Abstract

LA INVENCION SE REFIERE A UN VTR DIGITAL QUE REALIZA LA GRABACION MAGNETICA Y REPRODUCCION, MEDIANTE CODIFICACION DE REDUCCION DE LA TASA DE BITS, DE UNA SEÑAL DE VIDEO DIGITAL, FORMANDOSE UN BLOQUE DE LONGITUD FIJA CONTROLANDO LA CANTIDAD DE CODIGOS DE UN BLOQUE GRANDE INCLUYENDO UNA PLURALIDAD DE PEQUEÑOS BLOQUES SITUADOS DISTANTES ENTRE SI EN UNA PANTALLA EN EL MOMENTO DE LA GRABACION. EL BLOQUE DE LONGITUD FIJA ESTA DIVIDIDO EN VARIOS BLOQUES DE GRABACION, DE MODO QUE LOS COMPONENTES PRINCIPALES DE LOS BLOQUES PEQUEÑOS RESPECTIVOS SE INCLUYAN POR SEPARADO EN LOS BLOQUES DE GRABACION, CON LO QUE SE APLICA LA CORRECCION DE ERRORES PARA FORMAR UNA PLURALIDAD DE BLOQUES DE CORRECCION DE ERRORES. ESTOS BLOQUES SE REDISPONEN DE MODO QUE LOS BLOQUES DE GRABACION, QUE INCLUYEN LOS COMPONENTES PRINCIPALES DE BLOQUES PEQUEÑOS ADYACENTES EN UNA PANTALLA, SEAN TAMBIEN ADYACENTES EN UN MEDIO DE GRABACION. DE ESTE MODO, LA POSIBILIDAD DE DESVIACION EN LA CANTIDAD DE INFORMACION DE CADA BLOQUE GRANDESE SUPRIME PARA MEJORAR EL RENDIMIENTO DE LA CODIFICACION DE LA REDUCCION DE TASA DE BITS Y PARA OBTENER UNA IMAGEN REPRODUCIDA DE ALTA VELOCIDAD Y ALTA CALIDAD. 1.
