Method for scanning frequencies, tuner, dvb-h receiver comprising the tuner, and mobile phone comprising the dvb-h receiver

Tuner (16) for scanning frequencies of a network, in order to determine available frequencies

• the network comprising a plurality of coverage zones,
• a respective signal being emitted over each coverage zone of the network, at a respective frequency,
• the tuner (16) being intended to be located in one of the coverage zones, referred to as the current coverage zone, a signal, referred to as the current signal, being emitted over the current coverage zone,
• the current signal conveying a plurality of services according to a time slicing method, so that each service is conveyed during a periodical time slice dedicated to the service,
• the tuner (16) being configured for synchronizing with the current signal during the time slices dedicated to the at least one service intended to be received,
• the tuner (16) comprising:
• means (20, 22) for obtaining a group of frequency values of the frequencies of coverage zones of the network,
• the tuner (16) being characterized in that it is configured for, during time intervals separating the time slices dedicated to the at least one service intended to be received, scanning all the frequency values of the group in order to determine available frequencies, whatever is the number of frequency values in the group.
