Abstract: A system and a method for encoding and decoding stereoscopic images are described. A stereoscopic image comprises at least two sub-images arranged according to a first configuration and intended for a user's right eye and left eye, respectively. During the video signal post-production stage, a chromatic code is embedded which in adapted to provide information about said configuration. At receiver level, decoding means (14) are used which are adapted to receive said stereoscopic image, recognise the configuration of said at least two sub-images based on information embedded into said stereoscopic image, and arrange said at least two sub-images according to a second predetermined configuration.

Abstract: A method for producing a finely subdivided insulating material includes the steps of: preparing a fluid composition by mixing together an alkaline silicate, a metal hydroxide and an impermeabilizing agent, heat-treating the composition so as to produce a plurality of small cavities in the composition, and finely subdividing the composition.

Abstract: An apparatus comprises a container, suitable for containing a plant and a respective culture substrate, and a lighting arrangement associated with said container.

Abstract: A method of producing foamed clay with optimum characteristics of porosity, mechanical resistance, high coefficients of reduced weight, and thermal and acoustic insulation, wherein a fluid mass consisting of clay is formed, into which compostions reacting therebetween are put so as to cause the homogenous foaming of the whole clay mass.
