| description | A transmitting device includes a transmission side control data memory. A receiving device includes a receiving side control data memory. In an operation state, EDID, a device key for and HDCP and the like are stored in the receiving side control data memory. Subsequently, the EDID and information necessary for HDCP authentication are copied from the receiving side control data memory to the transmission side control data memory through the DDC. A transmission controller accesses the transmission side control data memory and executes plug-and-play and HDCP authentication. The DDC realizes a one-to-one connection between the transmitting device and the receiving device. Thus, waveform distortion can be minimized and the length of a cable can be increased in a simple manner. |
