Abstract

In an error correction circuit, when a data loss is detected, substitute data comprising all bits of "1" or "0" are generated during a data loss period and substituted for the lost data for the data loss period. Thereafter, the whole data containing the substitute data are decoded in a predetermined error correction system to generate corrected data.
