-23- METHOD AND SYSTEM FOR IMPROVED RECONSTRUCTION OF VIDEO IMAGES IN LINE SEQUENTIAL CHROMA FORMAT ABSTRACT A method and system for reconstruction of chroma component segments in a line sequential chroma format television system. Filtering of a received line sequential chroma signal is employed to reconstruct missing chroma components and to attenuate phantom fre- quency components greater than one half the spatial sampling rate. Digital and analog filters are dis- closed for implementation of such post filtering. The luminance component of the line sequential signal is delayed at the transmitter to synchronize the recon- structed chroma segment with its corresponding lumi- nance segment with the use of minimal hardware at the receiver. Horizontal offset chroma sampling is used along with such post filtering to decrease transmission bandwidth requirements without sacrificing horizontal resolution at the receiver.
