<p>A coding apparatus for coding digital data comprises an encode circuit for encoding digital data, and an error correction code adding circuit for adding error correction codes of different bit numbers to respective encoded digital data. Also, a transmitting apparatus comprises an encode circuit for encoding digital data, an error correction code adding circuit for adding error correction codes of different bit numbers to the respective encoded digital data, a circuit for transmitting encoded data with the error correction code added, a circuit for receiving the transmitted data, a circuit for error-correcting the received data by using an error correction code contained in the received data, and a circuit for decoding the error-corrected data. Further, a coding method for coding digital data comprises the steps of encoding digital data, and adding error correction codes of different bit numbers to the respective encoded digital data. <IMAGE></p> |
