Video signal data recoding method for standard memory components and apparatus for perfomring the method

Circuit configuration for storing video signal data of at least a partial frame in standard memory components having 2.sup.m possible memory addresses, comprising:

• 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 for assigning picture addresses to video signal data and controlling memorization of the video signal data, said control device having picture address terminals carrying picture addresses with separate x address bits for pixel addressing and y address bits for line addressing;
• a recoding apparatus connected between said picture address terminals and said memory address input terminals for uniquely assigning each picture address its own memory address;
• and
• means for reading out video signal data from said memory device.

Method for storing video signal data of at least a partial frame in standard memory components, which comprises providing standard memory components with 2.sup.m possible memory addresses;

• addressing b pixels with x address bits through picture addresses;
• selecting b<2.sup.x ;
• selecting z<2.sup.y ;
• selecting m, b, z, x and y as positive integers;
• selecting 2.sup.m as small as possible but greater than the product of b and z;
• recoding a address bits of the x address bits and r address bits of the y address bits into p address bits of the memory addresses utilizing bit combinations not occurring in the picture addresses for uniquely assigning each occurring picture address its own memory address, and selecting:
• s<x and r<y and p<s+r and selecting s, r, and p as positive integers.
