Wireless digital transmission system for loudspeakers
First Claim
1. A loudspeaker system, comprising:
- a transmitting unit;
a plurality of loudspeakers, each said loudspeaker having an individual receiving unit and an individual address associated therewith;
wherein the transmitting unit is configured to;
convert output information to be transmitted into packets, the packets including digital data having been compressed, serialized, and modulated for subsequent transmission,address plural different audio signals to plural different loudspeakers, andtransmit, over AC power lines, the packetized information including packetized data corresponding to the plural different audio signals to the plural different loudspeakers; and
wherein the loudspeakers are each configured to;
receive the packetized information via their respective receiving units;
compare the addresses associated with the packetized information with the address associated with their respective receiving units receiving the information; and
when one of the addresses associated with the packetized information corresponds to the address associated with the respective receiving unit receiving the information, process 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) cause the analog data to be output by the respective loudspeaker.

Abstract
This invention relates to a wireless digital transmission system for loudspeakers comprising: compression means for the file representing the digital audio signal of the “compact disc” type, a transmission device comprising means of converting this compressed signal into a series signal moving by packets going to a modulator circuit with phase quadrature and means of transmitting the signals exiting the modulator circuit with phase quadrature to the domestic network for feeding electricity; a receiving device comprising means of connecting to this domestic network and of extracting from the feed electrical signal, by a demodulator with phase quadrature, data packets moving the digital audio signal to convert it into a parallelized digital signal sent to a decompression circuit; means of converting the decompressed digital signals into an analog signal intended to feed a loudspeaker after adequate amplification.
