Method and system for efficient transmission of monochrome video data, in particular for laser beam scanning applications

Abstract

A method for transmission of monochrome video data of a monochromatic image, wherein three different source monochromatic pixels are encoded by a transmitting device into one compressed three-color pixel; the compressed three-color pixel are transmitted by the transmitting device. The transmitted compressed three-color pixel are received at a receiving device; and the compressed three-color pixel decoding are decoded by the receiving device into three different sink monochromatic pixels. The transmitting device acquires the three different source monochromatic pixels, extracts a single-color value from each of the three different source monochromatic pixels, and generates the compressed three-color pixel using the single-color values extracted from the three different source monochromatic pixels. The receiving device extracts the single-color value from the compressed three-color pixel and associates each of the single-color values extracted from the compressed three-color pixels to a respective pixel of the three different sink monochromatic pixels.
