This paper describes about 525line pro-gressive scan system of EDTVII using 4 : 2 : 2P interface standarlized in SMPTE294M. This system is complied with parallel operation of two-525 interlaced system. Operability of this system is not very much different from conventional composite system. Delay caused by the conversion of the signals is also minimized in this system.

The Virtual Studio System is a joint development project by NHK and Matsushita Electric Indsustrial Co., Ltd. It is installed in Studio CT-415,which is an NHK studio for normal program production. The system produces 3D-CG images which are synchronized with the movements of three television cameras (panning, tilting, zooming and focusing), and composites CG images with studio blue screen images of the performer by using Chromakey with 3D-depth. From September 1996,NHK Production Operations Center has started wide use of this system to produce programs. This paper explains this system and its use in program production.
