Abstract
Un ecualizador de canal adaptable (50) para procesar una senal VSB desmodulada (18) que contienen informacion de television de alta definicion de transmision terrestre opera de manera adaptable en modos ciego, de entrenamiento y dirigido por decisiones. La senal de VSB esta caracterizada por un formato de estructura de datos constituido por una sucesion de campos de datos conteniendo cada uno un segmento de datos precedido por un segmento de sincronizacion de campo. La ecualizacion es expedida al reciclar (35) datos de entrenamiento recibidos a traves del ecualizador mas de una vez durante un campo de datos VSB despues que se detecta un segmento de sincronizacion de campo.
