<p>The invention relates to the reception of data by a data broadcast receiver, particularly a mobile data receiver for the Japanese TV data multibroadcast sound subcarrier system. The receiver is controlled to receive a desired type of data, for example, weather forecasts, news, stock prices, etc. The invention provides the transmission of time information which specifies for each type of data when said data will be transmitted or retransmitted. This allows the receiver to enter a standby mode in which the power consumption is reduced. On or slightly before the specified time, the receiver switches on to receive, decode and display the desired data. The invention is also applicable in television receivers having the facility to receive electronic program guides (EPG) or other services. The receiver is informed about the time at which an updated version of the EPG can be expected. In order to reduce power consumption in the receiver's standby mode, the hardware for receiving the EPG is not activated until said specified instant of time.</p> |
