Abstract
A new general scheme is introduced that allows bidirectional decoding of va riable length coded bitstreams from either end. Except for a small fixed nu mber of extra bits appended to a sequence of code words, the scheme is as e fficient as Huffman coding. The extra operations required at coder and deco der are code word reversal and one EXOR for each bit.
