Colorimetric noise analysis of an optical fiber video transmissionsystem

The theoretical aspects of colorimetric noise analysis of an optical fiber receiving system for multichannel television signals is investigated. The effect of display tube nonlinearity on the optical front-end receiver noise is discussed, and an expression for display signal-to-noise ratio (DSNR) is derived. A relation between the standard International Radio Consultative Committee (CCIR) SNR and the DSNR is established. This is used to analyze the displayed picture quality quantitatively in terms of various hues of different saturations. The way in which the displayed picture quality can change under different luminances, is shown
