A study of digital Y/C separation in NTSC or PAL color television
S.-E. Ito · IEEE Transactions on Consumer Electronics · 1994
It has been considered very difficult to perform digital Y/C separation of NTSC or PAL signals completely because Y and C signals occupy accurately the same spectrum under 2 or 1 dimensional certain conditions. This paper examines the conditions about the three-dimensional digital Y/C separation filters and scene change detectors to control these filters for more complete Y/C separation.>
