Paper Abstract

For analog color television standards such as PAL and NTSC, the transmission of color (C) takes place within the band available for the luminance (Y). At the television receiver, the required separation of Y and C can only be imperfect as both components now share the same frequency space. Modern televisions apply so-called comb-filters that exploit the opposite sub-carrier phase of correlated samples to separate both components. However, cross-talk artifacts and loss of resolution will occur in situations where no sufficiently correlated samples meet the strict opposite phase requirement. In this paper, a novel Y/C separation method is presented that is able to use samples with non-opposite sub-carrier phases.
