An apparatus and method for acquiring and storing video picture frames at a first rate and for reading and displaying said frames at a second rate which is a selectable integral of the first rate implements the steps of: converting analog picture elements to digital words, storing at least one frame of digital words in a first memory at the first rate, reading the frame of digital words out of the first memory at the first rate in interlaced scan format, storing the frame of digital words read out of the first memory in a second memory at the first rate, reading said frame of digital words out of the second memory at a second rate which is a selectable integral multiple of the first rate, converting the digital words read out of the first memory to analog picture values and putting out said converted analog picture values in interlaced scan format, and converting the digital words read out of the second memory to analog picture values and putting out the converted analog picture values at the second rate.
