| Abstract: |
The Super Hi-Vision (SHV), which is an ultrahigh-definition video system with 4000 scanning lines, has been developed by NHK. The video format of the SHV comprises 7,680 × 4,320 pixels, which is 16 times the total number of pixels of an HDTV and the frame rate is 60 Hz with progressive scanning. It has been designed to give a strong sensation of reality to viewers. However, in order to make the system suitable for practical use such as broadcasting services, a new compression coding scheme is necessary for high-efficiency transmission. Therefore, we have developed a Super Hi-Vision Codec system based on MPEG-2 and AVC/H.264 video coding standards. SHV video signals are converted to sixteen HDTV signals and each video signal is processed by HDTV codec. In this paper, details of this codec system are described and some transmission experiments using the codec are introduced. |
