User Oriented Broadcasting System Processing of Audio Signal Using SOLA Converter Based on FPGA

摘要

The present invention relates to a user oriented broadcasting system processing audio signal using a SOLA converter based on FPGA. The present invention includes a mixer control unit which outputs a mixed analog audio signal, an interface unit which is electrically connected to the mixer control unit and controls the mixer control unit, a main computer which is electrically connected to the interface unit and controls the interface unit, a remote amplifier which is connected to the mixer control unit through Ethernet and transmits a voice data signal and a control signal to the mixer control unit, a relay control unit which determines a speaker to which the audio signal outputted from the mixer control unit by the control signal of the interface unit is transmitted, and a plurality of local computers which are electrically connected to the interface unit and controls the interface unit. According to the present invention, a bidirectional broadcast is performed.
