Abstract
UN COMPRESOR DE SEÑALES DE VIDEO INCLUYE UN APARATO (11-17) PARA GENERAR VECTORES DE MOVIMIENTO PARA LOS RESPECTIVOS BLOQUES DE DATOS DE VIDEO. UNOS DE LOS VECTORES DE MOVIMIENTO (QUE NO SEAN AQUELLOS QUE PROPORCIONAN (18) LA DIRECCION PARA CO-LOCALIZAR LOS BLOQUE EN OTROS MARCOS) SE DETERMINAN PARA SER CANDIDATOS PARA LA CONVERSION A VECTORES QUE PROPORCIONAN LA DIRECCION PARA CO-LOCALIZAR BLOQUES. SIN EMBARGO, SE EXCLUYE LA CONVERSION (100, 102) SI EL VECTOR SE DETERMINA PARA SER CORRELACIONADO CON UNO DE LOS VECTORES DE MOVIMIENTO VECINOS.
