<p>Device for color decoding a NTSC video signal of a computer capable of representing three different visualisations in one signal R.G.B. (red, green, blue). The invention is characterized by a differentiated decoding of said three visualisation modes and a deep logic analysis of the video signal. Particularly, one of the decodings utilizes a sampling of informations at a frequency equal to the fourteenth of the base frequency of the video signal alternatively on two distinct series of four bits. Another decoding is characterized by a variable position and frequency sampling according to the configuration of the video signal, said sampling frequency being able to go up to half the base frequency of the video signal.</p> |
