  • Configuring method and corresponding communication network device, system, computer readable program product and computer readable storage medium
    Patent number: 10523509
    Abstract: The disclosure relates to a method for configuring an WLAN (Wireless Local Area Network) access point adapted to use at least one operational frequency channel to transmit or receive data when the access point is in an operational mode. The configuring includes checking an availability of at least one restricted frequency channel, a use of the restricted frequency channel being restricted by the availability, choosing the operational frequency channel from a set of frequency channels according to the checked availability, a first configuring comprising a first checking of restricted frequency channels belonging to a first proper sub-set of the set being performed before entering into the operational mode. At least one second checking of at least one restricted frequency channel of the set, that has not been checked as available, is performed after the first configuring.

  • Reception system for multiple-tuner television enabling to automatically connect each tuner to at least an antenna, whatever the number of antennae it comprises
    Patent number: 7750980
    Abstract: A system comprising a first converter linked to a first tuner and optionally, to a second tuner via switching means, optionally a second converter linked to the second tuner means for detecting whether the second converter is in service and means suitable for actuating the switching means in such a way as to link the second tuner to the second converter when one detects that the latter is in service and, in the converse case, to link it to the first converter.

  • Reception system for multiple-tuner television enabling to automatically connect each tuner to at least an antenna, whatever the number of antennae it comprises
    Publication number: 20040093617
    Abstract: System comprising a first converter 1 linked to a first tuner 2 and optionally, to a second tuner 2′ via switching means 6, optionally a second converter 1′ linked to the second tuner 2′ means 11 for detecting whether the second converter 1′ is in service and means suitable for actuating the switching means 6 in such a way as to link the second tuner 2′ to the second converter 1′ when one detects that the latter is in service and, in the converse case, to link it to the first converter 1.
