Successful communication required between external devices is achieved. A content data processing unit is connected to an external device through a first line. A communication unit is connected to the external device through a second line. The content data processing unit represents, for example, a content data transmitting unit that transmits content data to the external device, or a content data receiving unit that receives the content data from the external device. The communication unit transmits an inquiry signal to the external device through the second line in a state in which the first line is unavailable. For example, in a case where the interface unit is in a standby state, it is possible to inquire a required item to the external device while the state is maintained. Since it is possible to decrease power consumption of the external device as much as possible, it is possible to contribute to saving of energy of the external device.

Stereoscopic image information (3D information) can be efficiently transmitted between electronic devices at high speed. Using a capability register (Capability Register) of MHL, the 3D information is transmitted between devices. (1) An MHL sink device transmits a 'SET_INT command' immediately after changing the 3D information of the capability register, a 3D_CHG flag of an MHL source device side is set to '1' and the MHL sink device notifies the MHL source device of the 3D information. (2) The MHL source device responds ACK. (3) The MHL source device recognizes that the 3D_CHG flag is set to 1, transmits a &#x201c;READ_DEVCAP command&#x201d; in which address information of the 3D information of the capability register is added to the MHL sink device and reads only the 3D information from the capability register. Using a scratchpad register of MHL, the 3D information is transmitted between the devices and detailed 3D control is performed.

To provide an electronic apparatus capable of easily detecting a terminal that forms a loop connection state with a simplified configuration. A control unit counts the number of broadcast packet supplied from a switching hub to a communication unit within a predetermined time period and determines whether the number of packets exceeds a threshold value (ST, ST). If the number of packets exceeds the threshold value, the control unit determines that an abnormal connection state occurs, that is, a loop is detected and starts a process in which the control unit identifies a network terminal that forms the loop connection state (ST, ST). The control unit counts the number of broadcast packets that reach each of the network terminals, that is, broadcast packets input to each port of the switching hub. Thereafter, the control unit determines whether the network terminal that has received the number of packets exceeding the threshold value is present, that is, whether an abnormally connected terminal is present (ST, ST). If an abnormally connected terminal is present, the control unit displays a message indicating abnormal connection, the abnormally connected terminal, and a message prompting connection change (ST).
