Abstract
Belonging to technique of TV set, the invention includes steps: create structure of channel, including operation for setting up volume control function for each channel to output balanced volume for each channel; setting up general volume control variable Vol in order to control magnitude of volume of all channel; making range of channel volume control Channel audio be from minus half to positive half of general volume control in order to guarantee that channel volume control is only in use for balancing output volume for each channel; weighted synthesis is adopted between channel volume control and general volume control; outputting synthesized volume. When signal is weak, the circuit setup in the invention is cut off automatically in order to eliminate noise of weak signal. The invention outputs balanced volume for each channel, and reserves general volume control for user to control magnitude of volume of all channel. Features are: simple adjustment.
Description
Technical field
The invention belongs to technical field of television sets, more particularly relate to the design of the synthetic method for controlling volume of control of channel volume and the control of general volume.
Background technology
The traditional method for controlling volume of television set is to regulate volume, guarantees that the user can be with the suitable volume TV reception.And the adjusting of volume can be finished by the volume control pin of main control microprocessor control audio processor.
This control to the audio frequency amplifier section is all carried out simultaneously to all channels, makes no exception.But the audio volume of each TV station has nothing in common with each other.The volume of each channel is widely different when therefore, watching.For the sound accompaniment of suitable size is arranged, the spectator must regulate volume one by one once more when changing channel, quite trouble.That is to say that traditional volume control mode can't be accomplished the volume output of each channel equalisation.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and a kind of channel volume control and the synthetic method for controlling volume of general volume control are provided.It can accomplish the volume output of each channel equalisation.Both used the control of channel volume, to guarantee the equilibrium of each channel volume output; Keep general volume control again, to solve the problem that the user need control the volume of all channels simultaneously.Its adjusted is very simple.
In order to achieve the above object, the present invention includes following steps:
(1) creates the channel structure, each channel is provided with volume control circuit separately, make each channel volume output balanced;
(2) general volume control Vol global variable is set, to control the volume of all channels simultaneously;
(3) scope of channel volume control Channelaudio be general volume control range Vol positive and negative half, that is the scope of channel volume control be general volume control negative half to just half, guarantee that the control of channel volume just is used for the equilibrium of each channel volume output;
(4) adopt the weighted mode synthetic control of channel volume and general volume control;
(5) output of the volume after will synthesizing.
Quiet control is still realized by general volume control circuit.
Function of automatically cutting off when the present invention also is provided with weak signal is to eliminate the weak signal noise.
Task of the present invention comes to this and finishes.
The invention provides a kind of channel volume control and the synthetic method for controlling volume of general volume control.It can accomplish the volume output of each channel equalisation.Both used the control of channel volume, to guarantee the equilibrium of each channel volume output; Keep general volume control again, to solve the problem that the user need control the volume of all channels simultaneously.Its adjusted is very simple.It can be widely used in the various television sets.

Fig. 2 is the synthetic flow chart of its volume.
Embodiment
Embodiment 1.Control of a kind of channel volume and the synthetic method for controlling volume of general volume control are as Fig. 1～shown in Figure 2.
It may further comprise the steps:
(1) creates the channel structure, each channel is provided with volume control Channelaudio circuit separately, make each channel volume output balanced;
(2) general volume control Vol circuit is set, to control the volume of all channels simultaneously;
(3) make the scope of channel volume control Channelaudio be general volume control Vol positive and negative half, that is the scope of channel volume control Channelaudio be general volume control Vol negative half to just half, guarantee that channel volume control Channelaudio just is used for the equilibrium of each channel volume output;
(4) adopt the weighted mode synthetic channel volume control Channelaudio and general volume control Vol;
(5) output of the volume after will synthesizing.
In the present embodiment, the initial value of general volume is half of max volume, that is Vmax/2, and the initial value of channel volume is 10% of a max volume.When the user determines the sound accompaniment of certain is Tvol, and then channel volume control Channelaudio is Tvol-Vmax/2.After accomplishing the setting up, after this during switching channels, volume output be Vol+Channelaudio just, and this is the result after synthesizing.Simultaneously, when the value of Channelaudio+Vol was excessive or too small, being provided with in volume had maximum to judge to guarantee that output can not make mistakes in the function.
Quiet control is still realized by general volume control circuit.
Function of automatically cutting off when present embodiment also is provided with weak signal is to eliminate the weak signal noise, as rustle or the like.
The source code of present embodiment is as follows:
Embodiment 1 had both used the control of channel volume, to guarantee the equilibrium of each channel volume output; Keep the control of general volume again,, need volume with all channels all transfer to when very little as televiewing midnight to solve the problem that the user need control the volume of all channels simultaneously.Its adjusted is very simple.It can be widely used in the various television sets.
Claims (3)
1. a channel volume control is controlled synthetic method for controlling volume with general volume, it is characterized in that may further comprise the steps:
