Description
Technical field
The present invention relates to a kind of method of handling the video/audio signal, particularly when the digital recorder device is carried out recording function, the method that the video/audio data of having stored is edited simultaneously.
Background technology
Traditional video recording mode is used the analog format storage mostly, but because of it has the easily damp and mouldy long preservation that is difficult to, reuse or duplicating image quality meeting deterioration or distortion, writing time, short often the need manually changed, take up room, the easy dirty damage of magnetic head and check record shortcoming such as time-consuming, so inconvenience in many uses is arranged, so just there is the recording apparatus of number format storage to occur, because it converts analog signal to digital signal, after handling, digital compression is stored in CD or hard disk and other media, so even repeated use or repeatedly duplicate and long preservation can not influence the video/audio quality.Yet because computer technology is flourish now, arithmetic processor speed is more and more faster, compress technique constantly improvement and storage medium capacity is increasing, so the digital recorder device of recording a video with digital form such as digital videocorder (DVR) and digital camera projector (digital camcorder) etc. are flourish has become to drive gesture.
On the whole general digital recorder device can be divided into PC architecture design and non-PC architecture design, and the hardware of the digital recording device of PC architecture design mostly is ready-made computer parts, adding the capturing images card assembles, and this digital recorder device uses various OS job platforms, and its for example picture demonstration of most of function, dividing processing, compression storage, displacement comparison, data search broadcast and Network Transmission etc. then are to handle computing via central processing unit again with software control.Though having the high and various functions of treatment efficiency, it expands easy advantage, but shortcoming is what follows also arranged, one is for each does different designs at varying environment or demand owing to hardware that each manufacturer developed and software, so often because of compatibling problem or design factors such as improper, cause system's conflict, it two is because of job platform, software such as driver and application program all is stored in hard disk, so often because of read-write or covering mistake, cause file to damage and crash, it is three for often stopping production because of parts or in short supply, must change the specification or his the factory's product of arranging in pairs or groups, the quality keyholed back plate is difficult for, so less stable, it is four for owing to need assemble hardware and installation initialization system platform by the professional, so the user who is unfamiliar with computer causes the puzzlement of sellers' after-sale service and maintenance often because of operating mistake causes deadlock.
And the digital recorder device of general non-PC architecture design is to belong to a kind of enclosed design, as digital videocorder and digital camera projector, usually this device operational function is comparatively simple, as household electrical appliances such as CD, DVD player, be at the required function custom-made by size, design proprietary circuit and IC assembly, and the system of independence control, so system stability and operate simple and easy.And be different from the PC framework the digital recorder device be, its most function is with hardware handles, according to every required function and use various IC process chip, and with the Control Software burning in programmable IC or read-only memory.So the shortcoming that no program is damaged, not like the PC framework, often because of closing tester in power-down state, or the read-write mistake causes program to damage and crash.Another advantage of the digital recorder device of non-PC architecture design is, just as using traditional video tape recorder, do not need the complex installation program, need not change original miscellaneous equipment yet, plug and play is installed simple, and interface operable is similar, quite can meet consumer's use habit, also the puzzlement of keeping in repair than fault-free.
Yet the digital recorder device of non-PC architecture design in the past, it is recorded the video/audio data of finishing and is stored in a storage device usually earlier, DVD for example, VCD or tape etc., again the storage data on this storage device are sent to enterprising line data format conversion of computer or editor by computer peripheral apparatus, and must record fully via the digital recorder device in this section video/audio data and just can be sent to the editor that makes amendment on the computer after finishing, this has promptly reduced the convenience of revising the edited image voice data, also having increased simultaneously this video/audio data of necessary wait records fully and finishes and change time to computer system over to, thereby reduced ageingly, simultaneously also fail to meet the trend of information household appliances hommization operation-interface.
Summary of the invention
Therefore main purpose of the present invention provides a kind of method of handling the video/audio signal, to solve the above problems.
A kind of method of handling the video/audio signal that the present invention discloses, it comprises the following step: (a) utilize a receiver module to receive one first video/audio signal; (b) utilize a control unit that this first video/audio signal is sent to a coder-decoder so that this first video/audio signal is converted to one second video/audio signal, wherein this coder-decoder connects this receiver module and this control unit and this control unit and controls this coder-decoder; (c) utilize this second video/audio signal of memory device stores that is connected in this coder-decoder and this control unit, wherein comprise one the 3rd video/audio signal in this this storage device of control unit may command and this storage device; (d) in execution in step (a) in (c), utilize this control unit that the 3rd video/audio signal is passed to this coder-decoder and utilize this coder-decoder that the 3rd video/audio signal is deciphered to become one the 4th video/audio signal; (e) utilize this control unit that the 4th video/audio signal is passed to an editor module; And (f) utilize this editor module editor the 4th video/audio signal to become one the 5th video/audio signal.
The invention has the advantages that can be when the digital recorder device be carried out recording function, on this digital recorder device, simultaneously the video/audio data of having stored is carried out edit-modify, with the convenience that increases the edited image audio function and ageing, and meet the trend of information household appliances hommization operation-interface.
