This paper describes a study and computer simulation of a high-definition codec for non-interlaced 525-line (525/1:1) signals. It has been proposed that 525/1:1 signals be used in production systems for future high Picture quality television broadcasting in Japan (EDTV2). This makes high-efficiency 525/1:1 digital compression techniques vital. This experiment investigates the relationship between bit rate and picture quality after compression/decompression, using an experimental codec model and 525/1:1 test sequences for evaluation prepared for this research. Toe results verify the feasibility of a 525/1:1 codec providing primary-distribution picture quality using picture rate of 35 to 50 Mbps.
