Abstract

UNA SEÑAL DIGITAL PUEDE GRABARSE Y/O REPRODUCIRSE EN UN MODO DE IMAGEN DE ALTA CALIDAD Y UN MODO A LARGO PLAZO CON DIFERENTES PROPORCIONES DE COMPRESION EN UN MEDIO DE GRABACION SIMPLE EN FORMA DE DISCO. SE SUMINISTRA UNA SALIDA DE UN SINTONIZADOR (11) A UN CIRCUITO DE AISLAMIENTO DE SONIDO/DATOS (12) DONDE SE AISLAN UNA SEÑAL DE VIDEO, UNA SEÑAL DE AUDIO Y LOS DATOS QUE LAS ACOMPAÑAN. LA SEÑAL DE VIDEO SE SUMINISTRA A TRAVES DE UN CIRCUITO DE CONVERSION A/D (14), UN CIRCUITO DE AISLAMIENTO Y/C (15), UN CIRCUITO DE DEMODULACION DE COLOR (16), UN PREFILTRO (18) Y UN CIRCUITO DE MUESTREO REPETIDO (59) A UN CIRCUITO DE COMPRESION (20) DONDE SE COMPRIME LA SEÑAL DE VIDEO. LA SEÑAL DE AUDIO SE SUMINISTRA A TRAVES DE UN CIRCUITO DE CONVERSION A/D (34), UN PREFILTRO (38) Y UN CIRCUITO DE MUESTREO REPETIDO (39) A UN CIRCUITO DE COMPRESION (40) DONDE SE COMPRIME LA SEÑAL DE AUDIO. AQUI, LA PROPORCION DE COMPRESION SE CONMUTA MEDIANTE UNA SEÑAL DE CONTROL QUE ESPECIFICA EL MODO DE IMAGEN DE ALTA CALIDAD/DURACION PROLONGADA. LA SEÑAL DE VIDEO COMPRIMIDA, LA SEÑAL DE AUDIO COMPRIMIDA Y LOS DATOS QUE LAS ACOMPAÑAN SE COMBINAN EN DATOS SERIE MEDIANTE UN CIRCUITO MULTIPLEX (41) Y A TRAVES DE UNA MEMORIA FIFO (42) SE GRABAN EN UN MEDIO DE GRABACION EN FORMA DE DISCO (100). DURANTE LA REPRODUCCION, LA SEÑAL DE VIDEO Y LA SEÑAL DE AUDIO SE EMITEN DE ACUERDO CON EL PROCEDIMIENTO ANTERIORMENTE MENCIONADO EN ORDEN INVERSO.
