NTV has succeeded to be the first in Japan to produce programs all done in computer graphics. The four experimental programs entitled "CG Drama series" (each 30 minutes) are works of April, 1995. The latest computerized system was oriented and a newly developed techique enabled efficient visualizing of high quality CG. The optical motion capture system as well as the magnetic motion capture system of 1994 are some of the noticable skills that supported the production. Its high performance recieved wide attention and is sure to be applied to future software production of the multimdia era.
MIYAGI Television Broadcastins Co., Ltd. is proud to announce the inauguration of its new nonlinear editing and telecasting system. to coincide with the refurbishing of its studios for primary and peripheral news. With the nonlinear system, a server stories video and audio programs, and then, via an optical LAN with an ATM switching system, sends them to independent terminals for editing and telecasting. The first of its kind in Japan, the integrated system enables staff to preview and/or telecast programs in real time after editing. Its principal application is to primary news programs, as well as to "peripheral information" programs such as event announcements, program publicity spots, etc.
The serial digital video can be multiplex transmitted various kinds of communication data by using ancillary data space that already utilizing digital audio. If the ancillary data space will be supplied to the transmissin of images. It's possible trasmitted various information such as tally information, cameraman title name, camera No-title, video source and etc by along with only one video signal, (It is not necessary such as auviliary signal cable.) It's discuss to practical use on this by user and manufacturer. But, we developed our own incorporating this processing for the digital component video systems.
In the contribution of high quality video sources, such as EDTV-I, the conventional FPU can transmit only 4.2MHz horizontal frequency band width. Especally for squeezed mode programs, only three fourths of horizontal band width of conventional NTSC's band width is obtained when EDTV-I encoding (4-3 conversion) is carried out. In this paper, we report a new FPU that transmit 6MHz horizontal band width of EDTV-I video signals including its experimental system and investigation.
