Abstract
A method for providing coordinate information to an external device and a video apparatus thereof. The coordinate information providing method includes receiving coordinate information input by a user from an input device; and transmitting a coordinate information delivery message containing the coordinate information input through the input device, to an external device connected according to a High Definition Multimedia Interface (HDMI) Consumer Electronics Control (CEC) specification. Accordingly, the video apparatus can control the external device by transferring the coordinate information to the external device.
Claims19
A coordinate information providing method comprising:
- receiving coordinate information of a pointer displayed in an external device connected according to a High Definition Multimedia Interface (HDMI) Consumer Electronics Control (CEC) specification from an input device;
- and
- transmitting a coordinate information delivery message containing the coordinate information from the input device, to the external device,
- wherein the coordinate information comprises a position change value with respect to a current position of the pointer or a position value with respect to a position of the pointer to be moved,
- wherein the coordinate information delivery message comprises a start bit, a header block, a first data block, and a second data block;
- wherein the first data block contains a command code indicative of a transferred command of the coordinate information, and the second data block contains parameter values of horizontal coordinate information and vertical coordinate information.
