摘要： A player and an AV amplifier are connected via a cable. An amplifying device amplifies an output signal supplied to an output terminal 14, and outputs the amplified output signal as a transmission signal to the cable. An amplifying device amplifies an output signal supplied to an output terminal, and outputs the amplified output signal as a transmission signal to a cable. An operation device subtracts the output signal supplied to the output terminal from the transmission signal output to the cable. An operation device subtracts the output signal supplied to the output terminal from the transmission signal output to the cable. Therefore, the transmission signal from the AV amplifier is supplied to an input terminal, and the transmission signal from the player is supplied to an input terminal. The transmission signal includes a two-way communication bit indicating whether two-way communication is enabled.

摘要： A video signal and an audio signal are TMDS transmitted from a source device to a sink device. Through a reserved line and a HPD line provided separately from a TMDS transmission line, an Ethernet™ signal is bidirectionally transmitted, and also, a SPDIF signal is transmitted from the sink device to the source device. The Ethernet™ signal bidirectionally transmitted between Ethernet™ transmitter/receiver circuits is differentially transmitted by an amplifier and is received by the amplifier. The SPDIF signal from a SPDIF transmitter circuit is common-mode transmitted from an adder and is received by the adder to be supplied to the SPDIF receiver circuit.

摘要： In an HDMI-connected AV system, bidirectional data transmission between two devices is implemented at low cost. An audio amplifying device serving as an HDMI source and a display device as an HDMI sink are connected additionally using an auxiliary transmission path such as IEEE 1394, so that the data received by the display device 3 from another device is transmitted to the audio amplifying device 2 over the auxiliary transmission path. In this setup, the display device 3 generates a CTS based on a clock regenerated by ACR and on a TMDS clock received from the audio amplifying device 2 via the HDMI, and transmits the CTS over the auxiliary transmission path along with a frequency dividing ratio N. The audio amplifying device generates an audio signal clock from the CTS and N thus received.
