A mobile interactive satellite service includes a first satellite, a base station, and a ground station configured to provide respective and distinct first and second multicast content components to the first satellite and the base station. The first satellite communicates the first multicast content component in a first signal to a mobile device. The base station communicates the second multicast content component in a second signal to the mobile device, which can combine the received signals. For another embodiment, a mobile interactive service includes a mobile device, a first base station, a second base station, and a ground station configured to provide a first multicast content component to the first base station and a second multicast content component to the second base station. The first and second multicast content components are distinct, transmitted in respective first and second multicast signals and are combined by the mobile device.
