Abstract: A satellite communication system using hierarchical modulation to transmit a plurality of modulated signals to sub-regions within a region. Each modulated signal includes high priority content and low priority content. The system includes a satellite equipped with a plurality of satellite transmitters coupled to a plurality of antenna elements, e.g. a phased array of antenna elements. The antenna elements are utilized selectively to direct a modulated signal from a satellite transmitter to a distinct sub-region. The satellite transmitters and antenna also cooperate to broadcast the high-priority content to the region such that a ground receiver traveling from a first sub-region to an adjacent second sub-region adjacent will not experience a loss of high-priority content. First low-priority content of a first modulated signal directed to the first sub-region is independent of second low-priority content of a second modulated signal directed to the second sub-region.

Abstract: A hybrid broadcast receiver and method of operating a memory in the receiver. The memory is used to store received data being processed in the receiver. The receiver is configured to receive both a terrestrial signal broadcast by a terrestrial transmitter and a satellite signal broadcast by a satellite transmitter. Terrestrial data from the terrestrial signal is stored in a terrestrial portion of the memory that includes a top end or first location of the memory. Satellite data from the satellite signal is stored in a satellite portion of the memory that includes a bottom end or last location of the memory.
