  • Patent number: 11889531
    Abstract: The invention relates to a method for sending control data in a hybrid wireless/broadcast network system, said network system comprising a broadcast network dedicated to transmission of broadcast services through at least a broadcast cell and a wireless network dedicated to transmission of at least a service through a plurality of cells, a cover area of the broadcast cell covering, at least partially, a cover area of a first cell and a cover area of a second cell among the plurality of cells, said method comprising: when control data related to a service of the first cell is identical to control data related to a service of a second cell, sending the control data through the broadcast cell.

  • Patent number: 11444725
    Abstract: The invention relates to a method for transmitting redundancy data in an hybrid broadband/broadcast network system comprising a broadcast network dedicated to transmission of broadcast services and a broadband network dedicated to transmission of at least unicast services, the method being carried out in at least one network entity and comprising the following steps: —selecting (42) a transmission mode for transmitting redundancy data among a plurality of transmission modes supported by the broadband network; —obtaining (43) redundancy data, said redundancy data comprising information for decoding broadcast services broadcasted by the broadcast network; —transmitting (44), via at least one node of the broadband network, the obtained redundancy data according to the selected transmission mode.

  • Publication number: 20160080778
    Abstract: Systems and methods are provided for generating a hybrid signal. A first signal source is configured to provide a first digital signal having a first sample rate, and a second signal source is configured to provide a second digital signal having a second sample rate. A resampling component is configured to resample the second digital signal into a resampled signal having the first sample rate. A multiplexing component is configured to combine the first digital signal and the resampled signal into a multiplexed signal. A digital-to-analog converter is configured to convert the multiplexed signal into an analog signal.

  • Publication number: 20160057463
    Abstract: Systems and methods are provided for generating a hybrid signal. Digital video is broadcast in a first set of at least one time slot of a plurality of time slots comprising the hybrid signal. Mobile data, formatted for reception at a mobile device, is broadcast in a second set of at least one time slot of the plurality of time slots comprising the hybrid signal. Structured data is broadcast in a transition band between the first set of at least one time slot and the second set of at least one time slot.
