The EMC World Cup Golf Tournament was held at the Gotenba Golf Course of the Taiheiyo Club in Shizuoka, Japan from November 15th to 18th, 2001. As the host broadcaster, NHK produced the international signal of the event in HD/SD format, distributed it to many countries worldwide, and broadcasted it live through terrestrial TV, satellite TV, and HDTV. NHK also initiated a new data broadcasting service that provided real-time information about the players. This paper describes the technical features and problems encountered in producing the large-scale HDTV live coverage of the event.

Realistic virtual characters generated by computer graphics are increasingly required in broadcasting programs. We propose an algorithm that implements interactive, real-time motion generation for the creation of virtual acrobats that perform complex circus acrobatics using a motion generation engine to support production. To facilitate control, we designed a graphical user interface and a minimum set of inputs which give a very effective result in motion. For fast computation, we designed each character and other objects with minimum dynamics construction to perform each motion. Because a circus acrobat usually requires large space, the motion capture system cannot be used. Furthermore, traditional key-frame animation cannot apply the external forces that are important to the motion. To solve these problems, our algorithm uses dynamics simulation and is able to create a variety of motion.

We developed software for the non-linear editing of stereoscopic 3-D movies. This software has functions unique to stereoscopic 3-D movies and works on a personal computer. Editing is much simpler with this software than it is with conventional systems that require four synchronized video tape recorders. At the same time, the software makes possible the post-recording adjustment of field-sequential 3-D movies, a difficult task for conventional editing systems. In addition, the results of the usability test confirmed the software's ease of use and enhancement of editing tasks.

We propose an educational broadcast service that supports not only passive learning by simply watching broadcast programs but also active learning in which students search for and collect programs for their own purposes, such as making presentations, and exchanging opinions. To achieve this new broadcast educational service, we have constructed an education support system that enables users to search multimedia databases using agent technology. The system assumes its users to be elementary and junior high school students and supports theme-based “investigative learning.” This paper describes the features of this system and presents a system overview.

This paper proposes a retrieval mechanism for a peta-byte video archive equipped with a large-scale, automatic, tape-feed robot. The mechanism has a multiple video digest display system with a user-friendly interface and a scene-detection-based index allowing users to efficiently access the detailed video information. An effective integrated system for managing different types of servers that are set up to maximize the performance of such a large-scale archive is also discussed. Our verification tests show the effectiveness and the feasibility of the proposed solution.

We developed a video archiving method using MPEG-7 description for both retrieval and editing. When using an MPEG-7 description, only one MPEG-7 instance can cover the area from retrieval to editing. A key frame and a headline can be used for retrieval. With editing, an original time code, taken at the time when recorded or registered, can be used to construct an edit decision list (EDL). This EDL can be used wherever the archived video is available. This paper describes the method and includes examples of an MPEG-7 description of a genre dictionary, a content ID, a key frame, a headline, and an original time code.

Stereoscopic displays that produce multiple viewpoint images, such as multiocular image sequences, have been developed in recent years. These displays provide motion parallax as a depth cue. The present study was conducted to examine if the cardboard effect, i.e., the visual distortion observed in conventional binocular stereoscopic displays, is improved by motion parallax. Column images that show the cardboard effect were displayed to subjects. The subjects were instructed to adjust the curvature of a plane half circle to quantify the curvature of the displayed column. For motion parallax, the presence or absence of motion parallax, the presence or absence of head movement, and the velocity of the column were set as variables. For binocular disparity, the magnitude was set as a variable. The results showed that the cardboard effect improvement rate under the condition that allows subjects to operate both motion parallax and binocular disparity was higher than that under the condition that allows subjects to operate only binocular disparity. No marked effect by the presence or absence of head movement or the difference in velocity of the column was observed. These results suggest that motion parallax, which is reproduced in multiple viewpoint stereoscopic displays, improves the cardboard effect.

Electro holography using LCD panels or AOMs is one of the techniques that can be used in 3D animation. The technique of using a light extracted from a white light laser or a white light source was developed asa way of using electro-holography in color reconstruction. However, it is difficult to adjust the image position of the RGB bands, because of the many focal lenses were used in real image reconstruction. Having said that, when using virtual image reconstruction, it is possible to remove the focal lenses. This is considered a simple optical setup. In this paper, we will examine a the simplification of an optical system in virtual image reconstruction.

A new technique is proposed which enables the construction of an auto-stereoscopic display which can generate a number of horizontal parallax images simultaneously. A number of telecentric optical systems are arranged in a modified two-dimensional array and multiplexed. Because each optical system has a different horizontal position, each parallax image generated by each optical system is displayed in a different horizontal direction. The difference in the vertical display direction due to the optical system's vertical position is canceled by a vertical diffuser. This display enables the observation of 3-D images simultaneously without the use of 3-D glasses. Observers can perceive 3-D images with binocular disparity, vergence, and motion parallax. In addition, accommodation may work, because a number of parallax images are displayed with a very small horizontal angle pitch. There are two types of configurations that can be used in an auto-stereoscopic display; one uses multiple afocal imaging systems, and another uses light source arrays. An auto-stereoscopic display having 64 parallaxes is constructed using the former configuration.
