A high-speed efficient transfer of stereoscopic image information (3D information) between electronic devices can be achieved. 3D information is transferred between devices using MHL capability registers. (1) Immediately after making changes to 3D information of a capability register, the MHL sink device transmits a "SET_INT command", sets "1" in a 3D_CHG flag of the MHL source device side, and notifies the MHL source device of the 3D information. (2) The MHL source device provides an ACK response. (3) The MHL source device acknowledges that "1" is set in the 3D_CHG flag, transmits, to the MHL sink device, a "READ_DEVCAP command" to which the address information of the 3D information of the capability register is added, and reads only the 3D information from the capability register. An elaborate 3D control can be achieved by performing 3D information transfer between devices using MHL scratchpad registers. |
