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 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.

2. The video processing apparatus according to claim 1,

wherein in response to a second switching designation to switch the output data from the first video data synthesized with the first cursor image data generated by the external video apparatus 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.

3. 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.

4. The video processing apparatus according to claim 1,

wherein the generation unit generates graphic image data, and

wherein in response to a second switching designation to switch the output data from the first video data synthesized with the first cursor image data generated by the external video apparatus to the second video data, the generation unit generates the second cursor image data on the basis of the second position information and the graphic image data such that 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 on the basis of the graphic image data.

5. The video processing apparatus according to claim 4, 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 output data is switched.

6. 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 being operable using the pointing type remote controller, the method comprising:

inputting, by a first input unit, first video data output from the external video apparatus;

inputting, by a second input unit, second video data output from a video source not including the external video apparatus;

generating 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;

synthesizing the second video data inputted by the second input unit with the second cursor image data generated by the generating step, and outputting to the display unit the second video data synthesized with the second cursor image data;

switching 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

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) transmitting first position information regarding the specified position of the cursor image to the external video apparatus via the communication unit, and (2) controlling the switching step 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.

7. The method of controlling a video processing apparatus according to claim 6,

wherein in response to a second switching designation to switch the output data from the first video data synthesized with the first cursor image data generated by the external video apparatus to the second video data,

receiving second position information from the external video apparatus regarding a display position of the cursor image that has been displayed before the switching, and

generating the second cursor image data on the basis of the second position information.

8. The method of controlling a video processing apparatus according to claim 6, 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.

9. The method of controlling a video processing apparatus according to claim 6,

wherein the generating step generates graphic image data, and

wherein in response to a second switching designation to switch the output data from the first video data synthesized with the first cursor image data generated by the external video apparatus to the second video data, generating the second cursor image data on the basis of the second position information and the graphic image data such that 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 on the basis of the graphic image data.

10. The method of controlling a video processing apparatus according to claim 9, 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 output data is switched.
