Abstract: A method and apparatus for transmitting a media program comprising audiovisual data. The method comprises the steps of transmitting the audiovisual data from a ground center to a satellite; transponding the audiovisual data to a ground-based hub; and transmitting the audiovisual data from the ground-based hub to a display entity if the satellite is obscured from the display entity. The apparatus comprises a ground transmitter transmitting the audiovisual data from a ground center to a satellite; satellite for transponding the audiovisual data; and a ground-based hub, having a receiver for receiving the transponded audiovisual data and a hub transmitter for transmitting the audiovisual data from the ground-based hub to a display entity if the satellite is obscured from the display entity.
