Mig-cl9000 splicer 3D implemented in LED display
Assuming the led display resolution is 1920 x 1080, the full-screen point-to-point 3D display will be made. In normal 2D mode, a 4-port sending card can carry the pixel.
First, point to point 3D video source: a single video source is divided into two images, one left eye and one right eye. Both eyes have a resolution of 1920 x 1080. The playback computer can choose dual DVI splicing output or DP to 3840 x 1080 x 60Hz. (if you don't do point-to-point, the video source is 1920 x 1080, or you can do a magnification.)
Secondly, the processing method of video splicer: images of different locations in video source need to be synthesized in different DVI and output to the sending card.
Finally, each 3D sending card will display the images received to the LED screen alternately with the left and right eye frames. Meanwhile, the infrared signal transmitter will control the left and right lens switch of the shutter 3D glasses synchronously, so as to present 3D stereo vision.
The 3D scheme requires video splicer:
1. The input, output and internal processing all require strict 60Hz. After sending the card frequency to 120Hz in 3D, there will be no frame loss, which is completely consistent with the characteristics of the whole channel 60Hz processing of CL9000 splicer.
2. The ability to repeatedly intercept images at different positions of the same signal source is the ZOOM function of CL9000 splicer, which is especially important when the pixel sizes of multiple sending cassette tapes are inconsistent.
3. Multi-preset switching facilitates seamless switching between 3D mode and 2D mode with one key and multi-window application in 2D mode (the sending card also needs to switch the corresponding mode).
