1. A wireless communication unit, comprising:

  • at least one digital transceiver operable to transmit and receive compressed video and audio signals over a fixed bandwidth;

    a controller operable to dynamically allocate the fixed bandwidth among the video and audio signals, the dynamic allocation being performed by varying the rates at which the audio and video signals are compressed;

    wherein the fixed bandwidth is an RF bandwidth; and

    wherein the controller performs the step of generating an error signal indicating a difference between first and second signals representing the fixed bandwidth and the bandwidth allocated to one of the audio and video signals; and

    wherein the transceiver performs the steps of;

    varying the compression rate of one of the audio and video signals in response to the second signal; and

    varying the compression rate of the other one of the audio and video signals in response to the error signal.
