IMPROVEMENTS TO TELEVISION AND RADIO PROGRAMME CONTROL

摘要

A system and method for controlling channel changes in television or digital radio having a tuner or receiver ( 12 ). The system comprises an enhanced zap mechanism ( 34 ) that is operable to monitor channel change commands received from a user over a zapping session, identify discarded channels and prevent the tuner or receiver ( 12 ) from returning to the discarded channels during the rest of the zapping session, unless it is determined that a programme transmitted on the discarded channel has changed.
