Abstract
The invention provides an audio/video acquisition method. An input audio/video signal is received and converted into a computer file, and the computer file is stored in a storage; and the method comprises the following steps of: acquiring video and audio data and storing files according to different formats. For a user, the audio/video acquisition method has the advantages of improving the acquisition efficiency, simplifying the operating difficulty and providing convenient use, in particular achieving high intuition by increasing dynamic video.
Description
Technical field
The present invention relates to sound signal and video signal collective field, particularly in Digital Television computer receiving trap, finish the method for sound signal and video signal collective by a button.
Background technology
Current, image collecting device, can by USB interface with have the equipment of display screen such as computer etc. and communicate, and the picture signal that receives is stored as image file, on the display screen of computer etc., play.Existing image collecting device has button, but keypress function is just gathered still image, can not gather dynamic image, more can not gather the beginning of dynamic image and stops.The drive software of existing product can only receive single-frame images from USB interface, and software also can only be handled the dump of single-frame images, can't compress storage to continuous, live image, it is low to cause the user to gather the dynamic image operating efficiency, and inconvenience is not directly perceived.
Summary of the invention
Have button in order to overcome existing image collecting device, but keypress function is just gathered still image, can not gather dynamic image, more can not gather the beginning of dynamic image and stop.The drive software of existing product, can only receive single-frame images from USB interface, and software also can only be handled the dump of single-frame images, can't to continuous, live image compress storage to cause the user to gather the dynamic image operating efficiency low, inconvenient, defective intuitively not the invention provides the method that a kind of digital television signal that only uses a button to finish is gathered.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of audio frequency and video acquisition method, and receive the AV signal of input, and convert AV signal to computer document, be stored in the storer, may further comprise the steps:
100, system powers on and carries out initialization,
200, wait for audio frequency acquiring and video instructions,, change step 300, otherwise continue to wait for if obtain acquisition instructions;
300, obtain video, voice data;
400, according to the different-format storage file.
Concrete, in the above-mentioned kind audio frequency and video acquisition method: comprise step by step following in the described step 100:
110, carry out initialization in the following order:
111, initializing signal receiver;
112, initializing signal detuner;
113, initialization USB controlling receiver;
Comprise step by step following in the described step 300
320, etc. pending data arrives, if data arrive, is sent to data filter;
330, calls application interface.
Further, in the above-mentioned kind audio frequency and video acquisition method: comprise step by step following in the described step 400:
410, judge form,, otherwise forward 430 to if picture then forwards 420 to;
420, judge picture format, if JPG then saves as the JPG formatted file, if the BMP form then saves as the BMP file;
430, judge whether it is the VCD file,, finish, otherwise forward step 431 to if then save as the file of VCD form;
431, judge whether it is the SVCD file,, finish, otherwise forward step 432 to if then save as the file of SVCD form;
432, judge whether it is the DVD file,, finish, otherwise forward step 433 to if then save as the file of DVD form;
433, judge whether it is the WMV file,, finish if then save as the file of WMV form, otherwise; Save as the file of AVI form, finish.
The invention has the beneficial effects as follows: the present invention is concerning the user, and the collecting efficiency of raising has been simplified operation easier, has made things convenient for use.Especially the adding of dynamic video is more directly perceived.
Below in conjunction with the drawings and specific embodiments the present invention is done comparatively detailed description.
Description of drawings
Accompanying drawing 1 is product block scheme of the present invention.
Accompanying drawing 2 obtains video/audio data procedures process flow diagram in the embodiment of the invention.
Accompanying drawing 3 is that the embodiment of the invention 1 drives sequential flowchart.
Accompanying drawing 4 is that the embodiment of the invention 1 is preserved the file process flow diagram flow chart.
Embodiment
Embodiment 1, and as shown in Figure 1, Figure 2, Figure 3 and Figure 4, present embodiment is that module is carried out the method that audio frequency and video is gathered as shown in Figure 1, and each module declaration is as follows among this modular structure figure:
Input port module: the input port of various signals (as composite video, HDMI, component input, S terminal etc.).
Data acquisition module: the AV signal of input is changed into the file that computer can be discerned.
Computer link block: the digital signal after the conversion is imported into computer.
Concrete, a kind of audio frequency and video acquisition method receives the AV signal of importing, and converts TV signal to digital signal, is stored in the storer, may further comprise the steps:
100, system powers on and carries out initialization,
110, carry out initialization in the following order:
111, initializing signal receiver;
112, initializing signal detuner;
113, initialization USB controlling receiver;
200, wait for audio frequency acquiring and video instructions,, change step 300, otherwise continue to wait for if obtain acquisition instructions;
300, obtain video, voice data;
310, etc. pending data arrives, if data arrive, is sent to data filter;
Here data filter is a kind of program assembly of system drive framework definition, and it mainly for information filtering useless, mistake, sends Useful Information to next program assembly and go to handle analysis.
320, calls application interface.
General application programming interfaces are one group of common interfaces that operating system provides for the hardware driving framework.General harvester has only been used the single frames data-interface, so can only gather the single frames data.The driver of this device realized obtaining of video flowing and transmitted, so the video data that application interface can collection activity.
400, according to the different-format storage file.
410, judge form,, otherwise forward 430 to if picture then forwards 420 to;
420, judge picture format, if JPG then saves as the JPG formatted file, if the BMP form then saves as the BMP file;
430, judge whether it is the VCD file,, finish, otherwise forward step 431 to if then save as the file of VCD form;
431, judge whether it is the SVCD file,, finish, otherwise forward step 432 to if then save as the file of SVCD form;
432, judge whether it is the DVD file,, finish, otherwise forward step 433 to if then save as the file of DVD form;
433, judge whether it is the WMV file,, finish if then save as the file of WMV form, otherwise; Save as the file of AVI form, finish.
