Paper Abstract

The objective of this paper is to investigate the theoretical aspects of colorimetric noise analysis of component video signals for an optical fibre video transmission systems. The design of a low noise optical fibre colour video transmission system requires information regarding the degradation of various hues or at least the colours to which the eye is more sensitive in the presence of system noise. An expression for objective component video signal-to-noise ratio called the Display Signal-to-Noise Ratio (DSNR) is derived for both subcarrier frequency and amplitude modulated systems for the first time. The DSNR expression take into account the effects television receiver decoding and the nonlinearity of the display tube. A fundamental relationship between the input composite video SNR and the DSNR is established. Using this analysis impairments in various hues at different saturations and at different luminances are examined. The effect of the input noise spectrum on displayed primary colours is also analysed. The analysis discussed here is shown to be useful not only for present but also for future video systems and for dynamic noise reduction applications. 337 L
