ABSTRACT:
There is disclosed the use of a beehive cell arrangement of shaped quantization blocks for grouping pixels for the digital approximation of analog video information. A frame may consist of beehive-arranged hexagonal quantization cell blocks or brick-wall-arranged rectangular cell quantization blocks, where each pixel belongs only to one shaped quantization block. A beehive cell arrangement of circle-shaped quantization blocks is described for use when the frame is partitioned into overlapping quantization blocks.
