摘要：
A communication system includes a reception device and at least one transmission device. The transmission device includes: a signal transmission unit which transmits at least one unicast signals and a multicast signal to the reception device. The reception device includes: a plurality of signal reception units which receive at least one the unicast signals and the multicast signal from the transmission device; a first control unit which receives the unicast signals from the transmission device using all of the plurality of signal reception units when only the unicast signals are received; and a second control unit which receives the unicast signals from the transmission device using some of the plurality of signal reception units, and simultaneously receives the multicast signal from the transmission device using another signal reception unit of the plurality of signal reception units, when the unicast signals and the multicast signal are received.
