NHK & Mitsubishi unveil world’s first encoder for 8K Super Hi-Vision

NHK and Mitsubishi Electric Corporation have jointly developed the world’s first HEVC encoder for 8K ultra HDTV Super Hi-Vision (SHV).

HEVC is due to be recognized as an international standard this year. It offers about double the data compression of AVC2, and almost four times that of the MPEG-2 standard currently employed for digital HDTV broadcasting.

The encoder divides High-volume SHV images into 17 horizontal rows. The parallel processing of these rows makes it possible to achieve real-time coding of SHV images. The deterioration of picture quality at the row boundaries has been lessened by having rows share data concerning the speed and direction of moving objects.

NHK and Mitsubishi are now pursuing the research and development of real-time coding of the 120 Hz frame frequency of SHV.
