1. A communication system comprising a transmitter device and receiver devices, wherein:
the transmitter device is configured to transmit data and identification information to the receiver devices, the identification information comprising first information indicative of a communication mode and second information indicative of a receiver device of a transmission destination data;
each of the receiver devices is configured to determine whether the receiver device receives the data based on at least a part of the second information when the communication mode of the first information is indicative of a data transmission mode from the transmitter device;
the communication mode of the first information is indicative of a data transmission mode using single cast or a data transmission mode using broadcast;
when the communication mode of the first information is indicative of the data transmission mode using single cast, each of the receiver devices is configured to determine whether the receiver device receives the data based on all bits of the second information;
the second information comprises bits of information;
the transmitter device is configured to set bits of third information to the receiver devices, respectively;
when the communication mode of the first information is indicative of the data transmission mode using single cast, and when all bits of the second information match all bits of the third information, each of the receiver devices receives the data; and
when the communication mode of the first information is indicative of the data transmission mode using broadcast, and when several bits of the second information match several bits of the third information, each of the receiver devices receives the data.
