Abstract

SE PROPORCIONA UN METODO DE COMPRESION PARA LA TRANSMISION DE SEÑALES DE VIDEO DIGITALES ENTRE UNA MEMORIA INTERMEDIA CODIFICADORA Y UNA MEMORIA INTERMEDIA DESCODIFICADORA. SE PROPORCIONA UN RETRASO QUE SE PUEDE AFINAR EN EL CODIFICADOR, ADECUADAMENTE EN LA FORMA DE UNA PARTE DE LA MEMORIA INTERMEDIA CODIFICADORA, CON DATOS QUE SON LEIDOS FUERA PARA UN CANAL DE COMUNICACIONES A UNA VELOCIDAD DETERMINADA POR LA VELOCIDAD DE BITS DE ENTRADA DE LAS SEÑALES RECIBIDAS EN UN NUMERO PREDETERMINADO DE PERIODOS DE TRAMAS POSTERIORES. EL USO DEL RETRASO AJUSTABLE MEJORA LA EFICIENCIA DE LA MEMORIA INTERMEDIA DESCODIFICADORA MANTENIMIENTO UN NIVEL RELATIVAMENTE CONSTANTE DE LA AMPLITUD IRRELEVANTE DE LA MEMORIA INTERMEDIA DESCODIFICADORA DE LAS VELOCIDADES DE BITS DE SEÑAL.
