Abstract

PURPOSE:To correct error in a color picture easily, by using a data before N- sample in place of data in error for the correction, if incorrectable data appear at a reproducing side. CONSTITUTION:A data selector 2 gives a data to a transmission line 4 and a register PG1 when the data given from a transmission line 1 is not incorrectable, and when incorrectable, the data given to the selector 2 from a register RGn via a transmission line 6 is switched to the transmission line 4 and a register RG1. When a composite color TV video signal is sampled with a sampling pulse having a repetitive frequency N times a frequency fsc of chrominance subcarrier, a data before N-sample is used for the correction in place of the data in error. Thus, without producing error of comparatively eminent color, the correction can be made as the video element with the same brightness as adjacent video elements.
