ABSTRACT:
The present invention is directed to provide an AV processing device and the like that allow mixing three or more AV signals through easy operation. According to the invention, an AV processing device30includes an input unit310inputting three or more AV signals that are audio signals or video signals, a coordinate point assigning unit322assigning a given coordinate point in a predetermined two-dimensional region in which a coordinate axis for each input AV signal indicating its mixing rate from minimum to maximum is virtually assigned, a mixing rate calculator331calculating the mixing rate of each AV signal based on the coordinate axis for the AV signal and the assigned coordinate point, a mixed AV signal generator332generating mixed AV signals based on the calculated mixing rate of each AV signal, and an output unit350outputting the generated mixed AV signals.
