Abstract
The invention discloses a method to realize sound volume offset in TV channel. Wherein, solidifying opposite program in MCU, setting opposite menu on function sub-menu, arranging space to storemultigrade discrete distributed sound volume offset in EEPROM. Then, it should execute following steps: 1) selecting sound volume offset menu; 2) selecting overlay value; 3) storing offset value in EEPROM, writing and overlayed value in register controlled by MCU to update current volume; 4) judging whethar user show OK, if yes, completing; or else, repeating step 1). This method can adjust the sound volume precisely.
Description
Technical field
The present invention relates to be used in the television system receiver circuit parts of sound signal, especially relate to a kind of method that realizes audio volume offset at each channel of TV set.
Background technology
The transmitted power size of existing each TV station there are differences, the transmitted power size of the different channel of same TV station also there are differences, after causing the user in the TV reception process, to carry out the channel transposing, the sound signal power of the power amplification circuit output of television audio signal processing system can change, television audio is become greatly or suddenly suddenly to diminish, influence auditory effect, the user wants manual adjustment television audio output volume, the volume of respectively overlapping TV programme is reached unanimity substantially, and televiewing to the user makes troubles.Some television set has the function of automatic volume control on the market, mainly is the hearing of restriction max volume with the protection user, and adjustable range is limited and owe accurate, can't promote when volume is too small.
Summary of the invention
Technical problem to be solved by this invention is to remedy existing defective, proposes a kind of method at each channel of TV set realization audio volume offset, and this method can accurately be regulated the sound accompaniment output volume on a large scale.
Technical problem of the present invention is solved like this:
Thisly realize the method for audio volume offset at each channel of TV set, comprise the Menu key that is separately positioned on remote controller and/or the TV set panel, program △/ key, volume+/-key, and solidify corresponding program at the microcontroller MCU of television set.
Thisly realize that at each channel of TV set the characteristics of the method for audio volume offset are:
Sound at television set preliminary election function submenu divides setting " audio volume offset " option in the menu;
In electro erasible programmable preface read-only memory EEPROM, be provided with the corresponding space of the audio volume offset value that is used to deposit the multistage discrete distribution of each channel;
The corresponding program of described curing is the audio volume offset program, carries out following steps successively at each channel of TV set:
1) current channel audio volume discomfort is felt in user's sense of hearing, pushes described Menu key from normal pictures, and the sound that enters television set preliminary election function submenu divides in the menu, pushes described program △/ key again and selects " audio volume offset " option;
2) selective stacking audio volume offset value, if user's sense of hearing feels that the current channel audio volume is bigger than normal, just pushing described volume-key changes, MCU receives the instruction of " audio volume-", and certain one-level audio volume negative bias that the corresponding stack of output of MCU control audio signal treatment system is stored in EEPROM moves value; If user's sense of hearing feels that the current channel audio volume is less than normal, just push described volume+key and change, MCU receives the instruction of " audio volume+";
3) by software control offset value is stored in the EEPROM, and will be worth with master volume stack after the audio volume value write in the register of MCU control volume, refresh the current channel audio volume;
Is 4) user satisfied with to current channel audio volume offset value? if the audio volume offset program is finished, if not, repeating step 1).
Technical problem of the present invention can be to solve according to qualifications like this:
The audio volume negative bias of described multistage discrete distribution move value, acquiescence value, positive offset value be-20 ,-19 ...-1,0 (default value) ,+1 ... + 19 ,+20, adjusting the step-length position is 1, to realize accurately regulating the sound accompaniment output volume on a large scale, even the current channel audio volume is too small, also can be promoted.
The inventive method has increased the added value of television set based on solidifying corresponding program with microcontroller as the television set of main control chip with at microcontroller, have novel, the operation interface close friend, method is simple, and is easy to use, the characteristics of reliable in function.The present invention is as long as push the corresponding function key on remote controller and/or TV set panel, activate each channel audio volume offset function, just can be according to the sound signal power of the concrete output of every cover TV programme, select the audio volume offset value of each channel voluntarily by the user, the audio volume that can accurately regulate each channel on a large scale equates substantially, prevents that phenomenon big or that diminish appears becoming suddenly in television audio in channel transposing process.
Description of drawings
Below the contrast accompanying drawing and in conjunction with embodiment the present invention is further detailed explanation:
Accompanying drawing is the audio volume offset program circuit schematic diagram of an embodiment of the present invention.
Embodiment
A kind of method that realizes audio volume offset at all 256 channels of television set
This method comprise the Menu key that is separately positioned on remote controller and/or the TV set panel, program △/ key, volume+/-key, sound at television set preliminary election function submenu divides setting " audio volume offset " option in the menu, and solidify the audio volume offset program in TV MCU, in EEPROM, be provided with the corresponding space of the audio volume offset value that is used to deposit the multistage discrete distribution of each channel.Described MCU is that model is the MCU of Philips UOC III, and described EEPROM is that model is the EEPROM of Atmel AT24C16.
As shown in drawings, carry out following steps successively at each channel of TV set:
1) current channel audio volume discomfort is felt in user's sense of hearing, pushes described Menu key from normal pictures, and the sound that enters television set preliminary election function submenu divides in the menu, pushes described program △/ key again and selects " audio volume offset " option;
2) selective stacking audio volume offset value, if user's sense of hearing feels that the current channel audio volume is bigger than normal, just pushing described volume-key changes, MCU receives the instruction of " audio volume-", and certain one-level audio volume negative bias that the corresponding stack of output of MCU control audio signal treatment system is stored in EEPROM moves value; If user's sense of hearing feels that the current channel audio volume is less than normal, just push described volume+key and change, MCU receives the instruction of " audio volume+";
3) by software control offset value is stored in the EEPROM, and will be worth with master volume stack after the audio volume value write in the register of MCU control volume, refresh the current channel audio volume;
Is 4) user satisfied with to current channel audio volume offset value? if the audio volume offset program is finished, if not, repeating step 1).
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the present invention is determined by claims of being submitted to.
