Description
Technical field
The present invention relates to TV technology, specifically, relate to the technical field of television sound volume control.
Background technology
Development along with TV tech and related industry, TV programme is more and more abundanter, the channel that TV can be watched is more and more, is a problem that allows the user not feel well but carry out the TV sound disunity that each channel sends when switching under same volume index.
When the user switches to a channel, the user will adjust accordingly to image and sound in watching the process of this channel, image harmony sound is adjusted to the optimum state that is fit to oneself, if the user switches to other channel, often certain variation can appear in the sound of TV, and relatively suitable volume will be excessive or too small.This is to be caused by following reason: what the transmission of sound accompaniment was adopted is mode of frequency regulation, the modulation degree difference of each TV station, the sound amplitude difference that causes receiving terminal (as television set) demodulation to be come out, thus the sound size of sending under identical volume index is variant.
Thereby behind user's switching channels, the user needs the frequent adjustment suitable volume to reach oneself satisfied sound.For addressing the above problem, some TV production firm increases the mode of secondary volume by give each channel in menu at present, the volume that the volume (master volume) that user tradition is regulated and the secondary volume of current channel are carried out after the particular procedure is sent into the Audio Processing chip, and the sound of each channel output is consistent substantially.Each channel all has independent secondary volume to regulate, and the information of secondary volume and this TV station leaves in the holder together.The volume of each channel determines jointly by master volume and secondary volume, and the user only changes the size of current channel volume when regulating secondary volume, and to other channels without any change; And the user can cause variation to all channel volumes when regulating master volume.If the user finds that the sound of a certain channel is excessive, will deal with problems by adjusting to secondary volume, when switching to another channel, owing to can not influence master volume to the adjustment of secondary volume, therefore the master volume of new channel still is the master volume of a last channel.
Adopt said method to solve the user to a certain extent and change frequent problem of regulating volume behind the platform, but this method is when concrete the application, normally with secondary volume as a Submenu Items under the main menu, need the user to enter the secondary volume that the corresponding entry in the menu could be regulated this channel when regulating, operate more loaded down with trivial detailsly, cause the user after changing platform, to regulate master volume so that sound is of moderate size.Therefore, be necessary to invent a kind of method that meets user operation habits, make the user can regulate master volume, secondary volume fast.
Summary of the invention
The object of the present invention is to provide a kind of method of balancing volume of TV channels, regulate loaded down with trivial details problem to solve the radiovisor volume that has the major-minor volume in the prior art.
For achieving the above object, the technical solution used in the present invention is as follows: a kind of method of balancing volume of TV channels, and described method comprises following step:
Judge after the volume regulating command of a, MCU reception user input whether the TV current channel is first channel of start back, if, think directly that then the user need adjust master volume, otherwise judge that this volume regulates whether in recognition time, if, think that then the user need adjust the secondary volume of TV, otherwise think that the user need adjust master volume that described recognition time is the value of system default or the value that the user sets; Wherein, described master volume and secondary volume determine the volume of each channel jointly, and change the size of current channel volume when adjusting secondary volume, and other channel volume changes not, change current channel volume and other channel volume when adjusting master volume simultaneously;
If b thinks that the user need adjust master volume, then the TV master volume is adjusted according to user instruction, if think that the user need adjust secondary volume, then the secondary volume of TV is adjusted according to user instruction.
Wherein step b specifically comprises:
If b1 thinks that the user need adjust master volume, described MCU according to described sound volume regulating command the TV master volume is adjusted, if think that the user need adjust secondary volume, described MCU adjusts the secondary volume of TV according to described volume regulating command.
Wherein step b1 also comprises:
If think that the user need adjust master volume, described MCU control master volume is adjusted menu and is shown on video screen, if think that the user need adjust secondary volume, described MCU controls secondary volume adjustment menu and shows on video screen.
Corresponding label character was MAIN VOLUME when wherein said master volume adjustment menu showed on video screen, and corresponding label character was SUB VOLUME when described secondary volume adjustment menu showed on video screen.
The present invention overcomes the deficiencies in the prior art, employing receives what at first judge that the user need adjust behind the volume conditioning signal of user's input at television set be master volume or secondary volume, show that according to judged result master volume is adjusted menu or secondary volume is adjusted the technical scheme that menu is adjusted for the user on screen then, make the user when switching TV channel, can adjust master volume or secondary volume as required fast, the volume of radiovisor is regulated operation more fast, conveniently, has improved the efficient of TV watching.
Description of drawings
Fig. 1 is for supporting that the present invention regulates the Principles of Television schematic diagram of volume;
Fig. 2 is an embodiment of the invention flow chart.
Embodiment
As shown in Figure 1, the system that implements on simulated television of the described technical scheme of present embodiment comprises that mainly MCU, tuner, memory, remote control receiving unit, master/secondary volume regulate judging treatmenting module, image processing circuit, sound treatment circuit and sound and image output.
Wherein, the remote control receiving unit receives the control signal of user by the remote controller input, MCU carries out channel switching, image harmony tone joint according to this control signal, send the output of image and sound output after image and sound treatment circuit are handled to the received signal accordingly.
Wherein, in the memory except depositing the master volume data, also deposit the corresponding secondary volume data of each channel and each channel, behind the each switching channels of user, system obtains the secondary volume of this channel according to channel from memory (as EEPROM), send into the acoustic processing module with the master volume data, carry out realizing the balance of voice output with the computing of master volume.
Technical solution of the present invention has increased master/secondary volume and has regulated judging treatmenting module, and this module is to need to regulate master volume or regulate secondary volume by the judgement volume adjusting this time of present system status and user operation habits intelligence.If judged result is for regulating master volume, then the master volume menu is presented on the screen, regulates master volume and carries out voice output after the acoustic processing; If judged result is for regulating secondary volume, then secondary volume menu is presented on the screen, regulates secondary volume and carries out voice output after the acoustic processing.When the volume menu showed, the user can be by manually leading by button specific on the remote controller (this button can be provided with separately also can multiplexing other existing buttons)/switching that secondary volume is regulated.
Consult flow process shown in Figure 2, after the user sends the volume adjusting command by remote controller, in step 21, judge that at first whether current watched channel is first channel (step 21 can realize with the mode that step 22 directly is set to No) after the start.Because common operating habit according to people, often earlier volume is adjusted after user's start, treat that volume adjusts to the program of selecting whether to watch this channel after the desired value again, otherwise start just carries out directly that channel selection will cause too loudly can be very noisy, the perhaps too for a short time influence judgement of can not hear clearly of sound.
So, carry out voice output after the acoustic processing if first channel after the start is directly regulated master volume by step 24.
If in step 21, system judges that current channel is not first channel after the start, illustrate that the user switched channel, and what at this moment need detailed judgement user adjusting is master volume or secondary volume.The foundation of judging is, first channel after the start illustrates that the user has configured the sound size of current needs.Step 22, judgement is from changing platform, if in recognition time, illustrates that the user is is that benchmark is regulated with previous sound size, at this moment need execution in step 23 to be used to regulate secondary volume, keep making under the constant situation of master volume the sound of this channel consistent with the previous sound size of setting; If not in recognition time, illustrate that the user sees this channel after a period of time, need again the sound size to be set, need carry out the operation that step 24 is regulated master volume by this thinking.Above-mentioned recognition time can be a numerical value of system default, also can be set up on their own by the user.
Below specify:
20, the volume regulating command that the user imports is received by system;
21, system judge whether be the start after first channel? if change step 24, otherwise change step 22;
22, system judges that user this this adjusts the time of volume whether in recognition time, if change step 23, otherwise change step 24;
23, system shows that secondary volume menu supplies the user to adjust secondary volume;
24, system shows that the master volume menu supplies the user to adjust master volume;
25, acoustic processing module is handled sound according to adjusted volume;
26, voice output output sound.
Above-mentioned way is the conclusion that draws according to people's inertial thinking and operator scheme.If crossed in the recognition time, system will control automatically from secondary volume and switch to the master volume adjusting, and show corresponding volume adjusting menu on screen.
When system adjusts menu or secondary volume adjustment menu according to above-mentioned judgment result displays master volume, if volume pattern that the user need adjust and nonsystematic are according to the volume pattern of judgment result displays, automatically show master volume adjustment menu as system according to judged result, but the user may need to adjust secondary volume under specific situation, perhaps there is situation in contrast, at this moment, therefore switching or the switching from secondary volume to master volume that the user may need active operation control to regulate to secondary volume from master volume are necessary to offer a kind of method that can switch of user between master volume and secondary volume adjustment modes.
The user initiatively selects the adjusting of major-minor volume for convenience, and a switch key can be set on remote controller, and this button can be that independent key also can be multiplexing key.Multiplexing key is only just used as switch key when the volume menu occurring; Separately the button of definition can change between master volume/secondary volume and not necessarily will switch when the volume menu occurring just effectively according to current system mode.
Wherein, volume menu character shows can not be as past " volume " commonly used (Volume), and must allow the user can be clear and definite what find out current adjusting is master volume or secondary volume, the character of volume menu can be shown and change " master volume " (Main Volume), " secondary volume " (Sub Volume) into. the user is switched master volume, use same menu when secondary volume is regulated, and only needs to change that character shows, refreshes progress bar or the numeral demonstration gets final product.
It is for reference that the wherein secondary volume identification timer time of overflowing such as can be set to 3 seconds, 5 seconds, 10 seconds at option.
