Abstract
The invention discloses a signal processing system, comprising a channel mode discriminator, used for determining current sound of a sound signal; a regulator, used for determining that the output sound signal satisfies a preset condition and regulating the sound signal for a preset amount; a detector, used for detecting the amplitude of the sound signal; a controller, used for converting the drive of a checker according to the amplitude of the sound signal; and a determiner, used for determining whether the sound signal satisfies the preset condition according to the controller. According to the signal processing system disclosed by the invention, the channel mode discriminator is used for regulating the sound in a multichannel mode, so different sound can be controlled to obtain a better audio-visual effect.
Description
Technical field
The present invention relates to a kind of signal processing system.
Background technology
Television broadcasting signal includes the Voice & Video composition separated, i.e. acoustical signal and video signal.Acoustical signal includes audio system identification data, and it informs reception system for the emission parameter of such as sound carrier frequency.Known muli-sounds playing device has by suppressing output volume to regulate the function of output sound, in existing audio signal processor, the usually broadcast singal of single channel model, controller continues to check the conversion whether broadcasting sound signal carries out one of stereo/dual channel mode, the operation of inspection continuously performed for this order of acoustic pattern conversion produces less desirable audio artifacts, reduces the sound quality adopting Sound Processor Unit.
Therefore, for solving the problems referred to above, a kind of new technical scheme of special offer.
Summary of the invention
The present invention provides a kind of signal processing system.
The technical solution used in the present invention is:
A kind of signal processing system, including:
Channel pattern descriminator, it is for determining the current sound of acoustical signal；
Actuator, it is for determining that the acoustical signal exported meets predetermined condition and is adjusted scheduled volume；
Controller, it for carrying out the driving of transition checker according to the amplitude of acoustical signal；
Determiner, according to controller, it is for determining whether acoustical signal meets predetermined condition；
Detector, it is for detecting the amplitude of acoustical signal.
Further, described channel pattern descriminator provides the acoustical signal of multiple sound channels.
Further, described determiner changes the level of each acoustical signal of device output based on multiple level, determining whether the general trend of the acoustical signal of multiple sound channel meets predetermined condition, described actuator updates level adjustment information, and peak value and average that described amplitude is based on sound are certain.
The invention has the beneficial effects as follows: adopt channel pattern descriminator to carry out the mode of multichannel, sound is adjusted, different sound can be controlled, it is thus achieved that audio visual effect preferably.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the structural representation of the present invention.
Wherein: 1, channel pattern descriminator, 2, actuator, 3, determiner, 4, detector, 5, controller, 6, level changes device.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment is only used for explaining the present invention, is not intended that the restriction to protection scope of the present invention.
As it is shown in figure 1, a kind of signal processing system of the present invention, including:
Channel pattern descriminator 1, it is for determining the current sound of acoustical signal, and channel pattern descriminator provides the acoustical signal of multiple sound channels；
Actuator 2, it is for determining that the acoustical signal exported meets predetermined condition and is adjusted scheduled volume, and actuator 2 updates level adjustment information；
Controller 5, it for carrying out the driving of transition checker according to the amplitude of acoustical signal, and peak value and average that amplitude is based on sound are certain；
Determiner 3, according to controller 5, it is for determining whether acoustical signal meets predetermined condition, it is determined that device 3 changes the level of each acoustical signal of device 6 output based on multiple level, it is determined that whether the general trend of the acoustical signal of multiple sound channels meets predetermined condition；
Detector 4, it is for detecting the amplitude of acoustical signal.
The invention has the beneficial effects as follows: adopt channel pattern descriminator to carry out the mode of multichannel, sound is adjusted, different sound can be controlled, it is thus achieved that audio visual effect preferably.
The above, be only presently preferred embodiments of the present invention, is not the restriction that the present invention makees any other form, and any amendment that the technical spirit of the foundation present invention is made or equivalent variations, still fall within present invention scope required for protection.
