ABSTRACT:
A picture transformation memory has three field stores which rotatively store a next field of video data, output a prior field of video data and output a current field of video data to provide a full frame output for each field input period. Each field store has four planes which contain identical fields of data and are read from sequentially pixel by pixel. Each plane has four banks with the field data being read into the banks sequentially pixel by pixel such that when one pixel is addressed, a local address generator addresses the neighboring pixels as well to produce a multi-pixel output to an interpolator. Four half bandwidth data the first and third planes contain identical data and the second and fourth planes contain identical data in the same address locations as the corresponding data in planes one and three. The planes are independently addressable as are the pixels in each plane so that the pixels can be read from the picture transformation memory in a random sequence to accommodate any desired picture transformation.
