Abstract: A system and method for the transmission of a dynamic bandwidth dynamic content signal across a transmission-tiered communications network is disclosed. The network enables simultaneously the transmission of an extended-bandwidth signal carrying a full set of content information units and a set of unique CATV-standard-bandwidth signals carrying optionally different sub-sets of content information units selected specifically from the extended-bandwidth signal and delivered to targeted groups of subscribers. The unique CATV-standard-bandwidth signals are created by an extended signal-processing unit in response to specific control information generated in the network following particular requests submitted by the network the subscribers. Subsequently, the unique signals are transmitted to the subscribers via CATV-standard components.

Abstract: A method of manufacturing a multi-layer optical information carrier with fluorescence reading/recording is presented. A structure is fabricated, being formed of a substrate carrying a fluorescent film on one or both surfaces thereof, wherein the substrate is transparent with respect to incident radiation used for the fluorescence reading/recording. A patterned structure is applied to the fluorescent film under predetermined process conditions, such as to produce a fluorescent patterned structure with a surface relief in the form of an array of discrete fluorescent regions. The same procedure is repeated a required number of times, so as to obtain at the end of the process a multi-layer optical information carrier.
