Abstract

A sync signal generating apparatus for use in a converter for converting a broadcast signal between different broadcast systems so as to generate a sync signal adapted for the converted broadcast system. The sync signal generating apparatus includes a first counter for generating various sync pulses using a subcarrier of a selected broadcast system among various broadcast systems as a clock, a second counter for generating an even/odd field detection pulse and various window signals, using an output signal supplied from the first counter as a clock, a first multiplexer for selectively outputting a vertical sync pulse and an equalizing pulse by a window signal, a horizontal sync signal generator for generating a horizontal sync signal having a field identical to that of an externally supplied sync signal, and a second multiplexer for selectively outputting an equalizing and vertical sync signal and a horizontal sync signal by the window signal, thereby generating a composite sync signal, which matches the specification of the selected broadcast system.
