- Such things seem to be used partially in a recent proposal for an HDTV
- system called HD-DIVINE, from Sweden. Although there are no detailed
- descriptions, they use 4x2 (v x h) blocks and motion compenastion
- for resulting motion fields. HD-DIVINE is described in the Proc. of
- the Workshop HDTV'92, Kawasaki, Japan, Nov. 18-20, 1992.
