METHOD FOR COMPENSATING SYNCHRONIZING SIGNAL IN TELEVISION

摘要

PURPOSE: A method for compensating a synchronizing signal in a television is provided to display a stable image screen regardless of a receiving state of a broadcast signal by generating a stable pseudo vertical synchronizing signal having a stored frequency. CONSTITUTION: A microcomputer enables a user to receive a broadcast signal(200). A vertical synchronizing signal is separated from the broadcast signal to be applied to the microcomputer(202). The microcomputer detects a frequency of the separated vertical synchronizing signal(204). A microcomputer judges whether a frequency(B) of a stable vertical synchronizing signal is out of a predetermined range in a frequency(A) of a stable vertical synchronizing signal(216). If the frequency(B) is out of the predetermined range compared to the frequency(A), a pseudo vertical synchronizing signal is generated.
