I am posting this for a friend who does not have access to the net. Please
send e-mail replies to me and I will forward it to him.

  I am in need of a subroutine in C or Fortran (mathematical expression would
  be sufficient) to convert digitized NTSC signal to either YIQ or RGB signal.
  The NTSC was sampled at 4 times the sub-carrier frequency and has values 
  from 0 to 255; alternate lines are 180 degree out of phase. Any information
  or reference to book, paper concerning this would also be appreciated.

  Thank you.
