TAO has carried forward the Research for producing Technology of less-tiredness 3D-vision program, for seeking 'Gentle 3D-vision for Human'. In the research, we have studied more suitable arrangement of several switching system cameras, when shooting 3D program on the Stage. Finally we've got the best condition of the cameras that enables us to reproduce the near Real-Space.
In march of 1997,we broadcasted the total eclipse of the sun live from Mongolia with the latest technology. Despite of terrible weather the actual shooting was successfully done up in the air with the helicopter camera. In the midst of the black-faced sky was the beautiful "Diamond Ring" we could see very clearly. The world-widely controversial comet "Hale-Bopp" was captured by the all new ultra high sensitivity HDTV camera just mysterious as it was.
We have succeeded in developing a Superimpose System for portable computer. Not only showing superimposition and "Telop", as a main function, we are able to show moving superimposition, make super easily. Also this new system has "Sportscoder" function.
CCD defects often appear in CCD cameras as flaws on fixed points in the picture with a constant brightness. Among these defects "White Defects" have high brightness levels which stand out in dark scenes. Because this considerably ruins the picture quality, it proves to be a big problem. This device automatically detects and corrects CCD defects which occur during camera shooting, by using a filter and pattern recognition technology. It can correct multiple white defects at one time, therefore it can reduce the time needed for corrections in post production.
The number of requirements by TV program producers for novel and attractive productions have been increasing. In this paper, we describe the present situation of three dimensional computer graphics production in TV broadcasting programs, based on our recent CG production work. We also discuss the future prospects of 3D-CG production regarding to hardware/software system and necessity of fostering new skills and talents for the CG production.
EDAS (Entry Data Announce System) is a support system for operations. This system automatically warns the workers it is time for program transmission and also informs the operator of some problem with the broadcast devices by a vocal announcement and LED indicator board, which operates based on the E-81 operating systems.
This system based on Macintosh can work on-line and manage effectively the broadcasting equipment for program production. Main functions of this system are equipment database, equipment allocation database, allocation schedule display and comunication among terminals.
At low level electric field midium wave broadcasting reception extremely gets worse by the interference of foreign midium wave reflecting from ionosphere. This time we make a trial device that remove foreing midium wave for the improvement of midium wave reception stuation.
This paper presents the novel method of automatic calculation for estimating the television broadcast service area and the electric field intensity distribution. The numerical calculation of diffraction loss used altitude mesh data and is consider to the curvature for a spherical surface of the earth. The computer simulation shows that this method is effective to estimate both the analog television broadcast and the digital television broadcast.
