video signals, the division of each cycle of the “binary
cyclic” signal into portions, or the specific circuitry for
processing video signals to produce the “binary cyclic”
signals. With the exception of the “binary cyclic” signal,
which would have been obvious to implement based upon the
teachings of Dillon, all of the limitations of these two
claims read directly on Dillon.
Dillon discloses a method and system for reconstructing
corrupted digital data words (i.e., “binary cyclic” signals)
transmitted from a base station to a radiotelephone in a
cellular radiotelephone system (column 3, line 42 through
column 4, line 9). Dillon samples a predetermined number of
equally time-spaced portions (e.g., bit by bit) in the
“cyclic” signal to provide sampled portions, with each of the
sampled portions having corresponding portions in respective
cycles of the “cyclic” signal. Dillon compares the sampled
bit position in data word 1 with corresponding sampled bit
positions in data words 2 and 3. For example, the error “x”
in the first bit position in data word 1 is compared with
first bit position “1" in data word 2 and first bit position
“1" in data word 3 (Figure 5). The error “x” in the first bit
