Abstract

UN APARATO QUE DECODIFICA UN VECTOR DE MOVIMIENTO CODIFICADO, Y QUE COMPRENDE UN NUMERO DE MEMORIAS DE REGISTRO (PMV) IGUAL A LA SUMA DE LOS MAXIMOS NUMEROS DE TRANSMISION N Y M DE LOS VECTORES DE MOVIMIENTO PREDICHOS EN LA DIRECCION FRONTAL Y TRASERA. UN CONTADOR DE VECTOR DE MOVIMIENTO CUENTA EL NUMERO DE TRANSMISION DE LOS VECTORES DE MOVIMIENTO Y ENVIA UNA SEÑAL QUE REPRESENTA EL NUMERO DE VECTORES DE MOVIMIENTO. UN GENERADOR DE SEÑAL QUE DESIGNA UN INDICE DE REGISTRO SEÑALA EL INDICE DE [1 A N ((N + 1)-(N +M))] EN LA ORDEN DE TRANSMISION DE LOS VECTORES DE MOVIMIENTO PREDICHOS EN LA DIRECCION FRONTAL O TRASERA DE ACUERDO CON LA INFORMACION CONSEGUIDA TAL COMO EL MODO DE COMPENSACION DE MOVIMIENTO, EL TIPO DE PREDICCION, ESTRUCTURA DE IMAGEN Y OTROS DEL VECTOR DE MOVIMIENTO, Y LA SEÑAL VENIDA DEL CONTADOR DEL VECTOR DE MOVIMIENTO, Y ENTONCES PROPORCIONA UNA CONEXION PARA CORRELACIONAR LAS MEMORIAS DE REGISTRO (PMV) CON LOS VECTORES DE MOVIMIENTO UNO A UNO. UN CIRCUITO DIFERENCIAL CALCULA LA DIFERENCIA ENTRE EL VECTOR DE MOVIMIENTO INTRODUCIDO EN EL, Y EL VALOR BUSCADO POR LA MEMORIA DE REGISTRO (PMV) CORRELACIONADO DE ACUERDO CON EL MODO DE COMPENSACION DE MOVIMIENTO Y OTROS.
