Abstract

DISPOSITIVO DE GRABACION/REPRODUCCION DE CINTA MAGNETICA DEL TIPO DE BARRIDO HELICOIDAL ADAPTADO PARA GRABAR Y/O REPRODUCIR UNA SEÑAL DE VIDEO CODIFICADA DIGITALMENTE, QUE CONSTA DE UN DISPOSITIVO DE CODIFICACION (3). EN EL MODO DE GRABACION, EL DISPOSITIVO DE CODIFICACION (3) REALIZA LA CODIFICACION DE CANAL SOBRE UNA SEÑAL DE GRABACION DIGITAL (C), PARA OBTENER UNA SEÑAL DE CANAL (D) Y GRABARLA EN UNA CINTA MAGNETICA (7.1). EN EL MODO DE REPRODUCCION, EL DISPOSITIVO DE CODIFICACION REALIZA UNA DECODIFICACION DE CANAL SOBRE LA SEÑAL DE CANAL (H) LEIDA EN LA CINTA MAGNETICA (7.1), DE FORMA QUE SE OBTIENE UNA SEÑAL DE REPRODUCCION DIGITAL QUE ES UNA REPLICA DE LA SEÑAL DE GRABACION ORIGINAL (C). CON ESTE OBJETIVO, EL DISPOSITIVO DE CODIFICACION (3) CONSTA DE UN GENERADOR DE SECUENCIAS DE DATOS (3.3), ADAPTADO PARA GENERAR UNA SECUENCIA DE DATOS (E) DEFINIDA POR EL POLINOMIO P(X) = X SUP,15} + X SUP,A} + 1, DONDE A ES 7 U 8. ADEMAS, EL CIRCUITO DE CODIFICACION (3) PUEDE CONSTAR DE UN DISPOSITIVO XOR (3.2) EN EL QUE LA SEÑAL (C, H) A PROCESAR SE COMBINA CON LA SECUENCIA DE DATOS GENERADA (E) Y DE UN ELEMENTO DE SELECCION (3.1) PARA SELECCIONAR LA SEÑAL A PROCESAR (C, H) EN LA SEÑAL DE GRABACION (C) Y EN LA SEÑAL DE CANAL (H), EN FUNCION DEL MODO DE FUNCIONAMIENTO DEL DISPOSITIVO DE GRABACION/REPRODUCCION.
