Abstract: A visual workstation for use by a viewer includes a dome having an open front end and a truncated spherical inner dome surface. A work surface is disposed in front of and adjacent the dome front end. The work surface defines a viewer area on a side of the work surface opposite the dome. The viewer area is sized and configured to receive the viewer and is positioned relative to the spherical inner dome surface such that the viewer, when located in the viewer area, may view the spherical inner dome surface. A projector is disposed between the viewer area and the dome. The projector is operative to project a truncated spherical projection onto the inner dome surface.

Abstract: A video signal reproducing apparatus for reproducing a video signal recorded on a magnetic recording medium includes a modulating circuit for receiving a color-difference line-sequential signal and modulating the color-difference line-sequential signal at intervals of one horizontal scanning period, an adding circuit for adding a luminance signal to the color-difference line-sequential signal modulated by the modulating circuit, a delay circuit for delaying a signal outputted from the adding circuit or the modulated color-difference line-sequential signal by one horizontal scanning line, and a subtracting circuit for subtracting the signal outputted from the adding circuit and not delayed by the delay circuit from a signal which has been delayed by the delay circuit by one horizontal scanning line. The video signal reproducing apparatus is arranged to provide line interpolation information for the luminance signal as well as simultaneous color-difference signals.
