FDM of VT and VH Signals for EDTV

Abstract

FDM(Frequency Division Multiplex) of VT(Vertical-Temporal high frequency component) signal and VH(Vertical High frequency component) signal for EDTV is described. The FDM is realized by limitting the VT and VH signals in the Vertical-Temporal frequency domain. This method enables us to transmit both VT and VH signals all the time.
