A 9B/10B encoding method is used for encoding a 9-bit source sequence set, including first type, second type and third type of 9-bit source sequence sets, into a 10-bit target sequence set. The first type of 9-bit source sequence set only includes 9-bit source sequences with difference values of 1 and −1. After inserting 1-bit data '0' or “1” in each sequence, each sequence is encoded as a 10-bit target balanced sequence; the second type of 9-bit source sequence set alternatively includes only 9-bit source sequences with difference values of 3 or −3. After inserting 1-bit data “0” or “1” into each sequence, each sequence is encoded into a pair of 10-bit target unbalanced sequences with a difference value of ±2; each sequence in the third type of 9-bit source sequence set is encoded as a pair of 10-bit target unbalanced sequences that are opposite numbers for each other.
