发明名称 Video processing apparatus and method of controlling the same
摘要 A video processing apparatus is provided that is controlled such that the display position of a cursor for a pointing type remote controller does not change when input is switched in a configuration where the video processing apparatus is connected to an external video apparatus. When input video data is switched, a controller transmits position information regarding the display position of a cursor image to the external video apparatus via a communication unit. The controller receives cursor image data generated by the external video apparatus from the external video apparatus and causes a cursor image, based on the cursor image data, to be displayed on a display unit, such that a cursor image after the input video data is switched is displayed at a position corresponding to the display position of a cursor image that has been displayed before the input video data is switched.

主权项 1. A video processing apparatus connected via a communication unit to an external video apparatus operable using a pointing type remote controller, the video processing apparatus being operable using the pointing type remote controller, the video processing apparatus comprising: a first input unit configured to input first video data output from the external video apparatus; a second input unit configured to input second video data output from a video source not including the external video apparatus; a generation unit configured to generate second cursor image data for displaying a cursor image at a specified position on a display screen of a display unit in accordance with an operation of the pointing type remote controller only when an output unit outputs the second video data to the display unit; a synthesizing unit configured to synthesize the second video data inputted by the second input unit with the second cursor image data generated by the generation unit, and output to the display unit the second video data synthesized with the second cursor image data; a switching unit configured to switch output data being outputted to a display unit between the first video data inputted by the first input unit and the second video data synthesized with the second cursor image data; and a controller configured to, in response to a first switching designation to switch the output data from the second video data synthesized with the second cursor image data to the first video data, (1) transmit first position information regarding the specified position of the cursor image to the external video apparatus via the communication unit, and (2) control the switching unit to switch the output data from the second video data synthesized with the second cursor image data to the first video data synthesized with first cursor image data generated by the external video apparatus on the basis of the first position information.
