Noise reduction in a digital HDTV system

HDTV cameras show less signal-to-noise ratio than common TV studio cameras because of the high bandwidth of HDTV signals. It is necessary to reduce the noise in a high quality HDTV system. A new noise reduction method was developed at the Heinrich-Hertz-Institut Berlin. This noise reduction works in motionless and motion parts of the picture without subjective visible degradations. The conversion of this motion-adaptive algorithm for noise reduction into a hardware structure and the simulations of this structure are described. The development of the hardware structure took available integrated circuits into consideration.
