4K (computer virus)
4k is a computer virus which infects COM files and EXE files. The virus was one of the first to employ stealth tactics. Infected systems will hang, after September 22 every year, which is also the date of birth Bilbo Baggins, a character from "The Lord of the Rings". The code was intended to display the message "Frodo Lives", but hangs in all known variants.
Da Vinci Systems
The da Vinci 2K Color Corrector, manufactured starting in 1998, was a completely revised color correction system that supported HDTV, SDTV, and 2K formats. The later system, the 2K Plus with improved color corrector tools was used on high-end DataCines and telecines like Thomson-Grass Valley's Spirit Datacine and Cintel's C-Reality & ITK Millennium. The 2K operated with a 4:2:2, 4:4:4 or 8:4:4 input in NTSC or Pal. In HDTV it operated with either 4:2:2 or 4:4:4 inputs. Many were interfaced to the Spirit DataCine.
