The present invention makes it possible to perform transmission of stereo image data between devices in a favorable manner. A source device (disc player 210) receives E-EDID from a sink device (television receiver 250) via DDC of an HDMI cable 350. This E-EDID contains information on 3D image data transmission modes that can be supported by the sink device. On the basis of the information on 3D image data transmission modes from the sink device, the source device selects a predetermined transmission mode from among the 3D image data transmission modes that can be supported by the sink device. The sink device transmits 3D image data in the selected transmission mode to the sink device. For the convenience of processing in the sink device, the source device transmits information on the transmission mode for the 3D image data transmitted, to the sink device by using an AVI InfoFrame packet or the like. The sink device processes the 3D image data received from the source device in accordance with its transmission mode, thereby obtaining left eye and right eye image data.
