Description
Technical field
The utility model relates to a kind of high definition three-dimensional video-frequency driver that can the high definition stereo video streaming be converted into right and left eyes two independent high definition video steaming, belongs to three-dimensional image video conversion and video electronic technical field.
Background technology
1, look point-score: the present comparative maturity of this technology; Red indigo plant, green red, three kinds of main patterns of champac are arranged; Principle all is that the image with two different visual angles is synthesized to piece image with different colours, through tinted glasses go decoding watch left and right sides image, the advantage of this method be simple to operate, production cost is low; Shortcoming is that color reducibility is poor, causes visual fatigue easily.
2, time-sharing procedure: the principle of the three-dimensional mode of time-sharing procedure is to utilize the persistence of vision characteristic of human eye; Left and right sides image sequence is successively got into right and left eyes; To reach the stereopsis effect; Time division type spatical television set and time division type stereo projector can realize that the stereogram of 1920x1080 full pel watches, and this is its advantage.But nonsynchronous phenomenon that eyes are watched can take place in the three-dimensional mode of time division type (switch glasses).So watch dynamic stereoscopic TV or three-dimensional film will produce dizzy phenomenon.The time division type glasses also exist cost than shortcoming higher, easy damage.
3, light point-score: the light point-score adopts left and right two mutually perpendicular polarized light pieces, be installed at projection lens before; Get into the right and left eyes that spectators wear the polarized light piece glasses respectively after making left and right sides separation of images become mutually perpendicular polarization light, by the visual effect of cerebral nerve stack generation 3 D stereo, owing to its left and right sides image is watched synchronously, so visual comparison is comfortable.But about the image arranged of compression and last lower compression if without signal processing, it only is the HD video pixel half on brightness and pixel, can only realize 1920x540 pixel stereogram, can not really realize the 1920x1080 high-definition image.
4, in present society, favourablely realize the method that stereo video signals is changed with computer and application software, the advantage of this method is can the video source of computer inside be handled.There is the shortcoming of two aspects in it: first computer is computing when can't carry out external input signal with the output signal, so can't carry out input signal and the real-time conversion of exporting signal.It two is too loaded down with trivial details through computer mouse operation, so be difficult for extensively promoting.
The utility model content
Purpose of design: avoid time-sharing procedure three-dimensional video-frequency persistence of vision to produce the asynchrony phenomenon that causes; Brightness and the pixel of avoiding the light point-score to cause are lost; Design about a kind of the support, up and down, the 3D video source input of staggered rows, front and back frame; Can export the independent full HD video of the synchronous two-way of right and left eyes simultaneously in real time, and image there is not staggered, no stroboscopic, not dizzy, high definition three-dimensional video-frequency driver easy to use.
Design: in order to realize above-mentioned purpose of design.1, adopting the signal source of high definition playback equipments such as high definition player or high definition STB as high definition three-dimensional video-frequency driver, is one of characteristic of the utility model.The purpose of doing like this is: can make the source variation of video source, both can derive from TV station, also can derive from storage mediums such as network, hard disk, USB flash disk, CD.2, both supported the vision signal of 1080p form, also supported the vision signal of 1080i form, and can detect simultaneously the design of identification automatically, be the utility model characteristic two.The purpose of doing like this is: make the compatibility of the utility model stronger, and can compatible more input source.The design that inserts when 3, supporting multipath video source, be the utility model technical characterictic three.The purpose of doing like this is: can make the convenient at any time switching of user want the video source of watching.4, adopt infrared remote-control device, control the switching of various 3D patterns, the switching of video source and the design of other controlled function, be the utility model technical characterictic four.The purpose of doing like this is: user-friendly.
Technical scheme: a kind of high definition three-dimensional video-frequency driver; Comprise power supply; Multichannel HDMI interface or other video interface signal input parts receive high definition video steaming; Multichannel HDMI interface or other video interface signal output parts connect HDMI decoder signal input respectively, and HDMI decoder signal output connects the signal input part of FPGA respectively, and the signal output part of FPGA connects HDMI code device signal input respectively; HDMI code device signal output connects HDMI interface or other video interface signal input parts respectively, and HDMI interface or other video interface signal output parts are respectively as independently right and left eyes signal output.
The utility model is compared with background technology, and the one, can support the high definition right and left eyes output of real 1920x1080; The 2nd, video to be decoded and handle through hardware mode and make to play smoothly, stereoeffect is strong, exports no stroboscopic, no ghost image, the right and left eyes image is synchronous fully, is the three-dimensional video-frequency driver of true health; The 3rd, watch cost low, only need the polarizer glasses just can watch stereoeffect true to nature and experience personally; The 4th, adopt infrared remote control to select to different patterns and input, simple and clear easy-to-use; The 5th, structure size is the same with the ordinary playing device, the convenient placement.Satisfy the demand that people's stereoscopic video is viewed and admired thereby solve, solved people and wanted solution for a long time, and do not had the technical barrier of solution, can obtain good economic benefit and social benefit.
