    Abstract: PURPOSE: A method and an apparatus for decoding a Reed-Solomon code are provided to efficiently decode a Reed-Solomon code by controlling the number of a modified Euclidean algorithm block and RAMs(Random Access Memory) according to the length of a code word demanded in a system. CONSTITUTION: A syndrome calculation block(110) calculates a syndrome for a received code word. One or more modified Eculid algorithm block(120) perform modified Euclidean algorithm calculation. An error location block(130) determines the location of errors based on the result of the modified Euclidean algorithm calculation. An error evaluation block(140) determines the value of the errors based on the result of the modified Euclidean algorithm calculation. An error compensation block(160) compensates for the errors based on a received code word and the determined location of errors and the value of the errors. One or more RAMs(Random Access Memory)(170) store the received code word. A control block(100) determines the number of one or more modified Eculid algorithm blocks and the number of one or more RAMs.

    Abstract: PURPOSE: An error-correction code method using layer modulation and an apparatus thereof are provided to enable variable control of error-correction code rate using layer modulation. CONSTITUTION: An interface unit(310) is input with transmitted-data. The first forward error correction encoder(320) produces first parity bits for forward error correction of the transmitted data by the application of first forward error correction code. A second forward error correction encoder(330) produces second parity bits by applying second forward error correction codes on the transmitted data or the first parity bits. A layer modulator(340) modulates the transmitted-data and the first parity bits into an HP stream. The layer modulator modulates the second parity bits into an LP(Low Priority) stream.
