Abstract
An error correction system of digital data for use in a digital VTR or a digital TV constituted as parts of a digital processing system, which is provided with an ECC outer encoder, a shuffling means, an inner encoder, a tape, an ECC inner decoder, a de-shuffling means and an ECC outer decoder to perform the double encoding/decoding, comprises a memory address generating circuit for enabling the de-shuffling portion to generate addresses increasing toward the column from the first address of write addresses, a de-shuffling memory circuit for storing data and error flags and a path control circuit for controlling the input/output of data and error flag memories. Thus, it makes use of an ID signal identifying the position information of data recorded on a tape and an error flag confirming whether the reproduced data is error or not, so that it controls the write addresses and input/output paths of the data and error flag memories to minimize the loss of recorded data, thereby improving the quality of the image to be reproduced.
