  10. Is there a name for the method of compressing video signals where the distance
  11. before a certain amount of brightness change is stored, instead of the
  12. brightness at regular points? And, any books/papers/etc about it, especially
  13. relating to astronomical pictures.

  15. Thanks for any help,
  16. Mark Aitchison, University of Canterbury, New Zealand.
