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(Chinese):

以高数据速率启用信号传输，同时确保向后兼容性。 源设备110和宿设备120通过HDMI电缆200连接。源设备110与当前的HDMI和新的HDMI兼容。 例如，用于传输诸如视频数据的数字信号的差分信号通道的数量在当前HDMI中是三个，但是例如在新的HDMI中是六个。 在电缆200与新的HDMI兼容并且信宿设备120与新的HDMI兼容的情况下，源设备110的控制单元113控制数据发送单元112以新的HDMI操作模式操作。 在控制单元113确定至少宿设备120仅与当前HDMI兼容，或至少电缆200与当前HDMI兼容的情况下，控制单元113控制数据发送单元112在 当前的HDMI操作模式。
