Abstract: A video and audio streaming transmission system is provided. The video and audio streaming transmission system includes a receiving end module, a first transmitting end module and a second transmitting end module. The first transmitting end module obtains a first audio signal, and sends the first audio signal to the receiving end module. The second transmitting end module obtains a second audio signal, and sends the second audio signal to the receiving end module. The receiving end module returns a processed audio signal to the first computer device according to the first audio signal and the second audio signal, so that the first computer device provides the processed audio signal to a conference module.

Abstract: A transmitter device applied to a conference system is disclosed. The conference system further includes a receiver device. The receiver device wirelessly receives an image signal transmitted by the transmitter device, and a display coupled to the receiver device displays the image signal. The transmitter device includes a memory storing an identity information corresponding to an authority of the transmitter device. When the transmitter device is coupled to an information processing device, the transmitter device transmits the identity information to the information processing device. An application driver of the information processing device determines the authority of the transmitter device according to the identity information.
