1. A method for communicating information in a packet-based communication system, the method comprising the steps of:

  • determining a total number of active channels of a given transport stream of the system to be coded at each of a plurality of code rates; and

    assigning the code rates to the active channels in accordance with a specified code rate assignment process, such that a bandwidth constraint of the transport stream is satisfied for a defined time period;

    wherein the code rates are periodically adjustable in conjunction with the assigning step as a function of the total number of active channels and the bandwidth constraint, such that unused bandwidth resulting from one or more channels becoming idle during the time period is distributable among the active channels.
