Patent ID: 8799939

Claim:
A video receiving apparatus that comprises one or more video input terminals to input video data, the video receiving apparatus comprising: a voltage detector configured to detect a voltage applied to a specific contact point in each of the one or more video input terminals; a control unit configured to determine whether a video transmission apparatus is connected to each of the one or more video input terminals, based on a value of the voltage detected by the voltage detector; and a memory unit connected to the control unit and configured to store information of the video transmission apparatus connected to each of the one or more video input terminals, wherein a connection state of the video transmission apparatus connected to each of the one or more video input terminals is stored in the memory unit, and wherein the control unit is configured to perform a video input switching operation, in which said video input switching operation comprises: determining whether a currently selected video input terminal of the one or more video input terminals conforms to a High Definition Multimedia Interface (HDMI) standard; based on determining that the selected video input terminal conforms to the HDMI standard, determining whether a respective video transmission apparatus is connected thereto based on the connection state; based on determining that the respective video transmission apparatus is not connected thereto, causing the respective video input terminal not to be selected and causing a switch to another video input terminal, such that a HDMI input terminal not having a video transmission apparatus connected thereto is skipped without being selected when the input switching operation is performed.
