Super Hi-Vision’ (SHV) is promising as a future form of television. It is an ultra-high definition TV system that has 16 times the number of pixels of HDTV and employs a 22.2 multichannel sound system. It offers superior presence and gives the impression of reality. The information bitrates of the current prototypes range from 24 to 72 Gbit/s, and a fiber(More)
We report a correlation between the dielectric property and structure of stretched poly(lactic acid) (PLA) films, revealed by polarization-sensitive terahertz time-domain spectroscopy and two-dimensional (2D) wide-angle X-ray scattering (WAXS). The experiments evidence that the dielectric function of the PLA film becomes more anisotropic with increasing(More)
NHK (Japan Broadcasting Corporation) is conducting research on the next generation of digital terrestrial broadcasting system to enable large-volume content services such as UHDTV (ultra-high-definition television). In our previous study, we proposed spatially coupled low density parity check (SC-LDPC) codes for broadcasting. The lengths of these codes can(More)
