standard, be that the sound standard of TV comprises five kinds of AUTO, DK, BG, I, M, wherein AUTO and other four kinds of sound standards are coordination, and the circulation that the user can carry out AUTO-＞DK-＞BG-＞I-＞M sound standard in the menu option the inside of sound standard is switched.In eeprom memory all two memory addresss of overabsorption of each channel, one is the flag bit FLAG of AUTO, store the value of the FLAG of each channel, FLAG=0 represents that the sound standard of this channel is not AUTO, and FALG=1 represents that the sound standard of this channel is AUTO.Another is the memory address of sound standard, and storage will write the value SND_SYS of the sound standard of register, as SND_SYS=DK.When the current sound standard of user is set to AUTO and carries out automatic channel search, can be in searching the process of platform according to the automatic automatic sound recognition standard of determining program, and store according to the sound standard that identifies, but the sound standard option of each shows in the menu all is AUTO; When the current sound standard of user is set to other four kinds of sound standards, program can be closed automatic identification procedure in the process of automatic channel search, setting according to the user, force the sound standard of signalization, and store according to compulsory sound standard, what the sound standard option of each showed in this moment menu is compulsory sound standard.In the time of automatic channel search no longer, user's manual switchover sound standard, when switching to AUTO, program can to but preceding signal is done once identification automatically, judge the sound standard of current signal, and store according to the sound standard that identifies.Thereby identification and compulsory right to choose have been given the user automatically, area for many sound standard, even the user does not understand local which kind of sound standard that is, but as long as it is set to AUTO, search the time sound standard identification error that can take place once in a while of platform for nonstandard signal, after platform finishes individual other signal is switched to AUTO again with the sound standard as long as search, need not to carry out automatic channel search again can discern once more.
See also shown in Figure 1ly, in needs indicated channel sound standard, program can be read the value of the FLAG among the EEPROM, if FLAG be 1 then be shown as AUTO, otherwise be shown as the storing value SND_SYS (such as DK) of sound standard.When the user carries out the operation of automatic channel search, program can judge that the preset value of sound standard is AUTO, if during AUTO, program can be after each channel searches out signal, operation automatic sound identification module, sound standard to this signal is discerned automatically, and the sound standard (SND_SYS) after the identification stores among the EEPROM, simultaneously the value of FLAG is made as 1, store EEPROM into, frequency up to search withdraws from the platform program of searching greater than 863MHz or when artificially ending, it all is AUTO, the i.e. FLAG=1 of each searched channel that arrives that the sound standard of the channel of all search this moment shows.If judge that the preset value of sound standard is AUTO, then program can be closed the sound automatic identification procedure when automatic channel search, after each channel searches out signal, the force values SND_SYS (such as SND_SYS=DK) of sound standard can be written among the EEPROM, simultaneously FLAG=0 is write among the EEPROM, up to the frequency of search greater than 863MHz or think and withdraw from the platform program of searching when ending, it all is compulsory value (such as DK) that the sound standard of the channel of all search this moment shows, the FLAG=0 of each searched channel that arrives.When in user's manual switchover sound standard the time, because after switching, the sound standard SND_SYS that stores among the EEPROM changes, so when switching to AUTO, do once identification automatically again.
The user regulates in menu in the sound standard option value, program can judge whether the sound standard after the user regulates is AUTO, if AUTO, program can be called the automatic identification module of sound, current signal is carried out sound again to be discerned automatically, and the sound standard SND_SYS after the identification is written in the register, simultaneously the sound standard and the FLAG=1 that recognize are stored among the EEPROM.If not AUTO, the sound standard SND_SYS (such as SND_SYS=DK) after then program can be regulated the user directly writes to register and EEPROM, and FLAG=0 is write EEPROM.And the user changes platform when operation, program can be read the value of the FLAG of corresponding channel among the EEPROM, if FLAG is 1, then the sound standard is shown as AUTO, if FLAG is 0, the sound standard is shown as storing value SND_SYS (such as DK), simultaneously the storing value SND_SYS of sound standard is write in the register.
In the present invention creation, AUTO and DK/BG/I/M are relations arranged side by side, do not have priority, so before automatic channel search, have only as the user to be manually switched to AUTO, just can move the sound automatic identification procedure when searching platform, force the sound standard otherwise be equal to.This creation is the automatic identification of sound standard and force setting to be incorporated into together, the signal that can be fit to the alternative sounds standard in different areas, adapt to different user crowds, for the user who does not know the signal sound standard, the sound standard can be shown as AUTO, reduced the trouble that the user regulates, be user-friendly to.
Most preferred embodiment described above only is that the present invention is set forth and illustrates, but is not limited to disclosed any concrete form, and it is possible carrying out many modifications and variations.
