In a joint exhibit booth with the Japan Electronics and Information Technology Industries Association (JEITA), we introduced methods and equipment required for receiving and viewing Super Hi-Vision broadcasts (which are sched- uled to begin in December 2018 as a regular service) at home. Furthermore, to showcase our latest 8K program-production technologies, we exhibited the 8K OB van including a double- speed slow-motion system utilizing high-frame-rate production equipment at 120 Hz developed by STRL. These technologies enable a variety of video representations. Moreover, in the area called INTER BEE CONNECTED, which introduced the latest trends in collaboration between broadcasting and communications, we displayed Hybridcast Connect X -a basic technology for linking broadcast services and IoT devices. We introduced an example of how viewers can experience a new way of enjoying programs by connecting de- vices such as robots and lighting to their TV. In the area called INTER BEE IGNITION, which intro- duced new image-expression technologies, two developed ap- plications were exhibited: a virtual art museum-in which paintings can be arranged in a virtual space and viewed freely on 8K monitor, and a pop-up picture book-created by integral 3D technology, enabling natural 3D images to be seen with- out special glasses. In the virtual art museum, by employing a technology for outputting and displaying 8K video images from a PC, a masterpiece can be viewed close-up in ultrahigh- definition images. We will continue our efforts to introduce our R&D results to many people. Appearance of the NHK/JEITA booth Exhibition of Hybridcast Connect X Exhibition of virtual art museum
