Apparatus for storing a plurality of fields of digital video signal where each field consists of a plurality of n-bit words and n may vary downwards from a maximum value, comprises circuits for arranging the n-bit words of each incoming field in n bit-planes, each bit-plane containing a respective bit from each n-bit word, a video signal store comprising a plurality of memories each capable of storing the bits of a bit-plane, a common data bus for supplying the bit-planes to the memories, and circuits for controlling writing of the bit-planes in the memories such that a first field is written in a first n of the memories, the next field is written in a second n of the memories, and so on until all memories have been written in.
