Abstract

A method and a device used for displaying wideband information to a user has a return channel made through a cellular mobile terminal providing interactivity. The device includes a receiver for communicating in a first band of radio frequencies and a transmitter for communicating in a second band of radio frequencies. The method includes receiving information in a symbol-wise manner with the receiver in a first band of RF frequencies; generating a notification of an occurrence of a burst transmission from the transmitter; and in response to the notification, terminating the reception of the information for a portion of one symbol time corresponding to a duration of the burst transmission. The method may include an optional step, further in response to the notification, of reducing power consumption by turning off at least a portion of the receiver for a period of time corresponding to the duration of the burst transmission.
