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 (10) has a first antenna (12) and a second antenna (20), a receiver (14, 16) that is coupled to the first antenna and a transmitter (24) that is coupled to the second antenna. The method includes, prior to receiving information in a symbol-wise manner with the receiver in a first band of radio frequencies, generating a notification of reception with the receiver by asserting a DVB_RX_ON signal (16A) and, in response to the notification, requesting a change of transmitter transmission frequencies from a second band of radio frequencies to a third band of radio frequencies that is predetermined to avoid interference with the reception of the information in the first band of radio frequencies.
