Abstract: a back-end system (BES) capable of generating informational programs, characterized by content and schedule, feedable into a digital video broadcasting (DVB) system connectable thereto, wherein the BES is configured to receive input signals from external sources and, in response, to alter the content and/or the schedule that characterize the program or a component thereof prior to feeding said program to the DVB system, with no need to store the altered program in the BES. The BES generally stores a plurality of slides, comprising images, and corresponding schedules and the generated informational programs generally comprise a sequence of slides selected among the stored slides, in accordance with a respective schedule selected among the stored schedules, wherein altering the program in response to the input signal comprises altering said sequence and/or generating in a slide an image, or an image component distinctive from the corresponding image, or image component, stored in the BES.

Abstract: Apparatus for the orthogonal (X,Y) movement which allows high-resolution color photography in both the X and Y directions, by micro-movement of the CCD sensor within a digital camera body is provided which can be used together with a rotatable mount for rotating the CCD sensor from portrait mode to landscape mode, without needing to rotate the camera base.

Abstract: In one embodiment, a scanner is provided having inter alia an optical zoom system, which includes a movable lens assembly and a rotatable mirror. The image to be scanned, the optical zoom system and the scanning head are located along an optical axis. The optical resolution of the image is variable by selectively displacing the lens assembly along the optical axis while simultaneously rotating the rotatable mirror about its center. In a further embodiment, a scanner is provided having inter alia a variable aperture for controlling the infiltration of stray light in a scanner having a plurality of optical resolutions.
