Abstract

SE DESCRIBEN TÉCNICAS RELACIONADAS CON LA DERIVACIÓN DEL VECTOR DE MOVIMIENTO DEL LADO DEL DECODIFICADOR. POR EJEMPLO, ESTA DESCRIPCIÓN DESCRIBE TÉCNICAS RELACIONADAS CON LA APLICACIÓN DE UNA O MÁS RESTRICCIONES A LA INFORMACIÓN DE MOVIMIENTO, COMO UN VECTOR DE MOVIMIENTO (MV) DERIVADO POR DMVD, Y/O UNA DIFERENCIA DE MV ENTRE UN MV INICIAL Y UN MV DERIVADO POR DMVD. CUANDO LA RESTRICCIÓN SE APLICA AL DMVD, EN CIERTOS EJEMPLOS, SOLO LA INFORMACIÓN DE MOVIMIENTO DERIVADA QUE CUMPLE CON LA RESTRICCIÓN SE CONSIDERA INFORMACIÓN DE MOVIMIENTO VÁLIDA. LAS CONDICIONES PUEDEN COLOCARSE EN LAS RESTRICCIONES.
