Abstract
In accordance with the preferred embodiment of the present invention, excess power is distributed to certain streams in order to increase the stream's signal quality, and thus, its encoding rate. Although certain streams will have their overall power, and thus their signal quality reduced, in the preferred embodiment of the present invention the reduction in signal quality is limited so that the encoding rate for these streams remains unchanged.
