More preferably, described video/audio signal input port receives the video/audio signal from video and audio equipment.Wherein, described video and audio equipment comprises at least one in TV, Set Top Box, DVD player or computer, both can be TV and the combination of the different video and audio equipments such as DVD, computer, also can be the combination of two identical video and audio equipments, can certainly comprise that other video and audio output equipments are linked into 3D binary channels box, vision signal is processed through synthetic, and audio signal is directly transmitted.
Mainly contain on the market at present two kinds of 3D technology, one is shutter 3D, and another kind is not flash 3D.Shutter 3D is mainly the picture of having recorded respectively right and left eyes in the time taking, in the time playing, wear shutter type 3 D spectacles, control the folding of glasses, allow human body distinguish the image of perception right and left eyes, thereby synthetic 3D vision in brain, but on 3D technology realizes, the refresh rate of shutter liquid crystal panel will reach 120Hz or higher, and there is stroboscopic, crosstalk, the problems such as brightness reduction.And not flash 3D carries out combing to polarised light, allow respectively right and left eyes see vertically and the image of level in conjunction with polarising glass, finally by brain compound stereoscopic image.Not flash 3D technology is to have increased filter coating, can retain the advantages such as glass type polarization light technology flicker free, and relatively be conducive to reduce costs.The native system basis on the market 3D TV of main flow is carried out technological improvement, the treatment technology adopting is developed based on not flash 3D technology, because not flash 3D technology is owing to there is no stroboscopic, brightness does not have obvious reduction yet, visible angle is good, glasses are frivolous comfortable, and owing to charging, there is no electronic devices and components, zero radiation health environment-friendly more, can reduce accordingly human-body fatigue, from health perspectives and angle of sustainable development, not flash 3D technology is a reasonable selection.
At present conventional 3D shows that image-forming principle is in the time that people see things, is fused into a picture and produces third dimension by entering the difference of two different pictures of right and left eyes through brain.And 3D TV is on the market exactly based on this principle, play the picture through special synthetic processing, and export two groups of picture signals of a road AB at display screen, receive 2 kinds of unlike signals by the 3D glasses of special processing simultaneously, left side glasses receive the a-signal that screen sends, the right glasses connect the B signal that screen sends, and two kinds of signals synchronously enter respectively right and left eyes, process and generation 3D image through brain.If two eyeglasses of glasses are all left eyeglasses, beholder can only see A a series of paintings face; If two eyeglasses of glasses are all right eyeglasses, beholder can only see B a series of paintings face.
Binary channels technology: this technology is mainly derived from the research of human eye, why human eye can observe the world has third dimension, because there are two eyes for people is long, in the time that we observe things, the parallactic displacement that two eyes cause is through the analysis of brain, will distinguish the distance of object distance, thereby produce strong third dimension.The composition principle of 3D rendering is exactly based on this technology, two width 2D pictures are synthesized to a width 3D image by the principle of 3D rendering, thereby play on 3D TV, so a width 3D picture of playing on 3D TV is synthetic by the different 2D image of two width simultaneously, the camera that this two width image is same level from different perspectives photographs.Therefore two groups of video output pictures can reduce and be output as binary channels picture, by the 3D image that shows that on 3D TV image combining that two width are not theed least concerned forms simultaneously, carry out the separation of image by different glasses, thereby realize and on same screen, play two different pictures simultaneously, and then reached twin-channel effect.
In order to coordinate the output of binary channels video, this method configuration two-way two covers do not interfere with each other, independently audio frequency output mutually.Separated from each other, separate when this also just needs two-way audio to process, so native system employing is the different Bluetooth transmission unit of two-way, thereby realizing double-channel audio synchronously exports, adopt two CPU processing units of master chip, process thereby reach double-channel audio simultaneously, be independent of each other.Can certainly Ba Yi road signal audio system output by television set (for example adopting HDMI audio frequency, the audio system output such as coaxial).
In specific embodiment, 3D binary channels box adopts two paths of signals input pattern, and a road is that another road is the digital TV in high resolution signal of inputting by DVB module by the signal of network (wired ethernet or WIFI) input.User can select output mode by remote controller, the function that can realize between independent broadcasting 3 D videos, single channel and binary channels is switched, in the time selecting binary channels, system is a synthetic two-way 2D vision signal width 3D vision signal, be integrated into a road signal and be transferred to 3D television set, then by different 3D glasses, two kinds of pictures are parsed from 3D video, become the non-interfering vision signal of two-way, thereby realized twin-channel function.The audio frequency acquiescence of native system is transmitted by the different bluetooth of two-way, also can select to transmit by HDMI or audio frequency in a road, and the bluetooth of separately leading up to is transmitted,
Wherein video pictures is according to the Display Technique of 3D image-forming principle and 3D TV, become the picture of a width 3D to export the picture integrating of two mutually different 2D, then by 3D TV this 3D picture disply out, utilize two pairs to be respectively left eye mirror and can see with right eye mirror the picture that two width are different, on same TV, realize thereby realize the binary channels function of simultaneously exporting two width different pictures.Audio frequency processing is two parts completely independently, carries out processing respectively by two different CPU element simultaneously, simultaneously output.
This system, due to the particularity of system, need to have double-core CPU and the double-core GPU of the above dominant frequency of 1G at least, could process the different signal of two-way simultaneously, reaches the effect of simultaneously exporting two width different pictures at same screen.In addition because this system need to be exported the different audio signal of two-way simultaneously, so at least will there be two-way audio output system, consider this point, native system two-way audio acquiescence is used the different bluetooth output of two-way, can reach and not interfere with each other, cooperative feature, also can export by the audio system of television set by Ba Yi road audio frequency is set, thereby reach the effect of primary and secondary audio frequency, can many people in seeing same program, one or two people, in other things of operation, reach non-interfering effect.In order to expand the extensibility of this system, the input of this system has also adopted multichannel input mode, can be by the resource of the network mode input network facet such as WIFI or Ethernet, on the other hand also can be by DVB module input digital TV in high resolution resource, at this simultaneously, can also be by extending out SD card, the modes such as USB device are supported local resource.By multiple input pattern, make this box can reach better application.
Above disclosed is only the preferred embodiments of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to the present patent application the scope of the claims, still belongs to the scope that the present invention is contained.
