Title:
DIGITAL VIDEO BROADCAST-TERRESTRIAL (DVB-T) RECEIVER INTEROPERABLE WITH A GSM TRANSMITTER IN A NON-INTERFERING MANNER
Document Type and Number:
WIPO Patent Application WO2003105386
Kind Code:
A3
Abstract:
A method and a device used for displaying wideband information to a user has a return channel made through a cellular mobile terminal (CMT) 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 receiving information in a bit-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 bit 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. In one embodiment the first band of radio frequencies is a DVB-T 470-862MHz reception band, and the second band of radio frequencies is a GSM 880-915MHz transmission band. In another embodiment the first band of radio frequencies is a DTV 794-806MHz reception band, and the second band of radio frequencies is a CMT 824-849MHz transmission band.
