ABSTRACT:
A video signal based on an NTSC system is converted into a signal for EDTV. The converted signal is subjected to signal compression in a signal compression ratio of 910/m times. The compressed signal is added with a pedestal level signal and a side level signal. The combined signal is converted into an analog signal, and thereafter primary color signals R, G and B are generated to be imaged on a high resolution television monitor. Thus, the original video of the NTSC system can accurately be reproduced with respect to a high resolution television monitor with an aspect ratio of 16:9.
