The present invention provides a videoconference system, suitable for a plurality of participant units join the conference. The videoconference system comprises a central control unit, a video decoding unit and a video encoding unit. Wherein, the central control unit receives the individual video data streams of a plurality of participant units, and selectively outputs the video data streams of part of all participant units. The video decoding unit receives the individual video data streams that are chosen, disassembles the audio signal and the video signal of the individual video data stream, and then mixes the disassembled audio signals and the disassembled video signals into an audio mixed signal and a video mixed signal respectively. The video encoding unit receives the audio mixed signal and the video mixed signal, encodes the audio mixed signal and the video mixed signal to a video mixed data stream, and then sends the video mixed data stream to the participant units.
