Abstract

SE PROPONE UN DESCODIFICADOR DE VIDEO QUE RECIBE LOS PAQUETES DE INFORMACION DE VIDEO RELATIVA AL MOVIMIENTO DE LAS IMAGENES DE VIDEO A PARTIR DE UNA RED DE CONMUTACION DE PAQUETES. DE ACUERDO CON LA INVENCION SE ELIMINAN UNA GRAN CANTIDAD DE GASTOS DE HARDWARE Y SE GANA MUCHA MAS FLEXIBILIDAD COMPARADA CON LOS DESCODIFICADORES DE ESTE TIPO CONOCIDOS HASTA AHORA EN LOS PROCESOS DE DESCODIFICACION, IMPLANTADOS A TRAVES DE MEDIOS (DEC1, DCE2) DE DESCODIFICACION, FUNCIONANDO DE FORMA ASINCRONA CON RESPECTO A LOS PROCESOS DE REPRODUCCION, IMPLANTADOS A TRAVES DE MEDIOS (DIS) DE REPRODUCCION. ADEMAS, Y TAMBIEN EN CONTRASTE CON LOS DESCODIFICADORES ANTERIORES DE ESTE TIPO, EL DESCODIFICADOR DE VIDEO DE ACUERDO CON LA PRESENTE INVENCION NO ESTA EXPLICITAMENTE SINCRONIZADO A SUS CODIFICADORES CORRESPONDIENTES MEDIANTE LA COBERTURA EXPLICITA DE LOS ULTIMOS SISTEMAS DE RELOJ. ESTO SE REALIZA A TRAVES DE ACCIONES DE FRENADO DENTRO DE UNA MEMORIA (FSM) DE ALMACENAMIENTO PRINCIPAL COLOCADA ENTRE LOS MEDIOS (DEC1, DEC2) DE DESCODIFICACION Y LOS MEDIOS (DIS) DE REPRODUCCION. LA LONGITUD VARIABLE DE UN SEPARADOR DE ESTE TIPO PUEDE SER UTILIZADA PARA EL CONTROL DE LA VELOCIDAD DE LOS PROCESOS DE REPRODUCCION A FIN DE PREVENIR EL SUBFLUJO O SOBREFLUJO DE LOS ULTIMOS SEPARADORES Y LA DEGRADACION CORRESPONDIENTE DE LA IMAGEN. ESTO ULTIMO ES REALIZADO A TRAVES DE MEDIOS (CON) DE CONTROL.
