<p>A video signal recording apparatus comprises a sampling circuit for sampling an input video signal by a signal having a predetermined frequency fs, a circuit for obtaining a multiplexed signal by multiplexing a reference burst signal to the output sampled signal of the sampling circuit, and a circuit for recording the multiplexed signal on a recording medium. A video signal recording and reproducing apparatus comprises in addition to the constituting elements of the recording apparatus, a circuit for reproducing the recorded multiplexed signal from the recording medium, a circuit for obtaining from the reproduced multiplexed signal first and second reproduced sampled signals having a relative time difference of one horizontal scanning period, a circuit for generating first and second sampling pulses having the same frequency fs and having phases which mutually differ by 180 DEG , a circuit for re-sampling the first and second reproduced sampled signals by the respective first and second sampling pulses so as to obtain first and second re-sampled signals, and a circuit for at least adding the first and second re-sampled signals so as to obtain a reproduced video signal.</p> |
