Abstract

SISTEMA DE CODIFICACION DE CINTAS DE VIDEO. EL SISTEMA DE CODIFICACION DE CINTAS DE VIDEO OBJETO DE LA INVENCION, TIENE LA FINALIDAD MEDIANTE LA INTRODUCCION DE UNA SEÑAL DIGITAL CODIFICADA DURANTE LA GRABACION DE UNA CINTA DE VIDEO, DETECTAR EL ORIGEN DE LAS CINTAS DE VIDEO GRABADAS QUE SE ENCUENTRAN DISTRIBUIDAS EN EL MERCADO Y CON ELLO LUCHAR CONTRA EL FRAUDE PRODUCIDO MEDIANTE LA DISTRIBUCION DE COPIAS ILEGALES. EL SISTEMA ESTA CONSTITUIDO POR LA ASOCIACION FUNCIONAL DE UN CODIFICADOR (1) ASOCIADO A CADA UNO DE LOS VIDEOS (2) QUE COMPONEN UNA DUPLICADORA DE CINTAS DE VIDEO Y UN DECODIFICADOR (4) UNIDO A UN VIDEO REPRODUCTOR (5) ESPECIALMENTE PREPARADO, CON LA COLABORACION DE UN MONITOR (6) PARA LA PRESENTACION DE LA INFORMACION CODIFICADA. LA PARTE DEL SISTEMA CORRESPONDIENTE A LA DECODIFICACION SE PUEDE PRESENTAR EN FORMA ESTACIONARIA O PORTATIL. EN ESTE SEGUNDO CASO, SE HA PREVISTO LA EXISTENCIA DE UN SISTEMA DE BATERIAS RECARGABLES PARA SU UTILIZACION DE FORMA AUTONOMA.VIDEO TAPE CODING SYSTEM. THE SYSTEM OF CODING OF VIDEO TAPES OBJECT OF THE INVENTION, HAS THE PURPOSE THROUGH THE INTRODUCTION OF A DIGITAL SIGNAL CODED DURING THE RECORDING OF A VIDEO TAPE, TO DETECT THE ORIGIN OF THE RECORDED VIDEO TAPES THAT ARE FOUND IN THE DISTRIBUTED THEREFORE FIGHT AGAINST THE FRAUD PRODUCED THROUGH THE DISTRIBUTION OF ILLEGAL COPIES. THE SYSTEM IS CONSTITUTED BY THE FUNCTIONAL ASSOCIATION OF A CODER (1) ASSOCIATED WITH EACH OF THE VIDEOS (2) COMPOSING A VIDEO TAPE DUPLICATOR AND A DECODER (4) JOINED BY A SPECIALLY PREPARED VIDEO (5), WITH THE COLLABORATION OF A MONITOR (6) FOR THE PRESENTATION OF THE CODED INFORMATION. THE PART OF THE SYSTEM CORRESPONDING TO DECODING MAY BE PRESENTED ON A STATIONARY OR PORTABLE BASIS. IN THIS SECOND CASE, THE EXISTENCE OF A RECHARGEABLE BATTERY SYSTEM FOR ITS AUTONOMOUS USE IS PROVIDED.
