1. A method of modulating a compressed video stream for variable-bandwidth transmission, wherein the compressed video stream uses Fine Granularity Scalable (FGS), the method comprising the steps of providing a source of a video stream;

  • providing a display having means for generating a control input signal for controlling video compression;

    compressing the video stream from the source using a video compression with FGS to generate a compressed output video stream having a base layer and at least one enhancement layer, video compression performed based upon the control input signal from the display;

    transmitting the compressed output video stream;

    displaying the transmitted compressed output video stream.
