    摘要： A video display system that includes a housing has arranged thereon a plurality of video input terminals for receiving a plurality of video signals having different scanning frequencies. An expansion/compression processing circuit replaceably mounted on the housing receives and expands/compresses the plurality of video signals and produces at least one video signal expanded/compressed in synchronism with a sync signal selected by a sync switching circuit. At least one of the video signals is synthesized with another video signal, and the synthesized video signal is produced by a video signal synthesis circuit. A video signal from the video signal synthesis circuit is used to generate a video display signal in synchronism with the sync signal. This video display signal is applied to a display. At least one such video display system, an AV controller, a central control console and a lecture table are combined to realize a screen display system.

    摘要： A display apparatus using a matrix display panel, such as a liquid crystal panel, for converting the number of scanning lines to be displayed to a number that can be accommodated on a panel having a smaller number of scanning lines. The apparatus includes a control circuit which produces control signals in synchronism with the input video signal, horizontal and vertical scanning circuits each including a shift register operated by the control circuit, and a display panel which is formed of a matrix arrangement of pixels that are driven selectively by the scanning circuits. The apparatus further includes a circuit which halts the operation of the vertical shift register at a certain interval within the effective scanning period of the vertical scanning circuit so as to extract vertical shift clocks, thereby removing the vertical shift clocks within the effective display period of the video signal, thereby extracting periodically extracting scanning lines.
