Abstract
In a signal coordinating method and apparatus, a pulse generating circuit receives a VSYNC signal and generates a plurality of critical pulses that define critical time periods from fields can control edges of the VSYNC signal. A determining circuit receives an HSYNC signal and the critical pulses, and generates a trigger signal upon detecting that a line scan control edge of the HSYNC signal appears during one of the critical time periods. A time delay loop introduces a time delay into the VSYNC signal upon receipt of the trigger signal to cause the critical time period to appear after the line scan control edge of the HSYNC signal.
