概要	To help pave the way for Super Hi-Vision (SHV) broadcasting, we have developed a new codec system that can encode and decode SHV signals in real time. This is the third generation of SHV real-time hardware codec. This efficient compression system maintains high picture quality by using eight 1080/60p (60 frames/s) encoding units and a video format converter with signal compensation processing that takes the properties of the Dual Green format of SHV into account. The video format converter divides an SHV image spatially into eight 1920 x 1080 portions, each of which is fed to the encoding unit. In the previous SHV codec, the SHV image was divided into 16 portions (spatially eight and temporally two) and 16 1080/30p encoding units were used. Compared with the previous system, the new codec achieves a 50% bitrate saving and downsizes the codec by almost half.
