Abstract
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.
