Abstract A state modulation method and an apparatus for inserting state control codes are provided. To overcome the problems of inefficient control on direct current and low frequency component in conventional state modulation techniques, the disclosed method inserts state control codes in a state modulation method to increase the probability for selection. With multi-level characteristics, the inserted state control codes can provide a plurality of sets of different signals for selection during coding. Thereby, the direct current and low frequency components can be well controlled.
