Abstract
Fixed-length segments of a variable-length encoded (VLE) bitstream are used as indices into a lookup table. The current table entry is interpreted to determine how many complete VLE signals are in current bitstream segment. If the segment contains one or more complete VLE signals, then the corresponding decoded signals are retrieved from the table entry. Otherwise, if the segment contains no complete VLE signals, then special processing is performed to decode the segment.
