| Outline of Final Research Achievements |
In this study, I designed streaming technologies (video compression, transmission, and restoration technologies) to achieve high-quality wireless network transmission of multidimensional video, which is one of the most urgent technologies for realizing wireless immersive systems. Specifically, I developed (1) a compression technology for multidimensional video, (2) a multidimensional video transmission technology to cope with fluctuations in wireless network quality, and (3) a multidimensional video restoration technology to cope with quality degradation due to errors and losses caused by the networks, respectively. I have proposed a basis of streaming technology that can provide high-quality multidimensional video according to each user device's instantaneous radio propagation environment.
