Transmitting apparatus, stereo image data transmitting method, receiving apparatus, and stereo image data receiving method

Abstract

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.
