Abstract
A system for displaying video on electronic paper displays to reduce video playback artifacts that includes an electronic paper display, a video transcoder, a display controller and a waveforms module is disclosed. The video transcoder receives a video stream including pixel data for presentation on the electronic paper display. The video transcoder processes the video stream and generates pixel data that is provided to the display controller by processing a desired value for a pixel of video data and a future value for the pixel of video data. The video transcoder adapts and re-encodes the video stream for better display on the electronic paper display.
