To Reduce Chrominance Interference in Grey Scale Multi-format Generator by Analyzing and Correcting Signal Waveforms

The basic components of the video signal comprises of Video information, Chrominance level and Sync. Pulses. The Grey scale signals are required to check the compatibility of the display device with composite form of the modern signals, which is affected by chrominance interferences. In this paper, we will analyse the multi format signal generators, which are utilised and has the capability to generate signals, compatible for display inspection of SDTV, HDTV, Monitors display inspections. The major job in display inspection is white balance of the device. White balancing is performed on Monochrome signals which are corrupted by intermittent colour transients. The aim of this study is to reduce the colour transients in Grey Scale signals, by observing the waveforms of Grey Scale patterns, generated by a multi format pattern generator. The analysis of waveforms includes the study of waveforms related to Y/colour difference, greyscale, chrominance, and sync level components.
