Abstract:
1. A device, comprising: a processing device configured to: transmit a second signal, being multiplexed to the transmission line, as a common-mode signal to the external device, receive the differential signal and output the second signal for transmission; and communicate with the external device via a pair of differential transmission lines included in the transmission line, and bias the transmission line to a first voltage level to indicate that the device is connected to the transmission line, thereby notifying the external device of a connection status of its own device by a direct current bias potential of at least one of the pair of differential transmission lines, wherein the device is a transmitting device, the transmission line is a first transmission line, the processing device notifies the external device of the connection status of its own device by the direct current bias potential of at least one of the pair of differential transmission lines, and the transmitting device further comprises a receiver for receiving an audio signal from the external device through a second transmission line, and wherein the processing device is configured to reproduce the audio signal, silencing, in case an error occurs in the second transmission line, a portion where the error has occurred; wherein the second signal includes a Sony/Philips digital interface (SPDIF) signal.
