ABSTRACT:
A zero stripper (10) accepts individual bit sequences marked off by a break codes in a bit stream, deletes any leading “0” bits from such bit sequences so as to form a zero-stripped datum segment, counts the number of bits in each resultant datum segment, and then concatenates each such datum segment with the bit count of that datum segment into the code formin-line-formulae description="In-line Formulae" end="lead"?nnnndddddd . . . ,in-line-formulae description="In-line Formulae" end="tail"?where the “n's” are the bit count and the “d's”are the successive bits. Substantial bit space in transmission in thus saved. A “type code” “tt” can also be added if defined in the original data. The zero-stripped data can be reconstituted at the receiving end if needed, i.e., if the receiving device accepts only fixed length bytes. Also included are new and simple arithmetic routines.
