The present invention relates to a system, device and method for two-way satellite communication using a dual channel communication configuration to make better use of limited bandwidth. The two channels include a dedicated Unicast channel for each remote VSAT terminal and a dedicated Multicast channel that is a shared resource for all the VSAT terminals in the network. Each VSAT terminal is provided with two separate tuners, one for Unicast information and one for Multicast information. The system thus provides Unicast information through the Unicast channel to the Unicast receiver in the VSAT terminal to individual destination VSAT terminals, and sends Multicast information to all VSAT terminals via the Unicast channel and the Unicast receivers in each VSAT terminal.
