Tosynchronize converted input signals and unconverted inputsignals, it is possible to delay the unconverted input signal.For details, 1 “To delay unconverted input signals(frame delay function)” (p. 315).Conversion format combinationsThe combinations of switcher signal formats andsupported format converter formats are as follows.Signal format Input reference signalTri Sync BB1080i/59.94 59.94 Black Burst59.94Sync 59.941080i/50 50 Black Burst 50 Sync 501080PsF/24 48 –1080PsF/23.976 47.952 –720P/59.94 59.94 Black Burst59.94Sync 59.94720P/50 – Black Burst 50 Sync 50
