Abstract

A synthetic motion signal was previously proposed to perfect proscan conversion (see N. Suzuki et al., J. ITE, vol.42, no.9, p.966-972, 1988). Good conversion characteristics were obtained without any modification of current IDTV (NTSC) receivers, and new standards were not required. This signal was found to be only slightly visible in highly saturated image areas. An improved multiplexing method is proposed for reducing the disturbance caused by the synthetic motion signal, especially in such areas. This is accomplished by adding the signal to a linear main signal. Hence, the synthetic motion signal does not leak to other components on the display, and disturbance is minimized. Subjective assessment showed that this method is clearly effective
