Appeal No. 2000-1282
Application No. 08/813,140
performed in a two-phase operation in first and second
portions of a digital memory.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. Apparatus for recording a digital signal and
redundancy signals such that said digital signal may be
reproduced by error correcting the recorded digital
signal using the redundancy signals, comprising
a digital memory,
a digital storage system providing recordation of
digital information,
error correcting circuitry receiving a group of
digital signals and generating therefrom redundancy
signals to be used in error correction of said digital
signals, and
control circuitry controlling operations of said
memory, said digital storage system and said error
correcting circuitry to receive digital signals from a
signal source, error-encode and record the error-encoded
digital signals, wherein
said control circuitry, in a first phase of a
recording operation performed during a first period of
time, causes a first error-encoded digital signal in a
first portion of said memory to be forwarded to said
digital storage system for recordation, and causes
digital signals from said signal source to be stored in
place of said first error-encoded digital signal, while
simultaneously causing said error correcting circuitry to
error encode digital signals stored in a second portion
of said digital memory to form an error-encoded result
and store said error-encoded result into said second
portion of said digital memory,
