Patent Images

1. A method of encoding a sequence of images of a digital motion video signal, said method comprising the steps of:

  • a performing a preliminary analysis of the entire sequence of images to determine complexity values, each complexity value being associated with at least one of said images and, after completion of said preliminary analysis;

    b compressing the images of said sequence of images using a compression system including a compression controller having adjustable settings for scaling compression system quantizers and thresholds; and

    c adjusting the compression controller setting for each image being compressed in accordance with adjustment parameters including at least one complexity value associated with an image occurring in the sequence subsequent to the image being compressed.
