PURPOSE:To drastically reduce the capacity of necessary memory by providing time-differences between respective color signals R, G, and B then A/D converting them at the time of recording, and providing time differences that are inverse to the said ones between the D/A converted signals R, G, and B at the time of reproducing. CONSTITUTION:Among the signals outputted from an RGB demodulator 1, R-signal is directly inputted to an A/D converter 2, G-signal is delayed for a time tau by a delay circuit 20 then inputted to an A/D converter 3, and B-signal is delayed for a time 2tau by a delay circuit 21 then inputted to an A/D converter 4. The signals are A/D converted with a sample clock whose frequency is one third of normal frequency in the converters 2-4, and respectively stored in RAMs 10-12. The R-/G-/B-signals read out from the RAMs 10-12 are D/A converted by D/A converters 5-7, then provided with the time-differences inverse to those at the time of recording by delay circuits 22 and 23, and supplied to a display 8. As a result, in the display 8, the R-/G-/B-signals are sequentially and repeatedly displayed on one horizontal scanning line.
