Picture synchronization is indispensable for proper reception in a television system. Complex synchronization signals are transmitted along with the picture information for proper reproduction of the picture at the receiver. A totally different design methodology has been adopted for the generation of complex synchronizing (sync) signals as compared to the one reported earlier, so as to reduce the memory size from 8 K to only 226 bytes. This massive reduction in memory size made it possible to implement the whole design in a highly miniaturized single FPGA. Since the sync signals are complicated, a PROM is used to hold the waveform. In order to reduce the memory size, the basic time durations are chosen judiciously. Moreover, the repeatability of the waveform is exploited by introducing looping in hardware at different places
