Abstract
The authors discuss the problems of sequential scanning and present a 4-channel camera-system which avoids these problems. A signal format for storing sequentially scanned HDTV signals without exceeding the bandwidth of commercially available VTR's is proposed. This format uses diagonal frequency shaping followed by a line quincunx subsampling structure.
