Development of Millimeter-wave Link for 8K Super Hi-Vision Program Contribution

摘要

We have developed a millimeter-wave-band 4K/8K FPU having a maximum transmission capacity of 600 Mbps for transmitting 4K/8K program contributions such as program for news and sports relay broadcasts over wireless links. It was shown by an outdoor transmission experiment that the FPU can be used for 8K program contribution over an 8 km wireless link. On the basis of link budget, this millimeter-wave-band 4K/8K FPU is expected to be capable of transmissions at a distance of approximately 50 km under fair weather conditions and about 5 km under rainfall of 20 mm/h. In the future, we plan to conduct long-term transmission experiments, test transmission characteristics under rainfall, and make upgrades toward stable operation with the goal of putting this millimeter-wave-band 4K/8K FPU to practical use in 4K/8K program production.
