DIFFERENTIAL CODING AND DECODING METHOD AND RELATED CIRCUITS

摘要

A method for the differential coding and decoding and related circuits are disclosed here. The differential coding is a special type of coding which, instead of coding directly an input signal, carries out the difference between this signal and a predicted signal of it. This allows the reduction of the information to be transmitted. The invented method is capable of further reducing the signal redundancy and therefore the information to be transmitted.
