Abstract
An electronic device to determine a type of digital interface between a source device and a sink device. A control unit of the sink device may include a determining unit which determines whether or not the source device is connected to this sink device, and whether or not the digital interface of a data transmission unit of the source device is a HDMI standard or a new standard. When a data reception unit can handle both the HDMI standard and new standard, based on the determination result of the determining unit, a control unit may switch the operation of the data reception unit so as to perform an operation in accordance with the digital interface of the data transmission unit of the source device. A connector unit for connecting the devices which may operate using the digital interfaces of HDMI and the new standard can be shared.
