COMPLEX OF FOUR-COLOR DIGITAL TELEVISION FULL COLOURS Russian patent published in 2020 - IPC H04N11/00 

FIELD: physics.

SUBSTANCE: invention relates to colour television systems. Result is achieved by the fact that on the transmitting side the system for transmitting a full colour television signal comprises on the transmitting side a colour digital video camera with sensors of purple, blue, yellow and red light of a light-receiving device, for example a multi-signal CCD array, and on receiving side colour digital television, with four-color light-emitting pixel, consisting of micro emitters of red, yellow, blue and violet light, information between a digital video camera and a digital television is broadcast using a DTS by converting a colour video camera and brightness in combination of three interconnected signals, which consists of red-blue colour difference signal RΔC, yellow-violet colour difference signal YΔV and lightness coefficient signal KΔS, which through a multiplexer of the video camera are successively included in the composition of the DTS. DTS on receiving side is received by television, in which the DTS demultiplex from the DTS signal restores said colour difference signals RΔC, YΔV and lightness coefficient KΔS, from which saturation signals are calculated, where Nr is the red saturation, Ny is the yellow saturation, Nc is the blue saturation, Nv is the violet saturation, wherein N = Nr + Ny + Nc + Nv, and brightness signals, which determine the luminescence brightness of each of the four television signal emitters of the television display pixel, which are calculated by formulas for red micro-emitter (Nr + (1-N)/4) * KΔS, for the yellow micro-emitter Ny + (1-N)/4) * KΔS , for the blue micro-emitter Nc + (1-N)/4) * KΔS, for the violet micro-emitter Nv + (1-N)/4) * KΔS, wherein pixel colour is reflected in orthogonal coordinate system as follows: positive direction of light axis R coincides with positive direction of axis X of three-dimensional Cartesian coordinate system (hereinafter CCS); positive direction of light axis Y coincides with positive direction of Y-axis CCS; positive direction of light axis C coincides with negative direction of X-axis CCS; positive direction of light axis V coincides with negative direction of Y axis of CCS; positive direction of the axis of light Gr coincides with the positive direction of the Z axis of the CCS. Pixel of television display consists of micro emitters of red, yellow, blue and violet light.

EFFECT: providing a system for transmitting a full colour television signal.
