Outline

We are developing wireless link systems for live 8K program production. This exhibit introduces a real-time 8K transmission system that uses high-capacity microwave/millimeter-wave FPUs^※1 and an encoder and decoder based on the highly efficient HEVC/H.265^※2 video compression method.

Features

Microwave-band FPU

By improving the spectral efficiency over the same 18-MHz bandwidth as an HDTV FPU in microwave bands (6/6.4/7/10/10.5/13 GHz bands), we have achieved long-distance transmission with a capacity of approximately 200 Mbps. We are also contributing to the development of Ministerial Ordinances and the standardization.

Millimeter-wave-band FPU

In the millimeter-wave bands (42/55 GHz bands), we utilize a wide bandwidth of 125 MHz to implement medium- and short-range transmission at speeds of approximately 400 Mbps. In March 2017, this method was reflected in a revision to the standard (ARIB STD-B43).

8K HEVC encoder/decoder for transmitting video footage

We have developed an encoder and decoder for video footage that can perform encoding and decoding of 8K video in real time using the HEVC/H.265 compression method at a high rate of approximately 200 Mbps. This will enable 8K transmissions through FPUs, communication satellites, and IP systems.
