Abstract
The invention discloses a method for processing image sound. A receiving module, a sound signal distinguishing module, a storage module and a signal processing module are included; an image sound signal is received by utilizing the receiving module; the received image sound signal is analyzed and judged by utilizing the sound signal distinguishing module, such that a sound source is distinguished out; and a noise signal in the sound signal distinguishing module is eliminated by utilizing the signal processing module, such that the signal is transmitted into the storage module to store. The method disclosed by the invention has the benefits that: the image sound signal is processed by adopting the sound signal distinguishing module; the sound noise is eliminated; sound can be stored and displayed; and the method accords with the humanized operation trend and is convenient.
Description
Technical field
The present invention relates to a kind of method processing video/audio.
Background technology
Have developed many sound signal processing technology, attempted to improve the quality of the sound using loudspeaker reproduction in the acoustic system, especially for the sound system comprising the stereo channels be made up of left and right acoustic channels parts.The example of such sound system is home audio system, such as hi-fi system, cinema sound systems and automobile sound systems, their equal processing audio signal, to provide audio input signal for loud speaker.But existing loud speaker has some noises in voiced process, the mode of general removal noise adopts filter, via filter circuit, to voltage signal also or current signal process, this kind of filter is all be input in circuit by all signals, and the voltage of recycling signal also or the amplitude of electric current, frequency characteristic, and tells noise and required signal, utilize this kind of mode cannot receive all signals, can not process all signals.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The invention provides a kind of method processing video/audio.
The technical solution used in the present invention is:
Process a method for video/audio, comprise receiver module, distinguish sound signal module, memory module and signal processing module,
A receiver module is utilized to receive video/audio signal;
Sound signal module is analyzed to received video/audio signal, is judged to utilize one to distinguish, to pick out sounding source of sound;
Utilize a signal processing module to remove and distinguish noise signal in sound signal module, signal is sent in memory module and stores.
Further, described memory module utilizes control unit to be stored by video/audio signal.
Further, described in distinguish that sound signal module is by the different qualities of different signal, and received sound signal carried out respectively and judge, utilizing the different phase place of sound signal, and tell source signal.
Further, distinguish described in that the signal after sound signal resume module sound is presented on display module.
Further, described display module is connected to coder-decoder.
The invention has the beneficial effects as follows: adopt and distinguish that sound signal module processes video/audio signal, eliminate the impurity of sound, can store sound and show, meet the operation trend of hommization, convenient.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, receiver module, 2, distinguish sound signal module, 3, memory module, 4, signal processing module, 5, display module, 6, coder-decoder, 7, control unit.
Embodiment
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, only for explaining the present invention, does not form the restriction to protection scope of the present invention.
As shown in Figure 1, a kind of method processing video/audio of the present invention, comprises receiver module 1, distinguishes sound signal module 2, memory module 3 and signal processing module 4,
A receiver module 1 is utilized to receive video/audio signal;
Sound signal module 2 is analyzed to received video/audio signal, is judged to utilize one to distinguish, to pick out sounding source of sound, distinguish that sound signal module 2 is by the different qualities of different signal, and received sound signal is carried out respectively and judges, utilize the different phase place of sound signal, and tell source signal, distinguish sound signal module 2 process sound after signal be presented on display module 5, display module 5 is connected to coder-decoder 6;
Utilize a signal processing module 4 to remove and distinguish noise signal in sound signal module 2, be sent to by signal in memory module 3 and store, memory module 3 utilizes control unit 7 to be stored by video/audio signal.
The invention has the beneficial effects as follows: adopt and distinguish that sound signal module processes video/audio signal, eliminate the impurity of sound, can store sound and show, meet the operation trend of hommization, convenient.
The above is only preferred embodiment of the present invention, is not restriction the present invention being made to any other form, and any amendment done according to technical spirit of the present invention or equivalent variations, still belong to the present invention's scope required for protection.
