Abstract
A method for storing video signal data of at least a partial frame in standard memory components includes providing standard memory components with 2.sup.m possible memory addresses, addressing b pixels with x address bits and separately addressing z lines with y address bits through picture addresses, and selecting b<2.sup.x, z<2.sup.y, and m, b, z, x and y as positive integers 2.sup.m is selected to be as small as possible but greater than the product of b and z. The x address bits and y address bits are recoded utilizing bit combinations not occurring in the picture addresses for uniquely assigning each occurring picture address its own memory address. A circuit configuration for performing the method includes a memory device having memory address input terminals for addressing 2.sup.m possible memory addresses, a data input terminal, and a data output terminal. A control device assigns picture addresses to video signal data and controls memorization of the video signal data. The control device has picture address terminals carrying picture addresses with separate x address bits for pixel addressing and y address bits for line addressing. A recoding apparatus is connected between the picture address terminals and the memory address input terminals for uniquely assigning each picture address its own memory address. A device is provided for reading out video signal data from the memory device.
