AUTOMATED SYSTEM FOR DISPLAYING VIDEO "METROFILM", STANDALONE ELEMENT FOR DISPLAYING ONE VIDEO SEQUENCE FRAME AND METHOD FOR DISPLAYING VIDEO FOR MOVING VIEWERS Russian patent published in 2009 - IPC G09F19/22 G09F9/33 

FIELD: physics; video technology.

SUBSTANCE: standalone element for displaying one video sequence frame is made in form of a module, which forms a matrix image, containing a speed sensor, consisting of two photodiodes, lying horizontally at a distance from each other, at least one vertical line of tri-coloured light-emitting diodes with a control unit in form of a controller with a micro code, which provides for self-diagnosis, reception, storage and transmission of data to the next module or control computer, determination of the speed of the vehicle window at the beginning of passage from light-emitting diode signals and subsequent automation of synchronisation of the beginning of display and duration of display of the frame relative a viewer. The automated system for displaying video includes a row of data carriers, placed along the path of the vehicle, a control processor, connected to an external control system and a set of ordered modules for formation of an animated matrix image based on the after-image effect. Each module is a direct and reverse command and/or data relay for the next module.

EFFECT: increased definition of the animated image regardless of the change in speed and type of the train, shape and number of windows on the wagon.
