Abstract

This paper proposes the world´s first single-chip 4K 60fps 4:2:2 HEVC video encoder LSI (named “NARA”) with 8K scalability for broadcasting with professional high image quality. It consists of a prediction core with a new prediction mode decision framework, dual coding cores, controlling RISCs, and high speed data buses with multichip 8K configuration, using 28nm CMOS technology. The NARA LSI will lead to a new dimension in future high-quality 8K world.
