Claim 0:
1. A method for expanding functions of a conference system, the conference system comprising a first transmitter and a receiver coupled to the first transmitter, the method comprising:
providing a first circuit board and a second circuit board disposed in the receiver;
receiving a first wireless packet transmitted from the first transmitter merely through a second communication module of the second circuit board;
controlling the second communication module for performing an unpacking process of the first wireless packet by a second processor of the second circuit board to generate first compressed media data;
generating a first command signal by the second processor of the second circuit board for controlling a first processor of the first circuit board to receive the first compressed media data relayed by a third circuit board from the second circuit board through a data channel;
decompressing the first compressed media data by the first processor for acquiring first media contents of the first transmitter;
transmitting the first media contents from the first processor of the first circuit board to the second processor of the second circuit board through the third circuit board;
processing the first media contents by the second processor of the second circuit board for generating processed media contents; and
transmitting the processed media contents from the second processor of the second circuit board to the first processor of the first circuit board through the third circuit board;
wherein the first circuit board and the second circuit board are two separate circuit boards before being coupled, the third circuit board is used for expanding output ports, and the third circuit board is coupled to the first circuit board and the second circuit board.
