Compression and decompression of video image data involves removing data ( 230 ) representing pixels from a field to leave data representing pixels adjacent and on both sides of the removed pixels in at least two directions. Different pixels are removed from different fields so that over a given number of consecutive fields, there is remaining data representing all the pixels. For decompression, interpolation ( 250 ) uses a statistical combination of the remaining data representing the remaining pixels on both sides in the two directions, and uses remaining data for a corresponding pixel from a different field. Such decimation can retain more information, and statistical interpolation can enable data reconstruction with fewer artifacts and less blurring of edges and lines, without heavy processing requirements. The interpolation can be motion sensitive. The chrominance can be decimated to a lower resolution and/or coarser quantization level.
