Abstract
A video receiving apparatus is provided. The video receiving apparatus may have a video input terminal to input video data, and may include a voltage detector configured to detect a voltage applied to a specific contact point in the video input terminal; and a control unit configured to determine whether a video transmission apparatus is connected to the video input terminal through a predetermined cable, based on a value of the voltage detected by the voltage detector.
Claims7
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.
A method of receiving video using a television device that comprises a display and one or more video input terminals to input video data, comprising:
- detecting a voltage applied to a specific contact point in each of the one or more video input terminals;
- determining whether a video transmission apparatus is connected to each of the one or more video input terminals, based on a value of the detected voltage;
- storing in a memory unit connected to the control unit, 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
- performing a video input switching operation, comprising:
- 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.
