1. A system for compression and decompression of video images constituted by a stream of composite pixels, each pixel being represented by data of a plurality of luminance and chrominance component types, comprising:

  • block memory means for, during compression, sorting and storing said stream of composite pixels into single-component type data blocks and for providing in predetermined order said single-component type data blocks and for, during decompression, receiving and storing said single-component type data blocks and for reconstituting said stream of composite pixels; and

    means for compressing and decompressing of said single-component type data blocks.
