When transmitting an input image signal and an audio signal inputted in synchronization with the input image signal, each frame in the input image signal are divided into first, second, third, and fourth subimages and pixel samples of the subimages are mapped onto image data regions of two-channel HD-SDI signals, respectively, and the audio signal is mapped onto supplementary data regions included in horizontal ancillary data spaces of any of the two-channel HD-SDI signals onto which the subimages are respectively mapped. The pixel samples mapped onto the image data regions of the two-channel HD-SDI signals are multiplexed onto an image data region of a first transfer data stream and the audio signal mapped onto the supplemental data regions included in horizontal ancillary data spaces of any of the two-channel HD-SDI signals is multiplexed onto a horizontal ancillary data space of a second transfer data stream.
