Document Type and Number:
Japanese Patent JP3496828
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a coding and decoding method and system that can efficiently transmit digital information of a huge amount with high reliability.
SOLUTION: A data transmission period 20 is divided into a plurality of slots 22-38, a data bit and check bit stream is inserted to the given slots 22, 26, 30, 34, a complementary bit stream to the data bits and the check bits is inserted to the lots 24, 28, 32, 36 just after the given slots 22, 26, 30, 34 and the final slot 38 of the data transmission period 20 is used for a separation protection slot of the data transmission period.
