Description
Technical field
The utility model relates to a kind of multimedia digital videocorder, and You Zhike monitors simultaneously, records a video, the effect of recording and audio-visual broadcast, and is stored in internal storage location simultaneously, is utilized multimedia playing module to do audio-visual broadcast simultaneously again.
Background technology
Press, often having many unexpected situations in the living environment produces, and when producing, situation must do suitable strain and processing, to avoid situation to worsen or the more serious problem of deriving, therefore when unexpected situation produces, can do appropriate strain and processing in the very first time, be to slow down the suitable processing mode that unexpected situation enlarges, and unexpected situation takes place in the living environment, have indoor, the modal unexpected situation in outside, gas leakage for example, fire, situations such as burglar thieves or robbers who act under cover of night invasion, the lighter's wealth that loses money, injuredly send the doctor, weight person family ruins the people and dies, life threatening; The most incidental in the public place then is the robber, violent, have a fist fight, it is unexpected to fight at close quarters etc., so before unexpected situation produces, if can appropriateness carry out precautionary measures, can reduce the unexpected injury that is caused, guarantee life, the safety of property, at present for indoor, mistake is arranged in the prevention that the unexpected situation of outside and public place etc. is carried out, common person installs to save defence system from damage, with indoor by the safety system detecting, the changing condition that the outside environment is produced, and can circulate a notice of fast, and reach the fast processing unusual condition, to reduce the unexpected loss that is caused.
So, the at present employed defence surveillance (CC-TV) of saving from damage, the video tape of its video-recorder recording equipment, be to adopt analog form, need change video tape at any time, and its image quality definition is relatively poor, recording function is limited, is the analog image that video camera is absorbed, and utilizes main control system externally connected with display screen curtain to manifest image, and external video tape recorder is recorded a video simultaneously, then the external facility of main control system are many more, the transmission line that is twined around it, power line is also many more, and main control system can only be controlled its running by the adjustment button on the panel, when using, reality still has many disappearances, as:
(1) main control system also can't directly store image signal, can not utilize other coffret with the memory storage data, only by external video-cassette recorders recording image, the service time that is subject to shadow bands again is limited, approximately has only one hour video time, record a video and must constantly repeat to change shadow bands, cause quite trouble and inconvenience when using.
(2) main control system can only can not be done the broadcast of image with the shadow bands recording image, if need watch image the time, must utilize projector just can watch storage image in the shadow bands, if there is emergency episode then easily to miss the strained handling of the very first time.
(3) main control system inside there is no internal memory is set, therefore can not recording image, when external video tape recorder fault or shadow bands use up, main control system i.e. recording image again, the function of surveillance keyholed back plate will be influenced, deposit card if chance emergency episode or accident can not be recorded a video, have a greatly reduced quality saving defense function from damage.
And after the digital Age arriving, traditional analog image processing pattern, also replaced by digital facility gradually, then brand-new digital VTR (DVR, Digital VideoRecorder) comes out, enlarged the function of surveillance, except traditional signal line transmits image, also can pass through network, modes such as wireless transmission, the image signal that video camera absorbed is done transmission, kinescope image quality is more clear, function is also more, only, present employed digital VTR (DVR), though built-in hard disk is arranged, data burning CD-ROM drive, but memory size is limited, only can do the data backup and can not do real-time access by data burning CD-ROM drive, must be with access, burn job is separately carried out, certainly can not be with memory card, multimedia memory apparatus such as dish or external connected hand disk are done the storage of audio-visual signal with oneself, then the storage volume for digital VTR expands and storing mode, still exist in considerable problem, and desire to watch when monitoring image, still need the externally connected with display screen curtain, the image that could show video camera, not only need spend the expense of buying display screen, and display screen also takes up space, still there are many inconveniences in the use, some digital VTR is because of the control system complexity, operation push-button is many and complicated, must utilize computer system to reach administrative purposes by management information system MIS (Management Information System), the networking running that perhaps utilizes it and network management (networkmanagment) computer system operator to come managing computer system, also or pass through the professional and technical personnel, the personnel of controlling operate, the running of control figure video tape recorder, the operation running quite is not easy, and still there are many disappearances when using in it, as:
(1) digital VTR (DVR) is continuous operation in 24 hours, therefore built-in hard disk continuing under the operating position, cause shorten relatively the useful life (using only about 3～4 months) of hard disk, cause when changing the hard disk of in-building type, its operation procedure is comparatively loaded down with trivial details.
(2) present employed digital VTR (DVR), only can make the mechanism of single monitoring for the user, can't carry out the multimedia video playing function simultaneously, then must buy more display screen and multimedia playing apparatus again if desire to do audio-visual broadcast simultaneously, and buy more display screen and other video-audio playing device again, not only sink money, also take original space, increase the degree of difficulty of operating.
(3) present employed digital VTR (DVR) only has single operating and controlling interface, so control button is also more, increase the difficulty when using, needs the professional and technical personnel to instruct usually, perhaps need consult service manual, causes the trouble and inconvenience of use.
Be with, how to solve commonly use surveillance do not have display screen, can not Extended RAM etc. the problem of use aspect, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.
