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.

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

The present invention makes it possible to perform transmission of stereo image data between devices in a favorable manner. A source device (disc player) receives E-EDID from a sink device (television receiver) via DDC of an HDMI cable. 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.

There is provided a transmitter device including an interface unit that is an interface for connection to a receiver device via a transmission path, a pre-emphasis unit configured to generate a pre-emphasis signal, the pre-emphasis signal being obtained by adding to an input signal another signal for compensating for a high-frequency component of the input signal, and a transmission control unit configured to acquire identification information indicating whether the receiver device is capable of performing a process of receiving the pre-emphasis signal, switch the receiver device to a state in which the receiver device is capable of performing the process of receiving the pre-emphasis signal in accordance with the identification information, and control the pre-emphasis unit to generate the pre-emphasis signal.

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 () has, on an expanded HDMI sink apparatus () side circuit, a pull-up resistor () between the HPD signal line () and a voltage supply and a pull-down resistor () between the HPD signal line () and the ground, and a reserved line () has, on the expanded HDMI sink apparatus () side circuit, a pull-down resistor () between the reserved line () and a ground, and within a new HDMI cable (), a pull-up resistor () between the reserved line () and a voltage supply of an expanded HDMI source apparatus (). The expanded HDMI sink apparatus compares a voltage at a test point () on the reserved line () on the expanded HDMI sink apparatus () side with a reference voltage by using a voltage comparator (). A CPU of the expanded HDMI sink apparatus () determines, when an output from the voltage comparator () is High, a normal state where the new HDMI cable () is inserted, and when an output from the voltage comparator () is Low, determines a state where a conventional HDMI cable () is erroneously inserted.
