Abstract:
1. A method of activating loudspeakers in a loudspeaker system including a transmitting unit and a plurality of loudspeakers, each said loudspeaker having an individual receiving unit and an individual address associated therewith, the method comprising: converting output information to be transmitted into packets, the packets including digital data having been compressed, serialized, and modulated for subsequent transmission; addressing plural different audio signals to plural different loudspeakers; transmitting, over AC power lines, the packetized information including packetized data corresponding to the plural different audio signals to the plural different loudspeakers; receiving the packetized information via the receiving units provided to the loudspeakers; comparing the addresses associated with the packetized information with the address associated with the receiving units receiving the information; and when one of the addresses associated with the packetized information corresponds to the address associated with the receiving unit receiving the information, processing the packetized information in order to (a) demodulate, parallelize, and decompress the digital data, (b) convert the digital data from the packetized information into analog data, and (c) feed the analog data to the at least one loudspeaker for output.
