1T-PAL-NTSC is an ultra compact, high performance Standard Converter, converts any of the widely used world television standard signals to any other widely used television standard. In addition to converting between the world's television standards, it also corrects instabilities present in video signals. Time base errors found in videotape playbacks are eliminated and signal amplitude variations are corrected by circuitry that automatically adjusts errant input levels to insure a 1 volt P/P output. Noisy or distorted sync pulses are replaced with reinserted, stable sync. Digital Comb filtering is applied to Y/C signals. Built in AGC maintains 1 V P/P signal outputs.
