In a video signal transmitting device, a basic image generation unit extracts, for each of the color signal component, pixels constituting a frame of the color signal component at a uniform interval two-dimensionally and two-dimensionally arranges the extracted pixels in a prescribed arrangement to generate a prescribed number of color signal basic images. A basic stream generation unit extracts, for each of the color signal basic images, pixels of the color signal basic image generated by the basic image generation unit in a prescribed sequence to generate a basic stream. A link signal generation unit synthesizes a prescribed number of basic streams in the same or different color signal components generated by the basic stream generation unit, encodes bit-length units of the synthesized basic streams to a different bit length, and generates a link signal having a prescribed speed.

Light in primary colors RGB modulated in a first modulation optical system is transmitted through a relay lens () and further divided into a P-polarized light and an S-polarized light by a PS separation wire grid (). The S-polarized light is transmitted through a wavelength spectral filter () to select red/green/blue light components R, G, Bof 615, 515, 450 nm in wavelength, which are then modulated by a Ydevice (). The P-polarized light is transmitted through a wavelength spectral filter () to select red/green/blue light components R, G, Bof 650, 550, 475 nm in wavelength, which are then modulated by a Ydevice (). The 3 -primary color lights modulated by the Y/Ydevices (), () are combined with each other at a PS composite wire grid () to project a synthetic light on a screen.
