JPS6460077A - Video signal reproducing device - Google Patents

Abstract

PURPOSE:To prevent the generation of an area in which the contents of a memory are not rewritten and to improve the picture quality of a reproduced picture at the time of a high speed reproduction by flowing the position of a noise bar in a constitution in which a writing to the field memory is prohibited when a reproducing signal level is below a prescribed value at the time of the high speed reproduction. CONSTITUTION:Means 16, 45 for changing the position of the noise bar generated at the time of passing through other track during the high speed reproduction, a detecting means 21 for detecting that the reproducing signal level is above the prescribed level, a digital memory 13 and a memory control circuit 14 for prohibiting the writing to the digital memory 13 of a reproduced signal corresponding to the noise bar by the output signal of the detecting means and sequentially reading the contents of the digital memory 13 asynchronously with the writing are provided. Thereby, the position of the noise bar is passed without fixing the position of the noise bar at the time of the high speed reproduction to change the area in which the field memory 13 is rewritten, prevent the generation of the rewriting is not executed and prevent the deterioration of the reproduced picture.
