We investigated the relationship between eye-position distribution and head-orientation while viewing dynamic images in an 85 inch 8K ultrahigh-definition television (UHDTV). Participants watched video clips of several types of scenes made for UHDTV without any restriction of head movements. The result showed a correlation between eye and head orientation, which is similar to the coordinative movements of the eye and head for static-image viewing in previous studies. The distribution of eye positions was biased in the direction of head orientation both in horizontal and vertical directions. When the head orientated to the left/right (or up/down), the eyes also tended to direct in the left/right (or up/down) relative to the head. These findings suggest that eye-head coordination is similar between static and dynamic images and that head orientation could be used to evaluate the viewing condition and image contents of wide field of view display such as that of an UHDTV.

We report on the recording characteristics of a near-field optical recording thin optical disk (NFR-TOD). We proposed a new cooling-less-type write strategy for recording, applied it to the NFR-TOD experimental system, and also applied a partial response maximum likelihood (PRML) signal processing, which was evaluated and optimized the PR coefficient for playback signals of the prototype NFR-TOD. The NFR-TOD has a track pitch of 160 nm and improved recording characteristics. The experimental results of the prototype NFR-TOD and the system indicate sufficiently low bit error rates (bERs) for recorded data at a fourfold higher recording density than the current Blu-ray disk.

“…These pixel-based systems are developing toward those with more pixels. This trend is exemplified by super high-definition TV (S-HDVT) [1] or ultra-definition TV (UDTV). Although UDTV has more than 100 times the pixels of SDTV (standard-definition TV), the number of views is still single.…”

FTV (free-viewpoint television) is an innovative visual media that allows users to view a three-dimensional (3D) scene by freely changing their viewpoints. Thus, it enables realistic viewing and free navigation of 3D scenes. FTV is the ultimate 3DTV with infinite number of views and ranked at the top of visual media. FTV is not a conventional pixel-based system but a ray-based system. New types of ray capture, processing, and display technologies have been developed for FTV. These technologies were also used to realize an all-around ray-reproducing 3DTV. The international standardization of FTV has been promoted in MPEG. The first phase of FTV ismulti-view video coding and the second phase is 3D video. In this paper, the FTV system and its technologies are reviewed.
