Abstract

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.

Claims

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 is operable using the pointing type remote controller, the video processing apparatus comprising:

a controller configured to display 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; and

an input unit configured to receive input video data including first video data output from the external video apparatus and second video data output from a video source not including the external video apparatus,

wherein when the input video data is switched from the second video data to the first video data, the controller (1) transmits first position information regarding the specified position of the cursor image to the external video apparatus via the communication unit, (2) receives from the external video apparatus the first video data which has been combined with first cursor image data generated by the external video apparatus on the basis of the first position information such that a cursor image after the input video data is switched is displayed at a position corresponding to a display position of a cursor image that has been displayed before the input video data is switched, and (3) causes a video image including the cursor image to be displayed on the display unit on the basis of the first video data received from the external video apparatus.

2. The video processing apparatus according to claim 1, further comprising:

a generation unit configured to generate second cursor image data for displaying the cursor image in the case where the input unit is receiving the second video data; and

a synthesizing unit configured to output to the display unit synthesized video data in which the second cursor image data and the second video data have been combined.

3. The video processing apparatus according to claim 2,

wherein when the input video data is switched from the first video data to the second video data, the controller receives second position information from the external video apparatus regarding a display position of the cursor image that has been displayed before the switching, and

the generation unit generates the second cursor image data on the basis of the second position information.

4. The video processing apparatus according to claim 1, wherein the display position of the cursor image that has been displayed before the switching is the same as a display position of the cursor image displayed after the switching.

5. The video processing apparatus according to claim 2,

wherein the generation unit generates graphic image data, and

wherein a display position of the cursor image displayed on the basis of the second cursor image data is within a display region of a graphic image that is displayed after the input video data has been switched and is displayed on the basis of the graphic image data.

6. The video processing apparatus according to claim 5, wherein when the graphic image is one of a plurality of displayed graphic images, the cursor image displayed on the basis of the second cursor image data is displayed in a display region of the displayed graphic image that is closest to the cursor image that has been displayed before the input video data is switched.

7. A method of controlling 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 is operable using the pointing type remote controller, the method comprising:

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; and

receiving input video data including first video data output from the external video apparatus and second video data output from a video source not including the external video apparatus,

wherein when the input video data is switched from the second video data to the first video data, the displaying includes

(1) transmitting first position information regarding the specified position of the cursor image to the external video apparatus via the communication unit,

(2) receiving from the external video apparatus the first video data which has been synthesized with first cursor image data generated by the external video apparatus on the basis of the first position information such that a cursor image after the input video data is switched is displayed at a position corresponding to a display position of a cursor that has been displayed before the input video is switched, and

(3) causing a video image including the cursor image to be displayed on the display unit on the basis of the first video data received from the external video apparatus.
