Abstract

UNA VIDEO-GRABADORA DIGITAL (3) QUE FUNCIONA PARA RECIBIR UN AVANCE DE LA SEÑAL DE TELEVISION (ATV) QUE DEBE GRABARSE, PROPORCIONA UNA APORTACION TAL COMO UN COEFICIENTE DE BANDA BAJA DE UN CUADRO INTRACODIFICADO DE LA SEÑAL ATV COMO DATOS DE VELOCIDAD VARIABLE, Y GRABA LOS DATOS VIDEO DIGITALES Y DE VELOCIDAD VARIABLE EN UN AREA PRINCIPAL (A1) Y UN AREA MARGINAL (A2) RESPECTIVAMENTE, DE SUCESIVAS VIAS SOBRE UN MEDIO DE GRABACION EN EL CUAL SE LOCALIZA EL AREA MARGINAL SOBRE CADA VIA EN UNA POSICION QUE ES REPRODUCIBLE EN UN MODO DE REPRODUCCION A ALTA VELOCIDAD. LA VIDEO GRABADORA DIGITAL REPRODUCE LOS DATOS GRABADOS EN EL MODO DE REPRODUCCION DE ALTA VELOCIDAD REPRODUCIENDO LA APORTACION DE LA SEÑAL ALMACENADA DEL AREA MARGINAL DE CADA VIA QUE SE LOCALIZA EN AREAS REPRODUCIBLES ESPECIFICAS.
