Abstract

SE OFRECE UNA DESCRIPCION PARA GRABAR Y REPRODUCIR UNA SEÑAL DE VIDEO (ED) DE DEFINICION EXTENDIDA EN / DESDE UNA PISTA SOBRE UN PORTADOR MAGNETICO DE GRABACION. UNA SEÑAL DE VIDEO (ED), TAL COMO UNA SEÑAL DE VIDEO PAL IMERAS LINEAS QUE TIENEN UNA PRIMERA SEÑAL DE LUMINANCIA (Y1) Y UNA SEÑAL DE CROMINANCIA (C), Y UNAS SEGUNDAS LINEAS QUE NO COMPRENDEN SEÑAL DE CROMINANCIA PERO SI UNA SEGUNDA SEÑAL DE LUMINANCIA (Y2) EN LA FORMA DE UNA SEÑAL DE LUMINANCIA MODULADA CON PORTADOR SUPRIMIDO. EL DISPOSITIVO DE GRABACION EN ESTE SISTEMA COMPRENDE UNA PRIMERA LINEA DE SEÑAL (11, 31, 32, 16) PARA PROCESAR LA PRIMERA SEÑAL DE LUMINANCIA, UNA SEGUNDA LINEA DE SEÑAL (11, 18) PARA PROCESAR LA SEÑAL DE CROMINANCIA Y UNA TERCERA LINEA DE SEÑAL (10, 30, 32, 16) PARA PROCESAR LA SEGUNDA SEÑAL DE LUMINANCIA ANTES QUE LAS TRES SEÑALES SE COMBINEN (22) Y SE GRABEN SOBRE EL SOPORTE DE GRABACION. EL DISPOSITIVO DE REPRODUCCION DEL SISTEMA INCLUYE TAMBIEN UNA PRIMERA (48, 50), UNA SEGUNDA (52, 53) Y UNA TERCERA LINEA DE SEÑAL (48, 73, 83) PARA PROCESAR LA PRIMERA SEÑAL DE LUMINANCIA, LA SEÑAL DE CROMINANCIA Y LA SEGUNDA SEÑAL DE LUMINANCIA RESPECTIVAMENTE. TAMBIEN SE DESCRIBEN VARIOS DISPOSITIVOS GRABADORES Y DISPOSITIVOS DE REPRODUCCION ASOCIADOS. ADEMAS SE DESCRIBEN MEDIOS CONVERSORES CON LOS QUE UNA SEÑAL DE VIDEO ED PUEDE CONVERTIRSE EN UNA SEÑAL QUE PUEDE SER GRABADA POR UNA GRABADORA DE VIDEO Y CON LOS QUE UNA SEÑAL LEIDA POR UNA GRABADORA DE VIDEO PUEDE CONVERTIRSE EN UNA SEÑAL DE VIDEO ED.
