Abstract:
1. A data receiver as a sink for receiving a transmission content from a source performing a content transmission process, the data receiver comprising: a memory for storing device information; a control unit for changing a setup of a hot plug state in which the source may be detected as one among a plurality of sources selectable by the data receiver as a contents input device, as a process of notifying the source whether the data stored in the memory of the data receiver can be obtained by the source or not, and, 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 of the data receiver is permitted to be obtained by the source, in a selection state where the source is selected by the data receiver as the contents input device, and control is performed by the control unit in the data receiver to maintain a setup showing that the hot plug state is in a state where data stored in the memory of the data receiver is permitted to be obtained by the source, in a case where the source is changed to a non-selection state by the data receiver from the selection state in which the source is selected as the contents input device, wherein the control unit is further configured to: set the hot plug state to be a “High” (High), in the selection state where the source is selected as the contents input device, to maintain the state where the hot plug state is set to be “High”, even in the case where the source is changed to the non-selection state from the selection state in which the source is selected as the contents input device, and when the source is changed to the selection state from the non-selection state in which the source is not selected as the contents input device, to change the hot plug state to a “Low” (Low) temporarily, and then to rechange the hot plug state to “High” again.
