Research and Development on a Mobile Wireless Link System for Ultra High Definition Broadcasting Program Contribution

Abstract

The authors are conducting research on a next generation mobile Field Pick-up Unit (FPU) system that enables wirelessly relaying ultra-high-definition video materials such as road race broadcasting programs. We are working on increasing the capacity by 4×4 TDD-SVD-MIMO technology that adaptively controls transmit parameters depending on channel conditions. We are also researching on frequency sensing technology and variable rate video coding technology toward realization of mobile relay of 4K/8K program materials. In this paper, we report on the outline of the proposed system and the technologies which build up the system.
