Abstract
An off-the-air color video recorder employs frequency interleaved chroma and luminance signal information for purposes of bandwidth compression. During playback, a shooting gallery picture defect characterized by motion along horizontal scene edges was noted. Analysis indicated the problem source to be the bleeding of chroma into the playback luminance channel. To avoid this problem, the chroma signal information, prior to recording, has its vertical resolution reduced, e.g., by line-by-line averaging of chroma.
