The present invention provides an audio/visual data communication system including an audio/visual data reproducing device capable of changing the type of data to be transmitted. Further, the present invention provides an audio/visual data transmitting device and an audio/visual data reproducing device forming the audio/visual data communication system. An audio data reproducing speaker 3 includes an instruction input unit 33 that inputs an instruction to change data transmitted from an audio data transmitting device, a message generating unit 32 that generates a message for requesting to change data on the basis of the instruction, and a message transmitting unit 31 that transmits the message. The audio data transmitting device includes a message receiving unit that receives the message transmitted from the message transmitting unit 31 , a data setting unit that sets data on the basis of the message, a data generating unit that generates transmission data on the basis of the data set by the data setting unit, and a data transmitting unit that transmits the transmission data.
