A method for providing product information to at least one media displaying device having output means and a data reception unit, the at least one media displaying device being located in at least one store, each store comprising at least one data emitting unit, comprising the steps of: (a) generating, at a central back-office server connected to the data emitting unit of the store of the media displaying device, an individual glyph corresponding to each different character or symbol of the product information; (b) generating at least a display script comprising reference and position data of said glyphs in the product information; (c) transmitting the display script and the individual glyphs to the data emitting unit of the store of the media displaying device; (d) transmitting by the data emitting unit of the store of the media displaying device the display script to the media displaying device, receiving the display script by the media displaying device and loading it into a memory of the media displaying device; (e) broadcasting by the data emitting unit of the store of the media displaying device the individual glyphs with their reference data and receiving the individual glyphs with their reference data by the media displaying device; (f) determining by the media displaying device for each received glyph if its reference data corresponds to one of the reference data of the layout script loaded into the memory and selecting and loading into the memory of the media displaying device only those received individual glyphs corresponding to the reference data comprised in the display script loaded into the memory of the media displaying device; and (g) displaying the selected and loaded individual glyphs at the output means of the media displaying device according to the position data comprised in the display script loaded into the memory of the media displaying device. (a) generating, at a central back-office server connected to the data emitting unit of the store of the media displaying device, an individual glyph corresponding to each different character or symbol of the product information; (b) generating at least a display script comprising reference and position data of said glyphs in the product information; (c) transmitting the display script and the individual glyphs to the data emitting unit of the store of the media displaying device; (d) transmitting by the data emitting unit of the store of the media displaying device the display script to the media displaying device, receiving the display script by the media displaying device and loading it into a memory of the media displaying device; (e) broadcasting by the data emitting unit of the store of the media displaying device the individual glyphs with their reference data and receiving the individual glyphs with their reference data by the media displaying device; (f) determining by the media displaying device for each received glyph if its reference data corresponds to one of the reference data of the layout script loaded into the memory and selecting and loading into the memory of the media displaying device only those received individual glyphs corresponding to the reference data comprised in the display script loaded into the memory of the media displaying device; and (g) displaying the selected and loaded individual glyphs at the output means of the media displaying device according to the position data comprised in the display script loaded into the memory of the media displaying device.
