LED display to image signal processing method

LED display to image signal processing method

A kind of method is adopted dedicated big led screen signal processor, the interlaces the TV signal processing, manufacture progre ive-scan signals into, and then play on the big led screen. High performance processing function processing as high as 10 digits, more than in scans transform to interpolation operation, motion prediction and compensation and scanning transform, etc. Now high order large LED screen also are using this method, and for more image signal processing, tries to put the signal to ascend to the broadcast, of course, the effect also better. Computer images also should pass the processor processing and then to the big led screen.

Another method is the multimedia method, usually called synchronization method, this method is to use a screen capture of ordinary multimedia card, and TV signal demodulation, filter and separating the tone. Image signal the A/D transformation and MPEG compression coding, so that storage. When play again, direct solution compress in computer monitors on the watch. Sent to the big led screen signals through the special adapter card from the computer interface or DVI display card, adapter card will also get some processing. At this moment, big the screen of the computer monitor or equivalent to actually on the part of the window, often called, can realize the one-to-one displayed. Due to manufacture progre ive-scan is computer monitors, so if not for the show signals sent operations do processing, then smoke frame, big screen display format is monitor format.
