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:

  • compressing a video stream received from a video stream source using a video compression with FGS to generate a compressed output video stream having a base layer and at least one enhancement layer, wherein the video compression is performed in response to a feedback control input signal received from a display, the feedback control signal for use in controlling a modulation and optimization of the compressed output video stream; and

    transmitting the compressed output video stream to the display.
