Multimedia systems which began to appear at the end of the 20th century should be in great demand at the beginning of the 21st century. However, multimedia systems, which consist of various kinds of image media such as the existing standard TV (SDTV), high‐definition TV (HDTV), digital TV (DTV), personal computer TV (PCTV), and three‐dimensional TV (3DTV), have been in chaos because various kinds of image formats and scanning methods, such as aspect‐ratio, pixel‐number, field‐rate, frame‐rate, interlaced scanning, and progressive scanning, have been intermingled. To provide for the wide spread of multimedia systems, a newly developed double‐field wobbling display system which uses a scanning conversion technique applied to the various image sources with commonality of scanning, so that compatibility with the conventional TV systems can be realized, is proposed in the paper. The technique makes it possible to display the image sources with an almost fully shared single scanning method without loss of the picture qualities brought by the conventional interlaced and progressive‐scanning system, so that interoperability and high cost‐benefit of the hardware can be secured. Moreover, picture degradations such as vertical response deterioration, line structure, line crawling, and flickering which occur in the conventional display system can be reduced. In this paper, the validity of the display system has been clarified with response analyses of a two‐dimensional spectrum whose variables are temporal frequency and vertical spatial frequency. © 2000 Scripta Technica, Electron Comm Jpn Pt 3, 83(9): 13–22, 2000
