Filed: 1998-12-19
Abstract: PURPOSE: A generator of reset signal is provided to prevent a mis-operation of a system after converting from a recording mode to a playing mode or from the playing mode to the recording mode in a DVHS(digital video home system). CONSTITUTION: A counter generates a count signal by receiving a clock signal and an outer reset signal and by receiving a mode signal, desirably a first mode signal, a second mode signal or a third mode signal corresponding to each a recording, a standing-up or a playing mode. When the count signal is 0 or 252, a generating unit of inner reset(20) generates an inner reset signal of low level and generates the inner reset signal of high level in the rest section.
