Abstract
A data receiver as a sink for receiving a transmission content from a source performing a content transmission process, the data receiver includes a memory for storing device information; and a control unit for changing a setup of a hot plug state in which the source may be detected, as a process of notifying the source whether the data stored in the memory can be obtained or not. The control unit is arranged to set the hot plug state as a setup indicative of being in a state where the data stored in the memory is permitted to be obtained, in a selection state where the source is selected as a contents input device, and control is performed to maintain a setup showing that the hot plug state is in a state where data stored in the memory is permitted to be obtained, in a case where the source is changed to a non-selection state from a selection state in which the source is selected as the contents input device.
