ELM - NTSC Test Signal Generator

From: ELM

A video test pattern generator will be needed when calibrate or test video equipments. To characterize system performance and understnad it quantitative, wave form monitor, vector monitor and related video measurment equipments will be required. Some generic patterns, shch as color bars, cross hatch, dots and full field, are also used for home video creation to calibrate video monitors without any measurment equipment.

This kind of test signal generators for personal use are often found as construction kits, however, most of the kits are designed on cheap analog method and the wave form is not accurate, therefore it cannot be used as a standard signal in fact. I designed and built a digital video test signal generator in order to generate accurate reference signals which can be used for calibration and measurment of video montors and home built video equipments.

Amazing.
