  • Patent number: 10015468
    Abstract: Transmission of stereo image data may be performed between devices, where a source device receives E-EDID from a sink device via DDC of an HDMI cable. This E-EDID contains information on 3D image data transmission modes supportable by the sink device. Based on 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 supportable by the sink device. The source device transmits 3D image data in the selected transmission mode to the sink device. The source device transmits information on the transmission mode for the 3D image data, 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 and right eye image data.

    Abstract: To discriminate whether a cable in conformity with a conventional standard or a cable in conformity with a new standard is connected. An HPD signal line (902) has, on an expanded HDMI sink apparatus (402) side circuit, a pull-up resistor (911) between the HPD signal line (902) and a voltage supply and a pull-down resistor (913) between the HPD signal line (902) and the ground, and a reserved line (903) has, on the expanded HDMI sink apparatus (402) side circuit, a pull-down resistor (914) between the reserved line (903) and a ground, and within a new HDMI cable (901), a pull-up resistor (912) between the reserved line (903) and a voltage supply of an expanded HDMI source apparatus (401). The expanded HDMI sink apparatus compares a voltage at a test point (19) on the reserved line (903) on the expanded HDMI sink apparatus (402) side with a reference voltage by using a voltage comparator (916).
