Encoder for 8K "Super HI-Vision" Developed
Mitsubishi Electric Corporation and NHK, Japan's national public broadcasting organization, have developed the world's first HEVC (High-Efficiency Video Coding) encoder for 8K ultra HDTV "Super Hi-Vision" (SHV).
Dubbed as the broadcasting medium of the near future, SHV features 16 times the number of HD pixels and a 22.2 multichannel surround sound experience.
HEVC, which offers roughly double the data compression of AVC2 and about four times that of the MPEG-2 standard currently employed for digital HDTV broadcasting, is set to be adopted as an international standard this year.�
The high-volume SHV images are divided 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 Electric Corporation are pursuing research and development of real-time coding of the 120 Hz frame frequency of SHV.�
