Description
Technical field
The utility model relates to video field, relates in particular to field of video processing, particularly relates to a kind of portable video treatment system.
Background technology
As everyone knows, VHS is the abbreviation of Video Home System, means video home system.It is to be recorded and playing standard at a kind of home video tape recording of exploitation in 1976 by Japanese JVC company.
The 1980s, after the competition of having experienced with the Betamax form of Sony and the Video2000 form of Philip, VHS becomes the reference format of home video tape recording.VHS provides the reproduction time longer than Betamax form, and magnetic tape transport does not have again Betamax so complicated simultaneously.VHS is more a lot of soon than the F.F. of Betamax and astern speed, because before high-speed magnetic tape scrolling, plays magnetic head and has left tape.On the other hand, the picture quality of Betamax form is more better.
VHS also has more market in the U.S. and Japan, also has a lot of video tape leased enterprise that leasing of VHS video tape is provided.Along with VHS equipment is gradually by DVD, blue light equipment replacement, need a kind of video process apparatus of cheapness, the record/player of one building on its basis.Described recording/player price, compared with VHS recorded broadcast equipment, possess enough competitiveness.
Visual information is the main source that the mankind obtain external information, because nearly 70% information obtains by human eye.Along with multimedia technology develop rapidly, video image has obtained extensive attention and application.And application spreads all over the aspects such as radio and television, medical science, guard monitor, parking lot management, military affairs and life science.The lifting of video capture technology and Display Technique, makes people more and more higher to the requirement of image quality.But the transmission of image and conversion cause the reduction of picture quality always to a certain extent in all kinds of picture systems.For example: some outdoor monitoring systems often can only could normally be worked under fine day, greatly reduce at the bad weather such as dense fog, sand and dust or low light situation hypograph contrast, and people cannot therefrom obtain useful information.Moreover, watch for a long time video that quality is low may increase the weight of the burden of people's eyes, easily produce visual fatigue, even can have a dizzy spell.In the time there is the bad weathers such as dense fog, heavy rain, sand and dust, the contrast of outdoor scene image and color all can be changed or degenerate, and the many features that contain in image are all capped or are fuzzy, have all caused great difficulty for all kinds of monitoring.Therefore, give full play to the usefulness that monitors video, just must be to monitoring that video image strengthens processing.
In the application of Network Video Surveillance and demand stream media system, watch end to carry out the general fashion of video request program as follows:
1) user by system to wanting the video flowing of program request to select in advance or set image resolution ratio, frame per second, code stream size etc.;
2), when user is in broadcast window when order video, system is by the image resolution ratio transmitting video-frequency flow setting in advance according to user and show.
But, when watching the video display area size of end to have when unchanged, video flowing is always according to being transmitted by predefined image resolution ratio, frame per second or code check etc., and keep fixing always, it doesn't matter to watch the parameter selections such as the variation of end video display area size and the resolution of the video flowing of transmission, frame per second, code stream.
In the time watching the video display area of end to narrow down to being less than the size of video image of transmission, because viewing area diminishes, often need to reduce image pixel downscaled images size, could in current display area, show entire image, but, real image display resolution obviously reduces, and the code stream of actual transmissions and bandwidth requirement do not reduce, and has wasted transmission bandwidth resource; When user in order to see image detail clearly enlarged display area when being greater than the size of video image of transmission, although show again after can amplifying processing to image by some algorithms, but be generally difficult to the image of rediscover, its actual result is that user cannot clearerly see image clearly, thereby the meaning that has lost user enlarged display area, user experience is poor.
Along with traditional CRT monitor and TV are withdrawn from the market gradually, become the main flow display in current demonstration market taking fixed pixel as main flat-panel monitor, comprise LCD (LiquidCrystal Display, liquid crystal), DLP (Digital Light Projector, digital light projection), LCoS (liquid cry stal on silicon, liquid crystal on silicon) and PDP (plasma display panel, Plasmia indicating panel).All these technology are all to create by different way electronic image, but they but have same feature: the imaging pixel of fixed matrix, this fixed pixel structures shape the physical resolution of display.
Current in professional audiovisual, radio, TV and film industries, specifying the company of associated video, image international standard to have 3 normal structures, is respectively ITU (International Telecommunication Association), SMPTE (Society of Motion Picture and Television Engineers) and VESA (VESA).These normal structures have completed the fusion of video and image two large series standards substantially, thereby have further accelerated video and the fusion of image product on products at different levels.Therefore, can see the interface that has occurred image on DVD, and on computer, occur the interface of video.Physical interface difference and the compatible standard difference of these products, brought a lot of obstacles to docking and connection between equipment.
Due to the compatibility of the display as display terminal and equipment interconnection, bring unlimited opportunity to birth and the development of video processor.
In addition, the requirement of merging for signal monitoring, mux--out signal exhibits and multisystem light of stage along with professional audiovisual, radio, TV and film industries constantly promotes, and has brought opportunity to video processor in the development of the technology such as the processing of many pictures, large-screen splicing, synchronous, the nonstandard video scaling of video and audio, Fusion Edges, image co-registration.
Video processing is a field that involvement aspect is very wide, has the various functions such as video format conversion, color space conversion, figure are cut apart, Graphics overlay, convergent-divergent, effect process.Existing video processing technique system major part is all simple function or certain several function synthesized.In addition, also there is relatively comprehensively video frequency processing chip of some functions, but ensure chip functions fully, rationally utilize, make the whole processing system for video that comprises this chip can realize preferably treatment effect, and provide friendly, understandable simultaneously, operation interface will be developed its peripheral circuit clearly.Concerning user, development difficulty is larger, and has strengthened development cost, lengthened the construction cycle.
Video-splicing system on market now, attainable function have cut apart, split screen demonstration, windowing, window roaming, owing to adopting hardware splicing, it is Real time dynamic display completely that image is processed, image stack, fitting operation is simple, start-up time is fast, can control with RS-232, and window is fixed as a screen size, can amplify, dwindle or move, can support multi-screen splicing.Whole system closed operation, is not affected by any virus, without installing operating system, and plug and play.Every road RGB passage independently calculates, and it is more careful that signal is processed; RGB, video image can superpose mutually; Vision signal processing has motion compensation, can eliminate the crenellated phenomena of motion video; Adopt realtime graphic processing, inner parallel bus framework; Every road input channel is independent bus line, this plate card type controller (shared bus) system processing power is stronger mutually, processing speed is faster, output image is more smooth, possess RS-232 communication interface, can conveniently be used in conjunction with computer, remote control system or various remote control equipment (central control system).
Although splicing to user, the control of RS-232 communication interface brings great convenience and user's experience, control function but require user and control appliance to realize in limited distance, its realization (more than 1 kilometer) Long-distance Control will be added repeater and be reached remote control ability, do like this to engineering cloth tape and carried out greatly challenge, this is higher to realize cost, and signal quality cannot ensure completely.CPU must be fixed in a specific operating room in addition, cannot adapt to from now on the demand of office flexibly.Therefore need a kind of new scheme to solve these problems, with the overall construction cost of trying one's best, improve communication quality.
