Appeal No. 95-3916
Application 08/008,292
This is an appeal from the final rejection of claims 26
through 28 and 30 through 36. In an Amendment After Final (paper
number 12), claims 26 through 28 and 30 through 32 were amended.
The disclosed invention relates to a code error correction
method and apparatus for decoding a digital information signal
comprised of a set of code blocks.
Claim 26 is illustrative of the claimed invention, and it
reads as follows:
26. A code error correction apparatus for decoding a digital
information signal comprised of a set of code blocks, said
digital information signal being received at least twice by
repetitive transmissions or repetitive reproductions of original
data, comprising:
error correction means for sequentially error-correcting a
set of code blocks of each digital information signal on a code
block basis, said error correction means providing a set of error
flags each representing whether or not the corresponding code
block is an uncorrected code block after error correction;
check information generation means for generating a check
information code for each of the code blocks after error
correction of a digital information signal, to thereby provide a
set of check information codes for each digital information
signal;
memory means having a memory capacity to store a set of code
blocks of one digital information signal and at least a set of
check information codes of said one digital information signal
and a set of check information codes of a subsequent digital
information signal, a same code block of different digital
information signals being stored in a predetermined same memory
location;
