Abstract

PURPOSE: To satisfy the compatibility between an NTSC system and a high definition television system by allowing a high definition television signal to be inputted to a field memory used for the system processing the signal of the NTSC system by means of a non-interlace scanning.
CONSTITUTION: The field memories 13, 14 are used for the non-interlace system of an NTSC signal. A write/read control signal R/W from a control circuit 19 brings one of the field memories to the write state and the other to the read state, the timing decides a vertical display position (n) also so as to form the write/read state of the signal from the (n)-th line to the (n+525)-th line and from the (n+563)-th line to (n+1088)-th line. A clock switching circuit 20 is controlled by the control signal R/W and inputs a clock fc to the field memory in the write state and a clock fc' to the field memory in the read state. That is, the memories 13, 14 are set alternately to the write state in synchronizing with the 1125- line system and the read state in synchoronizing with the 1053-line system.
