  12. Thank you for all of your notes.
  13. The quickest solution came from J. Eliot B. Moss of Carnegie
  14. Mellon U.
  15. He suggested to simply XOR the records, then remove the zero
  16. results.
  17. So I simply XOR-ed the current record with the new record, 
  18. producing a new record, then applied RLE against that record.
  19. The size is quite small, and it is relatively fast.

  21. Thank you for all your help.
