Abstract: High-quality content reproduction is to be realized. A transmission clock is supplied from a sink (repeater) device to a source device via a clock signal line. The source device sends content data to the sink (repeater) device via a predetermined number of differential signal lines in synchronization with the transmission clock supplied from the sink (repeater) device. High-quality content reproduction can be performed in the sink (repeater) device, without the use of any additional lines other than the differential signal lines and the clock signal line. For example, upon receipt of a transmission clock supply request from the source device, the sink (repeater) device supplies the transmission clock to the source device.

The present invention may be applied to HDMI®, for example.

A control unit of the sink device may include a determining unit which determines whether or not the source device is connected to this sink device, and whether or not the digital interface of a data transmission unit of the source device is a HDMI standard or a new standard. When a data reception unit can handle both the HDMI standard and new standard, based on the determination result of the determining unit, a control unit may switch the operation of the data reception unit so as to perform an operation in accordance with the digital interface of the data transmission unit of the source device. A connector unit for connecting the devices which may operate using the digital interfaces of HDMI and the new standard can be shared.

Abstract: To enable signal transmission at a high data rate while securing backward compatibility. A source device 110 and a sink device 120 are connected by an HDMI cable 200. The source device 110 is compatible with both current HDMI and new HDMI. The number of differential signal channels for transmitting digital signals such as video data is three in the current HDMI, but is six in the new HDMI, for example. In a case where the cable 200 is compatible with the new HDMI, and the sink device 120 is compatible with the new HDMI, a control unit 113 of the source device 110 controls a data transmitting unit 112 to operate in a new HDMI operating mode. In a case where the control unit 113 determines that at least the sink device 120 is compatible only with the current HDMI, or at least the cable 200 is compatible with the current HDMI, the control unit 113 controls the data transmitting unit 112 to operate in a current HDMI operating mode.

Abstract: Transmission of a high-definition video signal or the like that requires a wide transmission band is to be realized. A video signal is divided by frames to generate divisional video signals, and the respective divisional video signals are transmitted to an external device via transmission channels independent of one another. Transmission of a high-definition video signal or the like that requires a wider transmission band than the transmission band of one transmission channel can be realized in a preferred manner. For each frame, first information indicating the existence of the other divisional video signal to be combined therewith and second information for establishing synchronization with the other divisional video signal to be combined therewith are added to the divisional video signals to be transmitted by a data transmitting unit. In the external device, a reception video signal can be easily obtained by arranging the divisional video signals in the frame order.
