In transcoding a frequency transform-encoded digital video signal representing a sequence of video frames, a foveated, compressed digital video signal is produced and transmitted over a limited bandwidth communication channel to a display according to the following method: First, a frequency transform-encoded digital video signal having encoded frequency coefficients representing a sequence of video frames is provided, wherein the encoding removes temporal redundancies from the video signal and encodes the frequency coefficients as base layer frequency coefficients in a base layer and as residual frequency coefficients in an enhancement layer. Then, an observer's gaze point is identified on the display.
