An On - line Variable Length

We present a methodology of an on-line variable-length binary encoding of a set of integers. The basic principle of this methodology is to maintain the preex property amongst the codes assigned on-line to a set of integers growing dynamically. The preex property enables unique decoding of a string of elements from this set. To show the utility of this on-line variable length binary encoding, we apply this methodology to encode the LZW codes. Application of this encoding scheme signiicantly improves the compression achieved by the standard LZW scheme. This encoding can be applied in other compression schemes to encode the pointers using variable-length binary codes.
