摘要： A satellite-based communications network employing at least one satellite and a plurality of user terminals adapted for use with the communications network. The network includes a transmitter for transmitting data to the plurality of user terminals, where the data includes a plurality of broadcast modes and/or services. The transmitter transmits data in a packetized format in which a predetermined number of data packets are transmitted in a frame, where the frame is defined as a predetermined period of time. Further, the transmitter transmits each of the plurality of broadcast modes utilizing a single carrier frequency. Each of the plurality of user terminals includes a receiver for receiving the transmitted data and for regenerating the data so that the data is made available to a device coupled to the user terminal.
