Abstract
A storage and interpolation device for digital television pictures having a memory organized in `tiles` of memory elements (2). Sub-assemblies of tiles (2A, 2B, 2C, 2D) all have the same coordinate address in one coordinate direction and have outputs coupled to an interpolation filter (6) operative in that direction. Individual tiles (2A; 2B; 2C; 2D) of respective sub-assemblies (1A, 1B, 1C, 1D) all have the same coordinate address in the other coordinate direction and the outputs of the filters (6) of the sub-assemblies are connected to inputs of a further filter (9) operative in the other coordinate direction. By allocating pixel values of discrete image areas of the picture to respective sub-assemblies (1A, 1B, 1C, 1D) in the horizontal direction and to groups of tiles (2A, 2B, 2C, 2D) in the vertical direction, interpolation can be effected by addressing all tiles simultaneously to produce a corresponding output from the filter 9.
