The invention which is the subject of the application relates to a television system apparatus and method wherein the broadcast data receiver includes at least two tuners. Each tuner is controllable to tune to a frequency of a known RF carrier for data relating to one or a plurality of selectable television channels. In order to avoid or reduce the delay which can appear on screen when the user selects to change channels a method and apparatus is provided whereby, based upon previous user channel selection patterns, the apparatus predicts the channel which is next to be selected and if one of the tuners is free, that tuner is controlled to tune to the RF carrier frequency for the predicted channel such that the data for that channel is available, should the channel subsequently be selected by the user. |
