Abstract
A method of and apparatus for allocating memory for storage of vocabularies used in adaptive data compression of a frame-multiplexed data stream of a data communications network. More specifically, a memory of a data compression encoder of the network is partitioned into a plurality of sections for the temporary storage of a corresponding plurality of data compression vocabularies. A memory section of the plurality is assigned to a current frame of the frame-multiplexed data stream based on information of the current frame for storage of a vocabulary created adaptively from the current frame.
