Method and conference system capable of expanding functions of the conference system by using additional circuit board

A conference system capable of expanding functions comprising:

• a first circuit board comprising:
• a first processor;
• a second circuit board coupled to the first circuit board, the second circuit board comprising:
• a second communication module;
• and
• a second processor coupled to the second communication module;
• a third circuit board coupled to the first circuit board and the second circuit board;
• and
• a first transmitter coupled to the second circuit board;
• wherein the first circuit board and the second circuit board are disposed in a receiver, the second circuit board receives a first wireless packet transmitted from the first transmitter merely through a second communication module, the second processor of the second circuit board controls the second communication module for performing an unpacking process of the first wireless packet to generate first compressed media data, the second processor of the second circuit board generates a first command signal for controlling the first processor of the first circuit board to receive the first compressed media data relayed by the third circuit board from the second circuit board through a data channel, the third circuit board is used for expanding output ports, the first processor decompresses the first compressed media data for acquiring first media contents of the first transmitter, the first media contents are transmitted from the first processor of the first circuit board to the second processor of the second circuit board through the third circuit board, the first media contents are processed by the second processor of the second circuit board for generating processed media contents, the processed media contents are transmitted from the second processor of the second circuit board to the first processor of the first circuit board through the third circuit board, and the first circuit board and the second circuit board are two separate circuit boards before being coupled.
