ABSTRACT:
An adaptive cursor for interpreting displays of grouped data words highlights all of the bits of a segment associated with the bit position of the cursor. The grouped data words are extracted as an ancillary block from a serial digital input signal block. The format for the grouped data words is stored in a programmable read only memory (PROM). A microprocessor accesses the PROM according to the bit position of the cursor to determine the bits that make up the segment, and causes the segment to be highlighted. The microprocessor also decodes the segment to provide a corresponding alphanumeric display.
